How many IP assignable addresses are contained in 10.0.128.0/23?

  1. 4094
  2. 254
  3. 510
  4. 512

Answer(s): C

Explanation:

The subnet 10.0.128.0/23 has a subnet mask of 255.255.254.0. This means that the network portion of the address is 10.0.128.0 and the host portion ranges from 0 to 255 in the last octet.

The formula to calculate the number of assignable IP addresses in a subnet is 2^(number of host bits) - 2. In this case, there are 9 host bits (32 - 23 = 9), so the calculation would be:

2^9 - 2 = 510

Therefore, the answer is C. There are 510 assignable IP addresses in the subnet 10.0.128.0/23.



What is a characteristic of IPv4 addresses?

  1. It is 32 bits long
  2. It is 128 bits long
  3. 12 hex-digit notation
  4. Has zero compression rule

Answer(s): A

Explanation:

IPv4 addresses are 32-bit addresses that are used to identify devices on a network. Each IPv4 address consists of four octets (8-bit values) separated by dots, such as 192.168.0.1.

IPv6, on the other hand, is 128 bits long and uses a hexadecimal notation with colons separating the 16-bit values. IPv6 addresses are designed to address the limitations of IPv4, including address exhaustion and security concerns.

Zero compression is a characteristic of IPv6 addresses, not IPv4. IPv6 allows multiple consecutive groups of zeros to be represented with a double colon (::), reducing the length of the address. IPv4 does not have this feature.



How many addresses does the 255.255.252.0 provide?

  1. 16384
  2. 32768
  3. 8192
  4. 1024

Answer(s): D

Explanation:

The subnet mask 255.255.252.0 is a /22 subnet mask, which means that it has 22 network bits and 10 host bits.

To calculate the number of IP addresses provided by this subnet mask, we need to use the formula 2^(number of host bits) - 2. In this case, we have:

2^(10) - 2 = 1024 - 2 = 1022

Therefore, the subnet mask 255.255.252.0 provides 1022 assignable IP addresses. The answer is not one of the options provided, but the closest answer is D.



Which OSI model layer is in charge of creating data?

  1. Physical
  2. Transport
  3. Layer 4
  4. Layer 7

Answer(s): D

Explanation:

Data creation is not a specific function of any layer in the OSI model. The application layer, which is Layer 7, is responsible for providing services to the user, including data creation, data representation, and data manipulation.

However, it is important to note that data can be created and modified at various layers in the OSI model. For example, at the transport layer (Layer 4), the source and destination ports are added to the data to create a segment. At the network layer (Layer 3), the source and destination IP addresses are added to the data to create a packet.

Therefore, while the application layer is primarily responsible for creating data, data can be modified or created at various layers in the OSI model.
