1The command =?= is used in RIP router configuration mode to enable the sending of subnet masks with the routing updates.
- Aversion 1
- Bversion 2
2Which route will a router use to forward an IPv4 packet after examining its routing table for the best match with the destination address?
- Aa level 2 supernet route
- Ba level 1 child route
- Ca level 1 parent route
- Da level 1 ultimate route
3What two tasks do dynamic routing protocols perform? (Choose two.)
- Aassign IP addressing
- Bnetwork discovery
- Cupdate and maintain routing tables
- Ddiscover hosts
- Epropagate host default gateways
4What is the purpose of the passive-interface command?
- Aallows an interface to remain up without receiving keepalives
- Ballows a routing protocol to forward updates out an interface that is missing its IP address
- Callows interfaces to share IP addresses
- Dallows a router to send routing updates on an interface but not receive updates via that innterface
- Eallows a router to receive routing updates on an interface but not send updates via that interface
5Which two statements are true regarding classless routing protocols? (Choose two.)
- Aallows for use of both 192.168.1.0/30 and 192.168.1.16/28 subnets in the same topology
- Breduces the amount of address space available in an organization
- Cis supported by RIP version 1
- Dsends subnet mask information in routing updates
- Esends complete routing table update to all neighbors
6Which two statements describe the OSPF routing protocol? (Choose two.)
- Aautomatically summarizes networks at the classful boundaries
- Bhas an administrative distance of 100
- Cuses Dijkstra's algorithm to build the SPF tree
- Dcalculates its metric using bandwidth
- Eused primarily as an EGP
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
- Bthe initial startup of the routing protocol process
- Ca link to a neighbor router has become congested
- Dthe router update timer expiring
- Ea change in the topology
8Which dynamic routing protocol was developed as an exterior gateway protocol to interconnect different Internet providers?
- ABGP
- BOSPF
- CEIGRP
- DRIP
9In the context of routing protocols, what is a definition for time to convergence?
- Athe amount of time a network administrator needs to configure a routing protocol in a small- to medium-sized network
- Ba measure of protocol configuration complexity
- Cthe amount of time for the routing tables to achieve a consistent state after a topology change
- Dthe capability to transport data, video, and voice over the same media
10What is different between IPv6 routing table entries compared to IPv4 routing table entries?
- ABy design IPv6 is classless so all routes are effectively level 1 ultimate routes.
- 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.
- DIPv6 does not use static routes to populate the routing table as used in IPv4.
11Which 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 an exit interface
- Cbe a classful network entry
- Dcontain a next-hop IP address
- Ebe a default route
12Refer 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
13Which 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 routing table has been refreshed.
- CThe router has built its link-state database.
- DThe router has determined the costs associated with its active links.
- EThe router has established its adjacencies.
14Which 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 10.16.0.0/24 [1/0] via 192.168.0.9
- CS 10.16.0.0/16 is directly connected, Ethernet 0/1
- DS 10.0.0.0/8 [1/0] via 192.168.0.2
15Refer 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?
- AR1, R3, R6, R7
- BR1, R2, R5, R7
- CR1, R3, R5, R7
- DR1, R4, R6, R7
- ER1, R3, R5, R6, R7
16When configuring RIPng, the =?= command instructs the router to propagate a static default route.
- Adefault-information originate
- Bdefault-information
- Coriginate
17A 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 route used as the default gateway
- Ca network directly connected to a router interface
- Da static route
18Refer 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.)
