Which feature of Aruba CX ensures seamless failover between two core switches in an enterprise network?
- A . Multi-Chassis Link Aggregation (MC-LAG)
- B . Zero Touch Provisioning (ZTP)
- C . Virtual Switching Extension (VSX)
- D . Network Analytics Engine (NAE)
C
Explanation:
VSX enables active-active redundancy between two core switches, ensuring seamless failover, independent control planes, and minimal downtime in case of failure.
Which Aruba CX switch series is best suited for a multi-tenant cloud environment?
- A . Aruba CX 6200
- B . Aruba CX 9300
- C . Aruba CX 8400
- D . Aruba CX 10000
D
Explanation:
The CX 10000 integrates Pensando SmartNIC, enabling distributed firewalling and microsegmentation, making it ideal for cloud data centers and multi-tenant architectures.
Which CLI command enables API access on an Aruba CX switch for automation?
- A . https-server rest enable
- B . enable api access
- C . set rest-api enable
- D . apply automation api
A
Explanation:
The https-server rest enable command activates the REST API, allowing integration with automation tools such as Ansible, Python scripts, and third-party management platforms.
Which CLI command resets all learned dynamic ARP entries on an Aruba CX switch?
- A . clear ip arp
- B . reset arp table
- C . delete dynamic arp
- D . unset arp cache
A
Explanation:
The clear ip arp command removes all dynamically learned ARP entries, helping resolve stale ARP cache issues that can cause connectivity failures.
Which CLI command removes an incorrectly configured BPDU Guard setting from an interface?
- A . no spanning-tree bpdu-guard
- B . unset bpdu-guard
- C . clear spanning-tree port
- D . disable bpdu security
A
Explanation:
The no spanning-tree bpdu-guard command disables BPDU Guard on a port, allowing switches to communicate in networks where BPDU Guard was mistakenly applied.
Which CLI command verifies the number of MAC addresses learned on a specific port?
- A . show port-security interface 1/1/1
- B . show mac-table interface 1/1/1
- C . show mac-learned 1/1/1
- D . show interface mac
A
Explanation:
The show port-security interface 1/1/1 command displays MAC addresses associated with a port, helping administrators enforce and troubleshoot security policies.
Which two Aruba CX switch series are best suited for industrial environments requiring ruggedized hardware? (Select two)
- A . Aruba CX 6200
- B . Aruba CX 4100i
- C . Aruba CX 8325
- D . Aruba CX 8400
B, D
Explanation:
The CX 4100i is specifically designed for harsh environments, while the CX 8400 offers modular, high-performance switching for mission-critical networks.
Which two security features prevent unauthorized MAC address spoofing on an Aruba CX switch? (Select two)
- A . MAC lockdown
- B . Dynamic ARP Inspection (DAI)
- C . DHCP snooping
- D . BPDU Guard
A, B
Explanation:
MAC lockdown restricts which MAC addresses can connect to a port, while DAI inspects ARP packets to prevent spoofing attacks that manipulate IP-to-MAC mappings.
Which CLI command removes a misconfigured TACACS+ authentication server?
- A . no tacacs-server host
- B . delete tacacs
- C . unset tacacs-server
- D . clear tacacs setting
A
Explanation:
The no tacacs-server host command removes a misconfigured TACACS+ server entry, ensuring authentication requests are sent to the correct server.
Which CLI command configures an Aruba CX switch to act as the STP root bridge?
- A . spanning-tree root primary
- B . set spanning-tree primary
- C . stp root enable
- D . enable root bridge
A
Explanation:
The spanning-tree root primary command forces the switch to become the root bridge, lowering its priority to win STP elections and control path selection.
