After the upload is complete, what will the system dobeforethe image appears in the GUI under:
System Software Management Image List?

Suggested Answer: B Vote an answer

When a TMOS ISO file is transferred to/shared/images/, the BIG-IP automatically performs a validation step:
Checksum Verification
* Before the image becomes visible in the GUI, the systemverifies the internal checksumembedded inside the ISO.
* This ensures:
* The file was fully transferred
* The image is not corrupted
* It matches the official F5 release signature
* Only after passing this verification does the GUI display the ISO under "Available Images." Why the other options are incorrect:
A). Reboot into a new partition
* No reboot occurs simply from uploading an image.
C). Copying into /var/local/images/
* This directory isnotused for ISO storage.
* All valid images remain in/shared/images/.
Thus, the correct system action ischecksum verification.
