QUESTION: 37

John works as a Network Administrator for NetPerfect Inc. The company has a Windows-based network. Over the last few weeks, the connectivity speed of the company has dropped down to 50 Mbps. John also receives many queries from employees of the company regarding slow Internet connection. The proposed data transmission speed is up to 1 Gbps. To increase the connectivity speed, John decides to upgrade the network.
Which of the following networking standards will he use to accomplish the task?

10 Gigabit Ethernet
10Base-FL
Fast Ethernet
Gigabit Ethernet

Answer(s): D

Explanation:

Gigabit Ethernet are network standards that can achieve speed up to 1Gbps. IEEE standard for Gigabit Ethernet is IEEE 802.3z for 1000BASE-LX/SX and IEEE 802.3ab for 1000BASE-T. The cable type used in Gigabit Ethernet is fiber-optic.
Answer option B is incorrect. 10BASE-FL is an IEEE baseband specification of Ethernet. It supports the maximum speed of 10Mbps. It uses fiber optic cables and supports the maximum cable length of 2000 meters. It uses different connectors, such as ST or SC connectors.
Answer option A is incorrect. The 10 Gigabit Ethernet standard (also known as 10GE, 10GbE, or 10 GigE) was first published in 2002 as IEEE Std 802.3ae-2002. It defines a version of Ethernet with a nominal data rate of 10 Gbit/s, ten times as fast as Gigabit Ethernet. 10 Gigabit Ethernet supports only full duplex links which can be connected by switches. Half duplex operation and CSMA/CD (carrier sense multiple access with collision detect) are not supported in 10GbE.
Answer option C is incorrect. Fast Ethernet is a local area network (LAN) transmission standard that provides a data rate of 100 megabits per second (referred to as '100BaseT'). Workstations with an existing 10 megabit per second (10BaseT) Ethernet card can be connected to a Fast Ethernet network. Fast Ethernet is a collective term for a number of Ethernet standards that carry traffic at the nominal rate of 100 megabits per second, against the original Ethernet speed of 10 megabits per second.

QUESTION: 38

Computers which are connected through a network can share resources as hard drives, printers, scanners, etc. with each other.
The functionality of all client computers on the network depend on the main server computer.
In a network environment, system maintenance can be performed from one central location.
A user can send files from one computer to another quite easily.

Answer(s): A,C,D

Explanation:

A computer network, often simply referred to as a network, is a collection of computers and devices connected by communications channels that facilitates communications among users and allows users to share resources with other users. Some of the benefits of a computer network are as follows:
Computers which are connected through a network can share resources as hard drives, printers, scanners, etc. with each other.
A user can send files from one computer to another quite easily.
A user can connect all the computers which are connected through a network to the internet by using a single line. So it means that one can save the connection cost for each computer but your internet connection must be fast. If a user wants to access data from another computer which is the part of network then he can access data from that computer. Users can run those programs which are not installed on their computers but are installed on any other user's computer. In a network environment, administrators can take backups from one central location of all computers that are on the network. In a network environment, system maintenance can be performed from one central location.

QUESTION: 39

Which of the following policies is applied by the owner/manager of a network to restrict the ways in which the network site or system may be used?

Enterprise policy
Password policy
Due care policy
Acceptable use policy

Answer(s): D

Explanation:

An acceptable use policy (AUP) also known as acceptable usage policy or Fair Use Policy is a set of rules applied by the owner/manager of a network, Website or large computer system that restrict the ways in which the network site or system may be used. AUP documents are written for corporations, businesses, universities, schools, Internet service providers, and Website owners often to reduce the potential for legal action that may be taken by a user, and often with little prospect of enforcement. Acceptable use to the framework of information security policies. It should refer users to the more comprehensive security policy where relevant. It should also, and very notably, define what sanctions will be applied if a user breaks the AUP. Compliance with this policy should, as usual, be measured by regular audits.
Answer option B is incorrect.
A password policy is a set of rules designed to enhance the computer security by encouraging users to employ strong passwords and use them properly.
A password policy is often part of an organization's official regulations and may be taught as part of security awareness training. The password policy may either be advisory or mandated by technical means.
Answer option C is incorrect. Due Care policy identifies the level of confidentiality of information on a computer. It specifies how the information is to be handled. The objective of this policy is to protect confidential records, the unauthorized disclosure of which creates a strong potential for liability.
Answer option A is incorrect. Enterprise policy includes site and content rules, and protocol rules. It can be applied to any array and can be augmented by the array's policy to enforce enterprise policies at branch and departmental levels, while allowing local administrators to further restrict access. Enterprise administrators can determine how local administrators in an organization should use the enterprise policy. Enterprise administrators can choose to deploy a restrictive policy in which no local array policy is configurable. Enterprise administrators might choose a liberal policy, which allows the local administrators to define any rule. In this case, no enterprise policy is applied to the array. Enterprise administrators might choose a mixed approach. In this approach, enterprise policies are applied and local administrators will be able to implement more restrictive rules further. The array policy defined at the local level cannot overwrite the enterprise policy and allows communication using other protocols.
