- A
Preserve relevant endpoint, network, and application records.
- B
Document evidence collection and handling.
- C

A scanner finds a critical flaw on two systems: an internet-facing payment server with evidence of active exploitation and an isolated test machine with no sensitive data. What is the best next step?
- A
Patch the isolated test machine first because it is easier to update.
- B
Prioritize the exposed payment server, confirm business impact, and apply a tested fix or suitable interim mitigation.
- C
Defer both fixes until the next annual audit.
- D

Assess the processor's security and data-handling practices before granting access.
- B
Define security and incident-notification obligations in the agreement.
- C
Assume outsourcing removes the organization's responsibility to manage the risk.
- D
Monitor the relationship after it begins.

- B
Leave the rule in place until the next change window, regardless of risk.
- C
Delete all firewall logs to avoid confusion.
- D
Make undocumented changes to compensate.
A learner is planning Security+ review using the published domain percentages. Explain how those percentages can guide study and what they cannot predict about an individual exam form.
Which statement best describes how a security team should interpret vulnerability scan results when deciding what to remediate first?
- A
A critical scanner rating alone establishes that an attacker accessed the system.
- B
A finding should be assessed alongside exposure, exploitation evidence, asset importance, and potential impact.
- C
An isolated machine should always be patched before an exposed payment server.
- D
A vulnerability can be considered closed when a business owner asks for more time.

- C
A longer password-expiration period and an awareness poster
- D
An encrypted disk that does not protect the shared files and a vulnerability scan

Verify a digital signature using the vendor’s trusted public key
- C
Calculate a hash without a trusted reference value
- D
Store the update on an encrypted disk

Assess its security practices, define obligations in the agreement, and monitor the relationship
- C
Assume outsourcing removes the organization’s responsibility for the risk
