CompTIA 220-1201 Online Questions & Answers

• Question 271:

  A technician has been called into a conference room to help with a video call setup. The user is unable to get the laptop screen to mirror to the in-room television. The technician confirms that the appropriate HDMI cable is plugged into the user's computer, and the TV has a blinking logo on the screen.

  Which of the following is most likely causing the issue?

  A. The user's laptop does not support screen mirroring.
  B. The television does not support screen mirroring.
  C. The wrong input is selected on the television.
  D. The user does not have Bluetooth enabled on the laptop.
  E. The television has a defective A/C adapter cable.
  C. The wrong input is selected on the television.

  ---

  Explanation

  When a laptop screen fails to mirror to a television despite being correctly connected via an HDMI cable, the most likely issue is that the television is set to the wrong input source. Modern televisions have multiple input options (e.g., HDMI 1, HDMI 2, AV), and selecting the correct input that matches the port the HDMI cable is connected to is critical for displaying the laptop's screen. The blinking logo on the TV screen suggests the TV is operational but not receiving a signal from the selected input source. Changing the TV's input to the appropriate HDMI port should resolve the issue and allow the laptop screen to mirror onto the TV.

• Question 273:

  Which DNS record is used by DMARC to verify the authenticity of email servers?

  A. MX
  B. CNAME
  C. TXT
  D. A
  C. TXT

  ---

  Explanation

  CompTIA A+ explains that DMARC (Domain-based Message Authentication, Reporting, and Conformance) relies on TXT DNS records to define its policies. TXT records allow administrators to publish arbitrary text-based configuration data, including DKIM and SPF policies, which DMARC references.

  MX records identify mail servers, A records map IP addresses, and CNAME records create aliases none are used to store DMARC policy rules.

  DMARC improves email authenticity by requiring SPF and DKIM alignment and specifying how receiving servers should handle failed validations. The A+ exam explicitly mentions TXT records as the method used for SPF, DKIM, and DMARC storage.

  Therefore, the correct answer is the TXT record, which stores the policy used by DMARC to authenticate senders and prevent spoofing.

• Question 274:

  A company needs to keep a record of tasks performed by an application.

  Which of the following should the company most likely implement as part of a solution?

  A. Fileshare
  B. Syslog
  C. Database
  D. SAN
  B. Syslog

  ---

  Explanation

  Syslog is used to log system events and tasks performed by applications, providing a centralized record of activity.

  Why Not A (Fileshare): Fileshares store files but are not designed for event logging.

  Why Not C (Database): Databases can store logs but are not a logging mechanism themselves.

  Why Not D (SAN): A SAN is a storage solution, not a logging tool.

• Question 275:

  Which of the following are radio frequency connections? (Select two.)

  A. Cable
  B. Satellite
  C. DSL
  D. Cellular
  E. Ethernet
  F. Fiber
  B. Satellite
  D. Cellular

  ---

  Explanation

  CompTIA A+ explains that radio frequency (RF) connections use electromagnetic waves instead of copper or optical cabling. Satellite uses RF signals transmitted to and from orbiting satellites, while cellular networks (3G/4G/5G) use RF communications via cell towers.

  Cable uses coaxial wired infrastructure, DSL uses telephone lines, Ethernet is twisted-pair copper, and fiber uses light instead of RF.

  Satellite and cellular are the only technologies in the list that rely on wireless radio frequency transmission as their medium. The A+ networking domain emphasizes understanding the physical media of WAN technologies and distinguishing wired vs. wireless connectivity, making B and D the correct answers.

• Question 276:

  A technician is asked to set up a new laptop for a coworker.

  Which of the following storage devices and interfaces will provide the best performance?

  (Select two).

  A. 15,000rpm HDD
  B. M.2 SSD
  C. 10,000rpm HDD
  D. NVMe interface
  E. SATA interface
  F. mSATA interface
  B. M.2 SSD
  D. NVMe interface

  ---

  Explanation

  M.2 SSD and NVMe interface are the best options for storage devices and interfaces that provide the best performance. M.2 SSD is a form factor that allows for faster data transfer and lower power consumption than traditional SATA SSDs.

  NVMe is a protocol that enables direct communication between the SSD and the PCIe bus, bypassing the SATA controller and reducing latency and overhead. Together, they offer the highest speed and efficiency for storage devices.

• Question 277:

  Which of the following is used to implement PoE?

  A. Modem
  B. Range extender
  C. Media converter
  D. Injector
  D. Injector

  ---

  Explanation

  Power over Ethernet (PoE) allows network cables to carry electrical power to devices such as wireless access points, IP cameras, and VoIP phones, eliminating the need for separate power supplies. According to the CompTIA A+ Core 1 220-1201 objectives under Networking, PoE can be implemented in the following ways:

  PoE-enabled switches: Switches that can supply power directly over the Ethernet ports. PoE injectors: Devices that add power to an existing Ethernet connection when the switch or router does not provide PoE.

  Why the other options are incorrect:

  A. Modem: A modem connects a network to the Internet but does not provide PoE functionality.

  B. Range extender: Extends the range of a wireless network; does not supply power over Ethernet.

  C. Media converter: Converts one type of network media to another (e.g., fiber to copper) but does not implement PoE. Therefore, when a switch does not natively provide PoE, a PoE injector is the standard solution to add power to the Ethernet line.

• Question 278:

  Which of the following cable types is a video-only connection?

  A. DisplayPort
  B. HDMI
  C. USB-C
  D. DVI
  D. DVI

  ---

  Explanation

  The correct answer is D. DVI (Digital Visual Interface).

  According to CompTIA A+ Core 1 220-1201 objectives under Hardware and Display Technologies:

  DVI is primarily a video-only interface that transmits digital or analog video signals from a source (like a computer) to a display.

  Unlike HDMI or USB-C, DVI does not carry audio signals, making it strictly for video.

  Why the other options are incorrect:

  A. DisplayPort: Supports video and audio as well as other features such as daisy-chaining multiple monitors.

  B. HDMI: Transmits both video and audio signals over a single cable.

  C. USB-C: Can carry data, power, and video/audio signals depending on the device and protocol (e.g., DisplayPort Alt Mode).

• Question 279:

  Which of the following models is an example of metered utilization?

  A. Reserved instance
  B. Pay-as-you-go
  C. Subscription-based
  D. Multitenant
  B. Pay-as-you-go

  ---

  Explanation

  Metered utilization is a pricing model for cloud computing services, where the customer pays only for the amount of resources that are consumed, such as CPU time, memory, storage, bandwidth, etc. The customer is billed based on the actual usage of the resources, rather than a fixed or upfront fee. Metered utilization is also known as usage-based pricing or pay-per-use 12. Pay-as-you-go is an example of metered utilization, where the customer pays for the cloud resources on demand, without any long-term commitment or contract. The customer can scale up or down the resources as needed, and only pay for what is used. Pay-as-you-go is a flexible and cost-effective option for customers who have unpredictable or variable workloads, or who want to try out new services or features 12. The other options are not examples of metered utilization. Reserved instance is a pricing model where the customer pays a discounted rate for a fixed amount of cloud resources for a specified period of time, such as one or three years. The customer can reserve the resources in advance, and benefit from lower costs and guaranteed availability. Reserved instance is suitable for customers who have predictable or steady workloads, or who want to optimize their budget 12. Subscription-based is a pricing model where the customer pays a fixed fee for a set of cloud services or features for a certain period of time, such as monthly or annually. The customer can access the services or features as much as needed, without worrying about the usage or consumption of the resources. Subscription-based is suitable for customers who want to have a consistent and predictable cost, or who want to access premium or exclusive services or features 12. Multitenant is not a pricing model, but a cloud architecture where multiple customers share the same physical or virtual resources, such as servers, databases, applications, etc. The resources are isolated and secured for each customer, and the customers can benefit from lower costs, higher scalability, and faster updates. Multitenant is a common characteristic of public cloud services, where the cloud provider manages and maintains the resources for the customers 12.

• Question 280:

  A network administrator must ensure that a printer will still be assigned a specific IP address even if all addresses are depleted.

  Which of the following network configuration concepts is this describing?

  A. VLAN
  B. Lease
  C. Reservation
  D. Exclusion
  C. Reservation

  ---

  Explanation

  A DHCP reservation binds a specific MAC address to an IP address so the device always receives the same IP from the DHCP server. This ensures network devices like printers maintain consistent connectivity and availability even when the

  IP pool is low.
