Question 6

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.Add a new route rule to the private subnet route table to route default traffic to the internet gateway.

B.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.

C.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.

D.Create a service gateway, add a new route rule to the private subnet route table that uses object storage as target type.

Question 7

You need to set up instance principals so that an application running on an instance can call Oracle Cloud Infrastructure (OCI) public services, without the need to configure user credentials.
A developer in your team has already configured the application built using an OCI SDK to authenticate using the instance principals provider.
Which is NOT a necessary step to complete this set up?

A.Create a dynamic group with matching rules to specify which instances you want to allow to make API calls against services.

B.Generate Auth Tokens to enable instances in the dynamic group to authenticate with APIs.

C.Create a policy granting permissions to the dynamic group to access services in your compartment or tenancy.

D.Deploy the application and the SDK to all the instances that belong to the dynamic group.

Question 8

Which two statements are true about data guard service on DB Systems in Oracle Cloud Infrastructure (OCI)?

A.Data guard implementation requires two DB Systems, one containing the primary database and one containing the standby database.

B.Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal.

C.Both DB Systems must use the same VCN, and port 1521 must be open.

D.Data guard configuration on the OCI is limited to a virtual machine only.

Question 9

With regard to Oracle Cloud Infrastructure Load Balancing service, which two actions will occur when a backend server that is registered with a backend set is marked to drain connections? (Choose two.)

A.All connections to this backend server are forcibly closed after a timeout period.

B.Requests to this backend server are redirected to a user-defined error page.

C.All existing connections to this backend sever will be immediately closed.

D.All new connections to this backend server are disallowed.

E.Connections to this backend server will remain open until all in-flight requests are completed.

Question 10

Which DNS resource record type is used to point a host name to an IPv4 address?

A.ALIAS

B.A

C.CNAME

D.AAAA
