Sample Questions (10 of 100 shown)

Q1 Cloud Architecture (13%)
A company wants to maintain complete control over their physical infrastructure while still benefiting from cloud-like resource pooling and self-service capabilities. Which cloud deployment model best meets these requirements?
  1. Public cloud
  2. Private cloud
  3. Hybrid cloud
  4. Community cloud
✓ Correct Answer: B
A private cloud is a cloud deployment model where infrastructure is provisioned for exclusive use by a single organization. It can be owned, managed, and operated by the organization, a third party, or a combination, and may exist on-premises or off-premises. This model provides complete control over physical infrastructure while still offering cloud characteristics such as resource pooling, rapid elasticity, and self-service. Public cloud shares infrastructure across multiple organizations, hybrid combines public and private, and community cloud shares among specific organizations with common concerns.
Q2 Cloud Architecture (13%)
Which cloud characteristic enables customers to provision computing resources automatically without requiring human interaction with service providers?
  1. Broad network access
  2. Resource pooling
  3. Rapid elasticity
  4. On-demand self-service
✓ Correct Answer: D
On-demand self-service is a fundamental cloud characteristic that allows consumers to unilaterally provision computing capabilities (such as server time and network storage) as needed automatically, without requiring human interaction with each service provider. Broad network access refers to capabilities being available over the network. Resource pooling enables multi-tenant models. Rapid elasticity allows resources to be elastically provisioned and released.
Q3 Cloud Architecture (13%)
A manufacturing company is modernizing its supply chain application by using a best-in-class machine learning service from one public cloud provider and a specialized IoT data ingestion service from a different public cloud provider. Which cloud model does this strategy represent?
  1. Community
  2. Private
  3. Multi-cloud
  4. Hybrid
✓ Correct Answer: C
Multi-cloud refers to the use of cloud services from two or more public cloud providers simultaneously. In this scenario, the company is using a machine learning service from one public cloud provider and an IoT service from another — a classic multi-cloud strategy that allows organizations to select best-of-breed services from different vendors. Hybrid cloud combines public and private cloud. Community cloud is shared among a specific community. Private cloud is for a single organization.
Q4 Cloud Architecture (13%)
A company is designing a multi-tenant SaaS application. They need to ensure that one tenant's database queries cannot impact the performance of other tenants. Which architectural pattern should they implement?
  1. Shared database, shared schema with row-level security
  2. Shared database, separate schemas per tenant
  3. Separate databases per tenant with resource quotas
  4. Database sharding based on tenant ID
✓ Correct Answer: C
Separate databases per tenant with resource quotas provide the strongest performance isolation. Each tenant gets their own database instance with allocated resources (CPU, memory, I/O), preventing one tenant's queries from affecting others. While more expensive than shared approaches, it satisfies strict performance isolation requirements. Shared database approaches carry risk of performance interference, and sharding alone does not provide resource isolation.
Q5 Cloud Architecture (13%)
In a Type 1 hypervisor (bare-metal hypervisor), which component runs directly on the host hardware?
  1. The host operating system
  2. The hypervisor itself
  3. The guest operating systems
  4. A virtualization management layer
✓ Correct Answer: B
In a Type 1 (bare-metal) hypervisor, the hypervisor runs directly on the host hardware without an intermediary host operating system. Examples include VMware ESXi, Microsoft Hyper-V, and Xen. This architecture provides better performance and security compared to Type 2 hypervisors, which run on top of a host operating system. Guest operating systems run on top of the hypervisor, not directly on the hardware.
Q6 Cloud Architecture (13%)
An organization is migrating legacy applications to the cloud and wants to minimize changes to existing code while gaining cloud benefits. Which cloud service model would be MOST appropriate?
  1. Software as a Service (SaaS)
  2. Platform as a Service (PaaS)
  3. Infrastructure as a Service (IaaS)
  4. Function as a Service (FaaS)
✓ Correct Answer: C
IaaS provides the greatest flexibility by offering virtual machines where organizations can deploy their existing applications with minimal or no code changes. The legacy application can run on cloud VMs just as it did on-premises, while gaining benefits like elasticity, pay-as-you-go pricing, and managed infrastructure. PaaS and FaaS typically require application modifications to fit platform constraints. SaaS is a complete software solution where the customer does not manage any infrastructure.
Q7 Cloud Architecture (13%)
A company needs to deploy its own code directly in the cloud without provisioning additional infrastructure. Which of the following is the best cloud service model for the company to use?
  1. PaaS
  2. SaaS
  3. IaaS
  4. XaaS
✓ Correct Answer: A
Platform as a Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure. Developers can deploy their code directly to the platform, which handles provisioning, scaling, and managing the underlying servers, storage, and networking. SaaS delivers ready-to-use software. IaaS requires the customer to manage the OS and middleware. XaaS is a generic term for "anything as a service."
Q8 Cloud Architecture (13%)
When presenting the case for a multi-cloud strategy to company leadership, a cloud architect emphasizes the ability to select services from different vendors based on features and pricing. What are two key advantages of this approach? (Choose Two)
  1. Lowered requirement for specialized staff skills
  2. Unified billing and financial reporting
  3. Reduced risk of vendor lock-in
  4. Simplified security and compliance management
  5. Access to best-of-breed services from different providers
✓ Correct Answer: C, E
Multi-cloud strategies offer two primary advantages: reduced vendor lock-in (by not being dependent on a single provider's proprietary services and pricing) and access to best-of-breed services (choosing the optimal service from each provider based on features, performance, or cost). The other options are actually disadvantages — multi-cloud typically increases staffing complexity, billing fragmentation, and security/compliance management challenges.
Q9 Cloud Architecture (13%)
A cloud engineer is designing a microservices architecture for a cloud-native application. The architecture requires service discovery, load balancing, and automated scaling. Which combination of technologies would BEST support this requirement?
  1. Container orchestration platform with service mesh and horizontal pod autoscaler
  2. Virtual machines with manual DNS configuration and round-robin load balancing
  3. Monolithic application with vertical scaling and hardware load balancer
  4. Serverless functions with API gateway and manual instance management
✓ Correct Answer: A
A container orchestration platform (like Kubernetes) combined with a service mesh (like Istio or Linkerd) and horizontal pod autoscaler (HPA) provides all required capabilities natively: service discovery via built-in DNS, load balancing via the service mesh, and automated scaling via HPA based on CPU/memory or custom metrics. Virtual machines with manual configuration lack automation. Monolithic architecture contradicts microservices requirements. Serverless with manual management defeats the purpose of automation.
Q10 Cloud Architecture (13%)
Which storage type is best suited for a cloud-based application requiring high IOPS for a database workload with random access patterns?
  1. Object storage (S3-compatible)
  2. File storage (NFS)
  3. Block storage with SSD backing
  4. Cold archival storage
✓ Correct Answer: C
Block storage with SSD backing provides the highest IOPS and lowest latency for database workloads with random access patterns. Block storage presents raw block devices to the OS, allowing the database to manage its own filesystem and I/O patterns optimally. Object storage has higher latency and is better for unstructured data. File storage adds protocol overhead and is designed for shared access. Cold archival storage is for infrequent access, not high-performance scenarios.
