1. Question 1

   You are deploying a new HPE Aruba Networking switch in a converged network that carries both data and voice traffic. During planning, you need to ensure that voice packets are prioritized over general web traffic to maintain call quality. Which of the following best describes the network feature you should implement to address this requirement?

   AQuality of Service (QoS) to classify and prioritize traffic based on application type
   

   BSpanning Tree Protocol (STP) to prevent loops and reduce latency on voice paths
   

   CLink aggregation to increase bandwidth capacity for all traffic equally
   

   DVirtual LAN (VLAN) segmentation to isolate voice traffic on a separate broadcast domain
   

   Correct answer: A

   The correct answer is Quality of Service (QoS). QoS is specifically designed to manage traffic prioritization in converged networks by classifying different types of traffic (voice, video, data) and applying policies to ensure critical applications receive preferential treatment. While VLANs can segment traffic and link aggregation increases overall bandwidth, neither directly addresses traffic prioritization. STP manages loop prevention, not traffic priority.

2. Question 2

   A network technician is troubleshooting connectivity issues on an HPE Aruba Networking switch. She needs to verify VLAN configuration, port membership, and trunk status across multiple interfaces. When she executes the command show vlan, the output shows VLAN 100 is active, but servers connected to ports 1-4 are unreachable. Which show command should she use next to determine if the ports are properly assigned to VLAN 100?

   A<code>show interface brief</code> to see port status and configured IP addresses
   

   B<code>show vlan id 100</code> or <code>show vlan 100</code> to display detailed VLAN membership and tagged/untagged port status
   

   C<code>show spanning-tree</code> to verify there are no STP-blocked ports affecting connectivity
   

   D<code>show running-config</code> to review the entire switch configuration at once
   

   Correct answer: B

   The correct answer is show vlan id 100 or show vlan 100. This command displays detailed information about a specific VLAN, including which ports are tagged, untagged, or not members of that VLAN. This directly answers the question of whether ports 1-4 are properly assigned to VLAN 100.

   Show interface brief shows port status but not VLAN membership details. Show spanning-tree is useful for redundancy troubleshooting but not VLAN assignment. Show running-config is too verbose for quick verification of port membership in a specific VLAN. The targeted VLAN-specific show command is the most efficient troubleshooting approach.

3. Question 3

   How do you configure an in-band management IP address for the HPE Aruba Networking CX 4100i switch?

   Ainterface mgmt
   ip address 10.10.10.10/24
   routing
   

   Binterface vlan 1
   ip address 10.10.10.10/24
   routing
   

   Cinterface vlan 1
   ip address 10.10.10.10/24
   

   Dinterface mgmt
   ip address 10.10.10.10/24
   

   Correct answer: C

   The correct answer is C. In-band management uses the production switching network rather than the dedicated out-of-band management port. For an HPE Aruba Networking CX 4100i switch, HPE Aruba Networking AOS-CX documentation states that configuring the in-band management interface begins by entering interface vlan 1. The guide then shows that the in-band management interface can be configured with DHCP or with a static IP address. Therefore, assigning ip address 10.10.10.10/24 under interface vlan 1 is the correct in-band management configuration from the choices. Option A is incorrect because interface mgmt is the out-of-band management interface, not in-band management. Option D is also out-of-band for the same reason. Option B is not the best answer because routing is not required under the VLAN interface for this in-band management IP configuration. The essential configuration is the VLAN interface with the static IP address

   
   

4. Question 4

   Refer to the exhibit:

   

   What information is provided based on this output?

   AThe switch does not have management VRF defined for connectivity.
   

   BHPE Aruba Networking Central has been manually disabled on the switch.
   

   CThe switch does not have a valid support contract.
   

   DHPE Aruba Networking Central configuration is in the factory default.
   

   Correct answer: B

   The correct answer is B. HPE Aruba Networking Central has been manually disabled on the switch. The key line in the output is Central admin state : disabled. HPE Aruba Networking AOS-CX documentation for the show aruba-central command provides an example of a switch when Aruba Central is disabled, showing Central admin state : disabled, Central connection values as N/A, and Central support mode as disabled. This indicates that the switch's Central administrative state is disabled, so it is not attempting to connect to HPE Aruba Networking Central. Option A is incorrect because the VRF for connection : N/A value is a result of Central being disabled, not proof that the management VRF does not exist. Option C is incorrect because this command output does not report support-contract validity. Option D is incorrect because the factory-default Central behavior is not what is being shown; the output specifically reflects Central being disabled. Therefore, the correct interpretation is that Central has been manually disabled on the switch. (arubanetworking.hpe.com)

   
   

5. Question 5

   A technician installed a new HPE Aruba Networking 580EX Series access point, which is cabled back to an HPE Aruba Networking CX 6000 48G 4SFP switch. However, there are no lights on the access point.

   What could cause this issue?

   AThe wrong VLAN has been configured.
   

   BThe switch does not have enough PoE budget per port.
   

   CSTP has not been configured.
   

   DThe access point cannot connect to HPE Aruba Networking Central.
   

   Correct answer: B

   The correct answer is B. The switch does not have enough PoE budget per port. The HPE Aruba Networking 580EX Series access point requires appropriate power to boot and illuminate its LEDs. HPE Aruba Networking documentation states that the 580EX Series supports 802.3bt Class 6 power or AC power. A standard HPE Aruba Networking CX 6000 48G 4SFP switch, such as the R8N86A model, is a non-PoE switch; the PoE-capable version is identified separately as the CX 6000 48G Class 4 PoE 4SFP 740W switch. Even when using a PoE-capable CX 6000 model, Class 4 PoE provides up to 30W per port, while the AP requires 802.3bt Class 6 or AC power for normal operation. Therefore, if the AP has no lights, the most likely cause from the options is insufficient or unavailable PoE power from the switch port. A wrong VLAN, missing STP configuration, or failure to connect to HPE Aruba Networking Central would not normally prevent the AP from receiving power and showing LEDs.
