No.# right, majority of the answer on this cram exam is incorrect. TDE wallet is different from the wallet you use to connect to ADB

No.# If the client is behind a firewall and your network configuration requires an HTTP proxy to connect to the internet, you need to use the JDBC Thin Client 18.1 or higher which enables connections through HTTP proxies

No.# https://taliphakanozturken.wordpress.com/2020/04/05/connecting-to-an-oracle-autonomous-database-using-sql-developer/

No.# C is correct

No.# D is not possible.
Only B,C are correct

No.# A is correct

No.# Answer C

No.# C

No.# Hello,
Some of the answers are wrong.

No.# BCD are right

No.# The correct answer are C and D

No.# Answer should be C and D.

No.# D is right

No.# AB are correct

No.# BD are correct

No.# CD correct,

No.# BCE Correct

No.# The answer is D. You simply specify the number of OCPUs and the storage capacity in TB's for the database. At any time, you may scale, increase or decrease either the OCPUs or the storage capacity.

No.# correct Answer : ACD

No.# Aless,
SQL Developer can be started from the ADB Cloud console for import/export not only for import scenario.
D is also correct, see https://docs.oracle.com/en/cloud/paas/autonomous-data-warehouse-cloud/user/migrating.html#GUID-0870DE62-AB2D-4F41-9D54-53632DDF5B43.

for me, ABD are correct !

No.# Correct Should be "A"

How does Oracle Autonomous Database provide data security?

Oracle Autonomous Database protects against both external attacks and malicious internal users:

All data is encrypted at rest using transparent data encryption.Network connections from clients to ADB are also encrypted using the client credentials wallet. Using client credential wallets includes both server and client-side authentication and provides the highest level of security.

Oracle automatically applies all security updates to ensure data is not vulnerable.

Customers are not given OS logons or SYSDBA privileges to prevent phishing attacking.

Additional in-database features such as Database Valut, Virtual Private Database and Data Redaction are also available.
Is Data Redaction available with Oracle Autonomous Database?

Yes, data redaction is part of ADB.

https://www.oracle.com/database/technologies/datawarehouse-bigdata/adb-faqs.html

No.# The correct answer: A

https://www.oracle.com/database/technologies/datawarehouse-bigdata/adb-faqs.html#SECURITY-BOOKMARK

No.# A is correct - see https://www.oracle.com/database/technologies/datawarehouse-bigdata/adb-faqs.html#SECURITY-BOOKMARK

No.# A is wrong, B is correct.
"In autonomous database, no logins are allowed to the OS. No root or SYSDBA logins are allowed. The only allowed logins are as admin, privileged default autonomous database user, or regular database user."

No.# bce is correct

No.# It is ACE

No.# Answer should be B. C. D

No.# Correct answer in A both Data redaction and TDE are available

ref: https://www.oracle.com/database/technologies/datawarehouse-bigdata/adb-faqs.html

No.# Correct answer is B,C and D

Option A is incorrect as OS logons are not granted with autonomous database

No.# Correct answer is
B. OCPUs and storage can be scaled independently.


A. Increasing OCPUs will automatically increase storage. : OCPU and Storage are not related. OCPU is increased when more processing power is needed. that doesnt not necessarily require the storage increase

C. OCPUs and storage must remain in sync. : Again as explained for point A, storage can have its own requirement to increase irrespective of the processing power

D. Storage in TB cannot be larger than the number of OCPUs.: this is not true either

No.# Correct answers are
A. Database Upgrades
C. Backups
D. Firmware Patching

Option B is not correct as data loading is altogether a separate activity .
Option E is again not part of a default database hence not created automatically

No.# Correct answer is A

Both Data Redaction and TDE are supported.

Also validate it from your source of questions
https://www.prepawayexam.com/demo/1Z0-931.pdf

No.# Correct answers are A and C

C. Fault domains can not spread across regions.
D. Regions are independent of other regions and no such kilometre rules appies on them

No.# Data loading isnt automatic! Firmware patching stays with oracle and hence A,C and D are correct

No.# The correct answer is B,C,D

Let's see how to start and stop and scale an Autonomous Database. The Autonomous Database Instance can be scaled on demand without tedious, manual steps. Autonomous Database allows for independently scaling of compute or storage, resizing occurs instantly, fully online, memory IO bandwidth concurrency scales linearly with CPU, so when CPUs are scaled, the system automatically adjusts other resources to match, stopping an instance on demand to conserve resources, starting an instance on demand. Starting, stopping, and scaling can be done by clicking through the console. See examples in the following slides or through API calls, such as will be covered in the next module.

To scale the Autonomous Database from the console, select the database to be scaled. This will place you in the database console. Select scale up or down button. The scaling window appears. In the CPU count box, enter the number of CPUs you want provisioned in your environment. The default entry has the current value of CPUs provisioned on the environment. In this case, there is one CPU provisioned. So, in this example, we scaled the database up to four CPUs.

You can also scale the storage in terabytes of database space allocated by updating the storage parameter. When the parameters are updated, select Update. And you will be placed back on the database console where the database will show as Scaling in Progress. Please notice that the color of the database icon remains green because database scaling operations do not require system outages. When the scaling is complete, the status will change to Available, and the CPU core count will be updated to the selected CPU account during the scaling process.

No.# To connect to Autonomous Data Warehouse through an HTTPS proxy, open and update your tnsnames.ora file. Add the HTTP proxy hostname(https_proxy) and port (https_proxy_port) to the connection string. Replace the values with your HTTPS proxy information.

No.# A is correct because:

When downloading the wallet, a password must be provided so that some encrypted communication between the clients and the database can use a password as additional security. Make sure you remember this password. Please note, this password is not the same as the database user or admin password or your Oracle Cloud user account. The same password could be specified, but they are stored and used differently. After specifying the password, click on the Download button. Make sure you know the location where your wallet was downloaded. Store credential files in a secure location and share the files only with the authorized users to prevent unauthorized access to the database.
