Question 1

The cloud-native data lake solution in HUAWEI CLOUD MapReduce provides a leading architecture for separating storage and computing for unstructured data scenarios such as massive government images and videos. Use OBS on the cloud to replace MRS local storage as a big data store. The following description of the OBS service in this solution, which one is wrong? Single selection

Options :

A : Replace the EC algorithm with three copies to reduce the unit capacity cost

B : Provide standard storage, low-access storage, and archive storage in three categories

C : Technology needs to be expanded separately

D : Distributed architecture, horizontally scalable

Answer: A

Question 2

The service data system of a department is already running on HUAWEI CLOUD but the response time of user feedback query response is high, which affects the user experience. As a cloud service architect, which of the following bumps should you take to solve this problem?

Options :

A :

The best solution for a particular system will vary depending on the workload type, using data to optimize the choice of resource type and configuration options

B :

Set up performance metrics and monitoring metrics to capture key performance indicators, and use visualization techniques to identify performance issues, hot spots, wait states, or low utilization

C : Use messaging middleware to put frequently accessed data in the Distributed Cache service Redss

D :

By introducing redundancy to eliminate single points of failure, when one fails, the true surplus can simply absorb a larger share of the work

Answer: A,B,C

Question 3

For a critical application, the customer requires the deployment of a fault-tolerant architecture that can achieve RTO=0. Plan to choose C6 2xlarge. 4 types of elastic ECSs, it is estimated that at least 6 ECSs are required for this service. From an architect's point of view, which of the following architectures can meet the above requirements and provide the best overall capabilities? Single selection

Options :

A :

Deploy 6 servers in each of the three zones, and use auto scaling to ensure that nodes can be replaced after damage

B :

Deploy three servers in each of the two zones and use auto scaling to ensure that nodes can be replaced after they are damaged

C :

Deploy 6 servers in each of the two zones and use auto scaling to ensure that nodes can be replaced after damage

D :

Deploy three servers in each of the three zones and use auto scaling to ensure that the can be replaced after the node is damaged

Answer: D

Question 4

During the research stage of business migration to the cloud enterprises need to collect source-end system information. The following description of the source information that needs to be collected. which is wrong?

Options :

A : You need to collect the effective data amount and disk size of the source host teaching disk

B : You need to collect the kernel version of the source host operating system

C : The network bandwidth from the source host to the target platform needs to be collected

D : You need to collect the average usage during the CPU-day period of the source host

Answer: D

Question 5

The biggest contribution of MapReduce is to realize automatic algorithm parallelization and large-scale distributed computing through a simple interface, which of the following scenarios is it suitable for?

Options :

A : Massive data search

B : Real-time retrieval

C : Web Access Log Analysis

D : Word frequency analysis
