- Question 1Intermediate
Architecture · VSX Upgrades
An administrator is designing a high-availability architecture using Aruba CX 8325 switches in a VSX cluster. The core requirement is to ensure that during a software upgrade of the VSX cluster, there is minimal downtime and zero packet loss for connected dual-homed servers. Which upgrade mechanism should the administrator utilize to meet these strict requirements?
Show answer & explanation
Correct answer: C
VSX Live Upgrade (VSX-LU) is the automated process designed specifically for VSX clusters. It upgrades the members one by one, ensuring traffic is steered away from the rebooting member, providing a near-zero downtime experience for dual-homed endpoints. FSU is a different mechanism not specific to the orchestrated cluster upgrade workflow.

Automation · NAE Troubleshooting
You are troubleshooting a customized Network Analytics Engine (NAE) script on an Aruba CX switch. The script is supposed to trigger an alert when CPU utilization exceeds 90%. However, the script status shows 'Critical Error' and is not collecting data. Reviewing the agent logs, you see a 'Sandbox memory limit exceeded' error. What is the most likely cause of this issue?
Show answer & explanation
Correct answer: D
NAE agents run in sandboxed containers with strict memory limits. If a script attempts to monitor an excessive number of URIs (wildcards) or stores too much historical data in local variables without flushing, it will hit the memory cap and crash. The solution is to optimize the script's scope.
- Question 3Intermediate
Architecture · VSX Failure Scenarios
A network engineer is configuring a VSX cluster with Active Gateway. The customer requires that the gateway IP addresses remain reachable even if the VSX Inter-Switch Link (ISL) fails but the Keepalive link remains up. Which specific VSX feature helps mitigate split-brain scenarios by shutting down non-critical links on the secondary member?
Show answer & explanation
Correct answer: C
When the ISL fails but the Keepalive is active, the secondary switch detects a split-brain condition. Split-recovery mode (enabled by default) shuts down all VSX LAGs and SVI interfaces on the secondary member to prevent loops and duplicate IP addresses, keeping the primary active.
- Question 4Beginner
Routing · OSPF Configuration
In an Aruba CX environment running OSPF, you need to ensure that a specific core switch is always preferred as the Designated Router (DR) for the broadcast segment on VLAN 10. Which configuration command achieves this on Interface VLAN 10?
Show answer & explanation
Correct answer: A
Setting the OSPF priority to the maximum value of 255 ensures that the router will win the DR election against any other router with a lower priority. The default priority is 1.
- Question 5Intermediate
Security · Dynamic Segmentation
Which of the following statements regarding the implementation of Dynamic Segmentation with User-Based Tunneling (UBT) on Aruba CX switches is TRUE?
Show answer & explanation
Correct answer: A
UBT on CX switches requires a Reserved VLAN to be configured. This VLAN is used internally for the GRE tunnel termination on the switch side before traffic is encapsulated to the Gateway. It must not be assigned to any physical port.
- Question 6Intermediate
Multicast · PIM-SM
A financial institution requires strict multicast control. They are implementing PIM-SM (Sparse Mode) on their Aruba CX core. They want to ensure that a specific core switch is always selected as the Rendezvous Point (RP) for the multicast group 239.0.0.0/8. Which configuration approach provides the most dynamic and redundant method for distributing this RP information?
Show answer & explanation
Correct answer: C
BSR is a standard dynamic mechanism where Candidate-RPs announce themselves to the BSR, which then disseminates the RP-Set to all PIM routers. This avoids manual static RP configuration on every router and supports redundancy.
- Question 7Beginner
Management · NetEdit
You are utilizing NetEdit to manage a fleet of Aruba CX switches. You need to verify that a new configuration change adheres to corporate policy before deploying it. Which NetEdit feature allows you to simulate the configuration validation against defined rules without actually pushing the config to the devices?
Show answer & explanation
Correct answer: C
In NetEdit, creating a 'Plan' allows you to edit configurations. The 'Validate' step checks the proposed changes against syntax correctness and internal conformance rules (policies) before the 'Deploy' phase initiates the actual push.
- Question 8AdvancedSelect 2
Routing · BGP Attributes
A customer is deploying a Multi-Fabric solution using BGP EVPN on Aruba CX 8325 switches. They need to filter specific routes from being advertised between BGP peers to control traffic flow. Which TWO BGP attributes are most commonly manipulated in Route Maps to influence path selection? (Select TWO)
Show answer & explanation
Correct answers: A, D
Local Preference is used to influence outbound traffic flow from the local AS (higher value preferred).
AS Path Prepending makes a path look longer, thus less desirable, influencing inbound traffic flow from external peers. Both Local Pref and AS Path are standard methods for path manipulation in BGP.
