Question 150
At Brookside Manufacturing, the industrial security team is conducting a plant safety and IT security assessment under requirements for production continuity and controlled test windows. Following the approved correction, auditors require proof that: A DNS zone transfer alert appears in a test lab but the primary authoritative DNS server configuration has not been reviewed. Which result BEST demonstrates successful remediation?
Explanation
Correct Answer
An unauthorized test client cannot transfer the zone and registered secondary servers continue normal replication. The observable result demonstrates that the documented condition, A DNS zone transfer alert appears in a test lab but the primary authoritative DNS server configuration has not been reviewed. has been addressed. The planned remediation is: Verify zone-transfer policy with the DNS owner and restrict transfers to explicitly designated secondary servers. This is a stronger validation than a saved ticket or unverified claim by Brookside Manufacturing.
Incorrect Answers
The inventory includes cloud-managed endpoints and explicitly marks legacy enumeration limitations. That observation would verify another scenario: A directory inventory relies on old NetBIOS names but many systems have migrated to cloud identity services. The corrective step for that other scenario is: Correlate legacy discovery with modern asset management and directory records rather than declaring missing NetBIOS answers absent systems. But Brookside Manufacturing is evaluating: A DNS zone transfer alert appears in a test lab but the primary authoritative DNS server configuration has not been reviewed. The necessary outcome is: An unauthorized test client cannot transfer the zone and registered secondary servers continue normal replication.
The report lists visible RPC interfaces without claiming unproven access to protected business objects. That observation would verify another scenario: A remote RPC endpoint advertises several interfaces but a reviewer interprets the interface list as proof of exposed sensitive records. The corrective step for that other scenario is: Separate service-interface discovery from authorization testing and validate data exposure only within approved roles. But Brookside Manufacturing is evaluating: A DNS zone transfer alert appears in a test lab but the primary authoritative DNS server configuration has not been reviewed. The necessary outcome is: An unauthorized test client cannot transfer the zone and registered secondary servers continue normal replication.
The assessment retains only designated service metadata and contains no unnecessary account or contact exports. That observation would verify another scenario: An enumeration script collects a full organizational directory from a test account even though the scope permits only service discovery. The corrective step for that other scenario is: Apply query and result-set minimization and use a least-privilege test identity before collecting directory attributes. But Brookside Manufacturing is evaluating: A DNS zone transfer alert appears in a test lab but the primary authoritative DNS server configuration has not been reviewed. The necessary outcome is: An unauthorized test client cannot transfer the zone and registered secondary servers continue normal replication.
