What is penetration test?

A penetration test, also known as a pen test or ethical hacking, is a legally sanctioned simulated cyberattack on a computer system undertaken to examine the system's security; this is not to be confused with a vulnerability assessment. The test is carried out to discover vulnerabilities, such as the possibility of unauthorised parties gaining access to the system's features and data, as well as strengths, allowing a full risk assessment to be carried out. Typically, the process determines the target systems and a specific goal, then evaluates available information and employs various methods to achieve that goal. A penetration test target can be either white or black.

The long-term rate host a sends data to host b is 100 Mbps, Host A's sending rate can be at most 100 Mbps. Still, Host A sends data into the receive buffer faster than Host B can remove the data.

Transmission Control Protocol (TCP) means a standard that describes how to establish and maintain a network conversation by which applications can exchange data. TCP works with the Internet Protocol (IP), which describes how computers send packets of data to each other.

Based on the story above, the receive buffer fills up at a rate of roughly 40 Mbps. If the buffer is full, Host B signals to Host A to stop addressing data by setting RcvWindow = 0; Host A then stops addressing until it receives a TCP segment with RcvWindow > 0. Host A will start sending as a function of the RcvWindow values it receives from Host B and also thus repeatedly stop.

Asymmetrical elements may not be equally distributed; however, they can still promote some form of equilibrium by placing numerous small items on one side of the page and just a few large objects on the other side. The correct option is D.

Asymmetrical balance occurs when different visual images are used on either side of a design and the image still appears balanced.

A design must have unequal visual weight on either side to be considered asymmetrical, but those unequal visuals must balance each other.

Although asymmetrical elements are not evenly distributed, they can still promote some form of equilibrium by placing many small objects on one side of the page and only a few large objects on the other.

Conditional formatting makes it easy to highlight certain values or make particular cells easy to identify. This changes the appearance of a cell range based on a condition (or criteria). You can use conditional formatting to highlight cells that contain values that meet a certain condition.
