QUESTION 29
A subscriber of an Oracle Cloud Infrastructure (OCI) Notifications service topic complained about not receiving messages from the service.
Which optioncan help you debug this issue? (Choose the best answer.)

If OCI Notifications service does not receive an acknowledgement from a subscription endpoint, the service drops the message. Confirm that the subscriber is always online to receive messages to help debug the issue.

If OCI Notifications service does not receive an acknowledgement from a subscription endpoint, check the NumberOfNotificationFailed metric through the OCI Monitoring service for failed messages. Copy these messages to an OCI ObjectStorage bucket. Make sure the subscriber has the required credentials to access this bucket to help debug the issue.

If OCI Notifications service does not receive an acknowledgement from a subscription endpoint, the service tries to redeliver messages for up to one day. Make sure that the subscriber is online at least once a day to help debug the issue.

If OCI Notifications service does not receive an acknowledgement from a subscription endpoint, the service tries to redeliver messages for up to two hours. Configure an alarm on the NumberOfNotificationFailed metric through the OCI Monitoring service to help debug the issue.

QUESTION 34
You have been asked to ensure that in-transit communication between an OracleCloud Infrastructure (OCI) compute instance and an on-premises server (192.168.10.10/32) is encrypted. The instances communicate using HTTP. The OCI Virtual Cloud Network (VCN) is connected to the on-premises network by two separate connections: a DynamicIPsec VPN tunnel and a FastConnect virtual circuit. No static configuration has been added.
What solution should you recommend? (Choose the best answer.)

The instances will communicate by default over IPsec VPN, which ensures data is encrypted in-transit.

Advertise a 192.168.10.10/32 route over the VPN.

Advertise a 192.168.10.10/32 router over the FastConnect.

The instances will communicate by default over the FastConnect private virtual circuit, which ensures data is encrypted in-transit.

QUESTION 35
Which two statements are TRUE about Object Storage data security and encryption in Oracle Cloud Infrastructure (OCI)? (Choose two.)

Client-side encryption is managed by the customer.

Data needs to be decrypted on the client side before retrieving it.

OCI Vault Management is used by default to provide data security.

All traffic to and from Object Storage service is encrypted using TLS.

A VPN connection to OCI is required to ensure secure data transfer to an object storage bucket.

QUESTION 36
You have been asked to review a network design for Oracle Cloud Infrastructure (OCI) by a major client. The client’s IT team needs to provision two Virtual Cloud Networks (VCNs) for a major application. The application uses a large number of virtual machine instances. Additionally, in the future, a VCN peering will be required to allow connectivity between the VCNs.
Which of the following are valid IP ranges to consider? (Choose the best answer.)

10.0.0.0/30 and 192.168.0.0/30

10.0.0.0/8 and 11.0.0.0/8

10.0.8.0/21 and 10.0.16.0/22

10.0.0.0/16 and 10.0.64.0/24

QUESTION 37
Your company hasrestructured its HR departments. As part of this change, you also need to re-organize compartments within Oracle Cloud Infrastructure (OCI) to align them to the company’s new organizational structure. The following change is required:

Compartment Team_xneeds to be moved under a new parent compartment, Project_B The tenancy has the following policies defined for compartments Project_A and Project_B: Policy1: Allow group G1 to manage instance-family in compartment HR:Project_A Policy2: Allow group G2 tomanage instance-family in compartment HR:Project_B Which two statements describe the impacts after the compartment Team_x is moved? (Choose two.)

Group G2 can now manage instance-families in compartment Project_B and compartment Team_X

Group G1 can now manage instance-families in compartment Project_A, compartment Project_B and compartment Team_X

Group G1 can now manage instance-families in compartment Project_A but not in compartment Team_x

Group G2 can now manage instance-families in compartment Project_A but not in compartment Team_x

Group G2 can now manage instance-families in compartment Project_B, compartment Project_A and compartment Team_X

QUESTION 38
Recently, your e-commerce web application has been receiving significantly more traffic than usual. Users are reporting they often encounter a 503 Service Error when trying to access your site. Sometimes the site is very slow.
You check your instance pool configuration to confirm that the maximum number of instances is configured to allow 20 compute instances. Currently, 14 compute instances have been provisioned by the instance pool.
You also confirm that current CPU utilization across all hosts exceeds the scale-out threshold you set in your auto-scaling policy. However, the instance pool is not provisioning any newinstances.
What can you check to determine why the application is NOT functioning properly? (Choose the best answer.)

Verify that the new offer feature code did not introduce any performance bugs.

Verify that the database is accessible.

Verifythat the compute resource quota has not been exceeded.

QUESTION 39
An insurance company has contracted you to help automate their application business continuity plan. They have the application running in eu-frankfurt-1 asthe primary site and uk-london-1 as a disaster recovery site.
Normally they have a DNS A record associated with the IP address of the primary endpoint in eu-frankfurt-1.
In the event of a disaster, they use OCI DNS Zone Management to update the A record and replace it with the IP address of the endpoint in uk-londond-1.
How can you automate the failover process? (Choose the best answer.)

Create a Health Check that evaluates both regional endpoints. Create a Traffic Management Steering policy with Failover type and associate it with the Health Check.

Create a Traffic Management Steering policy with Load Balancer type and add both eu-frankfurt-1 and uk- london-1 endpoints. Attach the Traffic Management Steering policy to the A record.

Provision a Load Balancer in Frankfurt and associate it with the A record in DNS. Create a backend set with backend servers from both eu-frankfurt-1 and uk-london-1 regions.

Create a Traffic Management Steering policy and attach it to a backend servers from both eu-frankfurt-1 and uk-london-1 regions.

QUESTION 40
A developer has created a file system in Oracle Cloud Infrastructure (OCI) File Storage service. She launches an Oracle Linux compute instance and successfully mounts the file system from the instance.
She then tries writing to the file system from the compute instance using the following command:
touch /mnt/yourmountpoint/helloworld
But gets an error message:
touch: cannot touch’/mnt/yourmountpoint/helloworrld’: Permission denied Which is a reason for this error? (Choose the best answer.)

‘touch’ command is not available in Oracle Linux by default.

Service limits or quota for file system writes have been breached.

Useris not part of any OCI Identity and Access Management group with write permissions to File Storage service.

User is connecting as the default Oracle Linux user ‘opc’ instead of ‘root’ user.

Enable BGP on the FastConnect that you want as the ACTIVE connection.

Use AS PATH prepending with your routes.

Adjust one of the connections to have a higher ASN.
