                      CompTIA A+ Certification Exam: Core 1 Sample Questions (Q135-Q140):

                      NEW QUESTION # 135
                      Which of the following technologies can cause an application to open even though no device has been paired with the phone?

                      Answer: B

                      Explanation:
                      Near-field communication can trigger a compatible application without requiring the phone to be paired with another device. NFC operates across a very short distance, normally only a few centimetres. When a phone is brought close to an NFC tag, payment terminal, access reader, or other NFC-enabled object, the tag can provide information that causes the operating system to open a browser, payment application, configuration screen, or another registered application. Unlike Bluetooth, NFC does not require a conventional discovery and pairing process before exchanging the small amount of information needed to initiate the action. Wi-Fi connects the phone to a wireless local area network but does not inherently trigger an application through proximity. A hotspot allows the phone to share its cellular connection with other devices. Bluetooth generally requires pairing or an established device relationship for persistent peripheral communication.


                      NEW QUESTION # 136
                      A user's computer can connect to internal network resources but cannot access websites on the internet. Other users on the same network do not have this issue. Which of the following should a technician do first to troubleshoot the issue?

                      Answer: A

                      Explanation:
                      If a computer can access internal network resources but cannot reach external websites, the most likely issue is a DNS configuration problem. According to CompTIA Core 1 (220-1201) networking troubleshooting methodology, DNS should be one of the first items checked when internet access fails but local connectivity remains intact.
                      DNS translates human-readable domain names into IP addresses. If DNS settings are incorrect, missing, or pointing to an invalid server, the computer will be unable to resolve website names even though it has network connectivity. Since other users on the same network can access the internet, the issue is isolated to the individual workstation.
                      Replacing the network cable is unnecessary because internal connectivity is already working. Restarting the DHCP server would impact all users, not just one. Adjusting firewall rules on the router would affect the entire network rather than a single computer.
                      CompTIA emphasizes starting with least disruptive and most likely causes when troubleshooting. Verifying DNS settings aligns with this best-practice approach.

                      NEW QUESTION # 137
                      Which of the following devices is used to implement ACL polices for an environment?

                      Answer: A

                      Explanation:
                      A firewall implements ACLs (Access Control Lists) to filter traffic and enforce policies based on rules such as IP address, port, or protocol.
                      Why Not A (Managed switch): A managed switch supports VLANs and QoS but does not enforce ACLs at the network perimeter.
                      Why Not B (Gateway): Gateways connect networks and translate protocols but don't typically implement ACLs.
                      Why Not C (Repeater): Repeaters extend signal range but don't enforce policies.
                      CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.2, firewall concepts.


                      NEW QUESTION # 138
                      Which of the following is used to expose the wires in an unshielded twisted pair?

                      Answer: D

                      Explanation:
                      A cable stripper is used to remove the outer insulation of an unshielded twisted pair cable, exposing the internal wires for termination or inspection.


                      NEW QUESTION # 139
                      A user routinely connects and disconnects multiple devices from a laptop. Which of the following options should a technician recommend to facilitate ease of user mobility?

                      Answer: B

                      Explanation:
                      A docking station is designed to provide a central connection point for multiple peripherals, such as monitors, keyboards, mice, and network cables. It allows users to quickly connect or disconnect all devices by simply docking or undocking their laptop, improving mobility and reducing wear and tear on individual ports.
