• Question 101:

  Refer to the exhibit.

  

  An organization uses a 2-node Mute runtime cluster to host one stateless API implementation. The API is accessed over HTTPS through a load balancer that uses round-robin for load distribution.

  What average performance change is guaranteed to happen, assuming all cluster nodes are fully operational?

  A. 50% reduction in the response time of the API

  B. 100% increase in the throughput of the API

  C. 50% reduction In the JVM heap memory consumed by each node

  D. 50% reduction In the number of requests being received by each node

  Correct Answer: D

• Question 103:

  According to MuleSoft, which major benefit does a Center for Enablement (C4E) provide for an enterprise and its lines of business?

  A. Enabling Edge security between the lines of business and public devices

  B. Centralizing project management across the lines of business

  C. Centrally managing return on investment (ROI) reporting from lines of business to leadership

  D. Accelerating self-service by the lines of business

  Correct Answer: B

• Question 104:

  A developer needs to discover which API specifications have been created within the organization before starting a new project.

  Which Anypoint Platform component can the developer use to find and try out the currently released API specifications?

  A. Anypoint Exchange

  B. Runtime Manager

  C. API Manager

  D. Object Store

  Correct Answer: A

• Question 105:

  What requires configuration of both a key store and a trust store for an HTTP Listener?

  A. Support for TLS mutual (two-way) authentication with HTTP clients

  B. Encryption of requests to both subdomains and API resource endpoints fhttPs://aDi.customer.com/ and https://customer.com/api)

  C. Encryption of both HTTP request and HTTP response bodies for all HTTP clients

  D. Encryption of both HTTP request header and HTTP request body for all HTTP clients

  Correct Answer: A

  1 way SSL : The server presents its certificate to the client and the client adds it to its list of trusted certificate. And so, the client can talk to the server. 2-way SSL: The same principle but both ways. i.e. both the client and the server has to establish trust between themselves using a trusted certificate. In this way of a digital handshake, the server needs to present a certificate to authenticate itself to client and client has to present its certificate to server.

  *

  TLS is a cryptographic protocol that provides communications security for your Mule app.

  *

  TLS offers many different ways of exchanging keys for authentication, encrypting data, and guaranteeing message integrity Keystores and Truststores Truststore and keystore contents differ depending on whether they are used for clients or

  servers:

  For servers: the truststore contains certificates of the trusted clients, the keystore contains the private and public key of the server. For clients: the truststore contains certificates of the trusted servers, the keystore contains the private and

  public key of the client. Adding both a keystore and a truststore to the configuration implements two-way TLS authentication also known as mutual authentication.

  *

  in this case, correct answer is Support for TLS mutual (two-way) authentication with HTTP clients.

  

• Question 106:

  An Organization has previously provisioned its own AWS VPC hosting various servers. The organization now needs to use Cloudhub to host a Mule application that will implement a REST API once deployed to Cloudhub, this Mule application must be able to communicate securely with the customer-provisioned AWS VPC resources within the same region, without being interceptable on the public internet.

  What Anypoint Platform features should be used to meet these network communication requirements between Cloudhub and the existing customer-provisioned AWS VPC?

  A. Add a Mulesoft hosted Anypoint VPC configured and with VPC Peering to the AWS VPC

  B. Configure an external identity provider (IDP) in Anypoint Platform with certificates from the customer provisioned AWS VPC

  C. Add a default API Whitelisting policy to API Manager to automatically whitelist the customer provisioned AWS VPC IP ranges needed by the Mule applicaton

  D. Use VM queues in the Mule application to allow any non-mule assets within the customer provisioned AWS VPC to subscribed to and receive messages

  Correct Answer: A

  Correct answer is: Add a Mulesoft hosted Anypoint VPC configured and with VPC Peering to the AWS VPC * Connecting to your Anypoint VPC extends your corporate network and allows CloudHub workers to access resources behind your corporate firewall.

  * You can connect on-premises data centers through a secured VPN tunnel, or a private AWS VPC through VPC peering, or by using AWS Direct Connect. MuleSoft Doc Reference : https://docs.mulesoft.com/runtime-manager/virtual-privatecloud

• Question 107:

  A high-volume eCommerce retailer receives thousands of orders per hour and requires notification of its order management, warehouse, and billing system for subsequent processing within 15 minutes of order submission through its website.

  Which integration technology, when used for its typical and intended purpose, meets the retailer's requirements for this use case?

  A. Managed File Transfer (MFT)

  B. Publish/Subscriber Messaging Bus (Pub/Sub)

  C. Enterprise Data Warehouse (EDW)

  D. Extract Transform Load (ETL)

  Correct Answer: D

• Question 108:

  A company wants its users to log in to Anypoint Platform using the company's own internal user credentials. To achieve this, the company needs to integrate an external identity provider (IdP) with the company's Anypoint Platform master organization, but SAML 2.0 CANNOT be used. Besides SAML 2.0, what single-sign-on standard can the company use to integrate the IdP with their Anypoint Platform master organization?

  A. SAML 1.0

  B. OAuth 2.0

  C. Basic Authentication

  D. OpenID Connect

  Correct Answer: D

  As the Anypoint Platform organization administrator, you can configure identity management in Anypoint Platform to set up users for single sign-on (SSO). Configure identity management using one of the following single sign-on standards: 1) OpenID Connect: End user identity verification by an authorization server including SSO 2) SAML 2.0: Web-based authorization including cross-domain SSO

• Question 109:

  A Mule application contains a Batch Job with two Batch Steps (Batch_Step_l and Batch_Step_2). A payload with 1000 records is received by the Batch Job.

  How many threads are used by the Batch Job to process records, and how does each Batch Step process records within the Batch Job?

  A. Each Batch Job uses SEVERAL THREADS for the Batch Steps Each Batch Step instance receives ONE record at a time as the payload, and RECORDS are processed IN PARALLEL within and between the two Batch Steps

  B. Each Batch Job uses a SINGLE THREAD for all Batch steps Each Batch step instance receives ONE record at a time as the payload, and RECORDS are processed IN ORDER, first through Batch_Step_l and then through Batch_Step_2

  C. Each Batch Job uses a SINGLE THREAD to process a configured block size of record Each Batch Step instance receives A BLOCK OF records as the payload, and BLOCKS of records are processed IN ORDER

  D. Each Batch Job uses SEVERAL THREADS for the Batch Steps Each Batch Step instance receives ONE record at a time as the payload, and BATCH STEP INSTANCES execute IN PARALLEL to process records and Batch Steps in ANY order as fast as possible

  Correct Answer: A

  *

  Each Batch Job uses SEVERAL THREADS for the Batch Steps

  *

  Each Batch Step instance receives ONE record at a time as the payload. It's not received in a block, as it does not wait for multiple records to be completed before moving to next batch step. (So Option D is out of choice)

  *

  RECORDS are processed IN PARALLEL within and between the two Batch Steps.

  *

  RECORDS are not processed in order. Let's say if second record completes batch_step_1 before record 1, then it moves to batch_step_2 before record 1. (So option C and D are out of choice)

  *

  A batch job is the scope element in an application in which Mule processes a message payload as a batch of records. The term batch job is inclusive of all three phases of processing: Load and Dispatch, Process, and On Complete.

  *

  A batch job instance is an occurrence in a Mule application whenever a Mule flow executes a batch job. Mule creates the batch job instance in the Load and Dispatch phase. Every batch job instance is identified internally using a unique String known as batch job instance id.
