NEW QUESTION # 47
You are deploying a pair of VSX switches parallel to some existing HPE Comware switches. You would like to configure a common first-hop redundancy protocol as part of your migration strategy. Which of these would be suitable?
- A. HSRP
- B. VRRP
- C. Active Forwarding
- D. Active Gateway
Answer: B
Explanation:
When deploying HPE Aruba VSX switches parallel to existing HPE Comware switches, choosing a first-hop redundancy protocol compatible with both platforms is essential. VRRP (Virtual Router Redundancy Protocol) is widely supported across multiple vendors and is suitable for multi-vendor environments.
HSRP is Cisco proprietary and not supported on Aruba Comware or CX.
Active Forwarding and Active Gateway are Aruba VSX internal mechanisms, not standard first-hop redundancy protocols.
VRRP provides seamless failover and is supported in Comware and Aruba CX platforms.
Thus, VRRP is the suitable choice.

Based on the output, which Local Priority (LP) value will be applied to an incoming packet from interface 2/1
/39 marked with DSCP 46 and CoS 7?
- A. Local Priority 0
- B. Local Priority 1
- C. Local Priority 7
- D. Local Priority 5
Answer: B
