QUESTION 24
A Virtual Private Cloud (VPC) is an isolated network environment that is completely isolated from each other The following statements about VPC are correct_________. (Number of correct answers: 2)

Each VPC has an independent tunnel ID, and a tunnel ID corresponds to a virtualized network.

ECS instances in a VPC use security group firewalls for Layer 2 network access control.

Subnets can be divided like the traditional network environment. Different cloud servers within each subnet are connected by the same router and different subnets are interconnected by switches.

The internal networks of different VPCs are completely isolated and can be interconnected through IP addresses mapped to the outside.

QUESTION 25
Before data communication is setup, the security groups match the security group rules one by one to query whether to allow access requests Assume that the user has created two security group rules 1 and 2 The protocol type, port range, authorization type, and authorization object of the two security group rules are the same. The difference is that Rule 1 is a denial policy, rule 2 is an allowed policy, so the following statement is correct_______ (Number of correct answers 2)

If rule 1 and rule 2 have the same priority, the rule of the denial policy takes effect first, and the rule of the allowed policy does not take effect

If rule 1 and rule 2 have the same priority, the rule of the allowed policy takes effect first, and the rule that of the denial policy does not take effect.

If rule 1 and rule 2 have different priorities, the rule with a small priority number takes effect

If rule 1 and rule 2 have different priorities, the rule with a large priority number takes effect.

QUESTION 26

QUESTION 27
Which of the following statements is NOT correct, when comparing RDS with a self-built database?

RDS requires no O&M while self-built database require a dedicated DBA for maintenance, which results in high HR costs.

RDS provides automatic backup while self-built databases require you to prepare storage space for backup copies and regularly verify that these copies can be restored.

RDS features a high availability of 99 95% while self-built databases require you to implement data protection primary-standby replication, and RAID all by yourself.

Self-built database support quick deployment and elastic scaling.

True

False

QUESTION 36
OSS supports multi-part uploading for large files, namely dividing a large file into multiple parts and uploading them in order. This function is suitable for scenarios such as uploading large files or uploading files with poor connectivity.

QUESTION 37
Alibaba Cloud Content Delivery Network (CDN) performs content acceleration with the support of intelligent DNS resolution The following function_________is NOT included in intelligent DNS resolution.

A user request is directed to the server nearest to the customer based on location information of the pre-configured IP section.

The intelligent DNS resolution can parse the same domain name into different IP addresses based on the IP of different visitors.

The intelligent DNS resolution supports web page content caching. A user will receive data from the origin site at first-time access, and then will be reading data from cache in subsequent requests

If a user activates mirror sites in different IDCs, intelligent DNS resolution can achieve load balancing by guiding customers in different places to different mirror sites.

QUESTION 38
