JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2024) — Question 29

You are adding a new EX4300 member switch to your existing EX4300 Virtual Chassis. However, the new member is not running the same Junos version as the other members.
By default, what is the expected behavior in this scenario?

Answer options

• A. the Virtual Chassis will transition into a split brain situation between the existing master Routing Engine and the switch running the different version.
• B. The new switch will automatically pull the correct version from the master Routing Engine and perform the necessary upgrade.
• C. The new switch will be assigned a member ID and then placed in an inactive state.
• D. The new switch is not recognized by the Virtual Chassis.

Correct answer: C

Explanation

The correct answer is C because when a new switch with a different Junos version is added, it cannot participate in the Virtual Chassis until it runs the same version, resulting in it being inactive. Option A is incorrect as there won't be a split brain scenario; option B is false because the new switch does not automatically upgrade; and option D is incorrect because the switch is acknowledged but placed in an inactive state.
