1. T04.E01. during the MSA phase TSN analysis, the SSEs used VA questionnaires to determine the software and supply chain vulnerabilities likelihoods.At that time all the questions were equally weighted. However the software specialist recently suggested weighting the 1^st 3 questions more heavily than the other software questions because they have more impact on the security of the system. Both the chief engineer and program manager concur. What 3 actions should the system SSEs perform? (select 3 that apply.)
   1. Conduct another protection measures trade-off analysis and revise the list of protection measures accordingly
   2. Redo the RA based on the revised VA likelihood values
   3. Redo the VA in accordance with the software specialist's recommendation
   4. Redo the TA in accordance with the software specialist's recommendation

I had previously submitted the answers as 2, 3, and 4. The question was marked wrong. since they were looking for 3 possible answers, logically choice number 1 is required. I would submit that the answer should be 1, 2, and 4. please review and advise
