CompTIA 220-1101 CompTIA A+ Certification Exam Core 1 Exam Practice Test

Answer : C

GPS (Global Positioning System) is a feature that allows a phone to determine its location by receiving signals from satellites. A maps application relies on GPS to provide accurate directions and navigation. If GPS is turned off or not working properly, the maps application may not function as expected.

The other options are not relevant to the issue. Airplane mode is a setting that disables all wireless communication on a phone, including cellular, Wi-Fi, Bluetooth, and GPS. However, since the representative runs a speed test and gets ~10Mbps in both directions, it means that airplane mode is not enabled. PRL (Preferred Roaming List) is a database that contains information about the cellular towers and networks that a phone can connect to. Updating the PRL can improve the phone's signal strength and coverage, but it does not affect the maps application. LTE (Long Term Evolution) is a standard for high-speed wireless communication on mobile devices. It is related to the cellular data speed and quality, but not to the maps application.

To troubleshoot the issue, the technician should check the GPS settings on the phone and make sure that it is turned on and has a clear view of the sky. The technician should also verify that the maps application has permission to access the GPS location. If the problem persists, the technician may suggest resetting the network settings, updating the phone's software, or contacting the maps application's support team.

Answer : A

The pink hue is most likely caused by physical cabling issues

the output on a monitor is clear but has a pink hue, it could be due to an issue with the physical cabling connecting the monitor to the computer. The video signal may be degraded or distorted due to a damaged or loose cable. The technician should check and replace the cable if necessary to resolve the issue.

Answer : B

The digitizer is the component that enables input on a mobile device's touch screen. It is a transparent layer that sits over the screen and detects the location of touch inputs. OLED (Organic Light Emitting Diode) is a type of display technology. Inverter is a component used in older LCD displays to provide power to the backlight. CMOS (Complementary Metal-Oxide-Semiconductor) sensor is a type of image sensor used in digital cameras and smartphones to capture images. Reference: CompTIA A+ Certification Exam: Core 1 - Page 177

Answer : A

A network tap is a device that can be used to monitor and analyze the traffic and data that pass through a network. A network tap can be inserted between two network devices, such as a switch and a router, and capture the packets that flow in both directions. A network tap can then send a copy of the packets to another device, such as a laptop or a server, for inspection and troubleshooting. A network tap can help diagnose and resolve network issues, such as performance, security, or configuration problems.

A network tap is the least disruptive tool for checking the status of a local network device, because it does not interfere with the normal operation of the network. A network tap does not alter or block the packets that it captures, and it does not introduce any latency or noise to the network. A network tap can also operate in stealth mode, which means that it is invisible to the network devices and cannot be detected by hackers or attackers.

Answer : A

A DHCP (Dynamic Host Configuration Protocol) server is a server type that can dynamically assign IP addresses and other network configuration parameters to clients, such as primary and secondary DNS (Domain Name System) servers. DNS servers are responsible for resolving hostnames to IP addresses and vice versa. A global catalog server, a web server, and a name server are not involved in DHCP operations.

Answer : C

DNS stands for Domain Name System, which is a network service that translates hostnames to IP addresses. Hostnames are human-readable names that identify devices or services on the Internet, such as www.google.com or mail.yahoo.com. IP addresses are numerical identifiers that specify the location of devices or services on the Internet, such as 172.217.14.206 or 98.137.11.163. DNS allows users to access websites or services by using hostnames instead of IP addresses, which are easier to remember and type. DNS also allows hostnames to change their IP addresses without affecting the users, which can improve performance and security.

Answer : C

The BEST solution to mitigate spam that appears to come from an organization's own domain is to implement SPF (Sender Policy Framework). SPF is an email validation protocol designed to detect and prevent email spoofing, which is a common tactic used by spammers. By publishing SPF records in the organization's DNS (Domain Name System), the recipient's mail server can check if an incoming email originated from a valid source. If the email fails SPF authentication, it can be blocked or flagged as spam. Therefore, SPF helps to prevent email spoofing and mitigate the risk of spam coming from an organization's own domain
