2.2 Given a scenario, configure switching technologies and features.
Objective 2.2 sits in Network Implementation, which carries 20% of the Network+ exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
Per Cisco's VLAN configuration guide, packets destined for stations that do not belong to a given VLAN must be forwarded through which device?
The concept
A VLAN is a logically segmented, separate broadcast domain, so traffic cannot cross VLAN boundaries at Layer 2 alone.
Why this answer
The source states packets destined for stations outside the VLAN must be forwarded through a router or a device supporting fallback bridging, since VLANs are separate logical networks.
- Correct: routing (or fallback bridging) is explicitly named as the mechanism for inter-VLAN forwarding.
- BNAT translates addresses between public and private space; it plays no role in forwarding traffic between VLANs.
- CAn autonomous AP handles wireless clients but does not route traffic between separate VLANs.
- DA hub simply repeats signals at Layer 1 and cannot forward traffic between logically separate VLANs.
- E802.1Q trunking carries multiple VLANs over one link but does not itself route traffic between them.
Now you: objective 2.2 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
A network mixes older switches that lack extended system ID support with a newer Catalyst 9300 switch that supports it. The administrator lowers the newer switch's priority, but an older switch still becomes root. Why?
Sample question 2 of 3
Which IEEE standard does the rapid per-VLAN spanning-tree plus (rapid-PVST+) protocol base its algorithm on?
Sample question 3 of 3
An administrator overrides the MAC address of one SVI on a Catalyst 9300 switch using the mac-address command, because that SVI requires Layer 3 injected packets. What must be true of all other SVIs and routed ports on the device?
