Which parameter or parameters are used to calculate OSPF cost in Cisco routers?

Why do large OSPF networks use a hierarchical design? (Choose three.)

Which command encrypts all plaintext passwords?

Which two are advantages of static routing when compared to dynamic routing? (Choose two.)

A network administrator needs to allow only one Telnet connection to a router. For anyone viewing
the configuration and issuing the show run command, the password for Telnet access should be
encrypted. Which set of commands will accomplish this task?

Refer to the exhibit.

The speed of all serial links is E1 and the speed of all Ethernet links is 100 Mb/s. A static route will
be established on the Manchester router to direct traffic toward the Internet over the most direct
path available. What configuration on the Manchester router will establish a route toward the
Internet for traffic that originates from workstations on the Manchester LAN?

Refer to the exhibit.

The network administrator must establish a route by which London workstations can forward traffic
to the Manchester workstations. What is the simplest way to accomplish this?

Refer to the exhibit.

The network administrator requires easy configuration options and minimal routing protocol traffic.
What two options provide adequate routing table information for traffic that passes between the
two routers and satisfy the requests of the network administrator? (Choose two.)

What is the effect of using the service password-encryption command?

Refer to the exhibit.

What is the effect of the configuration that is shown?
