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

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? (Choose
two.) Answer: The first 28 bits of a supplied IP address will be matched.
The last four bits of a supplied IP address will be ignored.
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.
Two routers, R1 and R2, connect via a serial link. Both the R1 and R2 interfaces that connect to this
network are labeled S0/0/0. Above the serial link are the words 10.0.56.252/30. R1 has two more
connections: Gi0/0 and Gi0/1. The Gi0/0/ R1 interface connects to a switch. That switch connects to a
server labeled FTP and web server 10.0.54.5/28. The R1 Gi0/1 interface connects to a switch. That
switch connects to a host. Under the host are the words 10.0.55.23/24. The R2 router has another
interface labeled Gi0/0. This interface connects to a switch. That switch connects to a host. Under the
host are the words 10.0.70.23/25.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
