HPE Aruba Certified Mobility Professional (ACMP) — Question 88

A company requires AOS-Switches at the campus core. The switches:
✑ Will act as the default gateways for several campus VLANs
✑ Must provide redundancy for their services and tolerate the loss of a link or an entire switch
✑ Must recover from the failure of one of the switches within a second or less
VRRP and MSTP are proposed to meet these requirements. What is an issue with this proposal?

Answer options

• A. VRRP provides redundancy against lost links but not a failed switch
• B. VRRP provides routing redundancy but not default gateway redundancy
• C. VRRP does not interoperate with MSTP
• D. VRRP takes longer than a second to fail over

Correct answer: D

Explanation

The correct answer is D because VRRP does not meet the requirement of recovering from a switch failure within one second. Options A and B are incorrect since VRRP does provide redundancy for lost links and can act as a default gateway. Option C is also incorrect as VRRP can interoperate with MSTP.
