Cloud Architecture and Design practice questions

Cloud Architecture and Design (23% of CV0-004) covers translating business requirements into cloud solutions: high availability and fault tolerance, scaling models, storage and database selection, network topology, and hybrid connectivity. Questions are scenario-based, asking you to pick the architecture or service that satisfies stated constraints such as data residency, multi-AZ resilience, or shared access from on-premises and cloud workloads.

Courseiva uses original exam-style practice questions designed for learning and revision. The goal is to understand the concepts, recognise exam patterns, and improve through explanations — not memorise copied exam dumps.

What the exam tests

What to know about Cloud Architecture and Design

Be able to map requirements like residency, uptime, and shared access to concrete cloud architectures. The single most important thing: eliminate single points of failure with redundancy across zones, and match each storage or scaling choice to the workload's actual access pattern.

Designing multi-AZ and multi-region high availability using load balancers, autoscaling groups, and health checks

Selecting storage types: object, block, and shared file services such as Amazon EFS or Azure Files

Applying data residency, sovereignty, and compliance constraints when choosing regions and replication scope

Choosing scaling approaches: horizontal vs vertical, auto-scaling policies, and PaaS platform scaling features

Watch out for

Common Cloud Architecture and Design exam traps

▸Confusing high availability with disaster recovery: multi-AZ protects against zone failure, but region-wide outages need cross-region replication or failover.
▸Assuming a single VM with a larger instance size provides high availability; vertical scaling still leaves a single point of failure.
▸Treating object storage as a shared POSIX file system for on-premises and cloud VMs, when a managed file service or gateway is required.

A company uses an auto-scaling group to handle variable web traffic. The scaling policy is based on CPU utilization. However, during a flash sale, the application experiences a sudden spike in traffic, and the auto-scaling group takes too long to launch new instances. Which design change would most effectively reduce the time to scale out?

Trap 1: Use larger instance types to handle more traffic

Vertical scaling doesn't improve scaling speed.

Trap 2: Lower the CPU utilization threshold

This triggers scaling earlier but doesn't reduce instance launch time.

Trap 3: Increase the cooldown period

Increasing cooldown delays further scaling actions.

A
Use larger instance types to handle more traffic
Why it fails: Vertical scaling doesn't improve scaling speed.
B
Lower the CPU utilization threshold
Why it fails: This triggers scaling earlier but doesn't reduce instance launch time.
C
Increase the cooldown period
Why it fails: Increasing cooldown delays further scaling actions.
D
Use scheduled scaling to pre-warm instances before the sale
Proactive scaling reduces response time.

Cloud Architecture and Design questions

A company needs to choose a disaster recovery strategy with an RTO of 4 hours and an RPO of 15 minutes. Which of the following is the most cost-effective approach that meets these requirements?

A financial services firm requires low latency between on-premises resources and its public cloud VPC. They also need a dedicated, consistent network connection that bypasses the internet. Which connectivity option should they use?

A cloud architect is designing a multi-region application with a Recovery Time Objective (RTO) of 1 hour and a Recovery Point Objective (RPO) of 15 minutes. The application runs on virtual machines in a public cloud. Which disaster recovery strategy best meets these objectives?

A healthcare organization must store patient imaging data that is accessed infrequently but must be retained for 7 years. They need the lowest-cost storage option while ensuring data can be retrieved within 12 hours if needed. Which storage class should they use?

A cloud architect is designing a solution for a financial analytics application that requires consistent, low-latency block storage for a database. The database will be deployed on a virtual machine in a public cloud. Which TWO storage types are appropriate for this requirement? (Select TWO.)

A cloud architect is designing a cost-optimized architecture for a batch processing workload that runs every hour for 10 minutes. The workload is fault-tolerant and can be interrupted. Which TWO pricing models should the architect consider to minimize costs? (Select TWO.)

A company runs a web application on AWS EC2 instances behind an Application Load Balancer. They want to handle traffic spikes automatically. Which scaling approach should they implement?

A cloud architect is designing a VPC with public and private subnets. Which component is required to allow instances in the private subnet to access the internet for software updates?

A company is deploying a web application that requires high availability across two geographically separate data centers. The application must be active in both sites simultaneously, and traffic must be load-balanced between them. Which architecture best meets these requirements?

A cloud architect is designing a multi-region application on AWS. The application has a critical database that must tolerate the failure of an entire AWS region. Which strategy provides the lowest RTO while ensuring data consistency?

A company wants to migrate a legacy application to the cloud. The application has a monolithic design and requires low-latency access to on-premises databases. The company needs to keep sensitive data on-premises due to regulatory compliance. Which cloud deployment model is most suitable?

A company uses a public cloud IaaS model to host a database. They want to ensure the database remains available if an entire availability zone fails. Which configuration would provide the highest availability with automatic failover?

A company is using AWS and wants to minimize egress costs for data transferred out to the internet. Which strategy would be most effective?
