Question 1 of 46

Using a cloud computing service is simple and straightforward. One can choose the instance with desired specification, finish payment and then use it right away.

Moreover, the underlying physical machines are managed by cloud service providers and transparent to users.

A.

TRUE

B.

FALSE

Correct Answer: A

Using a cloud computing service is generally simple and straightforward. Users can choose an instance with their desired specifications, complete the payment process, and start using the instance right away. Cloud service providers handle the underlying physical hardware, including server maintenance, infrastructure scaling, and hardware upgrades, making it transparent to users. This abstraction of the physical infrastructure is one of the key benefits of cloud computing, as users can focus on their applications and services without the need to manage the underlying hardware.

Question 2 of 46

A/An _________________ is a copy of data on a disk at a certain point in time.

A.

image

B.

snapshot

C.

template

D.

EIP

Correct Answer: B

A snapshot is a copy of data on a disk at a certain point in time. It captures the exact state of the data at that moment, making it useful for backups, data recovery, and creating copies for testing or development purposes. It differs from an image, which is generally a complete copy of an entire disk or system, as snapshots are typically incremental and focus on changes from a particular point in time.

Question 3 of 46

Multiple lower-configuration I/O-optimized ECS instances can be used with ___________ to deliver a high-availability architecture.

A.

Server Load Balancer

B.

RDS

C.

Auto Scaling

D.

OSS

Correct Answer: A

Multiple lower-configuration I/O-optimized ECS instances can be used with Server Load Balancer to deliver a high-availability architecture. The Server Load Balancer distributes incoming traffic across multiple ECS instances, ensuring high availability, fault tolerance, and scalability. This setup helps balance the load and provides redundancy, enhancing the overall availability of services.

Question 4 of 46

What is the full name of ECS?

A.

Elastic Compute Service

B.

Elastic Computing Server

C.

Elastic Cost Server

D.

Elastic Communication Server

Correct Answer: A

ECS stands for Elastic Compute Service. It is typically used in cloud computing to refer to virtual servers provided by cloud providers, such as Alibaba Cloud. This service allows for flexible computing capabilities.

Question 5 of 46

Alibaba Cloud does not support Intranet communication between products that are not in the same region, which does not mean ______________?

A.

ECS instances in different regions cannot communicate with each other on the intranet.

B.

ECS instances and other products in different regions, such as ApsaraDB for RDS and OSS instances, cannot communicate with each other on the intranet.

C.

Server Load Balancer cannot be deployed for ECS instances in various regions.

D.

Server Load Balancer can be deployed for ECS instances in various regions.

Correct Answer: D

Alibaba Cloud's restriction on intranet communication between products in different regions does not mean that the Server Load Balancer cannot be deployed for ECS instances in various regions. The load balancer can technically be configured to manage traffic across different regions, leveraging services like Cloud DNS to route the incoming requests appropriately.
