問題1
Which statement is true about DB Systems?

A. You cannot manage the database as sys/sysdba.

B. Data Guard as a Service is offered between regions.

C. You have full control over the automatic backup schedule and retention periods.

D. You can manage Oracle database initialization parameters at a global level.

正確答案: A,C

問題2
You are in the process of setting up a highly available student registration website on Oracle Cloud Infrastructure (OCI). You use a load balancer and a database service on OCI. You launch two compute instances each in a different subnet and add them to the back end set of a public load balancer. The load balancer is configured correctly and working. You then deploy the student registration application on these two compute instances. The application can communicate with the database service. However, when you type the URL of this student registration application in your browser, no web page appears.
What could be the cause?

A. The Dynamic Routing Gateway is preventing the client traffic from your data center network from reaching the public IP of the load balancer.

B. The client requested https access to the application and the load balancer service does not support end-to-end SSL from the client to the listener to the back-end set.

C. The load balancer performed a health check on the application and found that compute instances were not in a healthy state and terminated the instances.

D. The security lists of the subnets on which the two instances are located do not have "allow" rules for port 80 and 443.

正確答案: D

問題3
You are an administrator with an application running in Oracle Cloud Infrastructure (OCI). The company has a fleet of OCI compute virtual instances behind an load balancer. The load balancer backend set health check API is providing a 'Critical' level warning. You have confirmed that your application Is running healthy on the backend servers. What Is the possible reason for this
'Critical' warning?

A. The security list associated with the subnet In which the backend server is provisioned does not include the IP range for the source of the health check requests.

B. The load balancer listener is not configured correctly.

C. A user does not have correct Identity and Access Management (IAM) credentials on the backend servers.

D. The route table associated with the subnet in which the backend server is provisioned does not include the route for the OCI load balancer.

正確答案: A

問題4
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. The route table associated with subnets in each VCN do not have a route rule defined to forward the traffic to their respective DRGs

B. The security lists associated with subnets in each virtual cloud network (VCN) do not have the appropriate ingress rules

C. Identity and Access Management (IAM) policies have not been defined to allow connectivity across the two VCNs in different regions

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. 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

正確答案: A,B

問題5
Your application front end consists of several Oracle Cloud Infrastructure compute instances behind a load balancer. You have configured the load balancer to perform health checks on these instances. If an instance fails to pass the configured health checks, what will happen?

A. The load balancer stops sending traffic to that instance.

B. The instance is taken out of the back end set by the load balancer.

C. The instance is terminated automatically by the load balancer.

D. The instance is replaced automatically by the load balancer.

正確答案: A

問題6
Your company is developing a new database application in Oracle Cloud Infrastructure. You need to test application functionality including a hardware failure scenario. Since the application is still in the development phase, you want to minimize infrastructure costs. Which database service deployment option meets this requirement?

A. Autonomous Data Warehouse (ADW) system as it provides auto fail over functionality

B. single node bare metal system

C. two node bare metal system with data guard enabled

D. two node real application cluster (RAC) system

正確答案: D

問題7
You are designing a high bandwidth, redundant connection between your data center and Oracle Cloud Infrastructure (OCI). While researching for OCI FastConnect locations, you notice that you are co-located with Oracle at one of the Oracle FastConnect locations in the Ashburn region.
What is the recommended design in this scenario?

A. Create a cross-connect group and have at least two or more cross-connects in that group. Create at least two or more virtual circuits in the group.

B. Create a cross-connect group and have at least one cross-connect in that group. Create at least one virtual circuit in the group.

C. Setup two IPsec connections between your data center and OCI Ashburn region. Create a OCI load balancer to distribute the traffic across the two connections.

D. Create a cross-connect group and have two or more cross-connects in that group. Create an IPsec VPN connection on this group.

正確答案: A

問題8
Which two actions will occur when a back-end server that is registered with a backend set is marked to drain connections? (Choose two.)

A. It forcibly closes all connections to that instance after a timeout period.

B. It redirects the requests to a user-defined error page.

C. It keeps the connections to that instance open and attempts to complete any in-flight requests.

D. It immediately closes all existing connections to that instance.

E. It disallows new connections to that backend server.

正確答案: C,E
