Question 1
- A game company recently released a new online game product, which was warmly welcomed by users after its launch. However, during the evening rush hour, users often log in congestion and cannot access the system normally, and the user experience feedback is poor. The company asked to resolve this issue quickly, and as the company's IT architect, which of the following would be the appropriate solution? Multiple selection
  
  A :
  Performance can be scaled by adding more servers to the load-balanced network so that accepted requests can be distributed to different back-end systems according to policy
  
  B :
  Replace one large resource with multiple small resources to reduce the impact of a single failure on the entire system
  
  C :
  Build the system on the cloud's dynamically scalable architecture that supports a good user experience and streaming Growth in volume or data size does not degrade performance
  
  D :
  Interdependencies in the system should be reduced. allowing various components to pass only through specific. technology-independent interfaces (e.g., RES TFUL API). Interact with each other. Technical implementation details are hidden so that the underlying implementation can be modified without affecting other components
  
  Answer: A,B,C,D
Question 2
- What are the correct descriptions of the typical three-tier architecture of cloud computing? Select
  
  A : In the data layer, we recommend that you directly use HUAWEI CLOUD APS
  
  B : You can save data archive logs or logical backups in VBS EVS Disk Backup Service
  
  C :
  Use Auto Scaling AS to ensure self-healing and adaptive service load of web server and application server nodes
  
  D : ECS at the same layer recommends affinity deployment
  
  Answer: A,C
Question 3
- Which of the following errors is the following description of the pods in a HUAWEI CLOUD CCE cluster? Single selection
  
  A : The pod corresponds to a container instance
  
  B : Share the same f network namespace, IP address, port space and volume with the container in the f pod
  
  C : Pod is the smallest deployment unit that Kubernetes can create, schedule, and manage
  
  D : Pods are scheduled to node nodes and remain on this node until they are destroyed
  
  Answer: A
Question 4
- A large enterprise is planning to migrate its entire internal business system to HUAWEI CLOUD to save overall data IT Procurement costs and operational costs. In terms of security, the company made two requirements:1, Because the administrator often travels, it needs to be supported Hold on to a long distance The security operation and maintenance of the process;2Multiple subsystems are used independently by different departments, and network isolation between subsystems is required; The following is depicted Describe what can meet the company's needs? Multiple selection
  
  A :
  Create multiple ECS instances under a VPC to install subsystems used by different departments, and assign only private IP addresses to all ECS instances and put them into unique security groups
  
  B :
  Establish a separate bastion host for remote login and O&M, and authorize the bastion host to access other subsystems ECS
  
  C :
  Use the security group feature in VPC to put ECS instances running different subsystems into dedicated security groups
  
  D :
  When the VPN tunnel service is enabled the administrator uses VPN encrypted communication during operation and maintenance
  
  Answer: B,C,D
Question 5
- For traditional data center customers migrating to the cloud which of the following services are required to ensure smooth migration and scalability of cloud architecture?
  
  A :
  L2CG: Interconnect to the second-layer networking of the data center to ensure that the migration IP address remains unchanged
  
  B : Private line: docking to the data center to provide a stable data transmission channel
  
  C : VPC: Refer to the data center component architecture to reasonably plan VPC subnets on the cloud
  
  D : DNS: Configure external domain name and map public network address
  
  Answer: A,B,C
