ECCouncil 312-49v11 (Computer Hacking Forensic Investigator) Practice Test 35

Question 340

A user opened a shortcut to a removable-drive document, and volume identifiers may remain. Which artifact should be examined?

  1. Web browser History database
  2. Browser cookies
  3. LNK shortcut files
  4. SRUM database

Explanation

Correct Answer

C:

LNK files can preserve target paths, volume metadata and timestamps from shortcut creation or updates. The target may no longer exist when the shortcut is parsed.

Incorrect Answers

A:

Instead of a method addressing shortcut target and volume context, browser history databases may record visited URLs, transition types and visit times, subject to private browsing and deletion behavior; this one concerns historical browser navigation records. They require profile-specific parsing; it cannot independently determine shortcut target and volume context.

B:

In work concerning stored web session state in a browser, cookies store site-associated state, sometimes including session identifiers and expiration metadata; the operation would not resolve shortcut target and volume context. Their presence does not conclusively establish the person who used a session; the distinction leaves shortcut target and volume context unsettled.

D:

The required finding is about shortcut target and volume context; the System Resource Usage Monitor database tracks resource and network usage attributed to applications and users where collected; this addresses the separate concern of Windows per-application usage records. Its data is aggregated and subject to retention limits; it does not by itself answer shortcut target and volume context.

Question 341

A directory was later deleted, but the investigation asks whether Explorer displayed it previously. Which Windows artifact is relevant?

  1. Prefetch files
  2. ShellBags
  3. Browser cookies
  4. Web browser History database

Explanation

Correct Answer

B:

ShellBags retain per-user folder view and navigation information, potentially including paths no longer present. They do not guarantee the user opened individual files.

Incorrect Answers

A:

The current inquiry asks about historical folder navigation in Explorer; prefetch metadata can include executable names, run-related times and referenced files, with version-specific details; this mechanism chiefly addresses Windows application execution traces. Its absence is not proof the program never executed; it cannot prove historical folder navigation in Explorer on its own.

C:

Even though the scenario needs historical folder navigation in Explorer, cookies store site-associated state, sometimes including session identifiers and expiration metadata; the action relates to stored web session state in a browser. Their presence does not conclusively establish the person who used a session; this remains insufficient for historical folder navigation in Explorer.

D:

For the separate question of historical browser navigation records, browser history databases may record visited URLs, transition types and visit times, subject to private browsing and deletion behavior; the requested assessment of historical folder navigation in Explorer remains open. They require profile-specific parsing; there is no direct finding about historical folder navigation in Explorer.

Question 342

Analysts want per-application network usage and resource accounting over time on Windows. Which artifact can assist?

  1. Amcache hive
  2. Browser cookies
  3. SRUM database
  4. Prefetch files

Explanation

Correct Answer

C:

The System Resource Usage Monitor database tracks resource and network usage attributed to applications and users where collected. Its data is aggregated and subject to retention limits.

Incorrect Answers

A:

For questions about Windows application metadata after file removal, amcache can contain application and executable metadata useful for program presence and execution-related analysis; that differs from Windows per-application usage records. Exact fields and evidentiary meaning vary by Windows version; it provides no direct answer to Windows per-application usage records.

B:

The stem asks about Windows per-application usage records; cookies store site-associated state, sometimes including session identifiers and expiration metadata; the described operation is used for stored web session state in a browser. Their presence does not conclusively establish the person who used a session; a determination about Windows per-application usage records requires other support.

D:

In work concerning Windows application execution traces, prefetch metadata can include executable names, run-related times and referenced files, with version-specific details; the operation would not resolve Windows per-application usage records. Its absence is not proof the program never executed; the distinction leaves Windows per-application usage records unsettled.

Question 343

A user denies navigating to a suspicious URL and the examiner needs browser visit artifacts. Which source is most direct?

  1. ShellBags
  2. Shimcache AppCompatCache
  3. Amcache hive
  4. Web browser History database

Explanation

Correct Answer

D:

Browser history databases may record visited URLs, transition types and visit times, subject to private browsing and deletion behavior. They require profile-specific parsing.

Incorrect Answers

A:

For an analysis centered on historical folder navigation in Explorer, ShellBags retain per-user folder view and navigation information, potentially including paths no longer present; the present need is historical browser navigation records. They do not guarantee the user opened individual files; a different finding about historical browser navigation records is still needed.

B:

When the investigative task is compatibility-cache references to executables, shimcache records compatibility-related file metadata; path presence alone is not a universal execution indicator; that differs from the question about historical browser navigation records. Parsing and time semantics depend on Windows version; that leaves historical browser navigation records unresolved.

C:

The current inquiry asks about historical browser navigation records; amcache can contain application and executable metadata useful for program presence and execution-related analysis; this mechanism chiefly addresses Windows application metadata after file removal. Exact fields and evidentiary meaning vary by Windows version; it cannot prove historical browser navigation records on its own.

Question 344

An examiner investigates whether a web session token or tracking identifier existed in a user profile. Which artifact is relevant?

  1. Browser cookies
  2. Shimcache AppCompatCache
  3. ShellBags
  4. Windows thumbnail cache

Explanation

Correct Answer

A:

Cookies store site-associated state, sometimes including session identifiers and expiration metadata. Their presence does not conclusively establish the person who used a session.

Incorrect Answers

B:

With stored web session state in a browser as the investigative issue, shimcache records compatibility-related file metadata; path presence alone is not a universal execution indicator; the result would concern compatibility-cache references to executables. Parsing and time semantics depend on Windows version; this would not resolve stored web session state in a browser.

C:

For questions about historical folder navigation in Explorer, ShellBags retain per-user folder view and navigation information, potentially including paths no longer present; that differs from stored web session state in a browser. They do not guarantee the user opened individual files; it provides no direct answer to stored web session state in a browser.

D:

The stem asks about stored web session state in a browser; thumbnail cache databases hold generated previews for media and documents, depending on configuration; the described operation is used for cached visual preview of a file. They may survive changes to the underlying original file; a determination about stored web session state in a browser requires other support.

Question 345

A deleted picture appears to have been previewed in Explorer, and a miniature rendering may survive. Which artifact can provide a lead?

  1. ShellBags
  2. Windows thumbnail cache
  3. SRUM database
  4. Prefetch files

Explanation

Correct Answer

B:

Thumbnail cache databases hold generated previews for media and documents, depending on configuration. They may survive changes to the underlying original file.

Incorrect Answers

A:

The required finding is about cached visual preview of a file; ShellBags retain per-user folder view and navigation information, potentially including paths no longer present; this addresses the separate concern of historical folder navigation in Explorer. They do not guarantee the user opened individual files; it does not by itself answer cached visual preview of a file.

C:

For an analysis centered on Windows per-application usage records, the System Resource Usage Monitor database tracks resource and network usage attributed to applications and users where collected; the present need is cached visual preview of a file. Its data is aggregated and subject to retention limits; a different finding about cached visual preview of a file is still needed.

D:

When the investigative task is Windows application execution traces, prefetch metadata can include executable names, run-related times and referenced files, with version-specific details; that differs from the question about cached visual preview of a file. Its absence is not proof the program never executed; that leaves cached visual preview of a file unresolved.

Question 346

Windows Security auditing was enabled for logons and process creation. Which TWO event IDs respectively help establish a successful sign-in and the later launch of an executable? Choose TWO.

  1. Event 7045
  2. Event 4624
  3. Event 1102
  4. Sysmon Event 1
  5. Event 4688

Explanation

Correct Answers

B:

In this combined inquiry, security event 4624 records successful logons when audited, with logon type and account context; it does not by itself show which commands the session performed. This addresses a Windows successful logon record.

E:

In this combined inquiry, event 4688 records process creation under appropriate audit settings; command-line inclusion requires its own policy configuration; execution evidence depends on what was enabled at the time. This addresses Windows audited process creation.

Incorrect Answers

A:

For the separate question of installation of a Windows service, service Control Manager event 7045 can document creation of a service with associated properties; the requested assessment of both a Windows successful logon record and Windows audited process creation remains open. Investigators should correlate it with executable and privilege evidence; there is no direct finding about both a Windows successful logon record and Windows audited process creation.

C:

For a separate investigation of clearing of the Windows Security log, event 1102 records clearing of the Security audit log and may include the subject account; that is not the determination of both a Windows successful logon record and Windows audited process creation in the stem. External log forwarding helps preserve surrounding context if local history is missing; the evidence still must speak to both a Windows successful logon record and Windows audited process creation.

D:

With both a Windows successful logon record and Windows audited process creation as the investigative issue, Sysmon Event ID 1 captures process creation with enriched context when Sysmon is installed and configured; the result would concern Sysmon process creation details. It is distinct from Windows native Security 4688; this would not resolve both a Windows successful logon record and Windows audited process creation.

Question 347

A domain-joined workstation shows repeated password failures and investigators need the relevant Security events. Which ID is used?

  1. Sysmon Event 1
  2. Sysmon Event 3
  3. Event 1102
  4. Event 4688
  5. Event 4625

Explanation

Correct Answer

E:

Event 4625 represents failed logon attempts where auditing provides the event. Status and substatus fields may help distinguish causes and logon paths.

Incorrect Answers

A:

In work concerning Sysmon process creation details, Sysmon Event ID 1 captures process creation with enriched context when Sysmon is installed and configured; the operation would not resolve a Windows failed logon record. It is distinct from Windows native Security 4688; the distinction leaves a Windows failed logon record unsettled.

B:

A case involving Sysmon process-to-network connection association might use this approach: Sysmon Event ID 3 describes network connections associated with processes when configured; the required result here is a Windows failed logon record. It provides host attribution but no complete application payload; it cannot replace proof about a Windows failed logon record.

C:

The required finding is about a Windows failed logon record; event 1102 records clearing of the Security audit log and may include the subject account; this addresses the separate concern of clearing of the Windows Security log. External log forwarding helps preserve surrounding context if local history is missing; it does not by itself answer a Windows failed logon record.

D:

Although the case asks about a Windows failed logon record, event 4688 records process creation under appropriate audit settings; command-line inclusion requires its own policy configuration; the action instead concerns Windows audited process creation. Execution evidence depends on what was enabled at the time; it does not establish a Windows failed logon record.

Question 348

A sensitive account signs in and receives special privileges associated with the new session. Which event identifies that assignment?

  1. Event 1102
  2. PowerShell 4104
  3. Event 4672
  4. Event 4688

Explanation

Correct Answer

C:

Security event 4672 indicates special privileges assigned to a new logon under audit. It is not itself evidence that each privilege was exercised.

Incorrect Answers

A:

In an inquiry concerning clearing of the Windows Security log, event 1102 records clearing of the Security audit log and may include the subject account; the scope does not extend to special privileges assigned at logon. External log forwarding helps preserve surrounding context if local history is missing; that issue cannot settle special privileges assigned at logon.

B:

Even though the scenario needs special privileges assigned at logon, PowerShell event 4104 can record executed script block text, with coverage depending on policy and execution context; the action relates to logged PowerShell script content. It can reveal behavior not evident from a process name alone; this remains insufficient for special privileges assigned at logon.

D:

The objective here is special privileges assigned at logon; event 4688 records process creation under appropriate audit settings; command-line inclusion requires its own policy configuration; the option would instead inform Windows audited process creation. Execution evidence depends on what was enabled at the time; it is not direct evidence of special privileges assigned at logon.

Question 349

Investigators need process creation events with parent and command-line fields when configured. Which Windows Security event is used?

  1. Event 4624
  2. Event 7045
  3. Event 4688
  4. Event 1102

Explanation

Correct Answer

C:

Event 4688 records process creation under appropriate audit settings; command-line inclusion requires its own policy configuration. Execution evidence depends on what was enabled at the time.

Incorrect Answers

A:

The stem asks about Windows audited process creation; security event 4624 records successful logons when audited, with logon type and account context; the described operation is used for a Windows successful logon record. It does not by itself show which commands the session performed; a determination about Windows audited process creation requires other support.

B:

Instead of a method addressing Windows audited process creation, service Control Manager event 7045 can document creation of a service with associated properties; this one concerns installation of a Windows service. Investigators should correlate it with executable and privilege evidence; it cannot independently determine Windows audited process creation.

D:

A case involving clearing of the Windows Security log might use this approach: event 1102 records clearing of the Security audit log and may include the subject account; the required result here is Windows audited process creation. External log forwarding helps preserve surrounding context if local history is missing; it cannot replace proof about Windows audited process creation.

Question 350

A local Windows Security log was cleared before forensic capture. Which event can help identify that action?

  1. Event 1102
  2. Sysmon Event 3
  3. Event 4624
  4. PowerShell 4104

Explanation

Correct Answer

A:

Event 1102 records clearing of the Security audit log and may include the subject account. External log forwarding helps preserve surrounding context if local history is missing.

Incorrect Answers

B:

The current inquiry asks about clearing of the Windows Security log; Sysmon Event ID 3 describes network connections associated with processes when configured; this mechanism chiefly addresses Sysmon process-to-network connection association. It provides host attribution but no complete application payload; it cannot prove clearing of the Windows Security log on its own.

C:

In an inquiry concerning a Windows successful logon record, security event 4624 records successful logons when audited, with logon type and account context; the scope does not extend to clearing of the Windows Security log. It does not by itself show which commands the session performed; that issue cannot settle clearing of the Windows Security log.

D:

Even though the scenario needs clearing of the Windows Security log, PowerShell event 4104 can record executed script block text, with coverage depending on policy and execution context; the action relates to logged PowerShell script content. It can reveal behavior not evident from a process name alone; this remains insufficient for clearing of the Windows Security log.
