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

• 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.
• The network address 192.168.1.0 is advertised to the neighbor routers.
• The routing table is created in the RAM of the router.

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

• allows a router to send routing updates on an interface but not receive updates via that interface

• allows a router to receive routing updates on an interface but not send updates via that interface
• allows a routing protocol to forward updates out an interface that is missing its IP address
• allows an interface to remain up without receiving keep alive

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

• has an administrative distance of 100
• uses Dijkstra’s algorithm to build the SPF tree
• used primarily as an EGP
• automatically summarizes networks at the classful boundaries
• calculates its metric using bandwidth

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

• update and maintain routing tables
• network discovery
• assign IP addressing
• discover hosts
• propagate host default gateways

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

• sends complete routing table update to all neighbors
• allows for use of both 192.168.1.0/30 and 192.168.1.16/28 subnets in the same topology
• reduces the amount of address space available in an organization
• sends subnet mask information in routing updates
• is supported by RIP version 1

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.)

• 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.
• RIP version 2 is running on this router and its RIP neighbor.
• RIP version 1 is running on this router and its RIP neighbor.

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

• EIGRP
• RIP
• BGP
• OSPF

11.Fill in the blank. Do not abbreviate.
When configuring RIPng, the default-information originatecommand instructs the router to propagate a static default route.

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

• 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
• a measure of protocol configuration complexity

• R1, R3, R5, R7
• R1, R4, R6, R7
• R1, R3, R5, R6, R7
• R1, R2, R5, R7
• R1, R3, R6, R7

14.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 route dynamically learned through the EIGRP routing protocol
• a static route
• a network directly connected to a router interface

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?

• Serial0/0/1
• GigabitEthernet0/1
• Serial0/0/0
• GigabitEthernet0/0

16.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.

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

• a link to a neighbor router has become congested
• the initial startup of the routing protocol process
• the requirement to periodically flood link-state packets to all neighbors
• the router update timer expiring
• a change in the topology

18.Match the features of link-state routing protocols to their advantages and disadvantages. (Not all options are used.)

19.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 built its link-state database.
• The router has established its adjacencies.
• The router has constructed an SPF tree.
• The router has determined the costs associated with its active links.

• be a classful network entry
• contain a next-hop IP address

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

• By design IPv6 is classless so all routes are effectively level 1 ultimate routes.
• IPv6 does not use static routes to populate the routing table as used in IPv4.
• IPv6 routing tables include local route entries which IPv4 routing tables do not.
• The selection of IPv6 routes is based on the shortest matching prefix, unlike IPv4 route
• selection which is based on the longest matching prefix.

22.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 1 parent route
• a level 2 supernet route
• a level 1 child route
• a level 1 ultimate route
