Ccna Chapter 5

Front 1

In an IPv4 environment, what information is used by the router to forward data packets from one interface of a router to another?

Back 1

destination network address

Front 2

What information is added during encapsulation at OSI Layer 3?

Back 2

source and destination IP address

Front 3

In a connectionless system, which of the following is correct?

Back 3

The destination is not contacted before a packet is sent.

Front 4

Which IP packet field will prevent endless loops?

Back 4

time-to-live

Front 5

Which portion of the network layer address does a router use to forward packets?

Back 5

network portion

Front 6

Refer to the exhibit. Using the network in the exhibit, what would be the default gateway address for host A in the 192.133.219.0 network?

Back 6

192.133.219.1

Front 7

If the default gateway is configured incorrectly on the host, what is the impact on communications?

Back 7

The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks.

Front 8

What is the purpose of a default gateway?

Back 8

identifies the device that allows local network computers to communicate with devices on other networks

Front 9

What type of routing uses information that is manually entered into the routing table?

Back 9

static

Front 10

When the destination network is not listed in the routing table of a Cisco router, what are two possible actions that the router might take? (Choose two.)

Back 10

The router discards the packet.

The router forwards the packet out the interface indicated by the default route entry.

Front 11

What are the key factors to consider when grouping hosts into a common network? (Choose three.)

Back 11

purpose

geographic location

ownership

Front 12

What is a component of a routing table entry?

Back 12

the next-hop address

Front 13

Which intermediary devices could be used to implement security between networks? (Choose two.)

Back 13

router

firewall

Front 14

What are three common problems with a large network? (Choose three.)

Back 14

performance degradation

security issues

host identification

Front 15

Refer to the exhibit. All devices shown in the exhibit have factory default settings. How many broadcast domains are represented in the topology that is shown?

Back 15

4

Front 16

Which three statements are true about routes and their use? (Choose three.)

Back 16

If the destination network is directly connected, the router forwards the packet to the destination host.

If no route exists for the destination network and a default route is present, the packet is forwarded to the next-hop router.


If the originating host has a default gateway configured, the packet for a remote network can be forwarded using that route.

Front 17

Refer to the exhibit. A network administrator notices that there are too many broadcasts on the network. What two steps can the network administrator take to resolve this problem? (Choose two.)

Back 17

Replace S2 with a router.

Subnet the 192.168.0.0 /24 network.

Front 18

Refer to the exhibit. The network in the exhibit is fully operational. What two statements correctly describe the routing for the topology that is shown? (Choose two.)

Back 18

192.168.0.2 is the next-hop address that is used by R3 to route a packet from the 10.0.0.0 network to the 172.16.0.0 network.

192.168.0.1 is the next-hop address that is used by R2 to route a packet from the 172.16.0.0 network to the 192.168.12.0 network.

Front 19

What two characteristics are commonly associated with dynamic routing protocols? (Choose two.)

Back 19

provide routers with up-to-date routing tables

consume bandwidth to exchange route information

Front 20

What statement describes the purpose of a default route?

Back 20

A host uses a default route to transfer data to a host outside the local network when no other route to the destination exists.
