NEW QUESTION 120
You have launched a compute instance running Oracle database in a private subnet in the Oracle Cloud Infrastructure US East region. You have also created a Service Gateway to back up the data files to OCI Object Storage in the same region. You have modified the security list associated with the private subnet to allow traffic to the Service Gateway, but your instance still cannot access OCI Object Storage. How can you resolve this issue?
- A. Add a stateful rule that enables ingress HTTPS (TOP port 443) traffic to 001 Object Storage in the security list associated with the private subnet
- B. Add a rule in the Route Table associated with the private subnet with Target type as "Service Gateway" and destination service as all IAD services in the Oracle Service Network.'
- C. Use the default Security List, which has ports open for OCI Object Storage
- D. Add a stateful rule that enables egress HTTPS (TCP port 443) traffic to OCI Object Storage in the security list associated with the private subnet
Answer: B
Explanation:
Explanation
A service gateway lets your virtual cloud network (VCN) privately access specific Oracle services without exposing the data to the public internet. No internet gateway or NAT is required to reach those specific services. The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the Oracle service travels over the Oracle network fabric and never traverses the internet.
The service gateway is regional and enables access only to supported Oracle services in the same region as the VCN.
For traffic to be routed from a subnet in your VCN to a service gateway, you must add a rule accordingly to the subnet's route table. The rule must use the service gateway as the target. For the destination, you must use the service CIDR label that is enabled for the service gateway. This means that you don't have to know the specific public CIDRs, which could change over time.

NEW QUESTION 131
You are a network architect and have designed the network infrastructure of a three-tier application on Oracle Cloud Infrastructure (OCI). In the architecture, back-end DB servers are in a private subnet. One of your DB administrators requests to have access to OCI object storage service.
How can you meet this requirement?
- A. Create a service gateway, add a new route rule to the private subnet route table that uses object storage as target type.
- B. Create a dynamic routing gateway (DRG) and attach it to your virtual cloud network (VCN). Add a default route rule to the private subnets route table and set the target as DRG.
- C. Attach a public IP address to the instances in the private subnet, and then add a new route rule to the private subnet route table to route default traffic to the internet gateway.
- D. Add a new route rule to the private subnet route table to route default traffic to the internet gateway.
Answer: A
Explanation:
A service gateway lets resources in your VCN privately access specific Oracle services, without exposing the data to an internet gateway or NAT. The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the service of interest travels over the Oracle network fabric and never traverses the internet.
To give your VCN access to a given service CIDR label, you must enable that service CIDR label for the VCN's service gateway. You can do that when you create the service gateway, or later after it's created. You can also disable a service CIDR label for the service gateway at any time.
For traffic to be routed from a subnet in your VCN to a service gateway, you must add a rule accordingly to the subnet's route table. The rule must use the service gateway as the target.

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.
Answer: B
Explanation:
Explanation
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.
Requirement details are as follows:
- Both DB systems must be in the same compartment.
- The DB systems must be the same shape type (for example, if the shape of the primary database is a virtual machine, then the shape of the standby database can be any other virtual machine shape).
- 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 (Across Regions).
- Configure the security list ingress and egress rules for the subnets of both DB systems in the Oracle Data Guard association to enable TCP traffic to move between the applicable ports. Ensure that the rules you create are stateful (the default).
