質問 # 33
A Cloud Architect is designing a two-tiered architecture that includes a public vSwitch and a database vSwitch. The web servers in the public vSwitch must be open to the Internet on port 443. The ApsaraDB RDS for MySQL instance in the database vSwitch must be accessible only to the web servers on port 3306.
Which combination of actions should the Cloud Architect take to meet these requirements? (Correct answers:
2)
正解：B、C
解説：
The public web tier needs an inbound security-group rule permitting TCP 443 from Internet clients.
Therefore, Option E is required. Security groups act as virtual firewalls and should expose only application ports required by the workload. Alibaba Cloud recommends allowing public access only to necessary web- service ports such as HTTPS 443 while keeping internal services inaccessible from the Internet.
For the database tier, access should be limited to ECS instances belonging to the web-server security group.
Alibaba Cloud RDS for MySQL supports associating an ECS security group with an RDS instance, allowing ECS instances in that group to connect without adding every server address individually to an IP whitelist.
This is particularly useful when application-server membership changes dynamically.
Option B is overly broad because every resource within the public vSwitch ' s CIDR could potentially be authorized rather than only the approved web tier. Option C would prevent legitimate database traffic. Option D is unnecessary because RDS access behaves as an allow-list model: only explicitly authorized addresses or associated security-group members should be granted database access.
Thus, Internet clients reach the web tier only over HTTPS, while MySQL accepts access only from the authorized application servers.

質問 # 34
Muthu is a Cloud Architect who is designing the architecture of a new application being deployed to Alibaba Cloud. The application will run on Elastic Compute Service (ECS) pay-as-you-go instances and will automatically scale across multiple zones based on load. The ECS cluster will scale in and out frequently throughout the day. An Application Load Balancer (ALB) will handle the load distribution. The architecture needs to support distributed session data management.
What should Muthu do to ensure that the architecture supports distributed session data management?
正解：A
解説：
Tair (Redis OSS-Compatible) is the appropriate centralized session-state layer for an elastic, distributed application. When ECS instances frequently scale in and out, application sessions must not depend on the lifecycle of any individual compute node. By storing session tokens and session state in Tair, every ECS instance can retrieve the same session information, making the web/application tier effectively stateless and compatible with Auto Scaling.
Alibaba Cloud Tair is a fully managed Redis-compatible database designed for high throughput, low latency, elastic scalability, and high availability. Alibaba Cloud also documents session-oriented Tair use cases in which session tokens are stored as Redis/Tair data structures with TTL values, demonstrating precisely why the service fits distributed session management.
Session stickiness is weaker because it attempts to keep a user on a specific backend and therefore creates affinity to an instance that might be removed during scaling or failover. CloudMonitor is an observability service, not a session store. STS issues temporary Alibaba Cloud credentials and does not maintain application user sessions.
Consequently, separating session state from ECS compute by storing it in Tair gives the architecture the elasticity and fault tolerance required.

質問 # 35
A global hotel chain is migrating its reservation system to Alibaba Cloud. The system must provide high availability across multiple regions, ensure data consistency, and support real-time updates to prevent double bookings. Additionally, the system should integrate with third-party payment gateways securely.
Which combination of Alibaba Cloud services should the hotel chain implement to architect this reservation system effectively? (Correct answers: 3)
正解：A、C、D
解説：
Option A refers to PolarDB Global Database Network (GDN), Alibaba Cloud ' s architecture for connecting PolarDB clusters across regions. A GDN contains a primary cluster and secondary regional clusters. Data changes are continuously replicated, local reads can be served by regional clusters, and write operations are routed to the primary cluster. Maintaining a single authoritative write path is particularly important for reservation transactions where concurrent booking operations must be controlled consistently.
Option C provides resilient application capacity by deploying ECS application servers in multiple regions and using ALB within each regional deployment to distribute requests among healthy instances. In a complete production implementation, a global routing mechanism such as DNS traffic management or Global Accelerator would normally direct users between those regional application stacks.
Function Compute is suitable for payment-gateway integrations because payment callbacks and API interactions are event-driven or request-driven workloads. Function Compute can be exposed securely through API Gateway, which provides routing, authentication, traffic control, and API management without persistent integration servers.
OSS versioning is useful for protecting stored objects but does not supply the transactional database, regional application availability, or payment-processing functionality required here.

質問 # 36
A multinational corporation is designing its network architecture on Alibaba Cloud to support its distributed applications. Their requirements include:
* Private and high-speed connectivity between on-premises data centers and Alibaba Cloud VPCs across multiple regions.
* Centralized management and enforcement of network security policies.
* Comprehensive monitoring and logging of all network traffic for compliance and auditing purposes.
Which combination of Alibaba Cloud services should the corporation implement to meet these requirements MOST effectively? (Correct answers: 2)
正解：A、D
解説：
Express Connect and CEN Transit Router provide the enterprise networking foundation required for a multinational hybrid environment. Express Connect gives the company ' s on-premises infrastructure dedicated private connectivity to Alibaba Cloud. A Virtual Border Router can then attach to a CEN Transit Router, allowing the data center to communicate privately with VPCs in the same region and across other regions.
CEN provides centralized routing for VPCs, VBRs, inter-region connections, and other network attachments.
This avoids the operational complexity and poor scalability of maintaining large meshes of VPC peering links or independent VPN connections.
For network visibility, CEN Transit Router flow logs integrate directly with Simple Log Service. These flow logs capture five-tuple traffic information, bytes, packets, and connection details and deliver the records to SLS for monitoring, troubleshooting, compliance analysis, and long-term querying.
Security Center supplements this design by providing centralized security posture and workload-security management. In a comprehensive enterprise implementation, network access controls and security policies are applied alongside this centralized connectivity architecture.
VPC peering becomes difficult to administer at multinational scale, individual VPN gateways add operational complexity, and Global Accelerator is designed primarily to accelerate application access rather than replace an enterprise hybrid WAN.

質問 # 37
Kimiko works for a multinational retail chain that has just extended its internal business management services to Alibaba Cloud. They want to ensure the security and high-speed connectivity between its on-premises data center and multiple VPCs across different regions on Alibaba Cloud. The company wants to minimize network latency and ensure high availability without managing individual VPN connections for each VPC.
Which Alibaba Cloud service should the company use to achieve this goal?
正解：B
解説：
Express Connect combined with Cloud Enterprise Network Transit Routers provides the appropriate enterprise hybrid-network architecture. Express Connect establishes a dedicated private circuit from the on- premises data center to Alibaba Cloud, providing lower latency, predictable performance, high bandwidth, and reduced exposure compared with Internet-based VPN connectivity.
The Express Connect circuit terminates through a Virtual Border Router. That VBR can be attached to CEN, where Transit Routers provide hub-and-spoke connectivity to multiple VPCs instead of requiring separate point-to-point connections for every VPC. Transit Routers can connect VPCs, VBRs, VPN attachments, and inter-region Transit Routers, enabling centralized routing across a geographically distributed enterprise network.
Alibaba Cloud also supports connecting an on-premises VBR and multiple VPCs to a Transit Router so that all attached networks communicate over private connectivity. Cross-region CEN connections then extend the architecture to VPCs in additional regions.
VPN Gateway relies on Internet-based encrypted tunnels and would require more tunnel management at scale.
NAT Gateway performs address translation and does not provide private hybrid interconnection. Apsara Stack is an on-premises cloud platform rather than the required connectivity service.
