Final answer:
A security manager should use a Request for Information (RFI) to confirm that there are DLP solutions meeting the defined requirements, as part of the initial step in the solution evaluation and procurement process. (option E)
Step-by-step explanation:
To determine the best Data Loss Prevention (DLP) solution for an enterprise, a security manager who has outlined a list of requirements should use a Request for Information (RFI). An RFI is designed to collect general information about products, services, or suppliers and is used when a manager wants to confirm that a solution exists that meets the specified requirements. It is the first step in the procurement process, used to evaluate potential solutions before proceeding further.
In comparison, an NDA (Non-Disclosure Agreement) is for protecting sensitive information, an RFP (Request for Proposal) solicits detailed proposals from potential suppliers with the expectation of awarding a contract, an RFQ (Request for Quote) asks for detailed pricing for specific items or services, and an MSA (Master Service Agreement) outlines the terms and conditions of the work to be performed.
In the context of solution evaluation, utilizing an RFI allows the security manager to evaluate solutions based on the initial responses from vendors, which can then be assessed against the project's constraints and criteria. This structured process ensures that the most advantageous DLP solution is identified and selected, similar to the way a solar still for desalination might be chosen as the best design according to specified requirements in an engineering context.
