Which two actions will occurwhen a back-end server that is registered with a backend set is marked to drain connections? (Choose two.)
Correct Answer: A,B
Explanation References:https://docs.cloud.oracle.com/iaas/Content/Balance/Reference/sessionpersistence.htm The Load Balancing service considers a server marked drain available for existing persisted sessions. New requests that are not part of an existing persisted session are not sent to that server.
Question 57
WhichDNS resource record type is used to point a host name to an IPv4 address?
You have been notified of an application failure indicating that one or more of the Oracle Cloud Infrastructure (OCI) resources have become unavailable. After scanning the Compute and Database consoles, you notice that one of the DB Systems is missing. What would you do to identify the reason for this missing resource?
Correct Answer: A
Explanation You can filter results by request actions to zero in on only the events with operations that interest you. For example, say that you only want to know about instances that were deleted during a specific time frame. Select a delete request action filter to see only the events with delete operations Reference:https://docs.cloud.oracle.com/en-us/iaas/Content/GSG/Tasks/usingaudit.htm
Question 59
You are running a mission-critical database application in Oracle Cloud Infrastructure (OCI). You take regular backups of your DB system to OCI object storage. Recently, you notice a failed database backup status in the console. What step can you take to determine the cause of the backup failure?
Correct Answer: A
Explanation Database backups can fail for various reasons. Typically, a backup fails because either the database host cannot access the object store, or there are problems on the host or with the database configuration. First need to determining the Problem In the Console, afailed database backup either displays a status of Failed or hangs in the Backup in Progress or Creating state. If the error message does not contain enough information to point you to a solution, you can use the database CLI and log files to gather moredata. Then, refer to the applicable section in this topic for a solution. Database Service Agent Issues Your Oracle Cloud Infrastructure Database makes use of an agent framework to allow you to manage your database through the cloud platform. Occasionallyyou might need to restart the dcsagent program if it has the status of stop/waiting to resolve a backup failure. Object Store Connectivity Issues Backing up your database to Oracle Cloud Infrastructure Object Storage requires that the host can connect tothe applicable Swift endpoint. You can test this connectivity by using a Swift user. Host Issues One or more of the following conditions on the database host can cause backups to fail: - Interactive Commands in the Oracle Profile - The File System Is Full - Incorrect Version of the Oracle Database Cloud Backup Module - Changes to the Site Profile File (glogin.sql) Database Issues An improper database state or configuration can lead to failed backups. - Database Not Running During Backup - Archiving ModeSet to NOARCHIVELOG (When you provision a new database, the archiving mode is set to ARCHIVELOG by default. This is the required archiving mode for backup operations) - Stuck Database Archiver Process and Backup Failures - Temporary Tablespace Errors - RMAN Configuration and Backup Failures - RMAN Retention Policy and Backup Failures - Loss of Objectstore Wallet File and Backup Failures TDE Wallet and Backup Failures - Incorrect TDE Wallet Location Specification - Incorrect State of the TDE Wallet -Incorrect Configuration Related to the TDE Wallet - Missing TDE Wallet File As this is not new provisioned database and already in the ARCHIVELOG , regular backups of DB system to OCI object storage in places, so the best answers are, - Ensure that your database host can connect to the OCI object storage - Restart the database service agent
