What is an advantage of OSPF compared to RIP?

A. Fast convergence

What command, or set of commands, would be used to determine if the following configuration on router HQ works as designed? ip route 0 . 0 . 0 . 0 0 . 0 . 0 . 0 serial 0 / 0 / 0 10 ip route 0 . 0 . 0 . 0 0 . 0 . 0 . 0 serial 0 / 1 / 0

A. HQ(config)# interface serial 0 / 1 / 0 H Q ( c o n f i g - i f ) # shutdown H Q ( c o n f i g - i f ) # end HQ# show ip route

Which two conditions must exist in order to summarize IPv6 routes into a single static IPv6 route? (Choose two.) A. The destination networks are contiguous and can be summarized into a single network address. B. The multiple static routes all use different exit-interface or next-hop IPv6 address. C. The destination networks are not contiguous. D. The multiple static routes all use the same exit-interface or next-hop IPv6 address. E. The administrative distance is greater than the administrative distance of another static route or dynamic routes.

A. The destination networks are contiguous and can be summarized into a single network address. D. The multiple static routes all use the same exit-interface or next-hop IPv6 address.

What are two characteristics of link-state protocols compared to distance vector protocols? (Choose two.) A. They require a lot of hardware resources. B. They know of the network topology from the perspective of their neighbors. C. They compute their own knowledge of the network topology. D. They use hop counts to compute the network topology. E. They flood the routing table periodically.

A. They require a lot of hardware resources. C. They compute their own knowledge of the network topology.

What are two functions of dynamic routing protocols? (Choose two.) A. To maintain routing tables B. To assure low router overheard C. To avoid exposing network information D. To discover the network E. To choose the path that is specified by the administrator

A. To maintain routing tables D. To discover the network

Which option shows a correctly configured IPv4 default static route?

A. ip route 0.0.0.0 0.0.0.0 S0/0/0

Which is a valid summary route for networks 192.168.8.0/22, 192.168.12.0/22, and 192.168.16.0/22?

B. 192.168.0.0/19

Which subnet mask would be used for a network that has a maximum of 300 devices?

B. 255.255.254.0

Which of the following are three characteristics of a static route? (Choose three.) A. Reduces the memory and processing burdens on a router. B. Ensures that there is always a path available. C. Used to dynamically find the best path to a destination network. D. Used for routers that connect to stub networks. E. Used for networks with a single route to a destination network. F. Reduces configuration time.

B. Ensures that there is always a path available. D. Used for routers that connect to stub networks. E. Used for networks with a single route to a destination network.

Which classless routing protocol supports VLSM and CIDR, supports manual route summarization, and uses the multicast address 224.0.0.9?

B. RIPv2

A network administrator has examined the routing table of a router and noted that the entry for the destination network 172.16.4.0/24 begins with the letter D. What does this letter signify?

B. The route source was learned dynamically.

Which algorithm is used by the OSPF routing process to construct the SPF tree on a router?

C. Dijkstra's algorithm

What type of static route is created when the next-hop IP address and exit interface are specified?

C. Fully specified static route

Which statement is true concerning configuring static routes using next-hop addresses?

C. Routers configured with the static route using a next-hop address must either have the exit interface listed in the route or have another route with the network of the next hop and an associated exit interface.

Which factor directly affects the time to convergence?

C. Size of the network

A network administrator enters the following command into Routerl: ip route 192.168.0. 0 255.255.255.0 S 0 / 1 / 0 . Routerl then receives a packet that is destined for 192.168.0.22/24. After finding the recently configured static route in the routing table, what does Router1 do next to process the packet?

D. Encapsulates the packet into a frame for the WAN link and forwards the packet out the S 0 / 1 / 0 interface.

What is the difference between interior and exterior routing protocols?

D. Interior routing protocols are used to communicate within a single autonomous system. Exterior routing protocols are used to communicate between multiple autonomous systems.

What is the purpose of classifying Cisco IP routing table entries as ultimate route, level 1 route, level 1 parent route, and level 2 child routes?

D. To explain the operation of the hierarchical structure of the routing table

Why would a summarized static route be configured on a router?

D. To reduce the size of the routing table

Which classless routing protocol supports VLSM and CIDR, bounded and triggered updates, and uses the multicast address of 224.0.0.10?

EIGRP
