CCNA 1 Chapter 1 v6 Exam Answers

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

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

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

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.

What is the Internet?

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.

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

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.

Match each characteristic to its corresponding Internet connectivity type. (Not all options are used.)

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

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.

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

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

What type of network traffic requires QoS?

Which statement describes the use of powerline networking technology?

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.​

Which statement describes a characteristic of cloud computing?

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.

Match the description to the form of network communication. (Not all options are used.)

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

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?

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.

Which expression accurately defines the term bandwidth?

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.

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?

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.

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.)

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.

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

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

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

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.

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

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

When one network is used for all types of communication such as voice, video, text, and graphics, the network is referred to as a converged network.

A user is implementing security on a small office network. Which two actions would provide the minimum security requirements for this network? (Choose two.)

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.

What two criteria are used to help select a network medium from various network media? (Choose two.)

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.

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

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.
