Objective 2.2

N10-009

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.

2-2Network Implementation

Packets destined for stations that do not belong to a given VLAN must be forwarded through which device?

A hub connected directly to the switch's native VLAN segmentA hub simply repeats signals at Layer 1 and cannot forward traffic between logically separate VLANs.
A router, or a device that supports fallback bridging between VLANsCorrect · your answerCorrect: routing (or fallback bridging) is explicitly named as the mechanism for inter-VLAN forwarding.
A wireless access point operating in autonomous access point modeAn autonomous AP handles wireless clients but does not route traffic between separate VLANs.
A firewall configured to perform network address translation (NAT)NAT translates addresses between public and private space; it plays no role in forwarding traffic between VLANs.
A managed switch with 802.1Q trunking enabled on all its ports802.1Q trunking carries multiple VLANs over one link but does not itself route traffic between them.

Correct.

Checked against cisco.com, July 2026

Concept

A VLAN is a logically segmented, separate broadcast domain, so traffic cannot cross VLAN boundaries at Layer 2 alone.

Why B

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.

Source

Each VLAN is considered a logical network, and packets destined for stations that do not belong to the VLAN must be forwarded through a router or a device supporting fallback bridging.

Now you: objective 2.2 questions

No account needed. The explanation opens when you answer.

Sample question 1 of 3

2-2Network Implementation

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

2-2Network Implementation

Which IEEE standard does the rapid per-VLAN spanning-tree plus (rapid-PVST+) protocol base its algorithm on?

Sample question 3 of 3

2-2Network Implementation

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?
