Cisco CCNA Static and Dynamic Routing Questions and Answers

Question 1

A network administrator is configuring a backup route for a critical network.
The primary route to the 10.10.20.0/24 network is learned via OSPF.
Which command will correctly configure a static route to be used only if the OSPF route becomes unavailable?

Accepted Answer

ip route 10.10.20.0 255.255.255.0 192.168.1.1 120

Answer

ip route 10.10.20.0 255.255.255.0 192.168.1.1 1

Answer

ip route 10.10.20.0 255.255.255.0 192.168.1.1 90

Answer

ip route 10.10.20.0 255.255.255.0 192.168.1.1

Question 2

A router has the following routes in its routing table:
S 192.168.32.0/26 [1/0] via 10.1.1.2
O 192.168.32.0/24 [110/2] via 10.1.1.6
R 192.168.0.0/16 [120/4] via 10.1.1.10

How will the router forward a packet destined for the IP address 192.168.32.63?

Accepted Answer

It will use the static route because it has the longest prefix match.

Answer

It will use the OSPF route because it is a dynamic protocol.

Answer

It will use the RIP route because it covers the largest address range.

Answer

It will load balance across the static and OSPF routes.

Question 3

Which of the following is a primary disadvantage of using static routing exclusively in a large, complex network?

Accepted Answer

Lack of automatic adaptation to network topology changes.

Answer

Lower security compared to dynamic routing protocols.

Answer

Increased router CPU and memory utilization.

Answer

Consumption of network bandwidth by routing updates.

Question 4

A network administrator needs to configure a static route on a router with a multi-access exit interface, such as Ethernet. To avoid potential recursive lookups and ambiguity, the administrator wants to specify both the exit interface and the next-hop IP address. What type of static route is this?

Accepted Answer

Fully specified static route

Answer

Recursive static route

Answer

Directly attached static route

Answer

Floating static route

Question 5

A Cisco router learns about the destination network 172.16.10.0/24 from two different routing sources: internal EIGRP and OSPF. Assuming default settings, which route will be installed in the routing table?

Accepted Answer

The EIGRP route, because it has a lower default administrative distance.

Answer

The OSPF route, because it is an open standard.

Answer

The router will install both routes and load balance the traffic.

Answer

The OSPF route, because it has a lower metric.

Question 6

Which statement accurately describes a key characteristic of dynamic routing protocols like OSPF and EIGRP compared to static routing?

Accepted Answer

They reduce administrative overhead in large networks by automatically learning routes.

Answer

They are best suited for small, simple networks with predictable traffic paths.

Answer

They provide greater security because routes are not advertised over the network.

Answer

They consume no router CPU or memory resources.
