Question 56

You currently manage an e-commerce application that utilizes 25 identical compute resources to handle customer traffic. The stakeholders have asked you to create another 25 identical computeresources in order to deploy and test a new version of the software?
What is the most efficient process to create 25 additional compute resources that are identical to the first 25?

A.Clone the boot volume of 1 of the 25 servers. Use the boot volume clone to provision 25 more servers
B.Create a custom image from 1 of the 25 servers. Use this custom imageto provision 25 more servers
C.Create a manual backup of each boot volume belonging to the 25 servers. Restore each backup to create
25 new boot volumes, from which you will provision 25 more servers
D.Provision a new server and configure it to be identical to the first 25. Create a custom image from the new server, then use the custom image to provision 24 more servers

Question 57

D18912E1457D5D1DDCBD40AB3BF70D5D
Which two methods are supportedfor migrating your on-premises Oracle database to an Oracle Autonomous Transaction Processing (ATP) database in Oracle Cloud Infrastructure? (Choose two.)

A.Load text files into ATP using SQL Developer.
B.Use RMAN duplicate.
C.Use Oracle Data Pump.
D.Transfer the physical database files and re-create the database.
E.Use database backup and restore.

Question 58

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?

A.Ensure that your database host can connect to OCI object storage.
B.Ensure the database archiving mode is set to NOARCHIVELOG.
C.Make sure that the database is not active and running while the backup is in progress.
D.Don't restart the dcsagent program even if it has a status of stop/waiting.

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

Question 59

A customer has launched a compute Instance in the Virtual Cloud Network (VCN), which hasan Internet gateway, a service gateway, a default security lists and a default route table. Customer has opened up Port 22 in the security lists attached to the compute instance subnet, however is still unable to connect to compute instances using ssh.
Which option would remedy this situation?

A.Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table.
Destination CIDR: 0.0.0.0/0
Target: Internet Gateway (IGW)
B.Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow icmp traffic in addition to the port 22.
C.Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table.
Destination CIDR: 0.0.0.0/0
Target: Dynamic Routing Gateway (DRG)
D.Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table.
Destination CIDR: 0.0.0.0/0
Target: Service Gateway (SGW)
