CompTIA 220-1101 Online Questions & Answers

• Question 21:

  A technician is implementing a RAID array for the financial department. The solution should allow fast access to data and maximum redundancy.

  Which of the following RAID configurations best meets these requirements?

  B. 1
  C. 5
  D. 10
  D. 10

  ---

  Explanation

  RAID 10 (also known as RAID 1+0) combines the features of RAID 1 (mirroring) and RAID 0 (striping) to provide both redundancy and performance enhancements. This configuration requires a minimum of four drives and offers fast data access through striping while ensuring data redundancy through mirroring. RAID 10 is ideal for environments where both data integrity and performance are critical, such as financial databases.

• Question 22:

  A technician needs to install a cost-effective storage device into a rackmount server that will be used as a VM host. This storage will be used for all VMs that run from the server. Which of the following should be used?

  A. Optical disk drive
  B. eMMC storage device
  C. 15,000rpm drive
  D. RAID 10 array
  C. 15,000rpm drive

  Explanation

• Question 23:

  Which of the following is a method that can be used to securely connect a remote user's laptop to a corporate server?

  A. WAN
  B. VPN
  C. SSL
  D. DHCP
  B. VPN

  ---

  Explanation

  A Virtual Private Network (VPN) is a secure method for connecting a remote user's laptop to a corporate server. VPNs use encryption to protect data transmitted over the internet.

• Question 24:

  A technician needs to ensure all data communications on all network devices are encrypted when logging in to the console. Which of the following protocols should the technician enable?

  A. SSH
  B. LDAP
  C. FTPS
  D. SMTP
  A. SSH

  ---

  Explanation

• Question 25:

  A user reports that a PC occasionally falls to boot. The user reboots the PC. but the performance is degrading. The technician hears a strange, repetitive, ticking noise coming from the PC. Which of the following should the technician do FIRST?

  A. Try to extract data.
  B. Reseat the RAM modules.
  C. Inspect the fan.
  D. Check the CD tray.
  A. Try to extract data.

  ---

  Explanation

  This is a safe and sensible option if you value your data more than anything else. You don't want to risk losing your data by trying other methods that may worsen the situation. You can use a software tool or a service provider to recover your data before attempting any repairs.

• Question 26:

  A user's laptop is experiencing severe slowdowns when operating process-intensive tasks. Which of the following memory upgrades is compatible with a laptop?

  A. DIMM
  B. ECC RAM
  C. Virtual RAM
  D. SODIMM
  D. SODIMM

  ---

  Explanation

  SODIMM stands for Small Outline Dual In-line Memory Module and is a type of memory module that is compatible with laptops and other small devices. SODIMMs are smaller and thinner than DIMMs (Dual In-line Memory Modules), which are typically used for desktop PCs and servers. Upgrading or adding SODIMMs can increase the amount of RAM available for a laptop, which can improve its performance and speed when running process-intensive tasks.

• Question 27:

  A network technician needs to provide better wireless connectivity throughout a SOHO location. Which of the following should the technician deploy to best improve connectivity?

  A. Access point
  B. Managed switch
  C. POE hub
  D. Wi-Fi router
  A. Access point

  ---

  Explanation

  The correct answer is A. Access point. An access point is a device that extends the wireless coverage of a network by creating a hotspot that allows wireless devices to connect to the network1. An access point can be connected to a router or a switch via an Ethernet cable or a wireless bridge1. By deploying one or more access points throughout a SOHO location, the technician can provide better wireless connectivity and eliminate dead zones or weak signals2. A managed switch is a device that allows multiple devices to communicate on a network by forwarding data packets based on their destination addresses3. A managed switch can also provide advanced features such as VLANs, QoS, security, and remote management3. However, a managed switch does not improve wireless connectivity, as it only works with wired devices. A POE hub is a device that provides power and data over a single Ethernet cable to devices that support Power over Ethernet (PoE) technology, such as IP cameras, VoIP phones, and wireless access points4. A POE hub can simplify the installation and placement of these devices by eliminating the need for separate power adapters or outlets4. However, a POE hub does not improve wireless connectivity by itself, as it still requires an access point or a router to create a wireless network. A Wi-Fi router is a device that combines the functions of a router and an access point, providing both wired and wireless connectivity to a network and the internet. A Wi-Fi router can be used to create a SOHO network, but it may not be sufficient to cover the entire location with a strong and reliable wireless signal. To improve wireless connectivity, the technician may need to add additional access points or use a mesh Wi-Fi system that consists of multiple routers that work together to create a seamless wireless network. Therefore, an access point is the best option among the choices to improve wireless connectivity throughout a SOHO location.

• Question 28:

  An administrator needs to configure RAID for a video-rendering workstation at minimal cost. The solution should have high read/write performance and maximum drive storage utilization. Redundancy is not a concern. Which of the following RAID configurations should the administrator use?

  B. 1
  C. 5
  D. 10
  A

  ---

  Explanation

  The administrator should use RAID 0 for a video-rendering workstation at minimal cost. RAID 0, also known as striping, is a RAID configuration that splits data evenly across two or more disks, without parity information, redundancy, or fault tolerance. RAID 0 has the following advantages and disadvantages: High read/write performance: RAID 0 can increase the data transfer rate by using multiple disks in parallel. This can improve the speed and efficiency of video rendering, which involves processing large amounts of data. RAID 0 can also reduce the latency and seek time of the disks, as the data is distributed across multiple spindles. Maximum drive storage utilization: RAID 0 can use the full capacity of the disks, without wasting any space for parity or mirroring. This can lower the cost and increase the storage space for the workstation. For example, if two 500 GB disks are used in RAID 0, the total capacity of the array will be 1000 GB. No redundancy or fault tolerance: RAID 0 does not provide any protection against data loss or disk failure. If one disk fails, the entire array will fail and the data will be unrecoverable. Therefore, RAID 0 should only be used for non-critical data that is backed up elsewhere, or for temporary files that can be recreated.

• Question 29:

  Which of the following components enables the input on a mobile device's touch screen?

  A. OLED
  B. Digitizer
  C. Inverter
  D. CMOS sensor
  B. Digitizer

  ---

  Explanation

  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.

• Question 30:

  A technician is configuring a workstation to be used as a VM host. After installing the necessary software, the technician is unable to create any VMs. Which of the following actions should be performed?

  A. Disable the BIOS password.
  B. Enable TPM.
  C. Enable multithreading.
  D. Enable Fast Startup.
  C. Enable multithreading.

  ---

  Explanation

  TPM is not a requirement to start VMs. People are assuming information that is not in the question and this is usually the cause of second guessing these kinds of exams for most test takers. The question states nothing about Windows 11. In order to have a VM running on a system, the system needs to have hyperthreading and/or multicore processing. I work with VMs on a regular basis. TPM is used for encryption purposes of a drive and is required for Windows 11 installations, but again, where in the question does it state Windows 11 and not something like Ubuntu, or any other OS for that matter?
