Question 330

Before reaching an audit conclusion, consider: A redundant web cluster shares one DNS resolver and becomes inaccessible when that resolver fails. Which evidence should the auditor review FIRST to evaluate this risk?

  1. Compare discovery scans, inventory records, host ownership and vendor support status.
  2. Quantify financial and operational consequences of lost transactions over time.
  3. Review rack placement, power/cooling diagrams, recovery design and fault dependencies.
  4. Map DNS architecture, cache behavior, alternate paths and outage records.

Explanation

Correct Answer

D:

Map DNS architecture, cache behavior, alternate paths and outage records. The governing principle is: Availability analysis must include upstream shared dependencies, not just redundant hosts.

Incorrect Answers

A:

Compare discovery scans, inventory records, host ownership and vendor support status. This would be relevant to a different issue such as: An IT inventory lists hundreds of production servers without owners or support end dates. In the present case, the most directly relevant audit step is: Map DNS architecture, cache behavior, alternate paths and outage records. The governing distinction is: Availability analysis must include upstream shared dependencies, not just redundant hosts.

B:

Quantify financial and operational consequences of lost transactions over time.

The governing distinction is: Availability analysis must include upstream shared dependencies, not just redundant hosts.

C:

Review rack placement, power/cooling diagrams, recovery design and fault dependencies. This would be relevant to a different issue such as: A database is replicated across two racks but both racks depend on the same cooling circuit. In the present case, the most directly relevant audit step is: Map DNS architecture, cache behavior, alternate paths and outage records. The governing distinction is: Availability analysis must include upstream shared dependencies, not just redundant hosts.

Question 331

An IS auditor evaluates this situation: An auditor exports personally identifiable records to an unsecured laptop for analytics testing. Which audit principle MOST directly applies to this situation?

  1. Evidence integrity and independence are weakened when subjects can alter the only record.
  2. Audit evidence collection must preserve confidentiality and authorized custody as well as usefulness.
  3. Audit scope must be based on independent assessment of relevant risk rather than auditee preference.
  4. A zero-exception result is unreliable if data completeness and pipeline health are unverified.

Explanation

Correct Answer

B:

Audit evidence collection must preserve confidentiality and authorized custody as well as usefulness. The corresponding audit procedure is: Check data classification, allowed extraction methods, workstation security and retention rules.

Incorrect Answers

A:

Evidence integrity and independence are weakened when subjects can alter the only record.
