    Which memory form factor is commonly found in laptops and other compact computers?<\/b><\/p>\n

      \n
    1. SO-DIMM<\/span><\/li>\n
    2. DIMM<\/span><\/li>\n
    3. PCIe<\/span><\/li>\n
    4. M.2<\/span><\/li>\n<\/ol>\n

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

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

      SO-DIMM, or Small Outline Dual Inline Memory Module, is a compact memory-module form factor commonly used in laptops, small-form-factor computers, and other space-constrained devices. Its smaller physical dimensions make it suitable for systems where standard desktop DIMMs would not fit. DIMMs are more commonly used in desktop computers, while PCIe is an expansion interface and M.2 is a compact connector and form factor commonly used for storage devices. Therefore, SO-DIMM is the appropriate memory form factor for a typical laptop.<\/span><\/p>\n

      Question 203<\/b><\/h3>\n

      Which component is used to provide wireless network connectivity to a desktop computer?<\/b><\/p>\n

        \n
      1. Sound card<\/span><\/li>\n
      2. Wireless NIC<\/span><\/li>\n
      3. RAID controller<\/span><\/li>\n
      4. Capture card<\/span><\/li>\n<\/ol>\n

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

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

        A wireless network interface controller, or wireless NIC, allows a computer to communicate with wireless networks using supported Wi-Fi standards. It may be integrated into the motherboard or installed as an expansion card or USB adapter. A wireless NIC communicates with a wireless access point or router rather than requiring a physical Ethernet cable. A sound card handles audio, a RAID controller manages storage arrays, and a capture card receives media input. Therefore, a wireless NIC provides the required wireless network connectivity.<\/span><\/p>\n

        Question 204<\/b><\/h3>\n

        Which type of cable uses light signals instead of electrical signals to transmit data?<\/b><\/p>\n

          \n
        1. Coaxial<\/span><\/li>\n
        2. Twisted-pair<\/span><\/li>\n
        3. Fiber-optic<\/span><\/li>\n
        4. Serial<\/span><\/li>\n<\/ol>\n

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

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

          Fiber-optic cable transmits data using pulses of light through optical fibers. Because it does not rely on electrical signals, fiber is highly resistant to electromagnetic interference and can support high bandwidth over long distances. Coaxial and twisted-pair cables transmit electrical signals, while traditional serial cables also use electrical signaling. Fiber-optic installations commonly use connectors such as LC, SC, or ST depending on the equipment and environment. Therefore, fiber-optic cable is the transmission medium described in the question.<\/span><\/p>\n

          Question 205<\/b><\/h3>\n

          Which connector is commonly used for a wired telephone connection rather than standard Ethernet networking?<\/b><\/p>\n

          1. RJ11<\/span><\/li>\n
          2. RJ45<\/span><\/li>\n
          3. HDMI<\/span><\/li>\n
          4. DisplayPort<\/span><\/li>\n<\/ol>\n

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

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

            RJ11 is commonly associated with traditional telephone connections and is smaller than the RJ45-style connector commonly used for Ethernet networking. RJ11 connections may be used for telephone handsets, DSL equipment, and related services depending on the installation. RJ45 is commonly used for Ethernet, while HDMI and DisplayPort are digital audio\/video interfaces. Although connector appearances can sometimes be confused, technicians should identify the correct cable and port based on the equipment specifications. Therefore, RJ11 is the appropriate connector for traditional telephone wiring.<\/span><\/p>\n

            Question 206<\/b><\/h3>\n

            Which technology allows a smartphone to make contactless payments when brought close to a compatible payment terminal?<\/b><\/p>\n

            1. GPS<\/span><\/li>\n
            2. NFC<\/span><\/li>\n
            3. Bluetooth<\/span><\/li>\n
            4. Wi-Fi<\/span><\/li>\n<\/ol>\n

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

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

              Near Field Communication, or NFC, enables very short-range wireless communication between compatible devices. Smartphones can use NFC for contactless payments by communicating with a compatible payment terminal when the devices are brought close together. NFC can also support access credentials, device pairing, and other proximity-based applications. GPS is used for positioning, Bluetooth is commonly used for peripheral communication, and Wi-Fi provides wireless network connectivity. Therefore, NFC is the technology that enables the described contactless payment functionality.<\/span><\/p>\n

              Question 207<\/b><\/h3>\n

              Which type of cooling system uses a fan and heat sink to remove heat from a processor?<\/b><\/p>\n

                \n
              1. Liquid cooling<\/span><\/li>\n
              2. Passive cooling<\/span><\/li>\n
              3. Air cooling<\/span><\/li>\n
              4. Phase-change cooling<\/span><\/li>\n<\/ol>\n

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

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

                Air cooling uses a heat sink to absorb and spread heat from a processor, while a fan moves air across the heat sink to carry that heat away. It is one of the most common CPU cooling methods because it is relatively simple and inexpensive. Liquid cooling instead circulates coolant through a closed or custom loop, while passive cooling relies primarily on heat sinks without an active fan. Phase-change cooling uses specialized refrigeration principles. Therefore, a fan and heat sink combination represents an air-cooling solution.<\/span><\/p>\n

                Question 208<\/b><\/h3>\n

                A computer’s CPU temperature rises rapidly under normal workloads and the system begins reducing performance to control heat. What is this behavior called?<\/b><\/p>\n

                  \n
                1. Overclocking<\/span><\/li>\n
                2. Throttling<\/span><\/li>\n
                3. Mirroring<\/span><\/li>\n
                4. Spooling<\/span><\/li>\n<\/ol>\n

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

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

                  Thermal throttling occurs when a processor automatically reduces its operating frequency or performance to lower heat generation and prevent thermal damage. It can occur when cooling is inadequate, thermal paste has degraded, vents are blocked, or the cooling fan is malfunctioning. Throttling protects the processor but can result in noticeable performance reductions. Overclocking increases operating performance beyond standard settings, mirroring duplicates storage data, and spooling temporarily queues data for processing or output. Therefore, reduced CPU performance caused by excessive temperature is thermal throttling.<\/span><\/p>\n

                  Question 209<\/b><\/h3>\n

                  Which storage technology is generally more resistant to physical shock because it has no spinning platters or moving read\/write heads?<\/b><\/p>\n

                    \n
                  1. HDD<\/span><\/li>\n
                  2. Tape<\/span><\/li>\n
                  3. SSD<\/span><\/li>\n
                  4. Optical disc<\/span><\/li>\n<\/ol>\n

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

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

                    Solid-state drives use flash memory rather than spinning magnetic platters and mechanical read\/write heads. The absence of moving mechanical components generally makes SSDs more resistant to physical shock and vibration than traditional HDDs. This characteristic is particularly useful in laptops and portable systems that may experience movement during operation. HDDs and tape drives use mechanical or magnetic mechanisms, while optical discs rely on physical media read by a laser. Therefore, an SSD provides the solid-state storage design described in the question.<\/span><\/p>\n

                    Question 210<\/b><\/h3>\n

                    Which connector is commonly used for older keyboards and mice and is usually identified by separate ports for each device?<\/b><\/p>\n

                      \n
                    1. PS\/2<\/span><\/li>\n
                    2. USB-C<\/span><\/li>\n
                    3. HDMI<\/span><\/li>\n
                    4. RJ45<\/span><\/li>\n<\/ol>\n

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

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

                      PS\/2 is a legacy interface commonly used for keyboards and mice on older desktop computers. Traditional systems often included separate PS\/2 ports, typically using different colors to distinguish keyboard and mouse connections. USB has largely replaced PS\/2 for modern peripheral connectivity, while USB-C provides a newer reversible connector. HDMI is primarily used for digital audio and video, and RJ45 is commonly associated with Ethernet networking. Therefore, PS\/2 is the legacy peripheral interface described.<\/span><\/p>\n

                      Question 211<\/b><\/h3>\n

                      Which Windows command can display the hostname and IP address information associated with a DNS lookup?<\/b><\/p>\n

                        \n
                      1. format<\/span><\/li>\n
                      2. sfc<\/span><\/li>\n
                      3. nslookup<\/span><\/li>\n
                      4. chkdsk<\/span><\/li>\n<\/ol>\n

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

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

                        The nslookup utility is designed to query DNS servers and can display information about domain-name resolution. Technicians can use it to determine whether a hostname resolves to an expected IP address and to investigate DNS-related connectivity problems. The command can also be useful for querying specific DNS records and servers. Format prepares storage volumes, sfc checks protected Windows system files, and chkdsk examines file-system and disk-related conditions. Therefore, nslookup is the appropriate utility for investigating DNS resolution.<\/span><\/p>\n

                        Question 212<\/b><\/h3>\n

                        Which Windows command is commonly used to release the current DHCP address and request a new one?<\/b><\/p>\n

                          \n
                        1. tracert<\/span><\/li>\n
                        2. ipconfig<\/span><\/li>\n
                        3. ping<\/span><\/li>\n
                        4. hostname<\/span><\/li>\n<\/ol>\n

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

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

                          The ipconfig command provides several options for managing and viewing Windows network configuration. The <\/span>\/release<\/span> option can release the current DHCP-assigned IPv4 configuration, while <\/span>\/renew<\/span> requests a new DHCP configuration from an available DHCP server. This can be useful when troubleshooting incorrect IP addressing or DHCP-related connectivity problems. Tracert examines network paths, ping tests connectivity, and hostname displays the computer’s name. Therefore, ipconfig is the appropriate command for releasing and renewing DHCP configuration.<\/span><\/p>\n

                          Question 213<\/b><\/h3>\n

                          Which type of network address is normally assigned to a device by a DHCP server for communication on an IPv4 network?<\/b><\/p>\n

                            \n
                          1. IP address<\/span><\/li>\n
                          2. MAC address<\/span><\/li>\n
                          3. URL<\/span><\/li>\n
                          4. Hostname<\/span><\/li>\n<\/ol>\n

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

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

                            A DHCP server can automatically assign an IPv4 address to a network client along with related configuration such as the subnet mask, default gateway, and DNS server information. The IP address provides logical network addressing that allows devices to communicate across IP networks. A MAC address is a hardware-layer identifier associated with a network interface, while a URL identifies a resource location and a hostname identifies a system or service by name. Therefore, the IP address is the network address commonly assigned through DHCP.<\/span><\/p>\n

                            Question 214<\/b><\/h3>\n

                            Which network service automatically translates a domain name such as a website address into an IP address?<\/b><\/p>\n

                              \n
                            1. DHCP<\/span><\/li>\n
                            2. DNS<\/span><\/li>\n
                            3. NTP<\/span><\/li>\n
                            4. SNMP<\/span><\/li>\n<\/ol>\n

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

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

                              DNS, or Domain Name System, translates domain names into IP addresses so network clients can locate the appropriate systems and services. When a user enters a website name, the device typically performs DNS resolution to determine the corresponding address before establishing communication. DHCP provides network configuration, NTP synchronizes clocks, and SNMP supports network monitoring and management. DNS can also provide information through different record types, including records used for mail and service discovery. Therefore, DNS performs the required name-resolution function.<\/span><\/p>\n

                              Question 215<\/b><\/h3>\n

                              Which security method encrypts the contents of a storage drive so that data cannot normally be read without the required authentication or recovery key?<\/b><\/p>\n

                                \n
                              1. File compression<\/span><\/li>\n
                              2. Disk defragmentation<\/span><\/li>\n
                              3. Full-disk encryption<\/span><\/li>\n
                              4. Screen locking<\/span><\/li>\n<\/ol>\n

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

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

                                Full-disk encryption protects stored data by encrypting the contents of a storage device. Without the appropriate authentication credentials, encryption key, or recovery mechanism, an unauthorized person who removes the drive generally cannot simply read its contents as ordinary files. Screen locking protects an active operating-system session but does not by itself protect data if the storage device is removed. File compression reduces storage requirements, while defragmentation reorganizes certain types of stored data. Therefore, full-disk encryption provides the described protection for data at rest.<\/span><\/p>\n

                                Question 216<\/b><\/h3>\n

                                Which authentication factor is classified as something a user knows?<\/b><\/p>\n

                                  \n
                                1. Fingerprint<\/span><\/li>\n
                                2. Smart card<\/span><\/li>\n
                                3. Password<\/span><\/li>\n
                                4. Security key<\/span><\/li>\n<\/ol>\n

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

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

                                  A password is a knowledge factor because the user must know the secret information to authenticate successfully. Other examples of knowledge factors include PINs and passphrases. A fingerprint is a biometric factor based on something the user is, while a smart card and security key are generally possession factors because the user physically has them. Combining different factor categories provides multifactor authentication and can improve account security. Therefore, a password is the authentication factor that belongs to the knowledge category.<\/span><\/p>\n

                                  Question 217<\/b><\/h3>\n

                                  Which type of malware disguises itself as legitimate software to trick a user into installing or executing it?<\/b><\/p>\n

                                    \n
                                  1. Trojan<\/span><\/li>\n

                                  4. Rootkit<\/span><\/li>\n<\/ol>\n

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

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

                                    A Trojan is malware that disguises itself as legitimate or useful software in an attempt to persuade users to install or execute it. Once executed, the malicious program may perform unauthorized activities such as stealing information, installing additional malware, or providing remote access. Worms are characterized by self-replication and network propagation, ransomware commonly attempts to deny access to data, and rootkits focus on maintaining concealed privileged access. Therefore, a Trojan specifically matches the described deceptive software technique.<\/span><\/p>\n

                                    Question 218<\/b><\/h3>\n

                                    Which physical security technique involves following an authorized person through a secured door without independently authenticating?<\/b><\/p>\n

                                      \n
                                    1. Phishing<\/span><\/li>\n

                                    4. Shoulder surfing<\/span><\/li>\n<\/ol>\n

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

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

                                      Tailgating is a physical security violation in which an unauthorized person follows an authorized individual through a controlled entrance without presenting their own valid credentials. Attackers may exploit courtesy, distraction, or a lack of security awareness to gain access to restricted areas. Phishing is a social-engineering attack involving deceptive communications, spoofing involves impersonation or falsification, and shoulder surfing involves observing sensitive information being entered or displayed. Organizations can reduce tailgating through security awareness, access controls, security personnel, and appropriately designed entry systems.<\/span><\/p>\n

                                      Question 219<\/b><\/h3>\n

                                      Which backup strategy generally requires the original full backup plus all subsequent incremental backups to perform a complete restoration?<\/b><\/p>\n

                                      1. Full backup only<\/span><\/li>\n
                                      2. Differential backup<\/span><\/li>\n
                                      3. Incremental backup chain<\/span><\/li>\n
                                      4. Disk mirroring<\/span><\/li>\n<\/ol>\n

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

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

                                        An incremental backup strategy stores changes since the previous backup, creating a sequence of backup sets. To perform a complete restoration, the technician generally needs the most recent full backup followed by each required incremental backup in chronological order. This can make incremental backups efficient in terms of storage and backup time, but restoration can be more involved. A differential strategy typically requires the original full backup and the latest differential backup. Disk mirroring provides redundancy rather than a conventional historical backup chain. Therefore, the incremental chain matches the scenario.<\/span><\/p>\n

                                        Question 220<\/b><\/h3>\n

                                        A technician installs a new expansion card, but the operating system does not recognize it. What should be checked first?<\/b><\/p>\n

                                          \n
                                        1. Whether the card is properly seated and receives required power<\/span><\/li>\n
                                        2. Whether the monitor wallpaper is correct<\/span><\/li>\n
                                        3. Whether the printer has enough paper<\/span><\/li>\n
                                        4. Whether the keyboard language is configured<\/span><\/li>\n<\/ol>\n

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

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

                                          When newly installed hardware is not recognized, the technician should first verify the physical installation. The expansion card should be firmly seated in the correct compatible slot, required auxiliary power connectors should be attached, and the system should be checked for obvious installation issues. After physical checks, the technician can investigate firmware settings, operating-system detection, drivers, and hardware compatibility. Monitor wallpaper, printer paper, and keyboard language are unrelated to hardware recognition. Therefore, verifying seating and required power is an appropriate first troubleshooting step.<\/span><\/p>\n
