Items

Remote Desktop Protocol (RDP)
Microsoft Remote Assistance (MSRA)
Secure Shell (SSH)
Telnet
Virtual Network Computing (VNC)

Matches

Show answer & explanation

Answer

RDP matches TCP 3389 with host support limited to Windows Pro/Enterprise; MSRA matches TCP 3389 session sharing supported on Home and Pro editions; SSH matches encrypted CLI administration on TCP 22; Telnet matches unencrypted cleartext CLI management on TCP 23; VNC matches cross-platform RFB graphical control on TCP 5900.
Matching each technology correctly requires distinguishing between Windows OS edition constraints (RDP host vs MSRA), default port numbers (TCP 22, 23, 3389, 5900), and protocol security characteristics (SSH encrypted vs Telnet cleartext; RDP/MSRA native vs VNC RFB cross-platform).

Step-by-Step Solution

1
Analyze Windows graphical remote access protocols and edition constraints.
Differentiate RDP (discrete session, host requires Windows Pro/Enterprise/Education, TCP 3389) from MSRA (shared active session, invitation-based, works on Home editions, TCP 3389).
CompTIA exams strictly evaluate the host capability limitation of Windows Home edition regarding incoming RDP versus user-assisted MSRA.
2
Evaluate command-line interface (CLI) remote access protocols and security postures.
Identify SSH as the secure, encrypted terminal access protocol on TCP port 22, and Telnet as the legacy, unencrypted cleartext terminal protocol on TCP port 23.
Security best practices demand replacing unencrypted protocols like Telnet with encrypted alternatives like SSH.
3
Identify cross-platform graphical remote control standards.
Associate VNC with the Remote Frame Buffer (RFB) protocol and default listening port TCP 5900.
VNC is the standard open-source cross-platform tool for graphical desktop access across mixed operating system environments.

Click a left item, then click its matching right item

Items

A thermal transfer label printer feeds media properly but produces completely blank labels.
A monochrome laser printer outputs pages featuring a sharp, continuous black vertical line down the entire length of every page.
A high-resolution inkjet printer produces photos with white horizontal streaks and missing color bands.
A network MFD produces copies with a vertical line when using the ADF, but flatbed scans of the same document are clear.

Matches

Show answer & explanation

Answer

Thermal transfer blank labels match backward ribbon installation; Laser printer continuous vertical black line matches photosensitive drum surface scratch; Inkjet horizontal missing streaks match clogged printhead nozzles; MFD ADF vertical line vs clear flatbed matches dirty ADF scanner glass strip.
Each print technology exhibits distinct physical breakdown characteristics: thermal transfer ribbons must have their wax/resin side against the media; damaged laser drum surfaces continuously attract toner; blocked inkjet nozzles prevent ink flow along sweep lines; and fixed ADF glass debris creates static image lines as paper moves.

Step-by-Step Solution

1
Analyze thermal transfer operation.
Identify that thermal transfer relies on ribbon ink facing the media. Backward ribbon orientation prevents ink deposition.
Direct heat cannot melt ink onto media if the coated side points outward.
2
Analyze laser printing drum mechanics.
Correlate a continuous vertical line along the direction of paper travel with a physical drum defect.
As the drum rotates, a scratch prevents charge retention at that exact horizontal axis position.
3
Analyze inkjet liquid ink delivery.
Associate missing horizontal lines/streaks with blocked ink nozzles.
When printhead nozzles clog, specific pinholes fail to eject ink droplets as the head sweeps horizontally.
4
Compare ADF vs. flatbed scanning mechanisms on an MFD.
Isolate the ADF glass strip as the source of the line artifact.
Flatbed scanning moves the reader head under full glass, whereas ADF moves paper over a fixed glass strip; debris on the fixed strip affects every moving page.

Matches

Show answer & explanation

Answer

DDR4 Desktop DIMM matches 288-pin full-size module at 1.2V with motherboard power regulation; DDR5 Desktop DIMM matches 288-pin full-size module at 1.1V with onboard PMIC and dual 32-bit subchannels; DDR4 Laptop SODIMM matches 260-pin small form factor module at 1.2V; DDR5 Laptop SODIMM matches 262-pin small form factor module at 1.1V with onboard PMIC.
Matching relies on recognizing form factor (DIMM for desktop vs SODIMM for portable systems), pin counts (288 pins for both DDR4 and DDR5 full-size DIMMs, 260 pins for DDR4 SODIMMs, and 262 pins for DDR5 SODIMMs), operating voltages (1.2V1.2\text{V} for DDR4 vs 1.1V1.1\text{V} for DDR5), and power regulation location (motherboard for DDR4 vs onboard PMIC for DDR5).

Step-by-Step Solution

1
Differentiate between full-size desktop modules (DIMMs) and laptop/compact modules (SODIMMs).
Desktop DIMMs utilize 288 pins for both DDR4 and DDR5 generations, whereas SODIMMs use 260 pins for DDR4 and 262 pins for DDR5.
Form factor directly dictates physical size and pin density suitable for motherboard expansion slots.
2
Analyze standard operating voltages and power delivery architectures for DDR4 versus DDR5.
DDR4 operates at 1.2V1.2\text{V} with power delivery controlled by the motherboard VRM. DDR5 operates at 1.1V1.1\text{V} and features onboard power management via a Power Management Integrated Circuit (PMIC).
DDR5 moves voltage regulation from the system board directly onto the RAM module for improved power efficiency and signal stability.
3
Map each memory generation and form factor combination to its corresponding specification pair.
DDR4 DIMM \rightarrow 288-pin, 1.2V1.2\text{V}, motherboard VRM; DDR5 DIMM \rightarrow 288-pin, 1.1V1.1\text{V}, onboard PMIC & dual subchannels; DDR4 SODIMM \rightarrow 260-pin, 1.2V1.2\text{V}; DDR5 SODIMM \rightarrow 262-pin, 1.1V1.1\text{V}, onboard PMIC.

Question 25Question

A systems administrator is configuring virtual network interface cards (vNICs) for several enterprise virtual machines (VMs) running on a hypervisor. Match each virtual network adapter mode on the left with the operational scenario on the right that matches its exact connectivity and security boundaries.

Click a left item, then click its matching right item

Items

Bridged Mode
Network Address Translation (NAT) Mode
Host-Only Mode
Internal / Private Mode

Matches

Show answer & explanation

Answer

Bridged mode corresponds to assigning a dedicated physical subnet IP address for direct client queries; NAT mode corresponds to outbound internet connectivity via shared host IP translation; Host-Only mode corresponds to network traffic restricted to the host system and local VMs; Internal/Private mode corresponds to isolated VM-to-VM traffic excluding the host OS and physical network.
Each virtual adapter mode defines explicit boundaries for network routing and security isolation. Bridged mode places the guest directly onto the physical segment. NAT mode translates traffic outbound using the host's IP address. Host-Only mode creates a isolated network consisting of the host OS and guest VMs. Internal/Private mode constructs a private virtual switch that omits the host OS completely for total network isolation.

Step-by-Step Solution

1
Analyze physical network boundary requirement for direct incoming server traffic.
Bridged mode connects the VM directly to the physical network infrastructure, treating the guest VM as an independent physical network host with its own lease/static IP.
Servers requiring direct visibility on the local physical network need Bridged mode.
2
Evaluate outbound internet access needs combined with private IP translation.
NAT mode leverages virtual translation services, permitting outbound repository updates while masking the VM behind the host's physical interface.
NAT provides external network reachability without exposing the guest VM directly to incoming external connections.
3
Differentiate between host-accessible internal networking and strictly host-isolated internal networking.
Host-Only mode allows host-to-guest and guest-to-guest communication without physical NIC access. Internal/Private mode isolates communication strictly among guests, disconnecting the host OS.
Malware sandbox testing often requires isolated guest-to-guest segments that prevent VM-to-host lateral infection.

Matches

Show answer & explanation

Answer

Disabling Remote Registry and blocking SMB port 445 prevents unauthorized remote tampering and SMB-based lateral movement. Enforcing screen saver locks mitigates unauthorized physical access on unattended endpoints. Renaming default admin accounts and disabling guest accounts mitigates automated credential spraying against standard account names. Disabling AutoRun/AutoPlay blocks automatic malicious script execution from plugged-in storage media.
Each workstation hardening measure targets a specific attack surface: restricting Remote Registry and SMB port 445 neutralizes remote management exploitation; enforcing idle screen locks secures physical access in shared office environments; disabling default accounts neutralizes automated brute-force attacks against predictable local usernames; disabling AutoRun prevents untrusted execution of external scripts from connected peripherals.

Step-by-Step Solution

1
Analyze network hardening controls
Disabling Remote Registry and closing TCP port 445 blocks network-based registry access and SMB exploitation.
Port 445 and Remote Registry are primary vectors for remote network probing and lateral movement.
2
Evaluate physical security enforcement controls
Enforcing a timed screen lock protects idle active sessions from walk-up unauthorized users.
Unattended unlocked workstations expose sensitive data to local physical threats.
3
Assess default user account security practices
Altering default account names thwarts automated dictionary attacks targeting standard account SIDs.
Default accounts like Administrator and Guest are known targets for automated brute-forcing.
4
Examine removable storage policy restrictions
Disabling AutoRun/AutoPlay stops drive-by code execution upon insertion of USB devices.
AutoRun automatically processes setup scripts on newly attached media unless explicitly restricted by policy.

Show answer & explanation

Answer

Category 6 (Cat 6) Cable matches 10 Gbps speeds up to 55 meters. Multi-Mode Fiber (MMF) matches wider core diameter with LED/VCSEL light sources for short-to-medium distances. Single-Mode Fiber (SMF) matches narrow core diameter with laser diodes for long distances up to tens of kilometers. RG-6 Coaxial Cable matches 18 AWG center conductor with F-type connectors for cable TV and broadband.
Each cabling type is matched to its core physical and technical specification defined under standard networking guidelines: Cat 6 delivers 10 Gbps up to 55m; MMF uses a wide core with LED/VCSEL light for building backbones; SMF uses a narrow 9-micron core with laser diodes for long-distance link spans; RG-6 utilizes an 18 AWG wire terminated with F-type connectors for broadband signal delivery.

Step-by-Step Solution

1
Analyze copper twisted-pair specifications
Category 6 cable supports standard 1 Gbps up to 100 meters, but can achieve 10 Gbps up to a limited distance of 55 meters.
CompTIA A+ objectives specifically test distance limits for 10GBASE-T over Cat 6 vs Cat 6a.
2
Differentiate Multi-Mode Fiber (MMF) from Single-Mode Fiber (SMF)
MMF has a wider core for multiple light paths (LED/VCSEL light source, shorter distance), while SMF has a narrow core for a single light path (laser source, multi-kilometer distance).
Modal dispersion limits MMF to shorter runs, whereas SMF eliminates modal dispersion for long-haul carrier networks.
3
Identify coaxial cable construction and applications
RG-6 uses an 18 AWG wire and F-type connectors for broadband cable internet and satellite drops.
RG-6 replaced thinner RG-59 due to superior shielding and lower signal loss at higher frequencies.

Items

PCIe lane bifurcation configuration
USB 3.2 Gen 2x2 Key-M/Type-E internal header
8-pin EPS12V motherboard power connector
Clear CMOS (CLR_CMOS) 3-pin header configuration

Matches

Show answer & explanation

Answer

1. PCIe lane bifurcation matches splitting native CPU lanes without a multiplexer chip.
2. USB 3.2 Gen 2x2 Type-E header matches the 20-pin keyed design delivering dual-channel 10 Gbps signals.
3. 8-pin EPS12V connector matches dedicated +12V power delivery to CPU VRMs with distinct pin keying.
4. Clear CMOS 3-pin header matches moving a jumper to short RTC RAM and reset UEFI/BIOS settings.
Each motherboard term correctly pairs with its exact architectural specification: PCIe lane bifurcation divides CPU lanes without multiplexers; the USB 3.2 Gen 2x2 header uses a 20-pin Type-E standard for 20 Gbps data paths; the 8-pin EPS12V supplies CPU VRM power with specific pin keying; and the CLR_CMOS header clears stored settings when pins are bridged by a jumper.

Step-by-Step Solution

1
Analyze PCIe lane bifurcation functionality.
Bifurcation allows the motherboard firmware to divide CPU PCIe lanes across multiple devices in an expansion slot without hardware switches.
Identify the option describing lane splitting without a hardware switch.
2
Identify the internal USB 3.2 Gen 2x2 front panel connector standard.
USB 3.2 Gen 2x2 utilizes the internal 20-pin Type-E connector for 20 Gbps total throughput.
Match the 20-pin Type-E header description.
3
Distinguish between EPS12V power and PCIe auxiliary power connectors.
The 8-pin EPS12V specifically powers the CPU VRM and has distinct pin shape keying from 8-pin PCIe auxiliary power.
Match the EPS12V feature to dedicated CPU VRM +12V power.
4
Evaluate the mechanism of the CLR_CMOS header.
A 3-pin CLR_CMOS header resets motherboard BIOS settings when a jumper bridge short-circuits the configuration pins to cut volatile memory power.
Match the CLR_CMOS header to repositioning a jumper to reset RTC RAM.

Items

Configuring OS network security groups, applying OS security patches, and managing installed web server middleware on cloud virtual instances
Deploying application source code into a managed runtime framework while relying on the vendor to maintain the underlying OS, web server binaries, and database engine
Managing end-user accounts, multi-factor authentication rules, and data access policies for an enterprise cloud productivity suite
Replacing physical RAID controllers, maintaining host hypervisor updates, and managing physical facility security

Matches

Show answer & explanation

Answer

The operational tasks match their respective cloud service model responsibilities as follows: Managing guest OS patches and middleware corresponds to customer responsibilities under Infrastructure as a Service (IaaS); deploying code to a managed runtime framework corresponds to customer responsibilities under Platform as a Service (PaaS); managing user access policies for hosted applications corresponds to customer responsibilities under Software as a Service (SaaS); and maintaining host hypervisors and physical hardware is the cloud provider's core responsibility across all service models.
Each cloud service model defines a distinct boundary of operational ownership between the customer and provider under the shared responsibility model. In Infrastructure as a Service, customers control the operating system, middleware, and applications. In Platform as a Service, customers control application code and data while the vendor manages the operating system and underlying runtime framework. In Software as a Service, the vendor manages the complete software stack, leaving data governance and account access configuration to the customer. Physical infrastructure hardware and hypervisor health remain provider responsibilities across all cloud service models.

Step-by-Step Solution

1
Analyze the operational scope for guest operating system patching and virtual firewall configurations.
Identified as customer responsibilities under Infrastructure as a Service (IaaS), where the customer maintains virtual machines from the operating system upward.
IaaS provides raw compute primitives, requiring the cloud tenant to maintain the OS and middleware.
2
Evaluate the management boundary where developers only supply code while the vendor manages the OS, database engine, and runtime environment.
Identified as customer responsibilities under Platform as a Service (PaaS).
PaaS abstracts operating systems and infrastructure software to streamline application development and deployment.
3
Determine the service tier where application functionality is completely hosted and the customer manages only access credentials and stored data.
Identified as customer responsibilities under Software as a Service (SaaS).
SaaS abstracts all infrastructure and application software stacks, leaving identity governance and data management to the consumer.
4
Examine physical server hardware maintenance, facilities management, and physical hypervisor maintenance.
Identified as the Cloud Provider's responsibility across all cloud service models.
Physical infrastructure security and host hypervisor maintenance are foundational duties handled exclusively by cloud providers.
