- Question 1Intermediate
Architecture · High Availability
A network administrator is designing a high-availability solution for a campus core using Aruba CX 8325 switches. The design requires that both switches maintain independent control planes to allow for live upgrades without downtime, while presenting a unified Layer 2 interface to downstream access switches. Which technology should be deployed to meet these specific requirements?
Show answer & explanation
Correct answer: D
VSX (Virtual Switching Extension) is designed for the Aruba CX platform to provide high availability with independent control planes. This allows for live software upgrades (VSX Live Upgrade) where traffic continues to flow through one peer while the other upgrades, unlike VSF which shares a single control plane.

Layer 3 Routing · VLAN Interfaces
An administrator needs to configure a new VLAN interface on an Aruba CX 6300 switch to act as the default gateway for the 'Finance' department. The subnet is 10.20.10.0/24 and the gateway IP should be the last usable address in the subnet. Which set of commands correctly configures this interface?
Show answer & explanation
Correct answer: A
In ArubaOS-CX, Layer 3 VLAN interfaces are configured using 'interface vlan X'. The last usable address in a /24 subnet (10.20.10.0-10.20.10.255) is .254. The 'no shutdown' command is often required to ensure the administrative state is up, although it may be up by default depending on the specific version and context, explicitly enabling it is best practice.
- Question 3Advanced
Architecture · AOS-CX Database
You are troubleshooting an issue where an Aruba CX switch is not receiving configuration updates from NetEdit. You suspect an issue with the REST API access or the database synchronization. In the ArubaOS-CX architecture, which specific database is responsible for holding the current operating state and configuration of the system that NetEdit interacts with?
Show answer & explanation
Correct answer: D
ArubaOS-CX is built on a microservices architecture centered around the OVSDB (Open vSwitch Database). This state database holds all configuration and status information. NetEdit and other tools interact with the system via the REST API, which reads from and writes to this central OVSDB.
- Question 4Intermediate
Stacking · VSF Troubleshooting
A technician has replaced a failed switch in a VSF stack. After the new switch boots, it does not automatically join the stack. The administrator verifies that the VSF links are connected correctly. What is the most likely cause of this issue?
Show answer & explanation
Correct answer: B
In VSF (Virtual Switching Framework), simply connecting cables is often not enough if auto-stacking isn't configured or if the replacement unit isn't clean. The new member usually needs to be provisioned (assigned a member ID) on the Commander, or auto-stacking features must be correctly set up for it to join automatically.

Layer 2 Switching · Spanning Tree
Select TWO reasons why an administrator would choose to deploy Multi-Instance Spanning Tree (MSTP) over Rapid Per-VLAN Spanning Tree (RPVST+) in a large campus network. (Select TWO)
Show answer & explanation
Correct answers: B, C
MSTP maps multiple VLANs to a single instance, significantly reducing the number of BPDU calculations and CPU overhead compared to RPVST+, which runs a separate instance for every VLAN.
Because MSTP uses fewer instances, it sends fewer BPDUs across trunk links compared to RPVST+, which sends a BPDU for every VLAN on the trunk.
- Question 6Intermediate
Architecture · VSX Synchronization
True or False: In an Aruba CX VSX pair, the configuration synchronization feature automatically pushes all configuration changes from the Primary to the Secondary peer by default, including interface descriptions and IP addresses.
Show answer & explanation
Correct answer: B
VSX synchronization is selective. It does not blindly sync everything. Specific features (like VLANs, ACLs, policies) must be explicitly allowed for sync, and unique interface configurations (like IP addresses on routed ports or descriptions) are typically maintained separately or require specific VSX-sync commands. It is not an 'all-or-nothing' full config push.
- Question 7Beginner
Layer 1/2 · Interface Management
You are configuring a new Aruba CX switch and need to verify the link status and speed of interface 1/1/1. Which command provides the most concise summary of the interface's physical state, speed, and duplex mode?
Show answer & explanation
Correct answer: C
The 'show interface brief' command displays a summary table of all interfaces, including their Admin State, Link State, Speed, and Duplex mode. 'show interface 1/1/1' gives detailed stats but is not a concise summary.
- Question 8Intermediate
Management · NetEdit
An administrator is using NetEdit to deploy a configuration change to 50 switches simultaneously. NetEdit detects that three of the switches have a configuration syntax error in the proposed plan. What is the default behavior of NetEdit in this scenario?
Show answer & explanation
Correct answer: B
NetEdit emphasizes validation and consistency. If a plan contains validation errors (syntax issues) for any device in the selected group, the 'Deploy' button is typically disabled or the process stops to prevent partial/broken states across the network fabric. The errors must be fixed in the plan before deployment.
