JNCIP-DC: Juniper Networks Certified Professional – Data Center (2023) — Question 35

You are deploying your data center switches using ZTP.
A brand new QFX5120 switch has been booted for the first time. It is failing to upgrade to the desired Junos OS version.
In this scenario, which two actions would you take to troubleshoot this problem? (Choose two.)

Answer options

• A. Ensure that the correct Juniper default FTP password is defined under the DHCP configuration option and restart the FTP service.
• B. Log in to the switch through the console and look for log messages that might indicate the cause of the issue.
• C. Ensure that anonymous login is enabled on the FTP server and that the FTP service is running.
• D. From the configuration mode, issue the load factory-default and commit commands to re-initiate the ZTP request.

Correct answer: A, B

Explanation

The correct actions are A and B. Option A ensures that the switch can authenticate with the FTP service to download the necessary files, while option B allows for checking logs that may provide insight into why the upgrade is failing. Options C and D are not directly addressing the authentication issue or diagnosing the problem effectively.
