An organization is deploying their new implementation of the OrderStatus System API to
multiple workers in CloudHub. This API fronts the organization's on-premises Order
Management System, which is accessed by the API implementation over an IPsec tunnel.
What type of error typically does NOT result in a service outage of the OrderStatus System
API?
A.
A CloudHub worker fails with an out-of-memory exception
B.
API Manager has an extended outage during the initial deployment of the API
implementation
C.
The AWS region goes offline with a major network failure to the relevant AWS data centers
D.
The Order Management System is Inaccessible due to a network outage in the
organization's on-premises data center
A CloudHub worker fails with an out-of-memory exception
Explanation: Explanation
Correct Answer: A CloudHub worker fails with an out-of-memory exception.
*****************************************
>> An AWS Region itself going down will definitely result in an outage as it does not matter
how many workers are assigned to the Mule App as all of those in that region will go down.
This is a complete downtime and outage.
>> Extended outage of API manager during initial deployment of API implementation will of
course cause issues in proper application startup itself as the API Autodiscovery might fail
or API policy templates and polices may not be downloaded to embed at the time of
applicaiton startup etc... there are many reasons that could cause issues.
>> A network outage onpremises would of course cause the Order Management System
not accessible and it does not matter how many workers are assigned to the app they all
will fail and cause outage for sure.
The only option that does NOT result in a service outage is if a cloudhub worker fails with
an out-of-memory exception. Even if a worker fails and goes down, there are still other
workers to handle the requests and keep the API UP and Running. So, this is the right
answer.
A company has started to create an application network and is now planning to implement a Center for Enablement (C4E) organizational model. What key factor would lead the company to decide upon a federated rather than a centralized C4E?
A.
When there are a large number of existing common assets shared by development teams
B.
When various teams responsible for creating APIs are new to integration and hence need extensive training
C.
When development is already organized into several independent initiatives or groups
D.
When the majority of the applications in the application network are cloud based
When development is already organized into several independent initiatives or groups
Explanation: Explanation
Correct Answer: When development is already organized into several independent
initiatives or groups
*****************************************
>> It would require lot of process effort in an organization to have a single C4E team
coordinating with multiple already organized development teams which are into several
independent initiatives. A single C4E works well with different teams having at least a
common initiative. So, in this scenario, federated C4E works well instead of centralized
C4E.
A TemperatureSensors API instance is defined in API Manager in the PROD environment
of the CAR_FACTORY business group. An AcmelemperatureSensors Mule
application implements this API instance and is deployed from Runtime Manager to the
PROD environment of the CAR_FACTORY business group. A policy that requires a valid
client ID and client secret is applied in API Manager to the API instance.
Where can an API consumer obtain a valid client ID and client secret to call the
AcmeTemperatureSensors Mule application?
A. In secrets manager, request access to the Shared Secret static username/password
B. In API Manager, from the PROD environment of the CAR_FACTORY business group
C. In access management, from the PROD environment of the CAR_FACTORY business group
D. In Anypoint Exchange, from an API client application that has been approved for the TemperatureSensors API instance
Explanation:
When an API policy requiring a client ID and client secret is applied to an
API instance in API Manager, API consumers must obtain these credentials through a
registered client application. Here’s how it works:
Which statement is true about Spike Control policy and Rate Limiting policy?
A. All requests are rejected after the limit is reached in Rate Limiting policy, whereas the requests are queued in Spike Control policy after the limit is reached
B. In a clustered environment, the Rate Limiting.and Spike Control policies are applied to each node in the cluster
C. To protect Experience APIs by limiting resource consumption, Rate Limiting policy must be applied
D. In order to apply Rate Limiting and Spike Control policies, a contract to bind client application and API is needed for both
A European company has customers all across Europe, and the IT department is migrating from an older platform to MuleSoft. The main requirements are that the new platform should allow redeployments with zero downtime and deployment of applications to multiple runtime versions, provide security and speed, and utilize Anypoint MQ as the message service. Which runtime plane should the company select based on the requirements without additional network configuration?
A. Runtime Fabric on VMs / Bare Metal for the runtime plane
B. Customer-hosted runtime plane
C. MuleSoft-hosted runtime plane (CloudHub)
D. Anypoint Runtime Fabric on Self-Managed Kubernetes for the runtime plane
Explanation:
For a European company with requirements such as zero-downtime
redeployment, deployment to multiple runtime versions, secure and fast
performance, and the use of Anypoint MQ without additional network configuration,
CloudHub is the best choice for the following reasons:
What do the API invocation metrics provided by Anypoint Platform provide?
A.
ROI metrics from APIs that can be directly shared with business users
B.
Measurements of the effectiveness of the application network based on the level of reuse
C.
Data on past API invocations to help identify anomalies and usage patterns across various APIs
D.
Proactive identification of likely future policy violations that exceed a given threat
threshold
Data on past API invocations to help identify anomalies and usage patterns across various APIs
Explanation: Explanation
Correct Answer: Data on past API invocations to help identify anomalies and usage
patterns across various APIs
*****************************************
API Invocation metrics provided by Anypoint Platform:
>> Does NOT provide any Return Of Investment (ROI) related information. So the option
suggesting it is OUT.
>> Does NOT provide any information w.r.t how APIs are reused, whether there is effective
usage of APIs or not etc...
>> Does NOT prodive any prediction information as such to help us proactively identify any
future policy violations.
So, the kind of data/information we can get from such metrics is on past API invocations to
help identify anomalies and usage patterns across various APIs.

A Platinum customer uses the U.S. control plane and deploys applications to CloudHub in Singapore with a default log configuration. The compliance officer asks where the logs and monitoring data reside?
A. Logs are held in: Singapore and monitoring data is held in the United States
B. Logs and monitoring data are held in the United States
C. Logs are held in the United States and monitoring data is held in Singapore
D. Logs and monitoring data are held in Singapore
Explanation:
For applications deployed on CloudHub in a foreign region (e.g., Singapore),
MuleSoft handles log and monitoring data in the region where the control plane
resides. This data storage policy is standard for CloudHub deployments to maintain
centralized log and monitoring data.
Which statement is true about identity management and client management on Anypoint Platform?
A. If an external identity provider is configured, the SAML 2.0 bearer tokens issued by the identity provider cannot be used for invocations of the Anypoint Platform web APIs
B. If an external client provider is configured, it must be configured at the Anypoint Platform organization level and cannot be assigned to individual business groups and environments
C. Anypoint Platform supports configuring one external identity provider
D. Both client management and identity management require an identity provider
Explanation:
Anypoint Platform allows organizations to integrate one external identity
provider (IdP) for identity and access management (IAM), supporting SSO and centralized
user authentication.
