Which Aruba CX feature allows automatic switch provisioning in remote branch offices?
- A . Network Analytics Engine (NAE)
- B . Aruba NetEdit
- C . Zero Touch Provisioning (ZTP)
- D . Multi-Chassis Link Aggregation (MC-LAG)
C
Explanation:
ZTP automates switch deployment by downloading configurations and firmware updates, enabling hands-free provisioning in remote locations without manual intervention.
Which CLI command configures a trust boundary for incoming traffic based on DSCP values?
- A . qos trust dscp
- B . apply trust-dscp
- C . traffic trust dscp
- D . qos enforce dscp
A
Explanation:
The qos trust dscp command ensures DSCP-marked traffic is honored without modification, allowing end-to-end traffic prioritization in a QoS-enabled network.
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.
While capturing packets on an Aruba 6300M you must verify correct DSCP-to-queue mapping and confirm that IEEE 802.1X re-authentication events include EAPOL-Key MIC validation.
Which three tools/commands provide this information?
- A . show qos pfc-cos-queue-map
- B . show interface queue statistics
- C . SPAN session to an off-box analyzer
- D . packet-capture filter "ether proto 0x888e"
- E . show port-access authenticator statistics detail
B, C, D
Explanation:
Queue statistics show DSCP mappings in real time; a SPAN session plus filtered capture decodes EAPOL-Key MIC fields; authenticators detail doesn’t expose MIC status, and PFC COS maps are for lossless Ethernet, not DSCP-to-queue verification.
Which CLI command verifies active VXLAN remote VTEPs?
- A . show vxlan remote vtep
- B . show vxlan vtep
- C . display vxlan endpoints
- D . show vxlan peers
B
Explanation:
The show vxlan vtep command displays the remote VTEPs, listing tunnel status, remote IPs, and VXLAN mappings for overlay networking.
Which two Aruba CX switch features help in designing a high-availability core network? (Select two)
- A . VSX (Virtual Switching Extension)
- B . Checkpoint and Rollback
- C . Smart Rate Ports
- D . EVPN/VXLAN
A, B
Explanation:
VSX provides active-active redundancy at the core layer, while Checkpoint and Rollback ensures quick recovery from misconfigurations, maintaining high availability and resiliency.
Which two Link Aggregation Control Protocol (LACP) modes are supported on Aruba CX switches? (Select two)
- A . Passive
- B . Static
- C . Active
- D . Auto
A, C
Explanation:
LACP supports active mode, where the switch actively negotiates a link, and passive mode, where it waits for LACP negotiation requests.
Which two CLI commands enable per-VLAN STP configurations? (Select two)
- A . spanning-tree vlan 10 priority 4096
- B . stp vlan 10 root primary
- C . spanning-tree 10 priority 8192
- D . vlan 10 spanning-tree mode rstp
A, B
Explanation:
The spanning-tree vlan command sets VLAN-specific STP priorities, ensuring customized loop prevention for different VLANs in a network.
Which Aruba CX feature simplifies multi-device configurations across a large enterprise network?
- A . Zero Touch Provisioning
- B . Aruba NetEdit
- C . Dynamic Segmentation
- D . VSX
B
Explanation:
Aruba NetEdit provides automated configuration validation and deployment, ensuring consistency across multiple CX switches in large-scale environments.
Which VSF feature allows a member switch to continue forwarding new PoE power requests even if the commander fails?
- A . MAD LACP
- B . Distributed PoE Arbiter
- C . Orphan-port safeguard
- D . Priority-based power management
B
Explanation:
With Distributed PoE Arbiter enabled, standby members can honor PoE negotiations autonomously, ensuring power continuity despite commander loss.
