• Question 143:

  A company plans to migrate to the cloud and now needs to migrate its offline business to the cloud. After investigation, it has identified two possible solutions: migration using the SMS Host Migration Service and migration through image import. Which of the following comparative analyses of the two methods is correct?

  A. The image import service has a longer service interruption time because it needs to create an image, while the Host Migration Service performs real-time data synchronization and only requires stopping the service during the final cutover for synchronization, resulting in a shorter interruption time.
  B. The image import service requires payment, while the SMS Host Migration Service is free.
  C. The SMS Host Migration Service can import encrypted files to the cloud, but the image import method cannot process encrypted files.
  D. The image import method requires installing an Agent in the OS in advance, while the SMS Host Migration Service does not.
  A. The image import service has a longer service interruption time because it needs to create an image, while the Host Migration Service performs real-time data synchronization and only requires stopping the service during the final cutover for synchronization, resulting in a shorter interruption time.

• Question 144:

  The operation team of an e-commerce company intends to collect the source IP addresses of customers for statistical analysis. However, after the service is connected to Anti-DDoS Pro, the real source IPs are hidden after traffic is forwarded to the server. As the company's technical leader, which of the following methods can be used to solve this problem?

  A. Obtain the source IP address through the Anti-DDoS Pro TOA plug-in.
  B. Obtain the source IP address through the CTS service.
  C. Obtain the source IP address through the AOM service.
  D. Obtain the source IP address through the HSS service.
  C. Obtain the source IP address through the AOM service.

• Question 145:

  In the migration delivery project, the correct project process is:

  Information research Runbook production Migration implementation Cutover and launch.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 146:

  A company plans to migrate its Oracle RAC service, which was originally deployed in the on-premises IDC data center, to HUAWEI CLOUD. Which types of cloud servers are suitable for this scenario? (Choose two)

  A. General-Purpose Compute Enhanced C6
  B. Graphics-Accelerated P1i2
  C. Bare Metal Server S4
  D. General Entry T6
  A. General-Purpose Compute Enhanced C6
  C. Bare Metal Server S4

• Question 147:

  Which of the following items is not a performance bottleneck for services in low-latency scenarios?

  A. Delay caused by long execution time of SQL statements
  B. Unreasonable selection of resource specifications, resulting in wasted resources and inter-process calls leading to performance bottlenecks
  C. Network latency caused by too many forwarding nodes in the network link
  D. The return result of data reading and writing takes too long
  B. Unreasonable selection of resource specifications, resulting in wasted resources and inter-process calls leading to performance bottlenecks

• Question 148:

  When using Cloud Data Migration (CDM), the following potential threats may exist:

  Internet threats: Malicious users may attack CDM through the CDM control console.

  Data center threats: Malicious CDM administrators may attempt to obtain users' data source access information.

  Malicious user threats: Malicious users may steal other users' data.

  Data exposure threats: Data leakage may occur when data is migrated over the public network.

  To mitigate these risks, which of the following mechanisms does CDM provide to help protect end users? (Choose four)

  A. CDM uses a separate virtual machine for each user to run its own CDM instance. The instances between users are completely isolated and secure, ensuring that a malicious user cannot access another user's instance.
  B. Users must provide the access username and password information of both the source and destination data sources to the CDM system to complete data migration. CDM provides a three-level protection mechanism to prevent CDM administrators from accessing this information or attacking users' critical data sources.
  C. Under the extract瓀rite model of CDM, even if CDM is bound to an Elastic IP, the ports are not opened to the Elastic IP, preventing attackers from accessing or attacking CDM through it. However, when migrating data over the public network, because user data sources are exposed on the public network and subject to third-party attacks, it is recommended to protect the source server using an access control (AC) domain firewall, such as allowing access requests only from EIPs bound to CDM.
  D. You cannot log in to the CDM console directly through the Internet. CDM provides a two-tier security mechanism to ensure secure access control.
