RDS accounts can be used to connect with the databases created on a given RDS instance. Each account can be bound with multiple databases. Yet, the read/write permissions of each database can only be assigned to one RDS account

  1. True
  2. False

Answer(s): B

Explanation:

RDS accounts can be used to connect with the databases created on a given RDS instance. Each account can be bound with multiple databases. However, the read/write permissions of each database can be assigned to multiple RDS accounts, not just one. For example, you can create an account with read-only permission for all databases, and another account with read-write permission for a specific database. This way, you can manage the access control of your databases more flexibly and securely.

Object Storage Service (OSS) supports sub accounts, and you can allocate access permissions to different buckets for each sub account.

  1. True
  2. False

Answer(s): A

Explanation:

Object Storage Service (OSS) supports sub accounts, which are the accounts that belong to a parent account and share the resources of the parent account. You can allocate access permissions to different buckets for each sub account by using bucket policies or RAM policies. Bucket policies are the access control policies that are attached to buckets and specify the permissions that other users have on the resources in the buckets. RAM policies are the access control policies that are attached to RAM users or RAM user groups and specify the permissions that the RAM users or RAM user groups have on the OSS resources.

When a customer uses Alibaba Cloud Object Storage Service (OSS) service and finds there exist an amount of Internet downstream traffic, he/she can use Alibaba Cloud Content Delivery Network (CDN) service to reduce the traffic cost.

Because the Internet traffic cost of CDN is lower than that of OSS, moreover, the back-to-source traffic cost from CDN to OSS is also lower than a user access to OSS directly.

  1. True
  2. False

Answer(s): A

Explanation:

Alibaba Cloud Content Delivery Network (CDN) is a distributed network that delivers content to users based on their geographic locations. CDN can reduce the latency and improve the user experience of accessing content from the Internet. CDN can also reduce the Internet downstream traffic of OSS by caching the content in the edge nodes of CDN. The Internet traffic cost of CDN is lower than that of OSS, and the back-to-source traffic cost from CDN to OSS is also lower than a user access to OSS directly. Therefore, using CDN can reduce the traffic cost of OSS.

Alibaba Cloud Elastic Compute Service (ECS) instances in different Security Groups will definitely have no way to communicate with each other.

  1. True
  2. False

Answer(s): B

Explanation:

Alibaba Cloud Elastic Compute Service (ECS) instances in different security groups are isolated from each other by default, but they can communicate with each other if the security group rules allow it. A security group is a virtual firewall that controls the inbound and outbound traffic of ECS instances. You can configure security group rules to specify which IP addresses, protocols, and ports can access the ECS instances in a security group. You can also authorize other security groups to access the ECS instances in a security group, which enables cross-security group communication.
