질문 # 11
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?
정답：C
설명：
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.

질문 # 12
A company is deploying a mission-critical application on Alibaba Cloud ECS instances that require high availability and failover capabilities. The application must remain accessible even if an entire zone fails.
Which deployment strategy should the company use to ensure high availability?
정답：B
설명：
A multi-zone deployment within the same region is the standard architecture for surviving the complete failure of one availability zone. Alibaba Cloud zones within a region are physically isolated for fault tolerance while maintaining high-speed internal network connectivity. Alibaba Cloud explicitly recommends deploying resources across different zones when higher disaster-recovery capability is required.
For an application tier, multiple ECS instances should be placed in separate zones and normally fronted by a multi-zone ALB or another suitable load-balancing service. Health checks ensure that traffic is no longer directed to unavailable instances, allowing surviving instances in another zone to continue serving requests.
Alibaba Cloud ' s current high-availability guidance specifically describes multi-zone ECS and load-balancer deployments as the architecture for resilience against data-center or zone failures.
Option A remains vulnerable because all compute resources share the same zone failure domain. Option C retains a single compute point of failure regardless of storage performance. Option D can protect against an entire regional disaster, but it adds substantially greater networking, data synchronization, routing, and operational complexity than is necessary for the stated requirement of surviving one zone failure.
Therefore, distributing ECS instances across multiple zones within one region is the correct high-availability strategy.

질문 # 13
You ' ve been hired to design a highly available application consisting of web, application, and database tiers.
HTTPS content delivery should be as close to the edge as possible, with the least delivery time.
Which of the following solutions meets these requirements and is MOST secure?
정답：D
설명：
Option B provides both an appropriate security boundary and an optimized delivery path. Alibaba Cloud CDN should be the Internet-facing content-delivery layer so that cacheable HTTPS resources are served from edge points of presence close to users. Alibaba Cloud currently supports directly configuring an ALB instance domain as a CDN origin, producing the request path client # CDN # ALB # backend server. This prevents clients from bypassing the load-balancing tier and preserves centralized health checking and traffic distribution.
The backend ECS instances should remain on private network addresses rather than being individually Internet-exposed. For an Internet-facing ALB, external traffic reaches the ALB through its public EIP and is then forwarded internally to backend ECS private IP addresses. This substantially reduces the attack surface while retaining public application availability.
Options C and D unnecessarily expose ECS instances through public networking. Option A uses private ECS instances, but making the individual application servers the CDN origins bypasses the ALB ' s centralized distribution and availability functions. Therefore, CDN # ALB # private ECS is the strongest architecture.

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?
정답：A
설명：
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.

FirstBuy is a rapidly growing global e-commerce company. The company hosts its web application on Alibaba Cloud. The application serves both static and dynamic content. Transactional data is stored in an ApsaraDB RDS database.
Lately, customers have been complaining about slow page loading speeds.
As a Cloud Architect, which combination of actions can you take to solve this problem? (Correct answers: 2)
정답：C,D
설명：
Alibaba Cloud CDN addresses the front-end performance problem by caching static resources at edge Points of Presence close to users. Instead of every image, JavaScript file, stylesheet, or other cacheable object being retrieved from the origin application, CDN returns cached copies from nearby edge nodes. This reduces network latency and decreases load on the original application servers. Alibaba Cloud specifically identifies reduced latency and lower origin workload as primary benefits of CDN.
Read/write splitting addresses database-side pressure. ApsaraDB RDS for MySQL can use database proxy functionality to direct write operations to the primary instance and distribute eligible read operations to read- only instances. This is especially effective for read-heavy web applications because it reduces CPU and I/O load on the primary database and increases aggregate read throughput.
A multi-zone database improves availability rather than directly solving page-load latency. AnalyticDB is an analytical database and should not replace RDS simply to handle transactional data. OSS is optimized for static objects; hosting dynamic application content there does not fit its object-storage model.
