SAS Certified Specialist Administration of SAS Viya 3.5 A00-251 Exam Questions

Answer : B

According to the official SAS Viya 3.5 documentation, you can use the current software order to update your existing SAS Viya environment with the latest hotfixes. You can find this information in the SAS Viya 3.5 Administering Guide page 4.

To apply the newest hot fixes available to your deployed SAS Viya environment, you would update your environment using a current software order. A hot fix is a software update that addresses a specific problem or issue, and it is typically delivered in the form of a patch or service pack. Hot fixes are typically applied to an existing software installation and do not require a new software order or an upgrade of the entire software package.

Updating using a new software order or upgrading using a new software order is not required for applying hot fixes, these actions are usually taken when adding new functionality or new version of the software. Upgrading using a current software order is not an applicable option as the term 'upgrade' is usually related to a new version and hot fixes are small updates to the current version.

Answer : C

When promoting content from SAS 9 to SAS Viya, the correct order of tasks after you've created an initial map of system information is to promote content, promote internal groups, and then promote data definitions. Content promotion involves copying SAS 9 content into Viya, while the promotion of internal groups and data definitions involves creating Viya roles and data objects.

Answer : B

CAS can support multiple backup controllers in a distributed architecture, which can improve performance and provide redundancy. Additionally, a backup controller can be added after the initial deployment, which can be useful for managing a large number of CAS workers.

It is false statement because CAS supports adding more than one backup controller in a CAS server architecture. The CAS Backup Controller is a separate process that runs alongside the CAS Controller and monitors the health of the CAS processes. It can be deployed on a separate machine or on the same machine as a CAS worker. The backup controller can be added during the initial deployment or after the initial deployment.

A CAS Backup controller is used in a distributed CAS server architecture but it can also be used in a single machine architecture too. CAS Backup controller provides an additional level of redundancy, in case the primary CAS controller goes down, it can take over its responsibilities.

Answer : C

When recovering a primary controller, you need to restore the permstore from the backup controller to the primary controller. The permstore contains the state of the CAS session and other important information related to the CAS environment, such as configuration, metadata, and user data. Restoring the permstore from the backup controller allows the primary controller to resume operation with minimal data loss.

The process of restoring the permstore from the backup controller to the primary controller can be done by using the sas-admin permstore-restore command.

It is important to note that, before restoring the permstore, you should stop SAS services on all the CAS workers, in order to avoid data corruption during the restore process. Also, it is not recommended to delete the permstore from the backup controller, as it is useful in case of primary controller failure. CASDISKCACHE is used for caching purpose, it's not related to permstore or primary controller failure.

Answer : A

According to the official SAS Viya 3.5 documentation, data tables on the local file system are not backed up when using SAS Backup and Restore. You can find this information in the SAS Viya 3.5 Administering Guide page 22.

Answer : D

In a distributed SAS Viya environment, the SAS Configuration Server (Consul server) must be started first. The Consul server is the foundation of the SAS Viya environment and provides service discovery and configuration management for all other servers and services. It is responsible for maintaining the configuration information and state of the SAS Viya environment, including the location and status of all servers and services.

Answer : A, D

When you add on a new product or upgrade to a newer version of SAS Viya, you will need to obtain a new software order. This is because these changes involve additional or updated software components that are not covered under your existing license agreement.

Note: If you are only applying a hotfix or updating TLS certificates, you do not need to obtain a new software order. These changes do not involve additional or updated software components and can be done under your existing license agreement.
