Refer to the exhibit.

Question # 34

An organization is sizing an Anypoint VPC for the non-production deployments of those Mule applications that connect to the organization's on-premises systems. This applies to approx. 60 Mule applications. Each application is deployed to two CloudHub i workers. The organization currently has three non-production environments (DEV, SIT and UAT) that share this VP

C.  

The AWS region of the VPC has two AZs.

The organization has a very mature DevOps approach which automatically progresses each application through all non-production environments before automatically deploying to production. This process results in several Mule application deployments per hour, using CloudHub's normal zero-downtime deployment feature.

What is a CIDR block for this VPC that results in the smallest usable private IP address range?

Options:

A.  

10.0.0.0/26 (64 IPS)

B.  

10.0.0.0/25 (128 IPs)

C.  

10.0.0.0/24 (256 IPs)

D.  

10.0.0.0/22 (1024 IPs)

Question # 36

An application deployed to a runtime fabric environment with two cluster replicas is designed to periodically trigger of flow for processing a high-volume set of records from the source system and synchronize with the SaaS system using the Batch job scope

After processing 1000 records in a periodic synchronization of 1 lakh records, the replicas in which batch job instance was started went down due to unexpected failure in the runtime fabric environment

What is the consequence of losing the replicas that run the Batch job instance?

Options:

A.  

The remaining 99000 records will be lost and left and processed

B.  

The second replicas will take over processing the remaining

99000 records

C.  

A new replacement replica will be available and will be process all 1,00,000 records from scratch leading to duplicate record processing

D.  

A new placement replica will be available and will take or processing the remaining 99,000 records

Question # 37

An organization needs to enable access to their customer data from both a mobile app and a web application, which each need access to common fields as well as certain unique fields. The data is available partially in a database and partially in a 3rd-party CRM system. What APIs should be created to best fit these design requirements?

Question # 37

Options:

A.  

A Process API that contains the data required by both the web and mobile apps, allowing these applications to invoke it directly and access the data they need thereby providing the flexibility to add more fields in the future without needing API changes.

B.  

One set of APIs (Experience API, Process API, and System API) for the web app, and another set for the mobile app.

C.  

Separate Experience APIs for the mobile and web app, but a common Process API that invokes separate System APIs created for the database and CRM system

D.  

A common Experience API used by both the web and mobile apps, but separate Process APIs for the web and mobile apps that interact with the database and the CRM System.

Question # 39

An external API frequently invokes an Employees System API to fetch employee data from a MySQL database. The architect must design a caching strategy to query the database only when there Is an update to the Employees table or else return a cached response in order to minimize the number of redundant transactions being handled by the database.

Options:

A.  

Use an On Table Row operation configured with the Employees table, call invalidate cache, and hardcode the new Employees data to cache. Use an object-store-caching-strategy and set the expiration interval to 1 hour.

B.  

Use an On Table Row operation configured with the Employees table and cail invalidate cache. Use an object-store-caching-strategy and the default expiration interval.

C.  

Use a Scheduler with a fixed frequency set to every hour to trigger an invalidate cache flow. Use an object-store-caching-strategy and the default expiration interval.

D.  

Use a Scheduler with a fixed frequency set to every hour, triggering an invalidate cache flow. Use an object-store-caching-strategy and set the expiration interval to 1 hour.

Question # 40

An organization has decided on a cloudhub migration strategy that aims to minimize the organizations own IT resources. Currently, the organizational has all of its Mule applications running on its own premises and uses an premises load balancer that exposes all APIs under the base URL https://api.acme.com

As part of the migration strategy, the organization plans to migrate all of its Mule applications and load balancer to cloudhub

What is the most straight-forward and cost effective approach to the Mule applications deployment and load balancing that preserves the public URLs?

Options:

A.  

Deploy the Mule applications to Cloudhub

Update the CNAME record for an api.acme.com in the organizations DNS server pointing to the A record of a cloudhub dedicated load balancer(DLB)

Apply mapping rules in the DLB to map URLs to their corresponding Mule applications

B.  

For each migrated Mule application, deploy an API proxy Mule application to Cloudhub with all applications under the control of a dedicated load balancer(CLB)

Update the CNAME record for api.acme.com in the organization DNS server pointing to the A record of a cloudhub dedicated load balancer(DLB)

Apply mapping rules in the DLB to map each API proxy application to its corresponding Mule applications

C.  

Deploy the Mule applications to Cloudhub

Create CNAME record for api.acme.com in the Cloudhub Shared load balancer (SLB) pointing to the A record of the on-premise load balancer

Apply mapping rules in the SLB to map URLs to their corresponding Mule applications

D.  

Deploy the Mule applications to Cloudhub

Update the CNAME record for api.acme.com in the organization DNS server pointing to the A record of the cloudhub shared load balancer(SLB)

Apply mapping rules in the SLB to map URLs to their corresponding Mule applications.
