Chapter 6 - static routes
Flashcards do conjunto (10)
- 1What devices are responsible for the transfer of packets from one network to the next?Routers
- 2Routers learn about remote networks in one of two ways. List and explain both.a. _____Manually___ – Remote networks are manually entered into the route table using static routes
b. __Dynamically____ – Remote routes are automatically learned using a dynamic routing protocol - 3Explain the advantages static routing provides over dynamic routing.a. Static routes are not advertised over the network, resulting in better security
b. Static routes use less bandwidth than dynamic routing protocols, no CPU cycles are used to calculate and communicate routes
c. The path a static route uses to send data is known - 4Explain the disadvantages of static routing.a. Initial configuration and maintenance is time-consuming.
b. Configuration is error-prone, especially in large networks.
c. Administrator intervention is required to maintain changing route information
d. Does no scale well with growing networks; maintenance becomes cumbersome.
e. Requires complete knowledge of the whole network for proper implementation - 5Do most networks use dynamic routing protocols, static routes, or a combination of both?combination
- 6The administrative distance (AD) of a static route is 1. Which type of route will take precedence, a static route or dynamically learned routes?static
- 7What are the three primary uses for static routing?a. Providing ease of routing table maintenance in smaller networks that are not expected to grow significantly
b. Routing to and from stub networks. A stub network is a network accessed by a single route, and the router has only one neighbor.
c. Using a single default route to represent a path to any network that does not have a more specific match with another route in the routing table. Default routes are used to send traffic to any destination beyond the next upstream router - 8Static routes can be used to do what?a. connect to a specific network
b. connect a stub router
c. summarize routing table entries
d. Create a backup route
They can also be used to:
e. Reduce the number of routes advertised by summarizing several contiguous networks as one static route
f. Create a backup route in case a primary route link fails - 9What does a default route identify?A default route identifies the gateway IP address to which the router sends all IP packets that it does not have a learned or static route.
- 10Explain when default static routes are used:a. When no other routes in the routing table match the packet destination IP address. In other words, when a more specific match does not exist.
b. When a router has only one other router to which it is connected. This condition is known as a stub router
