VMware, ESXi, Microsoft Hyper-v, and open-source KVM are some examples of which Type of hypervisor?

  1. 2
  2. 3
  3. 4
  4. 1

Answer(s): D

Explanation:

Correct Answer:
1 Hypervisor is a small software layer that enables multiple operating systems to run alongside each other. Hypervisor separates the VMs logically, assigning each its own slice of underlying computing power, memory, and storage. There are 2 types of Hypervisor:
Type 1 & Type 2. Type 1 Hypervisors:
Can support multiple virtual machines Also known as a "bare metal" hypervisors Most frequently used and seen in the market, most secure, lower latency Examples include VMware ESXi, Microsoft Hyper-V, open source Kernel-based Virtual Machine



Which cloud storage have poor performance when data needs to be shared?

  1. Direct Attached
  2. Block Storage
  3. File Storage
  4. Object Storage

Answer(s): A

Explanation:

Direct area storage, also known as direct-attached storage (DAS), is as the name implies. DAS is a storage device which directly connected to your computer or server, if often connected to a single machine only. Some examples of direct attached storage are floppy disks, optical disc, compact discs (CDs) and digital video discs (DVDs), hard disk drives (HDD), flash drives and solid-state drives (SSD). DAS is often connected with single computing machine only so sharing capabilities are limited and poor. Block storage is highly available and resilient and will often include data encryption at rest and in transit. Block storage, is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. It can be attached to compute instance. Block Storage normally mounted onto only one compute node at a time. With block storage, you specify the size of the storage and pay a fee based on the size you provisioned. Block storage suitable for low latency workloads where consistently high speeds required. File Storage associated with Network Attached Storage (NAS) technology. File Storage organizes files in a hierarchy of named directories.
The ability for File Storage to be mounted to multiple compute nodes at a time make it an ideal solution for common storage requirements. Object Storage enable you to store and access unstructured data anywhere in the world with a self-service portal backed by RESTful APIs. Object Storage supports exponential data growth and cloud-native workloads with built-in high-speed file transfer capabilities, cross-region offerings and integrated services. Use cases:
Backup and recovery, Data archiving, Cloud-native application, AI and big data analytics.



Select the answer that correctly completes the sentence. ____ is the process of taking existing legacy applications and modernizing their platform infrastructure, internal architecture, and/or feature.

  1. Application modernization
  2. Virtualization
  3. Isolation
  4. Containerization

Answer(s): A

Explanation:

Application modernization:
Application modernization is the process of taking existing legacy applications and modernizing their platform infrastructure, internal architecture, and/or feature. Application modernization is the process of migrating traditional applications to run in modern cloud environments.



When referring to cloud computing, what does the term cloud mean?

  1. It is a metaphor for the internet based on the basic cloud drawing used to represent the telephone network.
  2. It refers to the virtual hardware that cloud computing is built on.
  3. It is the name of an operating system that is very flexible and easy to use so anyone can design, build, and provide cloud services, such as Infrastructure as a Service, Platform as a Service, and Software as a Service
  4. It is a metaphor for a data storage service with an ever-growing capacity, like storm clouds.

Answer(s): A

Explanation:

Cloud is a metaphor for the internet based on the basic cloud drawing used to represent the telephone network.
[Exam Tips]:
On-demand self-service is an essential characteristic of cloud computing.
