A technician installed a new router at a small office. After the Installation, the technician notices that all devices have a I69.254.x.x IP address. Printers and fileshares are still working, but PCs cannot access the Internet. Which of the following should the technician configure on the router to enable devices to connect to the internet?
To enable devices to connect to the internet after installing a new router at a small office, the technician shouldconfigure DHCP (Dynamic Host Configuration Protocol)on the router. DHCP is a network protocol that automatically assigns IP addresses and other network configuration parameters to devices on a network. By configuring DHCP on the router, the technician can ensure that all devices on the network are assigned a valid IP address that allows them to connect to the internet.
If all devices have a 169.254.x.x IP address, this suggests that the router is not assigning IP addresses to the devices using DHCP (Dynamic Host Configuration Protocol). Configuring the DHCP settings on the router can enable the devices to receive IP addresses automatically and access the internet.

A company gives users microSD cards to install on smartphones so users can store pictures that will be used on the website. After installing the cards, users report only being able to save a small number of pictures on the microSD cards before running out of space. Which of the following is the most likely issue?
If users are only able to save a small number of pictures on the microSD cards before running out of space, it suggests a formatting issue. Improper or incomplete formatting can lead to the card not utilizing its full storage capacity, resulting in significantly less available space for storing pictures. Formatting the microSD cards correctly would ensure the file system on the cards is set up properly, allowing the devices to use the full capacity of the cards for storage. Compatibility, UHD storage capability, and camera storage settings are less likely to be the issue in this scenario.
In which of the following cloud models is the customer not responsible for hardware and OS layers but is responsible for the data and the application?
In Platform as a Service (PaaS), the cloud provider manages the hardware, operating system, and middleware, while the customer is responsible for managing data and applications.
Why Not B (SaaS): In SaaS, the provider manages all layers, including applications and data, leaving no responsibility for the customer.
Why Not C (IaaS): In IaaS, the customer manages the OS, data, and applications, while the provider only handles the hardware.
Why Not D (CaaS): CaaS (Container as a Service) is not a primary cloud model described in the CompTIA objectives and is less commonly referenced.
CompTIA A+ Exam Reference: Core 1 (220-1101), Section 4.1, cloud computing models.
A user has decided to build a new computer with parts purchased from a popular online vendor The user has referenced online resources to assemble the unit. However, when the user presses the power button, the new computer does not load the operating system's installer. Instead, the onboard speaker beeps and immediately reports an issue on the screen. Which of the following is the MOST likely issue with the new build?
If a computer is not booting and the onboard speaker emits beeps, it can indicate a hardware issue. One of the most common causes of beep codes is overheating, which can occur if the processor's fan is not properly installed and running. The processor's fan is responsible for cooling the processor and preventing damage to the internal components.
A user experiences a random BSOD while using a computer, but the operating system recovers as expected Which of the following symptoms would indicate the issue is related to RAM?
