top-down

bottom-up

substitution

divide-and-conquer

11

Although all networks are reachable, the network administrator notices abnormal routing behavior after

configuring OSPF on each router. According to the partial output from the debug ip ospf events command,

which statement is true about the contents of the routing table in RA?

It will show network 172.16.3.0 learned from RB.

It will show network 172.16.3.0 learned from RC.

It will show two equal routes to network 192.168.1.4/30.

It will show two equal routes to network 192.168.1.8/30.

12 A network at a large building failed, causing a severe disruption in business activities. The problem was

eventually detected and resolved by replacing a piece of failed network equipment. Investigation led to the

conclusion that a network design problem was the main cause of the disruption. Loss of a single piece of

equipment should not have been able to cause such a large problem. What two terms best describe this type of

design weakness? (Choose two.)

bottleneck

limited availability

limited scalability

large failure domain

single point of failure

limited staff capabilities

13

Refer to the exhibit. The network administrator is unable to ping from the console of router R3 to host

10.10.4.63. What is the problem?

RIPv1 does not support VLSM.

Router R2 does not have RIP correctly configured.

Router R3 is missing a network statement for network 10.0.0.0.

There is an addressing problem on the link between routers R2 and R3.

14 What is important to consider while configuring the subinterfaces of a router when implementing inter-VLAN

routing?

The subinterface numbers must match the VLAN ID number.

The physical interface must have an IP address configured.

The IP address of each subinterface must be the default gateway address for each VLAN subnet.

The no shutdown command must be given on each subinterface.

15

Refer to the exhibit. Users are reporting that they cannot access the Internet. Routers R1 and R2 are configured

with RIP version 2 as shown. If R2 receives a packet with a destination address on the Internet, how is the packet

routed?

The packet is routed to the ISP router and then to network 10.1.1.0/24.

The packet is routed to the ISP router and then to the Internet.

The packet is routed to R1 and then forwarded out Fa0/0 on R1.

The packet will not be routed because R2 does not have a valid default route.

Refer to the exhibit. An ACL is configured to prevent access by network 192.168.1.0 to network 192.168.2.0,

but it is not working properly. What problem is discovered after observing the output of the show running-

config command?

The protocol type specified in the ACL should be TCP, not IP.

The source and destination addresses are reversed in the statement.

The ACL is applied to the wrong interface, but the right direction.

The ACL is applied to the wrong interface and the wrong direction.

The permit ip any any statement allows network 192.168.1.0 access.

17

Refer to the exhibit. Host 192.168.1.14 is unable to download email from 192.168.2.200. After reviewing the

output of the show running-config command, what problem is discovered?

The destination host address in an ACL statement is incorrect.

The ACL is applied to the interface in the wrong direction.

The implicit deny any any is blocking all access to email.

18

Refer to the exhibit. Both routers are configured using RIPv1. Both routers are sending updates about the

directly connected routes. R1 can successfully ping the serial interface of R2. The routing table on R1 does not

contain any dynamically learned routes from R2, and the routing table on R2 shows no dynamically learned

routes from R1. What is the problem?

Subnetting is not supported by RIPv1.

One of the routers needs a clock rate on the serial interface.

The serial link between the two routers is unstable.
