Answer

Applying an ACL to a group of ports consumes the same resources as specific ACE entries

Answer

Compression is automatically enabled for ASIC TCAMs on AOS-CX switches

Answer

Applying an ACL to a group of VLANs consumes the same resources as specific ACE entries

Question 2

What is correct regarding rate limiting and egress queue shaping on AOS-CX switches?

Accepted Answer

Only a traffic rate and burst size can be defined for a queue

Answer

Limits can be defined only for broadcast and multicast traffic

Answer

Rate limiting and egress queue shaping can be used to restrict inbound traffic

Answer

Rate limiting and egress queue shaping can be applied globally

Question 3

The solution needs to support high-availability with dual-control planes.Which solution should the administrator implement?

Accepted Answer

AOS-CX 6400

Answer

AOS-CX 8325

Answer

AOS-CX 6300

Answer

AOS-CX 8400

Question 4

A company has implemented 802.1X authentication on AOS-CX access switches, where two ClearPass servers are used to implement AAA. Each switch has the two servers defined. A network engineer notices the following command configured on the AOS-CX switches: radius-server tracking user-name monitor password plaintext aruba123What is the purpose of this configuration?

Accepted Answer

Speed up the AAA authentication process

Answer

Each switch has the two servers defined. A network engineer notices the following command configured on the AOS-CX switches: radius-server tracking user-name monitor password plaintext aruba123What is the purpose of this configuration?

Answer

Implement replay protection for AAA messages

Answer

Define the account to implement downloadable user roles

Answer

Define the account to implement change of authorization

Question 5

A Senior Network Architect is designing a high-availability campus core solution for a financial institution. The design requires the use of two Aruba CX 8325 switches in a VSX cluster. The client requires that in the event of a split-brain scenario, the secondary switch must immediately shut down all its SVI interfaces to prevent routing loops, but the Keepalive link is routed through a separate management network. Which specific VSX configuration setting handles this SVI shutdown behavior during a split-brain event?

Accepted Answer

split-recovery

Answer

keepalive-shutdown

Answer

isl-protection

Answer

linkup-delay-timer

Question 6

An administrator is planning the subnet sizing for a new building that will utilize Dynamic Segmentation with User-Based Tunneling (UBT). There will be approximately 2000 users. All traffic will be tunneled back to a cluster of Aruba Gateways. What is a critical design consideration regarding the VLAN configuration on the access layer CX 6300 switches?

Accepted Answer

The user VLANs must exist on the Gateway but do not need to exist on the access switches.

Answer

The user VLANs must be configured on the access switches and added to the trunk uplink.

Answer

The access switches must have SVI interfaces configured for all user VLANs to act as the default gateway.

Answer

A dedicated transit VLAN must be configured for OSPF peering between the access switch and the Gateway.

Question 7

A network consultant is designing a migration plan from a legacy three-tier architecture to a collapsed core using Aruba CX 8360 switches. The current environment uses PVST+ with 500 VLANs. The new design will utilize MSTP. Which design decision ensures the smoothest interoperability during the migration phase?

Accepted Answer

Ensure the MSTP region root is also the root for the Common Spanning Tree (CST) to appear as a single bridge to PVST+.

Answer

Configure VRRP on the legacy switches to handle the spanning tree root bridge election.

Answer

Map all 500 VLANs to a single MSTP instance to match the single PVST+ instance.

Answer

Disable spanning tree on the boundary links and use LACP instead.

Question 8

You are configuring a VSX cluster on two CX 6400 switches. You have configured the Inter-Switch Link (ISL) on a 100GbE LAG. Which requirement regarding the ISL VLAN membership is mandatory for VSX synchronization to function correctly?

Accepted Answer

The ISL LAG must be a member of all VLANs that are extended across the VSX cluster.

Answer

The ISL LAG must only be a member of the dedicated Keepalive VLAN.

Answer

The ISL LAG must be configured as a routed interface with no VLAN membership.

Answer

The ISL LAG must be member of VLAN 1 only for control plane traffic.
