質問 # 39
IBA probes analyze telemetry data from specified devices within a blueprint. Which component Identities devices that supply data tor a specific probe?

• A. graph query
• B. data selector
• C. search engine
• D. processor

正解：A

解説：
A graph query is a component that identifies devices that supply data for a specific probe. A graph query is an expression that matches nodes in the Apstra graph database based on their attributes, such as device name, role, type, or tag. A graph query can be used to select the source devices for the input processors of a probe, as well as to filter the data by device attributes in the subsequent processors of a probe12. References:

質問 # 40
In the Juniper Apstra Ul. you are creating a VNI pool for virtual networks.
In this scenario, which VNI range is acceptable?

• A. The valid VNI range is 1 through 10000.
• B. The valid VNI range is 2 through 4096.
• C. The valid VNI range is 4096 through 16777214.
• D. Any range is acceptable for the VNI pool.

正解：C

解説：
In the Juniper Apstra UI, you can create VNI pools for virtual networks that use VXLAN encapsulation in the overlay network. A VNI pool is a resource pool that contains a range of VNIs that can be assigned to the virtual networks. The valid VNI range for a VNI pool is 4096 through 16777214, according to the VXLAN standard1. Therefore, the statement B is correct in this scenario.
The following three statements are incorrect in this scenario:
* Any range is acceptable for the VNI pool. This is not true, because the VNI range has a lower and upper limit defined by the VXLAN standard1. The lower limit is 4096, and the upper limit is 16777214. Any VNI outside this range is invalid and cannot be used for VXLAN encapsulation.
* The valid VNI range is 2 through 4096. This is not true, because the VNI range does not start from 2, but from 4096. The VNIs from 2 to 4095 are reserved and cannot be used for VXLAN encapsulation1.
* The valid VNI range is 1 through 10000. This is not true, because the VNI range does not include 1, which is also reserved and cannot be used for VXLAN encapsulation1. The VNI range also does not end at 10000, but at 16777214, which is the maximum possible value for a 24-bit VNI field1.

質問 # 41
You want to keep virtual networks isolated from each other within the Juniper Apstra system.
In this scenario, what are three ways to accomplish this task? (Choose three.)

• A. Use Connectivity Templates to block access within the same Routing Zone.
• B. Disable IPv4 connectivity when creating the virtual network within the same Routing Zone.
• C. Put each network in different Routing Zones.
• D. Enable Security Policy for virtual networks in the same Routing Zone.
• E. Disable Route Target exports when creating the Routing Zones.

正解：A、C、D

解説：
To keep virtual networks isolated from each other within the Juniper Apstra system, you can use one or more of the following methods:
* Enable Security Policy for virtual networks in the same Routing Zone. This allows you to define rules that control the traffic flow between different virtual networks within the same routing zone. You can specify the source and destination virtual networks, the protocol, the port, and the action (allow or deny) for each rule. The security policy is applied on the ingress interface of the leaf devices1.
* Use Connectivity Templates to block access within the same Routing Zone. This allows you to customize the connectivity between different racks within the same routing zone. You can create templates that define the link type, the routing protocol, and the access control list(ACL) for each rack pair. The ACL can be used to filter the traffic based on the source and destination IP addresses, the protocol, and the port2.
* Put each network in different Routing Zones. This allows you to create logical boundaries between different virtual networks based on the route target (RT) values. A routing zone is a collection of virtual networks that share the same RT for importing and exporting routes. Virtual networks in different routing zones do not exchange routes with each other, unless you configure remote EVPN gateways to connect them3. References:

質問 # 42
Exhibit.

Referring to the exhibit, which role does Device A serve in an IP fabric?

• A. server
• B. spine
• C. leaf
• D. super spine

正解：B

解説：
Device A serves as a spine in an IP fabric. An IP fabric is a network architecture that uses a spine-leaf topology to provide high performance, scalability, and reliability for data center networks. A spine-leaf topology consists of two layers of devices: spine devices and leaf devices. Spine devices are the core devices that interconnect all the leaf devices using equal-cost multipath (ECMP) routing. Leaf devices are the edge devices that connect to the servers, storage, or other network devices. In the exhibit, Device A is connected to four leaf devices using multiple links, which indicates that it is a spine device. The other options are incorrect because:
* A. leaf is wrong because a leaf device is an edge device that connects to the servers, storage, or other network devices. In the exhibit, Device A is not connected to any servers, storage, or other network devices, but only to four leaf devices, which indicates that it is not a leaf device.
* C. super spine is wrong because a super spine device is a higher-level device that interconnects multiple spine devices in a large-scale IP fabric. A super spine device is typically used when the number of leaf devices exceeds the port density of a single spine device. In the exhibit, Device A is not connected to any other spine devices, but only to four leaf devices, which indicates that it is not a super spine device.
* D. server is wrong because a server device is a compute or storage device that connects to a leaf device in an IP fabric. A server device is typically the end host that provides or consumes data in the network.
In the exhibit, Device A is not connected to any leaf devices, but only to four leaf devices, which indicates that it is not a server device. References:

質問 # 43
Exhibit.

In the EVPN-VXLAN data center fabric bridged overlay architecture shown in the exhibit, the servers are connected to Lead and Leat6 using the same virtual network identifier (VNI).
Which two statements are correct in this scenario? (Choose two.)

• A. Loopback IPv4 addresses must be advertised into the EBGP underlay from leaf and spine devices.
• B. The underlay must use IRB interfaces.
• C. The underlay EBGPpeering'smust be established between leaf and spine devices.
• D. The underlay must be provisioned with PIMv2.

正解：A、C

解説：
In the EVPN-VXLAN data center fabric bridged overlay architecture shown in the exhibit, the servers are connected to Leaf1 and Leaf6 using the same virtual network identifier (VNI). This means that the servers belong to the same Layer 2 domain and can communicate with each other using VXLAN tunnels across the fabric. The underlay network provides the IP connectivity between the leaf and spine devices, and it uses EBGP as the routing protocol. Therefore, the following two statements are correct in this scenario:
* Loopback IPv4 addresses must be advertised into the EBGP underlay from leaf and spine devices. This is because the loopback addresses are used as the source and destination IP addresses for the VXLAN tunnels, and they must be reachable by all the devices in the fabric. The loopback addresses are also used as the router IDs and the BGP peer addresses for the EBGP sessions.
* The underlay EBGP peering's must be established between leaf and spine devices. This is because the EBGP sessions are used to exchange the underlay routing information and the EVPN routes for the overlay network. The EBGPsessions are established using the loopback addresses of the devices, and they follow a spine-and-leaf topology, where each leaf device peers with all the spine devices, and each spine device peers with all the leaf devices.
The following two statements are incorrect in this scenario:
* The underlay must use IRB interfaces. This is not true, because the underlay network does not provide any Layer 3 gateway functionality for the overlay network. The IRB interfaces are used to provide inter-VXLAN routing within the fabric, which is not the case in the bridged overlay architecture. The IRB interfaces are used in the edge-routed bridging (ERB) or the centrally-routed bridging (CRB) architectures, which are different from the bridged overlay architecture.
* The underlay must be provisioned with PIMv2. This is not true, because the underlay network does not use multicast for the VXLAN tunnels. The VXLAN tunnels are established using EVPN, which uses BGP to distribute the MAC and IP addresses of the end hosts and the VTEP information of the devices.
EVPN eliminates the need for multicast in the underlay network, and it provides optimal forwarding and fast convergence for the overlay network.

質問 # 44
Exhibit.

Referring to the exhibit, how many broadcast domains will an Ethernet frame pass through when traversing the IP fabric from Server A to Server B?

• A. 0
• B. 1
• C. 2
• D. 3

正解：D

解説：
Referring to the exhibit, the image shows a simplified diagram of an IP fabric network connecting two servers, labeled as Server A and Server B. The IP fabric is a network architecture that uses a Clos topology to provide high bandwidth, low latency, and scalability for data center networks. The IP fabric consists of spine and leaf devices that use BGP as the routing protocol and VXLAN as the overlay technology1.
A broadcast domain is a logical portion of a network where any device can directly transmit broadcast frames to other devices at the data link layer (OSI Layer 2). A broadcast frame is a frame that has a destination MAC address of all ones (FF:FF:FF:FF:FF:FF), which means that it is intended for all devices in the same broadcast domain. A broadcast domain is usually bounded by a router, which does not forward broadcast frames to other networks2.
In the exhibit, there are two broadcast domains that an Ethernet frame will pass through when traversing the IP fabric from Server A to Server B. The first broadcast domain is the one that contains Server A and the leaf device that it is connected to. The second broadcast domain is the one that contains Server B and the leaf device that it is connected to. The IP fabric itself is not a broadcast domain, because it uses IP routing and VXLAN encapsulation to transport the Ethernet frames over the Layer 3 network. Therefore, the statement C is correct in this scenario.
The following three statements are incorrect in this scenario:
* A. 1. This is not true, because there are not one, but two broadcast domains that an Ethernet frame will pass through when traversing the IP fabric from Server A to Server B. The IP fabric itself is not a broadcast domain, because it uses IP routing and VXLAN encapsulation to transport the Ethernet frames over the Layer 3 network.
* B. 4. This is not true, because there are not four, but two broadcast domains that an Ethernet frame will pass through when traversing the IP fabric from Server A to Server B. The spine devices and the leaf devices that are not connected to the servers are not part of the broadcast domains, because they use IP routing and VXLAN encapsulation to transport the Ethernet frames over the Layer 3 network.
* D. 3. This is not true, because there are not three, but two broadcast domains that an Ethernet frame will pass through when traversing the IP fabric from Server A to Server B. The IP fabric itself is not a broadcast domain, because it uses IP routing and VXLAN encapsulation to transport the Ethernet frames over the Layer 3 network.

質問 # 45
You are using Juniper Apstra to design a data center fabric.
In this scenario, which object type associates a specific vendor model to a logical device?

• A. interface map
• B. device profiles
• C. agent profiles
• D. templates

正解：B

解説：
Device profiles are objects that associate a specific vendor model to a logical device in Juniper Apstra. Device profiles contain extensive hardware model details, such as form factor, ASIC, CPU, RAM, ECMP limit, and supported features. Device profiles also define how configuration is generated, how telemetry commands are rendered, and how configuration is deployed on a device. Device profiles enable the Apstra system to render and deploy the configuration according to the Apstra Reference Design12. References:
* Device Profiles
* Juniper Device Profiles

質問 # 46
Exhibit.

Referring to the exhibit, what is the minimum information you must add to create a new routing zone?

• A. VRF Name only
• B. VRF Name, VLAN ID.AndVNI
• C. VRF Name and Routing policies
• D. VRF Name, VLAN ID, VNI, Routing Policies

正解：B

解説：
To create a new routing zone, you must specify the VRF Name, VLAN ID, and VNI for the routing zone.
These are the mandatory fields in the user interface shown in the exhibit. The VRF Name is the name of the L3 domain that isolates the IP traffic of the routing zone from other routing zones. The VLAN ID is the identifier for the VLAN tagged Layer 3 links on external connections. The VNI is the VxLAN Network Identifier associated with the routing zone. The Routing Policies are optional fields that allow you to configure import and export route targets for the routing zone. These are onlyapplicable for EVPN routing zones, which use MP-EBGP as the overlay control protocol. The other options are incorrect because:
* A. VRF Name only is wrong because you also need to specify the VLAN ID and VNI for the routing zone.
* B. VRF Name and Routing policies is wrong because you also need to specify the VLAN ID and VNI for the routing zone. Routing policies are optional and only relevant for EVPN routing zones.
* D. VRF Name, VLAN ID, VNI, Routing Policies is wrong because Routing Policies are optional and not required to create a new routing zone. References:

質問 # 47
Juniper Apstra has indicated an anomaly with respect to cabling.
What are two ways to remediate the issue? (Choose two.)

• A. Have Apstra autoremediate the cabling map using LLDP.
• B. Manually edit the cabling map.
• C. Set the invalid ports to a disabled state.
• D. Redeploy the errant device.

正解：A、B

解説：
A cabling anomaly is an issue that occurs when the physical connections between the devices in the data center fabric do not match the expected connections based on the Apstra Reference Design. A cabling anomaly can cause problems such as incorrect routing, suboptimal traffic flow, or device isolation. To remediate the issue, you can use one or both of the following methods:
* Manually edit the cabling map. This allows you to override the Apstra-generated cabling and specify the correct connections between the devices. You can use the Apstra UI or the Apstra CLI to edit the cabling map and apply the changes to the fabric12.
* Have Apstra autoremediate the cabling map using LLDP. This allows Apstra to collect LLDP data from the devices and use it to update the cabling map automatically. LLDP is a protocol that allows devices to exchange information about their identity, capabilities, and neighbors. Apstra can use the LLDP data to detect and correct any cabling errors in the fabric34. References:

質問 # 48
What is the purpose of using a routing zone inside Juniper Apstra software?

• A. A routing zone is defined to secure the routing protocols.
• B. A routing zone is used to enable the communication between two VNIs within a VRF.
• C. A routing zone is used to enable L4-L7 inspection inside the fabric.
• D. A routing zone defined at the Apstra manager level requires firewalls to be deployed.

正解：B

解説：
According to the Juniper documentation1, a routing zone is an L3 domain, the unit of tenancy in multi-tenant networks. You create routing zones for tenants to isolate their IP traffic from one another, thus enabling tenants to re-use IP subnets. In addition to being in its own VRF, each routing zone can be assigned its own DHCP relay server and external system connections. You can create one or more virtual networks within a routing zone, which means a tenant can stretch its L2 applications across multiple racks within its routing zone. For virtual networks with Layer 3 SVI, the SVI is associated with a Virtual Routing and Forwarding (VRF) instance for each routing zone isolating the virtual network SVI from other virtual network SVIs in other routing zones. Therefore, the correct answer is D. A routing zone is used to enable the communication between two VNIs within a VRF. A routing zone is not used for L4-L7 inspection, securing routing protocols, or requiring firewalls. Those are not the purposes of a routing zone in Juniper Apstra software. References: Routing Zones

質問 # 49
You are working with a three-stage IP fabric using EBGP for peering.
In this scenario, which two actions are required to implement ECMP? (Choose two.)

• A. Usea load balancing policy applied to the forwarding table as an export policy.
• B. Use a load balancing policy applied to BGP as an export policy.
• C. Use the multipath multiple-as BGP parameter.
• D. Use a load balancing policy applied lo BGP as an import policy.

正解：B、C

解説：
To implement ECMP in IP fabric using EBGP, you need to enable BGP to install multiple equal-cost paths in the routing table and to advertise them to the peers. The following actions are required to achieve this:
* B. Use a load balancing policy applied to BGP as an export policy. This is true because you need to apply a load balancing policy to BGP as an export policy to allow BGP to advertise multiple paths to the same destination to the peers. By default, BGP only advertises the best path to the peers, which prevents ECMP. A load balancing policy can be configured to match the desired routes and set the multipath attribute to true. This will enable BGP to advertise up to the maximum number of paths configured by the maximum-paths command. For example, the following configuration applies a load balancing policy to BGP as an export policy for the neighbor 10.10.10.1:
policy-statement load-balance { term 1 { from { route-filter 192.168.0.0/16 exact; } then { multipath; accept; }
} } protocols { bgp { group ebgp { type external; neighbor 10.10.10.1 { export load-balance; } } } }
* C. Use the multipath multiple-as BGP parameter. This is true because you need to enable the multipath multiple-as BGP parameter to allow BGP to install multiple paths from different autonomous systems in the routing table. By default, BGP only installs multiple paths from the same autonomous system, which limits ECMP. The multipath multiple-as parameter can be configured under the BGP group or neighbor level. This will enable BGP to install up to the maximum number of paths configured by the maximum-paths command. For example, the following configuration enables the multipath multiple-as parameter for the BGP group ebgp:
protocols { bgp { group ebgp { type external; multipath multiple-as; } } } The following options are incorrect because:
* A. Use a load balancing policy applied to the forwarding table as an export policy is wrong because applying a load balancing policy to the forwarding table does not affect the BGP advertisement or installation of multiple paths. A load balancing policy applied to the forwarding table only affects how the traffic isdistributed among the multiple paths in the forwarding table. It does not enable ECMP in BGP.
* D. Use a load balancing policy applied to BGP as an import policy is wrong because applying a load balancing policy to BGP as an import policy does not affect the BGP advertisement of multiple paths. A load balancing policy applied to BGP as an import policy only affects how the BGP routes are accepted or rejected from the peers. It does not enable ECMP in BGP. References:

質問 # 50
Which statement about Juniper Apstra role-based access control is correct?

• A. The administrator role is the only predefined role.
• B. The viewer role is predefined and can be deleted.
• C. The user role can create roles.
• D. The administrator role can see all permissions.

正解：D

解説：
Juniper Apstra role-based access control (RBAC) is a feature that allows you to specify access permissions for different users based on their roles. RBAC servers are remote network servers that authenticate and authorize network access based on roles assigned to individual users within an enterprise1. Juniper Apstra has four predefined user roles: administrator, device_ztp, user, and viewer2. The administrator role is the most powerful role, and it can see all permissions and perform all actions in the Apstra software application. The administrator role can also create, clone, edit, and delete user roles, except for the four predefined user roles, which cannot be modified2. Therefore, the statement that the administrator role can see all permissions is correct.
The following three statements are incorrect in this scenario:
* The viewer role is predefined and can be deleted. This is not true, because the viewer role is one of the four predefined user roles, and it cannot be deleted. The viewer role is the most restricted role, and it can only view the network information and configuration, but not make any changes2.
* The user role can create roles. This is not true, because the user role is one of the four predefined user roles, and it cannot create roles. The user role can perform most of the network configuration and management tasks, but it cannot access the platform settings or the user management features2.
* The administrator role is the only predefined role. This is not true, because there are four predefined user roles, not just one. The other three predefined user roles are device_ztp, user, and viewer2.

質問 # 51
What is the purpose of a Juniper Apstra rack?

• A. It stores IP address and ASN pool information.
• B. It stores information on how leaf nodes connect to generic devices
• C. It stores device port data rates and vendor information.
• D. It stores information on how pods connect to super spines.

正解：B

解説：
A Juniper Apstra rack is a physical entity that contains one or more network devices, such as leaf nodes, access switches, or generic systems. A rack is used to organize and manage the network devices in the Apstra software application. A rack has the following characteristics:
* It stores information on how leaf nodes connect to generic devices. This is because a rack can include generic systems, which are devices that are not managed by Juniper Apstra, but are connected to the network. A generic system can be a server, a firewall, a load balancer, or any other device that has a networkinterface. A rack stores the information on how the leaf nodes, which are the devices that provide access to the end hosts, connect to the generic devices, such as the port number, the link speed, the LAG mode, and the roles1.
* It has a rack type, which defines the type and number of leaf devices, access switches, and/or generic systems that are used in the rack. A rack type is a resource that is created in the data center design phase, and it does not specify the vendor or the model of the devices. A rack type can be predefined or custom-made, and it can be used to create multiple racks with the same structure and configuration2.
* It has a rack build, which assigns the specific vendor and model of the devices to the rack. A rack build is created in the staged phase, and it uses the rack type as a template. A rack build can also assign the resources, such as the IP addresses, the ASNs, and the VNIs, to the devices in the rack3.
* It has a rack deployment, which applies the network configuration and services to the devices in the rack. A rack deployment is performed in the active phase, and it uses the rack build as a reference. A rack deployment can also monitor the network performance and compliance of the devices in the rack4.
The following three statements are incorrect in this scenario:
* It stores information on how pods connect to super spines. This is not true, because a rack does not store any information on the pod or the super spine level of the network. A pod is a cluster of leaf and spine devices that form a 3-stage Clos topology, and a super spine is a device that connects multiple pods in a
5-stage Clos topology. A rack only stores information on the leaf and the access level of the network1.
* It stores IP address and ASN pool information. This is not true, because a rack does not store any information on the IP address and ASN pools. IP address and ASN pools are resources that are created in the data center design phase, and they contain a range of IP addresses and ASNs that can be assigned to the devices and the virtual networks. A rack only uses the IP address and ASN pools to assign the resources to the devices in the rack build2.
* It stores device port data rates and vendor information. This is not true, because a rack does not store any information on the device port data rates and vendor information. The device port data rates and vendor information are specified in the rack build, which assigns the specific vendor and model of the devices to the rack. A rack only uses the rack build to apply the network configuration and services to the devices in the rack deployment3.

質問 # 52
What are two system-defined user roles that are available in Juniper Apstra? (Choose two.)

• A. viewer
• B. authorized
• C. root
• D. user

正解：A、D

解説：
Juniper Apstra provides four system-defined user roles that are available in the Apstra GUI environment. They are: administrator, device_ztp, viewer, and user1. Based on the web search results, we can infer the following statements:
* viewer: This role includes permissions to only view various elements in the Apstra system, such as blueprints, devices, design, resources, external systems, platform, and others. Users with this role cannot create, edit, or delete any element12.
* user: This role includes permissions to view and edit various elements in the Apstra system, such as blueprints, devices, design, resources, external systems, platform, and others. Users with this role cannot create or delete any element12.
* authorized: This is not a system-defined user role in Juniper Apstra. It is a term used to describe users who have been authenticated by an external system, such as LDAP, Active Directory, TACACS+, or RADIUS3.
* root: This is not a system-defined user role in Juniper Apstra. It is a term used to describe the superuser account on a Linux system, which has full access to all commands and files. Creating a user in the Apstra GUI does not provide that user access to the Apstra platform via SSH. To access the Apstra platform via SSH, you must create a local Linux system user4. References:

質問 # 53
You want to apply a configlet to a specific device using Juniper Apstra. Which two parameters would be used to accomplish this task? (Choose two.)

• A. hostname
• B. port group
• C. form factor
• D. tags

正解：A、D

解説：
To apply a configlet to a specific device using Juniper Apstra, you need to specify the device's hostname and tags. The hostname is the unique identifier of the device in the Apstra system, and the tags are the labels that you can assign to the device to group it with other devices that share the same characteristics. You can use the hostname and tags to filter the devices that you want to apply the configlet to in the blueprint catalog12.

質問 # 54
You are adding a new switch to Juniper Apstra software. The Managed Devices page shows the "0 OS-Quarantined" status. What is the proper next step to make the device ready for use in a blueprint?

• A. Install the agent for the device.
• B. Take the device out of maintenance mode.
• C. Take the device out of drain state.
• D. Acknowledge the device.

正解：D

解説：
When a new switch is added to Juniper Apstra software, it initially shows the "0 OS-Quarantined" status, which means that the device is not yet managed by Apstra and has not been assigned to any blueprint. The proper next step to make the device ready for use in a blueprint is to acknowledge the device, which is a manual action that confirms the device identity and ownership. Acknowledging the device changes its status to
"OOS-Ready", which means that the device is ready to be assigned to a blueprint and deployed12. References

質問 # 55
What is the function of the Revert button in the Juniper Apstra Ul?

• A. The Revert button performs a rollback 0 on Juniper devices in the fabric.
• B. The Revert button will rollback to the previous configuration of a specified device.
• C. The Revert button will undo the last change made to the configuration.
• D. The Revert button deletes any uncommitted changes within Apstra.

正解：D

解説：
According to the Juniper documentation1, the Revert button is located on the Uncommitted tab of the blueprint page. The Uncommitted tab shows the changes that have been staged but not yet committed to the network. The Revert button allows you to discard any uncommitted changes and revert to the last committed state of the blueprint. This is useful if you want to cancel the changes that you have made or if you want to start over with a fresh slate. Therefore, the correct answer is B. The Revert button deletes any uncommitted changes within Apstra. References: Commit / Revert Changes to Blueprint | Apstra 4.2 | Juniper Networks
