A data center has two Juniper EX4600 switches configured as a virtual chassis. The network team needs to perform a software upgrade on the master switch. They want to minimize downtime and ensure that the backup switch takes over seamlessly. What is the best approach?

Upgrade both switches simultaneously.

Reboot the master switch immediately to trigger failover, then upgrade the backup.

Upgrade the backup switch first, then reboot the master to trigger failover.

Use the 'request system software add' command on the master only.

An organization is deploying a chassis cluster on two QFX5100 switches. They need to ensure that the cluster can detect a failure of the primary node even if the control link goes down. What should be configured?

Use the fabric link for control traffic.

Set the failover threshold to a lower value.

Enable heartbeat mode on the control link.

Configure a redundant control link.

Which issue is commonly indicated by the 'show chassis cluster status' command displaying 'Ineligible' for a node?

The node is not participating in the cluster due to a configuration or hardware problem

The node is synchronizing its configuration with the active node

The node is currently active and handling traffic

The node has a lower priority than the active node

An organization is setting up a virtual chassis with three EX4300 switches. They want to ensure that the switch with the highest priority becomes the master. What must be configured?

Configure the switches in a ring topology to ensure proper election.

Use the 'request virtual-chassis reelect' command to force the desired switch to become master.

Set the role of each switch using the 'set virtual-chassis role' command.

Set the mastership priority on each switch using the 'set virtual-chassis mastership-priority' command.
