ECCouncil 312-38 (Certified Network Defender) Practice Test 26

Question 250

A campuswide outage disables the usual messaging service. Which continuity action best supports incident coordination?

  1. Rely only on an unmaintained contact list from years ago
  2. Prearranged out-of-band communications with tested contact details
  3. Share confidential incident details in public social posts
  4. Require all responders to use the failed messaging platform

Explanation

Correct Answer

B:

Alternate channels let leaders and recovery teams coordinate when the primary network or messaging environment is unavailable.

Incorrect Answers

A:

Outdated contact details undermine the ability to reach responsible personnel and supplier escalation contacts.

C:

Public disclosure can expose victims and investigations while failing to establish controlled responder communication.

D:

A single unavailable channel creates a coordination dead end during precisely the event that requires communication.

Question 251

Executives need consistent public updates during a cyber-triggered outage without releasing unverified evidence. Which role/process is most appropriate?

  1. Use the authorized crisis communications process with verified updates
  2. Deny the outage exists until all investigations are complete
  3. Let every technical responder issue their own external statement
  4. Publish all forensic images to reassure customers

Explanation

Correct Answer

A:

Defined spokespeople, facts approval, and audience-specific messaging reduce confusion while respecting legal and investigative constraints.

Incorrect Answers

B:

Silence or false statements undermine stakeholder trust and may conflict with contractual or regulatory notification duties.

C:

Uncoordinated messages can contradict one another and reveal unverified or sensitive incident details.

D:

Evidence publication can disclose confidential records and does not constitute responsible crisis communications.

Question 252

After production runs in a recovery region, engineers plan to return to the repaired primary site. What should be considered before failback?

  1. Switch routing instantly without checking data currency
  2. Validate primary readiness, data synchronization, and a controlled reversal plan
  3. Discard the recovery environment before testing primary applications
  4. Reset all user passwords to the same temporary value

Explanation

Correct Answer

B:

Failback can cause another outage or data divergence unless systems, traffic, and transactional consistency are reconciled carefully.

Incorrect Answers

A:

Unsynchronized state can lose recent transactions or create split-brain conditions across the environments.

C:

Premature decommissioning removes a viable fallback and increases exposure to another primary-site failure.

D:

Uniform passwords create security risk and do not address network or data consistency during failback.

Question 253

A clustered application stays online when one node fails, but ransomware encrypts its replicated data on both nodes. What important distinction does this illustrate?

  1. Backup is unnecessary whenever a failover heartbeat is present
  2. High availability cannot replace independent recoverable backups
  3. Cluster replication guarantees historic data immutability
  4. A second active node always blocks phishing

Explanation

Correct Answer

B:

Replication supports service continuity for component failures but can propagate malicious or accidental data changes to every active copy.

Incorrect Answers

A:

Heartbeats detect node health, not the existence of clean data versions recoverable after corruption or ransomware.

C:

Replicated writes usually include unwanted changes unless separate versioned or immutable recovery controls exist.

D:

Availability architecture does not independently prevent users from executing malware or surrendering credentials.

Question 254

An organization wants evidence that its disaster recovery plan meets stated service objectives. Which TWO test results are essential? Choose TWO.

  1. Measured restoration time for critical services
  2. The duration of the tabletop meeting alone
  3. Verified age and integrity of recovered data
  4. The number of recovery runbook pages reviewed by the team
  5. The total number of pages in the recovery binder

Explanation

Correct Answers

A:

Observed recovery duration can be compared with defined RTO values rather than relying on untested estimates.

C:

The restored recovery point and correctness of records show whether RPO and integrity expectations were achieved.

Incorrect Answers

B:

An exercise's length does not establish measured service restoration time or amount of data lost during a technical recovery.

D:

Documentation review is useful preparation but does not verify the runtime characteristics or freshness of recovered data.

E:

Document length cannot demonstrate that services restart quickly or recovered data meets business requirements.

Question 255

A disaster plan accurately describes systems from three years ago but omits cloud migrations and recent vendor dependencies. What control should prevent that drift?

  1. Scheduled review tied to material architecture and business changes
  2. Removing system owners from every planning session
  3. Updating only contact information while ignoring system dependencies
  4. Freezing the document after executive sign-off forever

Explanation

Correct Answer

A:

Continuity plans must evolve with assets, providers, and business priorities so rehearsed procedures remain executable.

Incorrect Answers

B:

Excluding accountable teams makes it harder to track dependencies, validate assumptions, or execute restoration steps.

C:

Current contact lists help response, but the plan remains inaccurate if cloud services and vendor recovery paths have changed.

D:

Sign-off establishes a version's approval, not enduring correctness after substantial infrastructure changes.

Question 256

A security team evaluates a database before adding any planned controls, then reevaluates it after encryption and restricted access are implemented. Which term describes exposure before controls?

  1. Accepted risk
  2. Residual risk
  3. Inherent risk
  4. Risk transfer

Explanation

Correct Answer

C:

Inherent risk is assessed without considering selected mitigations; the later assessment estimates exposure remaining after relevant safeguards.

Incorrect Answers

A:

Accepted risk is a treatment decision authorized by a risk owner, not a generic synonym for precontrol exposure.

B:

Residual risk is what remains after controls and treatment measures, not the initial unmitigated evaluation.

D:

Transfer shifts some financial or contractual consequences but does not describe the initial exposure assessment.

Question 257

Two findings have different likelihood and business impact. Which risk-ranking approach helps leaders compare them consistently?

  1. A documented likelihood-impact evaluation with defined scales
  2. Choosing whichever asset has the most IP addresses
  3. Ranking only by how recently an alert arrived
  4. Alphabetical sorting of vulnerability names

Explanation

Correct Answer

A:

Consistent criteria make prioritization explainable and incorporate consequences, not just the technical exploit name.

Incorrect Answers

B:

Address count alone does not describe exploitability, compensating controls, or impact of a compromise.

C:

Recency can influence triage but ignores severity and business impact that determine relative treatment needs.

D:

Names do not establish exploit probability or consequences for business assets and cannot serve as defensible risk priority.

Question 258

A business unit identifies a significant network exposure. Which register field most directly establishes accountability for remediation or acceptance?

  1. A risk score with no accountable treatment owner
  2. The date the risk was first identified with no current assignee
  3. A vulnerability ticket with no accountable business risk decision maker
  4. The first letter of the attacker's possible alias
  5. A named risk owner with decision authority and due dates

Explanation

Correct Answer

E:

Accountable ownership connects each risk to a person empowered to coordinate treatment, approvals, and follow-up.

Incorrect Answers

A:

A numeric rating can assist triage, but without an accountable owner there is no responsible party for the decision.

B:

Discovery dates help maintain history, but do not establish who must authorize or complete risk treatment today.

C:

Technical tickets track work, but ownership of risk treatment and acceptance requires explicit authorized business accountability.

D:

An attacker label is not a substitute for an internal owner responsible for mitigating the business risk.

Question 259

An organization buys cyber insurance against some financial consequences of an incident. Which treatment strategy is represented?

  1. Risk transfer of specified financial exposure
  2. Technical vulnerability remediation
  3. Complete risk elimination
  4. Guaranteed acceptance of all future incidents

Explanation

Correct Answer

A:

Insurance may shift covered monetary losses to an insurer, while operational responsibility and uncovered risks still remain with the organization.

Incorrect Answers

B:

Purchasing coverage is not the same as correcting software flaws or changing network control configurations.

C:

Insurance does not remove an exploit path or guarantee that incidents and business disruption cannot happen.

D:

Policy limits and exclusions mean coverage is conditional and not a blanket authorization to tolerate any security threat.

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.
