- A . aruba-central disable
- B . cloud-unregister
- C . telemetry disable
- D . no aruba-central
D
Explanation:
The no aruba-central command unlinks the switch from Aruba Central, stopping cloud-based monitoring and returning it to local management control.
Which Aruba CX switch series is optimized for high-performance data center leaf-spine architectures?
- A . Aruba CX 6300
- B . Aruba CX 6200
- C . Aruba CX 4100i
- D . Aruba CX 8400
D
Explanation:
The CX 8400 is designed for scalable, high-speed data center networks, supporting multi-terabit switching, VXLAN/EVPN, and deep buffer architectures.
Which CLI command configures a static MAC address on a specific interface?
- A . mac-address-table static 00:1A:2B:3C:4D:5E vlan 10 interface 1/1/1
- B . set mac static 00:1A:2B:3C:4D:5E vlan 10
- C . mac-address sticky 00:1A:2B:3C:4D:5E
- D . port-security static-mac 00:1A:2B:3C:4D:5E
A
Explanation:
The mac-address-table static command binds a MAC address to an interface, ensuring devices always receive the same VLAN assignment for security and consistency.
Which Aruba CX switch series provides high-performance core switching in a modular chassis?
- A . Aruba CX 6200
- B . Aruba CX 8400
- C . Aruba CX 8325
- D . Aruba CX 9300
B
Explanation:
The Aruba CX 8400 is a modular core switch, designed for enterprise networks requiring scalability, multi-terabit performance, and VXLAN support for advanced network segmentation.
Which CLI command displays the operational state of the switch CPU and memory usage?
- A . show system resources
- B . display cpu status
- C . show system utilization
- D . show process load
A
Explanation:
The show system resources command helps diagnose high CPU or memory usage, ensuring switch performance is not degraded due to excessive processing loads.
Which Aruba CX switch series is optimized for IoT and edge networking in harsh environments?
- A . Aruba CX 10000
- B . Aruba CX 6200
- C . Aruba CX 4100i
- D . Aruba CX 9300
C
Explanation:

Which two overlay technologies are supported on Aruba CX switches? (Select two)
- A . EVPN
- B . VXLAN
- C . GRE
- D . MPLS
A, B
Explanation:
EVPN (Ethernet VPN) and VXLAN provide network virtualization, enabling multi-tenant segmentation and scalable Layer 2 overlays over Layer 3 networks.
Which CLI command configures a switch to automatically recover an err-disabled port due to security violations?
- A . port-security violation recovery enable
- B . errdisable recovery cause security-violation
- C . errdisable auto-recover security
- D . port-recovery security enable
B
Explanation:
The errdisable recovery cause security-violation command enables automatic recovery, allowing the port to re-enable after a timeout instead of manual intervention.
Which CLI command displays QoS queue statistics on an Aruba CX switch?
- A . show qos queue statistics
- B . display qos queues
- C . show traffic-queue usage
- D . show qos interface queue
A
Explanation:
The show qos queue statistics command provides insight into queue utilization and dropped packets, helping administrators fine-tune QoS policies for performance optimization.
Which CLI command applies a QoS policy to an interface?
- A . service-policy input qos-policy-1
- B . qos apply qos-policy-1
- C . traffic-policy qos-policy-1
- D . apply qos-profile qos-policy-1
A
Explanation:
The service-policy input command applies a predefined QoS policy to an interface, ensuring traffic classification and prioritization are enforced at the port level.
