IP Addressing and Networking Quiz

Which of the following is the correct range of IP addresses for a Class A network?

• 0.0.0.0 to 127.255.255.255

• 128.0.0.0 to 191.255.255.255

• 192.0.0.0 to 223.255.255.255

• 224.0.0.0 to 255.255.255.255

What is the default subnet mask for a Class B IP address?

• 255.0.0.0

• 255.255.0.0

• 255.255.255.0

• 255.255.255.255

Which of the following IP address classes is used for multicast addressing?

• Class A

• Class B

• Class D

• Class E

What is the range of IP addresses for a Class C network?

• 192.0.0.0 to 223.255.255.255

• 128.0.0.0 to 191.255.255.255

• 0.0.0.0 to 127.255.255.255

• 224.0.0.0 to 239.255.255.255

In Classless Inter-Domain Routing (CIDR), what does the notation "192.168.10.0/24" represent?

• A network address with 24 bits for the network part

• A network address with 24 bits for the host part

• A Class A network with a 24-bit subnet mask

• A Class C network with a 24-bit subnet mask

What is the benefit of using CIDR over traditional classful addressing?

• More efficient use of IP address space

• Easier to manage IP address allocation

• Reduced routing table size

• All of the above

What is the primary purpose of Network Address Translation (NAT)?

• To provide security by hiding internal IP addresses

• To convert IPv6 addresses to IPv4

• To assign dynamic IP addresses to hosts

• To route packets across different networks

Which type of NAT involves translating multiple private IP addresses to a single public IP address?

• Static NAT

• Dynamic NAT

• Port Address Translation (PAT)

• Reverse NAT

Which of the following is NOT a typical use case for NAT?

• To allow multiple internal devices to access the internet using one public IP

• To map internal IPs to their corresponding external IPs

• To ensure packets are routed based on destination IP address

• To manage the address space more efficiently between networks

Which of the following defines how an IP packet is forwarded from one router to the next?

• Routing Protocol

• Address Resolution Protocol (ARP)

• Network Address Translation

• Layer 4 Port forwarding
