24. How does the service password-encryption command enhance password security on Cisco routers and switches? It encrypts passwords as they are sent across the network. 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 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.

10. What is done to an IP packet before it is transmitted over the physical medium? It is tagged with information guaranteeing reliable delivery It is segmented into smaller individual pieces It is encapsulated into a TCP segment It is encapsulated in a Layer 2 frame

It is encapsulated in a Layer 2 frame

It provides connections through interconnected global networks.

21. A network administrator needs to keep the user ID, password, and session contents private when establishing remote CLI connectivity with a switch to manage it. Which access method should be chosen? Telnet Console AUX SSH

SSH

2. What is the purpose of the SVI on a Cisco switch? The SVI provides a physical interface for remote access to the switch. The SVI provides a faster method for switching traffic between ports on the switch. The SVI adds Layer 4 connectivity between VLANs. The SVI provides a virtual interface for remote access to the switch.

The SVI provides a virtual interface for remote access to the switch.

30. Which statement is true about the TCP/IP and OSI models? The TCP/IP transport layer and OSI Layer 4 provide similar services and functions. The TCP/IP network access layer has similar functions to the OSI network layer. The OSI Layer 7 and the TCP/IP application layer provide identical functions. The first three OSI layers describe general services that are also provided by the TCP/IP internet layer.

The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.

29. Which statement is correct about network protocols? Network protocols define the type of hardware that is used and how it is mounted in racks. They define how messages are exchanged between the source and the destination. They all function in the network access layer of TCP/IP. They are only required for exchange of messages between devices on remote networks.

They define how messages are exchanged between the source and the destination.

7. A network administrator enters the service password-encryption command into the configuration mode of a router. What does this command accomplish? This command encrypts passwords as they are transmitted across serial WAN links. This command prevents someone from viewing the running configuration passwords. This command enables a strong encryption algorithm for the enable secret password command. This command automatically encrypts passwords in configuration files that are currently stored in NVRAM.

This command prevents someone from viewing the running configuration passwords.
