Oracle Exadata Database Service Overview

Oracle Exadata Database Service Overview

 

  • The Exadata Database Service has the same architecture as on-premises Exadata.
  • The Exadata Database Service protects its DATA by a series of security mechanisms and controls that are thoughtfully layered throughout the Oracle stack to protect the confidentiality, integrity, and availability of the network and the data within. 
  • The Exadata Database Service is enabled by default using Transparent Data Encryption (TDE) feature for protecting data at rest and native Oracle Net encryption and integrity capabilities to protect data in transit. 
  • The Exadata Database Service provides dedicated infrastructure whose allocated resources can be scaled up or down.
  • The Exadata Database Service can be deployed in the Oracle Public Cloud or in the Customer Data Center 
  • The Exadata Database Service can be run on Exadata Cloud@Customer in the Customer Data Center 
  • The Exadata Database Service elastic system configuration starts with a Quarter Rack and can grow Compute or Storage resources independently as needed.
  • For the Exadata Database Service the Customer manages everything above the Hypervisor using Cloud Automation via the UI or REST APIs. 

 

Customers can do the below activities

  • perform Backup and Recovery operations and enabling Data Guard
  • scale server and OCPU resources up and down
  • schedule when Oracle can conduct infrastructure maintenance

 Customers can not update and upgrade the below activities

  •  the VM operating system
  • ,network switches,
  • Grid Infrastructure software,
  • and Database home software 

 

 

 

Question 

Which two statements are true about Data Security with the Exadata Database Service?

 

  1. A) The Exadata Database Service protects its DATA by a series of security mechanisms and controls that are thoughtfully layered throughout the Oracle stack to protect the confidentiality, integrity, and availability of the network and the data within. 

 

  1. B) The Exadata Database Service is enabled by default using Transparent Data Encryption (TDE) feature for protecting data at rest and native Oracle Net encryption and integrity capabilities to protect data in transit. 

 

  1. C) The Exadata Database Service offers reduced pricing for using Transparent Data Encryption (TDE) to ensure that you can keep your DATA safe in the cloud.

 

  1. D) The Exadata Database Service allows customers to store their data unencrypted in the cloud if they need to save on the cost of encryption.

 

Explanation:

C and D :  wrong because TDE comes by default in Exadata Database Service

 

Question 

Which two statements are true about the Exadata Database Service?

 

  • A) The Exadata Database Service provides shared infrastructure with cloud automation tools that allow for allocated resources to be scaled up or down.
  • B) The Exadata Database Service has the same architecture as on-premises Exadata.
  • C) The Exadata Database Service provides dedicated infrastructure whose allocated resources can be scaled up or down.
  • D) The Exadata Database Service has the same architecture as on-premises Exadata.

Explanation:

B and D are same.

A is wrong because Exadata DB service can not be shared.

 

Which two statements are true about the Exadata Database Service?

 

  • A) The Exadata Database Service can be deployed in the Oracle Public Cloud or in the Customer Data Center 
  • B) The Exadata Database Service can be run on Exadata Cloud@Customer in the Customer Data Center 
  • C) The Exadata Database Service is only available in the Oracle Public Cloud
  • D) The Exadata Database Service is a Cloud Based Fully Managed Oracle Database Service

Explanation:

Exadata Database service can be run in Oracle Public cloud and Cloud@Customer in the Customer Data Center.

 

Which statement is true about the Exadata Database Service Configuration Options?

 

  • The Exadata Database Service elastic system configuration is only available in the Oracle Public Cloud.
  • You can start the Exadata Database Service elastic system configuration with as little as 1 Compute and 1 Storage server and grow as needed.
  • The Exadata Database Service elastic system configuration starts with a Quarter Rack and can grow Compute or Storage resources independently as needed.
  • The Exadata Database Service elastic system configuration starts with a Quarter Rack and grows with fixed shape increments.

Explanation:

After taking the Quarter Rack in Exadata Database Service elastic system configuration , we can increase compute nodes or storage nodes .That means we can have

But in on-premises Exadata , we have only eighth Rack, quarter Rack , Half Rack and Full Rack configurations.

 

What statement is true about managing the Exadata Database Service?

 

For the Exadata Database Service the Customer manages everything above the Hypervisor using Cloud Automation via the UI or REST APIs. 

 

The Exadata Database Service is a fully managed database service

For the Exadata Database Service Oracle manages the Infrastructure and the VM, while the customer manages the database using Cloud Automation via the UI or REST APIs

For the Exadata Database Service Oracle manages the Infrastructure, VM, and Grid Infrastructure while the customer manages the database using Cloud Automation via the UI or REST APIs.

 

Which lifecycle management task customers cannot accomplish with cloud automation on the Exadata Database Service?

 

Customers can perform Backup and Recovery operations and enabling Data Guard

Customers can update and upgrade the VM operating system, network switches, Grid Infrastructure software, and Database home software 

Customers can scale server and OCPU resources up and down

Customers can schedule when Oracle can conduct infrastructure maintenance
