Which two commands are used to troubleshoot Layer 3 connectivity on an Aruba CX switch? (Select two)
- A . ping
- B . traceroute
- C . show vlan
- D . show clock
A, B
Explanation:
The ping command verifies connectivity to a remote device, while traceroute shows the path traffic takes, assisting in diagnosing network issues.
Which CLI command verifies the buffer utilization of network queues?
- A . show qos buffer statistics
- B . display queue depth
- C . show traffic queueing
- D . show interface buffer
A
Explanation:
The show qos buffer statistics command provides details on buffer usage, helping detect packet drops due to queue overflow.
Which CLI command enables IGMP snooping on an Aruba CX switch?
- A . ip igmp snooping enable
- B . multicast igmp snooping
- C . enable igmp-snooping
- D . switchport igmp enable
A
Explanation:
The ip igmp snooping enable command activates IGMP snooping, allowing switches to manage multicast traffic efficiently by forwarding packets only to subscribed receivers.
Which CLI command removes a misconfigured service-policy from an interface?
- A . no service-policy
- B . unset qos profile
- C . delete qos policy
- D . clear traffic settings
A
Explanation:
The no service-policy command removes all QoS rules applied to an interface, ensuring misconfigured traffic rules do not degrade performance.
Which CLI command limits the number of MAC addresses that can be learned on a port?
- A . port-security maximum 5
- B . mac-limit 5
- C . switchport max-mac 5
- D . set mac address-limit 5
A
Explanation:
The port-security maximum 5 command restricts the number of MAC addresses per port, preventing unauthorized devices from connecting to the network.
Which Aruba CX switch feature enables stacking multiple switches to operate as a single unit?
- A . Virtual Switching Framework (VSF)
- B . Virtual Switching Extension (VSX)
- C . Multi-Chassis Link Aggregation (MC-LAG)
- D . Dynamic Segmentation
A
Explanation:
VSF allows multiple switches to function as a single logical switch, improving scalability, redundancy, and simplified management.
Which two traffic classification methods are supported by Aruba CX QoS? (Select two)
- A . DSCP (Differentiated Services Code Point)
- B . 802.1p CoS (Class of Service)
- C . ARP Priority Tagging
- D . VLAN ID Prioritization
A, B
Explanation:
DSCP prioritizes Layer 3 traffic using IP headers, while 802.1p CoS assigns traffic priorities at Layer 2 based on VLAN tags, ensuring QoS policy enforcement across networks.
Which feature enables automated failover in Aruba CX core switches?
- A . Multi-Chassis Link Aggregation (MC-LAG)
- B . NetEdit
- C . Smart Rate Ports
- D . Checkpoint and Rollback
A
Explanation:
MC-LAG ensures failover protection by allowing links to multiple switches, avoiding single points of failure and enhancing redundancy in enterprise networks.
Which Aruba CX switch command is used to verify the stacking status of a VSF-enabled switch?
- A . show vsf
- B . show stacking
- C . show vsx status
- D . show system summary
A
Explanation:
The show vsf command displays stacking details, including member switches, priority, and role, ensuring proper operation of a VSF deployment.
Which CLI command removes a static route from an Aruba CX switch?
- A . no ip route 192.168.1.0/24
- B . delete route 192.168.1.0/24
- C . remove static route 192.168.1.0/24
- D . unset route 192.168.1.0/24
A
Explanation:
The no ip route command removes a previously configured static route, ensuring packets follow alternative paths via dynamic routing protocols.
