What is the purpose of the validate step in the EPT design process?
A . During this step, the configuration available on the involved network elements is compared with the design provided byEPT.
B. This step is used to measure optical power performances over an existing network before making changes.
C. This step is optional and is useful to verify the network element layout before going through the commission step.
D. During this step, the run design action is triggered for network design consistency check and errors fixing.

Answer: D

Explanation:

The validate step in the EPT design process is used to trigger the run design action, which is responsible for verifying the consistency of the network design and fixing any errors that may exist. During the validation process, the system will compare the configuration available on the involved network elements and the design provided by EPT, and any discrepancies will be flagged for further investigation or correction.
