Exam 1z0-932 topic 1 question 156 discussion

B and D is the right answer. I saw it in the practice set

A is correct : If your primary and standby databases are in the same region, then both must use the same virtual cloud network (VCN). If your primary and standby databases are in different regions, then you must peer the virtual cloud networks (VCNs) for each database. See Remote VCN Peering using an RPC. B is wrong because ; This is only applicable to Bare Metal and Virtual Machine DB systems. C is correct - An Oracle Data Guard implementation requires two DB systems, one containing the primary database and one containing the standby database. When you enable Oracle Data Guard for a virtual machine DB system database, a new DB system with the standby database is created and associated with the primary database. For a bare metal DB system, the DB system with the database that you want to use as the standby must already exist before you enable Oracle Data Guard.

B) “An Oracle Data Guard implementation requires two DB systems, one containing the primary database and one containing the standby database. ” D) “The egress rules in the example show how to enable TCP traffic only for port 1521, which is a minimum requirement for Oracle Data Guard to work. “ https://docs.cloud.oracle.com/en-us/iaas/Content/Database/Tasks/usingdataguard.htm NOT A, NOT C) “This procedure is only applicable to bare metal and virtual machine DB systems. ”

A. Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal B. Data guard configuration on the OCI is limited to one standby database per primary database C. Data guard configuration on the OCI is limited to a virtual machine only D. Data guard implementation requires two DB Systems, one containing the primary database and one containing the standby database
