   Which of the following DNS records is used to look up the IP address assigned to a domain name?

   • AA
   • BMX
   • CNS
   • DSPF

   Show answer

   Answer: A

   Explanation

   The DNS record used to look up the IP address assigned to a domain name is: A. A (Address) record. The A record maps a domain name to an IPv4 address. When a user enters a domain name into a web browser or other network application, the A record is queried to determine the corresponding IPv4 address of the server hosting that domain.

   A company recently enabled two-factor authentication in order to enhance security. Users should be prompted for two-factor authentication when working outside of the office, but are also being prompted when connecting to the office Wi-Fi. Which of the following should the technician do?

   • ALeave the current rules in place and disable Wi-Fi on all devices.
   • BImplement allow listing and add the office IP address as an exception.
   • CRemove two-factor authentication from the users’ accounts.
   • DSubstitute hard tokens in place of soft tokens.

   Show answer

   Answer: B

   Explanation

   B. Implement allow listing and add the office IP address as an exception. Allow listing (also known as whitelisting) involves specifying trusted IP addresses or ranges from which users can access resources without being prompted for two-factor authentication. By adding the office IP address as an exception to the two-factor authentication requirement, users connecting to the office Wi-Fi will not be prompted for two-factor authentication, while users working outside of the office will still be required to authenticate.

   Which of the following is an aspect of using client-side virtualization?

   • ACross-platform network support
   • BLegacy software support
   • CMultiuser software development
   • DMinimized resource consumption

   Show answer

   Answer: B

   Explanation

   An aspect of using client-side virtualization is: B. Legacy software support. Client-side virtualization allows users to run multiple virtual machines (VMs) on their local computer, enabling them to run different operating systems and software simultaneously. This capability is particularly useful for supporting legacy software that may require older operating systems or dependencies that are no longer compatible with the host system. By running legacy software in a virtual machine, users can maintain compatibility and access applications that would otherwise be incompatible with their current operating environment. Therefore, the correct answer is:

   • AMissing Wi-Fi adapter
   • BWi-Fi AP replacement
   • CHidden Wi-Fi SSID
   • DIncorrect Wi-Fi channel

   Show answer

   Answer: A

   Explanation

   A. Missing Wi-Fi adapter is the most likely reason. If the workstation was previously connected to a wired network and didn't require a Wi-Fi adapter, it's possible that the new location doesn't have one installed. GG

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

   • AWLAN
   • BSAN
   • CDHCP
   • DVPN

   Show answer

   Answer: D

   Explanation

   The service that allows a remote user to access network resources is: D. VPN (Virtual Private Network). A VPN creates a secure, encrypted connection over the internet between a remote user's device and the corporate network, allowing the user to access network resources as if they were directly connected to the network locally. VPNs are commonly used for remote access to internal corporate networks, enabling employees to work securely from remote locations while accessing files, applications, and other resources on the company's network. Therefore, the correct answer is: D. VPN.

   Which of the following technologies can be used to connect a home PC to a company's network?

   • AVLAN
   • BVM
   • CVPN
   • DVoIP

   Show answer

   Answer: C

   Explanation

   The technology used to connect a home PC to a company's network is: C. VPN (Virtual Private Network). A VPN allows a user to establish a secure, encrypted connection over the internet to the company's network, enabling remote access to network resources as if the user's device were physically connected to the company's internal network. This technology is commonly used to facilitate secure remote access for employees working from home or traveling, providing access to files, applications, and other resources on the company's network while maintaining security and privacy.

   Select 2

   A technician is setting up a home network with the following requirements: • Automatic distribution of IP addresses • Internet access Which of the following should the technician configure? (Choose two.)

   • ADHCP
   • BAPIPA
   • CVPN
   • DPublic IP addresses
   • EGateway
   • FStatic IP addresses

   Show answer

   Answer: AE

   Explanation

   To meet the requirements of automatic distribution of IP addresses and internet access in a home network, the technician should configure: A. DHCP (Dynamic Host Configuration Protocol) - DHCP automatically assigns IP addresses to devices on the network, ensuring that each device can communicate and access the internet without manual configuration. E. Gateway - The gateway is the device that connects the home network to the internet, typically a router. Configuring the gateway allows devices on the home network to access the internet through the gateway device. Therefore, the correct options are: A. DHCP E. Gateway

10. Question 400 · 624 in bank

    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?

    • A0
    • B5
    • C6
    • D10

    Show answer

    Answer: A

    Explanation

    The correct answer is A. The most storage capacity: This means maximizing the usable storage space available from the combined disks. For example, RAID 0 provides the most storage capacity because it uses all the disk space for data storage without reserving any for redundancy. Redundancy: This refers to the ability to withstand disk failures without data loss. Redundant RAID configurations, like RAID 1, RAID 5, RAID 6, and RAID 10, use part of the disk space to store duplicate or parity data, which can be used to recover data in case of a disk failure. This reduces the total usable storage capacity but increases data protection. In this context, the question specifically asks for "the most storage capacity," which aligns with RAID 0's characteristic of using all available disk space for data storage. RAID 0 doesn't provide redundancy, but it does offer the maximum possible storage capacity among the given options.
