How does a switch learn which MAC address is associated with each of its ports?

It sends ARP requests to all connected devices

It is configured manually by the network administrator

It broadcasts all frames until the destination responds

It examines the source MAC address of incoming frames and records it in its MAC address table

How do port numbers enable multiple applications to share a single IP address?

By assigning each application a unique port number to direct traffic to the correct process

By using different MAC addresses for each application

By creating separate virtual IP addresses for each application

By using different network protocols for each application

A small office has a single flat network with all devices connected to one switch. The office is growing and will add a second floor with its own switch. The two switches will be connected, and the network will use the 192.168.1.0/24 subnet. What is the primary function of the router that will be added to connect this network to the internet?

Forward packets between the local subnet and the internet based on IP addresses

Forward frames between the two switches based on MAC addresses

Provide wireless access for mobile devices

Assign IP addresses to all devices on the network

A network administrator is setting up a new branch office with 50 workstations. The administrator wants to minimize manual configuration and ensure that each workstation receives an IP address, subnet mask, default gateway, and DNS server automatically. Which service should be deployed?

Static IP assignment via group policy

What is the primary purpose of the Address Resolution Protocol (ARP)?

To resolve an IP address to a MAC address on a local network

To route packets between different networks

To assign IP addresses to hosts dynamically

To resolve a MAC address to an IP address

Part of the Network and Systems Security domain, which makes up ~28% of our current practice bank. GIAC (SANS) does not publish an official question count, but from its 120-minute exam (~50–80 total, ~14–22 in this domain), expect 5–7 from this objective — we provide 53 practice questions to prepare you well beyond it.
