問題3

Refer to the exhibit. An organization is running a Mule standalone runtime and has configured Active Directory as the Anypoint Platform external Identity Provider. The organization does not have budget for other system components.

What policy should be applied to all instances of APIs in the organization to most effecuvelyKestrict access to a specific group of internal users?

A. Apply a client ID enforcement policy; the specific group of users will configure their client applications to use their specific client credentials

B. Apply an OAuth 2.0 access token enforcement policy; the internal Active Directory will be configured as the OAuth server

C. Apply a basic authentication - LDAP policy; the internal Active Directory will be configured as the LDAP source for authenticating users

D. Apply an IP whitelist policy; only the specific users' workstations will be in the whitelist

問題4

A set of tests must be performed prior to deploying API implementations to a staging environment. Due to data security and access restrictions, untested APIs cannot be granted access to the backend systems, so instead mocked data must be used for these tests. The amount of available mocked data and its contents is sufficient to entirely test the API implementations with no active connections to the backend systems. What type of tests should be used to incorporate this mocked data?

A. Integration tests

B. Functional tests (Blackbox)

C. Unit tests (Whitebox)

D. Performance tests

問題5

Refer to the exhibit.

What is the best way to decompose one end-to-end business process into a collaboration of Experience, Process, and System APIs?
A) Handle customizations for the end-user application at the Process API level rather than the Experience API level

B) Allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs

C) Always use a tiered approach by creating exactly one API for each of the 3 layers (Experience, Process and System APIs)

D) Use a Process API to orchestrate calls to multiple System APIs, but NOT to other Process APIs

A. Option B

B. Option D

C. Option C

D. Option A

問題6

What best describes the Fully Qualified Domain Names (FQDNs), also known as DNS entries, created when a Mule application is deployed to the CloudHub Shared Worker Cloud?

A. A fixed number of FQDNs are created, IRRESPECTIVE of the environment and VPC design

B. The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region

C. The FQDNs are determined by both the application name and the Anypoint Platform organization

D. The FQDNs are determined by the application name, but can be modified by an administrator after deployment

正確答案: B

問題7

An API client calls one method from an existing API implementation. The API implementation is later updated. What change to the API implementation would require the API client's invocation logic to also be updated?

A. When the data type of the response is changed for the method called by the API client

B. When a new method is added to the resource used by the API client

C. When a new required field is added to the method called by the API client

D. When a child method is added to the method called by the API client

問題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. Drive consumption as much as production of assets; this enables developers to discover and reuse assets from other projects and encourages standardization

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. 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

正確答案: B

問題9

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. Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries

B. 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

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 100 ms; that leaves 400 ms for the other two downstream APIs to complete
