ARC720 Sample Exam Questions and Answers
| QUESTION: 1 |
| An API implementation is deployed on a single worker on CloudHub and invoked by external API clients (outside of CloudHub). How can an alert be set up that is guaranteed to trigger AS SOON AS that API implementation stops responding to API invocations? Option A: Implement a heartbeat/health check within the API and invoke it from outside the Anypoint Platform and alert when the heartbeat does not respond Option B: Configure a “worker not responding” alert in Anypoint Runtime Manager Option C: Handle API invocation exceptions within the calling API client and raise an alert from that API client when the API Is unavailable Option D: Create an alert for when the API receives no requests within a specified time period |
| Correct Answer: B |
| Explanation/Reference: Explanation Correct Answer: Configure a “Worker not responding” alert in Anypoint Runtime Manager. ***************************************** >> All the options eventually helps to generate the alert required when the application stops responding. >> However, handling exceptions within calling API and then raising alert from API client is inappropriate and silly. There could be many API clients invoking the API implementation and it is not ideal to have this setup consistently in all of them. Not a realistic way to do. >> Implementing a health check/ heartbeat with in the API and calling from outside to detmine the health sounds OK but needs extra setup for it and same time there are very good chances of generating false alarms when there are any intermittent network issues between external tool calling the health check API on API implementation. The API implementation itself may not have any issues but due to some other factors some false alarms may go out. >> Creating an alert in API Manager when the API receives no requests within a specified time period would actually generate realistic alerts but even here some false alarms may go out when there are genuinely no requests from API clients. The best and right way to achieve this requirement is to setup an alert on Runtime Manager with a condition “Worker not responding”. This would generate an alert AS SOON AS the workers become unresponsive. |
| QUESTION: 2 |
| The responses to some HTTP requests can be cached depending on the HTTP verb used in the request. According to the HTTP specification, for what HTTP verbs is this safe to do? Option A: PUT, POST, DELETE Option B: GET, HEAD, POST Option C: GET, PUT, OPTIONS Option D: GET, OPTIONS, HEAD |
| Correct Answer: D |
| Explanation/Reference: Explanation Correct Answer: GET, OPTIONS, HEAD |
| QUESTION: 3 |
| The application network is recomposable: it is built for change because it “bends but does not break” Option A: TRUE Option B: FALSE |
| Correct Answer: A |
| Explanation/Reference: ***************************************** >> Application Network is a disposable architecture. >> Which means, it can be altered without disturbing entire architecture and its components. >> It bends as per requirements or design changes but does not break |
| QUESTION: 4 |
| An organization has implemented a Customer Address API to retrieve customer address information. This API has been deployed to multiple environments and has been configured to enforce client IDs everywhere. A developer is writing a client application to allow a user to update their address. The developer has found the Customer Address API in Anypoint Exchange and wants to use it in their client application. What step of gaining access to the API can be performed automatically by Anypoint Platform? Option A: Approve the client application request for the chosen SLA tier Option B: Request access to the appropriate API Instances deployed to multiple environments using the client application’s credentials Option C: Modify the client application to call the API using the client application’s credentials Option D: Create a new application in Anypoint Exchange for requesting access to the API |
| Correct Answer: A |
| Explanation/Reference: Explanation Correct Answer: Approve the client application request for the chosen SLA tier ***************************************** >> Only approving the client application request for the chosen SLA tier can be automated >> Rest of the provided options are not valid |
| QUESTION: 5 |
| A set of tests must be performed prior to deploying API implementations to a staging environment. Due to data security and access restrictions, untested APIs cannot be granted access to the backend systems, so instead mocked data must be used for these tests. The amount of available mocked data and its contents is sufficient to entirely test the API implementations with no active connections to the backend systems. What type of tests should be used to incorporate this mocked data? Option A: Integration tests Option B: Performance tests Option C: Functional tests (Blackbox) Option D: Unit tests (Whitebox) |
| Correct Answer: D |
| Explanation/Reference: Explanation Correct Answer: Unit tests (Whitebox) ***************************************** |
| QUESTION: 6 |
| What is a typical result of using a fine-grained rather than a coarse-grained API deployment model to implement a given business process? Option A: A decrease in the number of connections within the application network supporting the business process Option B: A higher number of discoverable API-related assets in the application network Option C: A better response time for the end user as a result of the APIs being smaller in scope and complexity Option D: An overall tower usage of resources because each fine-grained API consumes less resources |
| Correct Answer: B |
| Explanation/Reference: Explanation Correct Answer: A higher number of discoverable API-related assets in the application network. ***************************************** >> We do NOT get faster response times in fine-grained approach when compared to coarse-grained approach. >> In fact, we get faster response times from a network having coarse-grained APIs compared to a network having fine-grained APIs model. The reasons are below. Fine-grained approach: 1. will have more APIs compared to coarse-grained 2. So, more orchestration needs to be done to achieve a functionality in business process. 3. Which means, lots of API calls to be made. So, more connections will needs to be established. So, obviously more hops, more network i/o, more number of integration points compared to coarse-grained approach where fewer APIs with bulk functionality embedded in them. 4. That is why, because of all these extra hops and added latencies, fine-grained approach will have bit more response times compared to coarse-grained. 5. Not only added latencies and connections, there will be more resources used up in fine- grained approach due to more number of APIs. That’s why, fine-grained APIs are good in a way to expose more number of resuable assets in your network and make them discoverable. However, needs more maintenance, taking care of integration points, connections, resources with a little compromise w.r.t network hops and response times. |
| QUESTION: 7 |
| An API client calls one method from an existing API implementation. The API implementation is later updated. What change to the API implementation would require the API client’s invocation logic to also be updated? Option A: When the data type of the response is changed for the method called by the API client Option B: When a new method is added to the resource used by the API client Option C: When a new required field is added to the method called by the API client Option D: When a child method is added to the method called by the API client |
| Correct Answer: C |
| Explanation/Reference: Explanation Correct Answer: When a new required field is added to the method called by the API client ***************************************** >> Generally, the logic on API clients need to be updated when the API contract breaks. >> When a new method or a child method is added to an API , the API client does not break as it can still continue to use its existing method. So these two options are out. >> We are left for two more where “datatype of the response if changed” and “a new required field is added”. >> Changing the datatype of the response does break the API contract. However, the question is insisting on the “invocation” logic and not about the response handling logic. The API client can still invoke the API successfully and receive the response but the response will have a different datatype for some field. >> Adding a new required field will break the API’s invocation contract. When adding a new required field, the API contract breaks the RAML or API spec agreement that the API client/API consumer and API provider has between them. So this requires the API client invocation logic to also be updated. |
| QUESTION: 8 |
| An API experiences a high rate of client requests (TPS) vwth small message paytoads. How can usage limits be imposed on the API based on the type of client application? Option A: Use an SLA-based rate limiting policy and assign a client application to a matching SLA tier based on its type Option B: Use a spike control policy that limits the number of requests for each client application type Option C: Use a cross-origin resource sharing (CORS) policy to limit resource sharing between client applications, configured by the client application type Option D: Use a rate limiting policy and a client ID enforcement policy, each configured by the client application type |
| Correct Answer: A |
| Explanation/Reference: Correct Answer: Use an SLA-based rate limiting policy and assign a client application to a matching SLA tier based on its type. ***************************************** >> SLA tiers will come into play whenever any limits to be imposed on APIs based on client type |
| QUESTION: 9 |
| What is true about automating interactions with Anypoint Platform using tools such as Anypoint Platform REST APIs, Anypoint CU, or the Mule Maven plugin? Option A: Access to Anypoint Platform APIs and Anypoint CU can be controlled separately through the roles and permissions in Anypoint Platform, so that specific users can get access to Anypoint CLI white others get access to the platform APIs Option B: Anypoint Platform APIs can ONLY automate interactions with CloudHub, while the Mule Maven plugin is required for deployment to customer-hosted Mule runtimes Option C: By default, the Anypoint CLI and Mule Maven plugin are NOT included in the Mule runtime, so are NOT available to be used by deployed Mule applications Option D: API policies can be applied to the Anypoint Platform APIs so that ONLY certain LOBs have access to specific functions |
| Correct Answer: C |
| Explanation/Reference: Explanation Correct Answer: By default, the Anypoint CLI and Mule Maven plugin are NOT included in the Mule runtime, so are NOT available to be used by deployed Mule applications ***************************************** >> We CANNOT apply API policies to the Anypoint Platform APIs like we can do on our custom written API instances. So, option suggesting this is FALSE. >> Anypoint Platform APIs can be used for automating interactions with both CloudHub and customer-hosted Mule runtimes. Not JUST the CloudHub. So, option opposing this is FALSE. >> Mule Maven plugin is NOT mandatory for deployment to customer-hosted Mule runtimes. It just helps your CI/CD to have smoother automation. But not a compulsory requirement to deploy. So, option opposing this is FALSE. >> We DO NOT have any such special roles and permissions on the platform to separately control access for some users to have Anypoint CLI and others to have Anypoint Platform APIs. With proper general roles/permissions (API Owner, Cloudhub Admin etc..), one can use any of the options (Anypoint CLI or Platform APIs). So, option suggesting this is FALSE. Only TRUE statement given in the choices is that – Anypoint CLI and Mule Maven plugin are NOT included in the Mule runtime, so are NOT available to be used by deployed Mule applications. Maven is part of Studio or you can use other Maven installation for development. CLI is convenience only. It is one of many ways how to install app to the runtime. These are definitely NOT part of anything except your process of deployment or automation. |
