質問 # 28
Mule application muleA deployed in cloudhub uses Object Store v2 to share data across instances. As a part of new requirement , application muleB which is deployed in same region wants to access this Object Store.
Which of the following option you would suggest which will have minimum latency in this scenario?
- A. Object Store REST API
- B. Both of the above option will have same latency
- C. Object Store of one mule application cannot be accessed by other mule application.
- D. Object Store connector
正解：A
解説：
Explanation
V2 Rest API is recommended for on premise applications to access Object Store. It also comes with overhead of encryption and security of using rest api. With Object Store v2, the API call is localized to the same data center as the Runtime Manager app.
But in this case requirement is to access the OS of other mule application and not the same mule application.
You can configure a Mule app to use the Object Store REST API to store and retrieve values from an object store in another Mule app.
However, Object Store v2 is not designed for app-to-app communication.

質問 # 31
Organization wants to achieve high availability goal for Mule applications in customer hosted runtime plane.
Due to the complexity involved, data cannot be shared among of different instances of same Mule application.
What option best suits to this requirement considering high availability is very much critical to the organization?
- A. High availability can be achieved only in CloudHub
- B. The cluster can be configured
- C. Use persistent object store
- D. Use third party product to implement load balancer
正解：D
解説：
Explanation
High availability is about up-time of your application
A) High availability can be achieved only in CloudHub isn't correct statement. It can be achieved in customer hosted runtime planes as well B) An object store is a facility for storing objects in or across Mule applications. Mule runtime engine (Mule) uses object stores to persist data for eventual retrieval. It can be used for disaster recovery but not for High Availability. Using object store can't guarantee that all instances won't go down at once. So not an appropriate choice.

- A. An Object Store
- B. A database
- C. A message broker
- D. An HTTP Load Balancer
正解：D
解説：
Explanation
Correct answer is An HTTP Load Balancer.
Key thing to note here is that we are deploying application to customer hosted Mule runtime. This means we will need load balancer to route the requests to different instances of the cluster.
Rest all options are distractors and their requirement depends on project use case.
質問 # 46
An organization has several APIs that accept JSON data over HTTP POST. The APIs are all publicly available and are associated with several mobile applications and web applications. The organization does NOT want to use any authentication or compliance policies for these APIs, but at the same time, is worried that some bad actor could send payloads that could somehow compromise the applications or servers running the API implementations. What out-of-the-box Anypoint Platform policy can address exposure to this threat?
- A. Apply a Header injection and removal policy that detects the malicious data before it is used
- B. Apply a JSON threat protection policy to all APIs to detect potential threat vectors
- C. Apply an IP blacklist policy to all APIs; the blacklist will Include all bad actors
- D. Shut out bad actors by using HTTPS mutual authentication for all API invocations
正解：B
解説：
Explanation
We need to note few things about the scenario which will help us in reaching the correct solution.
Point 1 : The APIs are all publicly available and are associated with several mobile applications and web applications. This means Apply an IP blacklist policy is not viable option. as blacklisting IPs is limited to partial web traffic. It can't be useful for traffic from mobile application Point 2 : The organization does NOT want to use any authentication or compliance policies for these APIs.
This means we can not apply HTTPS mutual authentication scheme.
Header injection or removal will not help the purpose.
By its nature, JSON is vulnerable to JavaScript injection. When you parse the JSON object, the malicious code inflicts its damages. An inordinate increase in the size and depth of the JSON payload can indicate injection.
Applying the JSON threat protection policy can limit the size of your JSON payload and thwart recursive additions to the JSON hierarchy.
Hence correct answer is Apply a JSON threat protection policy to all APIs to detect potential threat vectors
質問 # 47
Mule application is deployed to Customer Hosted Runtime. Asynchronous logging was implemented to improved throughput of the system. But it was observed over the period of time that few of the important exception log messages which were used to rollback transactions are not working as expected causing huge loss to the Organization. Organization wants to avoid these losses. Application also has constraints due to which they cant compromise on throughput much. What is the possible option in this case?
- A. Persistent memory storage should be used in such scenarios
- B. Logging needs to be changed from asynchronous to synchronous
- C. Mixed configuration of asynchronous or synchronous loggers should be used to log exceptions via synchronous way
- D. External log appender needs to be used in this case
正解：C
解説：
Explanation
Correct approach is to use Mixed configuration of asynchronous or synchronous loggers shoud be used to log exceptions via synchronous way Asynchronous logging poses a performance-reliability trade-off. You may lose some messages if Mule crashes before the logging buffers flush to the disk. In this case, consider that you can have a mixed configuration of asynchronous or synchronous loggers in your app. Best practice is to use asynchronous logging over synchronous with a minimum logging level of WARN for a production application. In some cases, enable INFO logging level when you need to confirm events such as successful policy installation or to perform troubleshooting. Configure your logging strategy by editing your application's src/main/resources/log4j2.xml file

質問 # 50
What condition requires using a CloudHub Dedicated Load Balancer?
- A. When server-side load-balanced TLS mutual authentication is required between API implementations and API clients
- B. When cross-region load balancing is required between separate deployments of the same Mule application
- C. When API invocations across multiple CloudHub workers must be load balanced
- D. When custom DNS names are required for API implementations deployed to customer-hosted Mule runtimes
正解：A
解説：
Explanation
Correct answer is When server-side load-balanced TLS mutual authentication is required between API implementations and API clients CloudHub dedicated load balancers (DLBs) are an optional component of Anypoint Platform that enable you to route external HTTP and HTTPS traffic to multiple Mule applications deployed to CloudHub workers in a Virtual Private Cloud (VPC). Dedicated load balancers enable you to: * Handle load balancing among the different CloudHub workers that run your application. * Define SSL configurations to provide custom certificates and optionally enforce two-way SSL client authentication. * Configure proxy rules that map your applications to custom domains. This enables you to host your applications under a single domain
