What are three characteristics of an SVI? (Choose three.) It is associated with VLAN1 by default. It is a special interface that allows connectivity by different types of media. It provides a means to remotely manage a switch. It is not associated with any physical interface on a switch. It is required to allow connectivity by any device at any location. It is designed as a security protocol to protect switch ports.

What is an advantage of network devices using open standard protocols? Internet access can be controlled by a single ISP in each market. Network communications is confined to data transfers between devices from the same vendor. A client host and a server running different operating systems can successfully exchange data. Competition and innovation are limited to specific types of products.

A client host and a server running different operating systems can successfully exchange data.

Which statement is correct about network protocols? They all function in the network access layer of TCP/IP. Network protocols define the type of hardware that is used and how it is mounted in racks. 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.

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

2,5,6

What are two characteristics of RAM on a Cisco device? (Choose two.) RAM is a component in Cisco switches but not in Cisco routers. The configuration that is actively running on the device is stored in RAM. The contents of RAM are lost during a power cycle. RAM provides nonvolatile storage. RAM is able to store multiple versions of IOS and configuration files.

From the perspective of the client, what is the correct order of the protocol stack that is used to decode the received transmission? HTTP, TCP, IP, Ethernet Ethernet, TCP, IP, HTTP HTTP, Ethernet, IP, TCP Ethernet, IP, TCP, HTTP

Match the description to the organization [Not all options are used.]

ISOC -> The organization promotes the open development, evolution, and use of the internet throughout the worldISO -> This organization is the largest developer of international standars in the world for a wide variety of products and services. It is know for its Open System Interconnection (OSI) reference model.IANA -> This organization is responsible for overseeing and managing IP address allocation, domain name management, and protocol identifiers

How is SSH different from Telnet? SSH must be configured over an active network connection, whereas Telnet is used to connect to a device from a console connection. SSH provides security to remote sessions by encrypting messages and using user authentication. Telnet is considered insecure and sends messages in plaintext. SSH makes connections over the network, whereas Telnet is for out-of-band access. SSH requires the use of the PuTTY terminal emulation program. Tera Term must be used to connect to devices through the use of Telnet. Navigation Bar

A technician configures a switch with these commands: SwitchA(config)# interface vlan 1 SwitchA(config-if)# ip address 192.168.1.1 255.255.255.0 SwitchA(config-if)# no shutdown What is the technician configuring? SVI physical switchport access password encryption Telnet access

SVI

Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network? Packets are sent from the network access layer to the transport layer. Frames are sent from the network access layer to the internet layer. Segments are sent from the transport layer to the internet layer. Data is sent from the internet layer to the network access layer.

Segments are sent from the transport layer to the internet layer.

Switch1?> config t invalid input detected An administrator is trying to configure the switch but receives the error message that is displayed in the exhibit. What is the problem? The entire command, configure terminal , must be used. The administrator must connect via the console port to access global configuration mode. The administrator must first enter privileged EXEC mode before issuing the command. The administrator is already in global configuration mode.

The administrator must first enter privileged EXEC mode before issuing the command.

For the TCP/IP protocol suite, what is the correct order of events when a Telnet message is being prepared to be sent over the network?

The telnet-formatted data is provided to the next alyer the TCP header is added the ip header is added the Ethernet header is added

What is a characteristic of multicast messages? They are sent to all hosts on a network. They must be acknowledged. They are sent to a select group of hosts. They are sent to a single destination.

They are sent to a select group of hosts.

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

This command prevents someone from viewing the running configuration passwords.
