NEW QUESTION # 20
Which of the following tools helps a forensics investigator develop and test across multiple operating systems in a virtual machine for Mac and allows access to Microsoft Office for Windows?
Answer: B
Explanation:
A common requirement in macOS-focused forensic labs is the ability to runmultiple operating systemson a single Mac for controlled testing, malware detonation in a sandbox, reproduction of user activity, and validation of artifacts across platforms. This is typically achieved throughdesktop virtualization, where a hypervisor hosts guest operating systems (such as Windows and various Linux distributions) inside virtual machines.Parallels Desktop 16is a Mac virtualization solution built specifically to run Windows on macOS with strong integration features (such as shared clipboard, folder sharing, and "coherence" modes that allow Windows applications to appear alongside Mac applications). This capability aligns with the question's description: developing and testing across multiple OSs in VMs on a Mac and enabling use ofMicrosoft Office for Windowswithin that Windows guest environment.
The other tools do not fit.Riverbed ModelerandNetSimare primarilynetwork modeling/simulationtools used for network design and training, not desktop virtualization.Camtasiais used forscreen recording and video editing, which can support documentation but does not provide a VM environment. Therefore, the only option that directly provides cross-OS virtual machines on macOS and supports running Windows applications like Microsoft Office isParallels Desktop 16 (B).
NEW QUESTION # 21
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?
Answer: B
Explanation:
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).
NEW QUESTION # 22
Bob, a professional hacker, targeted an organization to launch attacks. Bob gathered information such as network topology and a list of live hosts. Based on the collected information, he launched further attacks over the organization's network.
Identify the type of network attack Bob initiated on the target organization in the above scenario.
Answer: B
Explanation:
The activity described-collectingnetwork topologydetails and compiling alist of live hosts-matches the reconnaissance phase commonly referred to asenumeration. In digital forensics and incident response documentation, enumeration is the systematic process of discovering and extracting information about a target environment to support later exploitation. It typically follows (or overlaps with) scanning and includes identifying active IP addresses, reachable systems, open ports/services, device roles, OS fingerprints, domain information, shared resources, user/group details, and routing or segmentation clues that reveal how the network is structured.
This information is then used to plan "further attacks," such as targeting exposed services, choosing exploit paths, locating high-value systems, and selecting lateral movement routes. From a forensic standpoint, enumeration attempts often leave traces in firewall logs, IDS alerts, and endpoint artifacts (e.g., bursts of connection attempts across many hosts/ports, ICMP echo sweeps, ARP discovery on local segments, and repeated DNS queries).
The other options do not fit:data modificationinvolves altering data integrity;session hijackingtargets active sessions/tokens; andbuffer overflowis an exploitation technique against vulnerable software, not the information-gathering step described. Therefore, the correct answer isEnumeration (B)
NEW QUESTION # 23
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?
Answer: B
Explanation:
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.
NEW QUESTION # 24
Bob, a forensic specialist at a newly established NGO, discovered a security loophole in the NGO's web application, which unintentionally reveals early enrolled NGO members' biodata to attackers. Bob immediately employed a content filtering mechanism to protect all the NGO's data sources and prevent further damage.
Identify the web application threat identified by Bob in the above scenario.
Answer: B
Explanation:
The scenario describes a web application thatunintentionally reveals sensitive member biodatato attackers.
This is a classic case ofinformation leakage, where confidential or private data becomes exposed due to poor access control, improper output handling, verbose error messages, misconfigured endpoints, insecure direct object references, or unintended exposure through pages, APIs, backups, or logs. In forensic and web security documentation, information leakage is defined by theunauthorized disclosure of data, even if the attacker does not alter the system. The key indicator here is that the application is "revealing" biodata-meaning confidentiality is breached.
Bob's response-using acontent filtering mechanism-also aligns with mitigating data exposure. Content filtering can prevent sensitive fields from being returned, mask personally identifiable information, restrict responses based on user role, and sanitize outputs before they leave the server.
The other options do not match the described impact.Buffer overflowis a low-level memory corruption vulnerability, typically associated with native code execution rather than accidental biodata exposure.
Authentication hijackinginvolves taking over sessions/credentials, andcookie poisoninginvolves manipulating cookie values to gain privileges or alter behavior-neither is explicitly indicated. Therefore, the identified threat isInformation leakage (B).
