SECTION 1: TECHNOLOGY INFRASTRUCTURE, ARCHITECTURE & DESIGN
(QUESTIONS 1 TO 14)
1. An enterprise is migrating from a monolithic architecture to a microservices-based
structure. Which architectural principle should be prioritized to ensure loose coupling and
independent deployability while maintaining data consistency across services?
A. Synchronous RPC communication with centralized transaction managers
B. Event-driven architecture with eventual consistency and domain boundaries
C. Shared database schema with strict referential integrity constraints
D. Centralized message queue with synchronous acknowledgment protocols
Answer: [✓] B.
Explanation: Microservices architecture fundamentally relies on loose coupling and
independent deployability. Event-driven architecture enables asynchronous
communication, reducing direct dependencies between services. Eventual consistency is
acceptable in distributed systems where immediate ACID compliance across services
,would introduce blocking and reduce scalability. Domain boundaries, typically aligned with
business capabilities, ensure that each service owns its data and interfaces. Option A
introduces tight coupling and latency. Option C violates the bounded context principle and
creates a distributed monolith. Option D still enforces synchronous patterns, negating the
benefits of microservices.
2. When designing a resilient cloud infrastructure, which strategy best aligns with the
principle of graceful degradation under partial system failure?
A. Implementing multi-region active-active deployment with synchronous replication
B. Utilizing circuit breakers, fallback mechanisms, and priority-based service routing
C. Deploying redundant load balancers with automatic IP failover
D. Enforcing strict health checks that immediately terminate unhealthy instances
Answer: [✓] B.
Explanation: Graceful degradation ensures that non-critical functions are suspended or
simplified during failures, preserving core functionality. Circuit breakers prevent cascading
failures by halting requests to failing services. Fallback mechanisms provide alternative
responses or cached data. Priority-based routing ensures critical transactions are
processed first. Option A provides high availability but does not inherently manage
degradation; synchronous replication also introduces latency. Option C addresses load
distribution but not application-level resilience. Option D removes capacity but does not
define how remaining services should adapt.
3. A financial institution requires a technology architecture that supports real-time fraud
detection, low-latency transaction processing, and strict regulatory audit trails. Which
design pattern best satisfies these requirements?
A. Lambda architecture with batch and speed layers
B. Kappa architecture with immutable event streams and stream processing
C. Microkernel architecture with plugin-based analytics modules
D. Service-oriented architecture with XML-based web services
Answer: [✓] B.
,Explanation: Kappa architecture treats all data as streams, enabling real-time processing
without maintaining separate batch pipelines. Immutable event streams preserve historical
data for audit compliance and replay capabilities. Stream processing frameworks (e.g.,
Apache Flink, Kafka Streams) support low-latency fraud detection with stateful
computations. Option A requires maintaining two codebases and introduces complexity in
reconciling batch/speed layers. Option C is better suited for extensible application cores,
not high-throughput data pipelines. Option D introduces serialization overhead and lacks
native streaming capabilities.
4. Which infrastructure-as-code (IaC) practice most effectively mitigates configuration drift
in a multi-cloud environment?
A. Manual validation of configuration files before deployment
B. Declarative state management with continuous reconciliation
C. Version-controlled scripts with scheduled manual execution
D. Template-based provisioning with post-deployment audit reports
Answer: [✓] B.
Explanation: Configuration drift occurs when actual infrastructure state diverges from the
intended state. Declarative IaC tools (e.g., Terraform, AWS CloudFormation) define desired
state, and continuous reconciliation automatically detects and corrects drift. This
approach is essential in multi-cloud environments where manual tracking is impractical.
Option A relies on human intervention and is error-prone. Option C still requires manual
execution and lacks automated enforcement. Option D provides visibility but does not
enforce consistency.
5. In a zero-trust network architecture, which mechanism best enforces least-privilege
access for internal services communicating across microsegmented zones?
A. Network access control lists with static IP whitelisting
B. Mutual TLS certificates with dynamic policy enforcement points
C. VLAN segmentation with ACL-based routing rules
D. Firewall rules with stateful packet inspection
Answer: [✓] B.
, Explanation: Zero-trust assumes no implicit trust, even within internal networks. Mutual
TLS (mTLS) provides strong identity verification for both clients and servers. Dynamic policy
enforcement points evaluate contextual signals (device posture, user role, threat
intelligence) before granting access. This aligns with microsegmentation and least
privilege. Option A relies on static IPs, which are easily spoofed and inflexible. Option C
operates at Layer 2/3 and lacks application-layer identity verification. Option D provides
perimeter security but does not enforce continuous verification.
6. Which storage architecture best supports an enterprise requiring high throughput for AI
training workloads, frequent random reads, and cost-efficient archival of raw datasets?
A. Network-attached storage with RAID-6 configuration
B. Tiered object storage with intelligent lifecycle policies
C. Block storage with synchronous cross-site replication
D. Direct-attached storage with hardware RAID controllers
Answer: [✓] B.
Explanation: AI training demands high throughput and parallel access, which object
storage supports via distributed architectures and RESTful APIs. Tiered storage
automatically moves data between hot, warm, and cold tiers based on access patterns,
optimizing cost. Lifecycle policies automate archival without manual intervention. Option
A lacks scalability and parallel access capabilities. Option C is optimized for low-latency
block-level access, not high-throughput analytics. Option D is isolated, difficult to scale,
and lacks automated data movement.
7. A hospital network requires deterministic latency for surgical robotics and high
availability for patient records. Which network design principle should be prioritized?
A. Best-effort routing with QoS tagging
B. Time-sensitive networking (TSN) with priority queuing and redundancy protocols
C. Software-defined WAN with dynamic path optimization
D. Traditional Ethernet with STP and link aggregation
Answer: [✓] B.
