CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 651:

  A technician is configuring a desktop RAID to allow for the best I/O performance and the most storage capacity possible. Which of the following RAID types should the technician use?

  A. 10

  Correct Answer: A

  Explanation: RAID 0 is a disk array configuration that splits data across two or more disks without parity or mirroring. RAID 0 provides the best I/O performance because it allows parallel read and write operations on multiple disks. RAID 0 also provides the most storage capacity possible because it does not use any disk space for redundancy. However, RAID 0 does not provide any fault tolerance and increases the risk of data loss if any disk fails. References: The Official CompTIA A+ Core 1 Student Guide (Exam 220-1101) eBook, page 252

• Question 652:

  A company wants to save money by leveraging the cloud while still being able to customize the infrastructure. Which of the following cloud models would best address the company's needs?

  A. Private

  B. Public

  C. Hybrid

  D. Community

  Correct Answer: C

  Explanation: A hybrid cloud model would best address the company's needs of saving money by leveraging the cloud while still being able to customize the infrastructure. A hybrid cloud model is a combination of public and private cloud services, connected by a secure network. A public cloud service is a cloud service that is offered by a third-party provider over the Internet, and is shared by multiple customers. A private cloud service is a cloud service that is dedicated to a single customer, and is hosted either on-premises or by a third-party provider. A hybrid cloud model allows the company to use the public cloud for cost-effective and scalable services, such as storage, backup, or analytics, and use the private cloud for more sensitive or customized services, such as security, compliance, or performance. A hybrid cloud model also enables the company to move workloads between the public and private cloud as needed, depending on the demand, availability, or cost. A hybrid cloud model can provide the company with the best of both worlds: the flexibility and efficiency of the cloud, and the control and customization of the infrastructure.

• Question 653:

  Which of the following is the best example of when to use virtualization?

  A. To manage shared folders by user accounts

  B. To deploy software updates to user machines

  C. To enhance security by centralizing all user desktops

  D. To prevent users from circumventing password policies

  Correct Answer: C

  One of the benefits of virtualization is that it allows you to create and manage multiple virtual machines (VMs) on a single physical computer. This can be used to enhance security by centralizing all user desktops on a server, rather than storing them on individual user machines. This way, the user desktops can be isolated from each other and from the host machine, preventing malware infections, data breaches, and unauthorized access. Additionally, the user desktops can be easily backed up, restored, updated, and monitored by the administrator, reducing the risk of data loss and downtime. This type of virtualization is called desktop virtualization, and it separates the desktop environment from the physical hardware the user interacts with1. The user can access their virtual desktop from any device, such as a laptop, tablet, or smartphone, using a remote display protocol. The user experience is similar to using a local desktop, but with improved security and manageability.

• Question 654:

  A user would like a removable storage device that is secure. portable, and does not contain moving parts. Which of the following devices would be the most suitable?

  A. HDD

  B. NAS

  C. SSD

  D. SAN

  Correct Answer: C

  Explanation: An SSD (solid state drive) is a removable storage device that uses flash memory to store data. It is secure, portable, and does not contain moving parts, which makes it more reliable and durable than other types of storage

  devices. An HDD (hard disk drive) is not suitable, as it contains spinning platters and read/write heads that are prone to damage and data loss. A NAS (network attached storage) and a SAN (storage area network) are not removable devices,

  as they are connected to a network and provide shared storage for multiple users.

• Question 655:

  In a SOHO environment, a user wants to make sensitive, scanned documents available to other users on the domain. The logs need to indicate who accessed the documents and at what time they were accessed. Which of the following settings should a technician set up on the MFP device?

  A. Scan to email

  B. ADF tray

  C. PCL

  D. SMB share

  Correct Answer: D

  Explanation: The correct answer is D. SMB share.

  SMB stands for Server Message Block, which is a network protocol that allows file and printer sharing among different devices on a local area network (LAN). An SMB share is a folder or drive that is shared using the SMB protocol and can be accessed by authorized users on the network. An MFP device is a multifunction printer that can perform multiple tasks, such as printing, scanning, copying, and faxing. In a SOHO (small office/home office) environment, a user who wants to make sensitive, scanned documents available to other users on the domain can set up an SMB share on the MFP device. This way, the user can scan the documents to the SMB share and grant access permissions to the other users who need to view or edit them. The SMB share can also enable logging, which can record who accessed the documents and at what time they were accessed . The other options are not the best settings for this scenario. Scan to email is a feature that allows the user to scan a document and send it as an email attachment to a recipient. This option may not be secure or convenient for sharing sensitive documents with multiple users on the domain. ADF tray stands for automatic document feeder tray, which is a component of an MFP device that can feed multiple pages of a document into the scanner or copier without manual intervention. This option is not related to sharing or logging scanned documents. PCL stands for Printer Command Language, which is a page description language that controls the layout and printing of documents. This option is not related to sharing or logging scanned documents either.

• Question 656:

  A technician is using a PAN to connect a group of users on a field project. Which of the following services should the technician activate on the mobile device to share the internet data connection?

  A. Tethering

  B. Pairing

  C. Bluetooth

  D. Hotspot

  Correct Answer: D

  To share the internet data connection with a group of users on a field project, the technician should activate the hotspot feature on the mobile device. Hotspot functionality allows the device to act as a wireless access point, enabling other devices to connect to it and share its internet connection. Tethering is a similar concept but often refers to connecting a device to another via USB or Bluetooth to share the internet connection. In this context, hotspot (option D) is the most appropriate choice for connecting a group of users.

• Question 657:

  A technician wants to stress test multiple applications while maintaining the ability to easily reset those environments back to the initial state. Which of the following is the best way to accomplish this task?

  A. Honeypot

  B. Hybrid cloud

  C. Sandbox

  D. Production network

  Correct Answer: C

• Question 658:

  Which of the following services allows a remote user to access network resources?

  A. WLAN

  B. SAN

  C. DHCP

  D. VPN

  Correct Answer: D

  Explanation: The correct answer is D. VPN.

  A VPN (Virtual Private Network) is a service that allows a remote user to access network resources securely over the internet. A VPN creates an encrypted tunnel between the user's device and the VPN server, which acts as a gateway to the network. The user can then access the network resources as if they were directly connected to the network, without exposing their traffic to eavesdropping, interception, or censorship. A VPN can provide remote users with access to various services on a company network, such as file and print services, client/server applications, and remote network administration1. A VPN can also protect the user's privacy and identity online by masking their IP address and location.

• Question 659:

  An administrator is replacing a cable that uses a DB9 connector VVhich of the following cables is the administrator replacing?

  A. Parallel

  B. Serial

  C. Optical

  D. USB

  Correct Answer: B

  Explanation: The correct answer is B. Serial. A serial cable is a type of cable that can be used to connect devices that use serial communication, which is a method of sending data one bit at a time over a single wire. Serial cables are often used for console access to network devices, such as routers, switches, firewalls, or servers, when other methods of connection, such as SSH (Secure Shell), are not available or not working. A DB9 connector is a type of connector that has nine pins and is commonly used for serial cables. DB stands for D-subminiature, which is a family of connectors that have a D- shaped metal shield and different numbers of pins. DB9 connectors are also known as DE- 9 connectors, as they belong to the E size category of Dsubminiature connectors. DB9 connectors can support various serial standards, such as RS-232, RS-422, or RS-485. A parallel cable is a type of cable that can be used to connect devices that use parallel communication, which is a method of sending data multiple bits at a time over multiple wires. Parallel cables are often used for connecting printers or scanners to computers, but they are not commonly used for network devices or serial connections. An optical cable is a type of cable that can be used to transmit data using light signals over fiber-optic strands. Optical cables can offer high-speed, high-bandwidth, and low- interference data transmission over long distances. Optical cables are often used for network communication, such as Ethernet, or audio/video transmission, such as HDMI or TOSLINK. A USB cable is a type of cable that can be used to connect devices that use the Universal Serial Bus (USB) standard, which is a protocol that allows data and power transmission between devices. USB cables can support various types of devices, such as keyboards, mice, cameras, flash drives, or chargers. USB cables have different versions and connectors, such as USB-A, USB-B, USB-C, or Micro-USB. Therefore, the only cable that uses a DB9 connector is a serial cable.

• Question 660:

  A technician is troubleshooting a phone with limited internet connectivity. The technician has identified the phone on the Wi-Fi network and confirmed that it responds to pings. However, the phone is still unable to open comptia.org. Which of the following should the technician check next?

  A. Jailbreak status

  B. DNS servers

  C. Airplane mode

  D. Certificate store

  Correct Answer: B

  DNS servers are responsible for translating domain names into IP addresses, which are used to access websites. If the phone has limited internet connectivity, it might be because the DNS servers are not working properly or are blocked by the network. The technician should check the DNS settings on the phone and try to use a different DNS server, such as Google DNS (8.8.8.8 or 8.8.4.4) or Cloudflare DNS (1.1.1.1 or 1.0.0.1).
