An insurance 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 API's 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 insurance provider is starting to receive reports of reliability issues from its applications.
The DevOps team indicates that the API's are currently handling too many requests and this is over loading the server. The team has also mentioned that there is a significant downtime when the server is down for maintenance.
As an integration architect, which option would you suggest to mitigate these issues?

1. A. Add a load balancer and add additional servers in a server group configuration
2. B. Add a load balancer and add additional servers in a cluster configuration
3. C. Increase physical specifications of server CPU memory and network
4. D. Change applications by use an event-driven model

Correct Answer: B

As a part of business requirement , old CRM system needs to be integrated using Mule application. CRM system is capable of exchanging data only via SOAP/HTTP protocol. As an integration architect who follows API led approach , what is the the below step you will perform so that you can share document with CRM team?

1. A. Create RAML specification using Design Center
2. B. Create SOAP API specification using Design Center
3. C. Create WSDL specification using text editor
4. D. Create WSDL specification using Design Center

Correct Answer: C
Correct answer is Create WSDL specification using text editor SOAP services are specified using WSDL. A client program connecting to a web service can read the WSDL to determine what functions are available on the server. We can not create WSDL specification in Design Center. We need to use external text editor to create WSDL.

What is true about the network connections when a Mule application uses a JMS connector to interact with a JMS provider (message broker)?

1. A. To complete sending a JMS message, the JMS connector must establish a network connection with the JMS message recipient
2. B. To receive messages into the Mule application, the JMS provider initiates a network connection to the JMS connector and pushes messages along this connection
3. C. The JMS connector supports both sending and receiving of JMS messages over the protocol determined by the JMS provider
4. D. The AMQP protocol can be used by the JMS connector to portably establish connections to various types of JMS providers

Correct Answer: C
* To send message or receive JMS (Java Message Service) message no separate network connection need to be established. So option A, C and D are ruled out.
Correct Answer The JMS connector supports both sending and receiving of JMS messages over the protocol determined by the JMS provider.
* JMS Connector enables sending and receiving messages to queues and topics for any message service that implements the JMS specification.
* JMS is a widely used API for message-oriented middleware.
* It enables the communication between different components of a distributed application to be loosely coupled, reliable, and asynchronous.

An application deployed to a runtime fabric environment with two cluster replicas is designed to periodically trigger of flow for processing a high-volume set of records from the source system and synchronize with the SaaS system using the Batch job scope
After processing 1000 records in a periodic synchronization of 1 lakh records, the replicas in which batch job instance was started went down due to unexpected failure in the runtime fabric environment
What is the consequence of losing the replicas that run the Batch job instance?

1. A. The remaining 99000 records will be lost and left and processed
2. B. The second replicas will take over processing the remaining 99000 records
3. C. A new replacement replica will be available and will be process all 1,00,000 records from scratch leading to duplicate record processing
4. D. A new placement replica will be available and will take or processing the remaining 99,000 records

Correct Answer: B
