Alibaba Cloud CAP-C01 Dumps Questions Answers

ROS Stack Groups are specifically designed for centrally deploying a common Resource Orchestration Service template across multiple Alibaba Cloud accounts and regions. This makes option D the architecture that directly addresses both dimensions of the requirement: multi-account governance and multi-region infrastructure-as-code deployment.

Alibaba Cloud documentation states that stack instances belonging to a stack group can deploy stacks into destination accounts and different regions. With Resource Directory integration and service-managed permissions, trusted access can be enabled so that stack groups are operated by a management account or delegated administrator while deployments occur in organization member accounts.

Nested stacks are primarily a template-composition mechanism; they do not constitute centralized multi-account deployment orchestration. Manually combining ordinary ROS templates and RAM policies could technically enable cross-account operations, but it recreates functionality that Stack Groups provide natively and increases operational overhead. Resource Directory and Cloud Governance alone also do not replace the actual multi-account, multi-region stack deployment mechanism.

Therefore, Resource Directory establishes the organizational account structure while ROS Stack Groups provide repeatable infrastructure deployment across those accounts and target regions.

Express Connect with redundant connections is the strongest match for a mission-critical hybrid network requiring private connectivity, high availability, and enterprise-scale bandwidth. Express Connect establishes dedicated, secure, high-speed private connectivity between an on-premises data center and Alibaba Cloud VPC resources rather than transporting application traffic over the public Internet.

Alibaba Cloud ' s current Express Connect guidance identifies disaster recovery and high availability as primary enterprise scenarios. Redundant circuits and connection paths can protect connectivity against failures involving leased lines, devices, fiber cuts, and access points. Alibaba also identifies highly elastic, high-availability architectures based on dedicated connectivity and ECMP for environments with significant traffic requirements.

VPC peering connects VPC networks and does not independently provide an on-premises dedicated access circuit. VPN Gateway can connect an on-premises network to a VPC securely, but it uses Internet-based VPN transport and is generally not the strongest option where dedicated private connectivity, large scalable bandwidth, and robust path redundancy are explicit requirements. NAT Gateway provides address translation and Internet access functions rather than private hybrid connectivity.

Therefore, redundant Express Connect paths provide the enterprise-grade hybrid networking characteristics described.

Option B provides the simplest consolidated content-delivery architecture. Alibaba Cloud CDN can use multiple origins, and current CDN functionality supports origin-selection rules based on parameters such as request path, headers, query strings, and cookies. This allows static requests to be associated with an OSS origin while application requests are forwarded toward the ALB-backed application tier.

Static objects stored in OSS benefit directly from CDN edge caching. Requests are routed to nearby CDN points of presence, and cached resources can be returned without repeatedly accessing the OSS origin, reducing both latency and origin load.

Dynamic responses are generally not cached because they are generated uniquely for requests. They can still be routed to the application origin according to the configured origin rules.

The Global Accelerator alternatives create an unnecessarily fragmented architecture and attempt to use separate acceleration paths where one CDN-facing domain and origin-routing configuration can satisfy the question with fewer components. They also introduce additional DNS and acceleration configuration.

Therefore, a single CDN delivery layer with OSS and ALB-backed origins, combined with Alibaba Cloud DNS directing the application domain to CDN, produces the lowest configuration overhead.
