Question

Difficulty: MediumConditional Logic and Formal Deductions

An enterprise software firm achieves ISO certification only if it implements end-to-end data encryption across all servers. Implementing end-to-end data encryption requires adopting a zero-trust network architecture. Furthermore, an enterprise software firm is permitted to bid on high-security municipal contracts only if it achieves ISO certification. Firm Apex is currently permitted to bid on high-security municipal contracts.

If the statements above are true, which of the following must also be true about Firm Apex?

  1. Firm Apex has adopted a zero-trust network architecture.Answer
  2. B
    If Firm Apex adopts a zero-trust network architecture, it will automatically be awarded a municipal contract.
  3. C
    Adopting a zero-trust network architecture is sufficient to grant a firm permission to bid on high-security municipal contracts.
  4. D
    Any firm that implements end-to-end data encryption is permitted to bid on high-security municipal contracts.
  5. E
    Firm Apex spends more on network security than other software firms competing for municipal contracts.

Answer

Firm Apex has adopted a zero-trust network architecture.
The correct answer is derived from chaining the formal conditional rules provided: Permitted to Bid requires ISO Certification, which requires End-to-End Encryption, which requires Zero-Trust Architecture. Since Firm Apex is permitted to bid, it must satisfy all necessary prerequisites along the chain, including adopting a zero-trust network architecture.

Step-by-Step Solution

1
Analyze the conditional premises in the passage
Premise 1: ISO Certification → End-to-End Encryption
Premise 2: End-to-End Encryption → Zero-Trust Architecture
Premise 3: Permitted to Bid → ISO Certification
Indicator words like 'only if' and 'requires' establish necessary conditions.
2
Chain the conditional statements transitively
Permitted to Bid → ISO Certification → End-to-End Encryption → Zero-Trust Architecture
Since each necessary condition links to the next, we can form a valid transitive deduction chain.
3
Apply the given fact about Firm Apex to the chain
Firm Apex is Permitted to Bid → Firm Apex MUST have adopted Zero-Trust Architecture
If the sufficient condition (Permitted to Bid) is true, all necessary conditions in the chain must also be true.
