ECC Answer: D Explanation: When installing RAM into a server that will be used as a VM host, it is recommended to install ECC (Error-Correcting Code) RAM to help prevent errors that can cause virtual machines to crash.
When installing RAM into a server that will be used as a VM host, it is recommended to install ECC (Error- Correcting Code) RAM to help prevent errors that can cause virtual machines to crash. References: https://www.servermonkey.com/blog/ecc-vs-non-ecc-ram-what-are-the-differences.html
When installing RAM into a rackmount server that will be used as a VM host, it would be best to install ECC (Error Correcting Code) RAM which can detect and correct common types of data corruption.
ECC (Error-Correcting Code) RAM is specifically designed for servers and other critical applications where data integrity and system stability are paramount. It can detect and correct the most common kinds of internal data corruption. This makes it ideal for use in a VM host server where reliability and uptime are crucial.
ECC Answer: D Explanation: When installing RAM into a server that will be used as a VM host, it is recommended to install ECC (Error-Correcting Code) RAM to help prevent errors that can cause virtual machines to crash.
DDR4 (C): DDR4 is the fourth generation of Double Data Rate (DDR) memory and is commonly used as system memory in servers and high-performance computing environments. It provides improved performance and energy efficiency compared to previous generations like DDR3.
The answer is D. ECC.
ECC (Error Correcting Code) memory is a type of RAM that can detect and correct errors in data transmission. This makes it ideal for use in servers that host virtual machines, as virtual machines are more susceptible to errors than traditional applications.
DDR4 is the current standard for system memory in servers and offers improved performance and efficiency compared to previous generations. It is the recommended choice for server applications.
Whether ECC memory is necessary depends on the specific requirements and level of reliability needed for the VM host server, but the question doesn't specify anything about high reliability.
ECC is the spec for a server: from Crucial.com "ECC is a method of detecting and then correcting single-bit memory errors. A single-bit memory error is a data error in server output or production, and the presence of errors can have a big impact on server performance. There are two types of single-bit memory errors: hard errors and soft errors."
Therefore D.
This was actually on my exam and I didn't miss anything in this objective, so the correct answer is definitely ECC
