Q

What are two advantages of static routing over dynamic routing? (Choose two.)

Static routing is more secure because it does not advertise over the network.

Static routing scales well with expanding networks.

Static routing requires very little knowledge of the network for correct implementation.

Static routing uses fewer router resources than dynamic routing.

Static routing is relatively easy to configure for large networks.

A

Q

What is a characteristic of a static route that matches all packets?

It backs up a route already discovered by a dynamic routing protocol.

It uses a single network address to send multiple static routes to one destination address.

It identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route.

It is configured with a higher administrative distance than the original dynamic routing protocol has.

A

It identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route.

Q

Why would a floating static route be configured with an administrative distance that is higher than the administrative distance of a dynamic routing protocol that is running on the same router?

to be used as a backup route

to load-balance the traffic

to act as a gateway of last resort

to be the priority route in the routing table

Q

What happens to a static route entry in a routing table when the outgoing interface associated with that route goes into the down state?

The static route is removed from the routing table.

The router polls neighbors for a replacement route.

The static route remains in the table because it was defined as static.

The router automatically redirects the static route to use another interface.

A

The static route is removed from the routing table.
