Answer:

Centrifugation.

Explanation:

When the liquid is spun rapidly, the denser particles are forced to the bottom and the lighter particles stay at the top. This principle is used in centrifugation.

Centrifugation can be defined as the process of separating particles from a liquid solution according to density, shape, size, viscosity through the use of a centrifugal force. In order to separate these particles, the particles are poured into a liquid and placed in a centrifuge tube. A centrifuge is an electronic device used for the separation of particles in liquid through the application of centrifugal force. Once the centrifuge tube is mounted on the rotor of the centrifuge, it is spun rapidly at a specific speed thereby separating the solution; denser particles are forced to the bottom (by moving outward in the radial direction) and the lighter particles stay at the top as a result of their low density.

Which method allows a computer to react accordingly when it requests data from a server and the server takes too long to respond
Rina8888 [55]

Answer:

A. Request timeout.

Explanation:

The end devices like the computer systems in a network seeks to share resources with one another and/ or request resources from central server.

With this, there are two ways computers in a network can communicate. They are peer to peer network communication and client-server network communication.

The client-server communication requires a dedicated central server where computers in the network require data. Peer to peer describes a network where computers serve as both client and server to each other.

Request timeout is a message sent to a source when the time to live period (TTL) of a packet expires.

Wendy is an attacker who recently gained access to a vulnerable web server running Microsoft Windows. What command can she use t
VikaD [51]

Answer:

I would say that if she is connected to the server and has grained access to the server, Wendy would have to use the command shortkey win+r (to run) or she could just use the "Type here to search" function.

Then you can type the words "cmd" to bring up the command prompt

Lastly, she would need to use the protocol scp to transfer files. Wendy might need to include a destination for the files to be directed to.

The Company management has asked that you compare the OSSTMM and the PTES to determine which methodology to select for internal
Sonbull [250]

Answer:

The basic comaprism of OSSTMN and PTES includes the following: OSSTMN is more theoretical, security assessment methodology, and Metrics based why PTES is technology oriented, penetration testing methodology ,  extended analysis of all stages

Explanation:

Solution

Penetration testing has several methodologies which include :OSSTMM and PTES  

The comparison between OSSTMM and PTES is stated as follows:

OSSTMM:                                                

Security assessment methodology

More Theoretical  

Metrics based

PTES :

Technology oriented

Penetration testing methodology

Extended analysis of all stages

Now,

There are 7 stages which is used to define PTES for penetration testing.(Penetration Testing Execution Standard)

  • Pre-engagement Interactions
  • Intelligence Gathering
  • Threat Modeling
  • Vulnerability Analysis
  • Exploitation
  • Post Exploitation
  • Reporting

Now,

The OSSTMM is used to obtain security metrics and performing penetration testing .The OSSTMM provides transparency to those who have inadequate security policies and configurations.

The OSSTMM includes the entire risk assessment process starting from requirement analysis to report creation.

Six areas are covered by OSSTMM which are:

  • Information security
  • Process security
  • Internet technology security
  • Communications security
  • Wireless security
  • Physical security

Ghella [55]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The correct answer to this question is an online decision support system. Because the decision support systems process the data, evaluate and predict the decision, and helps the decision-makers,  and offer real-time information immediately in making the decision in an organization. So the correct answer to this question is the decision supports system.

Why other options are not correct

Because the transaction processing system can only process the transaction and have not the capability to make the decision for the future. Office support processing system support office work, while the batch processing system process the task into the batch without user involvement.   however, online executive processing does not make decisions and offer timely information to decision-makers in an organization.
