A network manager is troubleshooting intermittent application slowdowns. Monitoring shows that the router's CPU is at 90% during peak hours, but interface utilization is only 40%. The manager suspects that the router is processing too many broadcasts. Which change would most directly reduce the router's CPU load?

Segment the network into smaller broadcast domains using VLANs and subnets.

Disable the router's firewall features to free up CPU cycles.

Increase the router's memory to handle more routing table entries.

Replace the router with a higher-end model that has more CPU cores.

What is the purpose of authentication in network security?

To encrypt data transmitted over the network

To verify the identity of a user or device

To monitor network traffic for anomalies

To control what resources a user can access

Which of the following best describes a 'node' in a network?

Any device that can send, receive, or forward data on the network

The central device in a star topology

The software that manages network traffic

The physical cable that connects devices
