CompTIA A+ certification is widely recognized as one of the most important certifications for entry-level IT professionals. It is a vendor-neutral certification, which means that it is not specific to any particular hardware or software vendor. This makes it a valuable certification for anyone looking to work in the IT industry, regardless of which vendor they work with.

NEW QUESTION # 211
A technician plans to upgrade a laptop's RAM from 4GB to 16GB. Which of the following should the technician do?

A. Purchase the same brand of RAM.
B. Configure the laptop's BIOS settings for the RAM upgrade.
C. Purchase the same architecture of RAM.
D. Purchase RAM with the same CAS latency.

Answer: C

Explanation:
The most important factor to consider when upgrading a laptop's RAM is the architecture of the RAM, which determines the type, speed, and capacity of the memory modules. The architecture of the RAM must match the architecture of the laptop's motherboard and processor, otherwise the RAM will not be compatible or function properly. The architecture of the RAM includes the DDR generation (such as DDR3 or DDR4), the form factor (such as SO-DIMM), the pin count (such as 204 or 260), the voltage (such as 1.35V or 1.5V), and the frequency (such as 1600MHz or 2400MHz).
The other options are not as crucial or relevant for the RAM upgrade. The brand of the RAM does not matter as long as the RAM meets the specifications of the laptop and is of good quality. The CAS latency of the RAM is a measure of the delay between the memory controller requesting data and the RAM delivering it, and it affects the performance of the RAM. However, the CAS latency is not a fixed value and can vary depending on the frequency and voltage of the RAM. Therefore, purchasing RAM with the same CAS latency is not necessary or sufficient for compatibility. The laptop's BIOS settings are usually configured to automatically detect and adjust to the RAM upgrade, and do not need to be manually changed by the technician.

https://intellinetnetwork.eu/pages/what-is-a-poe-injector
The quickest way to resolve the issue is to install a Power over Ethernet (PoE) injector to provide power to the IP phone. An unmanaged switch does not provide PoE, so an injector is needed to power the phone.

An insurance company wants to implement cloud computing and would like a cloud solution in which the infrastructure is shared with businesses in the same industry. Which of the following cloud models BEST addresses the company's need?

A. Community
B. Hybrid
C. Private
D. Public

Answer: B

Explanation:
In a hybrid cloud model, the infrastructure is shared between public cloud services and an on-premise private cloud. This means that the insurance company can benefit from the scalability and cost-effectiveness of public cloud services, while also having the control and security of a private cloud. This allows the company to access resources that are specialized to their industry, while also ensuring that their data and infrastructure are kept secure.
