Actual exam question for Cisco's 300-610 exam
Question #: 79
Topic #: 5
[All 300-610 Questions]

An engineer must design the compute portion of a data center environment. The environment includes:

* direct-attach Fibre Channel storage array with four 32 G Fibre Channel ports per controller

* Cisco UCS B-series servers equipped with Cisco UCS IOM 2408 Fabric Extenders

* Cisco 6454 Fabric Interconnects

The fabric interconnects conned to the LAN via 100G ports, the SAN via 32 G Fibre Channel ports, and the IOM 2408 via 10 G ports. Which storage connectivity strategy must the engineer choose?

Show Suggested Answer Hide Answer
Suggested Answer: D

When restrictions on oversubscription ratios are disabled, the bandwidth allocation among the shared ports is proportionate to the configured speed. (If the configured speed is auto, then bandwidth is allocated assuming a speed of 4 Gbps.) For example, if you have three shared ports configured at 1, 2, and 4 Gbps, then the allocated bandwidth ratio is 1:2:4. In Cisco SAN-OS Release 3.0 and later (or when restrictions on oversubscription ratios are enabled), port bandwidths are allocated in equal proportions, regardless of port speed, so, the bandwidth allocation for the same three ports mentioned in the example would be 1:1:1.

I’m a bit confused about the Fibre Channel links. I thought we needed more than two links for redundancy, but I can't recall the exact numbers.

I think I practiced a similar question where we had to choose between different PortChannel configurations. I feel like option B might be the right choice here.

I think option C looks right to me. The function signature mentions a 'url' and a 'payload' parameter, so passing the IP address as the last argument seems logical.

I'm just hoping the exam doesn't ask me to calculate the total port count or something. That would be like asking a chef to solve differential equations.

Option D seems a bit odd with the 'back-to-back' PortChannel. I'm not sure I've seen that configuration before, but it could be an interesting way to approach the problem.
