MuleSoft Certified Developer - Level 2 (Mule 4) 認定 MCD-Level-2 試験問題:

1. The flow is invoicing a target API. The API's protocol is HTTPS. The TLS configuration in the HTTP Request Configuration global element is set to None. A web client submits a request to
http:localhost:8081/vehicles.

If the certificate of the target API is signed by a certificate authority (CA), what is true about the HTTP Request operation when the flow executes?

A) The HTTP Request operation will always succeed regardless of the CA
B) The HTTP Request operation will succeed if the CA'S certificate is present in the JRE's default keystore
C) The HTTP Request operation will always fail regardless of the CA
D) The HTTP Request operation will succeed if the CA's certificate is present in the JRE's default truststore.

2. A Mule API receives a JSON payload and updates the target system with the payload. The developer uses JSON schemas to ensure the data is valid.
How can the data be validation before posting to the target system?

A) Add the JSON module dependency and add the validate-schema operation in the flow, configured to reference the schema
B) Use a DataWeave 2.09 transform operation, and at the log of the DataWeave script, add:
%dw 2.0
Import.json-moduls
C) Using the DataWeave if Else condition test the values of the payload against the examples included in the schema
D) Apply the JSON Schema policy in API Manager and reference the correct schema in the policy configuration

3. A Mule implementation uses a HTTP Request within an Unit Successful scope to connect to an API.
How should a permanent error response like HTTP:UNAUTHORIZED be handle inside Until Successful to reduce latency?

A) Put the HTTP Request inside a try scope in Unit Successful.
In the error handler, use On Error Continue to catch permanent errors like HTTP UNAUTHORIZED.
B) In Until Successful configuration, set the retry count to 1 for error type HTTP: UNAUTHORIZED.
C) Put the HTTP Request inside a try scope in Unit Successful.
In the error handler, use On Error Propagate to catch permanent errors like HTTP UNAUTHORIZED.
D) Configure retrying until a MULERETRY_EXHAUSTED error is raised or the API responds back with a successful response.

4. A Mule application contain two policies Policy A and Policy A has order1, and Policy B has order 2. Policy A Policy B, and a flow are defined by he configuration below.

When a HTTP request arrives at the Mule application's endpoint, what will be the execution order?

A) A1, B1, F1, B2, A2
B) B1, A1, F1, A2, B2
C) F1, B1, A1, A2, B2
D) F1, A1, B1, B2, A2

5. An API has been developed and deployed to CloudHub Among the policies applied to this API is an allowlist of IP addresses. A developer wants to run a test in Anypoint Studio and does not want any policies applied because their workstation is not included in the allowlist.
What must the developer do in order to run this test locally without the policies applied?

A) Create a properties file specifically for local development and set the API instance ID to a value that is not used in API Manager
B) Deactivate the API in API Manager so the Autodiscovery element will not find the application when it runs in Studio
C) Run the test as-s, with no changes because the Studio runtime will not attempt to connect to API Manager
D) Pass in the runtime parameter ''-Danpow.platform.gatekeeper=disabled''
