A Virtual Chassis has three members. One member needs to be replaced due to a hardware fault. The administrator wants to minimize traffic disruption. Which procedure should be followed?

Remove the faulty member's configuration from the master and then power off the switch.

Reboot the entire Virtual Chassis to remove the faulty member.

Power off the faulty member, disconnect it, and then power on the replacement switch after connecting it to the VCP ports.

Use the request system reboot member command on the faulty member.

Which command is used to configure the virtual management interface (VME) on a Juniper Virtual Chassis?

set interfaces vcp-0 unit 0 family inet address

set interfaces vme unit 0 family inet address

set virtual-chassis management-interface ip

A Virtual Chassis is configured with GRES and NSR. The master switch's control plane becomes unresponsive, but the data plane continues to forward traffic. The backup switch detects the failure. What is the expected behavior?

Routing protocols reconverge, causing a brief traffic interruption.

Traffic forwarding stops until the backup switch reboots.

The Virtual Chassis splits into two separate switches.

The backup switch takes over as master, and traffic forwarding continues without interruption.

An administrator needs to perform a software upgrade on a Virtual Chassis with two members. The administrator wants to minimize downtime and ensure that the control plane remains available during the upgrade. Which approach should be used?

Upgrade both members simultaneously using the request system software add command on the master.

Use the request virtual-chassis upgrade command to upgrade all members at once.

Upgrade the backup member first, then fail over to it and upgrade the master.

Reboot the entire Virtual Chassis and then install the new software.

A Virtual Chassis has four members. The administrator needs to remove member 3 from the Virtual Chassis permanently. Which command should be used on the master switch?

request virtual-chassis delete member 3

request virtual-chassis renumber member 3 to 0
