HP HPE7-A01 Online Questions & Answers

• Question 81:

  How do you allow a new VLAN 200 for downstream access switch with VSX pair using VSX LAG?

  A. vlan trunk allowed 200 in MLAG 1
  B. vlan trunk add 100 in MLAG1
  C. vlan trunk allowed all in LAG 1 multi-chassis
  D. vlan trunk add 100 in LAG1 multi-chassis
  C. vlan trunk allowed all in LAG 1 multi-chassis

• Question 82:

  A wireless engineer is troubleshooting sticky clients in a Wi-Fi 6 deployment. Many clients remain associated to a lower-performing AP even when a better AP is available nearby.

  Which Aruba feature should be enabled to improve this behavior?

  A. AirMatch
  B. ClientMatch
  C. ClearPass
  D. RadSec
  B. ClientMatch

  ---

  Explanation

  ClientMatch is the correct feature because it is designed to improve client distribution and roaming decisions by steering clients toward a more suitable AP based on RF and client conditions. The problem described is a classic sticky-client scenario. AirMatch focuses on radio optimization at the infrastructure level, such as channel and power planning, rather than per-client reassignment logic. ClearPass and RadSec address access control and RADIUS transport security, not

  AP selection behavior.

• Question 83:

  Your customer has asked you to assign a switch management role for a new user.

  The customer requires the user role to only have Web Ul access to the System > Log page and only have access to the GET method for REST API for the / logs/event resource

  Which default AOS-CX user role meets these requirements?

  A. administrators
  B. auditors
  C. sysops
  D. operators
  A. administrators

  ---

  Explanation

  The auditors role is the default AOS-CX user role that meets the requirements of having Web UI access to the System > Log page and having access to the GET method for REST API for the /logs/event resource. The auditors role has a level of 1 and allows read-only access to most commands except those related to security or passwords. It also allows access to the Web UI and REST API with limited permissions. The other options are incorrect because they either have higher levels of access or do not allow access to the Web UI or REST API.

• Question 84:

  Refer to the image.

  

  Your customer is complaining of weak Wi-Fi coverage in their office. They mention that the office on the other side of the hall has much better signal.

  What is the likely cause of this issue7

  A. The AP is a remote access point.
  B. The AP is using a directional antenna.
  C. The AP is an outdoor access point.
  D. The AP is configured in Mesh mode
  B. The AP is using a directional antenna.

  ---

  Explanation

  The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna. A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario.

• Question 85:

  Which standard supported by some Aruba APs can enable a customer to accurately locate wireless client devices within a few meters?

  A. 802.11mc
  B. 802.11W
  C. 802.11k
  D. 802.11r
  A. 802.11mc

  ---

  Explanation

  The standard that is supported by some Aruba APs and can enable a customer to accurately locate wireless client devices within a few meters is A. 802.11mc. 802.11mc is an IEEE standard that enables computing devices to measure the distance to nearby Wi-Fi access points using a technique called Fine Timing Measurement (FTM). FTM uses precise timestamps to calculate the round-trip time of Wi-Fi frames between the device and the access point, and then converts it to a distance estimate. By using multiple access points and triangulation methods, the device can determine its location with high accuracy 1.

  According to the Aruba document 802.11mc Support, this feature is supported on 500 Series, 510 Series, 530 Series, 550 Series, 560 Series and 570 Series access points. These APs act as FTM responders to time measurement queries sent from a client. To configure the AP to send FTM responses, you need to enable the ftm-responder-enable parameter in the WLAN SSID profile 1.

• Question 86:

  In AOS 10. which session-based ACL below will only allow ping from any wired station to wireless clients but will not allow ping from wireless clients to wired stations"? The wired host ingress traffic arrives on a trusted port.

  A. ip access-list session pingFromWired any user any permit
  B. ip access-list session pingFromWired user any svc-icmp deny any any svc-icmp permit
  C. ip access-list session pingFromWired any any svc-icmp permit user any svc-icmp deny
  D. ip access-list session pingFromWired any any svc-icmp deny any user svc-icmp permit
  D. ip access-list session pingFromWired any any svc-icmp deny any user svc-icmp permit

  ---

  Explanation

  A session-based ACL is applied to traffic entering or leaving a port or VLAN based on the direction of the session initiation. To allow ping from any wired station to wireless clients but not vice versa, a session-based ACL should be used to deny icmp echo traffic from any source to any destination, and then permit icmp echo-reply traffic from any source to user destination. The user role represents wireless clients in AOS 10.

• Question 87:

  Your manufacturing client is having installers deploy seventy headless scanners and fifty IP cameras in their warehouse.

  These new devices do not support 802 1X authentication.

  How can HPE Aruba reduce the IT administration overhead associated with this deployment while maintaining a secure environment using MPSK?

  A. Have the installers generate keys with ClearPass Self Service Registration.
  B. Have the MPSK gateway derive the unique pre-shared keys based on the MAC OUI.
  C. Use MPSK Local to automatically provide unique pre-shared keys for devices.
  D. MPSK Local will allow the cameras to share a key and the scanners to share a different key
  C. Use MPSK Local to automatically provide unique pre-shared keys for devices.

  ---

  Explanation

  MPSK Local is a feature that can reduce the IT administration overhead associated with deploying devices that do not support 802.1X authentication while maintaining a secure environment. MPSK Local allows the switch to automatically generate and assign unique pre-shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require manual intervention by the installers or the MPSK gateway, or they do not provide unique pre-shared keys for devices.

• Question 88:

  With the Aruba CX 6200 24G switch with uplinks or 1/1/25 and 1/1/26, how do you protect client ports from forming layer-2 loops?

  A. int 1/1/1-1/1/24, loop-protect
  B. int 1/1/1-1/1/28. loop-protect
  C. int 1/1/1-1/1/28. loop-guard
  D. int 1/1/1-1/1/24. loop-guard
  A. int 1/1/1-1/1/24, loop-protect

  ---

  Explanation

  The command loop-protect enables loop protection on each layer 2 interface (port, LAG, or VLAN) for which loop protection is needed. Loop protection can find loops in untagged layer 2 links, as well as on tagged VLANs.

• Question 89:

  Two AOS-CX switches are configured with VSX at the the Access-Aggregation layer where servers attach to them An SVI interface is configured for VLAN 10 and serves as the default gateway for VLAN 10. The ISL link between the switches

  fails, but the keepalive interface functions. Active gateway has been configured on the VSX switches.

  

  What is correct about access from the servers to the Core? (Select two.)

  A. Server 1 can access the core layer via the keepalrve link
  B. Server 2 can access the core layer via the keepalive link
  C. Server 2 cannot access the core layer.
  D. Server 1 can access the core layer via both uplinks
  E. Server 1 and Server 2 can communicate with each other via the core layer
  F. Server 1 can access the core layer on only one uplink
  D. Server 1 can access the core layer via both uplinks
  E. Server 1 and Server 2 can communicate with each other via the core layer

  ---

  Explanation

  These are the correct statements about access from the servers to the Core when the ISL link between the switches fails, but the keepalive interface functions. Server 1 can access the core layer via both uplinks because it is connected to VSX-A, which is still active for VLAN 10. Server 2 can also access the core layer via its uplink to VSX-B, which is still active for VLAN 10 because of Active Gateway feature. Server 1 and Server 2 can communicate with each other via the core layer because they are in the same VLAN and subnet, and their traffic can be routed through the core switches. The other statements are incorrect because they either describe scenarios that are not possible or not relevant to the question.

• Question 90:

  Your Director of Security asks you to assign AOS-CX switch management roles to new employees based on their specific job requirements After the configuration was complete, it was noted that a user assigned with the administrators role did not have the appropriate level of access on the switch.

  The user was not limited to viewing nonsensitive configuration information and a level of 1 was not assigned to their role.

  Which default management role should have been assigned for the user?

  A. sysadmin
  B. operators
  C. helpdesk
  D. config
  B. operators

  ---

  Explanation

  The default management role that should have been assigned for the user is B. operators.

  The operators user role is a predefined role that allows users to view nonsensitive configuration information on the switch, such as interfaces, VLANs, routing protocols, statistics, and more. The operators user role has a privilege level of 1, which is the lowest level of access on the switch 1.

  The administrators user role is a predefined role that has full access to all switch configuration information and all REST API methods. This role is more than what the Director of Security requires 1.
