JNCIP-DC: Juniper Networks Certified Professional – Data Center (2022) — Question 31

You are asked to enable plug-and-play for future line card switches in an active VCF without making any future Junos configuration changes. You are also required to ensure that all new line cards are automatically upgraded to the correct Junos version without any manual intervention.
In this scenario, which two actions will accomplish this task? (Choose two.)

Answer options

• A. Ensure that the newly inserted line card's MAC addresses are present in the DHCP configuration for ZTP.
• B. Configure the auto-sw-update parameter on the VCF before inserting new line cards.
• C. Set the Virtual Chassis as pre-provisioned before the line cards are inserted.
• D. Set the Virtual Chassis as auto-provisioned before the line cards are inserted.

Correct answer: B, D

Explanation

The correct actions to enable automatic updates and plug-and-play functionality are to configure the auto-sw-update parameter on the VCF (option B) and to set the Virtual Chassis as auto-provisioned (option D). Options A and C do not directly address the requirements for automatic upgrades and plug-and-play functionality.
