質問 2：
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

質問 3：
Say, there is a legacy CRM system called CRM-Z which is offering below functions:
1. Customer creation
2. Amend details of an existing customer
3. Retrieve details of a customer
4. Suspend a customer
A. Implement a system API named customerManagement which has all the functionalities wrapped in it as various operations/resources
B. Implement different system APIs named createCustomer, amendCustomer, retrieveCustomer and suspendCustomer as they are modular and has seperation of concerns
C. Implement different system APIs named createCustomerInCRMZ, amendCustomerInCRMZ, retrieveCustomerFromCRMZ and suspendCustomerInCRMZ as they are modular and has seperation of concerns
正解：B

質問 4：
An organization has implemented a Customer Address API to retrieve customer address information. This API has been deployed to multiple environments and has been configured to enforce client IDs everywhere.
A developer is writing a client application to allow a user to update their address. The developer has found the Customer Address API in Anypoint Exchange and wants to use it in their client application.
What step of gaining access to the API can be performed automatically by Anypoint Platform?
A. Approve the client application request for the chosen SLA tier
B. Request access to the appropriate API Instances deployed to multiple environments using the client application's credentials
C. Create a new application in Anypoint Exchange for requesting access to the API
D. Modify the client application to call the API using the client application's credentials
正解：A

質問 5：
What is a key requirement when using an external Identity Provider for Client Management in Anypoint Platform?
A. Single sign-on is required to sign in to Anypoint Platform
B. To invoke OAuth 2.0-protected APIs managed by Anypoint Platform, API clients must submit access tokens issued by that same Identity Provider
C. APIs managed by Anypoint Platform must be protected by SAML 2.0 policies
D. The application network must include System APIs that interact with the Identity Provider

質問 6：
What is most likely NOT a characteristic of an integration test for a REST API implementation?
A. The test runs immediately after the Mule application has been compiled and packaged
B. The test needs all source and/or target systems configured and accessible
C. The test is triggered by an external HTTP request
D. The test prepares a known request payload and validates the response payload
正解：A

質問 7：
A new upstream API Is being designed to offer an SLA of 500 ms median and 800 ms maximum (99th percentile) response time. The corresponding API implementation needs to sequentially invoke 3 downstream APIs of very similar complexity.
The first of these downstream APIs offers the following SLA for its response time: median: 100 ms, 80th percentile: 500 ms, 95th percentile: 1000 ms.
If possible, how can a timeout be set in the upstream API for the invocation of the first downstream API to meet the new upstream API's desired SLA?
A. No timeout is possible to meet the upstream API's desired SLA; a different SLA must be negotiated with the first downstream API or invoke an alternative API
B. Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete
C. Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds
D. Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries
正解：B

質問 8：
What is the main change to the IT operating model that MuleSoft recommends to organizations to improve innovation and clock speed?
A. Implement SOA for reusable APIs to focus on production over consumption; this standardizes on XML and WSDL formats to speed up decision making
B. Create a lean and agile organization that makes many small decisions everyday; this speeds up decision making and enables each line of business to take ownership of its projects
C. Expose assets using a Master Data Management (MDM) system; this standardizes projects and enables developers to quickly discover and reuse assets from other projects
D. Drive consumption as much as production of assets; this enables developers to discover and reuse assets from other projects and encourages standardization
