ECCouncil 312-49v11 (Computer Hacking Forensic Investigator) Practice Test 47

Question 460

A failing drive has unreadable regions and must be imaged with resumable retries and a mapfile. Which Linux utility is well suited?

  1. Software write blocker
  2. ewfacquire
  3. ddrescue
  4. Hardware write blocker

Explanation

Correct Answer

C:

GNU ddrescue tracks completed and failed regions in a mapfile, enabling staged recovery from damaged media. It prioritizes recovering readable sectors and cannot restore physically lost bytes.

Incorrect Answers

A:

In an inquiry concerning OS-level read-only access to evidence storage, software write blocking enforces read-only device access through OS or driver controls, but its coverage depends on configuration and bypass paths; the scope does not extend to resumable recovery imaging from damaged storage. It requires validation before relying on it; that issue cannot settle resumable recovery imaging from damaged storage.

B:

Even though the scenario needs resumable recovery imaging from damaged storage, ewfacquire captures sources into EWF containers with associated acquisition options and metadata; the action relates to direct acquisition into an EWF container. Integrity verification is a separate step that should be performed and recorded; this remains insufficient for resumable recovery imaging from damaged storage.

D:

The objective here is resumable recovery imaging from damaged storage; a validated hardware write blocker mediates access to evidence storage and blocks writes in its supported modes; the option would instead inform physical mediation of write commands to a source drive. The team must test correct operation with the actual interface; it is not direct evidence of resumable recovery imaging from damaged storage.

Question 461

An examiner wants a case-oriented GUI for browsing disk images, ingest modules, file recovery and artifact review. Which forensic platform fits?

  1. The Sleuth Kit fls
  2. Autopsy
  3. The Sleuth Kit icat
  4. PhotoRec

Explanation

Correct Answer

B:

Autopsy provides a graphical investigation environment built around filesystem and artifact analysis capabilities. Results still depend on tool settings, parser support and evidence quality.

Incorrect Answers

A:

The stem asks about integrated GUI-based forensic case examination; fls enumerates file and directory names from supported filesystems, including deleted entries in many cases; the described operation is used for listing filesystem names and deleted entries. It does not by itself extract file contents; a determination about integrated GUI-based forensic case examination requires other support.

C:

In work concerning extracting file content using a metadata address, icat outputs file contents by filesystem metadata address, subject to allocation and recovery limits; the operation would not resolve integrated GUI-based forensic case examination. It differs from listing names or partition boundaries; the distinction leaves integrated GUI-based forensic case examination unsettled.

D:

A case involving signature-based file recovery without directory metadata might use this approach: photoRec searches media content for known file structures without depending on intact directory entries; the required result here is integrated GUI-based forensic case examination. Recovered filenames and original paths may be lost; it cannot replace proof about integrated GUI-based forensic case examination.

Question 462

An examiner using The Sleuth Kit first needs a list of deleted filesystem names, then needs the bytes of one file identified by metadata address. Which TWO commands complete those different tasks? Choose TWO.

  1. The Sleuth Kit fls
  2. The Sleuth Kit icat
  3. The Sleuth Kit mactime
  4. bulk_extractor
  5. ExifTool

Explanation

Correct Answers

A:

In this combined inquiry, fls enumerates file and directory names from supported filesystems, including deleted entries in many cases; it does not by itself extract file contents. This addresses listing filesystem names and deleted entries.

B:

In this combined inquiry, icat outputs file contents by filesystem metadata address, subject to allocation and recovery limits; it differs from listing names or partition boundaries. This addresses extracting file content using a metadata address.

Incorrect Answers

C:

In an inquiry concerning chronological output from a forensic body file, mactime sorts body-file records into a readable timeline and can filter date ranges; the scope does not extend to both listing filesystem names and deleted entries and extracting file content using a metadata address. It does not independently collect all event sources; that issue cannot settle both listing filesystem names and deleted entries and extracting file content using a metadata address.

D:

Even though the scenario needs both listing filesystem names and deleted entries and extracting file content using a metadata address, bulk_extractor scans content for recognizable features and reports offsets and contexts; the action relates to feature extraction from raw digital evidence. It can find leads in unallocated space but may not recover full files; this remains insufficient for both listing filesystem names and deleted entries and extracting file content using a metadata address.

E:

For the separate question of extraction of embedded media metadata, ExifTool reads a wide range of file metadata formats, including EXIF, and can output structured properties; the requested assessment of both listing filesystem names and deleted entries and extracting file content using a metadata address remains open. Metadata authenticity still requires corroboration; there is no direct finding about both listing filesystem names and deleted entries and extracting file content using a metadata address.

Question 463

A file's inode or metadata address is known, and the examiner needs its bytes extracted from a forensic image. Which TSK command fits?

  1. TestDisk
  2. The Sleuth Kit icat
  3. The Sleuth Kit fls
  4. ExifTool

Explanation

Correct Answer

B:

icat outputs file contents by filesystem metadata address, subject to allocation and recovery limits. It differs from listing names or partition boundaries.

Incorrect Answers

A:

With extracting file content using a metadata address as the investigative issue, testDisk analyzes partition structures and can assist recovery of lost partitions or boot sectors; the result would concern analysis and recovery of damaged partition structures. Changes should be made only to verified working copies under forensic procedures; this would not resolve extracting file content using a metadata address.

C:

The stem asks about extracting file content using a metadata address; fls enumerates file and directory names from supported filesystems, including deleted entries in many cases; the described operation is used for listing filesystem names and deleted entries. It does not by itself extract file contents; a determination about extracting file content using a metadata address requires other support.

D:

Instead of a method addressing extracting file content using a metadata address, ExifTool reads a wide range of file metadata formats, including EXIF, and can output structured properties; this one concerns extraction of embedded media metadata. Metadata authenticity still requires corroboration; it cannot independently determine extracting file content using a metadata address.

Question 464

A raw image may contain multiple partitions and gaps, and the investigator needs their offsets. Which TSK tool helps?

  1. The Sleuth Kit mmls
  2. The Sleuth Kit fls
  3. RegRipper
  4. bulk_extractor

Explanation

Correct Answer

A:

mmls displays volume-system partition layouts and unallocated regions. Those offsets can be passed to filesystem analysis commands.

Incorrect Answers

B:

For an analysis centered on listing filesystem names and deleted entries, fls enumerates file and directory names from supported filesystems, including deleted entries in many cases; the present need is partition offsets and unallocated disk regions. It does not by itself extract file contents; a different finding about partition offsets and unallocated disk regions is still needed.

C:

When the investigative task is structured examination of offline Windows registry hives, RegRipper uses plugins to extract and interpret selected Windows Registry data from offline hives; that differs from the question about partition offsets and unallocated disk regions. Plugin assumptions and OS version compatibility should be checked; that leaves partition offsets and unallocated disk regions unresolved.

D:

The current inquiry asks about partition offsets and unallocated disk regions; bulk_extractor scans content for recognizable features and reports offsets and contexts; this mechanism chiefly addresses feature extraction from raw digital evidence. It can find leads in unallocated space but may not recover full files; it cannot prove partition offsets and unallocated disk regions on its own.

Question 465

The lab has produced a body file and wants a chronological report of filesystem time attributes. Which utility should be used?

  1. The Sleuth Kit icat
  2. Autopsy
  3. The Sleuth Kit mactime
  4. The Sleuth Kit fls

Explanation

Correct Answer

C:

mactime sorts body-file records into a readable timeline and can filter date ranges. It does not independently collect all event sources.

Incorrect Answers

A:

The objective here is chronological output from a forensic body file; icat outputs file contents by filesystem metadata address, subject to allocation and recovery limits; the option would instead inform extracting file content using a metadata address. It differs from listing names or partition boundaries; it is not direct evidence of chronological output from a forensic body file.

B:

For a separate investigation of integrated GUI-based forensic case examination, Autopsy provides a graphical investigation environment built around filesystem and artifact analysis capabilities; that is not the determination of chronological output from a forensic body file in the stem. Results still depend on tool settings, parser support and evidence quality; the evidence still must speak to chronological output from a forensic body file.

D:

For questions about listing filesystem names and deleted entries, fls enumerates file and directory names from supported filesystems, including deleted entries in many cases; that differs from chronological output from a forensic body file. It does not by itself extract file contents; it provides no direct answer to chronological output from a forensic body file.

Question 466

Directory structures are badly damaged but identifiable media signatures remain. Which recovery program is designed for signature-based carving?

  1. PhotoRec
  2. The Sleuth Kit icat
  3. RegRipper
  4. Autopsy

Explanation

Correct Answer

A:

PhotoRec searches media content for known file structures without depending on intact directory entries. Recovered filenames and original paths may be lost.

Incorrect Answers

B:

The required finding is about signature-based file recovery without directory metadata; icat outputs file contents by filesystem metadata address, subject to allocation and recovery limits; this addresses the separate concern of extracting file content using a metadata address. It differs from listing names or partition boundaries; it does not by itself answer signature-based file recovery without directory metadata.

C:

Although the case asks about signature-based file recovery without directory metadata, RegRipper uses plugins to extract and interpret selected Windows Registry data from offline hives; the action instead concerns structured examination of offline Windows registry hives. Plugin assumptions and OS version compatibility should be checked; it does not establish signature-based file recovery without directory metadata.

D:

For an analysis centered on integrated GUI-based forensic case examination, Autopsy provides a graphical investigation environment built around filesystem and artifact analysis capabilities; the present need is signature-based file recovery without directory metadata. Results still depend on tool settings, parser support and evidence quality; a different finding about signature-based file recovery without directory metadata is still needed.

  1. The Sleuth Kit icat
  2. bulk_extractor
  3. ExifTool
  4. PhotoRec

Explanation

Correct Answer

B:

bulk_extractor scans content for recognizable features and reports offsets and contexts. It can find leads in unallocated space but may not recover full files.

Incorrect Answers

A:

The current inquiry asks about feature extraction from raw digital evidence; icat outputs file contents by filesystem metadata address, subject to allocation and recovery limits; this mechanism chiefly addresses extracting file content using a metadata address. It differs from listing names or partition boundaries; it cannot prove feature extraction from raw digital evidence on its own.

C:
