Domain name space consists of a tree of domain names. Each node or leaf in the tree has zero or more resource records, which hold information associated with the domain name. The tree sub- divides into zones starting at the root zone.

Answer: B is incorrect. The definitive descriptions of the rules for forming domain names appear in RFC 1035, RFC 1123, and RFC 2181. A domain name consists of one or more parts, technically called labels that are conventionally

concatenated, and delimited by dots.

Answer: C is incorrect. Domain Name System (DNS) is a distributed hierarchical naming system for computers, services, or other resources connected to the Internet or a private network. It associates various information with domain names

assigned to each of the participants.

Answer: D is incorrect. An authoritative name server is a name server that gives answers that have been configured by an original source, for example, the domain administrator or by dynamic DNS methods, in contrast to the answers that

were obtained via a regular DNS query to one more name server. An authoritative-only name server only returns answers to the queries about domain names that have been specifically configured by the administrator.

A stealth virus is a file virus. It infects the computer and then hides itself from detection by antivirus software. It uses various mechanisms to avoid detection by antivirus software. It hides itself in computer memory after infecting the computer.

It also masks itself from applications or utilities. It uses various tricks to appear that the computer has not lost any memory and the file size has not been changed. The virus may save a copy of original and uninfected data. When the anti-virus

program tries to check the files that have been affected, the virus shows only the uninfected data. This virus generally infects .COM and .EXE files. Answer: B is incorrect. A boot sector virus infects the master boot files of the hard disk or

floppy disk. Boot record programs are responsible for booting the operating system and the boot sector virus copies these programs into another part of the hard disk or overwrites these files. Therefore, when the floppy or the hard disk boots,

the virus infects the computer.

Answer: C is incorrect. A macro virus is a virus that consists of a macro code which infects the system. A Macro virus can infect a system rapidly. Since this virus has VB event handlers, it is dynamic in nature and displays random activation.

The victim has only to open a file having a macro virus in order to infect the system with the virus. DMV, Nuclear, and Word Concept are some good examples of macro viruses.

Answer: A is incorrect. The EICAR (EICAR Standard Anti-Virus Test File) virus is a file that is used to test the response of computer antivirus (AV) programs. The rationale behind it is to allow people, companies, and antivirus programmers to

test their software without having to use a real computer virus that could cause actual damage should the antivirus not respond correctly. The file is simply a text file of either 68 or 70 bytes that is a legitimate executable file called a COM file

that can be run by Microsoft operating systems and some work-alikes (except for 64-bit due to 16-bit limitations), including OS/2. When executed, it will print "EICAR- STANDARD-ANTIVIRUS-TEST-FILE!" and then stop. The string used in

the EICAR virus is as follows:
