HP HPE7-A07 Online Questions & Answers

• Question 21:

  Exhibit.

  

  After configuring VRRP between sw-1 and SW-2. you notice that both switches are showing as active. What could be the reason for this issue?

  A. VRRP preemptive mode is disabled.
  B. SW-1 cam reach SW-2 on VLAN 10.
  C. Both switches are configured as VRRP 'primary.'
  D. SW-2 has no priority configurations for VRRP 1.
  C. Both switches are configured as VRRP 'primary.'

  ---

  Explanation/Reference:

  In VRRP (Virtual Router Redundancy Protocol), only one switch should be the primary (master) for a given virtual IP address, with the other switches being backups. If both switches are showing as active, it suggests a misconfiguration where both are set to act as the primary for the same VRRP group. The exhibits provided indicate that both switches believe they are the active or primary for the VRRP group, which is an incorrect configuration.

• Question 22:

  Exhibit.

  

  Which user role will be assigned when a voice client tries to connect for the first time, but the RADIUS server is unavailable?

  A. CRITICAl_AUTH
  B. DEFAULT_AUTH
  C. CRIT1CAL_V0ICE
  D. PRE_AUTH
  C. CRIT1CAL_V0ICE

  ---

  Explanation/Reference:

  In the provided configuration for interface 1/1/7, there are roles specified for different scenarios concerning authentication. When a voice client attempts to connect and the RADIUS server is unreachable, the role that is assigned is the one specified as the "critical-voice-role". In this case, the "CRITICAL_VOICE" role is configured to be assigned under such circumstances, ensuring that voice clients receive appropriate network access permissions even when the RADIUS server is not available to authenticate them.

• Question 23:

  A campus topology uses VSXwith a collapsed core topology.The customer added redundant SFP+ transceivers and reconfigured their mobility gateways from a single link to an aggregate Link.You are asked to verify the CLI output for the link aggregation configuration for one of the mobility gateway cluster members below.

  

  What is a valid configuration?

  

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

  ---

  Explanation/Reference:

  The configuration shown in Option A is a valid configuration for a multi-chassis link aggregation (MC-LAG) setup. It specifies the use of LACP (Link Aggregation Control Protocol) with a fast rate of LACP PDUs exchange, which is appropriate for creating a resilient and high-throughput link aggregation. The 'vlan trunk allowed all' command allows all VLANs across the trunk, and 'vlan trunk native 100' sets VLAN 100 as the native VLAN for untagged traffic.

• Question 24:

  You deployed UBT tosecurely tunnel traffic from user desktop PCs connected behind VOIP phones Ail other non-UBT dents are connected to a different network. After the deployment users reported interruptions lo their phone service

  A. The VLAN on which UBT clients are placed is not configured on the switch uplink and traffic from the VoIP phones is being dropped
  B. You tailed to correctly configure a user-defined VRF to support the UBT clients behind the VoIP phones, causing traffic to drop.
  C. Broadcast/multicast packets are copied to both the tunnel and locally, causing duplicate packets and network instability
  D. The UBT client broadcast/multicast packets returned to the same switch port and corrupted the phones IMC table
  A. The VLAN on which UBT clients are placed is not configured on the switch uplink and traffic from the VoIP phones is being dropped

  ---

  Explanation/Reference:

  If users report interruptions to their phone service after the deployment of User-Based Tunneling (UBT), it can be due to the VLAN designated for UBT clients not being configured on the switch uplink. As a result, traffic from VoIP phones, which may be trying to use the same VLAN, could be dropped, leading to service interruptions. Ensuring that the VLAN is properly configured on the switch uplink is crucial for the seamless operation of UBT clients and VoIP services.

• Question 25:

  Exhibit.

  

  Which statement is true?

  A. The SSID supports RC4 encryption.
  B. The SSID supports 802.11nac clients.
  C. The SSID supports implicit beamforming.
  D. The SSID supports sending neighbor reports.
  B. The SSID supports 802.11nac clients.

  ---

  Explanation/Reference:

  The SSID supports 802.11ac clients, which is indicated by the "High Throughput" and "Very High Throughput" options being enabled. These are terms associated with the 802.11ac wireless standard, indicating that the SSID can serve clients that support this technology.

• Question 26:

  Your customer's employees connected to a wired network are complaining about a poor user experience. The customer has UXI sensors deployed on their premises. These sensors nave been running for multiple months. They are testing both the wired network (using the wired Interface of each sensor) and the wireless networks. Your customer used the UXI dashboard to find the reason for the poor userexperience to find more details, the customer asked you to check the packet captures that have been downloaded from the sensors using the UXI dashboard.

  From the zip file downloaded from the UXI sensors, you checked the "datagrams" .pcap file, but you were not able to find any issues How can you explain this?

  A. The "datagrams- pcap file only contains me successful tests Failed tests are contained in the "datagrams-failed" .pcap file
  B. The UXI sensor could not upload the latest test results to the cloud, so the packet capture is outdated
  C. The datagrams captured on the physical Ethernet interface are in a different .pcap file.
  D. The default filers of the packet captures do not allow tailed tests to be captured by the sensor
  A. The "datagrams- pcap file only contains me successful tests Failed tests are contained in the "datagrams-failed" .pcap file

  ---

  Explanation/Reference:

  It is a common practice to separate successful and failed test results into different files for ease of troubleshooting. If the "datagrams.pcap" file shows no issues, it's likely because it only contains successful test data, and the failed tests that could explain the poor user experience would be in a different file, such as "datagrams-failed.pcap."

• Question 27:

  An ACME company employee complained about a recent poor-quality VoIP call while moving aroundtheir office environment HPE Aruba Networking Central reported a fair UCC score for this callwhile your VoIP engineer reported that their systems reported a MOS of 2,3. The VoIP devices are operatingover the 5GHz frequency band.

  What are the possible contributing factors? (Select two.)

  A. Coverage AP deployment plans generally don't support enough cell overlap for VoIP.
  B. 802.tr is enabled in the WLAN Security settings.
  C. There was localized interference at the caller's location
  D. 802.1K is disabled in the WLAN Security settings
  E. The client roamed into an area that continuously operates Zigbee.
  A. Coverage AP deployment plans generally don't support enough cell overlap for VoIP.
  E. The client roamed into an area that continuously operates Zigbee.

  ---

  Explanation/Reference:

  VoIP quality can be negatively impacted by insufficient cell overlap in AP deployment plans, which can cause poor handoffs between APs as a user moves around. This results in a degraded VoIP experience. Additionally, roaming into an area with continuous Zigbee operation can cause interference with the 5GHz frequency band, further contributing to poor VoIP call quality. The Zigbee communication protocol operates on the same frequency band as Wi-Fi and can introduce noise and interference, which leads to a reduced MOS score, as reported by the VoIP engineer.

• Question 28:

  Anetworkadministrator accesses HPE Aruba Networking Central and notices that visitors consume too much internet bandwidth starving employee traffic when accessing an external service.Therefore,the administrator wants to limitwireless bandwidth to 60 Mops in both directions among all users in the voice rote and no more than 10 Mops in both directions for YouTube traffic. Deep packet inspection, web contentclassification, andfirewall visibility are enabled.

  Which configurations are required to accomplish this task? (Select two.)

  

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

  ---

  Explanation/Reference:

  To achieve the bandwidth limits set by the network administrator, both per-application and total limits need to be configured. Option B shows the configuration for setting a per-application bandwidth limit, which can restrict YouTube traffic to 10 Mbps in both directions. Option D shows the configuration for setting a total bandwidth limit for all users within the voice role to 50000 Kbps (or 50 Mbps), satisfying the requirement to restrict total wireless bandwidth. By applying these configurations in HPE Aruba Networking Central, the administrator will successfully implement the necessary controls to ensure that visitor traffic does not impede the network performance for employee traffic, aligning with the capabilities of Aruba solutions to manage and prioritize network resources effectively.

• Question 29:

  A network administrator wants to configure an 802 1X supplicant for a wireless network that includes the following:

  1.

  AES encryption

  2.

  EAP-MSCHAPv2-based user and machine authentication

  3.

  validation of server certificate in Microsoft Windows 10

  The network administrator creates a WLAN profile and selects the change connection settings option Then the network administrator changes the security type to Microsoft Protected EAP (PEAP) and enables user and machine authentication

  under Additional Settings.

  What must the network administrator do next to accomplish the task?

  A. Enable user authentication
  B. Change the security type to Microsoft: Smart Card or other certificate.
  C. Change default RC4 encryption for AES
  D. Enable server certificate validation
  A. Enable user authentication
  D. Enable server certificate validation

• Question 30:

  You are testing the use of the automated port-access role configuration process using RadSec authentication over VXLAN. During your testing you observed that the RadSec connection will fan during the digital certificate exchange What would be the cause of this Issue?

  A. The RadSec server was defined on the switch using an IPv6 address that was unreachable
  B. Tracking mode was set to "dead-only", and the RadSec server was marked as unreachable.
  C. The switch is configured to establish a TLS connection with a proxy server, not the radius server.
  D. The RADIUS TCP packets are Being dropped and the TLS tunnel is not established.
  D. The RADIUS TCP packets are Being dropped and the TLS tunnel is not established.

  ---

  Explanation/Reference:

  During the testing of RadSec authentication over VXLAN, if the RadSec connection fails during the digital certificate exchange, it typically indicates an issue with the establishment of the TLS tunnel, which is required for RadSec's secure communication. The failure of TLS tunnel establishment can occur due to RADIUS TCP packets being dropped, preventing the secure exchange of digital certificates necessary for RadSec authentication. The other options, such as IPv6 address reachability, tracking mode settings, and proxy server misconfiguration, are not directly related to the failure of the TLS tunnel establishment during the certificate exchange process
