The two best practices of access control are A) implementing dynamic provisioning of access control capabilities for different subjects and B) ensuring there is only one execution path leading to the access of the object and putting an access control check anywhere on that path.
Dynamic provisioning of access control capabilities allows for efficient management of access control by granting or revoking permissions based on changing circumstances or requirements. This is especially important in large organizations with complex access control requirements.
Ensuring there is only one execution path leading to the access of an object and putting an access control check anywhere on that path helps to prevent unauthorized access by ensuring that every access attempt is checked against the access control policy. This can be achieved through the use of mandatory access control or role-based access control.
Provisioning based on individuals may not always provide the best flexibility to manage access control, as it can become cumbersome to manage a large number of individual permissions.
Access control checks should be performed only as necessary to reduce redundancy and improve efficiency, while still ensuring that access control policies are being enforced. So A and B are correct options.

How large is an impact crater compared to the size of the impactor?
A) 100 times larger
B) 1,000 times larger
C) 10 times larger
D) 10-20 percent larger
E) the same size
The answer is A) 100 times larger. An impact crater is typically about 100 times larger than the size of the impactor that created it.The size of an impact crater is typically much larger than the size of the impactor that created it. The exact ratio depends on a number of factors, such as the velocity, angle of impact, and composition of both the impactor and the target material.
However, in general, the size of an impact crater can be thousands or even millions of times larger than the size of the impactor.This is because when an impactor collides with a planetary surface, it releases a tremendous amount of energy that causes the target material to be ejected and displaced. This creates a shockwave that radiates outward from the impact site, causing the surface material to melt, vaporize, and/or fracture. The resulting crater is a bowl-shaped depression that is much larger than the original impactor. The size of the impact crater also depends on the gravity of the target planet or moon. On a planet with stronger gravity, the shockwave generated by an impact will be more concentrated, resulting in a smaller crater for a given impactor sizeIn summary, the size of an impact crater is typically much larger than the size of the impactor that created it, with the exact ratio depending on a number of factors. The size of the impact crater is determined by the amount of energy released during the impact, which causes the target material to be ejected and displaced, resulting in a bowl-shaped depression.

True. An Interactive Voice Response (IVR) system permits a caller to interact with a database of stored information by pressing keys on a telephone pad or speaking words into the phone.
Interactive voice response, or IVR, is an automated telephone system that combines pre-recorded messages or text-to-speech technology with a dual-tone multi-frequency (DTMF) interface to engage callers, allowing them to provide and access information without a live agent. If the IVR system cannot retrieve the information that the caller is looking for, the programmed menu options can provide assistance in routing callers to the appropriate representative for help. By integrating computer and telephony technologies, IVR software can improve call flow and reduce wait times, leading higher overall customer satisfaction.
Moviefone was one of the most famous and successful uses of IVR technology in the 1990s. Since the internet wasn’t as accessible then as it is today, movie-goers would call in and provide their zip code to get a list of available movie theaters near them with their respective movies and show times.

the sustainable growth rate is computed as roe × b when equity used is at the ______ of the period.
Beginning
The sustainable growth rate is computed as ROE × b when equity used is at the "beginning" of the period.
To clarify, the sustainable growth rate is the maximum rate at which a company can grow without using external financing. It is calculated by multiplying the return on equity (ROE) by the retention ratio (b), which is the portion of earnings retained by the company rather than being paid out as dividends. In this calculation, the equity used is considered at the beginning of the period to determine the growth rate.
Growth rates are the percent change of a variable over time. It can be applied to GDP, corporate revenue, or an investment portfolio. Here's how to calculate growth rates. The annual return is the compound average rate of return for a stock, fund, or asset per year over a period of time.
Return on equity (ROE) is a measure of financial performance calculated by dividing net income by shareholders' equity. Because shareholders' equity is equal to a company's assets minus its debt, ROE is considered the return on net assets. The ROE ratio is calculated by dividing the net income of the company by total shareholder equity and is expressed as a percentage. The ratio can be calculated accurately if both net income and equity are positive in value. Return on equity = Net income / average shareholder's equity.
