문제3
You create an autoscaling configuration of Linux compute instances in Oracle Cloud Infrastructure (OCI).
You noticed that your application is running slow.
After checking your compute instances, you noticed that autoscaling is not launching additional instances, even though the existing compute instances already have high memory usage.
How can you resolve this issue?

A. Install OCI SDK in all compute instances and create a script that will trigger theautoscaling event if there is high memory usage.

B. Install the monitoring agent to all compute instances which will trigger the autoscaling group.

C. Modify the scaling policy to monitor CPU usageand scale up the number of instances when it meets the threshold.

D. Modify the scaling policy to monitor memory usage and scale up the number of instances when it meets the threshold.

정답: C

문제4
You have launched a compute instance runningOracle 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. Use the default Security List, which has ports open for OCI Object Storage

B. 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

C. Add a stateful rule that enables ingress HTTPS (TOP port 443) traffic to 001 Object Storage in the securitylist associated with the private subnet

D. 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.'

문제6
You want an instance in your compartment to make API calls to other services within Oracle Cloud Infrastructure without storing credentials in a configuration file.
What do you need to do?

A. Instances cannot access services outside their compartment.

B. VM instances are treated as users. Create a user and assign the user to that VM instance.

C. No action is required. By default, all VMinstances are created with an Instance Principal.

D. Create appropriate matching rules in the Dynamic Group to create an Instance Principal.

문제7
You have created a new compartment called Production to host some production apps. You have also created users in your tenancy and added them to a Group called "production group". Your users are still unable to access the Production compartment. How can you resolve this situation?

A. Write an IAM Policy for each specific user granting them access to the production compartment

B. Write an IAM Policy for "production_group" granting it access to the production compartment

C. Every compartment you create comes with a predefined set of policies, so no further action is needed

D. Your users get automatic access to all compartments, so no further action is needed

문제8
You have created a virtual cloudnetwork (VCN) with three private subnets. Two of the subnets contain application servers and the third subnet contains a DB System. The application requires a shared file system so you have provisioned one using the file storage service (FSS). You also created the corresponding mount target in one of the application subnets. The VCN security lists are properly configured so that both application servers and the DB System can access the file system. The security team determines that the DB System should haveread-only access to the file system.
What change would you make to satisfy this requirement?

A. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.

B. Connect via SSH to one of the application servers where the file system has been mounted. Use the Unix command chmod to change permissions on the file system directory, allowing the database user read only access.

C. Create an instance principal for the DB System. Write an Identity and Access Management (IAM) policy that allows the instance principal read-only access to the filestorage service.

D. Modify the security list associated with the subnet where the mount target resides. Change the ingress rules corresponding to the DB System subnet to be stateless.

문제9
You are deploying a highly available web application in OracleCloud Infrastructure and have decided to use a public load balancer. The back-end web servers will be distributed across all three availability domains (ADs).
How many subnets should you create to deliver a secure highly available application?

A. three subnets in total; one subnet in each AD

B. foursubnets in total; one subnet in each AD for the web servers and a single subnet in any one AD for the load balancer

C. five subnets in total; two subnets each in the first and second AD with a single subnet in the third AD

D. six subnets in total; two subnets in each AD; one for the load balancer and one for the web servers

정답: D

문제10
You have provisioned an Autonomous Transaction Processing (ATP) database and logged into the ATP service console.
What are three abilities that can be performed from this service console? (Choose three.)

A. scale up/down the CPUs

B. create ATP database users

C. monitor database activity and SQL queries

D. reset the admin password

E. set resource management rules

정답: C,D,E

문제11
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. The Backend Server VCN's Route Table does not include the route for OCI LB.

B. A user does not have correct IAM credentials on theBackend Servers.

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

D. OCI Load Balancer Listener is not configured correctly.

문제12
Yourapplication front end consists of several Oracle Cloud Infrastructure compute instances behind a public load balancer. You have configured the load balancer to perform health checks on these instances.
What will happen if an instance fails to pass the configured health checks?

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

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

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

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

문제13
You are designing a networking infrastructure in multiple Oracle Cloud Infrastructure regionsand 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. 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

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