問題 #45
Which of the following layers of the TCP/IP model includes protocols such as Frame Relay, SMDS, Fast Ethernet, SLIP, PPP, FDDI, ATM, Ethernet, and ARP to enable a machine to deliver the desired data to other hosts in the same network?
答案：B
解題說明：
The protocols listed-Frame Relay, SMDS, Fast Ethernet, SLIP, PPP, FDDI, ATM, Ethernet, and ARP- belong to the portion of the TCP/IP model responsible forlocal network deliveryand direct interaction with the physical media and link-layer addressing. In TCP/IP terminology, this is theNetwork Access layer(also called the Link layer or Network Interface layer). It combines functions that map closely to the OSIData LinkandPhysicallayers.
This layer is essential for delivering frames within the same network segment because it governs how devices access the medium (e.g., Ethernet), how frames are formatted and transmitted, and how hardware addressing works.ARP (Address Resolution Protocol)is especially important here: it resolvesIP addresses to MAC addressesso that an IP packet can be encapsulated into a link-layer frame and delivered to the correct local host or next-hop gateway. Technologies like PPP/SLIP support point-to-point links, while Frame Relay/ATM represent WAN/link technologies, all of which still sit under IP and provide the mechanisms for moving data across the immediate network path.
TheInternet layerhandles IP routing between networks, theTransport layerprovides end-to-end host communications (TCP/UDP), and theApplication layerprovides user protocols. Therefore, the correct layer isNetwork access layer (A).
問題 #46
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：B
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 #47
An organization decided to strengthen the security of its network by studying and analyzing the behavior of attackers. For this purpose, Steven, a security analyst, was instructed to deploy a device to bait attackers.
Steven selected a solution that appears to contain very useful information to lure attackers and find their locations and techniques.
Identify the type of device deployed by Steven in the above scenario.
答案：A
解題說明：
Ahoneypotis a deliberately deployed decoy system or service designed toattract attackersby appearing valuable or vulnerable, thereby enabling defenders to observe malicious behavior in a controlled manner.
Digital forensics and incident response references describe honeypots as tools forthreat intelligence and evidence collection, because they can record interaction details such as connection sources, exploited services, commands executed, malware dropped, and attempted privilege escalation. This directly matches the scenario: Steven deployed something that "appears to contain very useful information" tolure attackersand help identify theirlocations and techniques. Honeypots are typically instrumented with extensive logging and monitoring, making them especially useful for building timelines, extracting indicators of compromise, and understanding adversary tactics, techniques, and procedures.
The other options do not align with the "bait attackers" goal. AnIDSprimarily detects and alerts on suspicious activity but is not intended to impersonate a valuable target. Afirewallenforces access control rules to block
/allow traffic, not entice attackers. Arouterforwards packets and provides network connectivity; it is not a deception platform. Therefore, the device type described is aHoneypot (C).
問題 #48
Which of the following steps in forensic readiness planning provides a backup for future reference and assists in presenting evidence in a court of law?
答案：D
解題說明：
In forensic readiness planning, the goal is to ensure that when an incident occurs, the organization can collect, preserve, and present digital evidence in a manner that remainsreliable, repeatable, and legally defensible. A key requirement for courtroom acceptance is cleardocumentation-often referred to as proper documentation and chain-of-custody support-showing what actions were taken, by whom, when, using which tools, and under what conditions. Creating a defined process for documenting procedures ensures investigators consistently record acquisition steps, handling methods, hashing/verification results, storage locations, access history, and any changes in evidence possession. This documentation becomes a "backup" in the sense that it preserves institutional memory of the investigation steps, allowing future reviewers (auditors, opposing experts, courts) to reconstruct and validate what occurred even long after the incident.
While identifying potential evidence (B) and determining evidence sources (C) are important readiness tasks, they do not themselves create the structured record needed to defend evidence integrity. Keeping an incident response team ready (D) supports operational response, but does not directly ensure admissibility. Therefore, the step that provides future reference and supports court presentation isCreating a process for documenting the procedure (A).
問題 #49
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：B
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.
