質問 # 28
A new network design is being considered to minimize client latency in a high-density environment. The design needs to do this by eliminating contention overhead by dedicating subcarriers to clients.
Which technology is the best match for this use case?

• A. Channel Bonding
• B. MU-MIMO
• C. QWMM
• D. OFDMA

正解：D

解説：
OFDMA (Orthogonal Frequency Division Multiple Access) is a technology that can minimize client latency in a high-density environment by eliminating contention overhead by dedicating subcarriers to clients. OFDMA allows multiple clients to transmit simultaneously on different subcarriers within the same channel, reducing contention and increasing efficiency. MU-MIMO (Multi-User Multiple Input Multiple Output) is a technology that allows multiple clients to transmit simultaneously on different spatial streams within the same channel, but it does not eliminate contention overhead. QWMM (Quality of Service Wireless Multimedia) is a technology that prioritizes traffic based on four access categories, but it does not eliminate contention overhead. Channel Bonding is a technology that combines two adjacent channels into one wider channel, increasing bandwidth but not eliminating contention overhead.

質問 # 29
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 receives a list of all AP1 s neighbors from AirMatch.
• C. The Key Management service then generates R1 keys for AP2's neighbors.
• D. AP1 will cache the client's information and send it to the Key Management service
• E. A client associates and authenticates with the AP2 after roaming from AP1

正解：B、C

解説：
Explanation
Key Management is a service that runs on Aruba Mobility Controllers (MCs) or Mobility Master (MM) to optimize roaming performance for wireless clients. Key Management works with AirMatch, a service that optimizes radio resource management for Aruba APs, to pre-generate and distribute R1 keys for neighboring APs before a client roams. When a wireless device is roaming from AP1 to AP2, the following steps are part of the Key Management workflow3:
* The client associates and authenticates with AP1 using 802.1X or PSK methods.
* The Key Management service caches the client's information and generates an R0 key for the client.
* The Key Management service receives a list of all AP1's neighbors from AirMatch.
* The Key Management service then generates R1 keys for AP1's neighbors using the R0 key and sends them to the corresponding APs.
* When the client roams to AP2, one of AP1's neighbors, it performs an 802.11r fast transition using the pre-generated R1 key without needing to re-authenticate.

質問 # 30
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. Aruba ClearPass performs the 802.1X authentication and installs a certificate.
• B. MPSK Local will allow the cameras to share a rey and the scanners to share a different
• C. Use MPSK Local to automatically provide unique pre-shared Keys for devices.
• D. MPSK provides for each device in the WLAN to have its own unique pre-shared Key.

正解：D

解説：
Explanation
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.

* 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.

質問 # 32
Which component is used by the Aruba Network Analytics Engine (NAE)?

• A. Current State Database
• B. Lisp-based agents
• C. Ruby-based scripts
• D. JSON-based scripts

正解：D

解説：
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 # 33
You are deploying a bonded 40 MHz wide channel What is the difference in the noise floor perceived by a client using this bonded channel as compared to an unbonded 20MHz wide channel?

• A. 4dB
• B. 2dB
• C. 3dB
• D. 8dB

正解：C

解説：
The difference in the noise floor perceived by a client using a bonded 40 MHz wide channel as compared to an unbonded 20 MHz wide channel is 3 dB. The noise floor is the level of background noise in a given frequency band. When two adjacent channels are bonded, the noise floor increases by 3 dB because the bandwidth is doubled and more noise is captured. The other options are incorrect because they do not reflect the correct relationship between bandwidth and noise floor.

質問 # 34
Review the exhibit.

You are troubleshooting an issue with a 10 102.39 0/24 subnet which is also VLAN 1000 used Tor wireless clients on a pair of Aruba CX 8360 switches The subnet SVI is configured on the 8360 pair, and the DHCP server is a Microsoft Windows Server 2022 Standard with an IP address of 10 200 1.100. The 10.102.250.0/24 subnet is used for switch management.
A large number of DHCP requests are failing You are observing sporadic DHCP behavior across clients attached to the CX 6100 switch.
Which action may help fix the issue?

• A.
• B.
• C.
• D.

正解：C

解説：
Explanation
Option B is the correct action that may help fix the issue of sporadic DHCP behavior across clients attached to the CX 6100 switch. Option B enables DHCP relay on VLAN 1000 interface on Core-1 switch, which allows DHCP requests from clients in VLAN 1000 to be forwarded to the DHCP server in a different subnet (10.200.1.100). Without DHCP relay, clients in VLAN 1000 cannot obtain IP addresses from the DHCP server because they are in different broadcast domains. The other options are incorrect because they either do not enable DHCP relay or do not configure it correctly. References:

質問 # 36
Your Aruba CX 6300 VSF stack has OSPF adjacency over SVI 10 with LAG 1 to a neighboring device The following configuration was created on the switch:

• A.
• B.
• C.
• D.

正解：C

解説：
OSPF (Open Shortest Path First) is a routing protocol that uses link-state information to calculate the best path to each destination in the network. OSPF establishes adjacencies with neighboring routers to exchange routing information and maintain a consistent view of the network topology1.
To establish an OSPF adjacency, the routers need to have some common parameters, such as the area ID, the network type, the hello interval, the dead interval, and the authentication method2. The routers also need to have a matching subnet mask on the interface that connects them3.
In this case, the Aruba CX 6300 VSF stack has an SVI (Switched Virtual Interface) on VLAN 10 with an IP address of 10.1.1.1/24 and a LAG (Link Aggregation Group) on port 1/1/1 and port 2/1/1 that connects to a neighboring device. The SVI is configured with OSPF area 0 and network type broadcast. The LAG is configured with OSPF passive mode, which means that it will not send or receive OSPF hello packets.
The neighboring device has an interface with an IP address of 10.1.1.2/24 and a LAG on port 1/0/1 and port 2/0/1 that connects to the Aruba CX 6300 VSF stack. The interface is configured with OSPF area 0 and network type broadcast.
Since the Aruba CX 6300 VSF stack and the neighboring device have the same area ID, network type, subnet mask, and default hello and dead intervals on their interfaces, they will be able to establish an OSPF adjacency over SVI 10 with LAG 1. The OSPF passive mode on the LAG will not affect the adjacency, because it only applies to the LAG interface, not the SVI interface.

質問 # 37
A customer is using Aruba Cloud Guest, but visitors keep complaining that the captive portal page keeps coming up after devices go to sleep Which solution should be enabled to deal with this issue?

• A. MAC Caching under the user-role
• B. Wireless Caching under the splash page
• C. MAC Caching under the splash page
• D. MAC Caching under the WLAN

正解：D

解説：
Explanation
This is the correct solution to deal with the issue where visitors keep complaining that the captive portal page keeps coming up after devices go to sleep. MAC Caching is a feature that allows an Aruba Access Point to bypass authentication for devices that have already been authenticated by a captive portal. MAC Caching can be enabled under the WLAN settings in Aruba Cloud Guest by selecting the MAC Caching checkbox and specifying the MAC Caching duration. The other options are incorrect because they either do not exist or do not apply to Aruba Cloud Guest. References:
https://www.arubanetworks.com/techdocs/CloudGuest/Content/Topics/MAC_Caching.htm

質問 # 38
The administrator notices that wired guest users that have exceeded their bandwidth limit are not being disconnected Access Tracker in ClearPass indicates a disconnect CoA message is being sent to the AOS-CX switch.
An administrator has performed the following configuration

What is the most likely cause of this issue?

• A. There is a mismatch between the RADIUS secret on the switch and CPPM.
• B. There is a time difference between the switch and the ClearPass Policy Manager
• C. Change of Authorization has not been globally enabled on the switch
• D. The SSL certificate for CPPM has not been added as a trust point on the switch

正解：C

解説：
Explanation
Change of Authorization (CoA) is a feature that allows ClearPass Policy Manager (CPPM) to send messages to network devices such as switches to change the authorization state of a user session. CoA requires that both CPPM and the network device support this feature and have it enabled. For AOS-CX switches, CoA must be globally enabled using the command radius-server coa enable. If CoA is not enabled on the switch, the disconnect CoA message from CPPM will be ignored and the user session will not be terminated. References:

質問 # 39
Refer to the image.

Your customer is complaining of weak Wi-Fi coverage in their office. They mention that the office on the other side of the hall has much better signal What is the likely cause of this issue7

• A. The AP is using a directional antenna.
• B. The AP is configured in Mesh mode
• C. The AP is an outdoor access point.
• D. The AP is a remote access point.

正解：A

解説：
The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna. A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario.

質問 # 40
What is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports?

• A. Manually enable Enhanced Security Mode from a console session.
• B. Disable all management services on the default VRF.
• C. Create a dedicated management VRF, and assign the management port to it.
• D. Implement a control plane ACL to limit access to approved IPs and/or subnets

正解：C

解説：
Explanation
This is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports. A dedicated management port is a physical port that is used exclusively for out-of-band management access to the switch. A dedicated management VRF is a virtual routing and forwarding instance that isolates the management traffic from other traffic on the switch. By creating a dedicated management VRF and assigning the management port to it, the administrator can enhance the security and performance of the management access to the switch. The other options are incorrect because they either do not apply to switches with dedicated management ports or do not follow Aruba-recommended best practices.

質問 # 41
A network engineer recently identified that a wired device connected to a CX Switch is misbehaving on the network To address this issue, a new ClearPass policy has been put in place to prevent this device from connecting to the network again.
Which steps need to be implemented to allow ClearPass to perform a CoA and change the access for this wired device? (Select two.)

• A. Configure dynamic authorization on the switchport
• B. Bounce the switchport
• C. Use Dynamic Segmentation.
• D. Configure dynamic authorization on the switch.
• E. Confirm that NTP is configured on the switch and ClearPass

正解：B、D

解説：
CoA (Change of Authorization) is a feature that allows ClearPass to dynamically change the authorization and access privileges of a device after it has been authenticated1. CoA uses RADIUS messages to communicate with the network device and instruct it to perform an action, such as reauthenticating the device, applying a new VLAN or user role, or disconnecting the device2.
To enable CoA on a CX switch, the network engineer needs to configure dynamic authorization on the switch, which is a global command that allows the switch to accept RADIUS messages from ClearPass and execute the requested actions3. The network engineer also needs to specify the IP address and shared secret of ClearPass as a dynamic authorization client on the switch3.
To trigger CoA for a specific wired device, the network engineer needs to bounce the switchport, which is an action that temporarily disables and re-enables the port where the device is connected. This forces the device to reauthenticate and receive the new policy from ClearPass. Bouncing the switchport can be done manually by using the interface shutdown and no shutdown commands, or automatically by using ClearPass as a CoA server and sending a RADIUS message with the Port-Bounce-Host AVP (Attribute-Value Pair).

質問 # 42
What is a primary benefit of BSS coloring?

• A. BSS color tags improve performance by allowing clients on the same channel to share airtime.
• B. BSS color tags are applied to client devices and can reduce the threshold for interference
• C. BSS color tags improve security by identifying rogue APs and removing them from the network.
• D. BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference

正解：B

解説：
Explanation
This is the correct definition of BSS coloring and its primary benefit. BSS coloring is a mechanism that assigns a color code to each BSS (Basic Service Set), which consists of an AP and its associated clients. The color code is added to the PHY header of each frame transmitted by the AP or the client. BSS coloring helps reduce co-channel interference by allowing devices to differentiate between frames from their own BSS and frames from neighboring BSSs that use the same channel. Devices can then adjust their threshold for interference based on the color code and decide whether to transmit or defer based on the channel status. The other options are incorrect because they either describe different mechanisms or benefits of BSS coloring or use incorrect terms. References:

質問 # 43
A company recently deployed new Aruba Access Points at different branch offices Wireless 802.1X authentication will be against a RADIUS server in the cloud. The security team is concerned that the traffic between the AP and the RADIUS server will be exposed.
What is the appropriate solution for this scenario?

• A. Enable EAP-TLS on all wireless devices
• B. Enable EAP-TTLS on all wireless devices.
• C. Configure RadSec on the AP and the RADIUS server
• D. Configure RadSec on the AP and Aruba Central.

正解：C

解説：
This is the appropriate solution for this scenario where wireless 802.1X authentication will be against a RADIUS server in the cloud and the security team is concerned that the traffic between the AP and the RADIUS server will be exposed. RadSec, also known as RADIUS over TLS, is a protocol that provides encryption and authentication for RADIUS traffic over TCP and TLS. RadSec can be configured on both the AP and the RADIUS server to establish a secure tunnel for exchanging RADIUS packets. The other options are incorrect because they either do not provide encryption or authentication for RADIUS traffic or do not involve RadSec. Reference: https://www.securew2.com/blog/what-is-radsec/ https://www.cloudradius.com/radsec-vs-radius/

質問 # 44
Refer to Exhibit:

A company has deployed 200 AP-635 access points. To take advantage of the 6 GHz band, the administrator has attempted to configure a new WPA3-OWE SSID in Central but is not working as expected.
What would be the correct action to fix the issue?

• A. Change the SSID to WPA3-Enterprise (CCM).
• B. Change the SSID to WPA3-Enterprise (CNSA).
• C. Change the SSID to WPA3-Enhanced Open.
• D. Change the SSID to WPA3-Personal.

正解：C

解説：
The correct action to fix the issue is C. Change the SSID to WPA3-Enhanced Open.
WPA3-OWE is not a valid SSID type in Central. OWE stands for Opportunistic Wireless Encryption, and it is a feature that provides encryption for open networks without requiring authentication. OWE is also known as Enhanced Open, and it is one of the options for WPA3 SSIDs in Central1.
According to the Aruba document Configuring WLAN Settings for an SSID Profile, one of the steps to configure a WPA3 SSID is:
Select the Security Level from the drop-down list. The following options are available:
WPA3-Personal: This option uses Simultaneous Authentication of Equals (SAE) to provide stronger password-based authentication and key exchange than WPA2-Personal.
WPA3-Enterprise: This option uses 192-bit cryptographic strength for authentication and encryption, as defined by the Commercial National Security Algorithm (CNSA) suite.
WPA3-Enterprise (CCM): This option uses 128-bit cryptographic strength for authentication and encryption, as defined by the Counter with CBC-MAC (CCM) mode.
WPA3-Enhanced Open: This option uses Opportunistic Wireless Encryption (OWE) to provide encryption for open networks without requiring authentication.
The other options are incorrect because:
A) WPA3-Enterprise (CNSA) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company's use case.
B) WPA3-Personal is a valid SSID type, but it requires a passphrase to join the network, which may not be suitable for the company's use case.
D) WPA3-Enterprise (CCM) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company's use case.

質問 # 45
Which component is used by the Aruba Network Analytics Engine (NAE)?

• A. Current State Database
• B. Lisp-based agents
• C. Ruby-based scripts
• D. JSON-based scripts

正解：D

解説：
Explanation
JSON-based scripts are the components used by the Aruba Network Analytics Engine (NAE). NAE is a feature that provides network monitoring and troubleshooting capabilities using JSON-based scripts called agents. Agents collect data from various sources, such as switch CLI commands, SNMP queries, REST APIs, etc., and analyze them using predefined rules and thresholds. Agents can also generate alerts, notifications, actions, or reports based on the analysis results. References:

質問 # 46
You are configuring Policy Based Routing (PBR) for a subnet that will be used to test a new default route for your network Traffic originating from 10.2.250.0/24 should use a new default route to 10.1.1.253. Other non-default routes for this subnet should not be affected by this change.
What are two parts of the solution for these requirements? (Select two.)

• A.
• B.
• C.
• D.
• E.

正解：B、E

解説：
Two parts of the solution for these requirements are Option C and Option E.
Option C is a part of the solution because it defines a policy-based routing action list named route_test, which specifies the next hop IP address as 10.1.1.253 for the matching traffic. This is the new default route that the user wants to use for the subnet 10.2.250.0/24. The interface null parameter indicates that the traffic will be routed to the next hop without using a specific interface1.
Option E is a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 250, which has an IP address of 10.2.250.1/24. This is the subnet that the user wants to test the new default route for. The apply policy command enables policy-based routing on the interface and associates it with the action list2.
Option A is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify the next hop IP address as 10.1.1.253, which is the new default route that the user wants to use. Instead, it specifies a next hop IP address of 10.1.1.254, which is different from the requirement.
Option B is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify any next hop IP address at all, which is necessary for policy-based routing to work. Instead, it specifies an interface null parameter without any IP address, which is invalid.
Option D is not a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 200, which has an IP address of 10.2.200.1/24. This is not the subnet that the user wants to test the new default route for, but a different subnet that should not be affected by this change.

質問 # 47
The customer needs a network hardware refresh to replace an aging Aruba 5406R core switch pair using spanning tree configuration with Aruba CX 8360-32YC switches What is the benefit of VSX clustering with the new solution?

• A. dual control plane provides better resiliency
• B. stacked data-plane
• C. faster MSTP converge processing
• D. dual Aruba AP LAN port connectivity for PoE redundancy

正解：A

解説：
Explanation
VSX clustering is a feature that allows two Aruba CX switches to operate as a single logical device, providing high availability, scalability, and simplified management. VSX clustering has several benefits over spanning tree configuration, such as:
* Dual control plane provides better resiliency. Unlike stacking, where switches share a single control plane, VSX switches have independent control planes that synchronize their states over an inter-switch link (ISL). This means that if one switch fails or reboots, the other switch can continue to operate without affecting traffic flows or network services.
* Active-active forwarding provides better performance. Unlike spanning tree, where some links are blocked to prevent loops, VSX switches use all available links for forwarding traffic, providing load balancing and increased bandwidth utilization.
* Multichassis LAG provides better redundancy. Unlike single-chassis LAG, where all member ports belong to one switch, VSX switches can form multichassis LAGs with downstream or upstream devices, where member ports are distributed across both switches. This provides link redundancy and seamless failover in case of switch or port failure.

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：C

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.

Your customer has four (4) Aruba 7200 Series Gateways and two (2) 7000 Series Gateways. The customer wants to form a cluster with these Gateways. What design consideration would prevent you from using all of those Gateways?

• A. The AP load should be lowest value of worst-case scenario load.
• B. A combination of 7200 series and 7000 series gateways supports up to 4 nodes
• C. A heterogeneous cluster is not supported in AOS 10.x.
• D. Multiple versions between Gateways in the same cluster profile are not allowed AOS 10.x.

正解：D

解説：
Explanation
The reason is that AOS 10.x does not support clustering gateways with different versions in the same cluster profile. A cluster profile defines the configuration settings for a group of gateways that are managed by Aruba Central.
According to the Aruba documentation2, "You can combine 7200 Series and 7000 Series gateways in the same cluster with a maximum size of four devices with reduced AP client capacity on 7000 Series gateways."
