ECCouncil 312-49v11 (Computer Hacking Forensic Investigator) Practice Test 10

Question 90

A portable forensic drive could be lost in transit, exposing copied personal records. Which protective measure reduces disclosure risk if the media is stolen?

  1. Least privilege
  2. Encryption at rest
  3. Purpose limitation
  4. Redaction for disclosure

Explanation

Correct Answer

B:

Encryption at rest protects readable content when keys remain separate and appropriately controlled. It does not replace custody records or secure physical handling.

Incorrect Answers

A:

For the separate question of narrow access appropriate to a review role, least privilege grants only the capabilities needed for the task and duration; the requested assessment of confidentiality of a misplaced forensic drive remains open. Separate reviewer roles reduce accidental modification and unnecessary exposure; there is no direct finding about confidentiality of a misplaced forensic drive.

C:

For a separate investigation of using evidence only for justified purposes, purpose limitation constrains reuse to compatible or separately authorized purposes under the governing rules; that is not the determination of confidentiality of a misplaced forensic drive in the stem. Forensic possession does not create unrestricted secondary use rights; the evidence still must speak to confidentiality of a misplaced forensic drive.

D:

With confidentiality of a misplaced forensic drive as the investigative issue, redaction removes or masks irrelevant sensitive details from the disclosure copy, retaining a controlled original where required; the result would concern protecting unrelated identities in a shared report. Removing material must not misrepresent the underlying findings; this would not resolve confidentiality of a misplaced forensic drive.

Question 91

A report reviewer needs read-only access to a subset of exhibits, not full administrative control of the case database. Which access principle applies?

  1. Purpose limitation
  2. Redaction for disclosure
  3. Retention schedule
  4. Least privilege
  5. Confidentiality agreement

Explanation

Correct Answer

D:

Least privilege grants only the capabilities needed for the task and duration. Separate reviewer roles reduce accidental modification and unnecessary exposure.

Incorrect Answers

A:

In work concerning using evidence only for justified purposes, purpose limitation constrains reuse to compatible or separately authorized purposes under the governing rules; the operation would not resolve narrow access appropriate to a review role. Forensic possession does not create unrestricted secondary use rights; the distinction leaves narrow access appropriate to a review role unsettled.

B:

A case involving protecting unrelated identities in a shared report might use this approach: redaction removes or masks irrelevant sensitive details from the disclosure copy, retaining a controlled original where required; the required result here is narrow access appropriate to a review role. Removing material must not misrepresent the underlying findings; it cannot replace proof about narrow access appropriate to a review role.

C:

The required finding is about narrow access appropriate to a review role; retention schedules define periods and disposition rules by record class, subject to legal obligations; this addresses the separate concern of defined end-of-life rules for case records. The investigator must confirm no hold or statute requires longer preservation; it does not by itself answer narrow access appropriate to a review role.

E:

For an analysis centered on binding restrictions on sharing sensitive case material, a confidentiality agreement can define acceptable use and disclosure restrictions for a retained specialist; the present need is narrow access appropriate to a review role. It does not independently authorize access to evidence or replace technical safeguards; a different finding about narrow access appropriate to a review role is still needed.

Question 92

An external consultant will examine employee messages subject to strict nondisclosure requirements. Which contractual control is directly relevant?

  1. Redaction for disclosure
  2. Retention schedule
  3. Confidentiality agreement
  4. Encryption at rest

Explanation

Correct Answer

C:

A confidentiality agreement can define acceptable use and disclosure restrictions for a retained specialist. It does not independently authorize access to evidence or replace technical safeguards.

Incorrect Answers

A:

In an inquiry concerning protecting unrelated identities in a shared report, redaction removes or masks irrelevant sensitive details from the disclosure copy, retaining a controlled original where required; the scope does not extend to binding restrictions on sharing sensitive case material. Removing material must not misrepresent the underlying findings; that issue cannot settle binding restrictions on sharing sensitive case material.

B:

Even though the scenario needs binding restrictions on sharing sensitive case material, retention schedules define periods and disposition rules by record class, subject to legal obligations; the action relates to defined end-of-life rules for case records. The investigator must confirm no hold or statute requires longer preservation; this remains insufficient for binding restrictions on sharing sensitive case material.

D:

The objective here is binding restrictions on sharing sensitive case material; encryption at rest protects readable content when keys remain separate and appropriately controlled; the option would instead inform confidentiality of a misplaced forensic drive. It does not replace custody records or secure physical handling; it is not direct evidence of binding restrictions on sharing sensitive case material.

Question 93

An investigation establishes unauthorized access to regulated personal data. Which compliance decision is needed next?

  1. Encryption at rest
  2. Redaction for disclosure
  3. Breach notification assessment
  4. Data minimization
  5. Access logging

Explanation

Correct Answer

C:

Notification assessment compares actual exposure, data categories and applicable thresholds against legal deadlines. It should not be inferred merely from the existence of malware.

Incorrect Answers

A:

The stem asks about whether statutory notification duties are triggered; encryption at rest protects readable content when keys remain separate and appropriately controlled; the described operation is used for confidentiality of a misplaced forensic drive. It does not replace custody records or secure physical handling; a determination about whether statutory notification duties are triggered requires other support.

B:

Instead of a method addressing whether statutory notification duties are triggered, redaction removes or masks irrelevant sensitive details from the disclosure copy, retaining a controlled original where required; this one concerns protecting unrelated identities in a shared report. Removing material must not misrepresent the underlying findings; it cannot independently determine whether statutory notification duties are triggered.

D:

A case involving avoiding unnecessary personal-data collection might use this approach: data minimization limits collection to what is necessary and proportionate for the lawful purpose where applicable; the required result here is whether statutory notification duties are triggered. Broad acquisition requires a documented justification and safeguards; it cannot replace proof about whether statutory notification duties are triggered.

E:

The required finding is about whether statutory notification duties are triggered; access logging records authenticated interactions with protected materials, enabling after-the-fact review; this addresses the separate concern of traceability of evidence repository access. It complements authorization but does not prevent every improper disclosure; it does not by itself answer whether statutory notification duties are triggered.

Question 94

An evidence image containing resident data will be sent to a laboratory in another country. Which compliance question must be resolved?

  1. Data minimization
  2. Purpose limitation
  3. Retention schedule
  4. Cross-border transfer assessment
  5. Breach notification assessment

Explanation

Correct Answer

D:

Cross-border transfer assessment examines lawful transfer mechanisms, data residency limits and processor safeguards. Encryption does not by itself waive every geographic restriction.

Incorrect Answers

A:

When the investigative task is avoiding unnecessary personal-data collection, data minimization limits collection to what is necessary and proportionate for the lawful purpose where applicable; that differs from the question about lawfulness of relocating personal evidence abroad. Broad acquisition requires a documented justification and safeguards; that leaves lawfulness of relocating personal evidence abroad unresolved.

B:

The current inquiry asks about lawfulness of relocating personal evidence abroad; purpose limitation constrains reuse to compatible or separately authorized purposes under the governing rules; this mechanism chiefly addresses using evidence only for justified purposes. Forensic possession does not create unrestricted secondary use rights; it cannot prove lawfulness of relocating personal evidence abroad on its own.

C:

In an inquiry concerning defined end-of-life rules for case records, retention schedules define periods and disposition rules by record class, subject to legal obligations; the scope does not extend to lawfulness of relocating personal evidence abroad. The investigator must confirm no hold or statute requires longer preservation; that issue cannot settle lawfulness of relocating personal evidence abroad.

E:

For the separate question of whether statutory notification duties are triggered, notification assessment compares actual exposure, data categories and applicable thresholds against legal deadlines; the requested assessment of lawfulness of relocating personal evidence abroad remains open. It should not be inferred merely from the existence of malware; there is no direct finding about lawfulness of relocating personal evidence abroad.

Question 95

A report will go to an outside party but contains unrelated patients' identifiers. Which practice reduces unnecessary exposure?

  1. Redaction for disclosure
  2. Retention schedule
  3. Access logging
  4. Breach notification assessment

Explanation

Correct Answer

A:

Redaction removes or masks irrelevant sensitive details from the disclosure copy, retaining a controlled original where required. Removing material must not misrepresent the underlying findings.

Incorrect Answers

B:

For questions about defined end-of-life rules for case records, retention schedules define periods and disposition rules by record class, subject to legal obligations; that differs from protecting unrelated identities in a shared report. The investigator must confirm no hold or statute requires longer preservation; it provides no direct answer to protecting unrelated identities in a shared report.

C:

The stem asks about protecting unrelated identities in a shared report; access logging records authenticated interactions with protected materials, enabling after-the-fact review; the described operation is used for traceability of evidence repository access. It complements authorization but does not prevent every improper disclosure; a determination about protecting unrelated identities in a shared report requires other support.

D:

Instead of a method addressing protecting unrelated identities in a shared report, notification assessment compares actual exposure, data categories and applicable thresholds against legal deadlines; this one concerns whether statutory notification duties are triggered. It should not be inferred merely from the existence of malware; it cannot independently determine protecting unrelated identities in a shared report.

Question 96

Counsel expects a civil dispute and relevant email may be deleted by standard retention rules. What instruction should be issued?

  1. Custodian identification
  2. Native production
  3. Search term validation
  4. Privilege review
  5. Litigation hold

Explanation

Correct Answer

E:

A litigation hold suspends ordinary deletion of identified potentially relevant information. Custodians must understand scope and preservation duties until release.

Incorrect Answers

A:

Although the case asks about preservation against scheduled deletion, custodian identification maps likely holders, repositories and communication channels; the action instead concerns finding people and systems holding responsive records. Searching every employee account without this step can be costly and disproportionate; it does not establish preservation against scheduled deletion.

B:

For an analysis centered on access to spreadsheet formulas and internal structure, native production supplies the source application's file format so underlying structure and formulas can be examined; the present need is preservation against scheduled deletion. Protective measures may still be needed for unrelated hidden data; a different finding about preservation against scheduled deletion is still needed.

C:

When the investigative task is effectiveness of a discovery search strategy, search validation checks precision and recall against representative or known material, prompting adjusted terms or methods; that differs from the question about preservation against scheduled deletion. Keyword lists should not be trusted without testing their performance; that leaves preservation against scheduled deletion unresolved.

D:

The current inquiry asks about preservation against scheduled deletion; legal privilege review assesses whether protected communications must be withheld or specially handled under applicable rules; this mechanism chiefly addresses potentially protected lawyer-client communications. The presence of an attorney's name is not, by itself, conclusive; it cannot prove preservation against scheduled deletion on its own.

Question 97

A legal team must determine which staff and systems may possess records relevant to contract negotiations. Which discovery step comes first?

  1. Collection defensibility
  2. Search term validation
  3. Native production
  4. Custodian identification

Explanation

Correct Answer

D:

Custodian identification maps likely holders, repositories and communication channels. Searching every employee account without this step can be costly and disproportionate.

Incorrect Answers

A:

The objective here is finding people and systems holding responsive records; defensible collection requires repeatable, documented scope and methods so the process can be scrutinized; the option would instead inform reproducibility of discovery collection. An exported file alone cannot explain why relevant items might be missing; it is not direct evidence of finding people and systems holding responsive records.

B:

For a separate investigation of effectiveness of a discovery search strategy, search validation checks precision and recall against representative or known material, prompting adjusted terms or methods; that is not the determination of finding people and systems holding responsive records in the stem. Keyword lists should not be trusted without testing their performance; the evidence still must speak to finding people and systems holding responsive records.

C:

With finding people and systems holding responsive records as the investigative issue, native production supplies the source application's file format so underlying structure and formulas can be examined; the result would concern access to spreadsheet formulas and internal structure. Protective measures may still be needed for unrelated hidden data; this would not resolve finding people and systems holding responsive records.

Question 98

A mailbox export lacks documentation of the search query, time range or tool version. Which quality property is most at risk?

  1. Search term validation
  2. Native production
  3. Collection defensibility
  4. Metadata preservation

Explanation

Correct Answer

C:

Defensible collection requires repeatable, documented scope and methods so the process can be scrutinized. An exported file alone cannot explain why relevant items might be missing.

Incorrect Answers

A:

A case involving effectiveness of a discovery search strategy might use this approach: search validation checks precision and recall against representative or known material, prompting adjusted terms or methods; the required result here is reproducibility of discovery collection. Keyword lists should not be trusted without testing their performance; it cannot replace proof about reproducibility of discovery collection.

B:

The required finding is about reproducibility of discovery collection; native production supplies the source application's file format so underlying structure and formulas can be examined; this addresses the separate concern of access to spreadsheet formulas and internal structure. Protective measures may still be needed for unrelated hidden data; it does not by itself answer reproducibility of discovery collection.

D:

For an analysis centered on maintaining original document context during export, metadata preservation retains context such as creator, dates and file attributes when material to the case; the present need is reproducibility of discovery collection. A transformed readable copy may omit information needed to assess origin or chronology; a different finding about reproducibility of discovery collection is still needed.

Question 99

A large document review contains identical attachments copied through multiple mailboxes. Which processing operation reduces redundant review?

  1. Processing deduplication
  2. Collection defensibility
  3. Custodian identification
  4. Litigation hold

Explanation

Correct Answer

A:

Deduplication identifies matching items by appropriate content and metadata criteria while preserving custodian relationships. It must not erase evidence of who possessed a copy.

Incorrect Answers

B:

For the separate question of reproducibility of discovery collection, defensible collection requires repeatable, documented scope and methods so the process can be scrutinized; the requested assessment of redundant documents without loss of provenance remains open. An exported file alone cannot explain why relevant items might be missing; there is no direct finding about redundant documents without loss of provenance.

C:

The objective here is redundant documents without loss of provenance; custodian identification maps likely holders, repositories and communication channels; the option would instead inform finding people and systems holding responsive records. Searching every employee account without this step can be costly and disproportionate; it is not direct evidence of redundant documents without loss of provenance.

D:

For a separate investigation of preservation against scheduled deletion, a litigation hold suspends ordinary deletion of identified potentially relevant information; that is not the determination of redundant documents without loss of provenance in the stem. Custodians must understand scope and preservation duties until release; the evidence still must speak to redundant documents without loss of provenance.

Question 100

An eDiscovery set contains communications requesting confidential legal advice from counsel. Which review category needs attention?

  1. Privilege review
  2. Search term validation
  3. Metadata preservation
  4. Litigation hold

Explanation

Correct Answer

A:

Legal privilege review assesses whether protected communications must be withheld or specially handled under applicable rules. The presence of an attorney's name is not, by itself, conclusive.

Incorrect Answers

B:

In work concerning effectiveness of a discovery search strategy, search validation checks precision and recall against representative or known material, prompting adjusted terms or methods; the operation would not resolve potentially protected lawyer-client communications. Keyword lists should not be trusted without testing their performance; the distinction leaves potentially protected lawyer-client communications unsettled.

C:

A case involving maintaining original document context during export might use this approach: metadata preservation retains context such as creator, dates and file attributes when material to the case; the required result here is potentially protected lawyer-client communications. A transformed readable copy may omit information needed to assess origin or chronology; it cannot replace proof about potentially protected lawyer-client communications.

D:

The required finding is about potentially protected lawyer-client communications; a litigation hold suspends ordinary deletion of identified potentially relevant information; this addresses the separate concern of preservation against scheduled deletion. Custodians must understand scope and preservation duties until release; it does not by itself answer potentially protected lawyer-client communications.
