- BR1, R3, R6, R7
- CR1, R3, R5, R6, R7
- DR1, R2, R5, R7

3Refer 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.)
- ARIP version 1 is running on this router and its RIP neighbor.
- BRIP version 2 is running on this router and its RIP neighbor.
- CThe command no auto-summary has been used on the RIP neighbor router.
- DRIP will advertise two networks to its neighbor.
- EThe metric to the network 172.16.0.0 is 120.
4Which two statements describe the OSPF routing protocol? (Choose two.)
- Aautomatically summarizes networks at the classful boundaries
- Bused primarily as an EGP
- Cuses Dijkstra’s algorithm to build the SPF tree
- Dhas an administrative distance of 100
- Ecalculates its metric using bandwidth
5What is the purpose of the passive-interface command?
- Aallows a router to send routing updates on an interface but not receive updates via that innterface
- Ballows interfaces to share IP addresses
- Callows a router to receive routing updates on an interface but not send updates via that interface
- Dallows an interface to remain up without receiving keepalives
- Eallows a routing protocol to forward updates out an interface that is missing its IP address
6In the context of routing protocols, what is a definition for time to convergence?
- Aa measure of protocol configuration complexity
- Bthe capability to transport data, video, and voice over the same media
- Cthe amount of time for the routing tables to achieve a consistent state after a topology change
- Dthe amount of time a network administrator needs to configure a routing protocol in a small- to medium-sized network
7Which two events will trigger the sending of a link-state packet by a link-state routing protocol? (Choose two.)
- Athe requirement to periodically flood link-state packets to all neighbors
- Ba change in the topology
- Cthe initial startup of the routing protocol process
- Dthe router update timer expiring
- Ea link to a neighbor router has become congested
8The command _________ is used in RIP router configuration mode to enable the sending of subnet masks with the routing updates.
- Aversion 2
- Bversion 3
9What two actions result from entering the network 192.168.1.0 command in RIP configuration mode on a router? (Choose two.)
- AThe RIP process is stopped and all existing RIP configurations are erased.
- BThe neighboring routers are sent a request for routing updates.
- CRouting updates are sent through all the interfaces belonging to 192.168.1.0
- DThe network address 192.168.1.0 is advertised to the neighbor routers
- EThe routing table is created in the RAM of the router.
10What two tasks do dynamic routing protocols perform? (Choose two.)
- Anetwork discovery
- Bupdate and maintain routing tables
- Cdiscover hosts
- Dpropagate host default gateways
- Eassign IP addressing
11Refer to the exhibit. Which interface will be the exit interface to forward a data packet with the destination IP address 172.16.0.66?
- ASerial0/0/0
- BSerial0/0/1
- CGigabitEthernet0/0
- DGigabitEthernet0/1
12Which route is the best match for a packet entering a router with a destination address of 10.16.0.2?
- AS 10.0.0.0/16 is directly connected, Ethernet 0/0
- BS 10.16.0.0/16 is directly connected, Ethernet 0/1
- CS 10.16.0.0/24 [1/0] via 192.168.0.9
- DS 10.0.0.0/8 [1/0] via 192.168.0.2
13When configuring RIPng, the default-information originate command instructs the router to propagate a static default route
- Adefault-information originate
- Bnot the right answer
14What is different between IPv6 routing table entries compared to IPv4 routing table entries?
- AIPv6 does not use static routes to populate the routing table as used in IPv4.
- BThe selection of IPv6 routes is based on the shortest matching prefix, unlike IPv4 route selection which is based on the longest matching prefix.
- CIPv6 routing tables include local route entries which IPv4 routing tables do not.
- DBy design IPv6 is classless so all routes are effectively level 1 ultimate routes.
15Which two requirements are necessary before a router configured with a link-state routing protocol can build and send its link-state packets? (Choose two.)
- AThe router has constructed an SPF tree.
- BThe router has built its link-state database.
- CThe router has established its adjacencies.
- DThe router has determined the costs associated with its active links.
- EThe routing table has been refreshed.
16Which dynamic routing protocol was developed as an exterior gateway protocol to interconnect different Internet providers?
- AOSPF
- BEIGRP
- CRIP
- DBGP
17Which two requirements are used to determine if a route can be considered as an ultimate route in a router’s routing table? (Choose two.)
- Acontain subnets
- Bcontain a next-hop IP address
- Ccontain an exit interface
- Dbe a default route
- Ebe a classful network entry
18A destination route in the routing table is indicated with a code D. Which kind of route entry is this?
- Aa route dynamically learned through the EIGRP routing protocol
- Ba network directly connected to a router interface
