Quiz 9

In applying an ACL to a router interface, which traffic is designated as outbound?

traffic that is leaving the router and going toward the destination host

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?

10.120.160.0 to 10.120.167.255

This ACL is applied on traffic outbound from the router on the interface that directly connects to the 10.0.70.5 server. A request for information from a secure web page is sent from host 10.0.55.23 and is destined for the 10.0.70.5 server. Which line of the access list will cause the router to take action (forward the packet onward or drop the packet)?

3

Which command is used to activate an IPv6 ACL named ENG_ACL on an interface so that the router filters traffic prior to accessing the routing table?

ipv6 traffic-filter ENG_ACL in

In the creation of an IPv6 ACL, what is the purpose of the implicit final command entries, permit icmp any any nd-na and permit icmp any any nd-ns?

to allow IPv6 to MAC address resolution

Refer to the exhibit. A network administrator is configuring a standard IPv4 ACL. What is the effect after the command no access-list 10 is entered?

ACL 10 is removed from the running configuration.

Which two statements are correct about extended ACLs? (Choose two)

Extended ACLs evaluate the source and destination addresses. Answer Port numbers can be used to add greater definition to an ACL.

Which series of commands will cause access list 15 to restrict Telnet access on a router?

R1(config)# line vty 0 4 R1(config​-line)# access-class 15 in

A network administrator wants to create a standard ACL to prevent network 1 traffic from being transmitted to the Research and Development network. On which router interface and in which direction should the standard ACL be applied?

R2 Gi0/0 outbound

A network administrator configures a named ACL on the router. Why is there no output displayed when the show command is issued?

The ACL name is case sensitive.

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?

The IT group network is included in the deny statement.

Refer to the exhibit. What can be determined from this output?

The router has not had any Telnet packets from 10.35.80.22 that are destined for 10.23.77.101.

Which set of access control entries would allow all users on the 192.168.10.0/24 network to access a web server that is located at 172.17.80.1, but would not allow them to use Telnet?

access-list 103 permit tcp 192.168.10.0 0.0.0.255 host 172.17.80.1 eq 80 access-list 103 deny tcp ​192.168.10.0 0.0.0.255 any eq 23

What is the effect of the established parameter in an extended ACL?

allows external traffic into a network only if it is part of an existing connection with an internal host
