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

Accepted Answer

Conserving IP addresses

Answer

Enhancing network performance

Answer

Providing additional security

Answer

Balancing network load

Question 4

What is the fundamental difference between a static IP address and a dynamic IP address?

Accepted Answer

Static IP addresses are manually configured, while dynamic IP addresses are assigned by a DHCP server.

Answer

Dynamic IP addresses are more secure than static IP addresses.

Answer

Static IP addresses are exclusively used for servers, while dynamic IP addresses are for workstations.

Answer

There is no difference between static and dynamic IP addresses.

Question 5

On a Windows system, which command is used to display the IP configuration?

Accepted Answer

ipconfig

Answer

ifconfig

Answer

netstat

Answer

route print

Question 6

How do you manually configure IP addresses on a network interface, and how does DHCP automate this process?

Accepted Answer

Manually assign an IP address, subnet mask, and default gateway to the interface.

Accepted Answer

Configure DHCP on the interface to automatically obtain IP address information.

Answer

Use ARP to resolve the MAC address associated with the interface and assign an IP address based on that.

Answer

Configure the router as the DHCP server to assign IP addresses to all connected devices.

Question 7

What is the purpose of a subnet mask?

Accepted Answer

To separate the network portion of an IP address from the host portion.

Answer

To translate IP addresses into MAC addresses.

Answer

To determine the default gateway.

Answer

To encrypt network traffic.

Question 15

What is the default subnet mask length for an IPv6 address?

Accepted Answer

/64

Answer

/128

Answer

/192

Answer

/256

Question 16

What is the primary purpose of the 'ping' command?

To test network connectivity

Answer

To resolve DNS names

Answer

To trace the route of a packet

Answer

To troubleshoot network problems

Question 17

How does variable-length subnet masking (VLSM) differ from traditional subnetting?

Accepted Answer

VLSM uses different subnet mask lengths for different subnetworks, making IP address allocation more efficient.

Answer

VLSM requires a more complex hierarchical addressing structure.

Answer

VLSM is only used for IPv6 addressing and not for IPv4 networks.
