212. Routers

What routing protocols that manage traffic within an autonomous system?

Interior Gateway Protocols (IGP).

Routers operate at what layer of the OSI Model?

Layer 3, Routers operate at the Network layer of the OSI Model.

Name three metrics that routers use to determine the best route

Path length, reliability, routing delay, bandwidth, load, and communication cost.

Name two methods for directing data on the network.

Static or dynamic

What is static routing?

Static routing is a technique in which a network administrator programs a router to use specific paths between nodes.

Dynamic routing automatically calculates the best path between how many nodes? a. 2. b. 3. c. 4. d. 5.

a. 2.

What is dynamic routing?

automatically calculates the best path between two nodes and compiles this info in a routing table.

Which of these is an example of an Exterior Gateway Protocol? a. Open Shortest Path First. b. Border Gateway Protocol. c. Routing Information Protocol. d. Enhanced Gateway Routing Protocol.

b. Border Gateway Protocol

What layer of the open system interconnection model do routers operate? a. Layer 2. b. Layer 3. c. Layer 4. d. Layer 5.

b. Layer 3.

What do routing algorithms initialize and maintain to aid the process of path determination? a. Routing times. b. Routing tables. c. Longest routes. d. Shortest routes.

b. Routing tables.

What does a typical router contain?

internal processor, an operating system, memory, input and output jacks for different types of network connectors and, usually, a management console interface.
