A company is implementing a publish-subscribe (Pub/Sub) messaging component by using Azure Service Bus. You are developing the first subscription application. In the Azure portal you see that messages are being sent to the subscription for each topic. You create and initialize a subscription client object by supplying the correct details, but the subscription application is still not consuming the messages. You need to ensure that the subscription client processes all messages. Which code segment should you use? A. await subscriptionClient.AddRuleAsync(new RuleDescription(RuleDescription.DefaultRuleName, new TrueFilter())); B. subscriptionClient = new SubscriptionClient(ServiceBusConnectionString, TopicName, SubscriptionName); C. await subscriptionClient.CloseAsync(); D. subscriptionClient.RegisterMessageHandler(ProcessMessagesAsync, messageHandlerOptions); Â Suggested Answer: D Using topic client, call RegisterMessageHandler which is used to receive messages continuously from the entity. It registers a message handler and begins a new thread to receive messages. This handler is waited on every time a new message is received by the receiver. subscriptionClient.RegisterMessageHandler(ReceiveMessagesAsync, messageHandlerOptions); Reference: https://www.c-sharpcorner.com/article/azure-service-bus-topic-and-subscription-pub-sub/ This question is in AZ-204: Developing Solutions for Microsoft Azure Exam For getting Microsoft Azure Developer Associate Certificate Disclaimers: The website is not related to, affiliated with, endorsed or authorized by Microsoft.
