Salesforce Certified MuleSoft Integration Architect I Exam Practice Questions (P. 2)

A healthcare client must connect its Mule APIs that are deployed to CloudHub 1.0 to systems in an existing on-premises datacenter through private and secure connections.
Which network architecture supports these security requirements to connect the Mule APIs to the on-premises datacenter?

An organization uses a four-node customer-hosted Mule runtime cluster to host one stateless API implementation. The API is accessed over HTTPS through a load balancer that uses round-robin for load distribution. Each node in the cluster has been sized to accept four times the current number of requests.
Two nodes in the cluster experience a power outage and are no longer available. The load balancer detects the outage and blocks the two unavailable nodes from receiving further HTTP requests.
What performance-related consequence is guaranteed to happen, on average, assuming the remaining cluster nodes are fully operational?

A manufacturing company wants to share inventory updates with dealers D1 and D2 asynchronously and concurrently via Queues Q1 and Q2. Dealer D1 must consume the messages from the Queue Q1, and Dealer D2 must consume the messages from the Queue Q2.
Dealer D1 has implemented a retry mechanism to reprocess the transaction. In case of any errors while processing the inventory updates. Dealer D2 has not implemented any retry mechanism.
How should the dealers acknowledge the message to avoid message loss and minimize impact on the current implementation?

An organization plans to use the Anypoint Platform audit logging service to log Anypoint MQ actions.
What consideration must be kept in mind when leveraging Anypoint MQ Audit Logs?

A healthcare provider is implementing Anypoint Platform to manage its application infrastructure and is using the customer-hosted runtime for its business due to certain financial requirements it must meet. It has built a number of synchronous APIs and is currently hosting these on a Mule runtime on one server. These applications make use of a number of components, including heavy use of Object Stores and VM Queues.
Business has grown rapidly in the last year, and the healthcare provider is starting to receive reports of reliability issues from its applications. The DevOps team indicates that the APIs are currently handling too many requests, and this is overloading the server. The team has also mentioned that there is significant downtime when the server is down for maintenance.
What can the team add or upgrade to mitigate these issues?
