| Question | Answer |
|---|---|
| What types of standards are developed by the Electronics Industries Alliance (EIA)? | electric wiring and connectors |
| Which services are provided by the internet layer of the TCP/IP protocol suite? (Choose three.) | Messaging Internet Protocol Routing Protocols |
| BGP and OSPF are examples of which type of protocol? | Routing |
| This standards organization is concerned with the Request for Comments (RFC) documents that specify new protocols and update existing ones. | Internet Engineering Task Force (IETF) |
| Which of the following are protocols that provide feedback from the destination host to the source host regarding errors in packet delivery? (Choose two.) | ICMPv4 ICMPv6 |
| This standards organization is responsible for IP address allocation and domain name management. Group of answer choices Internet Engineering Task Force (IETF) | Internet Assigned Numbers Authority (IANA) |
| Which delivery method is used to transmit information to a single device? | Unicast |
| This protocol is responsible for guaranteeing the reliable delivery of information. | TCP |
| Which two protocols belong in the TCP/IP model application layer? | DHCP DNS |
| This is not predefined; it is a value or variable defined by the user | argument |
| What privileged EXEC mode command will you use to show the current configurations that you made? | show running-config |
| True or False? Mobile devices do not require IP addresses to communicate on the Internet. | False |
| To move from user EXEC mode to privileged EXEC mode, What command should you use? | enable |
| Which access method would be most appropriate if your manager gave you a special cable and told you to use it to configure the switch? | Console |
| Which is the command to configure a banner to be displayed when connecting to a switch? | banner motd # Keep out # |
| Which IOS mode are you in if the Switch(config)# prompt is displayed? | Global Configuration Mode |
| How is an IPv4 address represented? | four decimal numbers between 0 and 255 separated by periods |
| To save time, IOS commands may be partially entered and then completed by typing which key or key combination? | Tab |
| This is the saved configuration file that is stored in NVRAM. It contains all the commands that will be used by the device upon startup or reboot. | startup-config |
| Which delivery method is used to transmit information to all devices? | Broadcast |
| True or false. Standards organizations are usually vendor-neutral. | True |
| Which delivery method is used to transmit information to one or more end devices, but not all devices on the network? | Multicast |
| True or False? Data Link addresses are physical so they never change in the data link frame from source to destination. | False |
| True or false? Frames exchanged between devices in different IP networks must be forwarded to a default gateway. | True |
| Which protocol stack layer encapsulates data into frames? | data link |
| UDP and TCP belong to which layer of the TCP/IP protocol? | transport |
| Which protocol operates at the network access layer of the TCP/IP model? | Ethernet |
| Which of the following statements are true regarding network layer and data link layer addresses? (Choose three.) | Network layer addresses are logical and data link addresses are expressed as 12 hexadecimal digits. Network layer addresses are either 32 or 128 bits in length. Data link layer addresses are physical and network layer addresses are logical. |
| What is used to determine the network portion of an IPv4 address? | subnet mask |
| Why would a technician enter the command copy startup-config running-config? | to copy an existing configuration into RAM |
| How is SSH different from Telnet? | SSH provides security to remote sessions by encrypting messages and using user authentication. Telnet is considered insecure and sends messages in plaintext. |
| What is the correct format for IPv4 address? | 192.168.0.1 192.168.0.5 |
| Which interface allows remote management of a Layer 2 switch? | the switch virtual interface |
| Which access method would be most appropriate if you were in the equipment room with a new switch that needs to be configured? | Console |
| Which command encrypts all plaintext passwords access on a switch? | service password-encryption |
| What is the function of the kernel of an operating system? | The kernel provisions hardware resources to meet software requirements. |
| What is the order of the two addresses in the data link frame? | destination MAC, source MAC |
| Which three are components of message timing? (Choose three.) | Response Timeout Access Method Flow control |
| A device receives a data link frame with data and processes and removes the Ethernet information. What information would be the next to be processed by the receiving device? | IP at the Internet layer |
| What is the process of converting information into the proper form for transmission? | Encoding |
| The physical part of a computer including underlying electronics. | Hardware |
| What command is used to save changes made to the running configuration to the startup configuration file. | copy running-config startup-config |
| Which device acts as a gateway to allow hosts to send traffic to remote IP networks? | local router |
| What is the command to assign the name "Sw-Floor-2" to a switch? | hostname Sw-Floor-2 |
| Which procedure is used to access a Cisco 2960 switch when performing an initial configuration in a secure environment? | Use the console port to locally access the switch from a serial or USB interface of the PC. |
| What command will prevent all unencrypted passwords from displaying in plain text in a configuration file? | (config)# service password-encryption. |
| An administrator has just changed the IP address of an interface on an IOS device. What else must be done in order to apply those changes to the device? | Nothing must be done. Changes to the configuration on an IOS device take effect as soon as the command is typed correctly and the Enter key has been pressed. |
| What is the command to assign the name "Switch-1-Floor" to a switch? | hostname Switch-1-Floor |
| Communicates between the hardware and software of a computer and manages how hardware resources are used to meet software requirements. | Kernel |
