質問 2：
You have created a virtual cloud network (VCN) with three private subnets. Two of the subnets contain application servers and the third subnet contains a DB System. The application requires a shared file system so you have provisioned one using the file storage service (FSS). You also created the corresponding mount target in one of the application subnets. The VCN security lists are properly configured so that both application servers and the DB System can access the file system. The security team determines that the DB System should have read-only access to the file system. What change would you make to satisfy this requirement?
A. Connect via SSH to one of the application servers where the file system has been mounted. Use the Unix command chmod to change permissions on the file system directory, allowing the database user read only access.
B. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.
C. Modify the security list associated with the subnet where the mount target resides. Change the ingress rules corresponding to the DB System subnet to be stateless.
D. Create an instance principal for the DB System. Write an Identity and Access Management (IAM) policy that allows the instance principal read-only access to the file storage service.

質問 4：
Which two statements are true about Oracle Cloud Infrastructure (OCI) DB Systems Data Guard service?
A. Data guard implementation for Bare Metal shapes requires two DB Systems, one containing the primary database and one containing the standby database.
B. Data guard configuration on the OCI is limited to a virtual machine only
C. Both DB systems must use the same VCN, and port 1521 must be open
D. Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal.

A. It is not possible to create pre-authenticated requests for the buckets, but only for the objects
B. It Is not possible to create pre-authenticated requests for "archive" storage tier
C. Changing the bucket visibility does not change existing pre-authenticated requests
D. Pre-authenticated requests don't have an expiration

質問 6：
You are designing a networking infrastructure in multiple Oracle Cloud Infrastructure regions and require connectivity between workloads in each region. You have created a dynamic routing gateway (DRG) and a remote peering connection. However, your workloads are unable to communicate with each other.
What are two reasons for this? (Choose two.)
A. Identity and Access Management (IAM) policies have not been defined to allow connectivity across the two VCNs in different regions
B. The security lists associated with subnets in each virtual cloud network (VCN) do not have the appropriate ingress rules
C. An Internet gateway needs to be created in each VCN with a default route rule added in the route table forwarding the traffic to the Internet Gateway
D. A local peering gateway needs to be created in each VCN with a default route rule added in the route table forwarding the traffic to the local peering gateway
E. The route table associated with subnets in each VCN do not have a route rule defined to forward the traffic to their respective DRGs
正解：B,E

Which statement is true about Data Guard Implementation in DB systems?
A. You cannot manage the database as sys/sysdba.
B. Both DB systems must be in the same compartment, and they must be the same shape
C. You cannot manage Oracle database initialization parameters at a global level.
D. You can define the backup window and set custom backup retention period for the automatic database backup schedule.
