of service to different types of traffic.
2.
Refer to the exhibit. Which term correctly identifies the device type that is
included in the area B? intermediary
3. Which definition describes the term Internet? a network of networks that connects countries
around the world
4. What are two benefits of collaboration and video-on-demand applications? (Choose two.)
1.providing a richer e-learning environment; 2. providing better social media opportunities
5. How does BYOD change the way in which businesses implement networks? BYOD provides flexibility
in where and how users can access network resources.
6. For which three reasons was a packet-switched connectionless data communications technology used
when developing the Internet? (Choose three.)1. It can rapidly adapt to the failure of network devices
and communication links. 2. Data packets can travel through the network using multiple different
paths. 3. Network devices dynamically decide on the best available path to forward each packet.
7. Match the definition to the network characteristic. (Not all options are used.) managing the delay and
packet loss parameters on a network to provide acceptable quality levels for end-to-end
communications: quality of service; maintaining the privacy and confidentiality needs of
communications: security; expanding quickly to support new users and applications without impacting
the performance of the service being delivered to existing users: scalability; limiting the impact of a
hardware or software failure and providing quick recovery if such a failure occurs: fault tolerance
8. An _Intranet is a private connection of LANs and WANs that belongs to an organization, and is
designed to be accessible only by the members and employees of the organization, or others with
authorization.
9. Which statement describes a scalable network? A network that can expand and adapt easily to
provide new services.
10. Which statement characterizes a podcasting tool? People deliver their own recordings to a wide
audience through subscriptions on websites.

11. The farther you are from the central office when utilizing a DSL connection, the slower the
connection speed.
12. Which internal factor could affect successful communication across the network? the complexity of
the message
13. Match each description to its network type. (Not all options are used.) WAN-provides access to
other networks over a wide geographical area; LAN-connects users and end devices in a single building;
WLAN-wirelessly interconnects users and end points in a small geographical area; SAN-designed to
support file servers and provide data storage, retrieval and replication
14. Which type of network design combines voice, video, and data on the same communication
channel? A converged network
Chapter 2
1. To save time, IOS commands may be partially entered and then completed by typing which key or key
combination? Tab
2. In a Cisco device, where is the IOS file stored prior to system startup? Flash
3. Why would a network administrator use the CLI of the Cisco IOS? to add a password to a Cisco
network device
4. A network administrator is tasked to perform the initial configuration of a new switch that has just
come out of the box. Which out-of-band connection should be used for the task? A console port
connection
5.
Refer to the exhibit. Which element of IOS syntax is the expression MainOffice? An argument
6. In order to verify the IP protocol stack of a device without placing any traffic on the network, an
administrator should ping the IP address 127.0.0.7.
7. Which three pieces of information must be specified on a computer to allow that computer to send
and receive information across networks? (Choose three.) 1. IP address; 2. Subnet mask; 3. Default
gateway
8. Which network service automatically assigns IP addresses to devices on the network? DHCP

on a switch to display the exhibited output? Show IP interface brief
10. A network administrator issues the disable command at the privileged EXEC prompt. What is the
effect of this command? The CLI session is changed from the privileged EXEC to the user EXEC mode.

Refer to the exhibit. What can be concluded from this exhibited output? The service password-
encryption command was issued on this device.
12. Which statement describes a feature of an IOS host name configuration? It does not allow spaces
13. Which two statements are true regarding the user EXEC mode? (Choose two.) 1. This is the default
mode on an unconfigured router when first powered up.; 2. Only some aspects of the router
configuration can be viewed.
14. Match the description to the term. (Not all options are used.) ping-checks connectivity; DHCP-allows
end devices to have IP information automatically configured; DNS-translates web addresses and
hostnames to IP addresses; SSH-provides a secure remote login session to a device
15. A network administrator has forgotten the argument of an IOS command. How would the
administrator get help from the IOS CLI to complete the command correctly? Type the command and
then press the ? key.
