A BIG-IP has a trunk (trunk1) with interfaces 1.1 and 1.2, and VLAN30 is tagged on trunk1. A frame with tag 30 arrives on interface 1.1. Which interfaces can this frame egress on?

Neither interface; the frame is dropped

An administrator notices that traffic from VLAN10 to a destination is not working. The route table shows a static route for the destination via 10.0.0.1, and the interface for VLAN10 is up. Which statistic or status would BEST confirm the issue is on the egress path?

The egress interface statistics show packets in but no packets out

The trunk statistics show no errors

The route status shows the route is 'up'

The interface statistics for VLAN10 show increasing packets out

A BIG-IP must forward a packet to 10.20.30.40. The routing table contains the following routes: 10.0.0.0/8, 10.20.0.0/16, and 10.20.30.0/24. Which route will be selected?

All routes are used in a round-robin fashion

A BIG-IP has a trunk (trunk1) with interfaces 1.1 and 1.2, and VLAN40 is tagged on trunk1. A frame with tag 40 arrives on interface 1.1. The administrator notices the frame is not being forwarded out interface 1.2. What is the MOST likely cause?

VLAN40 is not tagged on interface 1.2

Interface 1.1 is the only member of VLAN40

Part of the Explain the relationship between interfaces, trunks, VLANs, self-IPs, routes and their status/statistics domain, which makes up ~23% of our current practice bank. F5 does not publish an official question count, but from its 30-minute exam (~10–20 total, ~2–5 in this domain), expect 1–1 from this objective — we provide 19 practice questions to prepare you well beyond it.
