  1. Question 1Network Management with HPE Aruba Networking Central

    A company runs three campus buildings with AOS-CX switches managed in HPE Aruba Networking Central. The administrator wants every switch in one building to share the same VLAN and port settings and wants to change those settings once for the whole set. What is the most appropriate approach?

    1. APlace the switches in one device group in Central and set the shared configuration at the group level
    2. BEdit each switch separately through its local CLI so that the settings stay consistent over time
    3. CCreate a separate site for each switch and copy the configuration into every site by hand
    4. DSave one switch's running configuration to a TFTP server and have each switch fetch that file only when it reboots
    Show answer and explanation
    Correct answer: A

    Device groups in Central hold the configuration that is pushed to the devices assigned to them, so one change at group level applies to every member. Sites organize devices by location for monitoring and do not carry the shared configuration. Local CLI edits and manual copies drift out of step over time, and a TFTP fetch at reboot is not how Central manages its devices.

  2. Question 2Managing Wired Networks with Central

    A distribution switch must carry VLANs 10, 20 and 30 to an access switch over one link, with each VLAN tagged so both ends can separate them. Which port mode should be configured on that link?

    1. AAccess mode, with the link assigned to VLAN 10 only and the other two VLANs left unassigned
    2. BTrunk mode, which carries several tagged VLANs across the same link
    3. CAccess mode, with all three VLANs assigned to the same port so that they share one broadcast domain
    4. DMirror mode, which copies the VLAN traffic to a monitoring port while the link itself carries no tags
    Show answer and explanation
    Correct answer: B

    A trunk carries multiple VLANs with 802.1Q tags, which is what a switch-to-switch link needs here. An access port carries only one untagged VLAN, so the access options would drop VLANs or merge them, and mirror mode does not carry traffic between the switches.

  3. Question 3Introduction to AOS-10

    Which change is a key architectural difference in AOS-10 compared with earlier AOS releases that relied on a Mobility Master?

    1. AManagement and configuration are handled through Central, so no on-premises Mobility Master is needed
    2. BAccess points are connected directly to the internet and no gateway is used anywhere in the design
    3. CGateways are managed only through their local command line, and Central is used only for generating reports
    4. DThe Mobility Master moves to the cloud and becomes the forwarding point for all gateway client traffic
    Show answer and explanation
    Correct answer: A

    AOS-10 moves management and configuration into Central, which removes the need for an on-premises Mobility Master. The other options describe local-only gateway management, a design with no gateways, and a Mobility Master that forwards client traffic, none of which matches AOS-10.

  4. Question 4Network Management with HPE Aruba Networking Central

    Within the Central management hierarchy, which statement about groups and sites is correct?

    1. ASites hold the configuration that is pushed to devices, while groups are used only for location-based health reports
    2. BGroups hold the configuration pushed to devices, while sites organize devices by physical location for monitoring
    3. CGroups and sites are two names for the same container, so they always hold identical configuration and identical status
    4. DEach site must contain exactly one device, which makes group-level configuration unnecessary for that site
    Show answer and explanation
    Correct answer: B

    Groups carry the configuration that Central pushes to devices, and sites are used to organize devices by physical location for monitoring. Swapping those roles, treating the two as the same container, or requiring one device per site are all incorrect.

  5. Question 5Managing Wired Networks with Central

    Two AOS-CX core switches are configured as a VSX pair. An access switch connects to both with one link aggregation, so the loss of one core switch does not isolate it. What does VSX provide that makes this design work?

    1. AA separate spanning tree instance on the access switch that blocks every uplink toward the core pair
    2. BA routing table exchange only, so the access switch must rely on static routes instead of an aggregate
    3. CBoth core switches are given the same management IP address, and only the active one forwards traffic at any time
    4. DThe two core switches appear as one logical switch to the access switch, which can form a single LAG across both
    Show answer and explanation
    Correct answer: D

    VSX makes the pair look like one logical switch to the downstream device, which allows a LAG to span both members. The other options describe a spanning tree blockage, a routing-only exchange and an active-standby address scheme, none of which is how VSX presents the pair.

How to prepare for HPE6-A90

  1. Read the official HPE outline first (exam page), so you know exactly what is in scope.
  2. Give the most time to Network Management with HPE Aruba Networking Central and Managing Wired Networks with Central: together they make up 67% of the questions.
  3. Take the free 30-question practice test and note which topics you miss.
  4. Go back to the weak topics, then test again. A practice score shows where to study; it does not predict your exam result.
