Explanation:
Representational State Transfer (REST) is a software architectural scheme that applies the components, connectors, and data conduits for many web applications used on the Internet. It uses and relies on the HTTP protocol and supports a variety of data formats. Extensible Markup Language (XML) and Security Assertion Markup Language (SAML) are both standards for exchanging encoded data between two parties, with XML being for more general use and SAML focused on authentication and authorization data. Secure Shell client (SSH) is a secure method for allowing remote login to systems over a network.

Explanation
It is imperative that an application perform checks when each function or portion of the application is accessed, to ensure that the user is properly authorized to access it. Without continual checks each time a function is accessed, an attacker could forge requests to access portions of the application where authorization has not been granted.

Distributed resource scheduling (DRS) is used within all clustered systems as the method for providing high availability, scaling, management, workload distribution, and the balancing of jobs and processes. None of the other choices is the correct term in this case.

The recovery point objective (RPO) sets and defines the amount of data an organization must have available or accessible to reach the predetermined level of operations necessary during a BCDR situation.
The recovery time objective (RTO) measures the amount of time necessary to recover operations to meet the BCDR plan. The recovery service level (RSL) measures the percentage of operations that would be recovered during a BCDR situation. SRE is provided as an erroneous response.
