A systems administrator is planning to migrate to a cloud solution with volume-based licensing. Which of the following is most important when considering licensing costs?
Correct Answer: C
Volume-based licensing is a model where the cost of the software is based on the number of licenses purchased1. This model is commonly used for software that is installed on a specific number of devices, such as antivirus software or office productivity suites1. Therefore, the number of machines is the most important factor when considering licensing costs in this model.
Question 82
A cloud administrator is securing access to a VM using an IaaS cloud platform. The administrator must perform this task using an automated method, allow administrators to perform any method and expose any property of the VM, deny access for everyone else, and allow only read-only access to everyone else. Given this scenario, which of the following should the administrator use to BEST meet these requirements?
Correct Answer: A
Question 83
An administrator needs to back up all the data from each VM daily while also saving space. Which of the following backup types will BEST fit this scenario?
Correct Answer: B
Question 84
A systems administrator wants the VMs on the hypervisor to share CPU resources on the same core when feasible. Which of the following will BEST achieve this goal?
Correct Answer: D
Question 85
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?
Correct Answer: D
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 dat a. 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.
