A streaming service runs its video delivery platform in an active-active configuration across two cloud regions. During a regional outage, all traffic shifts to the remaining region, but users experience buffering. The remaining region was sized for 50% of peak traffic. What is the most likely cause of the buffering?

The remaining region lacks sufficient capacity to handle 100% of peak traffic

The active-active configuration is not supported for video streaming

The remaining region is not receiving replicated data

The DNS failover is not working correctly

Which fault tolerance mechanism is designed to prevent a single point of failure in network connectivity?

Uninterruptible power supply (UPS)

What is the primary purpose of Quality of Service (QoS) in a network?

To prioritize critical traffic to ensure performance

To block unauthorized access to the network

To increase the total bandwidth of the network

What is the primary purpose of an active-passive processing site configuration?

To allow both sites to process different types of workloads independently

To provide a standby site that can take over if the primary site fails

To reduce the cost of hardware by using only one site

To distribute traffic evenly across multiple sites for performance

A VoIP phone system and a nightly backup job share a WAN link. During backups, call quality degrades. The network administrator wants to ensure voice traffic is never delayed by the backup traffic. Which QoS approach is most appropriate?

Increase the WAN link bandwidth

Apply a priority queue to VoIP traffic and a lower-priority queue to backup traffic

Use round-robin scheduling for all traffic
