HP HPE7-A07 Online Questions & Answers

• Question 51:

  You are deploying a new AOS 10 mobility gateway cluster. Due to customer requirements, the gateways must be configured with static IP addresses and are restricted from communicating using port 443 to any URLs except tor "central arubanetworks.com

  How would you onboard these gateways successfully into HPE Aruba Networking Central?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

  ---

  Explanation/Reference:

  Option A includes all necessary steps for a full setup of an AOS 10 mobility gateway cluster, including setting the system name, switch role, ACP FQDN address, uplink port information, IP address and default gateway, DNS IP address, controller country code, timezone and clock, andadmin password. Since the gateways must have static IP addresses and can only communicate on port 443 for a specific URL, this configuration would need to allow for static IP configuration and restrict communication to the required URL.

• Question 52:

  Refer to the CLI output below:

  

  What statement about the output above is correct?

  A. The port-access role was configured with gateway-role visitor
  B. The secondary tunnel endpoint IP is 10.10-10.151.
  C. The client authenticated using dot1x.
  D. The UBT zone was configured to use a user-defined VRF
  B. The secondary tunnel endpoint IP is 10.10-10.151.

  ---

  Explanation/Reference:

  The CLI output indicates a tunnel creation process, where "SW hw tun created" refers to the switch hardware tunnel being created. The line mentioning "BYP-10.10.10.101 -> SW hw tun created to 10.10.10.151 tunnel 15." implies that a tunnel was established to the secondary tunnel endpoint with the IP address 10.10.10.151. This is a common configuration for User-Based Tunneling (UBT) setups where traffic is tunneled to a specific endpoint.

• Question 53:

  Based on best practices if an SSID is configured Tor a primary and secondary gateway cluster with cluster preemption enabled, which will decide if the APs move to the secondary gateway cluster if all of the nodes in the primary gateway cluster are down?

  A. tunnel orchestrator for LAN tunnel service in HPE Aruba Networking Central
  B. every AP individually
  C. cluster leader in the primary gateway cluster
  D. cluster leader in the secondary gateway cluster
  B. every AP individually

  ---

  Explanation/Reference:

  In an Aruba network, if an SSID is configured for a primary and secondary gateway cluster with cluster preemption enabled, each AP individually will decide to move to the secondary gateway cluster if all of the nodes in the primary gateway cluster are down. This decentralized decision-making process enhances network resilience and ensures uninterrupted service for clients connected to the APs.

• Question 54:

  A customer has interfering devices that are seen over the air. They contact you and ask you to configure RAPIDS to help identify interfering and rogue APs. HPE Aruba Networking Central identifies a rogue AP and displays the connected switch port.

  How can HPE Aruba Networking Central identify which switch port the AP is connected to?

  A. device profiting on the switch
  B. from the AP MAC address table
  C. from the switch LLDP neighbors table
  D. from the switch MAC address table
  D. from the switch MAC address table

  ---

  Explanation/Reference:

  HPE Aruba Networking Central can identify which switch port a rogue AP is connected to by using the switch's MAC address table. The MAC address table contains the associations between MAC addresses and the switch ports to which devices (including APs) are connected. When Aruba Central detects a rogue AP, it can look up the MAC address of the rogue AP in the switch's MAC address table to find the specific switch port it is connected to. This enables network administrators to quickly locate and address the rogue AP issue.

• Question 55:

  Exhibit.

  

  Which statement is true given the following CLI output from a CX 6300?

  A. There are no active fabric clients on the CX switch with RD 172.16.10.1
  B. A wired client with IP address 10.203 1.100 is on a remote CX 6300 in the fabric with loopback IP address 172.21.11.2.
  C. A wired client with IP address 10 203 1 100 has a host route that is not being properly advertised
  D. The overlay loopbacK addresses are advertised in the faerie with 2d-bit subnet masks
  B. A wired client with IP address 10.203 1.100 is on a remote CX 6300 in the fabric with loopback IP address 172.21.11.2.

  ---

  Explanation/Reference:

  The CLI output provided shows routing information from a CX 6300 switch. The output under "VRF: default" shows various IP routes, including a route for 10.203.1.100/32 with a next hop of 172.21.11.2. This indicates that the route to the client with IP address 10.203.1.100 is known in the network and is reachable via another device in the fabric, which has the loopback IP address 172.21.11.2. Since the route is present in the routing table, it means that the client is known and active within the fabric network.

• Question 56:

  You recently added ClearPass as an authentication server to an HPE Aruba Networking Central group. RADIUS authentication with Local User Roles (LUR) works fine Out the same access points cannot use Downloadable User Roles (DUR). What should he corrected in this configuration to fa the issue with DUR?

  A. Add a new Enforcement Policy of type `'WEBAUTH''on ClearPass and associate it with the matching service on ClearPass
  B. Add the correct IP addresses or IP subnets of the Network Access Devices(NADs) under the "Devices" tabon ClearPass
  C. Replace the AP's expiree digital certificate using the "crypto pki-import pem serverCert" command.
  D. Add the correct values for "CPPM username" and "CPPM Password" m the authentication server configuration on HPEAruba Networking Central
  B. Add the correct IP addresses or IP subnets of the Network Access Devices(NADs) under the "Devices" tabon ClearPass

  ---

  Explanation/Reference:

  For Downloadable User Roles (DUR) to function correctly with ClearPass, the Network Access Devices (NADs) need to be correctly defined in ClearPass under the "Devices" tab. This ensures that ClearPass can identify and communicate with the NADs to deliver the appropriate user roles. If the NADs are not correctly defined, ClearPass will not be able to provide the DURs to the access points for enforcement. This is a common configuration step that is required to integrate ClearPass with network devices for advanced role-based access control.

• Question 57:

  Which statement is true given the following CLIoutput from a CX 6300?

  

  A. The underlay loopback addresses are in the 172 21 11 x range.
  B. There are two anycast addresses m me overlay fabric.
  C. Duplicate MAC addresses were detected in the overlay fabric
  D. There are three active client overlay VLANs in the overlay fabric
  A. The underlay loopback addresses are in the 172 21 11 x range.

  ---

  Explanation/Reference:

  The CLI output displays EVPN routes and their corresponding next hops. The "Route Distinguisher" entries followed by IP addresses in the 172.21.11.x range indicate these are loopback addresses used by the underlay network. The underlay network provides the basic routing and forwarding plane for the overlay network that EVPN is part of. These loopback addresses are crucial for the proper functioning of the EVPN control plane.

• Question 58:

  Which option shows the correct Banawidth Control for 1024 kbpsdown and 2048 Kops up for the SSID?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D

  ---

  Explanation/Reference:

  The correct Bandwidth Control settings for 1024 Kbps down and 2048 Kbps up for the SSID are shown in Option D. In Option D, the downstream is set at 1024 Kbps and the upstream at 2048 Kbps, both configured per user, which matches the requested configuration. This setup ensures that each user has a guaranteed bandwidth allocation of the specified rates when connected to the SSID, providing a controlled and predictable user experience.

• Question 59:

  Exhibit.

  

  A customer is reporting mat connectivity is Tailing for some wireless client Devices. What are your conclusions from the capture? (Select two.)

  A. The client does not have an ARP entry for me default gateway.
  B. The network is using WPA2-PSK key management.
  C. The network is using WPA3-SAE key management.
  D. The client is not receiving an IP address.
  E. The client does not support beamforming.
  B. The network is using WPA2-PSK key management.
  D. The client is not receiving an IP address.

  ---

  Explanation/Reference:

  The capture shows messages related to WPA key management, indicating WPA2-PSK is being used. Also, the capture includes a DHCP request from the client but no corresponding DHCP ACK, suggesting the client is not receiving an IP address, which could explain the connectivity failure.

• Question 60:

  After onboarding three new AOS 10 gateways using the full-setup methodinto the same Central group, a customer cannot log in to one of the gateways using the HPE Aruba Networking Central remote console due to an incorrect password.

  A. The admin password created using full-setup does not match the global Central admin password.
  B. The admin password created during the run-setup process is not configured to allow me remote console access
  C. The admin password created during the full-setup process does not match the Central group admin password
  D. The admin password created at the Central group level has expired
  C. The admin password created during the full-setup process does not match the Central group admin password

  ---

  Explanation/Reference:

  When onboarding devices into a centralized management system, each device can have its individual admin password set during the onboarding process. If this password doesn't match what is expected at the group level in the central management platform, login issues such as the one described can occur.
