QUESTION NO:9

When implementing Transparent Data Encryption (TDE), which of the following answers describes the

correct order of the listed operations?

A. Create a wallet, create a master key, and create tables that contain encrypted columns.

B. Create tables that contain encrypted columns, create a wallet, create a master key, and open the

wallet.

C. Create a wallet, open the wallet, create a master key, and create tables that contain encrypted

columns.

D. Create a master key, create a wallet, open the wallet, and create tables that contain encrypted

columns.

Correct Answer: A

Explanation

Explanation/Reference:

Explanation:

Step 2: Create the Wallet

To create the wallet, use the ALTER SYSTEM SQL statement. By default, the Oracle wallet stores a

history of retired master keys, which enables you to change them and still be able to decrypt data that was

encrypted under an old master key …

ALTER SYSTEM SET ENCRYPTION KEY IDENTIFIED BY “password”; This statement generates the

wallet with a new encryption key and sets it as the current transparent data encryption master key.

…

Immediately after you create the wallet key, the wallet is open, and you are ready to start encrypting data.

QUESTION NO:2

Why would you use an auto-open wallet Instead of a standard encryption wallet?

A. To save on storage space

B. To increase the level of security on your encrypted data

C. To avoid manual Intervention to allow access to encrypted data after an automatic system restart

D. You must use an auto-open wallet with tablespace-based Transparent Data Encryption (TDE)

Correct Answer: C

Explanation

Explanation/Reference:

Explanation:

Beacose wallet is closed after restart and it has to be opened again for using TDE. You must enable auto

login if you want single sign-on access to multiple Oracle databases: such access is normally disabled, by

default. Sometimes the obfuscated auto login wallets are called “SSO wallets” because they support single

sign-on capability.

QUESTION NO:39

Identify the two ways that Oracle Database Vault interacts with other Oracle security options and features.

A. You can use Oracle Database Vault with Advanced Security.

B. You can use Oracle Database Vault with Oracle Audit Vault.

C. You cannot use Oracle Database Vault with a Virtual Private Database.

D. You cannot use Oracle Database Vault with Oracle Label Security.

Correct Answer: AB

Explanation

Explanation/Reference:

Explanation:

Oracle Audit Vault can collect the audit data for Oracle Database Vault. Transparent Data Encryption(part

of Advanced Security) complements Oracle Database Vault in that it provides data protection when the

data leaves the secure perimeter of the database.

QUESTION NO:16

Which two of the following are reasons to use Oracle Audit Vault?

A. To consolidate audit reports from multiple databases

B. To reduce the performance impact of auditing across multiple databases

C. To limit space required for audit trails

D. To ensure consistent auditing across multiple databases

Correct Answer: AC

Explanation

Explanation/Reference:

Explanation:

Audit repository exists for Oracle database (Release 10.2.0.4) to consolidate and manage audit trail

records.

By default, ARCHIVELOG mode is enabled in the Audit Vault Server database. The ARCHIVELOG mode

copies filled online redo logs to disk. This enables you to back up the database while it is open and being

accessed by users, and to recover the database to any desired point in time. You should monitor the disk

space usage for the redo logs.

QUESTION NO:30

Which of the following encryption algorithms is the default for Transparent Data Encryption (TDE)

tablespace encryption?

A. AES128

B. AES192

C. AES256

D. 3DES168

Correct Answer: B

Explanation

Explanation/Reference:

Explanation:

By default, TDE uses the AES encryption algorithm with a 192-bit key length (AES192).
