Preventive/Technical controls are also known as logical controls and can be built into the operating system, be software applications, or can be supplemental hardware/software units.

The answer: Power line conditioning is a protective measure against noise. It helps to ensure the transmission of clean power. Source: KRUTZ, Ronald L. & VINES, Russel D., The CISSP Prep Guide: Mastering the Ten Domains of Computer Security, page 334.

A brute force attack is an attempt to use all combinations of key patterns to decipher a message. The other three attacks are commonly used to create a Denial of Service (DoS).
*Ping of Death, exploits ICMP by sending an illegal ECHO packet of >65K
octets of data, which can cause an overflow of system variables and
lead to a system crash.
*SMURF, is a type of attack using spoofed ICMP ECHO requests to broadcast addresses, which
the routers attempt to propagate, congesting the network. Three participants are required for a
SMURF attack: the attacker, the amplifying
network, and the victim.
*a TCP SYN flood attack, generates phony TCP SYN packets from random IP addresses at a
rapid rate to fill up the connection queue and stop the system from accepting legitimate users.

The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates information from domain names with each of the assigned entities.
Most prominently, it translates easily memorized domain names to the numerical IP addresses needed for locating computer services and devices worldwide. The Domain
Name System is an essential component of the functionality of the Internet. This article presents a functional description of the Domain Name System.
For your exam you should know below information general Internet terminology:
Network access point - Internet service providers access internet using net access point.A
Network Access Point (NAP) was a public network exchange facility where Internet service providers (ISPs) connected with one another in peering arrangements. The NAPs were a key component in the transition from the 1990s NSFNET era (when many networks were government sponsored and commercial traffic was prohibited) to the commercial Internet providers of today. They were often points of considerable Internet congestion.
Internet Service Provider (ISP) - An Internet service provider (ISP) is an organization that provides services for accessing, using, or participating in the Internet. Internet service providers may be organized in various forms, such as commercial, community-owned, non- profit, or otherwise privately owned. Internet services typically provided by ISPs include
Internet access, Internet transit, domain name registration, web hosting, co-location.
Telnet or Remote Terminal Control Protocol -A terminal emulation program for TCP/IP networks such as the Internet. The Telnet program runs on your computer and connects your PC to a server on the network. You can then enter commands through the Telnet program and they will be executed as if you were entering them directly on the server console. This enables you to control the server and communicate with other servers on the network. To start a Telnet session, you must log in to a server by entering a valid username and password. Telnet is a common way to remotely control Web servers.
Internet Link- Internet link is a connection between Internet users and the Internet service provider.
Secure Shell or Secure Socket Shell (SSH) - Secure Shell (SSH), sometimes known as
Secure Socket Shell, is a UNIX-based command interface and protocol for securely getting access to a remote computer. It is widely used by network administrators to control Web and other kinds of servers remotely. SSH is actually a suite of three utilities - slogin, ssh, and scp - that are secure versions of the earlier UNIX utilities, rlogin, rsh, and rcp. SSH commands are encrypted and secure in several ways. Both ends of the client/server connection are authenticated using a digital certificate, and passwords are protected by being encrypted.

Internet or a private network. It associates information from domain names with each of the assigned entities. Most prominently, it translates easily memorized domain names to the numerical IP addresses needed for locating computer services and devices worldwide. The

File Transfer Protocol (FTP) - The File Transfer Protocol or FTP is a client/server application that is used to move files from one system to another. The client connects to the FTP server, authenticates and is given access that the server is configured to permit.
FTP servers can also be configured to allow anonymous access by logging in with an email address but no password. Once connected, the client may move around between directories with commands available
Simple Mail Transport Protocol (SMTP) - SMTP (Simple Mail Transfer Protocol) is a
TCP/IP protocol used in sending and receiving e-mail. However, since it is limited in its ability to queue messages at the receiving end, it is usually used with one of two other protocols, POP3 or IMAP, that let the user save messages in a server mailbox and download them periodically from the server. In other words, users typically use a program that uses SMTP for sending e-mail and either POP3 or IMAP for receiving e-mail. On Unix- based systems, send mail is the most widely-used SMTP server for e-mail. A commercial package, Send mail, includes a POP3 server. Microsoft Exchange includes an SMTP server and can also be set up to include POP3 support.
The following answers are incorrect:

Explanation/Reference:
Explanation:
Administrative controls are security mechanisms that are management's responsibility and referred to as
"soft" controls. These controls include the development and publication of policies, standards, procedures, and guidelines; the screening of personnel; security-awareness training; the monitoring of system activity; and change control procedures.
Logical access control mechanisms are not an example of administrative controls. They are an example of a "Logical control" also known as a "Technical control".
Incorrect Answers:
B: Screening of personnel is an example of an administrative control.
C: Development of policies, standards, procedures and guidelines is an example of an administrative control.
D: Change control procedures are an example of an administrative control.
