Question 1

Your company needs to run BGP in a multi-homed configuration to two ISPs, advertising a block of public address space you own. Which AS number would be an example of a suitable number?

A64813

B63472

C65535

D65218

Answer : B

For BGP in a multi-homed configuration advertising public IP blocks, the AS number should be a valid public AS number allocated by the regional internet registry (RIR). Numbers in the private AS range (64512--65534) are not suitable for public Internet announcements.

63472 falls in the public AS range (16-bit AS numbers below 64512).

64813, 65535, and 65218 are in the private or reserved range.

Therefore, 63472 is an example of a suitable public AS number.

Question 2

Refer to the exhibit.

You have recently implemented a VoWiFi solution with QoS, but users are experiencing poor call quality during busy periods. Based on the output generated after some test calls, what change should you make to improve call quality?

Areconfigure DSCP mapping

Benable WMM for the SSID

Cdisable AirSlice

Dupdate ACLs

Answer : B

Question 3

Your customer's CISO would like to deploy colorless ports across the network. Which will you need to configure to meet this requirement?

AVRRP

BVNBT

CVSF

DVRF

Answer : B

Colorless ports allow network devices to move or replace endpoints without changing port-level configurations, typically by automatically assigning network policies dynamically to any port.

HPE Aruba's solution for colorless ports is the VNBT (Virtual Network Boundary Tagging) feature. VNBT allows dynamic segmentation of traffic, so ports can automatically take on the policies assigned to devices regardless of physical port location.

VRRP is a first-hop redundancy protocol and unrelated to port colorlessness.

VSF (Virtual Switching Framework) is for switch stacking.

VRF (Virtual Routing and Forwarding) is for traffic segmentation.

Thus, VNBT is the correct feature to meet colorless port requirements.

Question 4

A customer has interfering devices that are seen over the air. They contact you and ask you to configure RAPIDS to help identify interfering and rogue APs. HPE Aruba Networking Central identifies a rogue AP and displays the connected switch port.

How can HPE Aruba Networking Central identify which switch port the AP is connected to?

ADevice profiling on the switch

BFrom the switch MAC address table

CFrom the switch LLDP neighbors table

DFrom the AP MAC address table

Answer : B

Question 5

Your customer's CX switches are managed in HPE Aruba Networking Central. If a VSX primary switch is accidentally powered off, which alert will be triggered?

ASwitch Reboot

BSwitch Stack Conductor Change

CSwitch Disconnected

DSwitch STP Root Change

Answer : C

When a VSX primary switch is powered off, it loses connectivity with management systems such as HPE Aruba Central. This causes the management system to trigger a 'Switch Disconnected' alert because the switch is no longer reachable.

'Switch Reboot' alerts would indicate a restart, not power off.

'Switch Stack Conductor Change' refers to stack leadership changes, not VSX primary down.

'Switch STP Root Change' relates to Spanning Tree Protocol root bridge changes.

Hence, powering off the VSX primary causes a 'Switch Disconnected' alert.

Question 6

Refer to the exhibit:

The customer would like to utilize Dynamic Segmentation for wired users in Building B. Which statement is true about the scenario?

AThe CX 6100 switches need to have a GRE tunnel to the HPE Aruba Networking 9200.

BThe CX 6100 switches need to have a static VXLAN tunnel to the HPE Aruba Networking CX 8325.

CThe CX 6100 switches would need to be replaced with CX 6300 models.

DThe CX 6100 switches need to have the CX Advanced license applied to support the requirement.

Answer : C

Dynamic Segmentation (DS) requires certain capabilities on the switches to support user role assignment and traffic segmentation based on identity. The CX 6100 series switches do not support Dynamic Segmentation due to hardware and feature limitations. Therefore, they must be replaced with CX 6300 models, which support DS features natively.

Options involving GRE tunnels or VXLAN tunnels relate to traffic forwarding but do not enable DS on unsupported hardware.

Applying licenses does not upgrade hardware capabilities for DS.

Question 7

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.
