Q54. Which security mechanism ensures secure access to internal assets while enabling Internet-based access to selected resources?

 Virtual local area network

 Demilitarized zone

 Virtual private network

 Discovery domain

Demilitarized Zone A control to secure internal assets while enabling Internet-based access to selected resources.

Q55. Which compute system component enables dynamic extension of file system capacity and efficient storage management?

 Logical Unit Number

 Logical Unit Number Masking

 Logical Volume Manager

 Virtual Memory Manager

Explanation
The evolution of LVMs enabled dynamic extension of file system capacity and efficient storage management.
The LVM provides optimized storage access and simplifies storage resource management. It hides details about the physical disk and the location of data on the disk. It enables administrators to change the storage allocation even when the application is running.

Q56. A company plans to deploy a new application in their environment. The new application requires 2 TB of storage space. During peak workloads, the application is expected to generate 4500 IOPS with a typical I/O size of 4 KB. The capacity of each available disk drive is 250 GB. In addition, the maximum number of IOPS a drive can perform at with a 70% utilization is 90 IOPS.
What is the minimum number of disk drives needed to meet the application’s capacity and performance requirements for a RAID 0 configuration?
