ECCouncil 312-38 (Certified Network Defender) Practice Test 3

Question 20

A small retailer stores cardholder data in an internally managed payment application. Which compliance standard primarily governs protection of that cardholder environment?

  1. ISO 22301 exclusively
  2. PCI Data Security Standard (PCI DSS)
  3. A generic ISO 27001 risk treatment plan without payment-card control mapping
  4. SOC 2 reporting criteria alone
  5. A generic ISO 27001 management-system certificate alone

Explanation

Correct Answer

B:

PCI DSS addresses security controls for environments that store, process, or transmit payment-card data, subject to applicable scope.

Incorrect Answers

A:

This standard focuses on business-continuity management rather than specific payment-card data security requirements.

C:

A management-system plan may improve security, but cardholder-data requirements still need applicable PCI DSS scope and controls.

D:

A SOC 2 report can describe control assurance but is not the payment card industry's direct security standard.

E:

An ISO 27001 certification may be valuable, but it does not replace cardholder-data-specific obligations or determine PCI DSS scope automatically.

Question 21

A healthcare provider in the United States wants to identify the regulation protecting certain identifiable patient health information. Which framework is directly relevant?

  1. HIPAA Security Rule for electronic protected health information
  2. State consumer privacy law alone without reviewing HIPAA applicability
  3. PCI DSS for all medical records
  4. FERPA safeguards for student education records

Explanation

Correct Answer

A:

HIPAA imposes safeguards on covered entities and business associates handling ePHI, with applicability determined by legal role and data.

Incorrect Answers

B:

Other laws may apply, but a covered healthcare organization needs to assess HIPAA-specific ePHI security obligations.

C:

PCI DSS is relevant to payment card environments but does not generally govern the confidentiality of patient records as such.

D:

FERPA governs education records in applicable contexts, not the electronic protected health information described for a healthcare provider.

Question 22

A company processes personal information about EU residents and wants privacy requirements incorporated before deploying a new analytics service. Which approach is most appropriate?

  1. Assess GDPR obligations, data purpose, lawful basis, and privacy by design
  2. Assume encryption alone makes all processing lawful
  3. Retain every raw identifier indefinitely for flexibility
  4. Run a security penetration test but omit privacy-purpose and data-flow mapping

Explanation

Correct Answer

A:

GDPR applicability requires evaluation of processing context, and privacy controls should be built into design before collection or use.

Incorrect Answers

B:

Encryption protects confidentiality but does not establish a lawful basis, transparency, data minimization, or individual rights.

C:

Indefinite retention without purpose or necessity can conflict with data minimization and storage-limitation principles.

D:

Penetration tests can reveal technical vulnerabilities but cannot establish lawful processing, necessary data collection, retention boundaries, or data-subject rights.

Question 23

A business prepares an annual phishing awareness program. Which measurement provides the most useful evidence of behavior improvement?

  1. Treat one perfect mock test as permanent competence
  2. Count training slide pages without measuring behavior
  3. Track reporting rates and risky actions over repeated realistic exercises
  4. Measure the total bytes on the email gateway

Explanation

Correct Answer

C:

Trends in both safe reporting and harmful clicks or submissions can reveal whether training changes practical employee response.

Incorrect Answers

A:

One isolated score cannot establish durable behavior, especially as lures and social-engineering tactics evolve.

B:

Page count indicates content volume but cannot demonstrate whether staff identify or report suspicious messages.

D:

Gateway throughput says little about human recognition or escalation of carefully targeted phishing attempts.

Question 24

A network switch is retired after storing credentials and configuration secrets in local flash. What lifecycle action is essential before disposal?

  1. Perform approved sanitization and record disposition
  2. Preserve all administrative keys on the device for convenience
  3. Reset the running configuration without verifying persistent flash sanitization
  4. Update the device's hostname to a generic label

Explanation

Correct Answer

A:

Sanitizing retained data and documenting the chain of custody limits disclosure when equipment leaves organizational control.

Incorrect Answers

B:

Retaining credentials creates an avoidable exposure if the equipment is sold, recycled, or otherwise transferred.

C:

A running configuration reset changes active settings but may leave startup files, keys, and other persistent information on storage awaiting secure disposal.

D:

A cosmetic name change leaves sensitive information on persistent media and provides no disposal assurance.

Question 25

A critical firewall exception is approved for an urgent vendor project. What makes the exception governable rather than permanent drift?

  1. Allow the vendor to modify unrelated ACLs freely
  2. Keep the exception only in an engineer's private notes
  3. Disable configuration-change logging until the project ends
  4. Record a risk owner, justification, scope, expiry, and review

Explanation

Correct Answer

D:

A time-bound exception makes acceptance traceable and prompts reassessment before the bypass outlives its business need.

Incorrect Answers

A:

Unbounded privileges expand risk beyond the approved necessity and undermine accountable exception handling.

B:

Private notes reduce auditability and continuity; operational staff need an authoritative record of deviations.

C:

Suppressing logs hides changes and prevents incident reconstruction precisely while rules are being relaxed.

Question 26

A vendor provides remote support for industrial gateways. Which administrative due-diligence evidence is most relevant before granting access?

  1. Review access controls, security obligations, and incident notification terms
  2. Skip access revocation planning because support is temporary
  3. Delegate all approval power to the vendor's technician
  4. Review the vendor's uptime SLA without checking security access or breach terms

Explanation

Correct Answer

A:

Supplier assurance should establish how remote access is limited, monitored, and reported, not merely that support is available.

Incorrect Answers

B:

Temporary connectivity still requires a clear expiry and revocation path to prevent abandoned external entry points.

C:

Self-approval removes customer oversight and can give a third party inappropriate authority over production systems.

D:

Service availability commitments do not establish how privileged support sessions are controlled, logged, revoked, or reported after a security event.

Question 27

A proposed configuration change adds a new Internet-facing VPN service. Which change-management practice should occur before rollout?

  1. Disable alerting so the deployment looks clean
  2. Evaluate security impact, obtain approval, and prepare rollback
  3. Share production credentials in the change ticket
  4. Promote directly to production without a rollback path

Explanation

Correct Answer

B:

A controlled change assesses the new exposure and ensures an accountable way to restore service if deployment causes harm.

Incorrect Answers

A:

Hiding monitoring during a network change prevents defenders from distinguishing expected effects from malicious activity.

C:

Broadly exposing secrets is unnecessary to document a configuration change and creates another compromise route.

D:

Skipping review and recovery preparation turns an ordinary configuration change into preventable operational and security risk.

Question 28

An engineering manager asks whether a policy requiring regular account review is being followed. Which artifact offers the strongest evidence?

  1. The policy PDF with a current approval signature
  2. Dated access-review records with reviewers and remediation outcomes
  3. A record of generic security-news subscriptions
  4. An access-review calendar without review outcomes

Explanation

Correct Answer

B:

Records show both execution and any revoked access, unlike a policy statement describing only the intended control.

Incorrect Answers

A:

Approval documents management intent, but it cannot prove the review happened or exceptions were resolved.

C:

Receiving news demonstrates awareness of updates, not completed review of actual user entitlements.

D:

A review schedule shows planned frequency, but it does not prove that account reviewers checked entitlements or removed inappropriate access.

Question 29

A security team learns that a widely used firewall release has a newly disclosed critical flaw. Which administrative process should drive its response?

  1. Asset-based advisory triage tied to patch or mitigation ownership
  2. Delete the advisory after forwarding it to everyone
  3. Impose a maintenance freeze without evaluating exposed firewall versions
  4. Assume devices are safe because they passed last quarter's audit

Explanation

Correct Answer

A:

Matching the notice to affected inventoried products and responsible teams enables timely, risk-based treatment and verification.

Incorrect Answers

B:

Broadcast alone does not identify impacted devices, execute mitigations, or close a security finding.

C:

Change freezes may limit unintended drift, but they do not identify vulnerable deployments or provide a controlled process for applying urgent vendor fixes.

D:

A historical audit cannot account for a new vulnerability disclosed after the evidence was collected.

Question 30

A subsidiary wants to reuse a parent's security policy but operates a different legal environment. What should governance require?

  1. Perform an applicability review and adopt local control addenda
  2. Abandon all enterprise minimum standards immediately
  3. Treat network topology alone as a compliance map
  4. Copy the document unchanged without legal analysis

Explanation

Correct Answer

A:

Enterprise policies offer consistency, but requirements must be reconciled with applicable laws, contracts, and operational conditions.

Incorrect Answers

B:

Local adjustments need not eliminate baseline safeguards that remain useful across the broader organization.

C:

A topology shows connected systems, not all legal duties, data flows, processor roles, or evidence requirements.

D:

A policy written for another jurisdiction may omit required obligations or conflict with local processing constraints.
