What are two characteristics of an extended ACL? (Choose two.) IP is used to specify TCP traffic only. IP is used to specify TCP and UDP traffic only. IP is used to specify all TCP/IP protocols including TCP, UDP, ICMP and routing protocols. Traffic can be filtered on source address only. Traffic can be filtered on source and destination address only. Traffic can be filtered on source and destination address, protocol, and specific port number.

RB has the lowest priority value. RC and RD have the lowest router IDs on the network. RA has established adjacencies with all neighbor routers. RA and RB cannot form an adjacency because they are stuck in the 2-way state.

Router B has not formed an adjacency with router C.

Refer to the exhibit. A network support technician has been asked to set an IP address on one of the FastEthernetinterfaces on a new router. What is causing the interface to reject the address? The IP address is already in use. The technician is using a network address. The technician is using the wrong subnet mask for /26 The technician must enable VLSM on the interface.

Refer to the exhibit. A network administrator enters the command ip route 10.10.4.16 255.255.255.248 s0/0/1 intothe router. What will be the result of this configuration? A static route pointing to 10.10.4.16/29 is placed into the routing table. A static route to 10.10.4.16/29 is placed into the routing table if interface FastEthernet0/1 goes down.

A static route pointing to 10.10.4.16/29 is only placed into the routing table if the route to 10.10.4.0 is removed. A static route is not placed into the routing table because a RIP route that includes the destination networkalready exists.

Refer to the exhibit. Server7 has been added to the server farm network. The hosts can ping Servers 2 and 3 andServer2 and Server3 can ping each other. Server7 cannot ping the other servers connected to the switch. What isthe cause of this problem? The Fa0/1 port on the switch should be in access mode. The switch IP address is not on the same subnet as Server7. The switch port used for Server7 is not in the same VLAN as Server2 and Server3. The Fa0/0 interface of the router has not been configured for subinterfaces to support inter-VLAN routing.

Refer to the exhibit. A network administrator must manually summarize all IP addresses on the POP router for the

ISP. Which one is the correct summary address?

192.168.0.0/22

Refer to the exhibit. What two pieces of information can be gathered from the output of this command? (Choose

two.)

172.16.16.0/20 is a manually summarized route.

All subnets are being advertised because default summarization was disabled.

The output verifies that EIGRP is advertising only the networks in the same AS.

The 172.16.1.0/24 network is directly attached to the router that produced this output.

The Null0 interface indicates that this is not an actual path, but a summary for advertising purposes.

Refer to the exhibit. What three facts represent the result of DR and BDR elections in this OSPF network?

(Choose three.)

RTC will be the DR of 10.5.0.0/30

RTD will be the BDR of 10.5.0.0/30.

RTD will be the DR of 10.4.0.0/28.
http://lh5.ggpht.com/amnaj.suksamai/SP8GycSMebI/AAAAAAAAAgQ/MjccDZotg2s/7%5B4%5D.jpghttp://lh3.ggpht.com/amnaj.suksamai/SP8GojSpNjI/AAAAAAAAAgI/7hv3jDSl1_c/4%5B3%5D.jpg


12/14

RTB will be the BDR of 10.7.0.0/28.

RTB will be the DR of 10.7.0.0/28.

RTA will be the BDR of 10.4.0.0/28.

Refer to the exhibit. Internet access is crucial for the company network shown. Internet access is provided by two

ISPs. ISP1 is the primary provider and ISP2 is the backup provider. The network administrator configures BorderR

as the border router so that in normal operations, all Internet traffic goes through ISP1. However, if the link to ISP1

fails, then BorderR will automatically forward Internet traffic to ISP2. The administrator configures two default

routes:

BorderR(config)# ip route 0.0.0.0 0.0.0.0 192.168.100.1 200

BorderR(config)# ip route 0.0.0.0 0.0.0.0 172.16.1.1

However, when the administrator issued the show ip route command to verify the configuration, only the second

default route is in the routing table. Why is the first default route not showing?

The first configuration command overwrites the second command.

The first default route will be installed into the routing table if there is traffic with an IP address that is destined for

the 192.168.100.0 network.

This is expected because the link to ISP1 is active. If the link to ISP1 goes down, then the first default route will

be installed into the routing table.

The first default route cannot be installed into the routing table unless the administrator manually disables thesecond default route with the no ip route 0.0.0.0 0.0.0.0 172.16.1.1 command.
