F5 Networks F5CAB1 Exam - Topic 4 Question 1 Discussion

Actual exam question for F5 Networks's F5CAB1 exam
Question #: 1
Topic #: 4
[All F5CAB1 Questions]

The BIG-IP Administrator uses Secure Copy Protocol (SCP) to upload a TMOS image to the /shared/images/ directory in preparation for a TMOS upgrade.

After the upload is completed, what will the system do before the image is shown in the GUI under:

System Software Management Image List?

Show Suggested Answer Hide Answer
Suggested Answer: B

When a TMOS image (.iso file) is uploaded into the /shared/images/ directory, the BIG-IP performs an internal validation step before the ISO appears in the GUI.

1. The system verifies the internal checksum

BIG-IP automatically reads the embedded checksum inside the ISO file

Verifies integrity of the uploaded image

Confirms the file is not corrupted or incomplete

Ensures the image is a valid F5 TMOS software image

Only after this checksum verification succeeds does the image appear under:

System Software Management Image List

Why the other options are incorrect:

A . The system performs a reboot into a new partition

Uploading an ISO file never triggers a reboot.

C . The system copies the image to /var/local/images/

All valid TMOS images remain in /shared/images/.

No copying occurs.

Definitely B. Without verification, the upgrade could fail.

B) The system verifies the internal checksum. Can't have any corrupted images, that would be a disaster!

B) The system verifies the internal checksum. That's the logical step before the image is ready for use.

I could be wrong, but I thought the system needed to check the image's integrity before anything else. That sounds like option B to me.

I remember discussing the reboot process, but I don't think that happens right away. It seems like the verification step is crucial first.

I'm not entirely sure, but I feel like the image might get copied to /var/local/images/ first. I think I saw a similar question about file paths in our practice exams.
