Wide Area Network

When a router receives multiple possible routes for the same network connection from three different routing protocols, what information will the router use to choose the route it adds to its routing table?

• autonomous system

• convergence time

• overhead

• administrative distance

With which network type does a single organization most likely own all the equipment?

• WAN

• SD-WAN

• CAN

• MAN

What technique will ensure a message arrives at it's destination even if a router along the path loses power?

• backup

• best path

• fallover

• multiplexing

Which of the following is NOT an optimal application of a MAN?

• long-haul connection across states

• high-speed disaster recovery site

• interconnection between corporate data center and ISP

• real-time transaction backup

Which device determines the best path for a message traversing the internet?

• switch

• fiber cable

• router

• multiplexor

Which algorithm is often used to help calculate the least-cost path on a network?

• Lempel-Ziv

• DWDM

• Dijkstra

• MU-MIMO

Which routing protocol requires that routers transmit their routing tables every 30 seconds?

• EIGRP

• OSPF

• IS-IS

• RIP

Which routing protocol has the lastest convergence time?

• EIGRP

• OSPF

• RIPv2

• IS-IS

How does OSPF advertise its routing information?

• It listens for update requests from each of its neighbors

• It floods other routers with link-state packets when something changes

• It measures the delay or cost to each neighboring router

• It floods other routers with its entire routing tables every 30 seconds

As you're designing your network across multiple, private WAN connections, you realize you need to choose a secure routing protocol for your AS. Which of the following would NOT be a resonable choice to consider?

• BGP

• IS-IS

• EIGRP

• RIPv2
