A System API is designed to retrieve data from a backend system that has scalability challenges. What API policy can best safeguard the backend system?


A.

IPwhitelist


B.

SLA-based rate limiting


C.

Auth 2 token enforcement


D.

Client ID enforcement





B.   

SLA-based rate limiting



Explanation: Explanation
Correct Answer: SLA-based rate limiting
*****************************************
>> Client Id enforement policy is a "Compliance" related NFR and does not help in
maintaining the "Quality of Service (QoS)". It CANNOT and NOT meant for protecting the
backend systems from scalability challenges.
>> IP Whitelisting and OAuth 2.0 token enforcement are "Security" related NFRs and again
does not help in maintaining the "Quality of Service (QoS)". They CANNOT and are NOT
meant for protecting the backend systems from scalability challenges.
Rate Limiting, Rate Limiting-SLA, Throttling, Spike Control are the policies that are "Quality
of Service (QOS)" related NFRs and are meant to help in protecting the backend systems
from getting overloaded.

The asset version 2.0.0 of the Order API is successfully published in Exchange and configured in API Manager with the Autodiscovery API ID correctly linked to the API implementation, A new GET method is added to the existing API specification, and after updates, the asset version of the Order API is 2.0.1. What happens to the Autodiscovery API ID when the new asset version is updated in API Manager?


A. The API ID changes, but no changes are needed to the API implementation for the new asset version in the API Autediscovery global element because the API ID is automatically updated


B. The APL ID changes, so the API implementation must be updated with the latest API ID for the new asset version in the API Autodiscovery global element


C. The APLID does not change, so no changes to the APT implementation are needed for the new asset version in the API Autodiscovery global element


D. The APL ID does not change, but the API implementation must be updated in the AP] Autodiscovery global element to indicate the new asset version 2.0.4





C.   The APLID does not change, so no changes to the APT implementation are needed for the new asset version in the API Autodiscovery global element

Explanation:
Understanding API Autodiscovery in MuleSoft:
Effect of Asset Version Update on API Autodiscovery:

A company has created a successful enterprise data model (EDM). The company is
committed to building an application network by adopting modern APIs as a core enabler of
the company's IT operating model. At what API tiers (experience, process, system) should
the company require reusing the EDM when designing modern API data models?


A.

At the experience and process tiers


B.

At the experience and system tiers


C.

At the process and system tiers


D.

At the experience, process, and system tiers





C.   

At the process and system tiers



Explanation: Explanation Correct Answer: At the process and system tiers
*****************************************
>> Experience Layer APIs are modeled and designed exclusively for the end user's
experience. So, the data models of experience layer vary based on the nature and type of
such API consumer. For example, Mobile consumers will need light-weight data models to
transfer with ease on the wire, where as web-based consumers will need detailed data
models to render most of the info on web pages, so on. So, enterprise data models fit for
the purpose of canonical models but not of good use for experience APIs.
>> That is why, EDMs should be used extensively in process and system tiers but NOT in
experience tier.

An Order API triggers a sequence of other API calls to look up details of an order's items in a back-end inventory database. The Order API calls the OrderItems process API, which calls the Inventory system API. The Inventory system API performs database operations in the back-end inventory database.
The network connection between the Inventory system API and the database is known to be unreliable and hang at unpredictable times.
Where should a two-second timeout be configured in the API processing sequence so that the Order API never waits more than two seconds for a response from the Orderltems process API?


A. In the Orderltems process API implementation


B. In the Order API implementation


C. In the Inventory system API implementation


D. In the inventory database





A.   In the Orderltems process API implementation

An enterprise is embarking on the API-led digital transformation journey, and the central IT team has started to define System APIs. Currently there is no Enterprise Data Model being defined within the enterprise, and the definition of a clean Bounded Context Data Model requires too much effort. According to MuleSoft's recommended guidelines, how should the System API data model be defined?


A. If there are misspellings of the data fields in the back-end system, Systerm APIs should not correct it, and expose it as-is to mirror the back-end systems


B. The data model of the System APIs should make use of data types that approximately mirror those from the back-end systems


C. The data model should define its own naming convention, and not follow the same naming as the back-end systems


D. The System APIs should expose all back-end system fields





B.   The data model of the System APIs should make use of data types that approximately mirror those from the back-end systems

Explanation: When defining data models for System APIs without an established Enterprise Data Model, MuleSoft recommends mirroring the back-end systems' data types to achieve quick and effective integration without adding complexity. This approach has several benefits:

  • Alignment with Backend Systems:
  • Flexibility for Future Enhancements:
  • Explanation of Incorrect Options:

A company deployed an API to a single worker/replica in the shared cloud in the U.S. West Region. What happens when the Availability Zone experiences an outage?


A. CloudHub will auto-redeploy the APL in the U.S. East Region


B. The APT will be unavailable until the availability comes back online, at which time the worker/replica will be auto-restarted


C. CloudHub will auto-redeploy the API in another Availability Zone in the U.S. West Region


D. The Anypoint Platform admin is alerted when the AP] is experiencing an outage and needs the trigger the CI/CD pipeline to redeploy to the US. East Region





B.   The APT will be unavailable until the availability comes back online, at which time the worker/replica will be auto-restarted

Explanation:
In a CloudHub deployment with a single worker/replica located in a specific Availability Zone (AZ), if an AZ experiences an outage, here’s what happens:
Worker Availability: Since the application is deployed in a single AZ, CloudHub does not automatically redeploy the application in a different zone or region during an outage. Thus, if the current AZ is unavailable, the application will be offline.
Auto-Restart upon AZ Recovery: Once the affected AZ is back online, CloudHub will auto-restart the worker in the same AZ without manual intervention. This ensures that as soon as the AZ is functional, the application resumes automatically.
