1Z0-160 Online Practice Questions and Answers

Correct Answer: C

Explanation:

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 node's 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.

Correct Answer: AC

Explanation:

You can migrate Oracle Database 12c non-CDB databases from on-premises to Oracle Database 12c

databases in Oracle Database Cloud using several different methods including:

*

Data Pump Conventional Export/Import This method can be used regardless of the endian format and database character set of the on-premises database.

*

Remote Cloning (non-CDB)

This method can be used only if the on-premises platform is little endian, the on-premises database release is 12.1.0.2 or higher, and the on-premises database and Database Cloud Service database have compatible database character sets and national character sets.

You can use the remote cloning method to copy an Oracle Database 12c non-CDB on-premises database to your Oracle Database 12c database in the cloud.

*

RMAN CONVERT Transportable Tablespace with Data Pump This method can be used only if the database character sets of your on-premises database and Oracle Database Cloud Service database are compatible.

*

RMAN Cross-Platform Transportable Tablespace Backup Sets

This method can be used only if the database character sets of your on-premises database and Oracle Database Cloud Service database are compatible.

Correct Answer: C

Explanation:

To generate an SSH key pair on UNIX and UNIX-like platforms using the ssh-keygen utility:

1.

Navigate to your home directory:

$ cd $HOME

2.

Run the ssh-keygen utility, providing as filename your choice of file name for the private key:

$ ssh-keygen -b 2048 -t rsa -f filename

The ssh-keygen utility prompts you for a passphrase for the private key.

3.

Enter a passphrase for the private key, or press Enter to create a private key without a passphrase Etc.

Correct Answer: B

Explanation:

The Data Pump Transportable Tablespace can be used only if the on-premises platform is little endian,

and the database character sets of your on-premises database and Oracle Database Cloud Service

database are compatible.

The Transportable Tablespace method is generally much faster than a conventional export/import of the same data because the data files containing all of the actual data are simply copied to the destination location.

Incorrect Answers:

C: Data Pump TDB is not supported in this scenario.

D: The data pump conventional export/import method is simple to implement, provides the broadest cross-platform support and enables you to physically re-organize your target database; however, the time and resources required for export and import may rule out this approach for situations with large databases or limited timeframes.

E: Remote cloning is not supported in this scenario.
