NEW QUESTION # 38
Given below are different steps involved in event correlation.
Event masking
Event aggregation
Root cause analysis
Event filtering
Identify the correct sequence of steps involved in event correlation.
Answer: D
Explanation:
In event correlation (as applied in SOC/SIEM-driven investigations), the workflow typically starts byreducing complexityandnormalizing what "one incident" looks likebefore attempting conclusions about causality.Event aggregation (2)is performed early to combine multiple low-level, related events (for example repeated authentication failures, repeated firewall denies, or multiple IDS hits for the same signature) into higher-level
"grouped" records. This prevents analysts from treating every raw log line as a separate incident and makes correlation computationally and operationally feasible.
Next,event masking (1)suppresses events that are already known to be irrelevant or repetitive in a way that does not add investigative value (for example, routine scheduled scans, approved admin tools, or duplicate alerts already represented in the aggregated set). After masking,event filtering (4)further removes remaining noise using rules, thresholds, whitelists, time windows, or relevance criteria (scope, asset criticality, and known-benign sources), leaving a cleaner dataset that represents probable security-relevant activity.
Only after the dataset is consolidated and noise-reduced doesroot cause analysis (3)become reliable, because RCA depends on a clear chain of correlated events to identify the initiating action and propagation path.
Hence the correct sequence is2 # 1 # 4 # 3 (Option B).
NEW QUESTION # 39
In which of the following malware distribution techniques does the attacker use tactics such as keyword stuffing, doorway pages, page swapping, and adding unrelated keywords to improve the search-engine ranking of their malware pages?
Answer: C
Explanation:
The technique described-keyword stuffing, doorway pages, page swapping, and inserting unrelated high- traffic keywords-matchesblack-hat search-engine optimization (SEO), often calledSEO poisoningin digital forensics and threat intelligence materials. In this distribution method, attackers manipulate search engine ranking algorithms so that malicious or malware-hosting pages appear near the top of search results for popular queries (breaking news, software downloads, trending events, adult content, etc.). Doorway pages are created to rank well for specific terms and then funnel victims to malicious landing pages. Page swapping (or
"bait-and-switch") occurs when a page is optimized and indexed as benign content, but later replaced or dynamically served as malicious content once it has gained ranking and trust signals. Keyword stuffing and unrelated keyword injection further exploit ranking heuristics by artificially increasing perceived relevance.
From a forensic perspective, black-hat SEO campaigns often leave artifacts such as compromised websites with injected spam links, abnormal redirect chains, cloaking behavior (different content for crawlers vs.
users), and malicious scripts or exploit kit references. The other options do not primarily rely on search ranking manipulation: drive-by downloads are about silent exploitation on visit, spearphishing relies on targeted messaging, and clickjacking tricks users into unintended clicks. Hence,Black-hat search-engine optimization (C)is correct.
NEW QUESTION # 40
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.
Answer: C
Explanation:
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.
NEW QUESTION # 41
Which of the following file systems is developed by Apple to support Mac OS in its proprietary Macintosh system and replace the Macintosh File System (MFS)?
Answer: B
Explanation:
Apple's original Macintosh computers initially usedMFS (Macintosh File System), which had important limitations, including a relatively flat directory model and constraints that became problematic as storage sizes and file organization needs grew. To address these limitations, Apple introducedHFS (Hierarchical File System)-explicitly designed to replace MFS and provide a truehierarchical directory structure(folders within folders), improved metadata handling, and better scalability for the Macintosh platform. From a digital forensics perspective, this historical transition matters because examiners may encounter legacy Macintosh media or disk images where understanding the file system family helps interpret catalog structures, allocation behavior, and metadata artifacts.
The other options do not fit the "replace MFS" requirement.NTFSis Microsoft's Windows file system.APFS (Apple File System)is Apple's modern file system introduced much later (primarily for SSDs, with features like snapshots and strong encryption support) and it replaced HFS+ in newer macOS versions-not MFS.
Filesystem Hierarchy Standard (FHS)is a UNIX/Linux directory layout standard, not a Macintosh disk file system. Therefore, the Apple-developed file system that replaced MFS isHierarchical File System (HFS), which corresponds toOption D.
NEW QUESTION # 42
Below is the syntax of a command-line utility that displays active TCP connections and ports on which the computer is listening.
netstat [-a] [-e] [-n] [-o] [-p Protocol] [-r] [-s] [Interval]
Identify the netstat parameter that displays active TCP connections and includes the process ID (PID) for each connection.
Answer: B
Explanation:
In Windows forensics and incident response, investigators often need to linknetwork activity(remote IPs, ports, connection states) to theresponsible processto determine whether traffic is legitimate or associated with malware, unauthorized tools, or data exfiltration. The Windowsnetstatutility can enumerate current TCP connections and listening ports, but the key flag that enables attribution to a running program is-o. The-o parameter instructs netstat to include theOwning Process ID (PID)with each connection or listening socket.
Once the PID is known, examiners can correlate it with process listings (e.g., Task Manager,tasklist, memory forensics output) to identify the executable name, path, user context, and parent process-critical steps in reconstructing attacker behavior and persistence.
The other options do not provide PID mapping:-nshows addresses and ports in numeric form (useful for speed and to avoid DNS lookups),-adisplays all connections and listening ports but without PID attribution by itself, and-sshows protocol statistics rather than per-connection ownership. Therefore, the parameter that shows active connectionsandincludes the PID for each is[-o](Option C).
