Which Aruba CX feature allows segmentation of traffic within the same Layer 2 domain?
- A . EVPN/VXLAN
- B . Multi-Chassis Link Aggregation (MC-LAG)
- C . Virtual Switching Extension (VSX)
- D . Zero Touch Provisioning (ZTP)
A
Explanation:
EVPN/VXLAN extends Layer 2 segmentation over Layer 3 networks, enabling multi-tenancy, traffic isolation, and scalability in data center and enterprise deployments.
Which two PIM modes are supported on Aruba CX switches? (Select two)
- A . PIM Sparse Mode (PIM-SM)
- B . PIM Dense Mode (PIM-DM)
- C . PIM Hybrid Mode
- D . PIM Static Mode
A, B
Explanation:
PIM-SM optimizes multicast distribution by only forwarding traffic to explicitly requested receivers, while PIM-DM floods multicast traffic and prunes unused paths.
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 Aruba CX switch series is optimized for high-density, low-latency data center networking?
- A . Aruba CX 6200
- B . Aruba CX 9300
- C . Aruba CX 4100i
- D . Aruba CX 6300
B
Explanation:
The CX 9300 provides low-latency switching, deep buffering, and high-speed interconnects, making it ideal for high-performance data center deployments.
You suspect asymmetric routing on VXLAN-EVPN collapsed core/aggregation switches running BGP EVPN.
Which three commands or utilities help confirm the issue?
- A . show vxlan vtep mac-ip
- B . traceroute vrf <name> <destination>
- C . show bgp evpn route-type 2
- D . show ip flow export
- E . show l2-vpn database
A, B, C
Explanation:
The VTEP MAC-IP table validates correct endpoint learning; traceroute inside the tenant VRF reveals unequal forward/reverse paths; Route-Type 2 (MAC/IP) advertisements confirm whether both directions of host reachability exist. Flow-export stats and generic L2-VPN DBs do not directly surface EVPN asymmetry.
Which CLI command configures an Aruba CX switch to use Syslog for remote logging?
- A . logging host 192.168.1.100
- B . syslog enable 192.168.1.100
- C . enable remote logging
- D . log-server 192.168.1.100
A
Explanation:
The logging host command configures a Syslog server, allowing centralized log collection for network event monitoring, security analysis, and troubleshooting.
Which two actions help remediate a duplex mismatch issue? (Select two)
- A . Configure both sides to auto-negotiate
- B . Manually set both ports to the same duplex mode
- C . Change one end to half-duplex and the other to full-duplex
- D . Enable VLAN trunking on both ends
A, B
Explanation:
Duplex mismatches cause packet loss and slow performance, so setting both interfaces to the same mode―either auto-negotiation or manual configuration―ensures proper communication.
Which CLI command displays active multicast routing entries on an Aruba CX switch?
- A . show ip mroute
- B . show multicast routes
- C . display multicast routing
- D . show pim routes
A
Explanation:
The show ip mroute command lists multicast routing table entries, showing group addresses, source addresses, and interface mappings for multicast traffic forwarding.
Which CLI command configures a static multicast route on an Aruba CX switch?
- A . ip mroute 239.1.1.1 192.168.1.1
- B . multicast route 239.1.1.1 via 192.168.1.1
- C . set multicast static 239.1.1.1
- D . pim static-route 239.1.1.1
A
Explanation:
The ip mroute command manually defines a multicast forwarding path, ensuring predictable multicast traffic behavior without requiring dynamic routing protocols.
Which feature in Aruba CX prevents misconfigurations by validating network changes before
deployment?
- A . Aruba NetEdit
- B . Virtual Switching Extension (VSX)
- C . Checkpoint and Rollback
- D . Zero Touch Provisioning (ZTP)
A
Explanation:
NetEdit continuously validates network configurations, ensuring consistency, security compliance, and automated rollback in case of errors.
