NEW QUESTION # 22
A Mule application exposes an HTTPS endpoint and is deployed to the CloudHub Shared Worker Cloud. All traffic to that Mule application must stay inside the AWS VPC.
To what TCP port do API invocations to that Mule application need to be sent?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
Correct answer: 8082
*****************************************
>> 8091 and 8092 ports are to be used when keeping your HTTP and HTTPS app private to the LOCAL VPC respectively.
>> Above TWO ports are not for Shared AWS VPC/ Shared Worker Cloud.
>> 8081 is to be used when exposing your HTTP endpoint app to the internet through Shared LB
>> 8082 is to be used when exposing your HTTPS endpoint app to the internet through Shared LB So, API invocations should be sent to port 8082 when calling this HTTPS based app.

NEW QUESTION # 26
What Mule application deployment scenario requires using Anypoint Platform Private Cloud Edition or Anypoint Platform for Pivotal Cloud Foundry?
- A. When it Is required to make ALL applications highly available across multiple data centers
- B. When it is required that ALL APIs are private and NOT exposed to the public cloud
- C. When regulatory requirements mandate on-premises processing of EVERY data item, including meta-data
- D. When ALL backend systems in the application network are deployed in the organization's intranet
Answer: C
Explanation:
When regulatory requirements mandate on-premises processing of EVERY data item, including meta-data.
*****************************************
We need NOT require to use Anypoint Platform PCE or PCF for the below. So these options are OUT.
>> We can make ALL applications highly available across multiple data centers using CloudHub too.
>> We can use Anypoint VPN and tunneling from CloudHub to connect to ALL backend systems in the application network that are deployed in the organization's intranet.
>> We can use Anypoint VPC and Firewall Rules to make ALL APIs private and NOT exposed to the public cloud.
Only valid reason in the given options that requires to use Anypoint Platform PCE/ PCF is - When regulatory requirements mandate on-premises processing of EVERY data item, including meta-data.
NEW QUESTION # 27
What CANNOT be effectively enforced using an API policy in Anypoint Platform?
- A. Maintaining tamper-proof credentials between APIs
- B. Guarding against Denial of Service attacks
- C. Backend system overloading
- D. Logging HTTP requests and responses
Answer: B
Explanation:
Guarding against Denial of Service attacks
*****************************************
>> Backend system overloading can be handled by enforcing "Spike Control Policy"
>> Logging HTTP requests and responses can be done by enforcing "Message Logging Policy"
>> Credentials can be tamper-proofed using "Security" and "Compliance" Policies However, unfortunately, there is no proper way currently on Anypoint Platform to guard against DOS attacks.

The API endpoint does NOT change in the new version.
How should the developer of an API client respond to this change?
- A. The update should be identified as a project risk and full regression testing of the functionality that uses this API should be run
- B. The API client code ONLY needs to be changed if it needs to take advantage of new features
- C. The API producer should be contacted to understand the change to existing functionality
- D. The API producer should be requested to run the old version in parallel with the new one
Answer: B
NEW QUESTION # 29

NEW QUESTION # 30
How are an API implementation, API client, and API consumer combined to invoke and process an API?
- A. The ApI client creates an API consumer, which sends API invocations to an API such that they are processed by an API implementation
- B. The API consumer creates an API implementation, which receives API invocations from an API such that they are processed for an API client
- C. The ApI consumer creates an API client, which sends API invocations to an API such that they are processed by an API implementation
- D. The API client creates an API consumer, which receives API invocations from an API such that they are processed for an API implementation
Answer: C
Explanation:
The API consumer creates an API client, which sends API invocations to an API such that they are processed by an API implementation
*****************************************
Terminology:
>> API Client - It is a piece of code or program the is written to invoke an API
>> API Consumer - An owner/entity who owns the API Client. API Consumers write API clients.
>> API - The provider of the API functionality. Typically an API Instance on API Manager where they are managed and operated.
>> API Implementation - The actual piece of code written by API provider where the functionality of the API is implemented. Typically, these are Mule Applications running on Runtime Manager.
NEW QUESTION # 31
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. SLA-based rate limiting
- B. IPwhitelist
- C. Client ID enforcement
- D. Auth 2 token enforcement
Answer: A
Explanation:
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.

NEW QUESTION # 32
What condition requires using a CloudHub Dedicated Load Balancer?
- A. When API invocations across multiple CloudHub workers must be load balanced
- B. When server-side load-balanced TLS mutual authentication is required between API implementations and API clients
- C. When cross-region load balancing is required between separate deployments of the same Mule application
- D. When custom DNS names are required for API implementations deployed to customer-hosted Mule runtimes
Answer: B
Explanation:
When server-side load-balanced TLS mutual authentication is required between API implementations and API clients
*****************************************
Fact/ Memory Tip: Although there are many benefits of CloudHub Dedicated Load balancer, TWO important things that should come to ones mind for considering it are:
>> Having URL endpoints with Custom DNS names on CloudHub deployed apps
>> Configuring custom certificates for both HTTPS and Two-way (Mutual) authentication.
Coming to the options provided for this question:
>> We CANNOT use DLB to perform cross-region load balancing between separate deployments of the same Mule application.
>> We can have mapping rules to have more than one DLB URL pointing to same Mule app. But vicevera (More than one Mule app having same DLB URL) is NOT POSSIBLE
>> It is true that DLB helps to setup custom DNS names for Cloudhub deployed Mule apps but NOT true for apps deployed to Customer-hosted Mule Runtimes.
>> It is true to that we can load balance API invocations across multiple CloudHub workers using DLB but it is NOT A MUST. We can achieve the same (load balancing) using SLB (Shared Load Balancer) too. We DO NOT necessarily require DLB for achieve it.
So the only right option that fits the scenario and requires us to use DLB is when TLS mutual authentication is required between API implementations and API clients.
NEW QUESTION # 33

- B. When the API Implementation must write to a persistent Object Store
- C. When the API implementation must be deployed to a production AWS VPC using the Mule Maven plugin
- D. When the API implementation must be accessible within a subnet of a restricted customer-hosted network that does not allow public access
Answer: D
NEW QUESTION # 34
An organization is implementing a Quote of the Day API that caches today's quote.
- A. What scenario can use the GoudHub Object Store via the Object Store connector to persist the cache's state?
- B. When there are two CloudHub deployments of the API implementation by two Anypoint Platform business groups to the same CloudHub region that must share the cache state
- C. When there is one CloudHub deployment of the API implementation to three CloudHub workers that must share the cache state
- D. When there are three CloudHub deployments of the API implementation to three separate CloudHub regions that must share the cache state
- E. When there is one deployment of the API implementation to CloudHub and anottV deployment to a customer-hosted Mule runtime that must share the cache state
Answer: B
NEW QUESTION # 35
An API implementation is being designed that must invoke an Order API, which is known to repeatedly experience downtime.
For this reason, a fallback API is to be called when the Order API is unavailable.
What approach to designing the invocation of the fallback API provides the best resilience?
- A. Set an option in the HTTP Requester component that invokes the Order API to instead invoke a fallback API whenever an HTTP 4xx or 5xx response status code is returned from the Order API
- B. Search Anypoint Exchange for a suitable existing fallback API, and then implement invocations to this fallback API in addition to the Order API
- C. Redirect client requests through an HTTP 307 Temporary Redirect status code to the fallback API whenever the Order API is unavailable
- D. Create a separate entry for the Order API in API Manager, and then invoke this API as a fallback API if the primary Order API is unavailable
Answer: B
Explanation:
Search Anypoint exchange for a suitable existing fallback API, and then implement invocations to this fallback API in addition to the order API
*****************************************
>> It is not ideal and good approach, until unless there is a pre-approved agreement with the API clients that they will receive a HTTP 3xx temporary redirect status code and they have to implement fallback logic their side to call another API.
>> Creating separate entry of same Order API in API manager would just create an another instance of it on top of same API implementation. So, it does NO GOOD by using clone od same API as a fallback API.
Fallback API should be ideally a different API implementation that is not same as primary one.
>> There is NO option currently provided by Anypoint HTTP Connector that allows us to invoke a fallback API when we receive certain HTTP status codes in response.
The only statement TRUE in the given options is to Search Anypoint exchange for a suitable existing fallback API, and then implement invocations to this fallback API in addition to the order API.
NEW QUESTION # 36
When using CloudHub with the Shared Load Balancer, what is managed EXCLUSIVELY by the API implementation (the Mule application) and NOT by Anypoint Platform?
- A. The number of DNS entries allocated to the API implementation
- B. The SSL certificates used by the API implementation to expose HTTPS endpoints
- C. The assignment of each HTTP request to a particular CloudHub worker
- D. The logging configuration that enables log entries to be visible in Runtime Manager
Answer: D
NEW QUESTION # 37
An API implementation is updated. When must the RAML definition of the API also be updated?
- A. When the API implementation changes from interacting with a legacy backend system deployed on-premises to a modern, cloud-based (SaaS) system
- B. When the API implementation changes the structure of the request or response messages
- C. When the API implementation is migrated from an older to a newer version of the Mule runtime
- D. When the API implementation is optimized to improve its average response time
Answer: B
Explanation:
Correct answer: When the API implementation changes the structure of the request or response messages
*****************************************
>> RAML definition usually needs to be touched only when there are changes in the request/response schemas or in any traits on API.
>> It need not be modified for any internal changes in API implementation like performance tuning, backend system migrations etc..
NEW QUESTION # 38
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. The FQDNs are determined by the application name, but can be modified by an administrator after deployment
- B. The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region
- C. A fixed number of FQDNs are created, IRRESPECTIVE of the environment and VPC design
- D. The FQDNs are determined by both the application name and the Anypoint Platform organization
Answer: B
Explanation:
The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region
*****************************************
>> When deploying applications to Shared Worker Cloud, the FQDN are always determined by application name chosen.
>> It does NOT matter what region the app is being deployed to.
>> Although it is fact and true that the generated FQDN will have the region included in it (Ex:
exp-salesorder-api.au-s1.cloudhub.io), it does NOT mean that the same name can be used when deploying to another CloudHub region.
>> Application name should be universally unique irrespective of Region and Organization and solely determines the FQDN for Shared Load Balancers.
NEW QUESTION # 39
When using CloudHub with the Shared Load Balancer, what is managed EXCLUSIVELY by the API implementation (the Mule application) and NOT by Anypoint Platform?
- A. The number of DNS entries allocated to the API implementation
- B. The SSL certificates used by the API implementation to expose HTTPS endpoints
- C. The assignment of each HTTP request to a particular CloudHub worker
- D. The logging configuration that enables log entries to be visible in Runtime Manager
Answer: C
NEW QUESTION # 40
Traffic is routed through an API proxy to an API implementation. The API proxy is managed by API Manager and the API implementation is deployed to a CloudHub VPC using Runtime Manager. API policies have been applied to this API. In this deployment scenario, at what point are the API policies enforced on incoming API client requests?
- A. At both the API proxy and the API implementation
- B. At the API implementation
- C. At the API proxy
- D. At a MuleSoft-hosted load balancer
Answer: C
Explanation:
At the API proxy
*****************************************
>> API Policies can be enforced at two places in Mule platform.
>> One - As an Embedded Policy enforcement in the same Mule Runtime where API implementation is running.
>> Two - On an API Proxy sitting in front of the Mule Runtime where API implementation is running.
>> As the deployment scenario in the question has API Proxy involved, the policies will be enforced at the API Proxy.
NEW QUESTION # 41
What is true about API implementations when dealing with legal regulations that require all data processing to be performed within a certain jurisdiction (such as in the USA or the EU)?
- A. They must avoid using the Object Store as it depends on services deployed ONLY to the US East region
- B. They must ensure ALL data is encrypted both in transit and at rest
- C. They must use a Jurisdiction-local external messaging system such as Active MQ rather than Anypoint MQ
- D. They must te deployed to Anypoint Platform runtime planes that are managed by Anypoint Platform control planes, with both planes in the same Jurisdiction
Answer: D
Explanation:
They must be deployed to Anypoint Platform runtime planes that are managed by Anypoint Platform control planes, with both planes in the same Jurisdiction.
*****************************************
>> As per legal regulations, all data processing to be performed within a certain jurisdiction. Meaning, the data in USA should reside within USA and should not go out. Same way, the data in EU should reside within EU and should not go out.
>> So, just encrypting the data in transit and at rest does not help to be compliant with the rules. We need to make sure that data does not go out too.
>> The data that we are talking here is not just about the messages that are published to Anypoint MQ. It includes the apps running, transaction states, application logs, events, metric info and any other metadata. So, just replacing Anypoint MQ with a locally hosted ActiveMQ does NOT help.
>> The data that we are talking here is not just about the key/value pairs that are stored in Object Store. It includes the messages published, apps running, transaction states, application logs, events, metric info and any other metadata. So, just avoiding using Object Store does NOT help.
>> The only option left and also the right option in the given choices is to deploy application on runtime and control planes that are both within the jurisdiction.
