F5CAB1 Install, Initial Configuration, and Upgrade Practice Question
Which license activation method is required for a BIG-IP device that is physically isolated from the Internet?
⚠ Common exam trap
Candidates often guess that there is a 'no-license' mode or that they can use a proxy. The only official method for air-gapped devices is the manual dossier-based workflow.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Manual activation via dossier file upload.
Devices without Internet access must use the manual license activation process. This involves generating a dossier on the F5 device, submitting it to the F5 licensing server via a machine with Internet access, receiving a license file, and uploading it back to the BIG-IP. This process ensures that highly secure environments can license their F5 hardware without violating air-gap security policies.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Automatic activation via F5 Licensing Server.
Why it's wrong here
Automatic activation requires an outbound connection from the BIG-IP device to the F5 licensing servers. In an isolated, air-gapped environment, the device cannot reach the Internet, making this method impossible to complete. The connection attempt would time out, resulting in an activation failure during the setup.
- ✓
Manual activation via dossier file upload.
Why this is correct
Manual activation is specifically designed for isolated environments. By generating a dossier, the administrator obtains the necessary hardware-specific information to request a license key from the F5 portal. The resulting response file is then uploaded to the BIG-IP, completing the licensing process without an active Internet connection.
- ✗
Activation via the F5 BIG-IQ platform.
Why it's wrong here
While BIG-IQ can manage licenses, it also requires connectivity to the F5 servers to fetch them. If the entire network environment is isolated, the BIG-IQ itself would not have the necessary internet access to perform the activation. This does not address the fundamental need for manual licensing.
- ✗
Activation using the local 'lic-key' command.
Why it's wrong here
There is no 'lic-key' command that performs local activation without an external source. All licensing relies on cryptographically signed files generated by F5 servers. Even if a local command existed, it could not generate a valid, signed license key locally without interacting with F5's secure infrastructure.
