Question 51

Which three load-balancing policies can be used with a back end set? (Choose three.)

A.Throughput

B.IP Hash

C.Weighted Round Robin

D.CPU Utilization

E.Least Connections

Question 52

Which statement is true about DB Systems?

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

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

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

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

Question 53

You are an administrator with an application running on OCI. The company has a fleet of OCI compute virtual instances behind an OCI Load Balancer. The OCI Load Balancer Backend Sethealth 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.A user does not have correct IAM credentials on theBackend Servers.

B.The Backend Server VCN's Route Table does not include the route for OCI LB.

C.OCI Load Balancer Listener is not configured correctly.

D.The Backend Server VCN's Security List does not include the IP range for the source of the healthcheck requests.

Question 54

Within your tenancy you have a compute instance with a boot volume and a block volume attached. The boot volume contains the OS and the attached block volume contains the instance's important data. Logs on the boot volume have filled the boot volume and are causing issues with the OS.
What should you do to resolve this situation?

A.Stop the instance that is full. Create a manual backup of the block storage before making changes.
Detach the block volume, create a new instance ofthe same shape with a larger custom boot volume and attach the block volume to the new instance. Configure the OS and any related application(s) to access the block volume under the same mount point as before.

B.Create a new instance with a larger boot volume size as well a new block volume which is the same size or larger than the one attached to the full instance. rsync the state of the boot volume and the state of the block volume between the two instances.

C.Detach the block volume from the full instance. Create a new instance of the same shape with a larger boot volume and rsync the state of the boot volume between the instances. Attach the block volume to the new instance.

D.Create a manual backup of the block storage instance. Create a custom imageof the full instance. Once that completes deploy the custom image to a new instance.

Question 55

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

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 balancerperformed a health check on the application and found that compute instances were not in a healthy state and terminated the instances.

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