Which range represents all the IP addresses that are affected when network 10.120.160.0 with a
wildcard mask of 0.0.7.255 is used in an ACE? Answer: 10.120.160.0 to 10.120.167.255
What two functions describe uses of an access control list? Answer: -ACLs provide a basic level of
security for network access.
-ACLs can control which areas a host can access on a network.
Which two statements describe the effect of the access control list wildcard mask 0.0.0.15? Answer:
-The last four bits of a supplied IP address will be ignored.
-The first 28 bits of a supplied IP address will be matched.
Refer to the exhibit. A network administrator is configuring an ACL to limit the connection to R1 vty lines
to only the IT group workstations in the network 192.168.22.0/28. The administrator verifies the
successful Telnet connections from a workstation with IP 192.168.22.5 to R1 before the ACL is applied.
However, after the ACL is applied to the interface Fa0/0, Telnet connections are denied. What is the
cause of the connection failure? Answer: The IT group network is included in the deny statement.
Refer to the exhibit. The network administrator that has the IP address of 10.0.70.23/25 needs to have
access to the corporate FTP server (10.0.54.5/28). The FTP server is also a web server that is accessible
to all internal employees on networks within the 10.x.x.x address. No other traffic should be allowed to
this server. Which extended ACL would be used to filter this traffic, and how would this ACL be applied?
Answer: -access-list 105 permit tcp host 10.0.70.23 host 10.0.54.5 eq 20
