1. 1An engineer provisions a virtual server through a portal without waiting for a provider employee to process the request. Which essential cloud characteristic does this demonstrate?

   1. A.Resource pooling
   2. B.On-demand self-serviceCorrect answer: B
   3. C.Broad network access
   4. D.Measured service

   Explanation: NIST states, "A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider." The decisive feature is provisioning without human provider interaction. Pooling concerns shared resources, network access concerns connectivity, and metering concerns usage measurement.

2. 2In full virtualization, which component mediates access between guest operating systems and physical computing resources?

   1. A.The guest operating system
   2. B.The host application runtime
   3. C.The virtual machine monitorCorrect answer: C
   4. D.The virtual network interface

   Explanation: The source states, "The guest OSs on a host are managed by the hypervisor, also called the virtual machine monitor (VMM), which controls the flow of instructions between the guest OSs and the physical hardware, such as CPU, disk storage, memory, and network interface cards." The hypervisor, also called the virtual machine monitor, mediates guest instructions and hardware access. A guest OS, application runtime, or network interface does not perform this host-wide mediation.

3. 3A cloud security team reports technical risks separately from business risk decisions. Which executive action best connects cybersecurity governance to enterprise risk management?

   1. A.Delegate enterprise risk acceptance to each cloud vendor.
   2. B.Integrate cybersecurity risks into the organization's ERM program.Correct answer: B
   3. C.Replace enterprise risk reporting with a vulnerability inventory.
   4. D.Evaluate cybersecurity spending only through procurement totals.

   Explanation: The source states, "Executives are also responsible for integrating cybersecurity risk management with ERM programs and lower-level risk management programs (see Sec. 5.2)." Integration makes cybersecurity part of enterprise decision-making. Vendor delegation, technical inventories alone, and procurement totals do not establish that connection.

4. 4An application runs on one large compute resource. The design goal is to reduce the effect of a single resource failure. Which change directly supports that goal?

   1. A.Move all components to a larger resource of the same type.
   2. B.Replace health checks with a scheduled weekly restart.
   3. C.Consolidate dependent components into the same process.
   4. D.Distribute requests across smaller, independent resources.Correct answer: D

   Explanation: The source states, "Replace one large resource with multiple small resources to reduce the impact of a single failure on the overall workload." Independent smaller resources reduce the failure blast radius. Resizing or consolidation retains a single failure point, while scheduled restarts do not distribute the workload.

5. 5A cloud design needs efficient bulk-data protection while allowing separate management of wrapping keys. Why is envelope encryption useful?

   1. A.It improves bulk efficiency by replacing symmetric encryption with public-key encryption.
   2. B.It simplifies access by storing plaintext wrapping keys alongside encrypted messages.
   3. C.It protects data keys by hashing them instead of retaining a decryptable wrapped copy.
   4. D.It combines efficient symmetric encryption with separately managed wrapping keys.Correct answer: D

   Explanation: The source states, "In general, symmetric key algorithms are faster and produce smaller ciphertexts than public key algorithms. But public key algorithms provide inherent separation of roles and easier key management. Envelope encryption lets you combine the strengths of each strategy." The advantage combines efficient symmetric bulk encryption and separate key management. Public-key bulk processing reverses the stated performance advantage; plaintext keys alongside data lose protection, and a hash cannot be unwrapped to recover the data key.

6. 6Logs must remain available but move to a different S3 storage class as they age. Which lifecycle action expresses that requirement?

   1. A.A transition actionCorrect answer: A
   2. B.An expiration action
   3. C.A public-access grant
   4. D.A bucket deletion rule

   Explanation: The source states, "These actions define when objects transition to another storage class." A transition changes storage class. Expiration and deletion remove data, while a public-access grant changes access rather than storage lifecycle.

7. 7An IAM user signs in to AWS with MFA enabled. Which additional element is required beyond the user's credentials?

   1. A.The account alias entered alongside the username
   2. B.The same password entered a second time
   3. C.A response generated by the user's MFA deviceCorrect answer: C
   4. D.The user's access-key identifier without its secret

   Explanation: The source states, "Each user's credentials and device-generated response are required to complete the sign-in process." The device response adds the factor described in the documentation. Account aliases and access-key identifiers are identifiers, while repeating a password does not add a factor.

8. 8Cloud administrators deploy resources using individually chosen settings, with no controlled baseline. Which operational practice directly addresses this weakness?

   1. A.Retain each deployment's settings as its own future baseline.
   2. B.Establish and apply controlled configuration management.Correct answer: B
   3. C.Treat successful provisioning as configuration approval.
   4. D.Copy current settings into records without reconciling drift.

   Explanation: The source states, "Configuration management practices are established and applied" Controlled configuration management supplies the governed baseline. Treating each current state as approved, equating deployment success with approval, or recording drift without reconciliation does not establish that control.

9. 9A business states that its cloud service must be restored within two hours after an interruption. Which recovery objective does this specify?

   1. A.Recovery point objective
   2. B.Maximum backup retention
   3. C.Recovery time objectiveCorrect answer: C
   4. D.Minimum archive duration

   Explanation: The source states, "Recovery Time Objective (RTO) is the maximum acceptable delay between the interruption of service and restoration of service." The statement limits service-restoration delay, which is RTO. RPO concerns the recovery point and potential data loss; retention and archival periods describe how long data is kept.

10. 10A cloud provider stores customer data across jurisdictions. What should the customer's legal review examine before permitting cross-border flows?

    1. A.Apply the provider's headquarters law to every stored copy.
    2. B.Treat the customer's billing address as the sole governing location.
    3. C.Examine data-flow jurisdictions and their continuing obligations.Correct answer: C
    4. D.Assume encryption removes restrictions on cross-border transfers.

    Explanation: The source states, "When information crosses borders, the governing legal, privacy, and regulatory regimes can be ambiguous and raise a variety of concerns (e.g., [CBC04, Wei11])." The actual flow can engage multiple regimes and continuing obligations. Headquarters or billing address alone cannot determine them, and encryption does not by itself remove transfer restrictions.
