Question 1

What is the key difference between static routing and dynamic routing?

Accepted Answer

Static routes are manually configured; dynamic routes are learned automatically via routing protocols

Answer

Static routes are manually entered by an administrator and do not adapt to topology changes, while dynamic routing protocols automatically discover and update routes based on network changes.

Question 2

Which dynamic routing protocol is commonly used within an enterprise campus network and is classified as a link-state protocol?

Accepted Answer

OSPF

Answer

OSPF (Open Shortest Path First) is a link-state routing protocol widely used within enterprise networks, building a complete topology map and computing shortest paths using Dijkstra's algorithm.

Question 3

What does the subnet mask /24 indicate about an IP network?

Accepted Answer

The first 24 bits are the network portion, leaving 8 bits for hosts (254 usable hosts)

Answer

A /24 prefix length means the first 24 bits identify the network, leaving 8 bits for host addresses, yielding 256 addresses with 254 usable host addresses.

Question 4

What is the purpose of DHCP in an IP network?

Accepted Answer

To automatically assign IP addresses and network parameters to client devices

Answer

DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses, subnet masks, default gateways, and DNS server addresses to client devices on a network.

Question 5

Which DHCP message does a client send to discover available DHCP servers on the network?

Accepted Answer

DHCP Discover

Answer

A DHCP Discover message is broadcast by a client to locate available DHCP servers; it is the first step in the DORA (Discover, Offer, Request, Acknowledge) process.
