Two types of IP addresses are ?

• IPv4

• Classless IPs

• Classful IPs

• IPv6

Which of the following accurately describes the bit size of IPv4 and IPv6 addresses?

• IPv4 addresses are 32 bits long, while IPv6 addresses are 64 bits long.

• IPv4 addresses are 64 bits long, while IPv6 addresses are 128 bits long.

• IPv4 addresses are 32 bits long, while IPv6 addresses are 128 bits long.

• IPv4 addresses are 128 bits long, while IPv6 addresses are 32 bits long.

Which of the following statements best describes classful addressing?

• Classful addressing allows for variable length subnet masking (VLSM).

• Classful addressing divides IP addresses into fixed-length network and host portions based on address classes.

• Classful addressing is commonly used in modern networking due to its flexibility and scalability.

• Classful addressing assigns IP addresses dynamically using protocols like DHCP.

What is a characteristic of classless addressing?

• Classless addressing uses fixed-length network and host portions based on predefined address classes.

• Classless addressing allows for efficient use of IP address space by allowing subnetting and supernetting.

• Classless addressing is limited to only IPv4 networks and cannot be implemented in IPv6 networks.

• Classless addressing is more rigid and less adaptable than classful addressing.

Which of the following IP address classes is reserved for multicast addresses?

• Class B

• Class C

• Class D

• Class E

Which of the following best describes CIDR (Classless Inter-Domain Routing)?

• CIDR is a subnetting technique that allows for the division of IP addresses into fixed-length network and host portions.

• CIDR is a protocol used for dynamically assigning IP addresses to devices on a network.

• CIDR is a method of allocating IP addresses based on predefined classes, such as Class A, Class B, and Class C.

• CIDR is a hierarchical addressing scheme that simplifies routing by aggregating IP prefixes into larger blocks.

What is the subnet mask needed to create 8 subnets from a Class C network address of 192.168.10.0?

• 255.255.255.0

• 255.255.255.128

• 255.255.255.192

• 255.255.255.224

What is the smallest subnet mask that can accommodate 60 hosts in a network?

• /25

• /26

• /27

• /28

Which of the following is not a limitation of IPv6 compared to IPv4?

• Limited support by older networking equipment and operating systems.

• Larger header size leading to increased overhead.

• Increased complexity in network management and configuration.

• Exhaustion of available IPv6 addresses due to the vast address space.

Which of the following is an improvement of IPv6 over IPv4?

• Increased broadcast traffic leading to network congestion.

• Simplified header structure reducing packet processing overhead.

• Limited number of available IP addresses due to 32-bit address space.

• Dependency on NAT (Network Address Translation) for private network addressing.
