A data center uses a Virtual Chassis with three switches. The network team needs to perform a software upgrade on the Virtual Chassis with minimal disruption to traffic. Which approach should they use?

Upgrade the linecard switches first, then the master and backup

Upgrade the backup switch first, then perform a graceful switchover to make it master, and upgrade the original master

Upgrade the master switch first, then reboot the entire Virtual Chassis

Upgrade all switches simultaneously using the nonstop software upgrade (NSSU) feature

A network architect is choosing between eBGP and OSPF for the underlay of a new IP fabric. The fabric will have 100 leaf switches and 10 spine switches. The team values fast convergence, minimal configuration, and the ability to scale to a larger fabric in the future. Which underlay protocol choice is most appropriate, and why?

OSPF with a single area and all switches in the same area

OSPF with multiple areas to improve scalability

eBGP with a unique ASN for every switch in the fabric

eBGP with a private ASN per leaf and a single ASN for all spines

In a Virtual Chassis, how do member switches communicate with each other to synchronize state and forward traffic?

Through the Internet using IPsec tunnels

Through a dedicated out-of-band management network

Through a shared VLAN on the access layer

Through the Virtual Chassis control link and fabric links

What is the primary purpose of a Virtual Chassis in a Juniper data center network?

To provide a dedicated backup power source for network switches

To replace the need for routing protocols in a data center

To enable multiple switches to operate as a single logical device

To encrypt all traffic between switches in a data center

When adding a new member to an existing Virtual Chassis, what must be done first?

Connect the new switch to the Virtual Chassis using member links

Upgrade the new switch to the latest software version

Set the mastership priority to 255

Configure the new switch with a unique hostname
