• Question 42:

  A technician attempts to join a Windows client to a domain but receives the following error:

  An attempt to resolve the hostname has failed.

  The technician generates the display shown below utilizing ipconfig /all.

  

  Which of the following is the most likely reason for the error?

  A. DNS
  B. Physical address
  C. Subnet mask
  D. IPv4 address
  E. Default gateway
  A. DNS

  ---

  Explanation

  The most likely reason for the error is that the DNS server is not configured correctly. The technician should check the DNS server settings and make sure they are correct. DNS, or Domain Name System, is a service that translates domain names, such as www.example.com, into IP addresses, such as 192.168.1.1, that computers use to communicate with each other. DNS is essential for joining a Windows client to a domain, which is a logical group of computers that share a common directory and security policy. A domain name, such as example.com, identifies the domain and its members on the network. To join a Windows client to a domain, the client needs to resolve the hostname of the domain controller, which is the server that manages the domain and its resources. The client sends a DNS query to the DNS server, asking for the IP address of the domain controller. The DNS server responds with the IP address, and the client uses it to establish a connection with the domain controller and complete the domain join process. However, if the DNS server is not configured correctly, the client may not be able to resolve the hostname of the domain controller, and receive the error: An attempt to resolve the hostname has failed. This can happen if the DNS server is not reachable, not authoritative, or not updated. For example, the DNS server may have an incorrect IP address, a wrong DNS suffix, a missing or outdated DNS record, or a firewall blocking the DNS traffic. To fix the error, the technician should verify that the DNS server settings on the client and the domain controller are correct and consistent. The technician can use the ipconfig /all command to display the DNS server settings, such as the IPv4 address, the subnet mask, the default gateway, and the DNS suffix. The technician can also use the nslookup command to test the DNS resolution and the ping command to test the connectivity. The technician should make sure that the client and the domain controller are using the same DNS server, and that the DNS server can resolve the hostname of the domain controller.

• Question 44:

  Which of the following protocols can be used to securely access a remote network to troubleshoot various devices?

  A. FTP
  B. RDP
  C. SSH
  D. TFTP
  C. SSH

  ---

  Explanation

  SSH provides a secure, encrypted connection for remote access to network devices, servers, and other systems. It's widely used in network administration and troubleshooting tasks because it offers secure access to command-line interfaces and remote execution of commands on devices.

• Question 45:

  After dropping a mobile device, a user reports that it no longer responds to touch/tap commands. The user has already rebooted the device, but the issue persists. Which of the following components is MOST likely causing this issue?

  A. SIM card
  B. Charging port
  C. Digitizer
  D. Battery
  C. Digitizer

  ---

  Explanation

• Question 46:

  Which of the following handles touch-screen operation on a mobile device?

  A. Stylus
  B. Liquid crystal display
  C. Processor
  D. Digitizer
  D. Digitizer

  ---

  Explanation

  A digitizer is a component that handles touch-screen operation on a mobile device. It is a layer of material that detects and converts the touch of a finger or a stylus into an electrical signal that can be processed by the device12. A digitizer works with a display screen to create a touch-screen interface that allows a user to interact with the device by touching pictures or words on the screen.

• Question 47:

  A user reports that a laser printer continues to print pages with text that is too light to read even after adding additional toner. Which of the following should the technician replace to correct this issue?

  A. Paper with thinner stock
  B. Contrast sensor
  C. Pickup rollers
  D. Transfer drum
  D. Transfer drum

• Question 48:

  A technician is selecting a power supply for a new computer. There will be a large number of connected devices that must be powered by USB.

  Which of the following specifications should the technician prioritize?

  A. Modular connector count
  B. 5V amperage
  C. 20+4 power connector
  D. Energy efficiency
  B. 5V amperage

  ---

  Explanation

  USB devices rely on 5V output from the power supply, so the amperage rating at 5V is critical to ensure enough power is available for multiple USB devices. A modular connector count affects cable management, while a 20+4 power connector is standard for motherboard connections. Energy efficiency impacts overall power usage but is not specific to the needs of USB devices. This matches CompTIA A+ Core 1 objectives regarding power supply selection based on device requirements.

• Question 49:

  A help desk technician is tasked with moving a user's computer to a makeshift office for renovations. Upon moving the computer, the technician notices the network card will not utilize anything beyond 10Mbps half-duplex.

  Which of the following is the most likely issue?

  A. The computer is connected with DSL.
  B. The computer is connected to an unmanaged switch.
  C. The computer is configured for NIC teaming.
  D. The computer is connected to a hub.
  D. The computer is connected to a hub.

  ---

  Explanation

  Hubs operate in half-duplex mode and are limited to low speeds like 10Mbps, making them the most likely cause for the network card's performance issue.

  Why Not A (DSL): DSL relates to internet connectivity, not local network hardware.

  Why Not B (Unmanaged switch): Unmanaged switches typically support full-duplex and higher speeds than 10Mbps.

  Why Not C (NIC teaming): NIC teaming increases bandwidth and redundancy, and is not relevant to this issue.

• Question 50:

  A technician is configuring a SOHO network. During testing, the technician receives the IP address 169.254.2.2, but the router is assigned the address scope of 192.168.1.254/24. Which of the following is most likely the cause?

  A. DHCP
  B. Ipv6
  C. DNS
  D. Ipv4
  A. DHCP

  ---

  Explanation

  DHCP stands for Dynamic Host Configuration Protocol, which is a protocol that provides quick, automatic, and central management for the distribution of IP addresses within a network1. A DHCP server can assign IP addresses and other network information to devices that request them, such as computers, smartphones, and routers2. The IP address 169.254.2.2 is an example of an APIPA (Automatic Private IP Addressing) address, which is a special type of IP address that devices use when they cannot obtain a valid IP address from a DHCP server3. APIPA addresses are in the range of 169.254.0.1 to 169.254.255.254, with a subnet mask of 255.255.0.03. Devices that use APIPA addresses can only communicate with other devices on the same local network that also use APIPA addresses3. The router in the question is assigned the address scope of 192.168.1.254/24, which means it has an IP address of 192.168.1.254 and a subnet mask of 255.255.255.04. This address scope belongs to the private IP address range of 192.168.0.0 to 192.168.255.255, which is commonly used for local networks4. Devices that use private IP addresses can communicate with other devices on the same local network or across different networks through NAT (Network Address Translation)4. The most likely cause of the technician receiving the IP address 169.254.2.2 is that the DHCP server on the router is not working properly or is not configured correctly3. This could be due to various reasons, such as a misconfigured router, a faulty cable, a firewall blocking DHCP traffic, or an exhausted pool of IP addresses3. As a result, the technician's device cannot obtain a valid IP address from the DHCP server and resorts to using an APIPA address instead3. To fix this issue, the technician should check the router settings and make sure that the DHCP server is enabled and has enough available IP addresses to assign to devices2. The technician should also check the physical cabling and make sure it is properly connected and secured2. If the issue persists, the technician should try rebooting the router or resetting it to factory defaults2. Alternatively, the technician could manually assign a static IP address to the device that matches the router's address scope, such as 192.168.1.x/242.
