F5CAB1 Install, Initial Configuration, and Upgrade Practice Question
Which TWO of the following are mandatory requirements when setting up a BIG-IP license via the 'Base Registration Key' method?
⚠ Common exam trap
Candidates often believe that a license file can be manually uploaded without any internet access, failing to realize that the 'Base Registration Key' method specifically requires active outbound connectivity to F5 servers.
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
✓
The management interface must have outbound internet access.
The base registration key method requires the BIG-IP to reach the F5 licensing servers to exchange the key for a license file. This process necessitates both outbound internet access for the device and a valid registration key provided by F5. Without these, the device cannot validate its entitlement, and the licensing process will fail, leaving the system in an unlicensed state where traffic processing is effectively disabled.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The device must be part of an HA cluster.
Why it's wrong here
Licensing a BIG-IP is independent of HA configuration. A standalone unit can and often is licensed before being joined to a cluster. HA status is a secondary configuration step, and requiring it for licensing would prevent the initial setup of any standalone F5 appliance, which is a common deployment scenario.
- ✓
The management interface must have outbound internet access.
Why this is correct
The activation process involves an automated call-home to F5's activation servers to verify the key and generate the license. If the management interface lacks a route to the internet, this communication is blocked, and the system cannot complete the automated activation process, requiring manual offline activation instead.
- ✓
A valid base registration key must be provided.
Why this is correct
The base registration key is the unique identifier for the customer's entitlement. It is mandatory for the system to identify which features and throughput levels should be enabled. Without this key, the system has no reference to pull the correct license file, making it impossible to perform automated activation.
- ✗
The device must be running in FIPS-compliant mode.
Why it's wrong here
FIPS compliance is an optional security enhancement and is not a requirement for standard licensing. Most F5 deployments do not require FIPS mode, and enabling it adds significant configuration overhead. It has no bearing on the ability of the system to activate its license via the base registration key.
- ✗
The user must have a physical smart card.
Why it's wrong here
Smart cards are used for physical authentication in specific high-security environments, not for the standard licensing process. Licensing is based on the registration key and the device identity, which does not involve smart card authentication. Including this as a requirement is incorrect and irrelevant to standard F5 BIG-IP administration.
