This article mainly explains "what are the common questions in Linux cloud computing interview". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn what are the common questions in Linux cloud computing interview.

* * 1. What are the requirements of the virtualization platform when implementing the cloud? * *

The requirements for a virtualized platform to implement the cloud include:

A) manage service level policies

B) Cloud operating system

C) Virtualization platforms help differentiate back-end and user-level concepts from each other.

* * 2. What necessary aspects should users consider before using the cloud computing platform? * *

A) Compliance

B) data loss

C) data storage

D) Business continuity

E) uptime

F) data integrity of cloud computing

* * 3. Can you list several open source cloud computing platform databases? * *

Open source cloud computing platform databases are as follows:

A) MongoDB

B) CouchDB

C) LucidDB

* * 4. What security regulations have been implemented to protect cloud data? * *

Security regulations implemented to protect data in the cloud include:

A) processing: controls the data that is processed correctly and completely in the application.

B) File: it manages and controls the data processed in any file.

C) output reconciliation: it controls the data that needs to be reconciled between input and output.

D) input validation: control input data.

E) Security and backup: it provides security and backup and also controls security disclosure logs

* * 5. Can you list the database names of several large cloud providers? * *

A) Googlebigtable

B) AmazonsimpleDB

C) Cloud-based SQL

* * 6. Can you explain the difference between cloud and traditional data center? * *

A) the cost of traditional data centres is high due to heating and hardware / software problems.

B) when demand increases, the cloud can expand resources. Most of the money is spent on data center maintenance, which is not the case with cloud computing.

7. What are the characteristics of cloud architecture that are different from traditional architectures?

Features that set the cloud architecture apart from traditional architectures include:

A) on demand, the cloud architecture meets the hardware requirements.

B) the cloud architecture can increase or decrease resources on demand.

C) the cloud architecture can manage and handle dynamic workloads without hindrance.

* * 8. Can you list the difference between elasticity and scalability in cloud computing? * *

Scalability is a feature of cloud computing; with scalability, the increased workload can be handled as long as the resource capacity is increased accordingly. As another feature of cloud computing, resilience emphasizes the concept of enabling and decommissioning huge resource capacity.

* * 9. Can you list the services provided by the WindowAzure operating system? * *

WindowAzure provides three core services, including:

A) Computing services

B) Storage services

C) Management services

10. What are the different parts of the cloud architecture that are necessary?

A) Cloud inbound

B) processor speed

C) Cloud storage services

D) Cloud provider services

E) Inter-cloud communication

* * 11. What are the different stages in the cloud architecture? * *

A) Startup phase

B) Monitoring phase

C) shutdown phase

D) cleanup phase

* 12. Can you list the basic features of cloud computing? * *

A) elasticity and scalability

B) self-service configuration and automatic de-configuration

C) standardized interface

D) usage mode of self-billing

13. What are the basic building blocks in the cloud architecture?

A) reference architecture

B) Technical architecture

C) deploy the operational architecture

* * 14. Can you describe how the cloud architecture provides automation and performance transparency? * *

To provide performance transparency and automation, the cloud architecture uses many tools. It can manage cloud architecture and monitoring reports. It can also share applications that use the cloud architecture. Automation is a key part of the cloud architecture and helps improve quality levels.

15. Can you explain the role of high-performance cloud in cloud computing?

High-performance clouds are useful for transferring the maximum amount of data immediately. Professionals engaged in high-performance computing research often use high-performance clouds.

* * 16. Can you explain hybrid cloud and community cloud? * *

Hybrid cloud: hybrid cloud includes multiple service providers. It combines the functions of both public and private clouds. When companies need both private and public clouds, they use hybrid clouds.

Community cloud: the cost of this model is quite high; community cloud is used when multiple business organizations share common goals and needs and are ready to share the benefits of cloud services.

* * 17. What are the optimization strategies in the cloud? * *

To overcome maintenance costs and optimize resources, the concept of three data centers in the cloud is used: to provide recovery and backup mechanisms to ensure that all data is safe and sound in the event of a disaster or system failure.

* * 18. What is Amazon SQS? * *

In order to connect between different connectors, Amazon SQS messages are used; it acts as a "contact" in different components of Amazon.

* * 19. How can punch be used in Amazon Web Services? * *

In order for the system to respond more efficiently to sudden increases in traffic or load, providers use buffers. Buffers can synchronize different components. The component always receives and processes requests in an unbalanced manner. The balance between different components is managed by buffers so that they work at the same speed, thus providing faster services.

* * 20. Can you describe the hypervisor and its types in cloud computing? * *

The hypervisor is a virtual machine monitoring tool that manages resources for virtual machines. There are two main types of hypervisors.

Type 1: guest virtual machines run directly on host hardware, such as Xen and VMWareESXI.

Type 2: the guest virtual machine runs on hardware through the host operating system, such as KVM and OracleVirtualBox.
