A00-451 Sample Exam Questions and Answers
| QUESTION: 1 |
| In a situation where a SAS Viya environment has undergone a series of backup and recovery operations over the past month, a SAS administrator needs to audit the recovery history to ensure compliance with the organization’s data management policies. Which of the following SAS Viya tools would the administrator use to view the detailed history of backup and recovery processes, including the timestamps and any possible errors that occurred during those operations? Option A: SAS Environment Manager backup and recovery service interface Option B: The backup command-line utility with appropriate flagsOption C: The sas-admin command-line interface with appropriate backup-history optionsOption D: Direct query on the internal SAS Viya PostgreSQL database tracking recovery operations |
| Correct Answer: C |
| Explanation/Reference: The `sas-admin` command-line interface, when used with the appropriate backup-history options, provides detailed information about backup and recovery operations, including timestamps, errors, and status. The `backup` command-line utility does not provide a view on the history but is used for taking backups. The internal PostgreSQL database used by SAS Viya could theoretically contain relevant data, but directly querying it is neither recommended nor supported for such an operation, and the SAS Environment Manager interface typically doesn’t provide detailed historical data of this kind. |
| QUESTION: 2 |
| When configuring stored credentials in SAS Viya, you are required to implement a change that will allow a group of users to access a specific database with a shared service account. This account’s credentials need to be updated monthly due to security policies. After the initial setup, what approach should be taken to update the stored credentials to minimize service disruption and manual intervention? Option A: Manually update the credentials every month by deleting and recreating the credentials object. Option B: Utilize the SAS Environment Manager to automate the update of the credentials using the scheduling feature. Option C: Implement a script using the SAS Security Model REST API to update the credentials, and schedule it to run with the operating system’s scheduler. Option D: Direct users to update their individually stored credentials within their personal profiles on a monthly basis. |
| Correct Answer: C |
| Explanation/Reference: Option C is the correct answer because it provides a method to automate the updating of stored credentials with minimal manual intervention. The SAS Security Model REST API can be used to programmatically update stored credentials, and these updates can be scheduled using the operating system’s scheduler (cron jobs in Unix/Linux or Task Scheduler in Windows), thereby adhering to the security policy without causing service disruption. Options A and D are manual processes and could cause user access issues every month. Option B is incorrect because while SAS Environment Manager allows for scheduling of certain tasks, it doesn’t directly provide a feature to automate the update of stored credentials. |
| QUESTION: 3 |
| In a SAS Viya environment, which supporting infrastructure service is responsible for centralized logging and monitoring of services? Option A: SAS Environment Manager Option B: Consul Option C: Vault Option D: Elasticsearch |
| Correct Answer: D |
| Explanation/Reference: Elasticsearch is a core component of the SAS Viya architecture that provides the centralized logging capabilities. It collects, indexes, and stores log data from various services in the environment, making it easier for administrators to search, monitor, and analyze the system’s operations in real time. This is crucial for maintaining system health and troubleshooting. |
| QUESTION: 4 |
| An administrator needs to ensure that specific business units can only access SAS Viya content that pertains to their business unit. The organization□s security policies also require that certain high-level summaries/dashboard views be accessible by all business units. Which of the following would be the best approach to meet these requirements? Option A: Assign all users to a common group for base-level access and create separate groups for each business unit to control specific content access. Option B: Create a folder structure reflecting the hierarchy of the business units and assign individual permissions on each folder. Option C: Grant all users administrative rights to ensure they can access all necessary content and rely on user discipline to not access other business units’ data. Option D: Use the SAS Viya guest account feature to allow universal access to high-level summaries and use individual user accounts to limit access to specific business unit content. |
| Correct Answer: A |
| Explanation/Reference: Creating a common group for all users allows the admin to give base-level access to high-level summaries/dashboard views that are meant to be available to everyone. By setting up additional groups for each business unit, the administrator can control access to sensitive content and ensure that users only have access to the content that is relevant to their business unit. This approach aligns with the principle of least privilege, limiting access rights for users to the bare minimum they need to perform their work, thus enhancing security. Options B might be partially correct, but it does not address the “common” access needed for high-level summaries, and option C would violate most organizations’ security policies. Option D is not practical, secure, or efficient. |
| QUESTION: 5 |
| You are assigned to configure a new caslib to ensure that analysts can load data more efficiently into memory when utilizing the SAS Viya environment. The data is currently stored in Hadoop. Which CASLIB statement will efficiently enable users to process data stored in Hadoop directly in-memory? Option A: caslib myHadoopCaslib datasource=(srctype=’hadoop’); Option B: caslib myHadoopCaslib datasource=(srctype=’path’); Option C: caslib myHadoopCaslib datasource=(srctype=’base’); Option D: caslib myHadoopCaslib datasource=(srctype=’hdfs’); |
| Correct Answer: D |
| Explanation/Reference: To work with data stored in Hadoop from SAS Viya, you must use the Hadoop Distributed File System (HDFS). The correct syntax for creating a caslib to access HDFS is by specifying `srctype=’hdfs’`. The CASLIB statement should point to ‘hdfs’ to acknowledge the Hadoop location, thus facilitating in-memory processing of the data stored in Hadoop. |
| QUESTION: 6 |
| After successfully deploying a patch update in your SAS Viya environment, how would you confirm that the updated components are functioning as expected without affecting current users’ workflows? Option A: Immediately direct all users to perform their regular tasks and monitor system performance. Option B: Use a phased approach by gradually introducing subsets of users to the updated system while monitoring performance metrics and log files. Option C: Revert the system to its pre-patch state and compare the performance against the updated system. Option D: Independently validate the updated components using automated tests designed for post- patch verification without involving active users. |
| Correct Answer: D |
| Explanation/Reference: To confirm that the updated components are functioning correctly after a patch update, conducting automated tests that are designed for post-patch verification is the safest and least disruptive method. These tests can include unit tests, regression tests, and integration tests, which are run without the need for users to be involved. This way, if there are any issues, they can be identified and resolved before opening up the system to end-users, ensuring that user workflows are not negatively impacted. |
