English QUESTION #11592

having
with✔️
of
None of these

Correct Answer Logic:

The correct preposition here is with. We use “with” to indicate a feature or attribute something possesses — e.g., “a car with a sunroof.” While “having” is grammatically possible in some contexts, “with” is the idiomatic and natural choice when describing a characteristic of a noun. “Of” would imply origin or composition, which is incorrect here.

Correct Answer: B — with.

Verbal Reasoning QUESTION #8109

Question 183

Which of the following is a solution to $x + x^2 = 1$?

$-1$
$0$
$\dfrac{1}{2}$
None of the above✔️

Correct Answer Logic:

Test each option in $x + x^2 = 1$:

$x = -1$: $(-1) + (-1)^2 = -1 + 1 = 0 \neq 1$
$x = 0$: $0 + 0 = 0 \neq 1$
$x = \dfrac{1}{2}$: $\dfrac{1}{2} + \dfrac{1}{4} = \dfrac{3}{4} \neq 1$
$x = 1$: $1 + 1 = 2 \neq 1$

Solving $x^2 + x - 1 = 0$: $x = \dfrac{-1 \pm \sqrt{5}}{2}$, which gives irrational values not among the standard choices. Therefore, none of the listed options is a solution.

Question 184

Which is larger: $\frac{3}{5}$ or $\frac{5}{8}$?

$\frac{3}{5}$
$\frac{5}{8}$✔️
Equal
Cannot compare

Correct Answer Logic:

Convert: $\frac{3}{5} = 0.6$ and $\frac{5}{8} = 0.625$. Since $0.625 > 0.6$, $\frac{5}{8}$ is larger.

CISA QUESTION #6846

Question 196

An IS auditor discovers that security logs are generated but retained for only 7 days due to storage limitations. The organization's incident response procedures require 90 days of log data for investigation. What is the PRIMARY risk?

Inadequate storage capacity
Insufficient log retention prevents effective incident investigation and forensic analysis✔️
Excessive log volume
Complex log management

Correct Answer Logic:

The 83-day gap between log retention (7 days) and investigative requirements (90 days) means most incidents cannot be properly investigated. By the time incidents are detected and investigation begins, critical evidence has been deleted. This severely compromises security monitoring, incident response, and forensic capabilities.
