Which of the following is the concept of segregating information or processes, within the same system or application, for security reasons?
Correct Answer:
B
Sandboxing involves the segregation and isolation of information or processes from other information or processes within the same system or application, typically for security concerns. Sandboxing is generally used for data isolation (for example, keeping different communities and populations of users isolated from others with similar data). In IT terminology, pooling typically means bringing together and consolidating resources or services, not segregating or separating them. Cell blocking and fencing are both erroneous terms.

What process is used within a clustered system to provide high availability and load balancing?
Correct Answer:
D
Dynamic resource scheduling (DRS) is used within all clustering systems as the method for clusters to provide high availability, scaling, management, and workload distribution and balancing of jobs and processes. From a physical infrastructure perspective, DRS is used to balance compute loads between physical hosts in a cloud to maintain the desired thresholds and limits on the physical hosts.

Cloud systems are increasingly used for BCDR solutions for organizations. What aspect of cloud computing makes their use for BCDR the most attractive?
Correct Answer:
B
Business continuity and disaster recovery (BCDR) solutions largely sit idle until they are actually needed. This traditionally has led to increased costs for an organization because physical hardware must be purchased and operational but is not used. By using a cloud system, an organization will only pay for systems when they are being used and only for the duration of use, thus eliminating the need for extra hardware and costs. Portability is the ability to easily move services among different cloud providers. Broad network access allows access to users and staff from anywhere and from different clients, and although this would be important for a BCDR situation, it is not the best answer in this case. On-demand self-service allows users to provision services automatically and when needed, and although this too would be important for BCDR situations, it is not the best answer because it does not address costs or the biggest benefits to an organization.

DLP solutions can aid in deterring loss due to which of the following?
Correct Answer:
C
DLP solutions may protect against inadvertent disclosure. Randomization is a technique for obscuring data, not a risk to data. DLP tools will not protect against risks from natural disasters, or against impacts due to device failure.
