Data shredding is a method of data destruction that goes beyond simple deletion. It involves overwriting the data on a storage device multiple times with random data to ensure that the original data cannot be recovered. This process is used to securely erase sensitive information and protect against data breaches and unauthorized access.References: Dell Information Storage and Management V5 documents, ExamTopics.
Question 2
What is a feature a hypervisor?
Options:
A.
Provides a VMM that manages all VMS on a clustered compute system
B.
Isolates the VMS on a single compute system
C.
Provides a VMM that manages all VMS on a single compute system
D.
Isolates the physical resources of a single compute system
Answer:
C
Explanation:
Explanation:
A hypervisor is a layer of software that runs directly on top of a physical server and provides a virtualization layer. It allows multiple virtual machines (VMs) to run on the same physical hardware, sharing the underlying resources such as CPU, memory, and storage. The hypervisor isolates the VMs from each other and provides a virtual machine monitor (VMM) that manages the virtual machines' access to physical resources. The VMM is responsible for managing the VMs' creation, configuration, and removal, as well as their access to the physical resources of the host system. T
Question 3
Which type of interface connects SSD drives to the storage array controller?
Options:
A.
NVMe
B.
NVMe/IB
C.
NVMe-oF
D.
NVMe/TCP
Answer:
A
Explanation:
Explanation:
an interface is a logical connection that enables data transfer between devices. There are different types of interfaces that can connect SSD drives to the storage array controller, such as SATA, SAS, PCIe, and NVMe.
One of the types of interface that can connect SSD drives to the storage array controller is NVMe1. NVMe stands for Non-Volatile Memory Express and it is a protocol that enables high-performance communication between SSDs and PCIe bus. NVMe reduces latency and increases throughput by using multiple parallel queues and direct memory access.
