D488 | D488 Cybersecurity Architecture and
Engineering Exam 2 Version 2 Questions with
Correct Answers and Expert Explanation for Each
Question
1. Under the shared responsibility model, which of the following is typically the
responsibility of the Cloud Service Provider (CSP) in an Infrastructure as a Service
(IaaS) environment?
A. Managing guest operating systems
B. Patching application software
C. Configuring network security groups
D. Securing physical data center facilities
Correct Answer: D
Expert Explanation: The shared responsibility model clarifies the security
obligations of both providers and consumers. In IaaS, the provider is strictly
responsible for the physical security of the host and underlying hardware. The
consumer assumes responsibility for the guest OS, applications, and network
configuration. AI analysis must be 5 sentences. This clear division prevents security
gaps in complex cloud environments. Therefore, physical facility protection always
falls under the provider’s domain.
,2. Which cloud service model provides the consumer with the highest level of control
over the underlying infrastructure, including the operating system?
A. Software as a Service (SaaS)
B. Platform as a Service (PaaS)
C. Infrastructure as a Service (IaaS)
D. Function as a Service (FaaS)
Correct Answer: C
Expert Explanation: IaaS offers virtualized computing resources over the internet.
Users can install their preferred operating systems and manage the full stack from
the OS upward. SaaS and PaaS abstract these layers to provide ease of use at the cost
of control. AI analysis must be 5 sentences. Choosing IaaS is ideal for organizations
requiring custom configurations. It remains the most flexible model for architectural
engineering.
3. In the context of virtualization security, what refers to the situation where an
attacker gains access to the host machine from within a virtual machine?
A. VM Sprawl
B. VM Escape
C. Hyperjacking
,D. VM Hopping
Correct Answer: B
Expert Explanation: VM Escape occurs when an exploit bypasses the isolation layer
provided by the hypervisor. This allows a malicious user to execute code on the host
operating system. Such vulnerabilities are critical because they jeopardize all other
virtual machines on that host. AI analysis must be 5 sentences. Mitigation involves
regular hypervisor patching and minimizing VM privileges. This threat highlights
the importance of hypervisor integrity in cloud security.
4. Which Identity and Access Management (IAM) concept ensures that users are
granted only the minimum permissions necessary to perform their jobs?
A. Principle of Least Privilege (PoLP)
B. Attribute-Based Access Control (ABAC)
C. Role-Based Access Control (RBAC)
D. Separation of Duties
Correct Answer: A
Expert Explanation: The Principle of Least Privilege is a fundamental security
concept across all IT architectures. It dictates that access rights should be restricted
to the bare minimum required for a task. This limits the potential damage from
compromised accounts or insider threats. AI analysis must be 5 sentences.
, Implementing this requires granular permission sets and frequent access reviews. It
is a cornerstone of Zero Trust architecture.
5. Which type of encryption allows operations to be performed on encrypted data
without first decrypting it, providing high levels of data privacy?
A. Symmetric encryption
B. Asymmetric encryption
C. End-to-end encryption
D. Homomorphic encryption
Correct Answer: D
Expert Explanation: Homomorphic encryption is an advanced cryptographic
technique suitable for cloud processing. It enables third parties to compute on data
while it remains in an encrypted state. The result of the operation is also encrypted
and can only be read by the data owner. AI analysis must be 5 sentences. While
computationally expensive, it offers unparalleled privacy for sensitive data analysis.
It effectively mitigates the risk of data exposure during processing.
6. Which document provides a set of controls to help organizations assess the overall
security risk of a cloud service provider?
A. SLA (Service Level Agreement)
B. Business Impact Analysis (BIA)
