Question

Which address is required in the command syntax of a standard ACL?

a) source MAC address
b) destination MAC address
c) source IP address
d) destination IP address

Answer 1

Answer: C.

Explanation: A standard Access Control List (ACL) is used to filter network traffic based on the source IP address. It allows or denies traffic based on the source IP address specified in the ACL rule. Standard ACLs are typically used to control traffic flow within a network or to filter traffic coming from specific source addresses.

The other options mentioned, such as source MAC address (a) and destination MAC address (b), are typically used in MAC-based filtering or Layer 2 switching. Destination IP address (d) can be used in more advanced ACLs, such as extended ACLs, which provide more granular control by considering additional parameters like source and destination IP addresses, protocols, port numbers, etc. However, in the case of a standard ACL, only the source IP address is used.
