CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 141:

  Which of the following cloud models maintains access, even when a local internet outage occurs?

  A. Private

  B. SaaS

  C. Community

  D. Public

  Correct Answer: A

  In a private cloud model, the cloud infrastructure is maintained within a company's own data center and is used exclusively by that company. Private clouds offer the advantage of maintaining access even when a local internet outage occurs,

  since the cloud infrastructure is not dependent on a public network connection. Software as a Service (SaaS) is a cloud model in which software applications are hosted by a third-party provider and made available to customers over the

  internet. SaaS is not designed to maintain access in the event of a local internet outage. A community cloud is a shared infrastructure that is used by multiple organizations, typically from the same industry or with similar requirements.

  Community clouds are not designed to maintain access in the event of a local internet outage. A public cloud is a cloud infrastructure that is maintained by a third-party provider and is made available to the public over the internet. Public

  clouds are not designed to maintain access in the event of a local internet outage.

• Question 142:

  A user is installing a new display on a desktop computer that only has a single DVI port for video input and a single HDMI port tot video output.

  Which of me following does the technician need to complete the setup?

  A. DigitaMo-analog converter

  B. A/v switcher

  C. DisplayPort to HDMI adapter

  D. DVI to HDMI cable

  Correct Answer: D

  The technician will need to connect the DVI port on the computer to the new display's HDMI port. To do this, a DVI to HDMI cable will be needed. This type of cable will allow the computer's DVI video signal to be transmitted to the new

  display's HDMI port. A digital-to-analog converter (DAC) is used to convert a digital signal to an analog signal. An A/V switcher is used to switch between multiple audio and video sources and display them on a single monitor or display. A

  DisplayPort to HDMI adapter is used to convert a DisplayPort signal to an HDMI signal, but it is not necessary in this scenario as the computer has a DVI port and not a DisplayPort.

• Question 143:

  A technician recently received a written warning for causing a system-wide outage. The outage was a result of an unscheduled patch being manually pushed during production hours. Which of the following could have MOST likely prevented the technician from receiving the warning?

  A. Following corporate procedures

  B. Testing before deployment

  C. Documenting the findings

  D. Establishing a plan of action

  Correct Answer: A

  Following corporate procedures would have been the most likely factor that could have prevented the technician from receiving the written warning. Following established procedures, such as change management, helps ensure that changes made to the production environment are thoroughly tested, approved, and implemented in a controlled and safe manner, reducing the risk of system-wide outages and other unintended consequences.

• Question 144:

  A user's laptop is running out of disk space and requires a new hard drive. The user wants to replace the existing hard drive with the fastest possible I TB HDD. A technician assesses the user's hardware and determines the connections that are available.

  Which of the following drive types should the technician recommend as the BEST choice?

  A. 1TB NVMe SSD

  B. 1TB flash drive

  C. 1TB SATA SSD

  D. 1TB SAS

  Correct Answer: A

  The best choice for the user's laptop is a 1TB NVMe SSD. NVMe (Non- Volatile Memory Express) is a high-performance storage protocol designed specifically for solid-state drives (SSDs). It is significantly faster than SATA SSDs and SAS hard drives, making it ideal for users who need fast storage for their laptop. NVMe SSDs also have lower latency and higher bandwidth than traditional hard drives, making them well-suited for data-intensive tasks such as video editing, gaming, and running multiple applications simultaneously. Additionally, NVMe offers more reliable data reliability than traditional hard drives, and is less susceptible to performance degradation over time.

• Question 145:

  A desktop support technician is building a new desktop that features the fastest internal storage. Which of the following BEST suits this request1?

  A. SATASSD

  B. SATA HDD

  C. M2PCIeNVMeSSD

  D. PCIe SATA HDD

  Correct Answer: C

  M2PCIeNVMeSSD. M.2 PCIe NVMe SSDs are the fastest internal storage devices available for desktops. They are faster than SATA SSDs and PCIe SATA HDDs12.

• Question 146:

  A technician is troubleshooting an issue involving lines appearing down copied pages, but printed pages sent directly to the copier render as intended. Which of the following is the MOST likely cause of this issue?

  A. Empty imager drum

  B. Overheated system fuser

  C. Scratched scanner glass

  D. Third-party toner

  Correct Answer: C

  If lines appear down copied pages but printed pages sent directly to copier render as intended, it could be due to scratched scanner glass which can cause lines or streaks on copied pages.

  If there are lines appearing on copied pages, but not on printed pages sent directly to the copier, the issue is most likely caused by a scratch on the scanner glass.

• Question 147:

  Which of the following options provides correct information about 2.4GHz and 5GHz wireless frequencies? (Select TWO)

  A. 2.4GHz has less interference. 5GHz transmits inlower speed.

  B. 2.4GHz penetrates solid objects more effectively. 5GHz provides faster data connections.

  C. 2.4GHz has a higher data rate. 5GHz has 23 channels.

  D. 2.4GHz has Il channels. 5GHz has no data interference.

  E. 2.4GHz has a higher coverage area. 5GHz has higher bandwidth.

  F. 2.4GHz has a higher bandwidth. 5GHz has lower transmit power.

  Correct Answer: BE

  The correct answers are B. 2.4GHz penetrates solid objects more effectively. 5GHz provides faster data connections and E. 2.4GHz has a higher coverage area. 5GHz has higher bandwidth. The 2.4GHz frequency has a lower data rate compared to 5GHz, but it can penetrate solid objects more effectively and has a higher coverage area. The 5GHz frequency, on the other hand, provides faster data connections and has higher bandwidth, but it has fewer channels and lower transmit power.

• Question 148:

  A technician has set up a new conference room with a TV and a video soundbar. The technician wants to test the system with a conference call. During the test, the TV speaker produces sound, but the soundbar does not. Which of the following is the MOST likely cause of the issue?

  A. The volume on the TV needs to be turned up

  B. The conference call needs to be unmuted for audio.

  C. An incorrect HDMI cable is being used.

  D. The TV's HDMI-ARC port is not being used.

  Correct Answer: D

  HDMI-ARC (Audio Return Channel) is an HDMI connection that allows audio to be sent from the TV to an external sound system, such as a soundbar. If the TV's HDMI-ARC port is not being used, then the soundbar will not receive any audio from the TV and thus will not produce any sound. To resolve the issue, the technician should ensure that the TV's HDMI-ARC port is being used to connect the TV to the soundbar.

• Question 149:

  An insurance company wants to implement cloud computing and would like a cloud solution in which the infrastructure is shared with businesses in the same industry. Which of the following cloud models BEST addresses the company's need?

  A. Community

  B. Private

  C. Public

  D. Hybrid

  Correct Answer: A

  In a hybrid cloud model, the infrastructure is shared between public cloud services and an on-premise private cloud. This means that the insurance company can benefit from the scalability and cost-effectiveness of public cloud services, while also having the control and security of a private cloud. This allows the company to access resources that are specialized to their industry, while also ensuring that their data and infrastructure are kept secure.

• Question 150:

  A technician needs to install RAM into a rackmount server that will be used as a VM host. Which of the following would be BEST to install?

  A. SODIMM

  B. VRAM

  C. DDR4

  D. ECC

  Correct Answer: D

  When installing RAM into a server that will be used as a VM host, it is recommended to install ECC (Error-Correcting Code) RAM to help prevent errors that can cause virtual machines to crash. References: https://www.servermonkey.com/
