Try these sample questions to test your Tencent Cloud Developer Associate exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1You want to run backend logic without managing servers. Which Tencent Cloud service lets you upload code and execute it in response to HTTP requests or events?
A.CVM Standard S6
B.Serverless Cloud Function (SCF)
C.Tencent Kubernetes Engine (TKE)
D.Elastic MapReduce (EMR)
Explanation: SCF (Serverless Cloud Function) is Tencent Cloud's FaaS offering. You deploy code without provisioning servers, and the platform scales automatically. CVM is a virtual machine, TKE runs container workloads, and EMR handles big-data processing.
2An SCF function needs to be invoked every time a new object is uploaded to a COS bucket. Which trigger type should you configure?
A.COS trigger
B.API Gateway trigger
C.Timer trigger
D.CKafka trigger
Explanation: The COS trigger fires an SCF function when a configured event (e.g., ObjectCreated) occurs on a specific bucket. API Gateway triggers handle HTTP requests, Timer triggers schedule periodic invocations, and CKafka triggers respond to Kafka messages.
3Which Tencent Cloud service provides a fully managed RESTful API endpoint so your SCF functions can be called over HTTPS from a mobile app?
A.Cloud Load Balancer (CLB)
B.API Gateway
C.Content Delivery Network (CDN)
D.VPN Gateway
Explanation: API Gateway lets you publish, manage, and secure APIs backed by SCF, CVM, or other backends. It handles HTTPS termination, authentication, throttling, and SDK generation. CLB distributes traffic to compute resources; CDN caches static content; VPN Gateway creates encrypted tunnels.
4You are deploying a containerized microservice on Tencent Cloud and want the platform to manage the Kubernetes control plane. Which service should you choose?
A.CVM with self-installed Kubernetes
B.Tencent Kubernetes Engine (TKE) Managed Cluster
C.Elastic Kubernetes Service (EKS)
D.Tencent Container Registry (TCR)
Explanation: TKE Managed Cluster mode hands the Kubernetes API server and etcd control plane to Tencent Cloud, leaving you to manage only worker nodes and workloads. EKS (Elastic Kubernetes Service on Tencent Cloud) goes further by making nodes serverless. TCR is a container image registry, not a compute service.
5Your application stores user-generated images in COS. To serve them globally with low latency, which additional service should you enable?
A.Direct Connect
B.CDN acceleration for the COS bucket
C.Cloud Load Balancer Layer-7
D.CFS file system
Explanation: Enabling CDN acceleration on a COS origin distributes static content to edge nodes globally, reducing latency for end users. Direct Connect is for private enterprise network links, CLB distributes traffic to compute backends, and CFS is a shared NFS/SMB file system.
6A developer needs to grant an SCF function permission to write to a TencentDB table without hardcoding credentials. Which CAM feature enables this?
A.CAM sub-user with a long-term API key
B.Resource policy on the TencentDB table
C.CAM role bound to the SCF function execution identity
D.Account root key stored in an environment variable
Explanation: Binding a CAM execution role to an SCF function allows the function to assume temporary credentials scoped to only the permissions in that role's policy — no long-term secrets are embedded. Hardcoding root keys or sub-user keys in environment variables is a security anti-pattern.
7Which Tencent Cloud SDK feature automatically refreshes temporary credentials when an SCF execution role is used, without any code in the function?
A.Manual STS token refresh loop
B.SDK built-in credential provider chain
C.API key rotation via KMS
D.VPC endpoint for CAM
Explanation: The Tencent Cloud SDK uses a credential provider chain that automatically fetches and refreshes temporary STS credentials injected as environment variables when the function runs under an execution role. Developers do not need to write manual refresh logic.
8You want to store and retrieve application secrets (database passwords, API keys) securely at runtime without embedding them in code. Which Tencent Cloud service should you use?
A.COS bucket with private ACL
B.SSM Parameter Store
C.Secrets Manager (KMS-backed)
D.CVM user-data script
Explanation: Tencent Cloud Secrets Manager (part of the KMS product family) stores secrets encrypted at rest with KMS CMKs and provides SDK/API access at runtime with audit logging. Embedding secrets in user-data or COS objects is less secure and harder to rotate.
9Which COS presigned URL feature allows a frontend to upload a file directly to COS without routing the binary through your application server?
A.COS CORS policy
B.Presigned PUT URL
C.COS reverse proxy in CLB
D.COS Transfer Acceleration
Explanation: A presigned PUT URL is time-limited and grants the holder permission to upload one object directly to COS. The backend generates and signs the URL; the client uploads the file directly, offloading transfer bandwidth from your servers.
10Your SCF function processes messages from a TDMQ (CMQ) queue. The function keeps failing and the same message is retried indefinitely. How should you prevent poison messages from blocking the queue?
A.Increase the function timeout to 900 seconds
B.Configure a Dead Letter Queue (DLQ) for the TDMQ trigger
C.Set the SCF concurrency limit to 1
D.Switch to a Timer trigger
Explanation: A Dead Letter Queue captures messages that fail processing after the maximum retry count, removing them from the active queue so healthy messages are not blocked. Increasing timeout or limiting concurrency does not address a broken message. Switching to a timer trigger removes the event-driven architecture entirely.

Tencent Cloud Developer Associate Study Tips from Top Performers

1Focus heavily on SCF: understand all trigger types (COS, Timer, CKafka, API Gateway), execution roles vs. hardcoded keys, concurrency models, layers, and VPC integration
2Master API Gateway: service vs. API vs. environment hierarchy, CAM vs. API key authentication, CORS configuration, request parameter mapping, and usage plan throttling
3Practice Kubernetes fundamentals on TKE: ClusterIP for internal services, Ingress for external HTTP routing, ConfigMap vs. Secret for config and credentials, HPA for autoscaling
4Know COS features: storage class differences and minimum durations, lifecycle expiration, CRR for multi-region, presigned PUT for direct upload, and SSE-KMS for compliance
5Understand CKafka consumer group semantics: same group ID splits messages; different group IDs get independent copies — crucial for multi-service event bus design
