Actual exam question for Cisco's 350-801 exam

Question #: 46
Topic #: 10

[All 350-801 Questions]

An engineer implements a new Cisco UCM based telephony system per these requirements.

* The local Ethernet bandwidth is sized based on the total bandwidth per call

* A G 736 codec is used.

* The bit rate is 64 kbps

* The codec sample interval is 10 ms

* The voice payload size is 160 bytes per 20 ms

What should the size of the Ethernet bandwidth be per call?

A31.2 kbps

B38.4 kbps

C55.2 kbps

D87.2 kbps

Wait, how can it be that high? Seems off to me.

G.736 codec usually means lower bandwidth, but not that low!

55.2 kbps sounds right based on the payload size.

I think it’s definitely option D, 87.2 kbps.

The bit rate is 64 kbps, so it should be higher than that.

Hmm, I'm a bit confused on how to calculate the Ethernet bandwidth. I know we need to consider the codec, bit rate, and payload size, but I'm not sure how to factor in the Ethernet overhead. I'll have to review my notes and try to work through this step-by-step.

Alright, let me give this a shot. The bit rate is 64 kbps, and the voice payload is 160 bytes per 20 ms. We need to account for the Ethernet frame overhead, which includes the Ethernet header, IP header, UDP header, and RTP header. I think the total Ethernet bandwidth per call will be around 87.2 kbps.

I'm not sure, the question mentions Ethernet bandwidth, so we might need to factor in additional overhead. I'll have to think this through carefully.

This seems straightforward. The bit rate is 64 kbps, so the bandwidth per call should be 64 kbps, right?

Okay, let's think this through step-by-step. We have a G.726 codec with a bit rate of 64 kbps and a sample interval of 10 ms. The voice payload size is 160 bytes per 20 ms. I think we need to calculate the total bandwidth required per call, including overhead.

I think the Ethernet bandwidth should include some additional overhead for signaling, so maybe it's closer to 87.2 kbps? That sounds familiar.

If the bit rate is 64 kbps, I feel like the answer should be higher than 31.2 kbps, but I’m not confident about the exact calculation.

I think we practiced a similar question where we had to account for overhead, but I can't recall the exact formula we used.

I remember something about calculating bandwidth based on the codec and payload size, but I'm not sure how to apply it here.

This one seems pretty straightforward. I'll start by eliminating the options that are clearly control documentation techniques, like flowcharting and control questionnaires.

I remember we talked about the different methods for creating buckets in OSS, but I'm not sure if the ECS filesystem directory operation was discussed as a valid method.

I need to double-check my notes, but I think any direct LSP connectivity option could lead to issues as the number of sites grows.

This seems like a tricky one. There are a lot of details to consider with the different options. I think the key will be to really understand the scope of where this property applies - is it just for the REST API, the whole repository, Webdav, or Alfresco Share? I'll need to carefully read through each option and think about how they differ.

This reminds me of practice questions where they stressed consistency and comparability as primary needs. Maybe that's a clue for this one?

Candidate 4: Rough check suggests about 119 million; option A tends to be the right pick in these sets.
