CCNA 2 Module 14 test

On a network that commonly experiences topology changes.

On which type of network would a dynamic routing protocol be implemented in?

The static route is removed from the routing table.

R1 is configured with the ip route 10.1.0.0 255.255.0.0 g0/0/0 command. What happens if the G0/0/0 interface goes down?

The G0/0/0 interface has not been activated.

A network administrator configures the G0/0/0 interface with the ip address 10.1.1.0 255.255.255.0 command. However, when the administrator issues the show ip route command, the routing table does not show the directly connected network. What is the possible cause of the problem?

S 172.16.1.0 [1/0] via 172.16.2.2

The network administrator configures the router with the ip route 172.16.1.0 255.255.255.0 172.16.2.2 command. How will this route appear in the routing table?

administrative distance

The output of the show ip route command contains the following entry: S 10.2.0.0 [1/0] via 172.16.2.2. What value is indicated by the 1 in the [1/0] portion of the output?

::/0 Explanation: The IPv6 address and prefix for a default static route is ::/0. This represents all zeros in the address and a prefix length of zero.

What address and prefix length is used when configuring an IPv6 default static route?

Static routing is more secure because it does not advertise routes to other routers. Static routing uses fewer router resources than dynamic routing.

What are two advantages of static routing over dynamic routing? (Choose two.)

a static route to a specific network a default static route

What are two common types of static routes in routing tables? (Choose two)

A router connects multiple IP networks. It determines the best path to send packets.

What are two functions of a router? (Choose two.)

to discover the network to maintain routing tables

What are two functions of dynamic routing protocols? (Choose two.)

Static routing uses less router processing and bandwidth. Static routing is more secure.

What are two reasons why an administrator might choose to use static routing rather than dynamic routing? (Choose two.)

ability to actively search for new routes if the current path becomes unavailable

What is an advantage of using dynamic routing protocols instead of static routing?

Default static route

What static route identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned route?

default route

What type of route allows a router to forward packets even though its routing table contains no specific route to the destination network?

the lowest metric

When a router learns that multiple paths are available to a destination network from the same routing protocol, which factor is considered by a router to choose the best path to forward a packet?

gateway of last resort

Which feature on a Cisco router permits the forwarding of traffic for which there is no specific route?

Cisco Express Forwarding

Which packet-forwarding method does a router use to make switching decisions when it is using a forwarding information base and an adjacency table?

Static routing does no advertise over the network, thus providing better security. The path a static route uses to send data is known. Static routing typically uses less network bandwidth and fewer CPU operations than dynamic routing does.

Which three advantages are provided by static routing? (Choose three.)

C L

Which two route source codes are automatically created within a routing table whenever a router interface is configured with an IP address and activated? (Choose two.)

default

Which type of route would typically be used on a border router so that devices inside the company could access the Internet?

default static route

Which type of static route creates a gateway of last resort?

metric

Which value in a routing table is used to compare routes received from a routing protocol?

Administrative distance

Which value represents the "trustworthiness" of a route and is used to determine which route to install into the routing table when there are multiple routes toward the same destination?
