CompTIA SK0-005 Exam - Topic 2 Question 74 Discussion

Actual exam question for CompTIA's SK0-005 exam

Question #: 74
Topic #: 2

A technician is configuring a server that will need to accommodate a planned network upgrade. All hosts will be changed from 10Gb copper to 25Gb fiber. Which of the following would best suit the requirements?

AFCoE

BVLAN ID

CSFP

DHBA

Show Suggested Answer

Suggested Answer: C

The upgrade involves transitioning from 10Gb copper to 25Gb fiber, which requires appropriate network interface hardware:

FCoE (A) - Fibre Channel over Ethernet: This protocol allows Fibre Channel to run over Ethernet networks, but it does not address the physical change from copper to fiber.

VLAN ID (B): VLANs segment networks but do not impact the physical connectivity (copper vs. fiber).

SFP (C) - Small Form-factor Pluggable: SFP transceivers are hot-swappable modules used in network interfaces to support fiber connections. A 25Gb SFP28 transceiver would be required for the transition from 10Gb copper to 25Gb fiber. This is the correct answer.

HBA (D) - Host Bus Adapter: HBAs are typically used for storage connectivity (such as Fibre Channel SANs), not general network upgrades.

Since SFP modules allow servers to support fiber connections, this is the best choice for upgrading from 10Gb copper to 25Gb fiber.

VLAN ID? I don’t see how that fits in this scenario.

FCoE is not necessary here, just stick with SFP.

Wait, are we sure HBA is the right choice?

25Gb fiber needs SFP modules.

HBA sounds familiar, but I'm uncertain if it's the right choice for just upgrading the speed. I need to think this through.

I practiced a question similar to this, and I think SFP modules are crucial for the fiber connections, but I can't recall the specifics.

I think VLAN ID is more about network segmentation, so it might not be relevant here.

I remember studying about FCoE, but I'm not sure if it's the best fit for just upgrading to 25Gb fiber.

I'm a bit confused by this question. I know we're talking about a network upgrade, but I'm not sure I fully understand the differences between all the options. I'll have to review my networking notes and try to reason through this step-by-step.

Okay, I've got this. The key is that the question is asking about the best solution for a 25Gb fiber network upgrade. So the answer has to be something related to fiber optic connectivity, not just general networking terms. I'm pretty confident SFP is the right choice here.

Hmm, I'm not totally sure about this one. I know the question is asking about the best solution for the network upgrade, but I'm not familiar with all the networking terms like FCoE and HBA. I'll have to think this through carefully.

This looks like a straightforward networking question. I think the answer is SFP, since that's the type of fiber optic transceiver that would be needed for the 25Gb fiber upgrade.
