SECTION 1: CLOUD ARCHITECTURE (23%)
Question 1
A multinational corporation is designing a cloud architecture that must maintain operations
during a regional disaster while ensuring sub-second failover for mission-critical applications.
The architecture must also support geographic data residency requirements. Which
combination of strategies BEST meets these requirements?
A. Single-region deployment with synchronous replication and active-passive failover
B. Multi-region active-active deployment with global load balancing and asynchronous
replication
C. Multi-region active-active deployment with global load balancing and synchronous replication
D. Single-region deployment with asynchronous replication and active-active configuration
-” detailed answer 100 % correct :-”C
Rationale: Multi-region active-active deployment with global load balancing provides
immediate failover (sub-second) and geographic distribution. Synchronous replication ensures
zero data loss (RPO=0) between regions, though it introduces latency considerations. Active-
active allows both regions to serve traffic, maximizing availability.
Question 2
A cloud architect is evaluating storage options for a big data analytics platform that processes
petabytes of unstructured data. The data is accessed infrequently but must be retrievable
within minutes when needed. Cost optimization is a primary concern. Which storage tier is
MOST appropriate?
A. Hot tier with SSD storage
B. Cold tier with object storage
C. Archive tier with tape backup
D. Warm tier with standard object storage
-” detailed answer 100 % correct :-”B
Rationale: Cold tier object storage is designed for infrequently accessed data with retrieval
times in minutes, offering significant cost savings compared to hot storage. Archive tier retrieval
times are typically hours, not minutes.

Question 3
Which of the following cloud service models places the GREATEST management responsibility
on the customer while providing the highest level of control?
A. Software as a Service (SaaS)
B. Platform as a Service (PaaS)
C. Infrastructure as a Service (IaaS)
D. Function as a Service (FaaS)
-” detailed answer 100 % correct :-”C
Rationale: IaaS provides the customer with the most control over the infrastructure (OS,
applications, middleware) while the provider manages only the underlying physical hardware.
This shifts maximum management responsibility to the customer.
Question 4
A company is deploying a web application that experiences highly variable traffic patterns, with
sudden spikes during flash sales. The application must scale automatically without manual
intervention. Which cloud characteristic directly enables this capability?
A. Measured service
B. Resource pooling
C. Rapid elasticity
D. Broad network access
-” detailed answer 100 % correct :-”C
Rationale: Rapid elasticity enables automatic scaling of resources up or down based on
demand. This is the cloud characteristic that allows systems to handle traffic spikes without
manual provisioning.
Question 5
An organization is implementing a hybrid cloud strategy. Which of the following is the MOST
significant challenge they must address?
A. Increased capital expenditure
B. Limited geographic reach
C. Network latency and connectivity between environments
D. Reduced security controls
, 4
-” detailed answer 100 % correct :-”C
Rationale: Hybrid cloud environments require secure, reliable, and low-latency connectivity
between on-premises and cloud resources. Network latency and connectivity challenges are the
most significant technical hurdle in hybrid deployments.
Question 6
A cloud engineer is designing a highly available web application that must withstand the failure
of an entire availability zone. Which architecture BEST achieves this objective?
A. Deploy all application components within a single availability zone with redundant instances
B. Deploy application components across multiple availability zones within the same region
C. Deploy application components across multiple regions with active-passive failover
D. Deploy application components on a single instance with automated backup
-” detailed answer 100 % correct :-”B
Rationale: Deploying across multiple Availability Zones (AZs) within the same region provides
protection against AZ failures while maintaining low latency between components. This is the
standard approach for high availability in cloud architectures.
Question 7
Which virtualization technology provides the HIGHEST level of isolation between workloads
while sharing the same physical hardware?
A. Containerization
B. Paravirtualization
C. Full hardware virtualization
D. OS-level virtualization
-” detailed answer 100 % correct :-”C
Rationale: Full hardware virtualization (Type 1 hypervisor) provides the strongest isolation
because each VM runs its own complete OS kernel with hardware-level separation. Containers
share the host OS kernel, offering less isolation.
Question 8
A cloud architect is designing a solution that must support legacy applications that cannot be
