質問 # 30
Which of the following measures is defined as the time to move read or write disc heads from one point to another on the disk?
正解：C
解説：
Seek timeis the specific performance measure that describes how long a hard disk drive's actuator takes tomove the read/write heads across the plattersfrom the current track (cylinder) to the target track where the requested data resides. In traditional magnetic HDDs, the heads must be physically repositioned before any sector can be read or written, making seek time a core component of mechanical latency.
Digital forensics materials emphasize understanding this distinction because HDD mechanical behavior affectsacquisition duration, the feasibility of repeated scans, and why imaging or carving operations can take longer on fragmented media. It also helps explain why solid-state drives (SSDs), which have no moving heads, do not have seek time in the same sense and therefore behave differently during large-scale reads.
The other choices are broader or unrelated:access timetypically refers to thetotal time to retrieve data, commonly combiningseek time + rotational latency + transfer time.Delay timeis not the standard term for head movement in disk performance definitions.Mean timeis incomplete as written and is usually part of reliability metrics like mean time between failures, not head positioning. Therefore, the correct measure for head movement time isSeek time (C).
質問 # 31
Which of the following hives in the Windows Registry hierarchical database is volatile in nature and contains file-extension association information and programmatic identifier (ProgID), Class ID (CLSID), and Interface ID (IID) data?
正解：D
解説：
HKEY_CLASSES_ROOT (HKCR)is the Windows Registry location that storesfile-association and COM registration data, including mappings forfile extensions(e.g.,.docx) toProgIDs, and COM object identifiers such asCLSIDand interface-related identifiers likeIID. In forensic examinations, HKCR is frequently consulted to determine which application is registered to open a specific file type, to identify COM objects that may enable persistence or abuse (e.g., through COM hijacking), and to correlate suspicious registry-based execution mechanisms with installed software.
HKCR is often described asvolatile in naturebecause it is not a single standalone hive file stored independently in the same way as SAM or SYSTEM; instead, it is amerged, runtime viewcreated by the OS primarily fromHKLM\Software\Classes(machine-wide registrations) andHKCU\Software\Classes(per-user overrides). This means what you see under HKCR can vary depending on the current user context and system state, and the effective associations/registrations may change when software is installed, updated, or when per- user settings override machine defaults.
The other options represent different scopes: HKLM is system configuration, HKCU is user profile configuration, and HKCC reflects the current hardware profile-not the primary COM/file association repository.
質問 # 32
Which of the following MAC forensic data components saves file information and related events using a token with a binary structure?
正解：A
解説：
On macOS, theBasic Security Module (BSM)provides the system'saudit framework, which records security- relevant activity such asfile access, process execution, authentication events, privilege changes, and other system calls. A key forensic characteristic of BSM auditing is that events are written asbinary audit records composed of "tokens."Each token represents a structured piece of the event (for example: subject/user identity, process ID, command arguments, path, return value, timestamps), and tokens are assembled into complete audit records. Because these audit logs arebinary and tokenized, they are compact, consistent, and designed for reliable parsing and evidentiary reconstruction-important when building timelines of file- related actions and attributing them to specific users and processes.
The other options do not match the "binary token" description.Command-line inputsmay be stored in shell history files but are plain text and not tokenized binary audit records.User accountartifacts (e.g., directory services, plist files) describe identities and settings, not tokenized event logs.Kexts(kernel extensions) are drivers/modules; while they can affect system behavior, they are not the macOS component that stores file
/event records in a binary token format. Therefore, the correct answer isBasic Security Module (C).
質問 # 33
Sam is working as a loan agent for a financial institution. He frequently receives a number of emails from clients providing their personal details for loan approval. As these emails contain sensitive data, Sam had set up a feature that directly downloads the emails on his device without storing a copy on the mail server. Which of the following protocols provides the above-discussed email features?
正解：C
解説：
The scenario describes an email-retrieval configuration in which messages aredownloaded to a client device andnot retained on the server. This behavior aligns withPOP3 (Post Office Protocol v3), a legacy but widely referenced mail access protocol that retrieves email from a server mailbox to a local client. In standard POP3 operation, the client authenticates to the mail server, issues retrieval commands (e.g., to list and download messages), and may then issue a delete command so that downloaded messages are removed from the server mailbox. Digital forensics references commonly contrast POP3 with IMAP:IMAP is designed for server-side mailbox synchronization and typically leaves mail stored on the server, whereas POP3 is oriented towardclient-side storageand supports workflows where server copies are not preserved after download. The other options are unrelated to email retrieval:SHA-1is a cryptographic hash function used for integrity checks,ICMPsupports network diagnostics and control messaging, andSNMPis used for network device management and monitoring. From an investigative standpoint, POP3 usage can reduce server-resident evidence and shift evidentiary value tolocal artifacts(mail client databases, cache, OS traces, backups), which is consistent with the intent described in the question.
質問 # 34
Alice and John are close college friends. Alice frequently sends emails to John attaching her pics with friends.
One day, Alice sent an email to John describing all the details related to the final year project without specifying the actual purpose. John missed the message as he frequently receives emails from her and did not arrive for a project seminar.
Which of the following email fields could Alice have used in the above scenario to highlight the importance of the email?
正解：B
解説：
TheSubjectfield is the primary email header element used to communicate thepurpose and urgencyof a message at a glance. Digital forensics training emphasizes that email messages consist ofheaders(routing and descriptive metadata) and abody(content). Among user-visible header fields, the Subject line is specifically intended to summarize what the email is about, helping recipients prioritize and correctly interpret the message without opening it. In the scenario, John routinely receives casual emails from Alice (often with pictures). When Alice sent a project-related email "without specifying the actual purpose," John treated it like routine mail and overlooked its significance. A clear, descriptive subject such as "Final Year Project Seminar
- Attendance Required" would have flagged the message as time-sensitive and different from her usual emails, reducing the chance it would be missed.
The other options do not serve this purpose.Dateis automatically assigned and mainly supports ordering and timeline reconstruction rather than highlighting importance.CcandBcccontrol who receives copies and can affect visibility or secrecy, but they do not summarize intent for the recipient. Therefore, the field best suited to highlight importance isSubject (A).
