What is the result of applying the access-list to Ethernet 0?
A. Only e-mail and telnet access will be permitted out of Ethernet 0.
B. All hosts on the 172.30.24.64 network will be permitted e-mail and telnet access.
C. All TCP protocols will be permitted out of Ethernet 0 except e-mail and telnet.
D. All IP traffic out of Ethernet 0 will be denied.
E. The access-list is numbered incorrectly and will fail.
Answer: D
Explanation: The exhibit is showing an extended IP access-list configuration. For this access list to have the
desired effect it will require a permit statement at the end as there is an implicit deny statement otherwise. The
statement should be: access-list 105 permit ip any any.
Incorrect Answers:
A, B and C are incorrect; all traffic out will be denied without a permit statement.
E is incorrect; the access-list is correctly numbered.
