CIT 116 Review Module 14-16

Which two route sources have the ability to automatically discover a new best path when there is a change in the topology? (Choose two.)

1. OSPF 2. EIGRP

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

1. Static routing does not advertise over the network, thus providing better security. 2. Static routing typically uses less network bandwidth and fewer CPU operations than dynamic routing does. 3. The path a static route uses to send data is known.

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

1. Static routing is more secure because it does not advertise over the network. 2. Static routing uses fewer router resources than dynamic routing

Which of the following routes may be found in a routing table? (Choose all that apply.)

1. directly connected networks 2. static routes 3. dynamic routing protocol router 4. default route

On which two routers would a default static route be configured? (Choose two.)

1. stub router connection to the rest of the corporate or campus network 2. edge router connection to the ISP

What two pieces of information are needed in a fully specified static route to eliminate recursive lookups? (Choose two.)

1. the interface ID exit interface 2. the IP address of the next-hop neighbor

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

1. to maintain routing tables 2. to discover the network

Which two methods can be used to identify the next hop in a static route? (Choose two.)

1.destination IP address 2. exit interface

An administrator issues the ipv6 route 2001:db8:acad:1::/32 gigabitethernet0/0 2001:db8:acad:6::1 100 command on a router. What administrative distance is assigned to this route?

100

What network prefix and prefix-length combination is used to create a default static route that will match any IPv6 destination?

::/0

Which route would be used to forward a packet with a source IP address of 192.168.10.1 and a destination IP address of 10.1.1.1?

O 10.1.1.0/24 [110/65] via 192.168.200.2, 00:01:20, Serial0/1/0

Ipv6 route 2001:0DB8::/32 2001:0DB8:3000::1Which static route is configured here?

Recursive static

Which routing table principle is not correct?

Routing information about a path from one network to another also provides routing information about the reverse, or return path.

A network administrator configures a static route for the same destination network that was learned automatically by the router using OSPF. Which route will be installed and why?

Static route because it has a lower administrative distance

What type of network is accessed by a single route and the router has only one neighbor?

Stub network

A network administrator configures the interface fa0/0 on the router R1 with the command ip address 172.16.1.254 255.255.255.0 . However, when the administrator issues the command show ip route , the routing table does not show the directly connected network. What is the possible cause of the problem?

The interface fa0/0 has not been activated

What is used to determine the minimum number of far-left bits that must match between the prefix in the route entry and the destination IP address.

prefix length in the routing table entry

What table does a router use to determine how to forward an IP packet?

routing table

What type of routing is typically used with a stub network?

static routes

What characteristic completes the following statement?When an IPv6 static route is configured, it is first necessary to configure ......

the "ipv6 unicast-routing" command.

What characteristic completes the following statement?When an IPv6 static route is configured, the installation of the route can be verified with ......

the "show ipv6 route static" command.

Which packet forwarding method is used by default on Cisco routers?

Cisco Express Forwarding

True or False? A default route can only be a static route.

FALSE

What is a characteristic of a static route that matches all packets?

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

What is a characteristic of a floating static route?

It is configured with a higher administrative distance than the original dynamic routing protocol has.

What action will a router take on a packet with a destination IP address that is on a remote network?

It will forward the packet to a next-hop router

Which route entry would be used for a packet with a destination IP address that matches an IP address of one of the router interfaces?

L for Local

Consider the following command: ip route 192.168.10.0 255.255.255.0 10.10.10.2 5 How would an administrator test this configuration?

Manually shut down the router interface used as a primary route

A network administrator configures the interface fa0/0 on the router R1 with the command ip address 172.16.1.254 255.255.255.0. However, when the administrator issues the command show ip route, the routing table does not show the directly connected network. What is the possible cause of the problem?

The interface fa0/0 has not been activated

What happens to a static route entry in a routing table when the outgoing interface associated with that route goes into the down state?

The static route is removed from the routing table.

If a router needs to send an ARP Request for the IPv4 address in one of its route entries, this means the packet will be forwarded:

To a next-hop router

If a router needs to send an ARP Request for the destination IPv4 address of the packet, this means the packet will be forwarded:

To the device with the destination IPv4 address of the packet

How is the destination network in an IPv6 static route identified?

Using an IPv6 prefix and prefix length

What characteristic completes the following statement?When an IPv6 static route is configured, a fully-specified configuration should be used with ...

a directly connected multiaccess network.

What route would have the lowest administrative distance?

a directly connected network

Consider the following command: ip route 192.168.10.0 255.255.255.0 10.10.10.2 5 Which route would have to go down in order for this static route to appear in the routing table?

a static route to the 192.168.10.0/24 network

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

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

Consider the following command: ip route 192.168.10.0 255.255.255.0 10.10.10.2 5 What does the 5 at the end of the command signify?

administrative distance

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

What characteristic completes the following statement?When an IPv6 static route is configured, as a backup route to a static route in the routing table, the "distance" command is used with ......
