Modul 8

What is the primary purpose of an IPv4 address?

• To identify the physical location of a device.

• To encrypt network traffic.

• To identify a host on a network.

• To manage network security.

How many bits make up each octet in an IPv4 address?

• 4

• 16

• 8

• 32

In an IPv4 address, what is the decimal value of an octet where all 8 bits are 0s (00000000)?

• 1

• 0

• 255

• 128

In an IPv4 address, what is the decimal value of an octet where all 8 bits are 1s (11111111)?

• 0

• 128

• 255

• 256

How is the value of an octet determined when the bits are mixed (e.g., 00100111)?

• By multiplying the values of each bit.

• By dividing the values of each bit.

• By adding the values of the bit positions where there is a binary 1 present.

• By taking the average of all bit values.

What is the purpose of using a logical AND operation with an IPv4 address and subnet mask?

• To encrypt the IP address.

• To convert the IP address to a MAC address.

• To discover the network address.

• To calculate the number of hosts in a network.

What is the primary function of a subnet mask?

• To encrypt the IP address.

• To identify the physical location of a device.

• To signify which part of the IPv4 address is network and which part is host.

• To provide a default gateway.

If the network bits of the source and destination hosts match, where will the packet be delivered?

• To a remote router.

• Locally on the same network.

• To a public cloud server.

• Through the internet

What happens if the network bits of the source and destination hosts do not match?

• The packet is discarded.

• The packet is sent to the local server.

• The packet is forwarded to the local router interface.

• The packet is resent to the sending host.

Which of the following is NOT a common subnet mask?

• 255.0.0.0

• 255.255.0.0

• 255.255.255.255

• 255.255.255.0
