CompTIA 220-1101 Online Questions & Answers

• Question 381:

  Which of the following cloud-computing concepts describes an application that is hosted on the internet but can be used and configured as needed internally per organization?

  A. Hybrid cloud
  B. Public cloud
  C. laaS
  D. SaaS
  E. PaaS
  D. SaaS

  ---

  Explanation

  Question states the application is "hosted on the internet" but "can be used and configured internally". This makes the answer D SAAS. You can configure and use the application from your desktop in the office even though the application is not hosted on your PC.

• Question 382:

  An administrator is configuring a corporate-owned smartphone for a new manager. The company requires the ability to wipe the phone's data remotely in the event of loss or theft and the capability to approve applications installed on the phone. Which of the following tools would BEST meet this need?

  A. Tethering to a corporate-owned laptop
  B. WPA2-Enterpise wireless
  C. Corporate enterprise email
  D. Mobile device management
  D. Mobile device management

  ---

  Explanation

  D. Mobile device management. A mobile device management (MDM) solution is specifically designed to provide centralized control over mobile devices and to help ensure the security and compliance of corporate data. An MDM solution can provide the ability to wipe the phone's data remotely in the event of loss or theft, and the capability to approve applications installed on the phone, which meets the requirements mentioned in the question.

  Tethering to a corporate-owned laptop, WPA2-Enterprise wireless, and corporate enterprise email can provide security and management capabilities, but they may not have the comprehensive control and management capabilities of a full-featured MDM solution.

• Question 383:

  A technician upgrades a PC with two DIMMs, for a total of 32GB. After installing the two DIMMs, the user notices the OS is reporting only 16GB.

  Which of the following tasks should the technician perform to resolve the issue in the most rapid, cost-effective way possible?

  A. Roll back recent system updates.
  B. Reinstall RAM in different slots.
  C. Update the OS to the latest version.
  D. Replace the faulty motherboard.
  B. Reinstall RAM in different slots.

  ---

  Explanation

  Reinstalling RAM in different slots addresses possible issues with dual-channel configurations. If not installed correctly, the system might not recognize the full capacity. This solution is immediate and doesn't incur extra costs, unlike replacing hardware. It reflects CompTIA A+ Core 1 exam objectives on hardware troubleshooting, specifically RAM installation and configuration.

• Question 384:

  A new VolP solution is being implemented at a corporate office for more than 200 users. The new VolP devices do not require AC adapters at the users' desks. Which of the following network devices should a technician purchase?

  A. Firewall
  B. Power injector
  C. PoE switch
  D. Router
  C. PoE switch

  ---

  Explanation

  The correct answer is

  C. PoE switch.

  A PoE switch is a network device that can provide both data and power to other devices over an Ethernet cable. PoE stands for Power over Ethernet, which is a technology that allows electrical power to be transmitted along with data on twisted pair Ethernet cabling. This eliminates the need for separate power supplies or AC adapters at the users' desks, as the VoIP devices can receive power from the PoE switch12. A firewall is a network device that monitors and controls incoming and outgoing network traffic based on predefined security rules. It does not provide power to other devices1. A power injector is a device that adds electrical power to an Ethernet cable for a single device. It is not suitable for a large number of devices, as it would require one power injector per device1. A router is a network device that connects multiple networks and forwards data packets between them. It does not provide power to other devices1.

• Question 385:

  A user's computer is not receiving a network connection. The technician confirms that the connection seems to be down and looks for the user's port on the patch panel. The port and patch panel are not labeled. Which of the following network tools should the technician use to identify the port?

  A. Network tap
  B. Punchdown tool
  C. Toner probe
  D. Crimper
  C. Toner probe

  ---

  Explanation

  Toner Probe Many cable testers also incorporate the function of a toner probe, which is used to identify a cable from within a bundle. This may be necessary when the cables have not been labeled properly. The tone generator is connected to the cable using an RJ45 jack and applies a continuous audio signal on the cable. The probe is used to detect the signal and follow the cable over ceilings and through ducts or identify it from within the rest of the bundle.

• Question 386:

  Which of the following can a user utilize to share their mobile phone connection with their laptop?

  A. IR
  B. NFC
  C. Wi-Fi Direct
  D. Tethering
  D. Tethering

  ---

  Explanation

  Tethering refers to sharing a mobile phone's internet connection with another device, such as a laptop, either through USB, Bluetooth, or Wi-Fi. Tethering effectively turns the mobile phone into a personal hotspot for internet access.

  Option A (IR): Incorrect. Infrared (IR) is used for short-range communication, such as remote controls, but it does not support internet sharing.

  Option B (NFC): Incorrect. Near-field communication (NFC) is used for close- proximity data transfer, not for internet sharing.

  Option C (Wi-Fi Direct): Incorrect. Wi-Fi Direct enables device-to-device communication but does not inherently provide internet sharing.

• Question 387:

  A user receives the following error when trying to reboot a computer:

  

  Which of the following is the MOST likely cause of this error message?

  A. Corrupted bootloader
  B. Faulty RAID controller
  C. Failed hard drive
  D. Incorrect storage device driver
  C. Failed hard drive

  ---

  Explanation

  The error message "Reboot and Select Proper Boot Device" indicates that the computer cannot find the boot device that contains the operating system12. This can happen if the hard drive that stores the operating system is damaged or failed, and the BIOS cannot detect it or read from it. A failed hard drive can also cause other symptoms such as clicking noises, corrupted files, or slow performance4.

• Question 388:

  Which of the following is a valid use for PaaS?

  A. Off-site backups
  B. An application development environment
  C. A virtual server installation and configuration model
  D. A web application for asset management
  B. An application development environment

  ---

  Explanation

  PaaS (Platform as a Service) is a cloud computing model in which a provider offers a platform that allows developers to create, run, and manage applications without the complexity of building and maintaining the infrastructure. An application development environment is a valid use for PaaS.

• Question 389:

  Which of the following utilizes TCP ports 20/21 and transfers data in cleartext?

  A. SNMP
  B. SSH
  C. FTP
  D. Telnet
  C. FTP

  ---

  Explanation

  FTP (File Transfer Protocol) uses TCP ports 20/21 and transfers data in cleartext, which means the data is not encrypted and can be read by anyone who intercepts it. This makes FTP insecure for transferring sensitive information. SSH (Secure Shell), on the other hand, uses port 22 and encrypts data, making it more secure. SNMP (Simple Network Management Protocol) uses ports 161/162 and is used to monitor network devices. Telnet uses port 23 and transfers data in cleartext, making it insecure.

• Question 390:

  A user is receiving many unsolicited emails. Which of the following controls can be configured to best reduce these types of emails?

  A. Load balancer
  B. Spam gateway
  C. Mail forwarding
  D. Proxy servers
  B. Spam gateway

  ---

  Explanation

  A spam gateway filters unsolicited emails at the server level, significantly reducing spam before it reaches user inboxes.

  Why Not A (Load balancer): Load balancers distribute traffic but don't filter spam.

  Why Not C (Mail forwarding): Forwarding doesn't filter spam.

  Why Not D (Proxy servers): Proxies control web traffic, not email filtering.
