Access by real users

Being under cyber attack.

ECS server failure

5. An enterprise has three different departments, each with its own HUAWEI CLOUD account. The HR department deployed a file sharing website to share the data of all on-the-job employees. The business department uploads the employee's attendance data to their VPC database. The finance department needs to access the HR department's attendance data to calculate the employee's salary.

Configure VPC peering connections in the finance department and HR department. At the same time, configure VPC peering connections in the business department and HR department.

Configure a VPC peering connection between the business department and the financial department.

Because the accounts of the three departments are different, the VPC peering connection cannot be configured to get through the data.

6. 201.31.6 was blocked by the subnet ACL due to the security of the network platform

7. A company has 2 VPCs in the same region of HUAWEI CLOUD. The network segment of the first VPC is 10. 10.0.0/16. One of the subnets is 10. 10. 1.0/24. The network segment of the two VFCs is 10.40.0.0/16. One of the subnets is 10.40.1.0/24. How does the company administrator need to configure the two subnets to communicate?

Create 2 EIPs and bind one to each ecs instance of the VP

Create an ECS instance in each subnet, and then bind the elastic IP to the two instances respectively. Then establish a VN connection between the two instances.

Create 2 VPN gateways. One for each VPC

Create a peer-to-peer connection between two VPCs.

8. When a user uses the HUAWEI CLOUD ELB service to distribute load to multiple ECS instances, which of the following methods can be used to obtain the real IP address of the requesting user? (Multiple choice)

Layer 4 services can be obtained by installing the TOA plug-in on the back-end server to obtain the visitor's real I

Layer 4 services can be obtained directly without additional configuration.

Layer 7 services can be obtained directly without additional configuration.

The 7th layer service can obtain the visitor's real IP through Http Header: X-Forwarded For.

9. The health check mechanism of HUAWEI CLOUD ELB can identify whether there are unavailable ECS instances in the back-end server group. If there are, these abnormal ECS instances will not be assigned tasks until these ECS instances return to normal. However, in some special application scenarios, the health check needs to be turned off. Which of the following descriptions about turning off the health check is correct?

The health check cannot be closed on the fourth and seventh floors.

The health check can be turned off for the seventh layer service, but the health check cannot be turned off for the fourth layer service.

Both the fourth and seventh floors can close the health check.

The health check can be turned off for the fourth layer service, but the health check cannot be turned off for the seventh layer service.

10. Which of the following statements about Pods in a HUAWEI CLOUD CCE cluster is wrong?

Pod corresponds to a container instance.

Pod is the smallest deployment unit that Kubernetes can create, schedule, and manage.

Pod is scheduled to the Node node and remains on this node until it is destroyed.

Containers in the same Pod share the same network namespace, IP address and port space and volume.
