CISA QUESTION #6833

Question 6

An auditor reviews a service level agreement between an organization and its cloud service provider. The SLA contains detailed uptime guarantees but no provisions for data ownership, data destruction procedures, or right to audit. What is the MOST significant omission?

Incomplete performance metrics
Lack of data governance and audit rights creates unmanageable risk✔️
Insufficient technical specifications
Limited scope

Correct Answer Logic:

While uptime is important, fundamental issues of data ownership, secure data destruction, and audit rights are critical for risk management and compliance. Without these provisions, the organization cannot verify security controls, ensure data is properly destroyed when the relationship ends, or establish clear ownership rights.

Pharmacokinetics and Pharmacodynamics QUESTION #3846

Question 11

Which of the following characteristics is a defining feature of drugs exhibiting non-linear (saturable) pharmacokinetics?

A constant ratio of drug metabolites is formed as the administered dose increases
The elimination half-life increases as the administered dose is increased✔️
The area under the curve (AUC) increases in direct proportion to an increase in the administered dose
The steady-state drug concentration increases in direct proportion to the dosing rate

Correct Answer Logic:

In non-linear pharmacokinetics, metabolic enzymes become saturated at higher doses. This leads to disproportionately longer half-lives, higher AUC, and unpredictable dose–concentration relationships.
