All data is encrypted at rest. and In-transit encryption provides a way to secure your data between instances and mounted file systems using TLS v. 1.2 (Transport Layer Security) encryption.
File Storage service supports the AUTH_UNIX style of authentication and permission checking for remote NFS client requests.
NEW QUESTION 90
You have successfully configured identity federation between Oracle Cloud Infrastructure (OCI) and Oracle Identity Cloud Services (IDCS). A new project manager wants access to OCI for her team and provides the name of an existing group within IDCS to use when granting access.
How do you configure federation to allow the project team access to OCI resources?
- A. Create a new IAM group in OCI and map it to the existing IDCS group. Create a new policy in IDCS and reference the name of the IAM group.
- B. Create a new Identity and Access Management (IAM) policy in OCI and reference the name of the IDCS group in each policy statement.
- C. Create a new compartment in OCI with the same name as the existing IDCS group. Create an IAM policy that references the new compartment and the name of the IDCS group.
- D. Create a new IAM group in OCI and map it to the existing IDCS group. Create a new IAM policy and reference the name of the IAM group in each policy statement.
Answer: D
Explanation:
Explanation
When working with your IdP, your administrator defines groups and assigns each user to one or more groups according to the type of access the user needs. Oracle Cloud Infrastructure also uses the concept of groups (in conjunction with IAM policies) to define the type of access a user has. As part of setting up the relationship with the IdP, your administrator can map each IdP group to a similarly defined IAM group, so that your company can re-use the IdP group definitions when authorizing user access to Oracle Cloud Infrastructure resources. Here's a screenshot from the mapping process:
NEW QUESTION 91
You are implementing Oracle Cloud Infrastructure (OCI) FastConnect to access OCI public access points (e.g.
- object storage). You want other Internet traffic from your on-premises environment to use your existing connection with your ISP.
What is the correct way to establish OCI FastConnect to access these OCI public endpoints?
- A. Configure private peering on your FastConnect link. Redistribute BGP routes learned into your existing routing table and advertise a default from your network infrastructure to OCI.
- B. Configure public peering on your FastConnect link. Redistribute BGP routes learned into your existing routing table and advertise a specific route for your network infrastructure to OCI.
- C. Configure public peering on your FastConnect link with a static route that points to OCI object storage service.
- D. Configure private peering on your FastConnect link with a static route that points to OCI object storage service.

NEW QUESTION 93
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. Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal.
- D. Both DB systems must use the same VCN, and port 1521 must be open
Answer: A,D
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.
- 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).
NEW QUESTION 94

- B. The HIGH consumer group can run up to 16 concurrent SQL statements in addition to 32 concurrent SQL statements in MEDIUM and LOW consumer group each
- C. The HIGH consumer group can run up to 16 concurrent SQL statements as long as MEDIUM and LOW consumer groups have 0 SQL statements
- D. The HIGH consumer group can run 3 concurrent SQL statements when MEDIUM consumer group has
0 SQL statements - E. The MEDIUM consumer group can run 20 concurrent SQL statements when HIGH consumer group has

- A. Each availability domain contains three fault domains
- B. A failed instance in a fault domain is automatically relaunched
- C. A fault domain is selected automatically based on usage data
- D. A fault domain is a grouping of hardware and infrastructure within an availability domain
Answer: A,D
Explanation:
Explanation
References:
A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain.
