HPE Aruba Certified Network Security Expert (ACNSX) — Question 32
An administrator of a company has concerns about upgrading the access layer switches. The users rely heavily on wireless and VoIP telephony. Which is the best recommendation to ensure a short downtime for the users during upgrading the access layer switches?
Answer options
- A. Install the in-service software upgrade (ISSU) feature with clustering enabled
- B. Install AOS-CX 6300 or 6400 switches with always-on POE
- C. Implement VSF on the AOS-CX access switches
- D. Implement VSX on the AOS-CX access switches
Correct answer: B
Explanation
The best choice is B because AOS-CX 6300 or 6400 switches with always-on POE ensure continuous power to devices, reducing downtime during upgrades. Option A, while it addresses software upgrades, may still lead to interruptions. Options C and D involve configurations that do not specifically ensure minimized downtime for wireless and VoIP services.
