What service is provided by BOOTP?

• Uses encryption to secure the exchange of text, graphic images, sound, and video on the web.

• Allows for data transfers between a client and a file server.

• Legacy application that enables a diskless workstation to discover its own IP address and find a BOOTP server on the network.

• A basic set of rules for exchanging text, graphic images, sound, video, and other multimedia files on the web.

What characteristic describes adware?

• a network device that filters access and traffic coming into a network

• software that is installed on a user device and collects information about the user

• the use of stolen credentials to access private data

• an attack that slows or crashes a device or network service

How does the service password-encryption command enhance password security on Cisco routers and switches?

• It requires encrypted passwords to be used when connecting remotely to a router or switch with Telnet.

• It encrypts passwords that are stored in router or switch configuration files.

• It requires that a user type encrypted passwords to gain console access to a router or switch.

• It encrypts passwords as they are sent across the network.
