   •  BYOD
   •  cloud computing
   •  video conferencing
   •  powerline networking

   
   

   Explanation: BYOD, or bring your own device, is a trend in networking where users are allowed to use personal devices and tools on business and campus networks.

2. 2.What is a characteristic of a converged network?

   •  A converged network requires a separate network infrastructure for each type of communication technology
   •  it delivers data, voice, and video over the same network infrastructure
   •  it limits the impact of a failure by minimizing the number of devices affected
   •  it provides only one path between the source and destination of a message

   
   

   Explanation: A converged network is one in which multiple technologies such as data, telephone, and video are all delivered on the same network infrastructure.

1. A company is contemplating whether to use a client/server or a peer-to-peer network. What are three characteristics of a peer-to-peer network? (Choose three.)

   • better security
   • easy to create
   • better device performance when acting as both client and server
   • lacks centralized administration
   • less cost to implement
   • scalable
     

     Explanation: Because network devices and dedicated servers are not required, peer-to-peer networks are easy to create, less complex, and have lower costs. Peer-to-peer networks also have no centralized administration. They are less secure, not scalable, and those devices acting as both client and server may perform slower.

2. Which device performs the function of determining the path that messages should take through internetworks?

   • a router
   • a firewall
   • a web server
   • a DSL modem
     

     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.

3. 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
   • the cost of the end devices utilized in the network
   • the distance the selected medium can successfully carry a signal
   • the number of intermediary devices installed in the network
   • the environment where the selected medium is to be installed
     

     Explanation: Criteria for choosing a network medium are the distance the selected medium can successfully carry a signal, the environment in which the selected medium is to be installed, the amount of data and the speed at which the data must be transmitted, and the cost of the medium and its installation.

4. Which two statements describe intermediary devices? (Choose two.)

   • Intermediary devices generate data content.
   • Intermediary devices alter data content.
   • Intermediary devices direct the path of the data.
   • Intermediary devices connect individual hosts to the network.
   • Intermediary devices initiate the encapsulation process.
     

     Explanation: Applications on end devices generate data, alter data content, and are responsible for initiating the encapsulation process.

5. What are two functions of end devices on a network? (Choose two.)

   • They originate the data that flows through the network.
   • They direct data over alternate paths in the event of link failures.
   • They filter the flow of data to enhance security.
   • They are the interface between humans and the communication network.
   • They provide the channel over which the network message travels.
     

     Explanation: End devices originate the data that flows through the network. Intermediary devices direct data over alternate paths in the event of link failures and filter the flow of data to enhance security. Network media provide the channel through which network messages travel.

6. Which area of the network would a college IT staff most likely have to redesign as a direct result of many students bringing their own tablets and smartphones to school to access school resources?

   • extranet
   • intranet
   • wired LAN
   • wireless LAN
   • wireless WAN
     

     Explanation: An extranet is a network area where people or corporate partners external to the company access data. An intranet simply describes the network area that is normally accessed only by internal personnel. The wired LAN is affected by BYODs (bring your own devices) when the devices attach to the wired network. A college wireless LAN is most likely used by the tablet and smartphone. A wireless WAN would more likely be used by college students to access their cell provider network.

7. What type of network must a home user access in order to do online shopping?

   • an intranet
   • the Internet
   • an extranet
   • a local area network
     

     Explanation: Home users will go online shopping over the Internet because online vendors are accessed through the Internet. An intranet is basically a local area network for internal use only. An extranet is a network for external partners to access certain resources inside an organization. A home user does not necessarily need a LAN to access the Internet. For example, a PC connects directly to the ISP through a modem.

8. 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
   • the Internet
   • an extranet
   • a local area network
     

     Explanation: Intranet is a term used to refer to a private connection of LANs and WANs that belongs to an organization. An intranet is designed to be accessible only by the organization’s members, employees, or others with authorization.

9. Which two connection options provide an always-on, high-bandwidth Internet connection to computers in a home office? (Choose two.)

   • cellular
   • DSL
   • satellite
   • cable
   • dial-up telephone
     

     Explanation: Cable and DSL both provide high bandwidth, an always on connection, and an Ethernet connection to a host computer or LAN.

10. Which two Internet connection options do not require that physical cables be run to the building? (Choose two.)

    • DSL
    • cellular
    • satellite
    • dialup
    • dedicated leased line
      

      Explanation: Cellular connectivity requires the use of the cell phone network. Satellite connectivity is often used where physical cabling is not available outside the home or business.

11. Which term describes the state of a network when the demand on the network resources exceeds the available capacity?

    • convergence
    • congestion
    • optimization
    • synchronization
      

      Explanation: When the demand on the network resources exceeds the available capacity, the network becomes congested. A converged network is designed to deliver multiple communication types, such as data, video and voice services, using the same network infrastructure.

12. What type of network traffic requires QoS?

    • email
    • on-line purchasing
    • video conferencing
    • wiki
      

      Explanation: Video conferencing utilizes real-time audio and video communications. Both of these are time-sensitive and bandwidth-intensive forms of communication that require quality of service to be active on the network. QoS will ensure an uninterrupted user experience.

13. Which expression accurately defines the term bandwidth?

    • a method of limiting the impact of a hardware or software failure on the network
    • a measure of the data carrying capacity of the media
    • a state where the demand on the network resources exceeds the available capacity
    • a set of techniques to manage the utilization of network resources
      

      Explanation: A method of limiting the impact of a hardware or software failure is fault tolerance. A measure of the data carrying capacity is bandwidth. A set of techniques to manage the utilization of network resources is QoS. A state where the demand on the network resources exceeds the available capacity is called congestion.

14. A network administrator is implementing a policy that requires strong, complex passwords. Which data protection goal does this policy support?

    • data integrity
    • data quality
    • data confidentiality
    • data redundancy
      

      Explanation: A security policy requiring strong, complex passwords contributes to data confidentiality because only authorized users can access the data.

15. Which statement describes a characteristic of cloud computing?

    • A business can connect directly to the Internet without the use of an ISP.
    • Applications can be accessed over the Internet by individual users or businesses using any device, anywhere in the world.
    • Devices can connect to the Internet through existing electrical wiring.
    • Investment in new infrastructure is required in order to access the cloud.
      

      Explanation: Cloud computing allows users to access applications, back up and store files, and perform tasks without needing additional software or servers. Cloud users access resources through subscription-based or pay-per-use services, in real time, using nothing more than a web browser.

16. What is the Internet?

    • It is a network based on Ethernet technology.
    • It provides network access for mobile devices.
    • It provides connections through interconnected global networks.
    • It is a private network for an organization with LAN and WAN connections.
      

      Explanation: The Internet provides global connections that enable networked devices (workstations and mobile devices) with different network technologies, such as Ethernet, DSL/cable, and serial connections, to communicate. A private network for an organization with LAN and WAN connections is an intranet.

17. Which statement describes the use of powerline networking technology?

    • New “smart” electrical cabling is used to extend an existing home LAN.
    • A home LAN is installed without the use of physical cabling.
    • A device connects to an existing home LAN using an adapter and an existing electrical outlet.
    • Wireless access points use powerline adapters to distribute data through the home LAN.
      

      Explanation: Powerline networking adds the ability to connect a device to the network using an adapter wherever there is an electrical outlet.​ The network uses existing electrical wiring to send data. It is not a replacement for physical cabling, but it can add functionality in places where wireless access points cannot be used or cannot reach devices.​

18. What security violation would cause the most amount of damage to the life of a home user?

    • denial of service to your email server
    • replication of worms and viruses in your computer
    • capturing of personal data that leads to identity theft
    • spyware that leads to spam emails
      

      Explanation: On a personal PC, denial of service to servers, worms and viruses, and spyware producing spam emails can be annoying, invasive, and frustrating. However, identity theft can be devastating and life altering. Security solutions should be in place on all personal devices to protect against this type of threat.

19. 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
    • installing a wireless network
    • installing antivirus software
    • implementing an intrusion detection system
    • adding a dedicated intrusion prevention device
      

      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.

20. A           converged         network is capable of delivering voice, video, text, and graphics over the same communication channels.

21. Fill in the blank.

    The acronym      byod       refers to the policy that allows employees to use their personal devices in the business office to access the network and other resources.

      CCNA1 Chapter 1 v5.1 002 Answer

      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.

24. Match the definition to the security goal. (Not all options are used.)

      CCNA1 Chapter 1 v5.1 003 Answer

      Explanation: Data integrity verifies that the data has not been altered on the trip between the sender and the receiver. A field calculated by the sender is recalculated and verified to be the same by the receiver. Passwords and authorization maintain control over who has access to personal data. Redundant devices and links attempt to provide 99.999% availability to users. Integrity is made possible by requiring validation of the sender, not the destination. VPNs are not the only secure method by which data can be transferred confidentially.
