Refer to the exhibit. An engineer plans to upgrade the Cisco ACI fabric. Leaf1 and Leaf2 are deployed in a VPC. The fabric is peering with R1 using BGP protocol. Which two actions upgrade the fabric nondisruptively? (Choose two.)

To upgrade the Cisco ACI fabric nondisruptively, the following actions should be taken: Configure the Graceful upgrade option as it ensures minimal disruption during the upgrade process. Enable the Graceful Insertion and Removal option as it helps in maintaining operational stability and ensures that the leafs can be inserted and removed gracefully without affecting ongoing traffic.
Only correct answer is A….D is not correct unless it is a typo, putting a switch in maintenance does not help upgrading it.
A and D: Graceful Insertion and Removal, cannot be used for Upgrades, it is meant for isolation, debugs...
Maintenance mode is not used for update

Therefore, performing a firmware upgrade for a switch in this state is not supported, since it may fail or may get stuck in an incomplete status indefinitely if you attempt to perform a firmware upgrade on it while it is in this state.
