Rapid elasticity is the cloud computing characteristic that allows consumers to automatically expand or contract resources based on demand. Managing Cloud documentation explains that rapid elasticity enables scaling of computing resources in near real time.

This capability allows organizations to handle variable workloads efficiently without manual intervention. Resources can be provisioned when demand increases and released when demand decreases, optimizing performance and cost.

Measured service focuses on usage tracking, resource pooling shares infrastructure, and on-demand self-service enables user provisioning. Therefore, rapid elasticity is the correct answer.

The Health Insurance Portability and Accountability Act (HIPAA) defines requirements for the electronic transfer of healthcare data to a cloud service provider. Managing Cloud documentation explains that HIPAA governs the protection, transmission, and storage of protected health information (PHI).

HIPAA establishes administrative, technical, and physical safeguards to ensure confidentiality, integrity, and availability of healthcare data. When healthcare organizations use cloud services, both the organization and the cloud provider must ensure compliance with HIPAA requirements.

The other regulations do not apply to healthcare data transfer. Stark Law addresses physician self-referral, the Healthcare Quality Improvement Law focuses on peer review, and GLBA applies to financial institutions. Therefore, HIPAA is the correct answer.

In the Infrastructure as a Service (IaaS) model, the cloud consumer is responsible for installing and maintaining the operating system. Managing Cloud principles describe that IaaS provides virtualized computing resources such as servers, storage, and networking, while leaving system-level management to the customer.

Customers must install operating systems, apply patches, configure security settings, and manage applications running on the infrastructure. This responsibility provides flexibility but also requires strong operational and security controls.

In PaaS and SaaS, the provider manages the operating system. NaaS focuses on network services rather than OS management. Therefore, IaaS is the correct answer.

A Web Application Firewall (WAF) includes anti-distributed denial of service (DDoS) capabilities designed to protect cloud-hosted applications and underlying data storage from availability-based attacks. Managing Cloud principles state that WAFs sit in front of web applications and analyze incoming traffic to identify and block malicious requests, including high-volume attack patterns characteristic of DDoS attacks.

By filtering traffic at the application layer, a WAF prevents excessive or malicious requests from overwhelming backend services such as cloud storage systems and databases. Many WAF solutions implement rate limiting, traffic profiling, and behavioral analysis to distinguish legitimate users from attackers, ensuring continued access to cloud resources.

The other options do not provide DDoS protection. An XML gateway focuses on validating and securing XML-based messages. NDAM and ADAM solutions monitor database activity but do not mitigate network-level or application-layer flood attacks. Therefore, the Web Application Firewall is the correct security device for providing anti-DDoS protection in cloud environments.

The capability to rapidly create and destroy virtual systems as demand fluctuates is known as ephemeral computing. These short-lived resources are provisioned automatically when needed and decommissioned when demand subsides.

Resource scheduling helps allocate resources but does not imply temporary lifespans. High availability ensures continuous service, and maintenance mode is used for administrative tasks.

Ephemeral computing is central to elasticity in cloud environments, reducing costs and improving scalability. For example, containers or serverless functions may run only while needed and then disappear. This model optimizes utilization, lowers expenses, and supports modern application architectures that demand agility.

Cloud providers typically manage multi-tenant infrastructure, where physical hardware is shared among customers. Therefore, drives are not destroyed for each customer unless explicitly required in the contract. If the customer’s agreement specifies dedicated hardware disposal, then the provider must comply by physically destroying the drives.

Cryptographic erasure and degaussing are valid sanitization methods, but they may not meet the specific contractual requirement of physical destruction. Insurance clauses are unrelated to disposal.

This question underscores the importance of negotiating contractual terms in cloud agreements. Customers handling highly sensitive or regulated data may require physical destruction, while others may accept logical erasure. Clear agreements ensure both compliance and alignment of security responsibilities.

Service level agreement (SLA) penalties are a risk mitigation technique that compensates customers for failures by the cloud service provider. Managing Cloud principles explain that SLAs define performance commitments such as availability, response time, and reliability.

When a provider fails to meet these commitments, SLA penalties—often in the form of service credits or financial compensation—are applied. While penalties do not prevent failures, they provide accountability and partial financial remediation.

Recovery time objectives define recovery goals, data protection requirements address security controls, and suspension clauses govern service termination. None of these compensate customers directly. Therefore, SLA penalties are the correct mitigation technique.

UESTION NO: 121 [Conducts Risk Management]

Which risk is assumed by an enterprise that chooses to use vendor-provided cloud resources?

A. Incompatible infrastructure

B. Multitenant deployments

C. Lack of skilled technical personnel

D. Loss of certification

Answer: B

By choosing vendor-provided cloud resources, an enterprise inherently assumes the risk associated with multitenant deployments. Managing Cloud principles explain that public and some community cloud environments are built on shared infrastructure where multiple customers’ workloads coexist on the same physical hardware.

Although strong logical isolation mechanisms are implemented by cloud providers, multitenancy introduces risks such as data leakage, side-channel attacks, and resource contention. These risks do not exist to the same degree in dedicated on-premises environments. Enterprises must therefore rely on the provider’s ability to enforce isolation, access control, and monitoring.

The other options are not intrinsic cloud risks. Incompatible infrastructure can be addressed through architecture design, lack of skilled personnel is an internal organizational issue, and loss of certification relates to compliance management. Therefore, multitenant deployments represent the risk assumed when using vendor-provided cloud resources.

Offsite backups are an effective countermeasure against vendor lock-in and lock-out risks. Managing Cloud principles explain that maintaining copies of data outside a single cloud provider reduces dependency and ensures continued access if services become unavailable.

Offsite backups enable organizations to migrate data, recover from provider outages, or exit a provider relationship without losing critical information. This control supports business continuity, portability, and resilience.

Video surveillance addresses physical security, disk redundancy improves availability within the same provider, and training programs improve awareness but do not reduce dependency. Therefore, offsite backups are the correct security control.
