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.)
- A. 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.

質問 # 27
Multiple teams are sharing a tenancy in OracleCloud Infrastructure (OCI). You are asked to figure out an appropriate method to manage OCI costs.
Which is NOT a valid technique to accurately attribute costs to resources used by each team? (Choose the best answer.)
- A. Create separate compartment for each team. Use the OCI cost analysis tools to filter costs by compartment.
- B. Create an Identity and Access Management (IAM) group for each team. Create an OCI budget for each group to track spending.
- C. Create a Cost-Tracking tag. Apply this tag to all resources with team information. Use the OCI cost analysis tools to filter costs by tags.

質問 # 29
What is a key benefit of using Oracle Cloud Infrastructure's Resource Manager for your Terraform provisioning and management activities? (Choose the best answer.)
- A. Resource Manager has administrative privileges by design. Even if your IAM user does not have access, you can leverage Resource Manager to provision new resources to any compartment in the Tenancy.
- B. You can useResource Manager to apply patches to all existing Oracle Linux interfaces in a specified compartment.
- C. Resource Manager manages to Terraform state file for your infrastructure andlocks the file so that only one job at a time can run on a given stack.
- D. You can use Resource Manager to identify and maintain an inventory of all Compute and Database instances across your tenancy.
正解：C
解説：
Explanation
https://docs.oracle.com/en-us/iaas/Content/ResourceManager/Concepts/resourcemanager.htm A Terraform configuration codifies your infrastructure in declarative configuration files. Resource Manager allows you to share and manage infrastructure configurations and state files across multiple teams and platforms. This infrastructure management can't be done with local Terraform installations and Oracle Terraform modules alone. For more information about the Oracle Cloud Infrastructure Terraform provider, see Terraform Provider.
質問 # 30
You have recently joined a startup company and quickly find that nobody is tracking the amount of money spent on Oracle Cloud Infrastructure (OCI). Seeing an opportunity to help save money you begin creating a solution tobetter track the cost of resources provisioned by each individual on the team.
Which option allows you to identify excessive spend across all resources in your tenancy? (Choose the best answer.)
- A. Use the Python SDK to write a custom application thatwill monitor the Audit log. Look for CREATE events and configure the application to send you an email each time a new resource is created.
- B. Create a tag namespace named BILLING with a Tag Key named CostCenter. Tag each of your resources with this Tag Keyand the correct value.
- C. Create a budget for each compartment that will send a notification when monthly spend reaches a pre- defined amount.
- D. Use the Events Service and create rules that will act when a new Object Storage bucket or Compute Instance has been created. Have the rule email you each time one of these events occurs.

質問 # 32
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.)
- A. User is connecting as the default Oracle Linux user 'opc' instead of 'root' user.
- B. 'touch' command is not available in Oracle Linux by default.
- C. Service limits or quota for file system writes have been breached.
- D. Useris not part of any OCI Identity and Access Management group with write permissions to File Storage service.
正解：A
解説：
Explanation
https://docs.oracle.com/en-us/iaas/Content/File/Troubleshooting/cannotwrite.htm When a file system is created, the root user owns the root directory. If you're connecting from an instance that uses a Linux orCentOS platform image, the default user is opc. The default user is ubuntu when you connect from an instance that uses an Ubuntu platform image. These default users are not root users, so you can't initially write a file or directory to a new file system with these users.

Explanation
"File Storage performance increases with parallelism. Increase concurrency by using multiple threads, multiple clients, and multiple mount targets."
質問 # 36
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.)
- A. Advertise a 192.168.10.10/32 router over the FastConnect.
- B. The instances will communicate by default over the FastConnect private virtual circuit, which ensures data is encrypted in-transit.

質問 # 39
You launched a Linux compute instance to host the new version of your company website via Apache Httpd server on HTTPS (port 443). The instance is created in a public subnet along with other instances. The default security list associated to the subnet is:
You want to allow access to the company website from public internet without exposing websites eventually hosted on the other instances in the public subnet.
Which actionwould you take to accomplish the task? (Choose the best answer.)
- A. Create a network security group, add a stateful rule to allow ingressaccess on port 443 and associate it to the instance that hosts the company website.
- B. In default security list,add a stateful rule to allow ingress access on port 443.
- C. Create a new security list with a stateful rule to allow ingress access on port 443 and associate it to the public subnet.
- D. Create a network security group, add a stateful rule to allow ingress access on port 443 and associate it to the public subnet that hosts the company website.
正解：A
解説：
Explanation
Since we want to avoid exposing other instances in the same public subnet to the internet, Network Security Groups (NSG) must be used instead of Security Lists. NSG are attached to the vnic of the instance and not to the subnet
