NEW QUESTION # 37
A Mule application is running on a customer-hosted Mule runtime in an organization's network. The Mule application acts as a producer of asynchronous Mule events. Each Mule event must be broadcast to all interested external consumers outside the Mule application. The Mule events should be published in a way that is guaranteed in normal situations and also minimizes duplicate delivery in less frequent failure scenarios.
The organizational firewall is configured to only allow outbound traffic on ports 80 and 443. Some external event consumers are within the organizational network, while others are located outside the firewall.
What Anypoint Platform service is most idiomatic (used for its intended purpose) for publishing these Mule events to all external consumers while addressing the desired reliability goals?
- A. Anypoint MQ
- B. Anypoint Exchange
- C. CloudHub VM queues
- D. CloudHub Shared Load Balancer
Answer: A
Explanation:
Explanation
Set the Anypoint MQ connector operation to publish or consume messages, or to accept (ACK) or not accept (NACK) a message.

NEW QUESTION # 41
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 50 ms; this times out more invocations of that API but gives additional room for retries
- 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
Answer: A
Explanation:
Explanation
Before we answer this question , we need to understand what median (50th percentile) and 80th percentile means. If the 50th percentile (median) of a response time is 500ms that means that 50% of my transactions are either as fast or faster than 500ms.
If the 90th percentile of the same transaction is at 1000ms it means that 90% are as fast or faster and only 10% are slower. Now as per upstream SLA , 99th percentile is 800 ms which means 99% of the incoming requests should have response time less than or equal to 800 ms. But as per one of the backend API , their 95th percentile is 1000 ms which means that backend API will take 1000 ms or less than that for 95% of. requests.
As there are three API invocation from upstream API , we can not conclude a timeout that can be set to meet the desired SLA as backend SLA's do not support it.
Let see why other answers are not correct.
1) Do not set a timeout --> This can potentially violate SLA's of upstream API
2) Set a timeout of 100 ms; ---> This will not work as backend API has 100 ms as median meaning only 50% requests will be answered in this time and we will get timeout for 50% of the requests. Important thing to note here is, All APIs need to be executed sequentially, so if you get timeout in first API, there is no use of going to second and third API. As a service provider you wouldn't want to keep 50% of your consumers dissatisfied. So not the best option to go with.
*To quote an example: Let's assume you have built an API to update customer contact details.
- First API is fetching customer number based on login credentials
- Second API is fetching Info in 1 table and returning unique key
- Third API, using unique key provided in second API as primary key, updating remaining details
* Now consider, if API times out in first API and can't fetch customer number, in this case, it's useless to call API 2 and 3 and that is why question mentions specifically that all APIs need to be executed sequentially.
3) Set a timeout of 50 ms --> Again not possible due to the same reason as above Hence correct answer is 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
NEW QUESTION # 42
How are the API implementation , API client, and API consumer combined to invoke and process an API ?
- A. The API consumer creates an API client which sends API invocations to an API such that they are processed by an API implementation
- B. The API client creates an API consumer which sends API invocations to an API such that they are processed by API implementation
- C. The API consumer creates an API implementation , which receives API invocations from an API such that they are processed for an API client
- D. An API client creates an API consumer, which receives API invocation from an API such that they are processed for an API implementation
Answer: D
Explanation:
Explanation
The API consumer creates an API client which sends API invocations to an API such that they are processed by an API implementation This is based on below definitions API client * An application component * that accesses a service * by invoking an API of that service - by definition of the term API over HTTP API consumer * A business role, which is often assigned to an individual * that develops API clients, i.e., performs the activities necessary for enabling an API client to invoke APIs API implementation * An application component * that implements the functionality

Which Mulesoft feature helps users to delegate their access without sharing sensitive credentials or giving full control of accounts to 3rd parties?
- A. Secure Scheme
- B. client id enforcement policy
- C. Connected apps
- D. Certificates
Answer: C
Explanation:
Explanation
Connected Apps
The Connected Apps feature provides a framework that enables an external application to integrate with Anypoint Platform using APIs through OAuth 2.0 and OpenID Connect. Connected apps help users delegate their access without sharing sensitive credentials or giving full control of their accounts to third parties.
Actions taken by connected apps are audited, and users can also revoke access at any time. Note that some products do not currently include client IDs in this release of the Connected Apps feature. The Connected Apps feature enables you to use secure authentication protocols and control an app's access to user data.
Additionally, end users can authorize the app to access their Anypoint Platform data.

NEW QUESTION # 48
Organization wants to achieve high availability goal for Mule applications in customer hosted runtime plane.
Due to the complexity involved, data cannot be shared among of different instances of same Mule application.
What option best suits to this requirement considering high availability is very much critical to the organization?
- A. Use third party product to implement load balancer
- B. High availability can be achieved only in CloudHub
- C. Use persistent object store
- D. The cluster can be configured
Answer: A
Explanation:
Explanation
High availability is about up-time of your application
A) High availability can be achieved only in CloudHub isn't correct statement. It can be achieved in customer hosted runtime planes as well B) An object store is a facility for storing objects in or across Mule applications. Mule runtime engine (Mule) uses object stores to persist data for eventual retrieval. It can be used for disaster recovery but not for High Availability. Using object store can't guarantee that all instances won't go down at once. So not an appropriate choice.
