CCSP Cloud Concepts, Architecture and Design — Timed 20 Questions

Question 1

A healthcare organization is migrating sensitive patient data to a public cloud. The compliance team requires that data be encrypted at rest and in transit, and that the cloud provider cannot access the encryption keys. Which cloud service model should the organization use to maintain sole control over encryption keys?

Accepted Answer

Infrastructure as a Service (IaaS). IaaS provides the customer with full control over the underlying infrastructure, including virtual machines, storage, and networking. This allows the organization to implement their own encryption mechanisms and manage their own keys using a Hardware Security Module (HSM) or a key management service (KMS) that the cloud provider cannot access. In contrast, SaaS and PaaS typically abstract away the infrastructure, limiting customer control over encryption key management.

Answer

Software as a Service (SaaS)

Answer

Hybrid Cloud

Answer

Platform as a Service (PaaS)

Question 2

A company is designing a multi-tier application in the cloud. The web tier must automatically scale based on CPU utilization, while the database tier should remain fixed to maintain data consistency. Which architectural pattern best meets these requirements?

Accepted Answer

Horizontal auto-scaling for the web tier and a fixed database tier. Option A is correct because it separates the stateless web tier, which can safely scale horizontally using auto-scaling groups triggered by CPU utilization thresholds, from the stateful database tier, which must remain fixed to avoid consistency issues such as split-brain or replication lag. Horizontal scaling adds or removes identical web server instances without affecting session state, while a fixed database tier preserves ACID properties and prevents conflicts from concurrent writes across multiple database nodes.

Answer

Manual scaling for both tiers

Answer

Vertical scaling of all tiers

Answer

Single-tier architecture with auto-scaling

Question 3

A financial services firm is designing a cloud environment that must comply with PCI DSS. The security architect proposes using a virtual private cloud (VPC) with subnets, security groups, and network ACLs. However, the compliance officer is concerned about the risk of data exposure due to misconfiguration. Which additional control would BEST address this concern?

Accepted Answer

Integrate Cloud Security Posture Management (CSPM). CSPM tools continuously monitor cloud infrastructure configurations against compliance frameworks like PCI DSS, automatically detecting misconfigurations such as overly permissive security group rules or network ACLs that could expose cardholder data. This directly addresses the compliance officer's concern about data exposure due to misconfiguration by providing real-time visibility and remediation guidance, which is more proactive than the other options.

Answer

Use a Web Application Firewall (WAF)

Answer

Implement a Security Information and Event Management (SIEM) system

Answer

Deploy Data Loss Prevention (DLP) tools

Question 4

A cloud architect is tasked with designing a disaster recovery plan for a critical application. The recovery time objective (RTO) is 1 hour, and the recovery point objective (RPO) is 15 minutes. The application runs on IaaS with data stored in a relational database. Which replication strategy is MOST cost-effective while meeting the objectives?

Accepted Answer

Asynchronous storage-level replication with 15-minute snapshots. Option D is correct because asynchronous storage-level replication with 15-minute snapshots meets the RPO of 15 minutes and the RTO of 1 hour, while being more cost-effective than synchronous replication. Asynchronous replication avoids the latency and bandwidth costs of synchronous mirroring across regions, and the 15-minute snapshot schedule ensures data loss is limited to the RPO window. This strategy is suitable for IaaS relational databases where near-real-time consistency is acceptable.

Answer

Daily full backups to another region

Answer

Synchronous database mirroring across regions

Answer

Multi-region active-active deployment with load balancing

Question 5

Which THREE of the following are key characteristics of cloud computing as defined by NIST SP 800-145?

Accepted Answer

Broad network access. Option A is correct because NIST SP 800-145 defines broad network access as the capability for cloud capabilities to be accessed over the network by standard mechanisms (e.g., HTTPS, SSH, VPN) that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, workstations). This characteristic ensures that resources are available from any location with internet connectivity, not limited to a single physical network segment.

Answer

Location independence

Answer

Dedicated hardware per tenant

Question 6

Refer to the exhibit. A security engineer is reviewing this S3 bucket policy. The bucket contains sensitive documents that should only be accessible from the internal network (10.0.0.0/24) and only over HTTPS. What is the most likely effect of this policy?

Accepted Answer

The policy allows GetObject from the internal network only when using HTTPS.. The policy includes an explicit Deny for any request that does not use HTTPS (i.e., aws:SecureTransport is false), which overrides any Allow. The Allow statement grants s3:GetObject only when the source IP is within 10.0.0.0/24. Therefore, the effective result is that GetObject is allowed only from the internal network and only over HTTPS, making option B correct.

Answer

The policy allows access from any IP if the request uses HTTPS.

Answer

The policy allows access from any IP in 10.0.0.0/24, but blocks access from the VPC.

Answer

The policy denies all access to the bucket because of the explicit Deny statement.

Question 7

Your company, a global e-commerce platform, operates on a multi-cloud environment with workloads in AWS and Azure. You are the lead cloud architect. The platform experiences peak traffic during promotional events, with traffic spikes up to 10x normal. The application is composed of microservices running in containers orchestrated by Kubernetes on both clouds. Each cloud provider's Kubernetes cluster uses cluster autoscaler and horizontal pod autoscaler. Recently, during a flash sale, the AWS cluster failed to scale adequately, causing latency spikes and timeouts. AWS support indicated that the cluster hit a service quota limit for EC2 instances. You need to prevent this from recurring. You have the following options: A) Implement a multi-region deployment on AWS to distribute load. B) Pre-warm the AWS environment by requesting a service quota increase and using a pod priority class to ensure critical pods scale first. C) Migrate all workloads to Azure to simplify management. D) Use a global load balancer to route traffic to the cloud with the most available capacity. Which option is the best course of action?

Accepted Answer

Pre-warm the AWS environment by requesting a service quota increase and using a pod priority class to ensure critical pods scale first.. Option D is correct because the root cause is a hard AWS service quota for EC2 instances, which prevents the cluster autoscaler from launching new nodes. Requesting a quota increase removes this bottleneck, while pod priority classes ensure that critical microservices are scheduled first when resources are constrained, preventing latency spikes during flash sales.

Answer

Migrate all workloads to Azure to simplify management.

Answer

Use a global load balancer to route traffic to the cloud with the most available capacity.

Answer

Implement a multi-region deployment on AWS to distribute load.

Question 8

Drag and drop the steps for performing a cloud migration using the 'lift and shift' strategy into the correct order.

Question 9

Drag and drop the steps for implementing a data retention policy for cloud storage (e.g., Amazon S3) into the correct order.

Question 10

Match each NIST SP 800-53 control family to its focus area.

Question 11

Match each cloud auditing term to its definition.

Question 12

A company is migrating to the cloud to reduce capital expenditures. They want to pay only for the resources they consume with no upfront investment. Which financial model does this describe?

Accepted Answer

Opex. Option D is correct because the operating expenditure (Opex) model allows a company to pay for cloud resources on a consumption basis without any upfront capital investment. This aligns with the goal of reducing capital expenditures (Capex) by shifting costs to variable, pay-as-you-go operational expenses.

Answer

Amortization

Answer

Capex

Answer

Leasing

Question 13

A healthcare provider is subject to HIPAA regulations. They are planning to use a public cloud provider. Which design consideration is most important to ensure compliance?

Accepted Answer

Data residency. Data residency is the most critical design consideration for a healthcare provider subject to HIPAA when using a public cloud, because HIPAA requires that protected health information (PHI) be stored and processed only in jurisdictions where the cloud provider can guarantee compliance with the HIPAA Privacy and Security Rules. If the cloud provider replicates data across regions or countries without explicit control, the organization may violate the HIPAA requirement to ensure that PHI is not exposed to unauthorized access or disclosure, and may also breach the Breach Notification Rule if data crosses borders into regions with weaker protections.

Answer

Containerization

Answer

Cost optimization

Answer

Multi-cloud strategy

Question 14

An organization is designing a cloud application that must remain available even if an entire AWS availability zone fails. Which architecture pattern should they implement?

Accepted Answer

Single region with multiple AZs active-active. The correct architecture is a single region with multiple Availability Zones (AZs) in an active-active configuration. This ensures that if one AZ fails, the application continues to serve traffic from the remaining AZs without any manual intervention, as all AZs are actively handling requests. AWS Availability Zones are physically separate data centers within a region, and an active-active pattern distributes the workload across them to achieve high availability and fault tolerance.

Answer

Single region with multiple AZs active-standby

Answer

Active-passive in a single region

Answer

Multi-region active-active

Question 15

A company wants to ensure that their cloud deployment has the highest level of isolation between tenants. Which deployment model is most appropriate?

Accepted Answer

Private cloud. Private cloud (Option C) is correct because it is a single-tenant environment where the cloud infrastructure is dedicated exclusively to one organization, providing the highest level of isolation between tenants. In a private cloud, network segmentation is achieved through technologies such as VLANs (IEEE 802.1Q), VXLANs (RFC 7348), and dedicated hypervisor-level resource pools, ensuring that no other tenant's workloads share the same physical or virtual resources. This eliminates the multi-tenancy risks inherent in public and community clouds, where isolation relies on shared infrastructure and logical separation mechanisms like hypervisor-enforced memory isolation and network overlays.

Answer

Public cloud

Answer

Hybrid cloud

Answer

Community cloud

Question 16

A developer is designing a microservices-based application in the cloud. They need to ensure communication between services is loosely coupled and resilient to failures. Which design pattern should they implement?

Accepted Answer

Event-driven messaging. Event-driven messaging (B) is correct because it enables asynchronous, decoupled communication between microservices, allowing them to operate independently and remain resilient to failures. When a service publishes an event, other services consume it at their own pace, preventing cascading failures and ensuring the system can handle partial outages without blocking. This pattern directly supports loose coupling and fault tolerance, which are critical for cloud-based microservices architectures.

Answer

API gateway

Answer

Service mesh

Answer

Database per service

Question 17

An auditor is reviewing a cloud provider's SOC 2 Type II report. Which aspect of the report is most relevant for assessing the effectiveness of controls over a period?

Accepted Answer

Description of tests and results. The SOC 2 Type II report evaluates the operational effectiveness of controls over a specified period (typically 6–12 months). The 'Description of tests and results' section provides the auditor's detailed testing procedures and outcomes, directly showing whether controls operated effectively throughout that period. This makes it the most relevant aspect for assessing control effectiveness over time.

Answer

System description

Management's assertion

Question 18

A cloud architect is designing a disaster recovery plan for a financial application with RTO of 15 minutes and RPO of 5 minutes. Which recovery strategy is most appropriate?

Accepted Answer

Multi-region active-active. Multi-region active-active is the only strategy that can meet both a 15-minute RTO and a 5-minute RPO because it maintains synchronous or near-synchronous replication between two or more regions, allowing traffic to be instantly redirected with zero or minimal data loss. This approach eliminates the recovery time needed to spin up infrastructure or restore data, as the application is already fully operational in multiple regions.

Answer

Backup and restore

Answer

Pilot light

Answer

Warm standby

Question 19

A small business wants to use a cloud service but has limited in-house IT expertise. Which cloud service model requires the least customer management responsibility?

Accepted Answer

SaaS. SaaS (Software as a Service) delivers a complete application managed entirely by the cloud provider, so the customer only needs to use the software without managing underlying infrastructure, platforms, or runtime. For a small business with limited IT expertise, this model minimizes operational overhead because the provider handles maintenance, patching, and availability.

Answer

IaaS

Answer

PaaS

Answer

FaaS

Question 20

During a cloud migration, a company decides to move a legacy application with no code changes. Which migration strategy are they using?

Accepted Answer
