An application runs on an Elastic Compute Service (ECS) with an Elastic IP address in VPC A within Alibaba Cloud. The application requires access to a database in VPC B. Both VPCs are in the same Alibaba Cloud account.
Which of the following solutions will provide the required access MOST securely?

• A.Launch an ECS instance with an Elastic IP address into VPC B. Proxy all requests through the new ECS instance.
• B.Make the database instance publicly accessible. Assign a public IP address to the database instance.
• C.Configure a VPC peering connection between VPC A and VPC B.
• D.Create a security group for the database that allows all traffic from the public IP address of the application server in VPC A.

A media company is developing a video processing pipeline utilizing Alibaba Cloud Container Service for Kubernetes (ACK). They want to use a serverless approach to accommodate unpredictable workloads but are unsure about its impact on logging.
What considerations should the company keep in mind regarding logging in a serverless ACK environment?

• A.Presume that real-time log analysis will be limited and avoid real-time analytics.
• B.Use Application Real-time Monitoring Service to implement resource monitoring.
• C.Utilize SLS for its seamless integration, capturing logs without infrastructure management complexity.
• D.Anticipate increased latency in logging due to scaling events and prioritize using dedicated resources.

Priya is building a remote office application, and is looking for a storage solution to go with it. The solution must be highly available and scalable, and must be able to function as a file system that can be mounted to multiple Linux instances on Alibaba Cloud, as well as on-prem machines using native protocols such as Network File System (NFS) or Server Message Block (SMB).
For ease of use, Priya has set up a VPN Gateway between their network and their application ' s VPC on Alibaba Cloud.
Which of the following storage solutions meets this requirement?

• A.Object Storage Service (OSS) with buckets deployed in multiple regions
• B.Elastic Block Storage (EBS) disks attached to Elastic Compute Service (ECS) instances serving as proxies
• C.File Storage NAS with single mount points
• D.File Storage NAS with multiple mount points

An application runs on an ECS instance in a VPC. The application reads and processes logs that are stored in an OSS bucket in the SAME region. For security reasons, the ECS instance needs to access the OSS bucket without connectivity to the Internet.
Which of the following solutions can BEST provide private network connectivity to OSS?

• A.Directly access the OSS bucket from ECS via OSS ' s internal endpoint.
• B.Create a gateway endpoint in VPC and use that endpoint to access OSS.
• C.Use PrivateLink to create a connection between the VPC and OSS.
• D.Use VPN Gateway to establish an IPsec-VPN connection between the VPC and OSS.

Clarence runs a retail company that hosts an e-commerce website on Alibaba Cloud across multiple Alibaba Cloud regions. Clarence wants the website to be operational at all times to ensure customers can make purchases around the clock. The website stores data in a PolarDB for MySQL instance.
Which of the following solutions will provide the HIGHEST availability for the database?

• A.Create two PolarDB for MySQL clusters configured with read/write splitting in two different regions.
  When a region fails, use Function Compute to replicate the data in the read-only nodes to the healthy region. Then, configure the website to fail over to the healthy region.
• B.Deploy the Cluster Edition of PolarDB for MySQL to ensure that the system can elect a new primary node from read-only nodes when the primary node fails. Ensure that the website is configured to reconnect to the cluster after the failover.
• C.Utilize the Global Database Network (GDN) to establish cross-region clusters for PolarDB, enabling both read and write operations across multiple regions. In case of a failure, seamlessly direct traffic to a secondary region that can serve as the primary node, maintaining high availability and minimal downtime.
• D.Configure cross-region backup and restoration in PolarDB. During disruptions, restore the latest backup set to a new PolarDB cluster in another region. Redirect application traffic to this restored cluster and configure read/write splitting for this cluster.
