Question #1
You want all your colleagues to be able to access the compute node associated with an Oracle Database Cloud Database as a Service (DBaaS) instance. You want them to do so by using a custom host name rather than an IP address regardless of the client machine (personal or provided by the company) that they use for the access.
How would you enable this access?
  1. A
    Configure the Advanced Security Option (ASO).
  2. B
    Enable secure access to the DBaaS instance VM and database instance from remote hosts by using SSH.
  3. C
    Contact the administrator of your company’s intranet DNS and request a custom DNS record for the compute node’s public IP address.
  4. D
    Edit the machine’s /etc/hosts file.
  5. E
    Resolve your domain name to the IP address of the DBaaS compute node by using the third-party domain registration vendor console.

Correct Answer:
C
You can associate a custom host name or domain name to the public IP address of a compute node associated with your Oracle Database Cloud Service environment.
To associate a custom host name to the public IP address of a compute node, contact the administrator of your DNS (Domain Name Service) and request a custom DNS record for the compute nodes public IP address. For example, if your domain is example.com and you wanted to use clouddb1 as the custom host name for a compute node, you would request a DNS record that associates clouddb1.example.com to your compute node's public IP address.

Question #2
With Oracle Database Cloud Service as the subscription type, you must configure a database for Backup and Recovery.
Which two options do you have to back up your database instance?
  1. A
    No backups required. You are responsible for configuring the database backups.
  2. B
    Backup to cloud storage and VM block storage. Ten days worth of backups are kept, with five most recent days worth of backups available directly on VM block storage.
  3. C
    Backup to Oracle Cloud Service storage volumes that is equal to five times the value that was provided in Usable Data Storage when the instance was created.
  4. D
    Backup to cloud storage and VM block storage. Fourteen days worth of backups are kept, with seven most recent days worth of backups available directly on

Correct Answer:
AC
When creating a new database deployment on Oracle Database Cloud Service, you choose whether you want automatic backups to be configured for the database. Your choices are:
Both Cloud Storage and Local Storage30 days' worth of backups are kept, with the 7 most recent days' worth available directly on the compute nodes local storage.
Cloud Storage Only30 days' worth of backups are kept, with all backups on cloud storage.
Noneautomatic backups are not configured.

Question #3
Users must be granted roles to manage Cloud services.
Which three statements are true about roles and role assignment in Database as a Service (DBaaS)?
  1. A
    Service administrators can assign and remove roles only for users of the services that they manage.
  2. B
    The DBaaS Database Administrator role permits granting the DBaaS Database Administrator or DBaaS Database Operator role to existing users.
  3. C
    Identity domain administrators can assign and remove roles for users in any identity domains.
  4. D
    The DBaaS Database Operator role permits the ability to scale, patch, and backup or restore service instances.
  5. E
    DBaaS network administrators can grant access privileges to designated users.

Correct Answer:
ADE
A: A Service administrator manages administrative functions related to Oracle Cloud services within an identity domain.
D: The privileges given to the DBaaS Database Administrator role include:
Can scale, patch, and back up or restore database deployments
Incorrect Answers:
B: The privileges given to the DBaaS Database Administrator role are:
✑ Can create and delete database deployments
✑ Can scale, patch, and back up or restore database deployments
✑ Can monitor and manage service usage in Oracle Cloud
C: Only identity domain administrators can manage user accounts, and they are allowed to add, modify, and remove user accounts only in the identity domains that they have been designated to administer.

Question #4
Which users are created and can be used for database and host management of your DBaaS database servers?
  1. A
    root, opc and oracle users
  2. B
    root, oracle and cloud users
  3. C
    root and oracle users
  4. D
    opc and oracle users
  5. E
    cloud and oracle users

Correct Answer:
D
Linux user accounts that are provisioned on an Oracle Database Cloud Service deployment that hosts an Oracle Real Application Clusters (Oracle RAC) database:
* opc
The system administrator account you use to connect to the compute node using SSH. This user can use the sudo command to perform operations that require root-user access.
* oracle
The Oracle Database administrator account you use to access the system and perform non-root database administration tasks.
* grid
The Oracle Grid Infrastructure administrator account you use to perform ASM, ACFS, and clusterware administration tasks.
* root
The root administrator for the system. You do not have direct access to this account. To perform operations that require root-user access, use the sudo command as the opc user.

Question #5
Which two situations require that your Database as a Service (DBaaS) instance be scaled up?
  1. A
    The DBaaS instance is maxed out on semaphore sets.
  2. B
    The database instance has reached the limit in the license_max_sessions database parameter.
  3. C
    The DBaaS instance is maxed out on CPU.
  4. D
    The database instance is out of space in the sysaux and system tablespaces.
  5. E
    The DBaaS instance is maxed out on storage.
  6. F
    The DBaaS instance is maxed out on semaphores.

Correct Answer:
CE
Existing DBCS instances may scale up to bigger shapes in OCPU, Memory and Storage for vertical scaling. For horizontal scaling, DBCS provides RAC with the
Extreme Performance option currently allowing applications to scale up to 2 nodes, each with a max of 16 OCPU shapes.
Note: An Oracle CPU (OCPU) provides CPU capacity equivalent of one physical core of an Intel Xeon processor with hyper threading enabled. Each OCPU corresponds to two hardware execution threads, known as vCPUs.
