Cisco CCNA 2 Chapter 3 Cisco Exam Answers 100%

> Refer to the exhibit. Based on the partial output from the show ip route command, what two facts can be determined about the RIP routing protocol?. (Choose two).

RIP version 1 is running on this router and its RIP neighbor.

RIP version 2 is running on this router and its RIP neighbor.*

The metric to the network 172.16.0.0 is 120.

The command no auto-summary has been used on the RIP neighbor router.*

RIP will advertise two networks to its neighbor.

> What is the purpose of the passive-interface command?.

Allows an interface to remain up without receiving keepalives.

Allows interfaces to share IP addresses.

Allows a router to receive routing updates on an interface but not send updates via that interface.*

Allows a router to send routing updates on an interface but not receive updates via that innterface.

Allows a routing protocol to forward updates out an interface that is missing its IP address.

> What two actions result from entering the network 192.168.1.0 command in RIP configuration mode on a router?. (Choose two).

The routing table is created in the RAM of the router.

The network address 192.168.1.0 is advertised to the neighbor routers.*

Routing updates are sent through all the interfaces belonging to 192.168.1.0.*

The RIP process is stopped and all existing RIP configurations are erased.

The neighboring routers are sent a request for routing updates.

> Match the characteristic to the corresponding type of routing. (Not All Options Are Used).

> Refer to the exhibit. Which interface will be the exit interface to forward a data packet with the destination IP address 172.16.0.66?.

Serial0/0/0.

GigabitEthernet0/1.

GigabitEthernet0/0.

Serial0/0/1.*

> What is different between IPv6 routing table entries compared to IPv4 routing table entries?.

IPv6 does not use static routes to populate the routing table as used in IPv4.

The selection of IPv6 routes is based on the shortest matching prefix, unlike IPv4 route selection which is based on the longest matching prefix.

IPv6 routing tables include local route entries which IPv4 routing tables do not.

By design IPv6 is classless so all routes are effectively level 1 ultimate routes.*

> Which dynamic routing protocol was developed as an exterior gateway protocol to interconnect different Internet providers?.

BGP.*

OSPF.

EIGRP.

RIP.

> A destination route in the routing table is indicated with a code D. Which kind of route entry is this?.

A route used as the default gateway.

A network directly connected to a router interface.

A route dynamically learned through the EIGRP routing protocol.*

A static route.

> Which two requirements are used to determine if a route can be considered as an ultimate route in a router’s routing table?. (Choose two).

Contain subnets.

Be a classful network entry.

Contain a next-hop IP address.*

Be a default route.

Contain an exit interface.*

> Match the features of link-state routing protocols to their advantages and disadvantages. (Not All Options Are Used).

> What two tasks do dynamic routing protocols perform?. (Choose two).

Network discovery.*

Update and maintain routing tables.*

Discover hosts.

Propagate host default gateways.

Assign IP addressing.

> Which two events will trigger the sending of a link-state packet by a link-state routing protocol?.(Choose two).

The requirement to periodically flood link-state packets to all neighbors.

A change in the topology.*

The initial startup of the routing protocol process.*

The router update timer expiring.

A link to a neighbor router has become congested.

> Which two statements describe the OSPF routing protocol?. (Choose two).

Automatically summarizes networks at the classful boundaries.

Used primarily as an EGP.

Uses Dijkstra’s algorithm to build the SPF tree.*

Has an administrative distance of 100 calculates its metric using bandwidth.*

> Refer to the exhibit. OSPF is used in the network. Which path will be chosen by OSPF to send data packets from Net A to Net B?.

R1, R4, R6, R7.

R1, R3, R6, R7.

R1, R3, R5, R6, R7.

R1, R2, R5, R7.

R1, R3, R5, R7.*

> Which route is the best match for a packet entering a router with a destination address of 10.16.0.2?.

S 10.0.0.0/16 is directly connected, Ethernet 0/0.

S 10.16.0.0/24 [1/0] via 192.168.0.9.*

S 10.16.0.0/16 is directly connected, Ethernet 0/1.

S 10.0.0.0/8 [1/0] via 192.168.0.2.

> Which two requirements are necessary before a router configured with a link-state routing protocol can build and send its link-state packets?. (Choose two).

The router has established its adjacencies.*

The router has constructed an SPF tree.

The router has determined the costs associated with its active links.*

The router has built its link-state database.

The routing table has been refreshed.

> Which route will a router use to forward an IPv4 packet after examining its routing table for the best match with the destination address?.

A level 2 supernet route. 

A level 1 ultimate route.*

A level 1 child route.

A level 1 parent route.

> Match the routing protocol to the corresponding category. (Not All Options Are Used).

> Fill in the blank. Do not abbreviate the answer.

The command #”version 2”# is used in RIP router configuration mode to enable the sending of subnet masks with the routing updates.

> In the context of routing protocols, what is a definition for time to convergence?.

A measure of protocol configuration complexity.

The capability to transport data, video, and voice over the same media.

The amount of time for the routing tables to achieve a consistent state after a topology change.*

The amount of time a network administrator needs to configure a routing protocol in a small- to medium- sized network.

> Fill in the blank. Do not abbreviate.

When configuring RIPng, the #“default-information originate”# command instructs the router to propagate a static default route.

> Which two statements are true regarding classless routing protocols?. (Choose two).

Allows for use of both 192.168.1.0/30 and 192.168.1.16/28 subnets in the same topology.*

Is supported by RIP version 1.

Sends subnet mask information in routing updates.*

Sends complete routing table update to all neighbors.

Reduces the amount of address space available in an organization.
