CompTIA Exam N10-008 Topic 3 Question 65 Discussion

Actual exam question for CompTIA's N10-008 exam
Question #: 65
Topic #: 3
[All N10-008 Questions]

A! which of the following layers of the OSI model can switches operate? (Select two).

Show Suggested Answer Hide Answer
Suggested Answer: B, C

Switches operate atLayer 2andLayer 3of the OSI model. Here's a brief explanation for each layer:

Layer 2 (Data Link Layer):

Switches primarily operate at this layer.

They use MAC addresses to forward frames within a local network (LAN).

Switches create and maintain MAC address tables to make forwarding decisions.

Examples of switches include Ethernet switches and VLAN switches.

Layer 3 (Network Layer):

Some advanced switches (known asLayer 3 switches) can perform routing functions.

Layer 3 switches can route traffic between different subnets within the same LAN.

They use IP addresses to make routing decisions.

Layer 3 switches combine the features of switches and routers.

Haha, I bet the answer is B and C. Switches are all about that Ethernet and IP magic, am I right or am I right?

Hmm, I think the answer is B and D. Switches can operate at Layer 2 and Layer 4, no? This exam is a real head-scratcher!

I'd go with B and C. Switches can definitely handle Layer 2 and Layer 3 traffic, right?

Layers 1 and 2, of course! Switches are all about that physical and data link action.

Hmm, I'm going to go with Layer 2 and Layer 3. Switches need to operate at both the data link and network layers to do their job properly. Anything else is just witchcraft.

The correct answers are Layer 1 and Layer 2. Switches don't operate at the higher layers like transport (Layer 4) or session (Layer 5). That's just crazy talk!

I think Layer 2 and Layer 3 are the correct answers. Switches can operate at the data link layer (Layer 2) and the network layer (Layer 3) to route packets based on IP addresses.

Layer 1 and Layer 2 are the correct answers. Switches operate at the data link layer (Layer 2) to forward frames based on MAC addresses, and they can also operate at the physical layer (Layer 1) to provide electrical, mechanical, and functional connectivity.
