Question 1

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 2

A customer is experiencing authentication failures when clients connect to a new EAP-TLS SSID.

Based on the logs and packet capture above, what is the cause of the failure?

AThe client cannot validate the RADIUS server's certificate

BThe MTU in the path between the AP and HPE Aruba Networking ClearPass is too small

CHPE Aruba Networking ClearPass cannot validate the user's certificate

DThe access point doesn't have the correct root CA certificate installed

Answer : B

Question 3

Based on the output, which Local Priority (LP) value will be applied to an incoming packet from interface 2/1/39 marked with DSCP 46 and CoS 7?

ALocal Priority 1

BLocal Priority 5

CLocal Priority 7

DLocal Priority 0

Answer : A

The Local Priority (LP) applied to an incoming packet marked with DSCP 46 and CoS 7 depends on the configured QoS mapping.

DSCP 46 corresponds to Expedited Forwarding (EF), which is typically mapped to the highest priority.

CoS 7 also indicates high priority.

According to the QoS policy shown, the LP assigned is 1, indicating the highest priority level.

Question 4

You are configuring OSPF between two CX switches but cannot see any neighbors. Based on the output, how would you fix the problem?

ARemove the max-metric router-lsa on-startup to allow faster formation of adjacency.

BConfigure ip ospf network broadcast on the VLAN 182 interface.

CConfigure no ip ospf cost 100 on the VLAN 182 interface.

DConfigure no passive-interface vlan182 on the switch.

Answer : D

OSPF neighbors not forming adjacency and stuck in the 2WAY state typically indicates that the interface is set to passive mode, preventing OSPF Hello packets from being sent or received on that interface.

Removing passive mode on VLAN 182 allows OSPF Hello messages to be exchanged and adjacency to form.

Options involving network type or costs do not affect adjacency states related to passive interfaces.

The max-metric router-lsa on-startup affects LSA advertisements, not adjacency formation.

Therefore, the fix is to configure no passive-interface vlan182.

Question 5

Which statement is valid when enabling ARP protection features on HPE Aruba Networking CX switches?

AOnce you enable DHCP snooping, you can enable ARP protection, and you will have full information to mitigate security risks.

BIn an active network, you should generally wait at least a week after enabling DHCP snooping to enable ARP protection.

CClient lease time on the DHCP server should be at least 3600s before enabling ARP protection.

DDHCP server utilization is required for IP to MAC binding to enable ARP protection.

Answer : B

When enabling ARP protection, it is best practice to wait at least a week after enabling DHCP snooping before enabling ARP protection in a live network. This allows the DHCP snooping binding table to stabilize, ensuring ARP protection has accurate IP-MAC bindings, reducing false positives.

Immediate ARP protection may cause legitimate traffic to be dropped.

Lease times and DHCP server utilization are less critical.

This staged approach minimizes disruption.

Question 6

A customer's infrastructure is set up to use both primary and secondary gateway clusters on the SSID profile based on best practices. Why do they have an equal split of their 144 APs across the primary gateway cluster and the secondary gateway cluster?

AThe secondary gateway cluster is a heterogeneous cluster with four nodes.

BThe primary and secondary gateway clusters are up, and the cluster preemption is enabled.

CThe primary and secondary gateway clusters are up, but the cluster preemption is not enabled.

DThe secondary gateway cluster is a homogeneous cluster with six nodes.

Answer : C

Question 7

Refer to the exhibit.

To which devices has AP-1 established tunnels?

AA pair of gateways within a cluster

BA pair of switches running VXLAN

CA single gateway within a cluster

DA pair of standalone gateways

Answer : A
