H13-821_V3.0-ENU試験無料問題集「Huawei HCIP-Cloud Service Solutions Architect V3.0 認定」

A. The IoT data analysis service adopts a graphical binge method, and has rich words calculation operators, which can seamlessly connect with AI

B. Device access service IOTDA supports billion-level device access and millions-level high concurrency

C. If you build an IOT management platform on HUAWEI CLOUD, you can also choose HUAWEI CLOUD AppCube to realize visualization, and use the message notification service SIN to complete message notification

D. The global SIN connection service provides network traffic for device data transmission to the cloud. There are three operators to choose from. When switching operators, you need to change the card

A. When creating a peer-to-peer connection between VPCs, by default a VPC cannot access the public network through the EIP of another VC

B. If the CIDR of the VPC has a heavy committee, but the subnets do not overlap, then a peer-to-peer connection can be established between the VPCs

C. Considering the high availability of business, multiple VPC peering connections can be established between VPCs at the same time

D. After the peer-to-peer connection is established, it is necessary to add routes to the UPCs at both ends to communicate

A. Auto-negotiation must be disabled for the port, and the port speed and full-duplex mode must be manually configured

B. Users must use single-mode 1 GE or 10 GE optical modules to connect to Huawei Cloud access devices

C. It is recommended to use public IP addresses on and off the cloud, and the intercommunicating IP network segments cannot conflict

D. Must support 802.1Q VLAN encapsulation across the entire connection (including intermediate devices)

A. Cloud application service grid development framework is not limited to language

B. It is necessary to integrate the Istio Community Edition SDK to realize application access

C. Provide integrated solutions for traditional microservice SDKs such as Spring Cloud and Dubbo

D. Ability to provide container-based gray scale publishing and traffic management

A. True

B. False

A. All update operations are only logged, and Double write is no longer required. Reduced valuable network bandwidth

B. There is no longer a standby database, and all read-only databases are in the Active state. And bear the read traffic, making resource utilization higher

C. There is only one copy of storage, no need to purchase additional storage. If there are more read-only nodes, the storage cost will be saved more

D. With multiple storages, when the access volume is large, the read and write performance of the database will be significantly improved

A. True

B. False

A. Control the management authority of the data replication service DRS through the unified identity authentication service IAM

B. Encrypt sensitive and private data and save it in the database

C. Use SSL channel to ensure data transmission encryption

D. Use Security Groups to Ensure Access Sources Are Trusted

A. Costs can continue to be reduced through continuous monitoring and flagging

B. Plan to implement Auto Scaling for as many ECS workloads as possible so that you can scale out when needed and automatically spend less when you don't need that resource. Additionally, non-production workloads can be automatically shut down when not in use

C. HUAWEI CLOUD provides a variety of purchase methods, based on the business usage scenario and continuous cycle, purchase in the best way. For example: the pay-as-you-go model is recommended for applications requiring capacity reservations, applications with stable usage status

D. One should benchmark the application environment and choose the correct instance type based on how the workload uses CPU, RAM, network, storage size I/O

A. Call chain tracking: Automatically sample certain requests, collect the call relationship between services of a single request and the health of intermediate calls, and realize automatic tracking of global call links

B. Application indicator monitoring: automatic monitoring of a large number of application-related monitoring indicators, such as JVM, Tomcat, Mysql, Redis, kafka, etc.

C. Application topology: through dynamic analysis and intelligent calculation of RPC call information, the topological relationship between distributed applications is automatically generated

D. Site monitoring: By installing the cloud monitoring service Agent plug-in in the cloud service, monitor and count the log content, set alarm rules and other operations

A. When creating an elastic cloud server ECS, it will have its own system disk, which needs to be initialized before it can be used

B. Create a data disk separately, and then mount the data disk to the elastic cloud server ECS. The data disk does not need to be initialized

C. The data disk is mounted to the elastic cloud server ECS and can only be used after initialization

D. When creating an elastic cloud server ECS, it will have its own system disk and will be automatically initialized
