CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 231:

  A technician is replacing a ribbon on a printer that produces faded text and Images when priming. Which of the following types of primers is the technician working on?

  A. Impact

  B. Inkjet

  C. Laser

  D. Thermal

  Correct Answer: A

  An impact printer is a type of printer that uses a ribbon to produce text and images on paper. If an impact printer is producing faded text and images when printing, it could be due to a worn-out ribbon that needs to be replaced. The technician would need to replace the ribbon on the impact printer to resolve the issue. A ribbon is a consumable component used in impact printers that uses a cloth or plastic strip coated with ink to produce text and images on paper. Examples of impact printers include dot matrix printers and line printers. References: Study Guide Section 4.6 - Printer technologies

• Question 234:

  A user reports a cell phone is getting hot. Which of the following are MOST likely to be possible causes? (Select THREE).

  A. Using the device as a Wi-Fi hotspot

  B. A cracked screen

  C. A failing battery

  D. Less than 15% free storage space on the phone

  E. Privileged control

  F. Recurring prompts to install OS updates

  G. Granting too many application camera permissions

  H. Too many open applications

  Correct Answer: ACH

  Using the device as a Wi-Fi hotspot, a failing battery, and too many open applications are the most likely causes of the cell phone getting hot. These actions require the phone to use more power and processing, causing it to heat up.

• Question 235:

  Which of the following commonly uses NFC?

  A. Contactless payments

  B. loT devices

  C. Inventory tracking

  D. Tethering

  Correct Answer: A

  Contactless payments commonly use NFC (Near Field Communication) technology. NFC allows two devices to communicate wirelessly when they are brought close together, typically within a few centimeters. Contactless payment systems, such as Apple Pay, Google Wallet, and Samsung Pay, use NFC to securely transmit payment information between a smartphone or smartwatch and a payment terminal. While IoT devices, inventory tracking, and tethering may also use NFC, contactless payments are the most common use case.

• Question 236:

  A user working in the field reported the GPS stopped working on a phone. The user's older, in-car GPS continued to function. Later, the user reported that the phone's GPS started working again. Which of the following MOST likely caused the phone's GPS to fail?

  A. The cell phone was in conservation mode

  B. The cell phone had lost service to the earner

  C. The eel phone received a firmware update

  D. The cell phone had overheated

  Correct Answer: B

  The phone's GPS may fail due to a loss of service from the carrier, which provides the phone with GPS location data. The fact that the in-car GPS continued to function suggests that the issue was related to the phone, not the GPS satellites. References: CompTIA A+ Certification Study Guide, Tenth Edition, pg. 372

• Question 237:

  Recently, an organization received a number of spam emails that passed through the spam gateway. The emails contained generally the same information, but the sending domains were different. Which of the following solutions would BEST help mitigate the issue?

  A. Updating the keyword filtering

  B. Editing the sender policy framework

  C. Contacting the gateway vendor

  D. Verifying DMARC is enabled

  Correct Answer: A

• Question 238:

  A technician installed a new router at a small office. After the Installation, the technician notices that all devices have a I69.254.x.x IP address. Printers and fileshares are still working, but PCs cannot access the Internet. Which of the following should the technician configure on the router to enable devices to connect to the internet?

  A. APIPA

  B. DNS

  C. DHCP

  D. SMB

  Correct Answer: C

  To enable devices to connect to the internet after installing a new router at a small office, the technician should configure DHCP (Dynamic Host Configuration Protocol) on the router. DHCP is a network protocol that automatically assigns IP addresses and other network configuration parameters to devices on a network. By configuring DHCP on the router, the technician can ensure that all devices on the network are assigned a valid IP address that allows them to connect to the internet. If all devices have a 169.254.x.x IP address, this suggests that the router is not assigning IP addresses to the devices using DHCP (Dynamic Host Configuration Protocol). Configuring the DHCP settings on the router can enable the devices to receive IP addresses automatically and access the internet.

• Question 239:

  A technician is installing new power supplies for the application engineering team's workstations. The management team has not yet made a decision about installing dual graphics cards, but they want to proceed with the project anyway. Which of the following power supplies would provide the BEST solution?

  A. 1000W 24-pin modular power supply

  B. 220VAC 9000J surge protector

  C. 500W redundant power supply

  D. 2000VA uninterruptible power supply

  Correct Answer: A

  A 1000W 24-pin modular power supply provides enough power to support a dual graphics card configuration, which requires a significant amount of power. A modular power supply allows the technician to connect only the cables that are necessary for the current configuration, reducing cable clutter and improving airflow inside the case. This makes it easier to install and maintain the power supply.

• Question 240:

  A technician receives a ticket that states a mobile payment device is having Issues with Its contactless payment feature. The device is not detecting payment options. Which of the following Is the MOST likely cause of the Issue?

  A. NFC

  B. Bluetooth

  C. Wi-Fi

  D. Lightning adapter

  Correct Answer: A

  NFC (Near Field Communication) is the technology used for contactless payment features on mobile payment devices. If a mobile payment device is having issues with its contactless payment feature and is not detecting payment options, it is most likely due to an issue with the NFC functionality of the device. The contactless payment feature on a mobile payment device uses NFC (Near Field Communication) to detect payment options. If the device is not detecting payment options, the issue may be related to a problem with the NFC feature. References: https://www.techopedia.com/definition/31790/near-field-communication-nfc
