Exam CV0-003 topic 1 question 293 discussion

Explanation: When deploying domain controllers in a public cloud environment with 500,000 users and objects, the lowest cost per I/O is crucial. A hybrid storage solution combines HDDs (for cost efficiency) and SSDs (for improved read/write performance), making it the best choice for balancing cost and performance. 🔹 Why Hybrid Storage? ✅ Cost-Effective: More affordable than full SSD/Flash solutions. ✅ Performance Boost: Uses SSD caching to speed up frequently accessed data. ✅ Balanced IOPS: Suitable for directory services, which involve frequent reads but don’t require extreme speeds.

Correct is A, While maintaining a reasonable price point and factoring in I/O you would want a hybrid environment that incorporate SSD's and HDD's.

The correct answer is B and NOT D. SAS (Serial Attached SCSI) storage is a type of data storage technology used primarily in enterprise environments. It connects hard drives and solid-state drives (SSDs) to a computer or server using a point-to-point serial protocol, offering several advantages: Here are three benefits of using SAS storage over SSD 1. Cost-Effectiveness: SAS drives generally offer a lower cost per gigabyte compared to high-capacity SSDs, making them more economical for large-scale storage needs, especially in environments where high capacity is required over speed. 2. Reliability: SAS drives are designed for 24/7 operation and include advanced error recovery features, making them highly reliable for critical enterprise applications that require consistent uptime and data integrity. Yes, SSD has the highest I/O but is cost-intensive which makes it not the best option for this scenario.

D is da way

SSD has the highest I/O by far and therefore the lowest cost per I/O.

For a scenario where you need to deploy domain controllers to authenticate a large number of users and computer objects with a focus on achieving the lowest cost per I/O, "SAS" (Serial Attached SCSI) storage would be a reasonable choice. SAS drives provide a good balance between performance and cost. They are often less expensive than Flash (solid-state drives or SSDs) but offer better I/O performance compared to traditional HDDs (hard disk drives). In environments where read and write performance is important but you want to control costs, SAS drives are commonly used. So, the answer is: B. SAS

I'm going with Hybrid. Answer A. Because, the purpose behind hybrid disks which use a mix of SSD and HDD technologies is to maximize performance and cost. Frequently accessed data is stored on the flash memory and less commonly used information is stored on the spinning disks.

It could be D as SSD typically provides the best performance at the lowest cost per I/O is and offer low latency and high I/O operations per second (IOPS), which are crucial for domain controllers that need to handle a large number of authentication requests.
