F5CAB1 Install, Initial Configuration, and Upgrade Practice Question
An administrator is performing an initial setup on a new BIG-IP appliance via the serial console. After completing the basic network and management IP configuration, the administrator needs to verify that the management route is correctly established. Which command should the administrator execute from the TMOS shell?
⚠ Common exam trap
Candidates often confuse management routes with general routing tables. They frequently select 'show net route' instead of 'show sys management-route', failing to distinguish between data plane and management plane traffic.
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
✓
show /sys management-route
The TMOS shell (tmsh) provides administrative control over the BIG-IP system. Executing the show /sys management-route command displays the active management routes configured on the management interface, ensuring out-of-band administrative traffic routes correctly through the designated gateway, which is a critical validation step during initial deployment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
show /sys management-route
Why this is correct
This command specifically queries the management routing table within tmsh, displaying the configured gateway and destination subnets for the management interface. Verifying this confirms that out-of-band administrative access functions properly before disconnecting the serial console.
- ✗
show /net route
Why it's wrong here
show /net route is not a valid TMOS shell command; routes are inspected with list /net route, so the administrator gets an error rather than the management route. It is tempting because show is used in tmsh for some objects, but route verification requires the list verb.
- ✗
list /sys global-settings
Why it's wrong here
list /sys global-settings displays global configuration variables, not the routing table, so the management route cannot be confirmed. It is tempting because list commands are the standard way to inspect TMOS configuration objects, and this one is correct when auditing global settings rather than routes.
- ✗
show /sys ip-address
Why it's wrong here
The `show /sys ip-address` command lists interface IP addresses, not the management route table, so it cannot confirm gateway reachability. It is tempting because it verifies management IP configuration, which is the preceding setup task; it would be the right choice when confirming the management address rather than the route.
