1 Secure Cluster Communication protects the cluster interconnect from common security threats when used together with Single Network Support. Secure Cluster Communication includes message digest mechanisms, protection against fuzzing, and uses Transport Layer Security (TLS) to provide privacy and data integrity between the cluster members. Which statement is true about securing cluster interconnect communication?

A Security for the cluster interconnect is invoked automatically as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c and Database administrators or cluster administrators do not need to make any configuration changes for this feature.

B Security for the cluster interconnect is invoked automatically as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c using an auto- generated encryption key that is stored locally on each node of the cluster in an Oracle Wallet and Database administrators or cluster administrators must provide a valid path for the Wallet file.

C Security for the cluster interconnect is invoked by auto-generated server certificates that will be assigned to each cluster node as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c.

D Database administrators or cluster administrators must provide an encryption key during new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c to secure the interconnect communication.

E Database administrators or cluster administrators must provide a valid server certificate and an Oracle Wallet for each node during new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c to secure the interconnect communication.

Answer: A

The correct answer is A. Oracle Grid Infrastructure 19c includes Secure Cluster Communication for the cluster interconnect as a built-in capability when used with Single Network Support. This means the feature is enabled automatically during: - a new Oracle Grid Infrastructure 19c installation, or - an upgrade to Oracle Grid Infrastructure 19c No manual configuration is required from database administrators or cluster administrators to turn it on. Why A is correct: - The protection is automatic. - It does not require administrators to create or manage encryption keys. - It does not require providing certificates or Wallet files. - Oracle handles the security setup as part of the GI deployment or upgrade process. Why the other options are incorrect: B is incorrect: - It claims an auto-generated encryption key is stored in an Oracle Wallet and that administrators must provide a Wallet path. - Secure Cluster Communication does not require DBA/cluster admin intervention for wallet configuration in this context. C is incorrect: - It says auto-generated server certificates are assigned to each cluster node. - The feature is not described as relying on node-specific server certificates in this way. D is incorrect: - It says administrators must provide an encryption key. - This is false because the feature is automatic and does not require manual key provisioning. E is incorrect: - It says administrators must provide a server certificate and Oracle Wallet for each node. - This is also false because the feature is enabled automatically without that manual setup. In short: Secure Cluster Communication in Oracle Grid Infrastructure 19c is automatically enabled during installation or upgrade, so no extra configuration is needed.

2 Examine this command: SQL> CREATE PLUGGABLE DATABASE pdb3 FROM pdb1; Which three conditions must be true for successful execution of this command on a RAC database? (Choose three.)

A The source PD3 must be closed on the CDS instance from where the command is executed.

B The source PD3 must be in read only mode on all CD3 instances if the CDB is in No Archive mode.

C The source pdb must use a global temporary

D It can be executed only by a common user with the create pluggable database system privilege connected to the root container.

E Oracle Managed Files must be enabled or PD3 file name convert must be set.

F All running CDB instances must be open in restricted mode.

Answer: A, D, E

The correct answers are A, D, and E. The command SQL> CREATE PLUGGABLE DATABASE pdb3 FROM pdb1; is a clone operation that creates a new pluggable database from an existing one. In a RAC environment, there are extra requirements because multiple instances may be open and accessing the container database. Why A is correct: The source pluggable database must be closed on the instance from which the command is issued. For cloning a PDB in RAC, Oracle requires the source PDB to be closed in the current instance so the clone can be created consistently from its files. This avoids file access conflicts during the operation. Why D is correct: The command must be executed by a common user connected to the root container who has the CREATE PLUGGABLE DATABASE system privilege. Creating a PDB is a container-level administrative task. In a multitenant environment, such operations are performed from CDB$ROOT by a common user with the appropriate privilege. Why E is correct: Oracle Managed Files must be enabled or the PDB_FILE_NAME_CONVERT parameter must be set. When creating a PDB from another PDB, Oracle needs to know where to place the new PDB’s datafiles. Either Oracle Managed Files handles file placement automatically, or file name conversion must be configured so the source file names can be mapped to new ones. Why the other options are incorrect: B. The source PDB must be in read only mode on all CDB instances if the CDB is in No Archive mode. This is not a requirement for this command as stated. The condition mixes concepts incorrectly and is not one of the RAC requirements for cloning a PDB. C. The source PDB must use a global temporary database. This is not relevant to creating a PDB from another PDB. Global temporary tables have nothing to do with the clone operation requirements. F. All running CDB instances must be open in restricted mode. This is unnecessary. The CDB instances do not all need to be in restricted mode for this command to succeed. Summary: To successfully run CREATE PLUGGABLE DATABASE pdb3 FROM pdb1 in RAC, you need: - the source PDB closed on the instance where the command runs, - a common user in root with CREATE PLUGGABLE DATABASE privilege, - and either Oracle Managed Files enabled or PDB file name conversion configured. So the correct choice is A, D, and E.

What are the main topics in 1Z0-078

The Oracle 1Z0-078 exam reaches beyond one tool, and it checks daily administration, tuning, and recovery.

RAC databases and architecture. You should know why Oracle RAC uses global resources and how global cache coordination works.
