Problem 3

Question :

3. Fill in the blank.

An 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.

Answer Attempt :

Intranet

Correct Answer :

Intranet
intranet
Intra net
intra net
Intra-net
intra-net
INTRANET

Apparently, the answer attempt is one of the correct answer. It is just a matter of capitalization letter of the answer. But the most important thing is all of the correct answer refer to the same entity or term.

Explanation :

Fill in the blank.

Refer to the exhibit. This represents an example of an security threat to an organization.

Answer Attempt :

inside

Correct Answer :

internal

Fortunately, although the keyword is different, the online examination process consider the answer as the correct one. In this context, the evaluation process from the online examination consider ‘inside’ has a close or similar mmeaning with ‘internal’.

Explanation :

Refer to curriculum topic: 1.4.3
Typical internal security threats include weak or exposed passwords, lost or stolen devices, and malicious employees.

 

Problem 5

Question :

An employee wants to access the network of the organization remotely, in the safest possible way. What network feature would allow an employee to gain secure remote access to a company network?

Answer Option Choices :

ACL
IPS
VPN

Problem 6

Question :

A college is building a new dormitory on its campus. Workers are digging in the ground to install a new water pipe for the dormitory. A worker accidentally damages a fiber optic cable that connects two of the existing dormitories to the campus data center. Although the cable has been cut, students in the dormitories only experience a very short interruption of network services. What characteristic of the network is shown here?

Answer Option Choices :

quality of service (QoS)
scalability
security
fault tolerance
integrity

Correct Answer :

fault tolerance

Explanation :

Refer to curriculum topic: 1.3.2
Fault tolerance is the characteristic of a network which allows it to quickly respond to failures of network devices, media, or services. Quality of service refers to the measures taken to ensure that network traffic requiring higher throughput receives the required network resources. Scalability refers to the ability of the network to grow to accommodate new requirements. Security refers to protecting networks and data from theft, alteration, or destruction. Integrity refers to the completeness of something and is generally not used as a characteristic of networks in the same way as the other terms.

Answer Option Choices :

A single network that delivers voice, video, and data to a variety of devices.
Network services are delivered over a wide range of network platforms.
The network establishes separate communication channels for each network service.
The network uses different technologies for voice, video, and data.

Correct Answer :

A single network that delivers voice, video, and data to a variety of devices.

Explanation :

Refer to curriculum topic: 1.3.1
A converged network unifies different network services, such as streaming video, voice, and data, on a single platform and within a single infrastructure.

 

Problem 13

Question :

How does BYOD change the way in which businesses implement networks?

​

BYOD requires organizations to purchase laptops rather than desktops.
BYOD users are responsible for their own network security, thus reducing the need for organizational security policies.
BYOD devices are more expensive than devices that are purchased by an organization.
BYOD provides flexibility in where and how users can access network resources.

Correct Answer :

BYOD provides flexibility in where and how users can access network resources.

Refer to curriculum topic: 1.4.1
A BYOD environment requires an organization to accommodate a variety of devices and access methods. Personal devices, which are not under company control, may be involved, so security is critical. Onsite hardware costs will be reduced, allowing a business to focus on delivering collaboration tools and other software to BYOD users.

Problem 14

Question :

In which scenario would the use of a WISP be recommended?

Answer Option Choices :

an Internet cafe in a city
a farm in a rural area without wired broadband access
any home with multiple wireless devices
an apartment in a building with cable access to the Internet

Correct Answer :

a farm in a rural area without wired broadband access

Explanation :

Refer to curriculum topic: 1.4.2
Wireless Internet Service Providers (WISPs) are typically found in rural areas where DSL or cable access is not available. A dish or antenna on the property of the subscriber connects wirelessly to a WISP transmitter, eliminating the need for physical cabling outside the building.

Problem 14

Question :

Match the Internet connectivity type to the appropriate description or characteristic. (Not all options are used.)

Question List :

Question
Metro Ethernet	—
satellite	—
SDSL	—
cable	—
cellular	—

Answer Option Choices :

high-speed business class copper or fiber connection
requires a dish and clear line of sight for service
business class service that provides the same upload and download speeds over telephone lines
signal carried on the same copper or fiber medium as the television signal
access via the cell phone network
typically has very low bandwidth

Question List Option Choices :

Correct Answer :

Question
Metro Ethernet	high-speed business class copper or fiber connection
satellite	requires a dish and clear line of sight for service
SDSL	business class service that provides the same upload and download speeds over telephone lines
cable	signal carried on the same copper or fiber medium as the television signal
cellular	access via the cell phone network

Other Incorrect Match Options :

typically has very low bandwidth

Explanation :

Refer to curriculum topic: 1.2.4
DSL uses a high-speed modem to split the existing telephone line into voice, download, and upload signal channels. SDSL is a format of DSL that provides business class service featuring the same speeds for uploading and downloading. Cable uses the same coaxial or fiber optic cable that carries television signals into the home to provide Internet access. Satellite requires a clear line of sight and is affected by trees and other obstructions. Cellular access to the internet is provided by the cell phone network. Cellular provides access in areas that otherwise have no other form of access. Metro Ethernet is a dedicated business class of service that connects organizations to the internet via copper or fiber cable at speeds up to 10Gb/s.
