Exam SY0-601 topic 1 question 3 discussion

its the way to distribute load across different servers, at the same time you can remove from the cluster each server that you want to update.

Based on the requirements provided, a Reverse Proxy would be the best choice to meet the objectives of both the Chief Security Officer and the security architect. Here's a breakdown of why each option may or may not suit your needs: A. Reverse Proxy: Increased Scalability: Reverse proxies can distribute incoming requests to various back-end servers, improving scalability and ensuring high availability. Flexibility for Updates: Since the reverse proxy handles client requests, backend servers can be taken down for maintenance or updates without causing service disruption. Reduced Server Resources: By caching content and offloading SSL termination, reverse proxies can reduce the load on back-end servers. Session Persistence Not Important: A reverse proxy can operate without needing to maintain session persistence, aligning with your requirement.

The Answer Is Definitely "C" snapshots and here is my reasons . 1- increased scalability and flexibility 2-allowing it to be updated and modified without disruption to services 3-reduce the back-end server resources 4-session persistence is not important All this key words refer to Snapshots . Reverse proxies are typically implemented to help increase security, performance, and reliability, and the Q here is asking for the 4 things up as mentioned in the reasons , this is why the Answer A is not related to the Q in as much as The answer C witch is Snapshots that provide both Flexibility and scalability , and it will allow you to modified and update your data without disruption to the service . and it's very light so it will not build up to the back-end resources .

A reverse proxy would be the best solution to meet the requirements described. A reverse proxy sits between the clients and the back-end servers, handling client requests on behalf of the servers. It provides increased scalability and flexibility by allowing the back-end infrastructure to be updated and modified without disruption to services. The reverse proxy can distribute client requests across multiple back-end servers, reducing the resource load on individual servers. Since session persistence is not important for the applications running on the back-end servers, the reverse proxy can handle the requests in a load-balanced manner without the need for session affinity. This allows for better resource utilization and flexibility in managing the back-end infrastructure.

A reverse proxy acts as an intermediary server between clients and back-end servers. It receives requests from clients, forwards those requests to the appropriate back-end servers, and then sends the responses back to the clients. Reverse proxies are often used for load balancing, security, and improving performance. 1. Increased scalability and flexibility: Reverse proxies can distribute client requests across multiple back-end servers, providing increased scalability. They also allow for easier modification and updating of the back-end infrastructure without disrupting services, as changes can be made to the back-end servers without affecting the clients directly. 2. Reduced back-end server resources: By distributing client requests across multiple back-end servers, a reverse proxy can balance the load, reducing the burden on individual back-end servers and optimizing resource utilization. 3. Session persistence not important: In some scenarios, session persistence is critical to maintain user state across requests. However, in this case, session persistence is explicitly stated as not important. This means the reverse proxy doesn't need to manage sticky sessions, further simplifying the setup.

Explanation: Reverse proxy: A reverse proxy sits in front of web servers and forwards client requests to the appropriate back-end servers. It can offload tasks such as SSL termination, caching, and load balancing from the back-end servers, reducing their workload and resource utilization. Additionally, reverse proxies can distribute traffic among multiple back-end servers, improving scalability and flexibility. Since session persistence is not important for the applications running on the back-end servers, the reverse proxy can distribute requests dynamically without needing to maintain session state, further reducing the burden on individual servers.

For anybody that knows Azure, by implementing an Application Gateway / WAF (reverse proxy), you can add /remove your backend servers (targets) into / out of your backend pool without disrupting your services. https://learn.microsoft.com/en-us/azure/application-gateway/overview

Answer is A. Snapshot do not provide scalability .

Light weight

reverse proxy takes the request and performs the load balancing and thus better resource utilization is achieved.

I chose B because it seems like the right answer

Chat GPT is also saying A

i answered A on the test

Answer:A

A is correct

A is defo the answer! I have no clue how a snap is going to do anything!

A reverse proxy would be the best solution for increased scalability and flexibility for back-end infrastructure. Explanation: Correct option Because a reverse proxy can give enhanced scalability and flexibility for back-end infrastructure .
