An IT technician discovers a corporate workstation actively communicating with a known malicious command-and-control server on the internet. To follow proper CompTIA incident response guidelines and preserve evidence integrity, in what order should the technician execute the following actions?

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct order of incident response and evidence preservation steps is: 1) Report the security incident immediately to the designated incident response team and management, 2) Isolate the workstation from the network by disconnecting the network cable and disabling Wi-Fi, 3) Capture the volatile system memory (RAM) while the machine remains powered on, and 4) Fill out a chain of custody log and place the seized physical storage drive into a tamper-evident anti-static bag.
Standard operational procedures specify that security incidents must first be reported to proper authorities. Next, the technician must isolate the compromised system from the network to stop active communication without powering down the machine. Once isolated, volatile memory (RAM) must be collected before system state changes. Finally, chain of custody logs are filled out as physical evidence is packaged and handed off.

Adım Adım Çözüm

1
Report the incident through proper organizational escalation channels.
The incident handling protocol is officially initiated with appropriate management awareness.
Reporting ensures that incident response procedures begin promptly and authorization is granted for further intervention.
2
Isolate the compromised system from local and wide area networks.
Active command-and-control traffic is severed without shutting down the system.
Immediate containment protects other network assets from infection and halts data exfiltration.
3
Perform volatile evidence capture (RAM collection).
Volatile artifacts like running processes, decrypted contents, and socket details are saved.
RAM is highly volatile and must be acquired while the system is live before non-volatile drives are removed or powered off.
4
Complete chain of custody documentation and secure physical evidence.
Legal defensibility and evidence tracking are established with verified timestamps and signatures.
Chain of custody forms account for evidence possession, transfers, and secure physical storage.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The proper troubleshooting order from least invasive to most invasive is: 1) Force close the application, 2) Restart (soft reset) the mobile device, 3) Install application and OS updates, 4) Reinstall the application, and 5) Perform a factory reset.
CompTIA troubleshooting methodology dictates progressing from the least disruptive action to the most disruptive action. Force closing the application is the quickest, least invasive step. If the problem persists, soft resetting the device clears shared system memory. Installing updates fixes software bugs. Reinstalling the app replaces corrupted files, and performing a factory reset is the final, most invasive step.

Adım Adım Çözüm

1
Terminate the affected application process.
Clears transient application lockups without impacting other services or device uptime.
Always begin troubleshooting at the least invasive layer closest to the problem.
2
Restart the operating system (soft reset).
Flushes system memory and restarts system services.
If force quitting fails, restarting the device resolves lower-level OS memory leaks or stuck background tasks.
3
Update software packages (app and OS).
Applies developer bug fixes and system optimization patches.
Ensures the issue is not caused by a known code bug before modifying application installations.
4
Remove and reinstall the application.
Replaces app binaries and refreshes local configuration stores.
More invasive step that clears persistent app-specific file corruption.
5
Execute a factory reset.
Wipes all local data and returns OS to default clean state.
Most invasive measure, reserved as a last resort when OS corruption or system-wide failure persists.

A user's workstation is assigned a static IP address of 192.168.4.15/24192.168.4.15/24. The user can successfully ping other local computers on the 192.168.4.0/24192.168.4.0/24 network segment, but cannot reach external internet addresses such as 1.1.1.11.1.1.1 by IP address. Other devices on the same local subnet can access external networks without issue. Which of the following network settings is most likely missing or misconfigured on the workstation?

Cevabı ve açıklamayı göster

Cevap: Default Gateway

Cevap

The Default Gateway setting is missing or misconfigured on the workstation.
The default gateway serves as the access point or router interface that forwards packets from the local subnet to external networks. Because the workstation can communicate with devices on its own subnet (192.168.4.0/24192.168.4.0/24) but cannot route traffic to remote IP addresses such as 1.1.1.11.1.1.1, the missing or incorrect Default Gateway address is the root cause.

Adım Adım Çözüm

1
Analyze local vs. remote network connectivity results
Successful local pings confirm Layer 1 and Layer 2 network access as well as correct local subnet IP configuration (192.168.4.15/24192.168.4.15/24).
Traffic staying within the 192.168.4.0/24192.168.4.0/24 network does not require a router.
2
Evaluate why direct IP requests to remote destinations (1.1.1.11.1.1.1) fail
Destinations outside the local subnet require packets to be forwarded to a local router (the default gateway).
If the default gateway IP is omitted or incorrectly set, the workstation cannot route packets outside 192.168.4.0/24192.168.4.0/24.

A desktop technician is servicing an electrophotographic (EP) laser printer that produces printed pages where toner is clearly visible and correctly positioned, but it easily smudges and wipes off the paper surface when touched. The technician has already verified that the paper type matches printer driver specifications and replaced the toner cartridge without resolving the issue. Which component is most likely failing to operate properly?

Cevabı ve açıklamayı göster

Cevap: Fuser assembly

Cevap

The fuser assembly is responsible for applying heat and pressure to permanently bond toner to paper fibers.
The fuser assembly uses intense heat and mechanical pressure to melt the plastic resin inside toner powder, permanently bonding it to the paper fibers. When the heating lamp or pressure roller fails, toner remains resting loosely on top of the paper, leading to severe smudging when touched.

Adım Adım Çözüm

1
Analyze symptom details from the scenario
Toner prints in the correct location but smudges easily off the page upon touch.
This indicates successful image development and transfer, but a failure during the bonding/fusing phase.
2
Evaluate the function of electrophotographic (EP) components
The fuser assembly operates at high temperatures (approx. 180°C–200°C) with pressure rollers to melt toner resin into the paper.
If the heating element or pressure rollers in the fuser malfunction, toner stays un-fused on the surface.
3
Determine the necessary repair action
Replace the fuser assembly (or maintenance kit containing the fuser).
Replacing the fuser restores proper heat and pressure application.

Cevap: M.2 solid-state drives with M-key edge connectors can utilize up to four PCIe lanes for high-throughput NVMe protocol storage.; SATA Revision 3.0 interfaces cap theoretical maximum throughput for connected storage drives at 6 Gbps.

Cevap

M.2 SSDs utilizing M-key pin configurations support up to four PCIe lanes for NVMe storage, and SATA Revision 3.0 specifies a maximum theoretical data transfer rate of 6 Gbps.
M.2 drives keyed with M-key edge pinouts accommodate up to four PCIe lanes (PCIe x4), which provides the bus bandwidth necessary for NVMe performance. Furthermore, SATA Revision 3.0 is standardized at a maximum interface data rate of 6 Gbps.

Adım Adım Çözüm

1
Evaluate M.2 physical keying standards and bus lane support.
M-key M.2 drives use pins 59-66 and support PCIe x4, whereas B-key drives use pins 12-19 and support up to PCIe x2 or SATA speeds.
Correctly matching the M.2 keying format to bus lanes ensures maximum available throughput for high-performance storage.
2
Analyze standard SATA controller protocol bandwidth limitations.
SATA Revision 3.0 provides a maximum bus speed limit of 6 Gbps.
Understanding interface limits prevents bottlenecking expectations when specifying drive speeds.
3
Distinguish between physical M.2 form factors and underlying logical protocols.
Inserting a SATA-based M.2 drive into an M.2 slot will not increase its throughput to NVMe levels because the drive's controller remains bound by SATA protocol constraints.

Cevap

The administrator must encrypt cardholder and personal data both at rest and in transit, and establish automated technical workflows to erase customer personal data upon valid GDPR right-to-be-forgotten requests.
The correct operational practices are applying strong cryptographic encryption to cardholder data and PII at rest and in transit, and setting up workflows to permanently erase EU customer data upon request under GDPR. PCI-DSS mandates encryption for cardholder data across storage and public network transmissions, while GDPR enforces technical data security (Article 32) and data erasure rights (Article 17).

Adım Adım Çözüm

1
Analyze regulatory scope for PCI-DSS data protection requirements.
PCI-DSS requires safeguarding Cardholder Data (CHD) through robust encryption during storage and transit, while explicitly banning the retention of Sensitive Authentication Data (SAD/CVV) after authorization.
Protecting cardholder data limits exposure to credit card fraud and maintains compliance with payment processor frameworks.
2
Analyze regulatory scope for GDPR data subject rights and storage limitation.
GDPR requires pseudonymization/encryption of PII, adherence to storage minimization (retaining data no longer than necessary), and honoring data erasure (right to be forgotten) requests.
EU residents maintain legal ownership of their personal data rights under GDPR standards.
3
Select valid operational controls matching both regulations.
Implementing strong encryption for CHD/PII at rest and in transit, alongside automated data erasure procedures, fulfills both compliance directives.
These controls directly satisfy PCI-DSS encryption requirements and GDPR privacy rights.

Cevabı ve açıklamayı göster

Cevap: Select SO-DIMM modules specifically designed for smaller mobile form-factor slots.; Install matching memory modules into designated color-coded or alternating slots corresponding to separate memory channels.

Cevap

The technician must select SO-DIMM modules to match the physical laptop form factor and install matching modules across distinct designated memory channels to enable multi-channel performance.
Mobile systems require SO-DIMM form-factor modules due to physical space constraints within the laptop chassis. Additionally, to take advantage of multi-channel architecture (such as dual-channel mode), modules of matching specifications must be installed in slots assigned to separate memory channels.

Adım Adım Çözüm

1
Identify the physical form factor required by the system chassis.
Laptops use SO-DIMM (Small Outline Dual In-line Memory Module) form factors, whereas desktop computers use full-sized DIMMs.
Full-sized DIMMs cannot physically fit into laptop memory slots.
2
Determine the proper slot population scheme for multi-channel memory performance.
Modules must be placed into slots designated for Channel A and Channel B (often alternating slots or specific pairing configurations as detailed in motherboard specs).
Installing modules on separate channels allows the memory controller to access both modules simultaneously, maximizing memory throughput.

A system technician builds a compact workstation using a motherboard equipped with two M.2 storage slots. Slot 1 is connected directly to the CPU and supports NVMe PCIe SSDs. Slot 2 is routed through the chipset and is specified as supporting M.2 SATA drives only. The technician installs a new M.2 NVMe PCIe 4.0 drive into Slot 2. Upon powering on the system and entering the UEFI/BIOS setup, the newly installed SSD is not recognized. Which of the following is the most likely cause of this detection failure?

Cevabı ve açıklamayı göster

Cevap: The M.2 slot is wired strictly for the SATA protocol, preventing an NVMe PCIe drive from communicating with the host controller.

Cevap

The M.2 slot is wired strictly for the SATA protocol, preventing an NVMe PCIe drive from communicating with the host controller.
Although M.2 SSDs share a common form factor, individual M.2 slots on a motherboard may support SATA signaling, PCIe signaling, or both. Inserting a PCIe NVMe drive into an M.2 slot that supports only the SATA protocol prevents the system from establishing a communication link, rendering the SSD unrecognized in the system setup.

Adım Adım Çözüm

1
Analyze the physical and protocol specifications of the motherboard slot.
Slot 2 supports M.2 SATA protocol only.
The host interface dictates which communication protocol (SATA vs PCIe/NVMe) can be used by installed storage devices.
2
Compare the installed drive's protocol requirement with the slot's capability.
An NVMe PCIe SSD relies on PCIe lanes, whereas the slot only provides SATA signaling lines.
If an NVMe drive is placed into a SATA-only slot, the controller cannot establish a PCIe link, causing the drive to remain undetectable in UEFI/BIOS.

While performing routine maintenance on a system administrator's workstation, a technician notices an unauthorized interactive remote shell executing administrative scripts in real time. The workstation contains volatile memory data critical for the incident investigation. Which action should the technician take FIRST to contain the threat while preserving digital evidence integrity?

Cevabı ve açıklamayı göster

Cevap: Disconnect the network interfaces to isolate the workstation while leaving the system powered on.

Cevap

Disconnect the network interfaces to isolate the workstation while leaving the system powered on.
Isolating network interfaces (such as unplugging the Ethernet cable or disabling Wi-Fi) immediately halts remote command execution and data exfiltration without losing RAM contents. Keeping the system powered on preserves volatile forensic artifacts required for forensic imaging and memory analysis.

Adım Adım Çözüm

1
Identify the active threat and assess the evidence state.
The workstation is undergoing an active remote attack, and volatile RAM holds vital forensic evidence.
Understanding the order of volatility dictates that live RAM data will be lost if the machine is powered off.
2
Isolate the compromised system from all network connections.
Network communication is terminated, stopping the remote attacker's access and preventing lateral spread across the network.
Network isolation contains the security incident immediately without altering or erasing volatile RAM evidence.
3
Escalate the incident to the designated Incident Response / Security Operations team.
Proper authorities take ownership of evidence collection and chain of custody documentation.
First responders must follow official reporting escalation policies once containment is established.

A system builder is selecting a power supply unit (PSU) for a custom workstation. The planned hardware components have the following continuous power demands:

- Central Processing Unit (CPU): 105 W105\text{ W}
- Dedicated Graphics Card (GPU): 250 W250\text{ W}
- Solid-State Drives and Cooling Fans: 45 W45\text{ W}
- Sound Capture Expansion Card: 20 W20\text{ W}

To prevent power throttling and allow for system longevity, the technician specifies that the total power consumption under full load must not exceed 80%80\% of the power supply's total rated wattage rating (providing a 20%20\% safety capacity margin). Which of the following is the minimum PSU wattage rating required for this system?

Cevabı ve açıklamayı göster

Cevap: 525 W525\text{ W}

Cevap

The minimum recommended power supply unit rating is 525 W525\text{ W}.
The total continuous power draw of all components is 105 W+250 W+45 W+20 W=420 W105\text{ W} + 250\text{ W} + 45\text{ W} + 20\text{ W} = 420\text{ W}. To ensure this total load does not exceed 80%80\% of the power supply's continuous capacity rating, divide 420 W420\text{ W} by 0.800.80, which equals 525 W525\text{ W}.

Adım Adım Çözüm

1
Calculate total continuous component power draw
105 W+250 W+45 W+20 W=420 W105\text{ W} + 250\text{ W} + 45\text{ W} + 20\text{ W} = 420\text{ W}
Sum all individual hardware power requirements across CPU, GPU, drives/fans, and expansion cards.
2
Apply the 80% maximum target load constraint
420 W0.80=525 W\frac{420\text{ W}}{0.80} = 525\text{ W}
Dividing total power draw by 0.80 establishes the minimum rated PSU wattage needed so that 420 W represents exactly 80% of total capacity.
