Question

All other traffic is being dropped due to the ________ ________ rule that applies to all ACLs.

a) Implicit Deny
b) Explicit Allow
c) Permit All
d) Deny All

Answer 1

The correct answer is a) Implicit Deny, which is the default security measure that drops traffic that does not match any permit rules in an Access Control List.

Step-by-step explanation:

All other traffic is being dropped due to the Implicit Deny rule that applies to all Access Control Lists (ACLs). This rule is a fundamental part of network security, ensuring that unless a packet matches an explicit permit rule within the ACL, it will not be allowed through. The ACL checks each packet against its list of rules until it finds a match or reaches the end of the list. If no matches are found, the Implicit Deny rule automatically denies the traffic, which means it will not be forwarded or allowed to pass through the network device enforcing the ACL.
