• Question 1002:

  Which of the following best describes the concept of a DHCP lease?

  A. A definition of the scope of addresses to be assigned to a device on the network
  B. A reservation of an IP configuration for a device on the network
  C. A temporary assignment of an IP configuration to a device on the network
  D. A translation of network names to IP addresses for a device on the network
  C. A temporary assignment of an IP configuration to a device on the network

  ---

  Explanation

  A DHCP lease is a temporary assignment of an IP address and other network configuration parameters (such as DNS and gateway) to a device. The lease is renewed periodically to maintain the assignment.

  Why Not A (A definition of the scope of addresses): The DHCP scope defines the range of IP addresses but is not the lease itself.

  Why Not B (A reservation of an IP configuration): DHCP reservations ensure a specific device always receives the same IP address, but this is not the lease.

  Why Not D (A translation of network names to IP addresses): This describes DNS, not DHCP.

• Question 1003:

  A technician powers on a PC and its monitor and sees the following error message:

  No input signal detected

  The display lights on the computer are on. Which of the following is a possible solution?

  A. Changing the BIOS settings
  B. Changing the connector setting on the monitor
  C. Checking the power plug on the monitor
  D. Checking the power plug on the PC
  B. Changing the connector setting on the monitor

  ---

  Explanation

  Changing the connector setting on the monitor is a possible solution for a PC and its monitor that display the error message "No input signal detected". This error can be caused by an incorrect input selected on the monitor, so changing the connector setting to the correct input should resolve the issue.

• Question 1004:

  Which of the following devices is capable of dynamically distributing an IP address?

  A. Hub
  B. Switch
  C. Injector
  D. Router
  D. Router

  ---

  Explanation

  A router is a device that connects multiple networks and forwards packets between them based on their destination IP addresses. A router can also perform DHCP (Dynamic Host Configuration Protocol) function, which means it can dynamically distribute IP addresses to devices on its network. A router can also provide other features, such as firewall, NAT (Network Address Translation), VPN (Virtual Private Network), and QoS (Quality of Service).

• Question 1005:

  A technician installs a new printer for a workstation and tries to print a test page, but the page does not print. The technician looks at the print queue and notices that the printer is called 'Generic Printer." Which of the following BEST describes what the technician should do to fix this issue?

  A. Connect the printer with a USB cable rather than over the network.
  B. Install the appropriate printer drivers for the OS.
  C. Install the correct toner in the printer.
  D. Set the printer trays to allow duplex printing
  B. Install the appropriate printer drivers for the OS.

  ---

  Explanation

  The technician should install the appropriate printer drivers for the OS to enable the computer to communicate with the printer. The generic printer name suggests that the drivers are missing or not installed correctly.

• Question 1006:

  A technician receives a cellular from a manager. The technician is instructed to download a service manual directly from the Internet to a laptop. However, there is no WiFi signal or wired Ethernet. Which of the following would be the MOST appropriate connections for the technician to use?

  A. Hotspot
  B. NFC
  C. Bluetooth
  D. VPN
  A. Hotspot

  Explanation

• Question 1007:

  A user reports that a laptop's display is too dim.

  Which of the following should a technician try first to troubleshoot the issue?

  A. Check the refresh rate of the laptop display and adjust it if necessary.
  B. Make sure the correct cables are being used for the connection.
  C. Check the settings of the laptop display.
  D. Make sure the video card driver is updated.
  E. Check the resolution of the laptop display.
  C. Check the settings of the laptop display.

  ---

  Explanation

  The first step to troubleshoot a dim laptop display is to check the settings of the laptop display, such as the brightness level, the power plan, and the adaptive brightness feature. These settings can affect the brightness of the screen and may be automatically adjusted by Windows or the user. If the settings are not optimal for the user's preference or environment, the screen may appear too dim even at full brightness. Therefore, the technician should check and modify these settings before trying other solutions.

• Question 1008:

  A customer is having an issue printing documents. The customer can print a text document without any issue. However, when the customer prints a PDF containing images, the job fails and no other jobs will run until the computer is rebooted.

  Which of the following is the most likely cause of the issue?

  A. The firmware is EOL.
  B. The printer is using a PostScript driver.
  C. The user is sending too many documents.
  D. The print queue is moving too slowly.
  B. The printer is using a PostScript driver.

  ---

  Explanation

  Printers that use PostScript drivers are designed to handle complex printing tasks, including detailed graphics and images in PDF files. However, if the printer's PostScript driver is outdated, incompatible, or improperly configured, it may struggle to process and print PDF files containing images. Updating or reinstalling the PostScript driver, or choosing a different driver compatible with the printer and document type, can resolve this issue.

• Question 1009:

  A user's wireless headset shows a "connected" status when turned on, but the Bluetooth list on the user's phone shows that the headset is "not connected." Which of the following should the technician do?

  A. Enter the PIN.
  B. Turn off Wi-Fi.
  C. Re-pair the devices.
  D. Enable Bluetooth.
  C. Re-pair the devices.

• Question 1010:

  A cloud engineer, who is designing a cloud architecture, needs to ensure the solution is able to immediately fail over to another region in case of an outage and also scale up in the event of high utilization. Which of the following should the engineer Implement? (Select two).

  A. High availability
  B. Elasticity
  C. Cold storage
  D. Machine learning
  E. Metered utilization
  F. Virtualization
  A. High availability
  B. Elasticity

  ---

  Explanation

  The answer is A. High availability and

  B. Elasticity.

  High availability is the ability of a system to remain operational and accessible with minimal or no downtime, even in the event of failures, disasters, or disruptions. High availability can be achieved by designing a system that has redundancy, fault tolerance, and disaster recovery capabilities. For example, a cloud engineer can design a system that replicates data and resources across multiple regions, zones, or availability domains, and uses load balancing and failover mechanisms to distribute the workload and handle failures gracefully12. Elasticity is the ability of a system to scale up or down automatically in response to changes in demand or utilization. Elasticity can be achieved by designing a system that can dynamically allocate and deallocate resources based on predefined metrics, policies, or triggers. For example, a cloud engineer can design a system that uses auto-scaling groups, horizontal or vertical scaling strategies, and on-demand or spot instances to optimize the performance and cost of the system32. By implementing high availability and elasticity, a cloud engineer can ensure that the solution is able to immediately fail over to another region in case of an outage and also scale up in the event of high utilization. These are two important aspects of building reliable and scalable cloud architectures. Therefore, options A and B are the correct answers.
