HPE Aruba Certified Professional (ACP) – SD-WAN — Question 40

How would you explain the functionality of an HPE Aruba Networking VSX inter-switch link protocol (ISLP)?

Answer options

• A. ISLP utilized the keepalive L3 connectivity to synchronize switch configuration.
• B. ISLP requires a Routed Only Port to be enabled for VSX.
• C. ISLP periodically synchronizes protocol states, such as RPVST+.
• D. ISLP periodically synchronizes protocol states, such as LACP.

Correct answer: D

Explanation

The correct answer is D because ISLP is designed to synchronize protocol states, specifically including Link Aggregation Control Protocol (LACP). Options A and B are incorrect as they do not accurately describe the purpose of ISLP, and C is incorrect because it mentions RPVST+, which is not the primary focus of ISLP.
