Exam AZ-204 topic 6 question 8 discussion

Create a single Service Bus Namespace. Create a single Service Bus Topic. Create a Service Bus subscription for each restaurant for which a driver can receive orders.

Correct. If you create only one topic there won't be any filtering of messages depending on the restaurant. So every driver will have access to all the the orders. With a topic by restaurant, message from one restaurant will go to only one topic, from which the driver can choose to subscribe.

The correct sequence of actions to implement an Azure Service Bus solution for this scenario would be: 1. Create a single service bus Namespace: A namespace is a container for all messaging components. It provides a unique scoping container, in which you can create queues, topics, and subscriptions. 2. Create a single service bus topic: A topic is a communication channel in Azure Service Bus that sends messages to multiple subscriptions. In this case, orders are sent to the topic. 3. Create a service bus subscription for each restaurant for which a driver can receive orders: A subscription is a named, independently configurable entity within a topic. Each driver can have a subscription for each restaurant they deliver for, allowing them to receive only the orders for those restaurants.

Create a single Service Bus Namespace. Create a single Service Bus Topic. Create a Service Bus subscription for each restaurant for which a driver can receive orders. Topics are used for one-to-many communication with multiple subscribing systems. By creating a topic for each restaurant, you can efficiently route messages (orders) to drivers who have selected that they will deliver orders for those restaurants. This setup allows for orders to be sent to a specific set of drivers (those interested in deliveries for a particular restaurant).

Create a single Service Bus Namespace. Create a single Service Bus Topic. Create a Service Bus subscription for each restaurant for which a driver can receive orders. Explanation: we create different topics if we are having different categories of messages such as Consider an e-commerce platform that handles order notifications, inventory updates, and customer support messages. Using separate topics, such as "order-notifications," "inventory-updates," and "customer-support-messages," allows for clear separation of message categories and efficient routing to respective consumers. However in this case, we don't have different topics, we only have one topic which is order processing and we can enable partioning on this topic so messages can be under the same partion with the restaurant id

On exam 3-Nov-2023. Went with most-voted answer - 932/1000. 1) single namespace 2) single topic 3) subscription for each restaurant.

I got this question (12-Aug-2023) and I chose the given answers - 932 passed

This was on the exam (July 2023). Went with single/single/subscription for each restaurant. Scored 917

Correct 1: Namespace is about the solution 2: Topics are about restaurant messages 3: Subscriptions are about driver's orders

The provided answer is the most correct. There is a 2000 subscription limit for topics, so you would only allow 2000 drivers TOTAL for the entire app if you chose this as a solution. You need one topic per restaurant or the application cannot scale. You can absolutely have 1 topic, that will still work as intended, it's just not the best solution.

It's the same question in ESI. The given answer is the same as highly voted.

BUDDIES, listen listen.. 1. Single Service Bus Namespace 2. Topic per restaurant (10k limit of restaurants). (A single topic would work, but requires subscription filters or another component to decide which drivers receive which restaurant orders. But this isn't specified so imo not an option) 3. Single subscription per topic. Each drivers who wants to deliver for a restaurant will periodically peek the subscription for messages (no lock, message not removed). Once they decide they want to deliver the order, they dequeue the message and away they go, other drivers who attempt to do so will not be able to. (At first, I also thought multiple subscriptions - but this introduces another complexity of syncing the orders across all the subscriptions if someone accepts the order delivery first... how can we notify other subscriptions? we can't.) All in all, agree the solution sucks a$$ but this is the best bet.
