What is the primary role of a Layer 3 device, such as a router, in a network?

To filter traffic based on application-layer protocols

To forward frames within the same broadcast domain based on MAC addresses

To forward packets between different IP networks based on Layer 3 addressing

To translate private IP addresses to public IP addresses for internet access

When a router receives a packet destined for 192.168.10.5, what does it use to determine the next hop?

The MAC address table, which maps MAC addresses to ports

The routing table, which maps destination networks to next-hop addresses

The DNS cache, which maps hostnames to IP addresses

The ARP cache, which maps IP addresses to MAC addresses

A network administrator is troubleshooting a routing loop. The administrator captures packets on a router and notices that the TTL field in the IP header is decremented each time the packet passes through a router. What happens when the TTL reaches zero?

The packet is sent to the default gateway

The packet is forwarded to the next hop with a TTL of 0

The packet is discarded and an ICMP Time Exceeded message is sent to the source

The packet is fragmented and forwarded

What is the purpose of the longest prefix match rule in routing?

To select the route with the highest administrative distance

To select the most specific route that matches the destination

To select the route that was added most recently

To select the route with the lowest metric
