[All 350-801 Questions]

Which two technical reasons make QoS a necessity in a video deployment? (Choose Two)

Show Suggested Answer Hide Answer
Suggested Answer: D

The Cisco Unified Communications Manager (CUCM) uses SIP Phone OAuth Port (5090) to listen for SIP line registration from Jabber OnPremise devices over TLS. However, CUCM uses SIP Mobile Remote Access Port (default 5091) to listen for SIP line registrations from Jabber over Expressway through mTLS. Both of these ports are configurable.

I'm just impressed they used the word 'bursty' in a networking question. That's some advanced vocabulary right there.

This is a no-brainer. Anyone who's tried to watch a video on a bad connection knows that QoS is the difference between smooth streaming and a pixelated mess.

I agree with Luann and Brandon. But I also think C is relevant - the variable bitrate of the video stream means QoS is needed to handle those fluctuations.

Low response time is also super important for video, so A should definitely be one of the answers.

B and D seem like the obvious choices here. QoS is crucial for managing variable video traffic and ensuring enough bandwidth is provisioned.
