Explanation: A reservation will not guarantee auto-scaling is available because it involves the allocation of additional resources beyond what a cloud customer already has provisioned. Reservations will guarantee minimal resources are available to start virtual machines, run applications, and perform normal business operations.

Explanation: Potential clients are not served by SOC Type 1 audits. A Type 2 or Type 3 report would be appropriate for potential clients. SOC Type 1 reports are intended for restricted use, where only the service organization itself, current clients, or auditors would have access to them.

Explanation: The official categories of cloud risk ratings are Minimal, Low, Moderate, High, and Critical.

Explanation: A retina scan could be used in conjunction with an RSA token because it is a biometric factor, and thus a different type of factor. An access card, RFID, and USB thumb drive are all items in possession of a user, the same as an RSA token, and as such would not be appropriate.

Explanation: Application virtualization is a software implementation that allows applications and programs to run in an isolated environment rather than directly interacting with the operating system. Sandboxing refers to segregating information or processes for security or testing purposes, but it’s not directly related to isolation from the underlying operating system. Abstracting sounds similar to the correct term but is not pertinent to the question, and hosting is provided as an erroneous answer.

Explanation: The zeroing of data–or the writing of null values or arbitrary data to ensure deletion has been fully completed–is officially referred to as overwriting. Nullification, deleting, and blanking are provided as distractor terms.

Explanation: The FIPS 140-2 standard pertains to the certification of cryptographic modules and is not a regulatory framework. The Payment Card Industry Data Security Standard (PCI DSS), the Federal Risk and Authorization Management Program (FedRAMP), and the Health Insurance Portability and Accountability Act (HIPAA) are all regulatory frameworks for sensitive or specialized data.

Explanation: Multifactor authentication systems are composed of something the user knows, has, and/or is, not something the user sends. Multifactor authentication commonly uses something that a user knows, has, and/or is (such as biometrics or features).

Explanation: BCDR planning tends to focus so much on the failing over of services in the case of a disaster that recovery back to primary hosting after the disaster is often overlooked. In many instances, this can be just as complex a process as failing over, if not more so. Availability of staff, capacity at the BCDR site, and change management processes are typically integral to BCDR plans and are common components of them.

Explanation: Tokenization involves the replacement of sensitive data fields with key or token values, which can ultimately be mapped back to the original, sensitive data values. Masking refers to the overall approach to covering sensitive data, and anonymization is a type of masking, where indirect identifiers are removed from a data set to prevent the mapping back of data to an individual. Encryption refers to the overall process of protecting data via key pairs and protecting confidentiality.
