Which of the following is correct for the destination address 4A : 30 : 10 : 21 : 10 : 1A?

Correct option is A

A unicast address is a unique identifier for a single network interface. The given address, 4A:30:10:21:10:1A, follows the format of a unicast MAC address, which is used for point-to-point communication between devices in a network.
Information Booster
1. Unicast Address: Used for communication between one sender and one receiver. The given MAC address is an example of this.
2. Multicast Address: Used for communication between one sender and multiple receivers. It starts with specific reserved prefixes (e.g., addresses with the least significant bit of the first byte set to 1).
3. Broadcast Address: Used for communication with all devices in the network. For Ethernet, it is typically FF:FF:FF:FF:FF:FF.
4. Identification: Unicast MAC addresses typically have the least significant bit of the first byte set to 0.
Additional Knowledge
· MAC addresses are 48-bit identifiers assigned to network interfaces.
· Multicast addresses allow efficient delivery to multiple devices without duplication at the sender level.
· Broadcast addresses are limited to local networks and do not traverse routers.
