PAP uses MD5 hashing to keep the password secure. 17

What is a common use of a TFTP server? to allow access to restricted system resources

to detect attacks against a network and send logs to a management console to provide active defense mechanisms that prevent attacks against the network to perform IOS image and configuration uploads and downloads over the network 18

Refer to the exhibit. The link between the CTRL and BR_1 routers is

configured as shown in the exhibit. Why are the routers unable to establish a PPP session?

The clock rate must be 56000. The usernames are misconfigured. The IP addresses are on different subnets.

The clock rate is configured on the wrong end of the link. The CHAP passwords must be different on the two routers.

Interface serial 0/0/0 on CTRL must connect to interface serial 0/0/1 on BR_1. 19

What is the result when the command security passwords min-length 8 is entered into a router?

All new passwords are required to be a minimum of 8 characters in length.

All current passwords are now required to be a minimum of 8 characters in length. Enable passwords must be at least 8 characters but line passwords are unaffected.

Nothing will happen until the command service password-encryption is entered. Then all future passwords must have a minimum of 8 characters.

One access list per port, per protocol, per direction is permitted. Access list entries should filter in the order from general to specific.

Statements are processed sequentially from top to bottom until a match is found.

The term “inbound” refers to traffic entering the network from the router interface where the ACL is applied.

Standard ACLs should be applied closest to the source while extended ACLs should be applied closest to the destination.

23

A network technician wants to implement SSH as the means by which a router may be managed remotely. What are two procedures that the technician should use to successfully complete this task? (Choose two.)

Configure the login banner. Configure authentication. Define the asymmetrical keys. Configure the console password.

What will be the result of adding the command ip dhcp excluded-address 192.168.24.1 192.168.24.5 to the configuration of a local router that has been configured as a DHCP server?

Traffic that is destined for 192.168.24.1 and 192.168.24.5 will be dropped by the router. Traffic will not be routed from clients with addresses between 192.168.24.1 and 192.168.24.5.

The DHCP server will not issue the addresses ranging from 192.168.24.1 to 192.168.24.5. The router will ignore all traffic that comes from the DHCP servers with addresses 192.168.24.1 and 192.168.24.5.

26

Refer to the exhibit. The network administrator creates a standard access control list to prohibit traffic from the 192.168.1.0/24 network from reaching the Internet. The access list must still permit the 192.168.1.0/24 network access to the 192.168.2.0 network. On which router interface and in which direction should the access control list be applied?

interface Fa0/0, inbound interface Fa0/0, outbound interface S0/0/0, inbound interface S0/0/0, outbound 27

(10)

Refer to the exhibit. Which statement is true about the Frame Relay connection?

The Frame Relay connection is in the process of negotiation.

A congestion control mechanism is enabled on the Frame Relay connection. The “ACTIVE” status of the Frame Relay connection indicates that the network is experiencing congestion.

Only control FECN and BECN bits are sent over the Frame Relay connection. No data traffic traverses the link.

28

Refer to the exhibit. Results of the show vlan and show vtp status commands for switches S1 and S2 are displayed in the exhibit. VLAN 11 was created on S1. Why is VLAN 11 missing from S2?

There is a Layer 2 loop.

The VTP domain names do not match. Only one switch can be in server mode.

(11)

29
