CEA-C01 practice question 5 of 10

Which service supports HTTPS load balancing?

Full set: 49 questions

Answer options

A: SLB Correct answer

B: OSS

C: RDS

D: ECS

Correct Answer:

A. SLB

Explanation

Alibaba Cloud Server Load Balancer (SLB) distributes incoming application traffic across multiple backend Elastic Compute Service (ECS) instances. SLB supports Layer 4 (TCP/UDP) and Layer 7 (HTTP/HTTPS) load balancing protocols, allowing SSL offloading, certificate management, and secure HTTPS traffic distribution to maintain high availability and fault tolerance for web applications.

Why Incorrect

Option B: Object Storage Service (OSS) is an encrypted object storage service for unstructured data, not a load balancing service.
Option C: ApsaraDB for RDS is a managed relational database service and does not manage or balance incoming HTTPS web traffic.
Option D: Elastic Compute Service (ECS) provides virtual compute nodes that host applications, but does not natively distribute external network load across multiple instances.
