HPE Aruba Certified Network Security Expert (ACNSX) — Question 12

A network administrator is attempting to troubleshoot a connectivity issue between a group of users and a particular server. The administrator needs to examine the packets over a period of time from their desktop; however, the administrator is not directly connected to the AOS-CX switch involved with the traffic flow.
What is correct regarding the ERSPAN session that needs to be established on an AOS-CX switch? (Choose two.)

Answer options

• A. On the source AOS-CX switch, the destination specified is the switch to which the administrator's desktop is connected
• B. On the source AOS-CX switch, the destination specified is the administrator's desktop
• C. The encapsulation protocol used is GRE
• D. The encapsulation protocol used is VXLAN
• E. The encapsulation protocol is UDP

Correct answer: A, C

Explanation

Option A is correct because the destination of the ERSPAN session should be the switch that connects to the administrator's desktop. Option C is also correct, as ERSPAN uses GRE encapsulation for transporting packets. Options B, D, and E are incorrect since they do not accurately describe the ERSPAN session's destination or encapsulation protocol.
