NEW QUESTION # 355
A systems administrator is selecting the appropriate RAID level to support a private cloud with the following requirements:
. The storage array must withstand the failure of up to two drives.
. The storage array must maximize the storage capacity of its drives.
Which of the following RAID levels should the administrator implement?
Answer: A
Explanation:
RAID stands for Redundant Array of Independent Disks, which is a technology that combines multiple physical disks into a logical unit that provides improved performance, reliability, and storage capacity. RAID levels are different ways of organizing and distributing data across the disks in a RAID array. Each RAID level has its own advantages and disadvantages, depending on the requirements and trade-offs of the system.
RAID 6 is a RAID level that uses block-level striping with double parity. This means that data is divided into blocks and distributed across all the disks in the array, and two sets of parity information are calculated and stored on different disks. Parity is a method of error detection and correction that can reconstruct the data in case of disk failure. RAID 6 can withstand the failure of up to two disks without losing any data, which makes it suitable for a private cloud that requires high fault tolerance. RAID 6 also maximizes the storage capacity of its drives, as it only uses two disks for parity and the rest for data. The storage capacity of a RAID 6 array is equal to (n-2) x S, where n is the number of disks and S is the size of the smallest disk.
RAID 0, RAID 1, RAID 5, and RAID 10 are other RAID levels, but they do not meet the requirements of the private cloud. RAID 0 uses striping without parity, which improves performance but does not provide any redundancy or fault tolerance. RAID 0 cannot withstand any disk failure, as it would result in data loss. RAID
1 uses mirroring, which copies the same data to two or more disks. RAID 1 provides high reliability and fast read performance, but it wastes half of the storage capacity for redundancy. RAID 1 can only withstand the failure of one disk in each mirrored pair. RAID 5 uses striping with single parity, which distributes data and parity across all the disks in the array. RAID 5 provides a balance of performance, reliability, and storage capacity, but it can only withstand the failure of one disk. RAID 10 is a combination of RAID 1 and RAID 0, which creates a striped array of mirrored pairs. RAID 10 provides high performance and reliability, but it also wastes half of the storage capacity for redundancy. RAID 10 can withstand the failure of one disk in each mirrored pair, but not more than that.

NEW QUESTION # 356
A physical server with SSD drives that hosts an IO-intensive database has been migrated into a private cloud to ensure further growth possibilities and accommodate quarterly load spikes (up to
10,000 IOPs). The requirement is to have log partition latency below 5ms and data partition latency below 10ms, irrespective of the load spikes. A cloud administrator has conducted extensive tests after the migration. Which of the following test results would ensure the migration is successful?
Answer: B
NEW QUESTION # 357
An organization is implementing a new requirement to facilitate faster downloads for users of corporate application content. At the same time, the organization is also expanding cloud regions. Which of the following would be suitable to optimize the network for this requirement?
Answer: A
Explanation:
CDN, or content delivery network, is a system of distributed servers that deliver web content to users based on their geographic location, the origin of the web page, and the content delivery server1. A CDN can improve the performance, availability, and scalability of cloud applications by caching static and dynamic content at the edge of the network, reducing the latency and bandwidth consumption between the users and the cloud servers2. A CDN can also provide security features such as encryption, authentication, and DDoS protection3.
Autoscaling, SR-IOV, and containerization are other techniques that can optimize the network for cloud applications, but they are not directly related to the requirement of faster downloads for users. Autoscaling is the process of automatically adjusting the number and size of compute resources based on the demand and workload of the application. SR-IOV, or single root I/O virtualization, is a technology that allows a physical network device to be partitioned into multiple virtual devices that can be assigned to different virtual machines or containers, bypassing the hypervisor and improving the network performance and efficiency.
Containerization is the process of packaging an application and its dependencies into a lightweight and portable unit that can run on any platform, providing isolation, consistency, and portability.

NEW QUESTION # 359
An OS administrator is reporting slow storage throughput on a few VMs in a private IaaS cloud.
Performance graphs on the host show no increase in CPU or memory. However, performance graphs on the storage show a decrease of throughput in both IOPS and MBps but not much increase in latency. There is no increase in workload, and latency is stable on the NFS storage arrays that are used by those VMs.
Which of the following should be verified NEXT?
Answer: D
