1. During a routine inspection, a technician discovered that software that was installed on a computer was secretly collecting data about websites that were visited by users of the computer. Which type of threat is affecting this computer?DoS attack 2. Which term refers to a network that provides secure access to the corporate offices by suppliers, customers and collaborators?Internet 3. A large corporation has modified its network to allow users to access network resources from their personal laptops and smart phones. Which networking trend does this describe?cloud computing 4. What is an ISP?It is a standards body that develops cabling and wiring standards for networking. 5. Match the requirements of a reliable network with the supporting network architecture. (Not all options are used.)CCNA 1 v7 Modules 1 – 3 Exam Answers p5 6. An employee at a branch office is creating a quote for a customer. In order to do this, the employee needs to access confidential pricing information from internal servers at the Head Office. What type of network would the employee access?an intranet* 7. Which statement describes the use of powerline networking technology?New “smart” electrical cabling is used to extend an existing home LAN. 8. A networking technician is working on the wireless network at a medical clinic. The technician accidentally sets up the wireless network so that patients can see the medical records data of other patients. Which of the four network characteristics has been violated in this situation?fault tolerance Explanation: Network security includes protecting the confidentiality of data that is on the network. In this case, because confidential data has been made available to unauthorized users, the security characteristic of the network has failed. 9. Match each characteristic to its corresponding Internet connectivity type. (Not all options are used.)
Explanation: DSL is an always-on, high bandwidth connection that runs over telephone lines. Cable uses the same coaxial cable that carries television signals into the home to provide Internet access. Dialup telephone is much slower than either DSL or cable, but is the least expensive option for home users because it can use any telephone line and a simple modem. Satellite requires a clear line of sight and is affected by trees and other obstructions. None of these typical home options use dedicated leased lines such as T1/E1 and T3/E3. 10. What two criteria are used to help select a network medium from various network media? (Choose two.)the types of data that need to be prioritized 11. What type of network traffic requires QoS?email 12. A user is implementing security on a small office network. Which two actions would provide the minimum security requirements for this network? (Choose two.)implementing a firewall* Explanation: Technically complex security measures such as intrusion prevention and intrusion prevention systems are usually associated with business networks rather than home networks. Installing antivirus software, antimalware software, and implementing a firewall will usually be the minimum requirements for home networks. Installing a home wireless network will not improve network security, and will require further security actions to be taken. 13. Passwords can be used to restrict access to all or parts of the Cisco IOS. Select the modes and interfaces that can be protected with passwords. (Choose three.)VTY interface 14. Which interface allows remote management of a Layer 2 switch?the AUX interface Explanation: In a Layer 2 switch, there is a switch virtual interface (SVI) that provides a means for remotely managing the device. 15. What function does pressing the Tab key have when entering a command in IOS?It aborts the current command and returns to configuration mode. Explanation: Pressing the Tab key after a command has been partially typed will cause the IOS to complete the rest of the command. 16. While trying to solve a network issue, a technician made multiple changes to the current router configuration file. The changes did not solve the problem and were not saved. What action can the technician take to discard the changes and work with the file in NVRAM?Issue the reload command without saving the running configuration.* Explanation: The technician does not want to make any mistakes trying to remove all the changes that were done to the running configuration file. The solution is to reboot the router without saving the running configuration. The copy startup-config running-config command does not overwrite the running configuration file with the configuration file stored in NVRAM, but rather it just has an additive effect. 17. An administrator uses the Ctrl-Shift-6 key combination on a switch after issuing the ping command. What is the purpose of using these keystrokes?to restart the ping process 18. Refer to the exhibit.A network administrator is configuring access control to switch SW1. If the administrator uses a console connection to connect to the switch, which password is needed to access user EXEC mode?letmein Explanation: Telnet accesses a network device through the virtual interface configured with the line VTY command. The password configured under this is required to access the user EXEC mode. The password configured under the line console 0 command is required to gain entry through the console port, and the enable and enable secret passwords are used to allow entry into the privileged EXEC mode. 19. 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?Telnet access Explanation: For a switch to have an IP address, a switch virtual interface must be configured. This allows the switch to be managed remotely over the network. 20. Which command or key combination allows a user to return to the previous level in the command hierarchy?end Explanation: End and CTRL-Z return the user to the privileged EXEC mode. Ctrl-C ends a command in process. The exit command returns the user to the previous level. 21. What are two characteristics of RAM on a Cisco device? (Choose two.)RAM provides nonvolatile storage. 22. Which two host names follow the guidelines for naming conventions on Cisco IOS devices? (Choose two.)Branch2! Explanation: Some guidelines for naming conventions are that names should: 23. How is SSH different from Telnet?SSH makes connections over the network, whereas Telnet is for out-of-band access. Explanation: SSH is the preferred protocol for connecting to a device operating system over the network because it is much more secure than Telnet. Both SSH and Telnet are used to connect to devices over the network, and so are both used in-band. PuTTY and Terra Term can be used to make both SSH and Telnet connections. 24. An administrator is configuring a switch console port with a password. In what order will the administrator travel through the IOS modes of operation in order to reach the mode in which the configuration commands will be entered? (Not all options are used.)
Explanation: The configuration mode that the administrator first encounters is user EXEC mode. After the enable command is entered, the next mode is privileged EXEC mode. From there, the configure terminal command is entered to move to global configuration mode. Finally, the administrator enters the line console 0 command to enter the mode in which the configuration will be entered. 25. What are three characteristics of an SVI? (Choose three.)It is designed as a security protocol to protect switch ports. Explanation: Switches have one or more switch virtual interfaces (SVIs). SVIs are created in software since there is no physical hardware associated with them. Virtual interfaces provide a means to remotely manage a switch over a network that is using IP. Each switch comes with one SVI appearing in the default configuration “out-of-the-box.” The default SVI interface is VLAN1. 26. What command is used to verify the condition of the switch interfaces, including the status of the interfaces and a configured IP address?ipconfig Explanation: The show ip interface brief command is used to display a brief synopsis of the condition of the device interfaces. The ipconfig command is used to verify TCP/IP properties on a host. The ping command is used to verify Layer 3 connectivity. The traceroute command is used to trace the network path from source to destination. 27. Match the description with the associated IOS mode. (Not all options are used.)28. Match the definitions to their respective CLI hot keys and shortcuts. (Not all options are used.)29. In the show running-config command, which part of the syntax is represented by running-config?the command Explanation: The first part of the syntax, show, is the command, and the second part of the syntax, running-config, is the keyword. The keyword specifies what should be displayed as the output of the show command. 30. After making configuration changes on a Cisco switch, a network administrator issues a copy running-config startup-config command. What is the result of issuing this command?The new configuration will be stored in flash memory. 31. What command will prevent all unencrypted passwords from displaying in plain text in a configuration file?(config)# enable password secret 32. 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. Explanation: The startup-config and running-config files display most passwords in plaintext. Use the service password-encryption global config command to encrypt all plaintext passwords in these files. 33. What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?encapsulation Explanation: In order for two computers to be able to communicate effectively, there must be a mechanism that allows both the source and destination to set the timing of the transmission and receipt of data. Flow control allows for this by ensuring that data is not sent too fast for it to be received properly. 34. Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?Data is sent from the internet layer to the network access layer. Explanation: When the data is traveling from the PC to the network, the transport layer sends segments to the internet layer. The internet layer sends packets to the network access layer, which creates frames and then converts the frames to bits. The bits are released to the network media. 35. What three application layer protocols are part of the TCP/IP protocol suite? (Choose three.)ARP Explanation: DNS, DHCP, and FTP are all application layer protocols in the TCP/IP protocol suite. ARP and PPP are network access layer protocols, and NAT is an internet layer protocol in the TCP/IP protocol suite. 36. Match the description to the organization. (Not all options are used.)37. Which name is assigned to the transport layer PDU?bits Explanation: Application data is passed down the protocol stack on its way to be transmitted across the network media. During the process, various protocols add information to it at each level. At each stage of the process, a PDU (protocol data unit) has a different name to reflect its new functions. The PDUs are named according to the protocols of the TCP/IP suite: 38. When IPv4 addressing is manually configured on a web server, which property of the IPv4 configuration identifies the network and host portion for an IPv4 address?DNS server address Explanation: There are several components that need to be entered when configuring IPv4 for an end device: 39. What process involves placing one PDU inside of another PDU?Encapsulation* Explanation: When a message is placed inside of another message, this is known as encapsulation. On networks, encapsulation takes place when one protocol data unit is carried inside of the data field of the next lower protocol data unit. 40. What layer is responsible for routing messages through an internetwork in the TCP/IP model?Internet* Explanation: The TCP/IP model consists of four layers: application, transport, internet, and network access. Of these four layers, it is the internet layer that is responsible for routing messages. The session layer is not part of the TCP/IP model but is rather part of the OSI model. 41. 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?42. Which PDU format is used when bits are received from the network medium by the NIC of a host?file Explanation: When received at the physical layer of a host, the bits are formatted into a frame at the data link layer. A packet is the PDU at the network layer. A segment is the PDU at the transport layer. A file is a data structure that may be used at the application layer. 43. Refer to the exhibit.ServerB is attempting to contact HostA. Which two statements correctly identify the addressing that ServerB will generate in the process? (Choose two.)ServerB will generate a packet with the destination IP address of RouterB. 44. Which method allows a computer to react accordingly when it requests data from a server and the server takes too long to respond?encapsulation 45. A web client is receiving a response for a web page from a web server. From the perspective of the client, what is the correct order of the protocol stack that is used to decode the received transmission?Ethernet, IP, TCP, HTTP* Explanation: 46. Which two OSI model layers have the same functionality as a single layer of the TCP/IP model? (Choose two.)data link* 47. At which layer of the OSI model would a logical address be added during encapsulation?physical layer 48. What is a characteristic of multicast messages?They are sent to a select group of hosts.* Explanation: Multicast is a one-to-many type of communication. Multicast messages are addressed to a specific multicast group. 49. Which statement is correct about network protocols?Network protocols define the type of hardware that is used and how it is mounted in racks. 50. What is an advantage of network devices using open standard protocols?Network communications is confined to data transfers between devices from the same vendor. 51. Which device performs the function of determining the path that messages should take through internetworks?a router* Explanation: A router is used to determine the path that the messages should take through the network. A firewall is used to filter incoming and outgoing traffic. A DSL modem is used to provide Internet connection for a home or an organization. 52. Open the PT Activity.Perform the tasks in the activity instructions and then answer the question.What is the IP address of the switch virtual interface (SVI) on Switch0?192.168.5.10* Explanation: After the enable command is issued, the show running-configuration command or the show ip interfaces brief command will display the IP address of the switch virtual interface (SVI). 53. Why would a Layer 2 switch need an IP address?to enable the switch to send broadcast frames to attached PCs Explanation: A switch, as a Layer 2 device, does not need an IP address to transmit frames to attached devices. However, when a switch is accessed remotely through the network, it must have a Layer 3 address. The IP address must be applied to a virtual interface rather than to a physical interface. Routers, not switches, function as default gateways. 54. Refer to the exhibit.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. Explanation: In order to enter global configuration mode, the command configure terminal, or a shortened version such as config t, must be entered from privileged EXEC mode. In this scenario the administrator is in user EXEC mode, as indicated by the > symbol after the hostname. The administrator would need to use the enable command to move into privileged EXEC mode before entering the configure terminal command. 55. What term describes a network owned by one organization that provides safe and secure access to individuals who work for a different organization?Extranet* 56. What term describes storing personal files on servers over the internet to provide access anywhere, anytime, and on any device?Cloud* 57. What term describes a network where one computer can be both client and server?peer-to-peer* 58. What term describes a type of network used by people who work from home or from a small remote office?SOHO network* 59.
