300-425 Question 35
Single answerYou are managing a Cisco wireless network with multiple access points (APs) connected to a Cisco Catalyst 9800 Series Wireless LAN Controller (WLC). You need to upgrade the AP image across the network, but you want to minimize downtime and disruptions to client connections. Which feature of the Smart AP image upgrade process helps achieve this goal?
- A
Rolling AP upgrade
- B
Parallel upgrade across all APs
- C
Pre-download of the new image to APs
- D
Manual reboot of each AP after the upgrade
Show answer and explanation
Correct answer: C
Explanation
The Smart AP image upgrade process includes the pre-download feature, which ensures that the new image is sent to APs prior to the actual upgrade. By pre-downloading the image, the APs can minimize downtime and client disruptions during the upgrade process, as the only remaining step is a quick reboot to apply the new image.
- A. Incorrect.
This is incorrect because a rolling AP upgrade involves upgrading APs one by one, which may still cause some disruption to client connections during the upgrade process.
- B. Incorrect.
This is incorrect because a parallel upgrade forces all APs to upgrade simultaneously, which can lead to significant downtime for the entire network.
- C. Correct.
This is correct because the pre-download feature allows the new image to be downloaded to the APs in advance, reducing upgrade time and minimizing disruptions when the APs reboot to apply the new image.
- D. Incorrect.
This is incorrect because manually rebooting each AP after the upgrade adds unnecessary manual effort and increases downtime compared to the automated reboot process in Smart AP image upgrades.
