Question 1

An AOS-10 multi-site deployment has sites with AP-only bridged SSIDs and other sites with APs and gateways operating tunneled SSIDs. Client session state sync errors exist between secure lab environments and public-facing areas at several sites.

What is causing the issues?

AThe sites with issues are the overlay AP with gateway sites because the connection to HPE Aruba Networking Central is interrupted.

BThe DTLS connections are down between APs in the lab and APs in public areas.

CThe affected clients are associated with an SSID with 11r and 11k disabled.

DThe sites with issues are the AP-only deployments because the connection to HPE Aruba Networking Central is interrupted.

Answer : D

Question 2

Refer to the partial exhibit from an HPE Aruba Networking CX 8325:

A new port 1/1/44 needs to be configured to connect to a 29301, which has the following configuration:

Which configuration would be used?

AOption A

BOption B

COption C

DOption D

Answer : A

The question relates to configuring port 1/1/44 on an Aruba CX 8325 switch to connect to a 2930F switch (Aruba 2930F series). The key factor is interoperability between these two devices, especially regarding link aggregation and port channel settings.

The Aruba 2930F typically uses static or LACP link aggregation with standard settings. To connect an Aruba CX 8325 port to a 2930F port, the CX configuration must align with the 2930F settings, particularly regarding:

Enabling LACP (Link Aggregation Control Protocol) on the port.

Correct VLAN tagging or trunk mode.

Matching speed and duplex settings.

From the options given, answer A corresponds to enabling LACP with appropriate trunk configuration that matches the 2930F. The other options either have mismatches in aggregation or trunking mode or missing LACP.

Question 3

What directly affects the MCS used by wireless stations? (Select two.)

ASNR

BChannel utilization

CNumber of connected clients

DRetry rate

EFrequency band

Answer : A, D

Question 4

You are implementing HPE Aruba Networking CX switches in a hotel environment. Which feature would allow you to use a single subnet for the wired guests, allowing them to utilize only default gateway services and communicate with each other in a conference room but not elsewhere?

ABy assigning the guest users in the conference room to an isolated VLAN and the gateway to a primary VLAN.

BBy assigning the guest users in the conference room to a community VLAN and the gateway to a primary VLAN.

CBy assigning the guest users in the conference room to a primary VLAN and the gateway to an isolated VLAN.

DBy assigning the guest users in the conference room to an isolated VLAN and the gateway to a community VLAN.

Answer : B

In a hotel environment where a single subnet is used for wired guests, but guest devices in a conference room need to communicate with each other (and with the default gateway), while remaining isolated from other guests elsewhere, Community VLANs are appropriate.

Community VLANs allow hosts within the same VLAN community to communicate with each other and the default gateway but are isolated from hosts in other communities.

Isolated VLANs block communication between ports and only allow communication to the gateway.

Therefore, assigning conference room guests to a community VLAN and the gateway to a primary VLAN allows the desired communication model.

Question 5

Your customer is a large hotel that would like to use a single VLAN per floor and isolate each room's wired network port from the others. Which CX switch feature should you recommend for the simplest solution?

AVPN

BUBT

CPVLAN

DVXLAN

Answer : C

To isolate wired ports on the same VLAN on a large scale (such as hotel rooms) but allow communication within the same VLAN for common areas, Private VLANs (PVLANs) are recommended. PVLANs allow segmentation within a single VLAN by dividing it into primary and secondary VLANs, controlling communication between ports.

VPN and VXLAN are overlay technologies for different purposes.

UBT (User-Based Tunneling) is related to wireless user segmentation, not wired port isolation.

Therefore, PVLANs provide the simplest and most effective solution to isolate room ports within a single VLAN.

Question 6

You recently added HPE Aruba Networking ClearPass as an authentication server to a group in HPE Aruba Networking Central. RADIUS authentication with Local User Roles (LUR) works fine, but the same access points cannot use Downloadable User Roles (DUR).

What should be corrected in this configuration to fix the issue with DUR?

AAdd a new Enforcement Policy of type 'WEBAUTH' on ClearPass and associate it with the matching service on ClearPass

BAdd the correct values for 'CPPM Username' and 'CPPM Password' in the authentication server configuration on HPE Aruba Networking Central

CUncheck the 'Dynamic Authorization' checkbox in the authentication server configuration on HPE Aruba Networking Central

DModify the shared secret on the switch to match CPPM using the 'radius-server host' command

Answer : B

Question 7

You have applied the following OSPF configuration but are seeing the output from the command below. What is the reason for this?

AA loopback interface hasn't been configured on Agg-2

BOSPF interfaces are passive by default

CA different OSPF process ID is used on each switch

DA Layer-3 interface has not been associated with a VRF

Answer : D

The question concerns an OSPF configuration where the interface does not come up as expected.

Common reasons for no OSPF adjacency or interface participation include:

Interfaces being passive (no adjacency formed)

Mismatched OSPF process IDs

Missing loopback interfaces (for router ID)

Layer-3 interfaces not associated with VRFs when VRFs are configured

Option D (a Layer-3 interface has not been associated with a VRF) is the root cause because in Aruba CX switches, when VRF is configured, all Layer-3 interfaces that participate in OSPF must be associated with the correct VRF instance to establish adjacency and participate correctly.

If an interface is not part of the VRF configured for OSPF, it will not appear in the OSPF interface list or form neighbors.
