Final answer:
The failed telnet connection produces more matches to the explicit deny ace than a successful one because it is typically evaluated before the other rules in the access-control list (ACL). This happens because the explicit deny ace is closer to the top of the ACL.
Step-by-step explanation:
The failed telnet connection produces more matches to the explicit deny ace than a successful one because the explicit deny ace is typically closer to the top of the access-control list (ACL), therefore evaluated first. An ACL is a set of rules that determine whether a network packet should be allowed or denied. When a telnet connection fails, it is likely because it violates one of the rules in the ACL, triggering the explicit deny ace.
For example, let's say the explicit deny ace in the ACL specifies that telnet connections from a certain IP address range should be denied. When a telnet connection is attempted from one of those IP addresses, it will match the explicit deny ace and be denied immediately, without further evaluation of the remaining rules. In contrast, a successful telnet connection will not match any explicit deny ace, allowing it to proceed to the next rule in the ACL, which may be an explicit permit ace that allows the connection.
