Question 1

To temporarily add workers that persist only until the CAS server restarts, which Ansible playbook should be used?

Ainstall-onlyyml

Bsite yml

Cupdate-only yml

Ddeploy-casworker yml

Answer : D

To add workers that persist only until the CAS server restarts, you should use the deploy-casworker.yml playbook. This playbook will create new workers, configure them and apply any necessary hotfixes. The workers will be destroyed when the CAS server is restarted, so you will need to run the playbook again if you want them to persist after the restart.

Question 2

The logging for the SAS Configuration Server is controlled by which file?

Acasconfig lua

Blogconfig json

Clogconfig xml

Dconfig-consul json

Answer : C

The logging for the SAS Configuration Server is controlled by the logconfig.xml file. This file is located in the config folder of the SAS Configuration Server installation. It is used to specify the type of logging, the log levels, and the location of the log files.

AAll code must be submitted in batch.

BIt includes SAS Studio which connects with the SAS Compute Service

CAll code must be submitted in batch or via Enterprise Guide

DIt includes SAS Studio which connects to the SAS Workspace Server.

According to the official SAS Viya 3.5 documentation, a SAS programming-only deployment includes SAS Studio, which connects to the SAS Workspace Server. You can find this information in the SAS Viya 3.5 Administering Guide page 18

Question 5

Which Rule Target (URI) gives users the ability to view reports in SAS Visual Analytics?

ASASVisualAnalytics/**

B/SASVisualAnalytics/

CSASVisualAnalytics/*

DSASVisualAnalytics/*/*

Answer : C

The exact text from the SAS documentation states that the Rule Target (URI) SASVisualAnalytics/* gives users the ability to view reports in SAS Visual Analytics. The '*' symbol is a wildcard that allows the user to view all the reports in the SAS Visual Analytics application.

Question 6

All servers and services in a distributed SAS Viya Environment are stopped. An administrator needs to start them in the correct order. Which server must be started first?

ASAS Infrastructure Data Server (PostgreSQL)

BSAS Secrets Manager (Vault)

CSAS Message Broker (RabbitMQ)

DSAS Configuration Server (Consul server)

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.

Question 7

You have an MPP SAS Viva environment with a primary CAS Controller and a backup CAS Controller. The primary controller fails and your backup controller is now active.

Which task will you need to complete during the process of recovering the primary controller?

ADelete the permstore from the backup controller.

BStop SAS services on all the CAS workers.

CRestore the permstore from the backup controller to the primary controller.

DRestore CASDISKCACHE from the backup controller to the primary controller.

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.
