__________feature in Server Load Balancer means that it can forward the access requests from a single user to the same ECS instance within a certain period to ensure session continuity.

Show Suggested Answer Hide Answer
Suggested Answer: A

Session persistence feature in Server Load Balancer means that it can forward the access requests from a single user to the same ECS instance within a certain period to ensure session continuity. This feature is useful for applications that require users to maintain a stateful connection with the backend servers, such as online shopping or banking. Session persistence can be enabled by configuring a cookie timeout period or a source IP hash method in the Server Load Balancer console.Reference:ACA Cloud Computing Certification - Alibaba Cloud Academy,Server Load Balancer - Alibaba Cloud Academy, Session Persistence - Alibaba Cloud Documentation Center

Least connections scheduling seems off too. I feel like session persistence is definitely the right term here, but I could be wrong.

Weighted Round Robin was mentioned in a similar question, but I don’t think it relates to keeping a user connected to the same instance.

I remember discussing health checks, but that doesn't seem to fit this question. It’s more about monitoring than session continuity.

I think the answer might be session persistence, but I'm not completely sure. It sounds familiar from our last practice session.

Session persistence, that's the one! I remember learning about that in class. The load balancer keeps track of which server instance a user is connected to and routes their requests to the same instance to maintain their session. Feels good to know I've got this one.

I'm a little confused by the wording of this question. Is it asking about a specific feature of the load balancer, or just generally how load balancers handle user sessions? I'll have to think this through carefully.

Okay, I think I've got this. The key here is that the question is asking about a feature that ensures session continuity, so it's got to be session persistence. That makes the most sense to me.

Hmm, I'm a bit unsure about this one. I know session persistence has something to do with maintaining user sessions, but I'm not totally confident in my understanding of how it works with a load balancer.

I'm pretty sure this is about session persistence, which is the feature that keeps a user connected to the same server instance during their session.

Least connections scheduling? Sounds like the instances are playing a game of 'who's got the fewest clients'.
