ECCouncil 312-38 (Certified Network Defender) Practice Test 27

Question 260

A business decides to discontinue an obsolete Internet-facing service because its security exposure exceeds the benefits it provides. Which strategy applies?

  1. Risk avoidance
  2. Risk acceptance
  3. Risk monitoring without action
  4. Risk transfer

Explanation

Correct Answer

A:

Removing the activity or asset that creates the exposure avoids that specific risk rather than attempting to tolerate or insure it.

Incorrect Answers

B:

Acceptance would authorize continuing to carry the exposure, whereas the company is shutting down the risky activity.

C:

Observation alone leaves the vulnerable service online, contrary to the stated plan to remove it.

D:

Transfer reallocates some consequences but would not itself end the vulnerable service or eliminate its attack path.

Question 261

A residual risk remains after compensating controls, and leadership decides the benefit justifies the exposure. What must make that decision legitimate?

  1. Automatic approval by every vendor with network access
  2. An engineer's undocumented verbal assurance
  3. Documented acceptance by an authorized risk owner within policy thresholds
  4. Deletion of the risk register entry

Explanation

Correct Answer

C:

Formal acceptance identifies the exposure, rationale, accountability, and conditions for review rather than allowing unmanaged exceptions.

Incorrect Answers

A:

Suppliers do not normally own the enterprise's strategic decision to tolerate business security exposure.

B:

Informal approval lacks traceable authority and may bypass tolerance thresholds established by leadership.

D:

Removing evidence does not eliminate residual risk and conceals the decision from oversight and future review.

Question 262

A network team deploys segmentation and patches vulnerable edge devices to reduce the probability and reach of compromise. Which risk response is this?

  1. Risk acceptance without treatment
  2. Risk mitigation
  3. Risk avoidance by abandoning the business service
  4. Risk transfer alone

Explanation

Correct Answer

B:

Technical controls reduce likelihood or impact while acknowledging that some remaining exposure may need continued monitoring.

Incorrect Answers

A:

Acceptance permits an exposure to remain, whereas these actions actively reduce the vulnerability and movement paths.

C:

The company keeps the service operating and lowers risk, rather than eliminating the activity entirely.

D:

Patching and segmentation directly change technical exposure; they are not primarily contracts that shift losses to a third party.

Question 263

A CVSS-critical flaw exists on an isolated lab system, while a medium-rated flaw is actively exploited on a public payment gateway. Which prioritization is most defensible?

  1. Ignore the payment gateway because the CVSS score is lower
  2. Patch age measured without asset business context
  3. Always patch the numerically highest CVSS score first in every context
  4. Incorporate exploit activity, exposure, asset criticality, and compensating controls
  5. Rank solely by estimated exploitation probability without exposure or business-impact context

Explanation

Correct Answer

D:

CVSS is a useful technical input, but current threat context and business consequences determine practical remediation priority.

Incorrect Answers

A:

Real-world exploitation and criticality can make a lower base score more urgent than an isolated higher-rated weakness.

B:

Days since disclosure are useful for tracking, yet an actively exploited gateway carrying payment traffic may need faster action despite age.

C:

Numeric severity alone can miss actively exploited public paths to critical business services.

E:

A probability estimate can assist prioritization, but by itself it cannot compare business consequences, access prerequisites, or controls protecting the affected asset.

Question 264

A vulnerability scanner uses valid system credentials to inspect installed packages and configuration instead of only probing exposed ports. What is the benefit?

  1. It eliminates the need to protect scanning credentials
  2. It proves the scanner can exploit every reported weakness
  3. Authenticated assessment can reduce blind spots in local software and configuration inventory
  4. It guarantees zero false positives for every vendor product

Explanation

Correct Answer

C:

Credentialed checks often identify patch state and host settings not observable through unauthenticated network banners alone.

Incorrect Answers

A:

Scan accounts may be sensitive and require least privilege, secure storage, and rotation regardless of detection quality.

B:

Finding a vulnerable version or setting does not guarantee an exploitation path under current controls.

D:

Credentials can improve evidence but cannot remove all fingerprinting, policy, or environmental interpretation errors.

Question 265

A scanner flags an outdated service version, but manual inspection confirms the vendor backported the security fix without changing the visible banner. What is the most likely classification?

  1. False positive due to version-only inference
  2. Guaranteed data exfiltration
  3. Automatically accepted residual risk
  4. Confirmed zero-day exploitation

Explanation

Correct Answer

A:

Banner-based checks can misidentify risk when a supported distributor backports fixes; package advisories and evidence help confirm remediation.

Incorrect Answers

B:

Exfiltration requires separate evidence of unauthorized data transfer, not merely a disputed scan finding.

C:

A mistaken vulnerability detection is an evidence issue, not a documented decision to tolerate real exposure.

D:

A stale version string does not establish that the system is being actively exploited through an unknown vulnerability.

Question 266

A vulnerability is present on a database library but the vulnerable function cannot be reached from any application path in the deployed build. What should assessment distinguish?

  1. Ignore all library vulnerabilities regardless of future changes
  2. Vulnerable component presence from an actually reachable exploit path
  3. Treat a published CVE as proof of completed attacker access
  4. Assume every installed library is always Internet reachable

Explanation

Correct Answer

B:

Exposure analysis evaluates prerequisites, code reachability, and compensating controls rather than equating installed code with immediate exploitability.

Incorrect Answers

A:

Current reachability may change with releases or configuration, so inventory and monitoring remain necessary.

C:

A disclosure identifies a weakness but does not show that adversaries exploited this specific deployment.

D:

Deployment and application call paths govern exposure; a package's presence alone does not prove remote invocation.

Question 267

A severe externally reachable firewall defect has a seven-day remediation target, but owners want to postpone it without controls. What should the program enforce?

  1. Removal of the device from all vulnerability reports
  2. Unlimited deferral without any recorded risk decision
  3. Automatic closure when a ticket is assigned
  4. A risk-based patch SLA with escalation and documented exception controls

Explanation

Correct Answer

D:

Service-level remediation targets need accountable owners and formal approval for justified delays, especially when exposure is critical.

Incorrect Answers

A:

Suppressing the finding hides incomplete work without reducing the exploited condition.

B:

Indefinite unmanaged delay leaves the edge exposure open and undermines policy enforcement.

C:

Assignment begins remediation, but closing before patch or valid mitigation verification falsely signals completion.

Question 268

A legacy operating system cannot receive a needed security patch for three months. Which treatment is an appropriate interim compensating control?

  1. Disable every security alert originating from the host
  2. Tighten isolation, restrict access, increase monitoring, and schedule replacement
  3. Make the legacy host a general-purpose jump server
  4. Allow anonymous access so support is easier

Explanation

Correct Answer

B:

Layered restrictions can reduce attack reachability while a tracked exception acknowledges the unresolved underlying vulnerability.

Incorrect Answers

A:

Suppression removes signals of exploitation instead of compensating for the unpatched condition.

C:

Additional administrative use increases connections and exposure precisely while the system remains vulnerable.

D:

Anonymous access creates a new weakness and cannot substitute for timely remediation or controlled isolation.

Question 269

A new employee analytics feature will aggregate detailed location data and share it with a processor. Which TWO inputs belong in a privacy impact assessment? Choose TWO.

  1. Assume location observations are never personal data
  2. Evaluate individual privacy risks and necessary safeguards
  3. Publish raw employee trajectories to simplify audit
  4. Map the personal data, processing purpose, and involved parties
  5. Ignore external processor arrangements entirely

Explanation

Correct Answers

B:

A PIA assesses potential harm and whether minimization, access controls, transparency, and other mitigations are sufficient.

D:

Understanding collection and flows reveals where sensitive information is used, stored, disclosed, and retained.

Incorrect Answers

A:

Contextual movement data may identify individuals, so that assumption could hide significant obligations.

C:

Unrestricted disclosure increases privacy risk and is not required for assessing the processing activity.

E:

Third-party recipients can introduce critical security, contract, jurisdictional, and retention considerations.

Question 270

A formal risk program has implemented controls and needs to ensure exposure remains acceptable as business systems change. Which TWO activities support continuous monitoring? Choose TWO.

  1. Review emerging threats, control performance, and material environment changes
  2. Freeze every assessment score permanently after initial approval
  3. Remove all residual risks from management reporting
  4. Treat a completed audit as proof that no future threats can emerge
  5. Report deviations and treatment progress to accountable risk owners

Explanation

Correct Answers

A:

Risk changes with vulnerabilities, architecture, and attacker behavior, making periodic reassessment necessary.

E:

Governance needs evidence that controls work and exceptions or remediation deadlines are handled appropriately.

Incorrect Answers

B:

Static scores become outdated when systems, dependencies, and threat conditions change.

C:

Unreported exposure cannot be evaluated against business tolerance or revisited by authorized decision makers.

D:

An audit represents limited evidence at a point in time and cannot guarantee enduring immunity from new attack paths.
