A Mule application exposes an HTTPS endpoint and is deployed to three CloudHub workers that do not use static IP addresses. The Mule application expects a high volume of client requests in short time periods. What is the most cost-effective infrastructure component that should be used to serve the high volume of client requests?

• A.A customer-hosted load balancer
• B.The CloudHub shared load balancer
• C.An API proxy
• D.Runtime Manager autoscaling

In an organization, the InfoSec team is investigating Anypoint Platform related data traffic.
From where does most of the data available to Anypoint Platform for monitoring and alerting originate?

• A.From the Mule runtime or the API implementation, depending on the deployment model
• B.From various components of Anypoint Platform, such as the Shared Load Balancer, VPC, and Mule runtimes
• C.From the Mule runtime or the API Manager, depending on the type of data
• D.From the Mule runtime irrespective of the deployment model

A company is building an application network using MuleSoft's recommendations for various API layers.
What is the main (default) role of a process API in an application network?

• A.To secure and optimize the data synchronization processing of large data dumps between back-end systems
• B.To manage and process the secure direct communication between a back-end system and an end-user client of mobile device in the application network
• C.To automate parts of business processes by coordinating and orchestrating the invocation of other APIs in the application network
• D.To secure, Manage, and process communication with specific types of end-user client applications or devices in the application network

A company requires Mule applications deployed to CloudHub to be isolated between non-production and production environments. This is so Mule applications deployed to non-production environments can only access backend systems running in their customer-hosted non-production environment, and so Mule applications deployed to production environments can only access backend systems running in their customer-hosted production environment. How does MuleSoft recommend modifying Mule applications, configuring environments, or changing infrastructure to support this type of per-environment isolation between Mule applications and backend systems?

• A.Modify properties of Mule applications deployed to the production Anypoint Platform environments to prevent access from non-production Mule applications
• B.Configure firewall rules in the infrastructure inside each customer-hosted environment so that only IP addresses from the corresponding Anypoint Platform environments are allowed to communicate with corresponding backend systems
• C.Create non-production and production environments in different Anypoint Platform business groups
• D.Create separate Anypoint VPCs for non-production and production environments, then configure connections to the backend systems in the corresponding customer-hosted environments

Correct Answer: D

Correct Answer : Create separate Anypoint VPCs for non-production and production environments, then configure connections to the backend systems in the corresponding customer-hosted environments.
*****************************************
>> Creating different Business Groups does NOT make any difference w.r.t accessing the non-prod and prod customer-hosted environments. Still they will be accessing from both Business Groups unless process network restrictions are put in place.
>> We need to modify or couple the Mule Application Implementations with the environment. In fact, we should never implements application coupled with environments by binding them in the properties. Only basic things like endpoint URL etc should be bundled in properties but not environment level access restrictions.
>> IP addresses on CloudHub are dynamic until unless a special static addresses are assigned. So it is not possible to setup firewall rules in customer-hosted infrastrcture. More over, even if static IP addresses are assigned, there could be 100s of applications running on cloudhub and setting up rules for all of them would be a hectic task, non-maintainable and definitely got a good practice.
>> The best practice recommended by Mulesoft (In fact any cloud provider), is to have your Anypoint VPCs seperated for Prod and Non-Prod and perform the VPC peering or VPN tunneling for these Anypoint VPCs to respective Prod and Non-Prod customer-hosted environment networks.

Refer to the exhibit.

what is true when using customer-hosted Mule runtimes with the MuleSoft-hosted Anypoint Platform control plane (hybrid deployment)?

• A.Anypoint Runtime Manager initiates a network connection to a Mule runtime in order to deploy Mule applications
• B.The MuleSoft-hosted Shared Load Balancer can be used to load balance API invocations to the Mule runtimes
• C.API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane
• D.Anypoint Runtime Manager automatically ensures HA in the control plane by creating a new Mule runtime instance in case of a node failure

Correct Answer: C

Correct Answer : API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane.
*****************************************
>> We CANNOT use Shared Load balancer to load balance APIs on customer hosted runtimes

>> For Hybrid deployment models, the on-premises are first connected to Runtime Manager using Runtime Manager agent. So, the connection is initiated first from On-premises to Runtime Manager. Then all control can be done from Runtime Manager.
>> Anypoint Runtime Manager CANNOT ensure automatic HA. Clusters/Server Groups etc should be configured before hand.
Only TRUE statement in the given choices is, API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane. There are several references below to justify this statement.
