Post-Test: Pengenalan Alamat IPv4

What is the main function of an IP address in a computer network?

• Store user data

• Provide Wi-Fi connection

• Uniquely identify devices

• Store network configuration

IPv4 addresses are written in which format?

• Hexadecimal

• Dotted decimal

• Pure binary

• Octal

How many bits make up a single IPv4 address?

• 8 bits

• 16 bits

• 32 bits

• 64 bits

The range of IP addresses for class C is:

• 1.0.0.0 - 127.255.255.255

• 128.0.0.0 - 191.255.255.255

• 192.0.0.0 - 223.255.255.255

• 224.0.0.0 - 239.255.255.255

What class does the IP address 192.168.1.1 belong to?

• A

• B

• C

• D

In the structure of an IPv4 address, the part that determines the network is called:

• Host ID

• Subnet ID

• Network prefix

• IP Gateway

Subnetting is used for:

• Expanding the network

• Dividing a large network into smaller networks

• Automatically changing IP addresses

• Reducing network speed

The main benefits of subnetting are as follows, except:

• Address efficiency

• Improving security

• Speeding up the encryption process

• Reducing broadcast

The IP address 11000000.10101000.00000001.00000001 in decimal is:

• 128.10.1.1

• 255.255.255.0

• 192.168.1.1

• 10.0.0.1

What is the maximum decimal value in a single IPv4 octet?

• 127

• 255

• 512

• 1024
