An ACL is applied inbound on a router interface. The ACL consists of a single entry: access-list 101 permit udp 192.168.100.32 0.0.0.7 host 198.133.219.76 eq telnet . If a packet with a source address of 198.133.219.100, a destination address of 198.133.219.170, and a protocol of 23 is received on the interface, is the packet permitted or denied?

access-list 101 permit udp 192.168.100.32 0.0.0.7 host 198.133.219.76 eq telnet .
If a packet with a source address of 198.133.219.100, a destination address of 198.133.219.170, and a protocol of 23 is received on the interface, is the packet permitted or denied?
permitted
denied
Explanation:
Parameter Mismatch: The incoming packet fails to match the single Access Control Entry (ACE) on multiple fields. Specifically, its source address (198.133.219.100) and destination address (198.133.219.170) do not match the ACE's required source (192.168.100.32 0.0.0.7) and host destination (198.133.219.76).
Implicit Deny: According to the sources, when a packet does not match any defined ACE in a list, it is automatically discarded due to the implicit deny any statement that is present at the end of every ACL. Because this packet matches no permit criteria, it is denied.
