In the context of responding to an RFP (Request for Proposal), it is common to make certain assumptions about the project environment when specific details are not provided. Answer A is valid because assuming the customer has technically capable staff is essential for the successful implementation of the proposed equipment; if this is not the case, additional training or services may be needed. Answer D is a reasonable assumption as well, given that physical space and power are fundamental requirements for installing new hardware; however, this should be clarified to avoid potential issues during deployment. Answer E is also a valid assumption, especially in modern network environments where management and orchestration systems often reside on virtual machines; assuming there are adequate resources for these systems is critical for the overall solution but should be verified with the customer. These assumptions are important to present to the customer to ensure there are no misunderstandings or gaps in the project planning phase, as highlighted in Aruba Campus Access documentation.
