質問 # 25
You are helping an onsite network technician bring up an Aruba 9004 gateway with ZTP for a branch office The technician was to plug in any port for the ZTP process to start Thirty minutes after the gateway was plugged in new users started to complain they were no longer able to get to the internet. One user who reported the issue stated their IP address is 172.16 0.81 However, the branch office network is supposed to be on 10.231 81.0/24.
What should the technician do to alleviate the issue and get the ZTP process started correctly?
- A. Move the cable on the gateway to G0/0/1. and add the device's MAC and Serial number in Central
- B. Move the cable on the gateway from port G0/0V1 tc port G0 0.0
- C. Turn off the DHCP scope on the gateway, and set DNS correctly on the gateway to reach Aruba Activate
- D. Factory default and reboot the gateway to restart the process.
正解：B
解説：
Explanation
Aruba 9004 gateway supports ZTP on port G0/0/0 by default1. If the gateway is connected to a different port, such as G0/0/V1, it will not be able to communicate with Aruba Activate and Aruba Central, which are required for ZTP2. Moreover, port G0/0/V1 is configured as a DHCP server by default, which can cause IP address conflicts with the existing network3. Therefore, the technician should move the cable on the gateway to port G0/0/0, which will allow the gateway to obtain an IP address from the network DHCP server and start the ZTP process. The other options are not correct because they will not solve the issue or enable ZTP. For example, option D will not work because factory defaulting and rebooting the gateway will not change the port configuration or behavior3.

Explanation
The component that is used by the Aruba Network Analytics Engine (NAE) is D. Current State Database.
The Current State Database is a database that stores the configuration and state information of the switch, such as interfaces, VLANs, routing protocols, statistics, and more. The NAE can access this database through the AOS-CX REST API and monitor the values of any data point using monitors. The NAE can also track the history of the values in a time-series database and correlate them with network events or configuration changes1. The Current State Database provides NAE with direct visibility into the entire current state of the device, which enables intelligent troubleshooting and automation of network tasks1.
The other options are incorrect because:
A: JSON-based scripts: JSON is a data format that is used to exchange information between applications. It is not a scripting language that can be used by NAE. NAE scripts are written in Python, which is a popular and powerful programming language1.
B: Lisp-based agents: Lisp is a family of programming languages that are mainly used for artificial intelligence and functional programming. It is not a language that can be used by NAE. NAE agents are instances of scripts that run on the switch and collect relevant network information and trigger alerts or actions1.
C: Ruby-based scripts: Ruby is a general-purpose programming language that is known for its expressiveness and elegance. It is not a language that can be used by NAE. NAE scripts are written in Python, which is a popular and powerful programming language1.
質問 # 28
Your manufacturing client is deploying two hundred wireless IP cameras and fifty headless scanners in their warehouse. These new devices do not support 802.1X authentication.
How can HPE Aruba enhance security for these new IP cameras in this environment?
- A. MPSK Local will allow the cameras to share a rey and the scanners to share a different
- B. Aruba ClearPass performs the 802.1X authentication and installs a certificate.
- C. MPSK provides for each device in the WLAN to have its own unique pre-shared Key.
- D. Use MPSK Local to automatically provide unique pre-shared Keys for devices.
正解：C
解説：
The best option to enhance security for the new IP cameras and scanners in this environment is C. MPSK provides for each device in the WLAN to have its own unique pre-shared key.
MPSK stands for Multi Pre-Shared Key, and it is a feature that allows different devices to connect to the same SSID with different pre-shared keys. This improves the security and scalability of the network, as each device can have its own key and role without requiring 802.1X authentication or an external policy engine. MPSK can be configured either locally on the AP or centrally on Aruba Central12.
The other options are incorrect because:
A) MPSK Local is a feature that allows the user to configure 24 PSKs per SSID locally on the device. These local PSKs would serve as an extension of the base MPSK functionality. However, MPSK Local is not suitable for this scenario, as it can only support up to 24 devices per SSID, while the client has 250 devices1.
B) Aruba ClearPass is a network access control solution that can perform 802.1X authentication and install certificates for devices. However, this option is not feasible for this scenario, as the new IP cameras and scanners do not support 802.1X authentication3.
D) MPSK Local will not allow the cameras to share a key and the scanners to share a different key. MPSK Local will assign a different key to each device, regardless of their type. Moreover, MPSK Local can only support up to 24 devices per SSID, while the client has 250 devices1.
質問 # 29
A customer has a large number of food-producing machines
* All machines are connected via Aruba CX6200 switches in VLANs 100.110. and 120
* Several external technicians are maintaining this special equipment
What are the correct commands to ensure that no rogue DHCP server will impact the network?
- A.
- B.
- C.
- D.
正解：C
解説：
Explanation
configures DHCP snooping on the switch and enables it for VLANs 100, 110, and 120. It also specifies the IP address of the authorized DHCP server and sets the ports connected to the server as trusted. This prevents any unauthorized DHCP server from providing invalid configuration data to the clients on those VLANs. Option B also enables DHCP option-82, which adds information about the switch port and VLAN to the DHCP packets, allowing for more granular control and logging of DHCP transactions.
質問 # 30
How do you allow a new VLAN 100 between VSX pair inter-switch-link 256 for port 1/45 and 2/45?
- A. vlan trunk add 100 in MLAG256
- B. vlan trunk allowed 100 in LAG256
- C. vlan trunk allowed 100 for ports 1/45 and 1/46
- D. vlan trunk add 100 in LAG256
正解：B
解説：
To allow a new VLAN 100 between VSX pair inter-switch-link 256 for port 1/45 and 2/45, you need to use the command vlan trunk allowed 100 in LAG256. This will add VLAN 100 to the list of allowed VLANs on the trunk port LAG256, which is part of the inter-switch-link between VSX peers. The other options are incorrect because they either do not use the correct command or do not specify the correct port or VLAN.

質問 # 31
Which Aruba AP mode is sending captured RF data to Aruba Central for waterfall plot?
- A. Spectrum Monitor
- B. Air Monitor
- C. Hybrid Mode
- D. Dual Mode
正解：A
解説：
Spectrum Monitor is an Aruba AP mode that is sending captured RF data to Aruba Central for waterfall plot. Spectrum Monitor is a mode that allows an AP to scan all channels in both 2.4 GHz and 5 GHz bands and collect information about the RF environment, such as interference sources, noise floor, channel utilization, etc. The AP then sends this data to Aruba Central, which is a cloud-based network management platform that can display the data in various formats, including waterfall plot. Waterfall plot is a graphical representation of the RF spectrum over time, showing the frequency, amplitude, and duration of RF signals. The other options are incorrect because they are either not AP modes or not sending RF data to Aruba Central.

- A. Create a new OSPF area, and attach VRF name.
- B. Create a new OSPF process ID with vrf name.
- C. Attach OSPF process ID in the VRF configuration.
- D. Attach a new OSFP process ID with a custom routing table
正解：B
解説：
Explanation
To create a new OSPF configuration for a separate routing table, you need to create a new OSPF process ID with vrf name. This will create a new OSPF instance that is associated with the specified VRF and its routing table. The other options are incorrect because they either do not create a new OSPF instance or do not associate it with a VRF. References:

質問 # 33
Which statements are true about VSX LAG? (Select two.)
- A. LAG traffic is passed over VSX ISL links only while upgrading firmware on the switch pair
- B. Outgoing traffic is preferentially switched to local members of the LAG.
- C. Up to 255 VSX lags can be configured on all 83xx and 84xx model switches.
- D. The total number of configured links may not exceed 8 for the pair or 4 per switch
- E. Outgoing traffic is switched to a port based on a hashing algorithm which may be either switch in the pair
正解：B、D
解説：
Explanation
The correct answers are A and D.
According to the web search results, VSX LAG is a feature that allows multiple PSKs to be used on a single SSID, providing device-specific or group-specific passphrases for enhanced security and deployment flexibility for headless IoT devices1. VSX LAGs span both aggregation switches and appear as one device to partner downstream or upstream devices or both when forming a LAG with the VSX pair2.
One of the statements that is true about VSX LAG is that the total number of configured links may not exceed
8 for the pair or 4 per switch1. This means that a VSX LAG across a downstream switch can have at most a total of eight member links, and a switch can have a maximum of four member links. When creating a VSX LAG, it is recommended to select an equal number of member links in each segment for load balancing1.
Another statement that is true about VSX LAG is that outgoing traffic is preferentially switched to local members of the LAG2. This means that when active forwarding and active gateway are enabled, north-south and south-north traffic bypasses the ISL link and uses the local ports on the switch. This optimizes the traffic path and reduces the load on the ISL link2.
The other statements are false or not relevant for VSX LAG. Outgoing traffic is not switched to a port based on a hashing algorithm, which may be either switch in the pair. This is a characteristic of MLAG (Multi-Chassis Link Aggregation), which is a different feature from VSX LAG. LAG traffic is not passed over VSX ISL links only while upgrading firmware on the switch pair. This is a scenario that may occur when performing hitless upgrades, which is a feature that allows software updates without impacting network availability. The number of VSX lags that can be configured on all 83xx and 84xx model switches is not 255, but depends on the switch model and firmware version. For example, the AOS-CX 10.04 supports up to 64 VSX lags for 8320 switches and up to 128 VSX lags for 8325 and 8400 switches.

質問 # 40
What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2?
(Select two.)
- A. The Key Management service receives from AirMatch a list of all AP2's neighbors
- B. The Key Management service then generates R1 keys for AP2's neighbors.
- C. AP1 will cache the client's information and send it to the Key Management service
- D. The Key Management service receives a list of all AP1 s neighbors from AirMatch.
- E. A client associates and authenticates with the AP2 after roaming from AP1
正解：B、C
解説：
Explanation
The correct steps that are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2 are A and D.
A: AP1 will cache the client's information and send it to the Key Management service. This is true because when a client associates and authenticates with AP1, AP1 will generate a pairwise master key (PMK) for the client and store it in its cache. AP1 will also send the PMK and other client information, such as MAC address, VLAN, and SSID, to the Key Management service, which is a centralized service that runs on Aruba Mobility Controllers (MCs) or Mobility Master (MM) devices1. The Key Management service will use this information to facilitate fast roaming for the client.
D: The Key Management service then generates R1 keys for AP2's neighbors. This is true because when the Key Management service receives the client information from AP1, it will use the PMK to derive R0 and R1 keys for the client. R0 keys are used to generate R1 keys, which are used to generate pairwise transient keys (PTKs) for encryption. The Key Management service will distribute the R1 keys to AP2 and its neighboring APs, which are determined by AirMatch based on RF proximity2. This way, when the client roams to AP2 or any of its neighbors, it can skip the 802.1X authentication and use the R1 key to quickly generate a PTK with the new AP3.
B: The Key Management service receives from AirMatch a list of all AP2's neighbors. This is false because the Key Management service does not receive this information from AirMatch directly. AirMatch is a feature that runs on MCs or MM devices and optimizes the RF performance of Aruba devices by using machine learning algorithms. AirMatch periodically sends neighbor reports to all APs, which contain information about their nearby APs based on signal strength and interference. The APs then send these reports to the Key Management service, which uses them to determine which APs should receive R1 keys for a given client2.
C: The Key Management service receives a list of all AP1 s neighbors from AirMatch. This is false for the same reason as B. The Key Management service does not receive this information from AirMatch directly, but from the APs that send their neighbor reports.
E: A client associates and authenticates with the AP2 after roaming from AP1. This is false because a client does not need to authenticate with AP2 after roaming from AP1 if it has already authenticated with AP1 and received R1 keys from the Key Management service. The client only needs to associate with AP2 and perform a four-way handshake using the R1 key to generate a PTK for encryption3. This is called fast roaming or
802.11r roaming, and it reduces the latency and disruption caused by full authentication.1: ArubaOS 8.7 User Guide 2: ArubaOS 8.7 User Guide 3: ArubaOS 8.7 User Guide : ArubaOS 8.7 User Guide
質問 # 41
your customer has asked you to assign a switch management role for a new user The customer requires the user role to View switch configuration information and have access to the PUT and POST meth0ds for REST API.
Which default AOS-CX user role meets these requirements?
- A. administrators
- B. auditors
- C. helpdesk
- D. sysops
正解：D
解説：
The correct answer is C. sysops.
The sysops user role is a predefined role that allows users to view switch configuration information and have access to the PUT and POST methods for REST API. The sysops user role can also use the PATCH and DELETE methods for REST API, but not for all resources. The sysops user role is suitable for users who need to perform system operations on the switch, such as backup, restore, upgrade, or reboot.
According to the AOS-CX REST API Reference basics1, one of the predefined user roles is:
sysops: Users with this role can view switch configuration information and have access to the PUT and POST methods for REST API. They can also use the PATCH and DELETE methods for REST API, but not for all resources. Users with this role can perform system operations on the switch, such as backup, restore, upgrade, or reboot.
The other options are incorrect because:
A) administrators: Users with this role have full access to all switch configuration information and all REST API methods. This role is more than what the customer requires.
B) auditors: Users with this role can only view switch configuration information and have access to the GET method for REST API. They cannot use the PUT and POST methods for REST API.
D) helpdesk: Users with this role can view switch configuration information and have access to the GET method for REST API. They can also use the PATCH method for REST API, but only for a limited set of resources. They cannot use the PUT and POST methods for REST API.
質問 # 42
By default, Best Effort is higher priority than which priority traffic type?
- A. Internet Control
- B. Background
- C. Network Control
- D. All queues
正解：B
解説：
Explanation
This is because Best Effort traffic is all other kinds of non-detrimental traffic that are not sensitive to Quality of Service metrics (jitter, packet loss, latency). A typical example would be peer-to-peer and email applications2. Background traffic is a type of traffic that is used for system maintenance or backup purposes and does not affect the performance or availability of the network3.
Therefore, Best Effort traffic has a higher priority than Background traffic in terms of network resources allocation and management.

質問 # 43
What is an OSPF transit network?
- A. a network on which a router discovers at least one neighbor
- B. a network that connects to a different routing protocol
- C. a network that uses tunnels to connect two areas
- D. a special network that connects two different areas
正解：D
解説：
Explanation
OSPF is a link-state routing protocol that divides a network into areas. An area is a logical grouping of routers that share the same link-state information. Area 0 is the backbone area that connects all other areas. A transit network is a special network that connects two different areas. A transit network must belong to Area 0 and have at least two OSPF routers attached to it. A transit network allows traffic from one area to pass through another area without changing the area ID.

Your Director of Security asks you to assign AOS-CX switch management roles to new employees based on their specific job requirements After the configuration was complete, it was noted that a user assigned with the administrators role did not have the appropriate level of access on the switch.
The user was not limited to viewing nonsensitive configuration information and a level of 1 was not assigned to their role Which default management role should have been assigned for the user?
- A. config
- B. helpdesk
- C. sysadmin
- D. operators
正解：D
解説：
The default management role that should have been assigned for the user is B. operators.
The operators user role is a predefined role that allows users to view nonsensitive configuration information on the switch, such as interfaces, VLANs, routing protocols, statistics, and more. The operators user role has a privilege level of 1, which is the lowest level of access on the switch1.
The administrators user role is a predefined role that has full access to all switch configuration information and all REST API methods. This role is more than what the Director of Security requires1.

- B. Configure the linkup delay timer to 120 seconds, which will allow the right amount of time for the initial phase to sync
- C. Configure the linkup delay timer to include LAGs 101 and 102, which will allow time for routing adjacencies lo form and to learn upstream routes
- D. Configure the linkup delay timer to exclude LAGS 101 and 102, which will allow time for routing adjacencies to form and to learn upstream routes
正解：C
解説：
The reason is that the linkup delay timer is a feature that delays bringing downstream VSX links up, following a VSX device reboot or an ISL flap. The linkup delay timer has two phases: initial synchronization phase and link-up delay phase.
The initial synchronization phase is the download phase where the rebooted node learns all the LACP+MAC+ARP+STP database entries from its VSX peer through ISLP. The initial synchronization timer, which is not configurable, is the required time to download the database information from the peer.
The link-up delay phase is the duration for installing the downloaded entries to the ASIC, establishing router adjacencies with core nodes and learning upstream routes. The link-up delay timer default value is 180 seconds. Depending on the network size, ARP/routing tables size, you might be required to set the timer to a higher value (maximum 600 seconds).
When both VSX devices reboot, the link-up delay timer is not used.
Therefore, by configuring the linkup delay timer to include LAGs 101 and 102, which are part of the same VSX device as LAG 201, you can ensure that both devices have enough time to synchronize their databases and form routing adjacencies before bringing down their downstream links.

You are configuring an SVI on an Aruba CX switch that needs to have the following characteristics:
* VLANID = 25
. IPv4 address 10 105 43 1 with mask 255 255 255.0
* IPv6 address fd00:5708::f02d:4df6 with a 64 bit prefix length
* member of VRF eng
* VRF eng and VLAN 25 have not yet been created
Which command lists will satisfy the requirements with the least number of commands?
- A.
- B.
- C.
- D.
正解：B
解説：
Explanation
The other options either use more commands or do not create the VRF or the VLAN.
Option C uses the following commands:
* vrf eng: This command creates a VRF named eng and enters the VRF configuration mode1.
* vlan 25: This command creates a VLAN with ID 25 and enters the VLAN configuration mode2.
* interface vlan 25: This command creates an SVI on VLAN 25 and enters the interface configuration mode3.
* ip address 10.105.43.1/24 ipv6 address fd00:5780::102d:4df6/64 vrf attach eng: This command assigns an IPv4 address of 10.105.43.1 with a subnet mask of 255.255.255.0 and an IPv6 address of fd00:5780::102d:4df6 with a prefix length of 64 to the SVI, and attaches it to the VRF eng.

A system engineer needs to preconfigure several Aruba CX 6300 switches that will be sent to a remote office An untrained local field technician will do the rollout of the switches and the mounting of several AP-515s and AP-575S. Cables running to theAPs are not labeled.
The VLANs are already preconfigured to VLAN 100 (mgmt), VLAN 200 (clients), and VLAN 300 (guests) What is the correct configuration to ensure that APs will work properly?
- A.
- B.
- C.
- D.
正解：D
解説：
Option C is the correct configuration to ensure that APs will work properly. It uses the ap command to configure a port profile for APs with VLAN 100 as the native VLAN and VLAN 200 and 300 as tagged VLANs. It also enables LLDP on the ports to discover the APs and assign them to the port profile automatically. The other options are incorrect because they either do not use the ap command, do not enable LLDP, or do not configure the VLANs correctly.
