Which CLI command enables Power over Ethernet (PoE) on an Aruba CX switch port?
- A . power-over-ethernet enable
- B . poe power enable
- C . interface 1/1/1 poe enable
- D . show poe interface
A
Explanation:
The power-over-ethernet enable command allows the switch port to provide power, supporting devices such as IP phones, cameras, and access points.
Which two Aruba CX switch features are essential for securing and segmenting user traffic? (Select two)
- A . Dynamic Segmentation
- B . EVPN/VXLAN
- C . VSF (Virtual Switching Framework)
- D . Intelligent Power Management
A, B
Explanation:
Dynamic Segmentation integrates with ClearPass for policy-based VLAN enforcement, while EVPN/VXLAN allows scalable network segmentation across Layer 2 and Layer 3 domains.
Which CLI command enables QoS globally on an Aruba CX switch?
- A . qos enable
- B . traffic-classification enable
- C . enable qos
- D . apply qos global
A
Explanation:
The qos enable command activates QoS features on the switch, allowing traffic classification, prioritization, and congestion management to improve network performance.
Which command is used to verify the currently assigned IP address on a VLAN interface?
- A . show vlan id
- B . show ip interface brief
- C . show vlan ip address
- D . show system
B
Explanation:
The show ip interface brief command lists all interfaces and their assigned IP addresses, ensuring proper Layer 3 connectivity.
Which CLI command removes an incorrect OSPF area configuration on an Aruba CX switch?
- A . no router ospf area
- B . delete ospf process
- C . unset ospf area
- D . clear ospf route
A
Explanation:
The no router ospf area command removes an incorrectly assigned OSPF area, ensuring OSPF neighbors form correctly within the correct routing domain.
Which Aruba CX feature allows intelligent event-driven automation for network troubleshooting?
- A . Checkpoint and Rollback
- B . Virtual Switching Framework (VSF)
- C . Network Analytics Engine (NAE)
- D . Aruba NetEdit
C
Explanation:
NAE provides real-time event correlation and automation, enabling proactive monitoring, anomaly detection, and self-healing network operations.
Which CLI command displays the currently configured Syslog servers on an Aruba CX switch?
- A . show logging host
- B . show syslog servers
- C . display logging remote
- D . show log configuration
A
Explanation:
The show logging host command lists all configured Syslog servers, helping administrators verify logging configurations and troubleshoot log transmission issues.
Which two commands are required to enable and configure a switch port for access mode? (Select two)
- A . interface 1/1/1
- B . switchport mode access
- C . set vlan access 10
- D . enable port-security
A, B
Explanation:
The interface command selects the port, while switchport mode access ensures it functions as an access port for a specific VLAN.
Which Aruba Central feature enables firmware updates across multiple CX switches simultaneously?
- A . Network Analytics Engine (NAE)
- B . Firmware Compliance Groups
- C . Smart Rate Ports
- D . Multi-Chassis Link Aggregation (MC-LAG)
B
Explanation:
Firmware Compliance Groups automate firmware updates, ensuring consistent software versions and reducing manual upgrade complexity.
Which two QoS mechanisms help prevent congestion on an Aruba CX switch? (Select two)
- A . Weighted Fair Queuing (WFQ)
- B . Random Early Detection (RED)
- C . ARP Rate Limiting
- D . DNS Load Balancing
A, B
Explanation:
WFQ ensures fair bandwidth distribution across multiple traffic flows, while RED proactively drops low-priority packets to prevent congestion before queues overflow.
