  Rapid elasticity is only suitable for a domain whose resource requirements suddenly up and down for a specific time interval. Referring to the question the online retailer wants to migrate to public cloud services during peak season, then wants it to be removed "automatically" when the peak is over.

• Question 702:

  A mechanical engineer's PC has started randomly shutting off whenever the engineer attempts to render a design. The mechanical engineer states that the PC has worked for three years without issue.

  Which of the following should the technician perform first to diagnose the issue? (Select two).

  A. Listen for POST beeps when turning on the PC.
  B. Check if the computer is overheating.
  C. Run chkdsk.
  D. Reinstall the operating system.
  E. Check if the graphics card is compatible with the motherboard.
  F. Replace the HDD.
  A. Listen for POST beeps when turning on the PC.
  B. Check if the computer is overheating.

  ---

  Explanation

  The mechanical engineer's PC shutting off during resource-intensive tasks like rendering could be caused by overheating or hardware issues. The two most logical steps to diagnose the problem are:

  Check if the computer is overheating: Rendering is a CPU- and GPU-intensive task that generates significant heat. Overheating could cause the system to shut down as a protective measure. Checking the system's temperature can help identify if this is the cause.

  Listen for POST beeps when turning on the PC: POST (Power-On Self-Test) beeps can indicate hardware issues, such as problems with the motherboard, CPU, or GPU. Listening for beeps can help identify potential faults in these components.

  Why the other options are incorrect:

  Run chkdsk: This tool is used for checking disk integrity, but the symptoms don't suggest a hard drive issue.

  Reinstall the operating system: Reinstalling the OS is time-consuming and not typically necessary for hardware-related shutdowns. Check if the graphics card is compatible with the motherboard: If the PC has been working for three years, the GPU is already compatible with the motherboard. Replace the HDD: There's no indication that the hard drive is causing the issue, as the problem occurs during rendering, which is more GPU/CPU-intensive.

  This topic falls under the Hardware Troubleshooting domain in the CompTIA A+ Core 1 exam.

• Question 703:

• Question 705:

  An engineer is upgrading the power supply of a workstation to add a GPU. The current power supply is 380W, and the GPU is a six-pin power connector.

  Which of the following is the minimum power supply the engineer should install?

  A. 400W
  B. 450W
  C. 500W
  D. 550W
  B. 450W

  ---

  Explanation

  Upgrading a power supply to add a GPU typically requires more wattage to accommodate the additional power demands. Although the current power supply is 380W, adding a GPU with a six-pin power connector suggests a mid-range graphics card, which would likely need a total system power supply in the range of 450W to ensure adequate power for all components, providing a good balance between capacity and safety margins.

• Question 706:

  A user's phone does not respond to touch. A technician inspects the phone but does not see any evidence of physical damage. The technician restarts the device, which does not fix the issue.

  Which of the following components should the technician examine next?

  A. Battery
  B. Screen
  C. Stylus
  D. Digitizer
  D. Digitizer

  ---

  Explanation

  The digitizer is responsible for detecting touch input, so if the phone is not responding to touch, it is likely the digitizer is malfunctioning.

• Question 707:

  A user reports that printed receipts have black smudges over the entire image. The text is still present but is very dark and sometimes illegible. Which of the following are the MOST likely cause and solution for the printer issue?

  A. The ribbon is jammed and is rubbing on the paper. Clear the bad ribbon and feed it through properly.
  B. The printhead is too hot. Adjust the temperature down and retry printing.
  C. The printer is loaded with the wrong type of paper. Replace the receipt paper with carbon paper.
  D. The blue ink cartridge was loaded with black ink. Put in the correct ink and clean the printhead.
  B. The printhead is too hot. Adjust the temperature down and retry printing.

  ---

  Explanation

  Receipts are printed via a thermal printer. Thermal printers work by heating a paper in specified areas in order to create an image. The specific component that does this is a thermal printhead. Since the image appears to have black smudges and is too dark, we know the thermal printhead is too hot since the capability of precise heating has diminished

• Question 708:

  A technician configured a new SOHO router for a small business. The ISP gave the technician an IP address on the router's WAN port. Which of the following addresses did the technician most likely configure on the router?

  A. 10.1.50.30
  B. 19.45.7.28
  C. 169.254.168.10
  D. 172.22.40.6
  B. 19.45.7.28

  ---

  Explanation

  This is an example of a public IP address that can be assigned by an ISP to a router's WAN (Wide Area Network) port. A public IP address is a globally unique and routable address that allows a device to communicate with other devices on the internet. A private IP address, such as 10.1.50.30 or 172.22.40.6, is a non-routable address that is used within a local network and cannot be directly accessed from the internet. A link-local IP address, such as 169.254.168.10, is a self-assigned address that is used when a device cannot obtain a valid IP address from a DHCP server.

• Question 709:

  An employee is on a business trip and needs to upload daily conferences and meetings to the company's intranet. The uploading process is successful but was faster in the past.

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

  A. Wireless is turned off.
  B. 5G is disabled.
  C. Roaming is turned on.
  D. Data is being throttled.
  D. Data is being throttled.

  ---

  Explanation

  Data throttling, often implemented by network providers to manage bandwidth usage, can slow data speeds after a certain usage limit is reached. Turning off wireless would prevent uploads, while roaming and 5G status primarily affect connectivity rather than speed throttling. CompTIA A+ Core 1 objectives cover connectivity troubleshooting for mobile devices, including factors impacting network speed and performance.

• Question 710:

  A new directive mandates the use of a security component to securely allow users to authenticate to systems, access sensitive data, and enter the office. The component must provide an additional factor of authentication alongside user accounts and cannot be something the user owns.

  Which of the following components best meets these requirements?

  A. Fingerprint reader
  B. Smart card
  C. Secure token
  D. NFC scanner
  B. Smart card

  ---

  Explanation

  A smart card provides an additional factor of authentication by storing secure credentials, such as certificates, that cannot be guessed or replicated. It complements user accounts and is "something you have".

  Why Not A (Fingerprint reader): This is "something you are", but the scenario specifically requires a physical token.

  Why Not C (Secure token): Secure tokens are also valid but may not integrate as seamlessly into multi-factor authentication for physical and system access.

  Why Not D (NFC scanner): An NFC scanner is a device and not a token itself; it reads cards or other credentials.
