NEW QUESTION # 25
What is a key difference between synchronous and asynchronous logging from Mule applications?

• A. Asynchronous logging produces more reliable audit trails with more accurate timestamps
• B. Synchronous logging writes log messages in a single logging thread but does not block the Mule event being processed by the next event processor
• C. Synchronous logging within an ongoing transaction writes log messages in the same thread that processes the current Mule event
• D. Asynchronous logging can improve Mule event processing throughput while also reducing the processing time for each Mule event

Answer: D

Explanation:
Explanation
Types of logging:
A) Synchronous: The execution of thread that is processing messages is interrupted to wait for the log message to be fully handled before it can continue.
The execution of the thread that is processing your message is interrupted to wait for the log message to be fully output before it can continue Performance degrades because of synchronous logging Used when the log is used as an audit trail or when logging ERROR/CRITICAL messages If the logger fails to write to disk, the exception would raise on the same thread that's currently processing the Mule event. If logging is critical for you, then you can rollback the transaction.

B) Asynchronous:
The logging operation occurs in a separate thread, so the actual processing of your message won't be delayed to wait for the logging to complete Substantial improvement in throughput and latency of message processing Mule runtime engine (Mule) 4 uses Log4j 2 asynchronous logging by default The disadvantage of asynchronous logging is error handling.
If the logger fails to write to disk, the thread doing the processing won't be aware of any issues writing to the disk, so you won't be able to rollback anything. Because the actual writing of the log gets differed, there's a chance that log messages might never make it to disk and get lost, if Mule were to crash before the buffers are flushed.
------------------------------------------------------------------------------------------------------------------ So Correct answer is: Asynchronous logging can improve Mule event processing throughput while also reducing the processing time for each Mule event

NEW QUESTION # 26
A manufacturing company is planning to deploy Mule applications to its own Azure Kubernetes Service infrastructure.
The organization wants to make the Mule applications more available and robust by deploying each Mule application to an isolated Mule runtime in a Docker container while managing all the Mule applications from the MuleSoft-hosted control plane.
What is the most idiomatic (used for its intended purpose) choice of runtime plane to meet these organizational requirements?

• A. Anypoint Service Mesh
• B. Anypoint Runtime Fabric
• C. CloudHub
• D. Anypoint Platform Private Cloud Edition

Answer: B

NEW QUESTION # 27
An organization has several APIs that accept JSON data over HTTP POST. The APIs are all publicly available and are associated with several mobile applications and web applications. The organization does NOT want to use any authentication or compliance policies for these APIs, but at the same time, is worried that some bad actor could send payloads that could somehow compromise the applications or servers running the API implementations. What out-of-the-box Anypoint Platform policy can address exposure to this threat?

• A. Apply a Header injection and removal policy that detects the malicious data before it is used
• B. Shut out bad actors by using HTTPS mutual authentication for all API invocations
• C. Apply a JSON threat protection policy to all APIs to detect potential threat vectors
• D. Apply an IP blacklist policy to all APIs; the blacklist will Include all bad actors

Answer: C

Explanation:
Explanation
We need to note few things about the scenario which will help us in reaching the correct solution.
Point 1 : The APIs are all publicly available and are associated with several mobile applications and web applications. This means Apply an IP blacklist policy is not viable option. as blacklisting IPs is limited to partial web traffic. It can't be useful for traffic from mobile application Point 2 : The organization does NOT want to use any authentication or compliance policies for these APIs.
This means we can not apply HTTPS mutual authentication scheme.
Header injection or removal will not help the purpose.
By its nature, JSON is vulnerable to JavaScript injection. When you parse the JSON object, the malicious code inflicts its damages. An inordinate increase in the size and depth of the JSON payload can indicate injection.
Applying the JSON threat protection policy can limit the size of your JSON payload and thwart recursive additions to the JSON hierarchy.
Hence correct answer is Apply a JSON threat protection policy to all APIs to detect potential threat vectors

NEW QUESTION # 28
An organization has deployed runtime fabric on an eight note cluster with performance profile. An API uses and non persistent object store for maintaining some of its state data. What will be the impact to the stale data if server crashes?

• A. State data is preserved as long as more than one more is unaffected by the crash
• B. State data is rolled back to a previously saved version
• C. State data is preserved
• D. State data is lost

Answer: A

NEW QUESTION # 29
What aspects of a CI/CD pipeline for Mule applications can be automated using MuleSoft-provided Maven plugins?

• A. Compile, package, unit test, deploy, create associated API instances in API Manager
• B. Compile, package, unit test, validate unit test coverage, deploy
• C. Compile, package, unit test, deploy, integration test (Incorrect)
• D. Import from API designer, compile, package, unit test, deploy, publish to Anypoint Exchange

Answer: B

Explanation:
Explanation
Correct answer is "Compile, package, unit test, validate unit test coverage, deploy" Explanation : Anypoint Platform supports continuous integration and continuous delivery using industry standard tools Mule Maven Plugin The Mule Maven plugin can automate building, packaging and deployment of Mule applications from source projects Using the Mule Maven plugin, you can automate your Mule application deployment to CloudHub, to Anypoint Runtime Fabric, or on-premises, using any of the following deployment strategies * CloudHub deployment * Runtime Fabric deployment * Runtime Manager REST API deployment * Runtime Manager agent deployment MUnit Maven Plugin The MUnit Maven plugin can automate test execution, and ties in with the Mule Maven plugin. It provides a full suite of integration and unit test capabilities, and is fully integrated with Maven and Surefire for integration with your continuous deployment environment. Since MUnit 2.x, the coverage report goal is integrated with the maven reporting section. Coverage Reports are generated during Maven's site lifecycle, during the coverage-report goal. One of the features of MUnit Coverage is to fail the build if a certain coverage level is not reached. MUnit is not used for integration testing Also publishing to Anypoint Exchange or to create associated API instances in API Manager is not a part of CICD pipeline which can ne achieved using mulesoft provided maven plugin Explanation Architecture mentioned in the question can be diagrammatically put as below. Persistent Object Store is the correct answer .
* Mule Object Stores: An object store is a facility for storing objects in or across Mule applications. Mule uses object stores to persist data for eventual retrieval.
Mule provides two types of object stores:
1) In-memory store - stores objects in local Mule runtime memory. Objects are lost on shutdown of the Mule runtime. So we cant use in memory store in our scenario as we want to share watermark within all cloudhub workers
2) Persistent store - Mule persists data when an object store is explicitly configured to be persistent. Hence this watermark will be available even any of the worker goes down Diagram Description automatically generated

NEW QUESTION # 30
An organization has decided on a cloud migration strategy to minimize the organization's own IT resources.
Currently the organization has all of its new applications running on its own premises and uses an on-premises load balancer that exposes all APIs under the base URL (https://api.rutujar.com).

NEW QUESTION # 33
A travel company wants to publish a well-defined booking service API to be shared with its business partners.
These business partners have agreed to ONLY consume SOAP services and they want to get the service contracts in an easily consumable way before they start any development. The travel company will publish the initial design documents to Anypoint Exchange, then share those documents with the business partners. When using an API-led approach, what is the first design document the travel company should deliver to its business partners?

• A. Create an OAS API specification in Design Center
• B. Create a RAML API specification using any text editor
• C. Create a SOAP API specification in Design Center
• D. Create a WSDL specification using any XML editor

Answer: D

Explanation:
Explanation
SOAP API specifications are provided as WSDL. Design center doesn't provide the functionality to create WSDL file. Hence WSDL needs to be created using XML editor

NEW QUESTION # 34
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?

• A. Create SOAP API specification using Design Center
• B. Create WSDL specification using text editor
• C. Create RAML specification using Design Center
• D. Create WSDL specification using Design Center

Answer: B

Explanation:
Explanation
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.

NEW QUESTION # 39
An organization is implementing a Quote of the Day API that caches today's quote. What scenario can use the CloudHub Object Store connector to persist the cache's state?

• A. When there are three CloudHub deployments of the API implementation to three separate CloudHub regions that must share the cache state.
• B. When there is one deployment of the API implementation to CloudHub and another one to customer hosted mule runtime that must share the cache state.
• C. When there is one CloudHub deployment of the API implementation to three workers that must share the cache state.
• D. When there are two CloudHub deployments of the API implementation by two Anypoint Platform business groups to the same CloudHub region that must share the cache state.

Answer: C

Explanation:
Explanation
Object Store Connector is a Mule component that allows for simple key-value storage. Although it can serve a wide variety of use cases, it is mainly design for: - Storing synchronization information, such as watermarks. - Storing temporal information such as access tokens. - Storing user information. Additionally, Mule Runtime uses Object Stores to support some of its own components, for example: - The Cache module uses an Object Store to maintain all of the cached data. - The OAuth module (and every OAuth enabled connector) uses Object Stores to store the access and refresh tokens. Object Store data is in the same region as the worker where the app is initially deployed. For example, if you deploy to the Singapore region, the object store persists in the Singapore region. MuleSoft Reference : https://docs.mulesoft.com/object-store-connector/1.1/ Data can be shared between different instances of the Mule application. This is not recommended for Inter Mule app communication. Coming to the question, object store cannot be used to share cached data if it is deployed as separate Mule applications or deployed under separate Business Groups. Hence correct answer is When there is one CloudHub deployment of the API implementation to three workers that must share the cache state.

NEW QUESTION # 40
As a part of project requirement, client will send a stream of data to mule application. Payload size can vary between 10mb to 5GB. Mule application is required to transform the data and send across multiple sftp servers. Due to the cost cuttings in the organization, mule application can only be allocated one worker with size of 0.2 vCore.
As an integration architect , which streaming strategy you would suggest to handle this scenario?

• A. In-memory repeatable stream
• B. In-memory non repeatable stream
• C. File based non-repeatable stream
• D. File based repeatable storage

Answer: D

Explanation:
Explanation
As the question says that data needs to be sent across multiple sftp serves , we cannot use non-repeatable streams. The non-repeatable strategy disables repeatable streams, which enables you to read an input stream only once.
You cant use in memory storage because with 0.2 vcore you will get only 1 GB of heap memory. Hence application will error out for file more than 1 GB.
Hence the correct option is file base repeatable stream
