Under which of the following circumstances might you implement BGP on your company network and share routes with internet routers?
If the network is connected to the internet using multiple ISPs
You have a private network connected to the internet. Your routers will not share routing information about your private network with internet routers. Which of the following best describes the type of routing protocol you would use?
IPG
You have a router configured to share routing information using RIP. In addition, you have a single static route that identifies a default route for all other networks. The next hop router for the default has changed. You need to make the change with the least amount of effort possible. What should you do?
Manually reconfigure the default route to point to the new next hop router.
A router is connected to network 192.168.1.0/24 and network 192.168.2.0/24. the router is configured to use RIP and has learned of networks 192.168.3.0/24 and 192.168.4.0/24. The next hop router for network 192.168.3.0 has changed. You need to make the change with the least amount of effort possible. what should you do.
wait for convergence to take place.
you have a network configured to use the OSPF routing protocol. Which of the following describes the state when all OSPF routers have learned about all other routes in the network.
Convergence
When multiple routes to a destination exist, what is used to select the best possible route?
Metric
Which of the following routing protocols uses paths, rules, and policies instead of a metric for making routing decisions?
BGP
Which of the following are true for the IS-IS routing protocol? select two
Divides large networks into areas Supports IPv6 routing
One method of preventing routing loops is to not send information about a route back to the router from which the information came. What is this technique called?
Split horizon
What information does the next hop entry in a routing table identify?
The first router in the path to the destination network.
A router is connected to a network 192.169.1.0/24 and network 192.168.2.0/24. The router is configured to use RIP and has learned of networks 192.168.3.0/24 and 192.168.4.0/24. The router is also configured with a static route of 0.0.0.0 with a mask of 0.0.0.0. The router receives a packet addressed to the network 10.1.0.0/16. What will the router do with the packet.
Forward the packet to the next hop router specified by the route network 0.0.0.0
A router is connected to a network 192.168.1.0/24 and network 192.168.2.0/24. The router is configured to use RIP and has learned of networks 192.168.3.0/24 and 192.168.4.0/24. There is no default route on router. The router receives a packet addressed to network 10.1.0.0/16. What will the router do with the packet?
Drop the packet.
Which of the following is a characteristic of static routing when compared to dynamic routing?
All routers must be manually updated on the router.
Which two of the following tasks do routers perform?
Maintain information about paths through an internetwork. Route data based on logical network addresses.
You have been recently hired to mange a network for a small company. Prior to your arrival, the entire network was migrated from IPv4 to IPv6. Which strategy could you imply to help prevent these issues from occurring?
Use a /127 prefix on the backbone segment.
