ECCouncil 312-49v11 (Computer Hacking Forensic Investigator) Practice Test 7

Question 60

A temperature sensor sends believable but false measurements after its calibration table is altered. Which integrity threat is involved?

  1. Bluetooth attack surface
  2. Mobile application sideloading
  3. Mobile stalkerware
  4. IoT telemetry manipulation

Explanation

Correct Answer

D:

Telemetry manipulation compromises the trustworthiness of sensor output without necessarily interrupting connectivity. Investigators compare calibration, firmware and independent physical readings.

Incorrect Answers

A:

In an inquiry concerning nearby peer connectivity through Bluetooth, bluetooth radio pairing and service exposure create a separate local attack surface; the scope does not extend to falsification of device measurement data. Logs and captures may be limited, so device settings and peer history matter; that issue cannot settle falsification of device measurement data.

B:

Even though the scenario needs falsification of device measurement data, sideloading installs application packages through alternate distribution methods; the action relates to an app installed outside the approved distribution channel. The package source and signing information matter; sideloading alone does not prove maliciousness; this remains insufficient for falsification of device measurement data.

C:

For the separate question of covert surveillance of device owner activity, stalkerware covertly monitors personal activity and transmits it to an operator; the requested assessment of falsification of device measurement data remains open. Permissions, persistence, and outbound endpoints require careful contextual assessment; there is no direct finding about falsification of device measurement data.

Question 61

At a seizure, one person must document immediate scene conditions; afterward another must manage controlled storage and handover records. Which TWO roles directly correspond to those responsibilities? Choose TWO.

  1. Evidence custodian
  2. First responder
  3. Case manager
  4. Network forensic analyst
  5. Malware reverse engineer

Explanation

Correct Answers

A:

In this combined inquiry, an evidence custodian oversees identification, secure storage, access and transfer records; the record must link a uniquely marked item to each handling event. This addresses traceability of evidence handovers.

B:

In this combined inquiry, a first responder records conditions, prevents avoidable disturbance and coordinates collection using approved procedures; untrained experimentation can destroy ephemeral evidence. This addresses initial handling of an active evidence scene.

Incorrect Answers

C:

In work concerning coordination of case records and investigative progress, a case manager tracks scope, assignments, exhibits, deadlines and review status; the operation would not resolve both initial handling of an active evidence scene and traceability of evidence handovers. This preserves coherence across an investigation without implying authority to alter evidence; the distinction leaves both initial handling of an active evidence scene and traceability of evidence handovers unsettled.

D:

A case involving reconstruction of network activity across devices might use this approach: network forensics correlates flow records, packets, address assignments and device clocks to reconstruct communications; the required result here is both initial handling of an active evidence scene and traceability of evidence handovers. It provides network-level context but may not identify the person at a keyboard; it cannot replace proof about both initial handling of an active evidence scene and traceability of evidence handovers.

E:

The required finding is about both initial handling of an active evidence scene and traceability of evidence handovers; a reverse engineer studies program structure, instructions and execution behavior in controlled conditions; this addresses the separate concern of technical understanding of suspicious executable code. This analysis differs from writing a custody log or gathering witness statements; it does not by itself answer both initial handling of an active evidence scene and traceability of evidence handovers.

Question 62

A lab specialist interprets disk artifacts and documents reproducible technical findings, without deciding criminal charges. Which role is described?

  1. Forensic examiner
  2. Case manager
  3. Malware reverse engineer
  4. Network forensic analyst

Explanation

Correct Answer

A:

The examiner applies validated examination methods, notes limitations and reports interpretations supported by artifacts. Charging decisions belong to legal authorities.

Incorrect Answers

B:

The current inquiry asks about technical analysis of acquired evidence; a case manager tracks scope, assignments, exhibits, deadlines and review status; this mechanism chiefly addresses coordination of case records and investigative progress. This preserves coherence across an investigation without implying authority to alter evidence; it cannot prove technical analysis of acquired evidence on its own.

C:

In an inquiry concerning technical understanding of suspicious executable code, a reverse engineer studies program structure, instructions and execution behavior in controlled conditions; the scope does not extend to technical analysis of acquired evidence. This analysis differs from writing a custody log or gathering witness statements; that issue cannot settle technical analysis of acquired evidence.

D:

Even though the scenario needs technical analysis of acquired evidence, network forensics correlates flow records, packets, address assignments and device clocks to reconstruct communications; the action relates to reconstruction of network activity across devices. It provides network-level context but may not identify the person at a keyboard; this remains insufficient for technical analysis of acquired evidence.

Question 63

Several teams compete for access to affected servers and need a single authority to sequence actions. Which coordination role is most useful?

  1. Evidence custodian
  2. Legal counsel
  3. Incident commander
  4. Case manager

Explanation

Correct Answer

C:

The incident commander establishes response priorities, assigns responsibility and manages trade-offs between containment and preservation. This function does not replace specialized evidence examination.

Incorrect Answers

A:

With coordination of competing response activities as the investigative issue, an evidence custodian oversees identification, secure storage, access and transfer records; the result would concern traceability of evidence handovers. The record must link a uniquely marked item to each handling event; this would not resolve coordination of competing response activities.

B:

For questions about lawful authority for proposed data collection, legal counsel assesses governing law, authorization and jurisdiction-specific constraints; that differs from coordination of competing response activities. Technical access to an account is not equivalent to legal permission to seize its contents; it provides no direct answer to coordination of competing response activities.

D:

Instead of a method addressing coordination of competing response activities, a case manager tracks scope, assignments, exhibits, deadlines and review status; this one concerns coordination of case records and investigative progress. This preserves coherence across an investigation without implying authority to alter evidence; it cannot independently determine coordination of competing response activities.

Question 64

Investigators need to determine whether a proposed cross-border mailbox collection falls within consent and legal process. Which adviser should define the permissible authority?

  1. Evidence custodian
  2. Network forensic analyst
  3. Expert witness
  4. Legal counsel

Explanation

Correct Answer

D:

Legal counsel assesses governing law, authorization and jurisdiction-specific constraints. Technical access to an account is not equivalent to legal permission to seize its contents.

Incorrect Answers

A:

Although the case asks about lawful authority for proposed data collection, an evidence custodian oversees identification, secure storage, access and transfer records; the action instead concerns traceability of evidence handovers. The record must link a uniquely marked item to each handling event; it does not establish lawful authority for proposed data collection.

B:

For an analysis centered on reconstruction of network activity across devices, network forensics correlates flow records, packets, address assignments and device clocks to reconstruct communications; the present need is lawful authority for proposed data collection. It provides network-level context but may not identify the person at a keyboard; a different finding about lawful authority for proposed data collection is still needed.

C:

When the investigative task is professional technical testimony under examination, an expert witness explains methods, findings and limitations transparently under applicable evidentiary rules; that differs from the question about lawful authority for proposed data collection. Objectivity requires separating observations from inferences; that leaves lawful authority for proposed data collection unresolved.

Question 65

Three analysts will use the same seized drive in sequence and transfers must be independently traceable. Which role owns the custody record and controlled storage?

  1. Evidence custodian
  2. First responder
  3. Forensic examiner
  4. Case manager

Explanation

Correct Answer

A:

An evidence custodian oversees identification, secure storage, access and transfer records. The record must link a uniquely marked item to each handling event.

Incorrect Answers

B:

For a separate investigation of initial handling of an active evidence scene, a first responder records conditions, prevents avoidable disturbance and coordinates collection using approved procedures; that is not the determination of traceability of evidence handovers in the stem. Untrained experimentation can destroy ephemeral evidence; the evidence still must speak to traceability of evidence handovers.

C:

With traceability of evidence handovers as the investigative issue, the examiner applies validated examination methods, notes limitations and reports interpretations supported by artifacts; the result would concern technical analysis of acquired evidence. Charging decisions belong to legal authorities; this would not resolve traceability of evidence handovers.

D:

For questions about coordination of case records and investigative progress, a case manager tracks scope, assignments, exhibits, deadlines and review status; that differs from traceability of evidence handovers. This preserves coherence across an investigation without implying authority to alter evidence; it provides no direct answer to traceability of evidence handovers.

Question 66

The team needs historical infrastructure relationships for a malware family, not a disk image interpretation. Which specialty contributes most directly?

  1. Legal counsel
  2. Incident commander
  3. Threat intelligence analyst
  4. Expert witness

Explanation

Correct Answer

C:

Threat intelligence work analyzes indicators, actor behaviors and campaign context from diverse sources. It supports investigative leads without independently proving an individual perpetrator.

Incorrect Answers

A:

A case involving lawful authority for proposed data collection might use this approach: legal counsel assesses governing law, authorization and jurisdiction-specific constraints; the required result here is historical context about adversary infrastructure. Technical access to an account is not equivalent to legal permission to seize its contents; it cannot replace proof about historical context about adversary infrastructure.

B:

The required finding is about historical context about adversary infrastructure; the incident commander establishes response priorities, assigns responsibility and manages trade-offs between containment and preservation; this addresses the separate concern of coordination of competing response activities. This function does not replace specialized evidence examination; it does not by itself answer historical context about adversary infrastructure.

D:

For an analysis centered on professional technical testimony under examination, an expert witness explains methods, findings and limitations transparently under applicable evidentiary rules; the present need is historical context about adversary infrastructure. Objectivity requires separating observations from inferences; a different finding about historical context about adversary infrastructure is still needed.

Question 67

A packed executable has unknown capabilities and the team needs code-level behavior analysis. Which specialist should lead that task?

  1. Malware reverse engineer
  2. Evidence custodian
  3. First responder
  4. Forensic examiner

Explanation

Correct Answer

A:

A reverse engineer studies program structure, instructions and execution behavior in controlled conditions. This analysis differs from writing a custody log or gathering witness statements.

Incorrect Answers

B:

For the separate question of traceability of evidence handovers, an evidence custodian oversees identification, secure storage, access and transfer records; the requested assessment of technical understanding of suspicious executable code remains open. The record must link a uniquely marked item to each handling event; there is no direct finding about technical understanding of suspicious executable code.

C:

The objective here is technical understanding of suspicious executable code; a first responder records conditions, prevents avoidable disturbance and coordinates collection using approved procedures; the option would instead inform initial handling of an active evidence scene. Untrained experimentation can destroy ephemeral evidence; it is not direct evidence of technical understanding of suspicious executable code.

D:

For a separate investigation of technical analysis of acquired evidence, the examiner applies validated examination methods, notes limitations and reports interpretations supported by artifacts; that is not the determination of technical understanding of suspicious executable code in the stem. Charging decisions belong to legal authorities; the evidence still must speak to technical understanding of suspicious executable code.
