      4. SATA power<\/span><\/li>\n<\/ol>\n

        Correct Answer: 3<\/b><\/p>\n

        Explanation:<\/b><\/p>\n

        The 24-pin ATX connector commonly supplies primary power from a desktop power supply to the motherboard. It provides several voltage rails and ground connections required by motherboard circuitry. EPS12V connectors generally provide additional processor power, PCIe auxiliary connectors supply dedicated power to certain expansion cards, and SATA power connectors supply compatible storage devices. Technicians should carefully distinguish these connectors because forcing an incompatible power connector into a socket can damage hardware. Proper motherboard power installation is essential for stable startup and reliable system operation.<\/span><\/p>\n

        Question 184.<\/b><\/h3>\n

        Which feature automatically adjusts CPU operating speed based on workload?<\/b><\/p>\n

          \n
        1. Screen scaling<\/span><\/li>\n
        2. Dynamic frequency scaling<\/span><\/li>\n
        3. Packet filtering<\/span><\/li>\n
        4. Disk mirroring<\/span><\/li>\n<\/ol>\n

          Correct Answer: 2<\/b><\/p>\n

          Explanation:<\/b><\/p>\n

          Dynamic frequency scaling allows a processor to adjust its operating frequency according to workload, power requirements, and thermal conditions. When demand is low, the processor may reduce its frequency and power consumption. Under heavier workloads, it can increase performance when thermal and power limits permit. Screen scaling changes display presentation, packet filtering controls network traffic, and disk mirroring duplicates storage data. Dynamic frequency management is especially useful in mobile systems because it can balance performance with battery life. Technicians should understand that processor frequency can therefore change during normal operation.<\/span><\/p>\n

          Question 185.<\/b><\/h3>\n

          Which device extends an Ethernet connection beyond a cable’s normal reach?<\/b><\/p>\n

          3. Transceiver<\/span><\/li>\n
          4. Firewall<\/span><\/li>\n<\/ol>\n

            Correct Answer: 1<\/b><\/p>\n

            Explanation:<\/b><\/p>\n

            A repeater regenerates network signals so communication can continue across greater distances than a single cable segment might support. It receives a signal, restores it, and retransmits it toward the next segment. A patch panel organizes and terminates network cabling, a transceiver converts between signaling formats or media depending on the implementation, and a firewall filters network traffic according to security rules. Technicians should understand the difference between signal-extension equipment and switching or routing devices when designing or troubleshooting network infrastructure.<\/span><\/p>\n

            Question 186.<\/b><\/h3>\n

            2. ECC<\/span><\/li>\n
            3. XMP<\/span><\/li>\n
            4. Registered buffering<\/span><\/li>\n<\/ol>\n

              Correct Answer: 2<\/b><\/p>\n

              Explanation:<\/b><\/p>\n

              Error-Correcting Code, or ECC, memory can detect and correct certain memory errors, particularly single-bit errors. It is commonly used in servers, workstations, and other environments where memory reliability is especially important. Dual-channel operation increases memory bandwidth, XMP provides memory-performance configuration profiles on supported systems, and registered memory uses buffering to reduce electrical loading. ECC support requires compatibility among the processor, motherboard, and memory modules. Technicians should verify platform requirements before installing ECC memory because not every consumer system supports it.<\/span><\/p>\n

              Question 187.<\/b><\/h3>\n

              Which port is commonly associated with remote desktop services?<\/b><\/p>\n

              1. 21<\/span><\/li>\n
              2. 25<\/span><\/li>\n
              3. 3389<\/span><\/li>\n
              4. 53<\/span><\/li>\n<\/ol>\n

                Correct Answer: 3<\/b><\/p>\n

                Explanation:<\/b><\/p>\n

                TCP port 3389 is commonly associated with Microsoft Remote Desktop Protocol, or RDP. RDP allows users to interact with a remote Windows system through a graphical session. Port 21 is traditionally associated with FTP control traffic, port 25 is associated with SMTP, and port 53 is used by DNS. Technicians troubleshooting remote desktop connectivity should consider firewall rules, network reachability, service status, authentication, and security policies. Exposing remote desktop services directly to untrusted networks can create security risks, so appropriate protections should be implemented.<\/span><\/p>\n

                3. Network tap<\/span><\/li>\n
                4. Keystone jack<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 1<\/b><\/p>\n

                  Explanation:<\/b><\/p>\n

                  A media converter changes network signaling from one physical medium to another, such as converting fiber-optic signals to copper Ethernet. This allows different cable technologies to communicate while maintaining network connectivity. A patch panel provides organized cable termination, a network tap provides traffic-monitoring access, and a keystone jack provides a modular physical connection point. Media converters are useful when existing infrastructure uses different cable types or when fiber must connect to copper-based network equipment. Technicians should verify supported speeds, connector types, and transmission standards when selecting a converter.<\/span><\/p>\n

                    Correct Answer: 2<\/b><\/p>\n

                    Explanation:<\/b><\/p>\n

                    Tethering allows a mobile device to share its cellular Internet connection with another device. Depending on the device and configuration, tethering can operate through Wi-Fi, USB, or Bluetooth. Roaming refers to using a cellular network outside the primary service area, pairing establishes a relationship between compatible Bluetooth devices, and casting sends compatible content to another display or receiver. Technicians should consider carrier restrictions, authentication, battery usage, and connection method when configuring tethering. Wi-Fi hotspot functionality is a common form of wireless tethering.<\/span><\/p>\n

                    Question 190.<\/b><\/h3>\n

                    Which storage interface is designed for modern PCIe-based solid-state drives?<\/b><\/p>\n

                    1. PATA<\/span><\/li>\n
                    2. SCSI<\/span><\/li>\n
                    3. IDE<\/span><\/li>\n
                    4. NVMe<\/span><\/li>\n<\/ol>\n

                      Correct Answer: 4<\/b><\/p>\n

                      Explanation:<\/b><\/p>\n

                      NVMe, or Non-Volatile Memory Express, is designed specifically for high-speed nonvolatile storage and commonly operates over PCI Express. It provides a storage protocol optimized for solid-state drives and can offer substantially lower latency and higher parallelism than older storage protocols. PATA and IDE are legacy storage technologies, while SCSI represents an older family of storage interfaces and protocols. Technicians should understand that NVMe commonly appears in M.2 form factors, although M.2 itself describes a physical form factor rather than automatically identifying the storage protocol.<\/span><\/p>\n

                      Question 191.<\/b><\/h3>\n

                      Which technology provides electrical protection against brief voltage spikes?<\/b><\/p>\n

                                      An accelerometer detects changes in movement and orientation and can provide information used by a laptop or mobile device to rotate its display automatically. The operating system can interpret sensor data to determine whether the device is being held in portrait or landscape orientation. A TPM provides security functions, an optical sensor detects light or images depending on its design, and a touchpad controller processes touchpad input. Automatic orientation features depend on both hardware sensor support and operating-system software capable of interpreting the sensor information.<\/span><\/p>\n

                                        Correct Answer: 2<\/b><\/p>\n

                                        Explanation:<\/b><\/p>\n

                                        The SATA power connector supplies electrical power to compatible SATA storage devices such as hard drives and SATA solid-state drives. It is wider than the SATA data connector and provides the required power rails for the drive. Berg connectors were historically associated with floppy drives, while EPS12V and ATX12V connectors are used primarily for motherboard and processor power. Technicians should distinguish SATA power from SATA data because both are required for a typical internal SATA drive installation. Incorrect power connections can prevent drives from operating properly.<\/span><\/p>\n

                                          Correct Answer: 1<\/b><\/p>\n

                                          Explanation:<\/b><\/p>\n

                                          A KVM, or Keyboard Video Mouse, switch allows a user to control multiple computers using shared keyboard, video, and mouse peripherals. The user can switch between connected systems without requiring separate input devices and displays for each computer. A power strip distributes electrical power, a USB hub expands available USB ports, and a network bridge connects network segments. KVM switches are commonly used in server rooms, testing environments, and workstations where multiple systems must be managed from one console. Technicians should verify supported video standards and peripheral connections when selecting a KVM device.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
