_________________ partitions the physical hardware and presents this hardware to virtual machines.
- A.
Physical hardware
- B.
Hypervisor
- C.
Virtual operating system
- D.
Host operating system
Correct Answer
A. pHysical hardwareExplanation
The physical hardware is responsible for providing the underlying resources such as CPU, memory, and storage to virtual machines. It partitions these resources and presents them to the virtual machines, allowing them to run and operate as if they were using dedicated hardware. The physical hardware acts as the foundation for the virtualization environment, enabling the creation and management of virtual machines.Rate this question:

"Access privileges granted to a user, program or process" is called as ________
- A.
Authentication
- B.
Authorization
- C.
Confidentiality
- D.
Integrity
Correct Answer
B. AuthorizationExplanation
Authorization refers to the access privileges that are granted to a user, program, or process. It determines what actions or resources a user is allowed to access or perform within a system. Authentication, on the other hand, is the process of verifying the identity of a user or entity. Confidentiality refers to the protection of sensitive information from unauthorized access. Integrity refers to the assurance that data remains intact and unaltered. Therefore, the correct answer for this question is Authorization.Rate this question:

The concept of using same key for encryption and decryption is called __________
- A.
Asymmetric key system
- B.
Substitution cipher
- C.
Symmetric key system
- D.
Caesar cipher
Correct Answer
C. Symmetric key systemExplanation
The concept of using the same key for both encryption and decryption is known as a symmetric key system. In this system, the sender and receiver use the same secret key to encrypt and decrypt the message, ensuring confidentiality. This method is faster and more efficient than asymmetric key systems, where different keys are used for encryption and decryption. Substitution cipher and Caesar cipher are specific examples of symmetric key systems, but the term "symmetric key system" encompasses a broader range of encryption techniques.Rate this question:

In symmetric key systems, ____________ key is used to generate ciphertext and plain text from the message.
- A.
NOTÂ
- B.
XOR
- C.
AND
- D.
NAND
Correct Answer
B. XORExplanation
In symmetric key systems, the XOR key is used to generate ciphertext and plaintext from the message. XOR (exclusive OR) is a logical operation that outputs true only when the inputs differ. In encryption, the XOR operation is used to combine the message with the key, resulting in the ciphertext. To decrypt the ciphertext and obtain the original message, the same XOR operation is applied using the same key. XOR is commonly used in symmetric key cryptography due to its simplicity and effectiveness in providing confidentiality.Rate this question:

Select the number of levels found in the Domain Name Server (DNS).
- A.
128
- B.
129
- C.
127
- D.
126
Correct Answer
C. 127Explanation
The number of levels found in the Domain Name Server (DNS) is 127. This is because the DNS follows a hierarchical structure, with each level representing a different domain. The top-level domain (TLD) is the highest level, followed by second-level domains, subdomains, and so on. The DNS can have a maximum of 127 levels, allowing for a wide range of hierarchical organization within the domain system.Rate this question:

Each computer with internet access is assigned __________________
- A.
Machine address
- B.
Internet Protocol (IP)
- C.
Internet availability
- D.
Network Interface card
Correct Answer
B. Internet Protocol (IP)Explanation
Each computer with internet access is assigned an Internet Protocol (IP) address. This address serves as a unique identifier for the computer on the internet. It allows the computer to send and receive data across the network, enabling communication with other devices and access to online resources. The IP address plays a crucial role in routing data packets and ensuring that they reach the intended destination on the internet.Rate this question:

Records maintained in DNS are
- A.
A
- B.
NX
- C.
NS
- D.
MX
- E.
MS
Correct Answer(s)
A. A
C. NS
D. MXExplanation
DNS (Domain Name System) maintains various types of records to provide information about domain names. The A record maps a domain name to its corresponding IP address. The NS record specifies the authoritative name servers for a domain. The MX record identifies the mail servers responsible for accepting incoming emails for a domain. Therefore, the correct answer includes A, NS, and MX as these are all types of records maintained in DNS.Rate this question:

______________ are network devices or software that separates one trusted network from an untrusted network by means of rule-based filtering of network traffic.
- A.
Windows firewall
- B.
Phishing
- C.
Firewalls
- D.
Windows security
Correct Answer
C. FirewallsExplanation
Firewalls are network devices or software that separate one trusted network from an untrusted network by filtering network traffic based on predefined rules. They act as a barrier between the internal network and the outside world, preventing unauthorized access and protecting the network from potential threats. Firewalls monitor incoming and outgoing traffic, allowing or blocking specific types of data based on the configured rules. They are an essential component of network security, ensuring the integrity and confidentiality of the network.Rate this question:

Parts of windows token are
- A.
Identity
- B.
Access control
- C.
Impersonate
- D.
Privileges
- E.
Type
- F.
Thread access
- G.
Process access
Correct Answer(s)
A. Identity
B. Access control
D. Privileges
E. TypeExplanation
The given answer includes the different parts of a Windows token. A Windows token is a data structure that contains information about a user or a group, including their identity, access control settings, privileges, and type. The identity part of the token specifies the user or group it represents. The access control part contains the security descriptors that define the permissions granted to the user or group. The privileges part specifies the additional rights that the user or group has. The type part indicates whether the token represents a user or a group.Rate this question:

Thread specific rights have ___________ number of access rights.
- A.
12
- B.
14
- C.
13
Correct Answer
C. 13Explanation
Thread specific rights have a specific number of access rights that are unique to each thread. These access rights enable the thread to perform specific actions or operations within a program or system. In this case, the correct answer is 13, indicating that thread specific rights have 13 access rights.Rate this question:
