Actual exam question from Cisco's 350-801

Question #: 30
Topic #: 1

A company deploys centralized Cisco UCM architecture for a hub location and two remote sites.
✑ The company has only one ITSP connection at the hub location, and ITSP supports only G.711 calls.
✑ Remote site A has a 1-Gbps fiber connection to the hub location and calls to and from remote site A use G.711 codec.
✑ Remote site B has a 1-T1 connection to the hub location and calls to and from remote site B use G.729 codec.
Based on the provided guidance, a Cisco voice engineer must design media resource management for the customer. What is the method that needs to be followed?

A. configure the hardware transcoder on the site B router
B. configure the hardware transcoder on the site A router
C. configure the hardware transcoder on the hub location router
D. configure the software transcoder on Cisco UCM to support voice calls to and from both remote sites

I think it should be C, so you can maintain G729 calls across the T1.

Correct answer is C. Site B has a T1 connection and we don't want to force them to limit the number of calls. As an administrator, i would take the incoming calls from site B in G729 and do a transcode at the hub location, and receive an Incoming call to Site B in G 711 and transcode it to G729 and traverse over T1. Win Win situation.

Per SRND, planning media resources is conference remotely and transcode centrally therefor answer should be C

Selected Answer: C

Should be at the Hub site so that it can go thru the T1 using G729 and get transcoding at the Hub.

Site A not connected to Site B directly, and connected through Hub, so if we put the Hardware Transcoder in Hub, that also can be used for Site A talks to Site B through Hub with Hardware Transcoder. Site B got limited bandwidth and that is why using G.729, so definitely the Hardware Transcoder should be in site Hub, so both Site A and Hub can use that Hardware Transcoder for communicate to site B. The correct answer is C.

If you you are using G729 for remote location B, you are doing so to conserve bandwidth at the T1 link between Location B and the Hub Location. Converting from G729 to G711 at remote location B will force the traffic back to the hub location to be G711, which means that the G729 benefit (reduce bandwidth consumption) will not be used at all. This answer must be C (transcoder at the hub location).

I will go with C because it is centralized setup . Local transcoders are advised with multi site deployments right ?

I go or C, because the ITSP connection is not the connection connecting Site B and Hub, its a different one, therefor I would install trancoder @ hub location to maximize calls over T1 connecion.

Definitely think it is B because the ISP can only support G711. Site B must transcode G729 into G711 before leaving the site.

I agree with @Collabhunter and @Landrey First, we can not assume that Site A and Hub have transcoders. which means that they will need transcoders to communicate to Site B. Scenario 1: if we place transcoders in site A --> Hub can't communicate to Site B Scenario 2: if we place transcoders in Hub --> Site A can't communicate to site B That's why we need to place transcoders in Site B, so both sites (hub and site A) can communicate to site B

In real world I would say to put transconding on each site, due WAN bandwidth / consumption, this will be more feasible.. But since this is a Cisco Exam and we have one option to go... Im going with Landrey said, xcode needs to be place on site B, so both Hub and Site A (g711) could call site B

The correct answer is C. You place the hardware (not software transcoder - there is no such thing) at the hub location. The trancoding resource takes the incoming G.711 media stream from the ISP (loacted at the hub location) and transcodes to a G.729 media stream that is routed to an endpoint located at site B thus conserving WAN bandwidth. There is no need to conserve WAN bandwith between the hub location and Site A therefore no need to transcode to G.729. If you were to place the trancoding resource at SiteB you would be sending a G.711 call across the T1 link (low bandwidth issues etc) only to be trancoded at site B - thats not something you do in the real world.

I think the hardware transcoder should be on the Site B, because all their calls no matter the destination will be using G729 against G711 so the transcoder source must be placed locally
