300-425 Question 34
Select 3A network engineer is tasked with upgrading the software image on a set of Cisco Access Points (APs) managed by a Cisco WLC (Wireless LAN Controller). The engineer decides to use the Smart AP Image Upgrade feature to perform this task. Which of the following statements about the Smart AP Image Upgrade process are correct?
- A
The Smart AP Image Upgrade process minimizes network downtime by upgrading APs in batches.
- B
Smart AP Image Upgrade requires all APs to reboot simultaneously to complete the upgrade process.
- C
During the Smart AP Image Upgrade, traffic handling continues on the APs that are not being upgraded.
- D
The feature allows the APs to download the new image directly from Cisco's cloud servers.
- E
The WLC manages the AP image upgrade process and ensures synchronization of the AP software version.
Show answer and explanation
Correct answers: A, C, E
Explanation
The Smart AP Image Upgrade feature is designed to streamline the process of upgrading software on Cisco Access Points while minimizing network downtime. It achieves this by upgrading APs in batches and ensuring traffic handling continues on APs not currently being upgraded. The Wireless LAN Controller (WLC) plays a central role in managing the upgrade process, distributing the image and ensuring synchronization. This approach ensures minimal disruption to network operations while maintaining a consistent software version across APs.
- A. Correct.
Correct: Smart AP Image Upgrade minimizes downtime by upgrading APs in groups or batches, ensuring that some APs remain operational while others are being updated.
- B. Incorrect.
Incorrect: Smart AP Image Upgrade does not require all APs to reboot simultaneously. It is specifically designed to avoid this and reduce overall network disruption.
- C. Correct.
Correct: APs not currently being upgraded continue to handle traffic, ensuring network availability during the upgrade process.
- D. Incorrect.
Incorrect: Smart AP Image Upgrade does not involve APs downloading images directly from Cisco's cloud servers. Instead, the WLC typically distributes the software image.
- E. Correct.
Correct: The WLC centrally manages the Smart AP Image Upgrade process, ensuring that all APs are synchronized to the correct software version.
