問題 #11
Which of the following files belonging to the Extensible Storage Engine (ESE) stores the mail data in Microsoft Exchange Server?

答案：C

解題說明：
Microsoft Exchange Server stores mailbox contents (emails, attachments, folders, and related messaging objects) inside anESE (Extensible Storage Engine) databasethat uses the.edbfile format. In Exchange terminology this is theMailbox Database, and its primary persistent store is thedatabase .edb filealong with associated transaction logs that support write-ahead logging and recovery. From a forensic perspective, the.
edbfile is the central artifact because it contains the structured mailbox data that investigators analyze for message content, metadata (timestamps, sender/recipient fields, message IDs), and folder structure.
Among the options,Database.edbbest matches the Exchange ESE mailbox database file that stores mail data.
The other options are either generic or associated with different Microsoft messaging components:Mail.
MSMessageStorerelates to the Windows Mail/Modern Mail app storage model rather than Exchange Server's mailbox database, andWLCalendarStore.edbis commonly tied to Windows Live/Windows Essentials calendar or communications storage, not Exchange's server-side mailbox store.DataStore.edbis also used by other Windows services, but the recognized Exchange mailbox store is the.edb database file, makingDatabase.edb (D)the correct answer.


問題 #12
Sarah, a forensic investigator, is working on a criminal case. She was provided with all the suspect devices.
Sarah employs an imaging software tool for duplicating the original data from the suspect devices. However, the tool she employed failed to image the data as the suspect version of the drive was very old and incompatible with imaging software. Hence, Sarah used an alternative data acquisition technique and succeeded in imaging the data.
Which of the following types of data acquisition techniques did Sarah employ in the above scenario?

答案：C

解題說明：
The key detail is that Sarah'simaging softwarecould not acquire the device because the drive wasvery old and incompatiblewith the software-based approach. In such situations, forensic practice recommends switching to an acquisition method that isless dependent on the operating system or specific imaging application compatibility, while still producing a forensic-accurate duplicate.Bit-stream disk-to-diskacquisition (also called forensic cloning) creates asector-by-sectorcopy of the entire source drive directly onto another physical drive. This method is commonly performed using dedicated duplicators or hardware-assisted workflows that can interface with legacy media more reliably than certain disk-to-image software utilities.
Sparse acquisition would intentionally capture only selected portions of a disk (used to reduce time/storage), which does not fit the goal of "succeeded in imaging the data" after a failure due to incompatibility. Logical acquisition captures only active files/folders through the file system and is not the preferred alternative when full forensic imaging is required, especially in criminal cases. Bit-stream disk-to-image-file is still software
/container dependent and is essentially what failed initially. Therefore, the most appropriate alternative that explains success with an older incompatible drive isBit-stream disk-to-disk (D).


問題 #13
Which of the following acts was passed by the U.S. Congress in 2002 to protect investors from the possibility of fraudulent accounting activities by corporations?

答案：B

解題說明：
TheSarbanes-Oxley Act (SOX)was enacted by the U.S. Congress in2002in response to major corporate accounting scandals and was specifically designed toprotect investorsby improving the accuracy, reliability, and integrity of corporate disclosures and financial reporting. SOX strengthens governance and accountability by requiring executive management (notably the CEO and CFO) to certify the correctness of financial statements and by mandating stronger internal controls over financial reporting. From a digital forensics and compliance perspective, SOX is closely tied to the need for reliableaudit trails, properrecords retention, and demonstrable control over systems that store or process financial data. Investigators frequently rely on SOX- driven logging, access controls, and change management records to determine who accessed financial systems, what changes were made, and whether those actions align with authorized procedures.
The other options do not match the question's purpose or jurisdiction: theElectronic Communications Privacy Actaddresses interception and access to electronic communications,GDPRis an EU data protection regulation (not a 2002 U.S. act focused on investor protection), and "Information Privacy Act 2014" is not the 2002 U.S.
corporate anti-fraud legislation. Therefore, the correct answer isSarbanes-Oxley Act (SOX) (C).


問題 #14
Sam, a digital forensic expert, is working on a case related to file tampering in a system at the administrative department of an organization. In this process, Sam started performing the following steps to analyze the acquired data to draw conclusions related to the case.
1.Analyze the file content for data usage.
2.Analyze the date and time of file creation and modification.
3.Find the users associated with file creation, access, and file modification.
4.Determine the physical storage location of the file.
5.Generate a timeline.
6.Identify the root cause of the incident.
Identify the type of analysis performed by Sam in the above scenario.

答案：B

解題說明：
The listed actions describe theexamination and interpretation of acquired evidence, which aligns withdata analysisin the digital forensics investigation process. After collection and acquisition, examiners analyze evidence by validating what the data contains (file content and usage), interpretingMAC times(creation
/modification and related timestamps), attributing actions tousers and accounts(who created, accessed, or modified the file), and determiningwhere the file resides physically/logicallyon storage (path, volume, clusters
/blocks, and whether it appears in allocated/unallocated areas). Generating atimelineis a core analytical task used to correlate file events with system activity and other artifacts to reconstruct sequence and intent. Finally,
"identify the root cause of the incident" represents the analytical conclusion derived from correlating artifacts and timeline events.
The other choices do not match the described work.Search and seizureis the legal/field activity of locating and securing evidence sources, not interpreting artifacts.Reportingis the documentation phase after analysis, where findings and methods are written up.Case analysisis broader and can include overall strategy and interpretation, but the question's focus is explicitly on analyzing acquired data and producing forensic conclusions, which isdata analysis.


問題 #15
An investigator wants to extract information about the status of the network interface cards (NICs) in an organization's Windows-based systems. Identify the command-line utility that can help the investigator detect the network status.

答案：A

解題說明：
On Windows systems,ipconfigis the standard command-line utility used to display and troubleshootTCP/IP configurationand the operational status of network interfaces. From a forensic and incident-response perspective, it helps investigators quickly identify whether a NIC is enabled and configured, and it reveals key network parameters tied to "network status," such as theassigned IPv4/IPv6 addresses,subnet mask,default gateway, andDNS servers. Using variants likeipconfig /all, responders can also capture adapter-specific metadata includingMAC address (physical address), DHCP enablement, DHCP server, lease timestamps, and interface descriptions-useful for correlating an endpoint to switch-port logs, DHCP logs, and network monitoring data. This is often part of live triage because it documents the system's current connectivity and routing context at the time of seizure or investigation.
The other options are not appropriate for NIC status:PsLoggedOnreports logged-on users, andPsListenumerates running processes-both are Sysinternals tools focused on user/process state rather than network interface configuration.ifconfigis a UNIX/Linux command (and not the primary Windows utility), so it would not be the correct choice for Windows-based systems. Therefore,ipconfig (A)is correct.
