Protocol Optimization

Correct Answer: Implement QoS and prioritize VoIP traffic

Implementing Quality of Service (QoS) and prioritizing the VoIP traffic is the best solution to optimize the network for VoIP performance during times of heavy internet use. QoS can be used to give higher priority to VoIP traffic, which is sensitive to delay and packet loss. This ensures that VoIP traffic is treated with higher priority than other traffic, leading to improved call quality. The remaining options are not as effective: Increasing the bandwidth of the internet connection might temporarily alleviate the problem, but doesn't necessarily prioritize VoIP traffic. Configuring VoIP to use alternative codecs might reduce the bandwidth used by VoIP, but doesn't necessarily improve the call quality during times of heavy internet use. Enabling Network Address Translation (NAT) can help with the routing of IP packets on the network, but doesn't directly influence the quality of VoIP calls.

Correct Answer: Quality of Service (QoS)

Quality of Service (QoS) is the best answer. It is a protocol optimization technique that helps manage the data traffic on a network to reduce latency and packet loss. It gives priority to important data over less crucial data during times of high demand or peak hours. This is why it could help in reducing the problem of network experiencing intermittent delays during peak hours. In contrast, Port bonding increases the bandwidth and provides redundancy but doesn't manage the traffic, Network segmentation divides a network into smaller parts to improve performance and security but it doesn't optimize the traffic, and Network Address Translation (NAT) translates IP addresses of a private network to a public address. It mainly aids in alleviating the scarcity of IPv4 addresses and it doesn't help in managing the network traffic as needed in this case.

Correct Answer: Quality of Service (QoS)

Quality of Service (QoS) is the correct answer because it prioritizes certain types of traffic on a network and guarantees a certain level of performance, which is needed for a video conferencing application that requires low latency and guaranteed bandwidth. The other options are not correct for this scenario. FTP acceleration does not guarantee bandwidth or prioritize traffic, it only improves the speed of file transfers. Dynamic routing merely determines the best path for data packets, it does not prioritize traffic or guarantee bandwidth. Port bonding is a technique used to increase the bandwidth available to a server by teaming multiple network ports, but it doesn’t provide any sort of traffic prioritization or guarantee bandwidth.
