Discuss GIAC GSNA Exam Topic 6 Question 29

Choose the benefits of deploying switches over hubs in your infrastructure.

Each correct answer represents a complete solution. Choose two.

ALayer 2 switches allow for the creation of Virtual LANs providing options for further
segmentation and security.

BSwitches lower the number of collisions in the environment.

CSwitches create an environment best suited for half duplex communications. This improves
network performance and the amount of available bandwidth.

DLayer 2 switches increase the number of broadcast domains in the environment.

Suggested Answer: A, B

Switches differ from hubs in that they break up Collision Domains. Each port on a switch equals one Collision Domain. Therefore, a switch will

lower the number of collisions within the infrastructure.

Managed switches typically offer the ability to create Virtual LANs. Virtual LANs allow the switch to create multiple LANs/network segments

that are Virtual. This allows the switch to create additional environments where needed.

Lowering collisions is key for better performance, no doubt!

Half duplex? Nah, I thought switches were all about full duplex.

Wait, do switches really create more broadcast domains? That sounds off.

Madonna 12 months ago

I agree, VLANs are super useful for security and segmentation.

Shawnda 12 months ago

Switches definitely reduce collisions, that's a big plus!

I recall that switches actually create more collision domains, not broadcast domains. So, I think option D is definitely wrong.

I practiced a question similar to this, and I think switches do improve performance, but I'm confused about the half duplex part in option C.

Evette 1 year ago

I'm not entirely sure, but I feel like VLANs are a big deal with switches. So, option A might be correct too.

Eleonora 1 year ago

I remember that switches reduce collisions, which definitely helps with network efficiency. I think option B is one of the answers.

This seems like a straightforward question about the incident response process. I'll need to carefully review the stages to determine when a full system backup would be most appropriate.

I remember the default gateway is related to how devices communicate outside their local network, but I'm not sure which option directly describes it.

I remember we discussed how rubber stamp signatures need strict controls because of the risk of misuse. Maybe A is the right choice?
