• Question 32:

  Which statements accurately describe OSPF Graceful Restart (when the restarting router is able to Keep its forwarding tables across the restart)? (Select two.)

  A. The GR helper role is supported on AOX-CX 6100 switches.
  B. VSF Failover and Graceful-Restart require a VSF secondary member in the VSF stack
  C. Bidirectional Forwarding Detection for OSPF and GR are mutually exclusive features.
  D. OSPF Routers listen for Grace-LSAs on each network segment where there is an OSFP adjacency.
  E. You must ensure your VSF stack has a secondary member when acting as a GR helper
  A. The GR helper role is supported on AOX-CX 6100 switches.
  D. OSPF Routers listen for Grace-LSAs on each network segment where there is an OSFP adjacency.

  ---

  Explanation/Reference:

  Graceful Restart (GR) allows a router to continue forwarding packets while it restarts its OSPF process. The GR helper role on AOS-CX switches supports routers during this process. OSPFrouters listen for Grace-LSAs to identify neighbors undergoing a graceful restart, maintaining adjacencies with those routers to allow uninterrupted forwarding.

• Question 33:

  You configured a tunneled SSID with captive portal and a ClearPass Guest Self Registration workflow when testing and launching the self-registration workflow, after successful registration, the login action shows the following error:

  

  What is the best solution to resolve this error?

  A. You need to include the root and intermediate certificates in the captive portal certificate for your access points
  B. You need to De connected to the guest SSiD while testing.
  C. You need to change the Login Address in ClearPass to securelogin arubanetworKs.com
  D. You need to include the root and intermediate certificates in the captive portal certificate for your gateway
  D. You need to include the root and intermediate certificates in the captive portal certificate for your gateway

  ---

  Explanation/Reference:

  Including the root and intermediate certificates in the captive portal certificate for the gateway will resolve the error seen during the login action after successful registration. This is necessary to ensure the SSL/TLS handshake can be completed successfully, as the client browser needs to validate the entire certificate chain.

• Question 34:

  A Windows device attempts to connect to an 802.1X network but it is not receiving the correct role. TEAP has been configured asthe only authentication method in ClearPass.The wireless configuration is correct. Exhibit.

  

  What is me mostlikelycause?

  A. The Windows device needs 10 De configured tor TEAP.
  B. ClearPass requires a second authentication method.
  C. 802.1X is not compatible with TEAP in windows device
  D. Only machine authentication should be configured on the Windows device
  A. The Windows device needs 10 De configured tor TEAP.

  ---

  Explanation/Reference:

  The issue likely stems from the Windows device not being configured to use TEAP (Tunneled Extensible Authentication Protocol) as specified in the ClearPass configuration. TEAP is an EAP method that encapsulates an inner EAP method for secure authentication. The Windows device must have TEAP enabled and correctly configured in its network settings to authenticate successfully on the network using ClearPass.

• Question 35:

  DragDrop

  

  

  You updated your gateway to me most recent firmware However after the firmware was updated, the gateway could no longer connect to HPE Aruba Networking Central. Your corporate ITIL procedures require you to implement your backout plan. You connected a console cable to your gateway and saw the following prompt.

  Cpxload#

  in what order, do you need to execute the following commands to return to the previous firmware version?

  Select and Place:

  

  

  ---

  Explanation/Reference:

  The sequence to return to the previous firmware version after an unsuccessful update would typically be:

  1. hit any key to stop autoboot(This would prevent the system from automatically booting into the current, problematic firmware.)

  2. def_part 1(This command sets the default boot partition, which is likely where the previous working firmware is located.)

  3. bootf(This command would boot from the specified flash partition, which after the second step, would be the previous firmware.)

  4. osinfo(After the system is booted, this command could be used to confirm the firmware version now running on the gateway.)

• Question 36:

  You created a new SSID with the security settings shown in the exhibit.

  

  Some, but not all users complain that client devices are unable to connect to this SS1D. What is the reason for this?

  A. The WPA3 Enterprise GCM-2S6 mode does not support transition mode.
  B. WPA3 Enterprise is not backward compatible with WPA2 Enterprise.
  C. MAC authentication after a failed 802. ix authentication is not possible as the option "MAC Authentication Fall-Through" is disabled.
  D. The primary servers shared key differs from the shared key configured for this server on HPE Aruba Networking Central.
  C. MAC authentication after a failed 802. ix authentication is not possible as the option "MAC Authentication Fall-Through" is disabled.

  ---

  Explanation/Reference:

  If some users are unable to connect to an SSID configured with WPA3-Enterprise GCM-256, and the "MAC Authentication Fall-Through" is disabled, it means that devices which fail 802.1X authentication will not attempt MAC authentication. If these client devices are configured to use MAC authentication as a backup method, they will fail to connect, explaining the issue faced by some users.

• Question 37:

  in a WLAN network with a tunneled SSID. you see the following events in HPE Aruba Networking Central:

  

  The customer asks you to investigate log messages What should you tell them?

  A. This indicates a security issue. The client with a MAC address ending with 37 18;0d Is performing a Denial-of-Service attack on your network. You should track down the client and remove it from the network.
  B. This is normal, expected behavior. No further actions are needed.
  C. This indicates a client WLAN driver issue for the client with a MAC address ending with 37:18 :Od. You should upgrade the client WLAN driver.
  D. There is a roaming issue Enable Fast Roaming 802.11r and OKC to resolve the issue.
  C. This indicates a client WLAN driver issue for the client with a MAC address ending with 37:18 :Od. You should upgrade the client WLAN driver.

  ---

  Explanation/Reference:

  The event log showing PMK (Pairwise Master Key) and OKC (Opportunistic Key Caching) key add/update and delete operations is indicative of normal client behavior in a WLAN environment. These events are part of the standard process for maintaining client session security and do not necessarily indicate any issue.

• Question 38:

  A customer is deploying a new warehouse with AP-634 APs inthe unitedStates with mobile devices that can operate in the 6GHz spectrum All testing and RF analyses were performed during the POC using AP-635 APs In a different location During the deployment, they noticed fewer 6GHz channels were broadcasting in the air.

  Why would the AP-634 deployment have a lesser amount of broadcasting channels?

  A. The AP-634 APs do not have an advanced subscription.
  B. The AP-634 APs cannot broadcast an 6Gnz channels due to regulatory restrictions.
  C. The AP-635 APs received different allowable 6GHz channels from the AFC service versus the AP-634 APs due to the POC running in a different location.
  D. The AP-634 AP's persona was configured in the Central group as Standard Power.
  C. The AP-635 APs received different allowable 6GHz channels from the AFC service versus the AP-634 APs due to the POC running in a different location.

  ---

  Explanation/Reference:

  In the United States, the operation in the 6GHz band for Wi-Fi devices such as the AP-634 and AP-635 is regulated by the Automated Frequency Coordination (AFC) system, which determines the channels that can be used based on the location. Since the Proof of Concept (POC) was conducted in a different location using AP-635 APs, the allowable channels identified by the AFC service for that location would be different than the channels allowed for the actual deployment location of the AP-634 APs. This would result in a different set of broadcasting channels being available for use in the new warehouse deployment.

• Question 39:

  Exhibit.

  

  A university runs its own TV station in the city The IT department deploys a multimedia server so the TV productions can be sent out to the entire campus over the IP network using multicast-based communications in order to improve the bandwidth consumption. PlM sparse Mode and IGMP snooping features are enabled.

  When wireless users join the multicast groups, all users connected to the same WLAN experience poor network performance. However, wired users are not affected in this way While troubleshooting the network administrator saves the packet captures shown in the exhibit and concludes that all users even those not joining the multicast group, receive the same multicast flow at slow speeds.

  Which features should the network administrator enable to fix the problem?

  A. Dynamic Multicast Optimization and Multicast Transmission Optimization
  B. UCC QoS correction and Multicast Transmission Optimization
  C. ARP broadcast conversion into unicast and Multicast Transmission Optimization
  D. Dynamic Multicast Optimization and UCC QoS correction
  A. Dynamic Multicast Optimization and Multicast Transmission Optimization

  ---

  Explanation/Reference:

  Dynamic Multicast Optimization (DMO) and Multicast Transmission Optimization are features that can help address issues with multicast traffic in wireless environments. DMO optimizes the way multicast traffic is transmitted over the air by converting multicast streams into unicast streams to the clients that need them. This reduces unnecessary traffic for clients that have not subscribed to the multicast group and can improve overall network performance. Multicast Transmission Optimization adjusts the transmission rate of multicast frames to ensure they are sent at optimal speeds, addressing the issue of multicast flow being received at slow speeds by all users.

• Question 40:

  A customer is running out of IP addresses in a network segment. What will happen If they add an additional IPsubnet to the same VLAN?

  A. Broadcasts for me two subnets win arrive on all ports in the same VLAN
  B. IGMP will not work in both of the subnets in the same VLAN
  C. This would result in a single SVI using two subinterfaces.
  D. Users can reach each other and establish PTP traffic without passing an L3 point in the same VLAN
  D. Users can reach each other and establish PTP traffic without passing an L3 point in the same VLAN

  ---

  Explanation/Reference:

  Adding an additional IP subnet to the same VLAN means that devices configured with either subnet can communicate at Layer 2 without the need for routing. This is because they are on the same VLAN and thus in the same broadcast domain. However, to communicate between subnets, an L3 device or inter-VLAN routing would be required.
