You are part of a project team working in the development environment created in Oracle Cloud Infrastructure (OCI). You realize that the CIDR block specified for one of the subnets in a Virtual Cloud Network (VCN) is not correct and want to delete the subnet. While deleting you get an error indicating that there are still resources that you must delete first. The error includes the OCID of the VNIC that is in the subnet.
Which of the following action you will take to troubleshoot this issue?

• A. Use OCI CLI to delete the VNIC first and then delete the subnet.
• B. Use OCI CLI to delete the subnet using -force option.
• C. Use OCI CLI to call "network vnic" and "compute vnic-attachment" operations to find out the parent resource of the VNIC.
• D. Copy and paste OCID of the VNIC in the search box of the OCI Console to find out the parent resource of the VNIC.

Which of the below options for private access to services within Oracle Cloud Infrastructure (OCI) is NOT valid?

• A. You can enable private access to certain services within OCI from your Virtual Cloud Network by using either a private endpoint or a service gateway.
• B. Traffic from an OCI compute instance going through a Service Gateway to Object Storage is routed without being sent over the internet.
• C. The private endpoint gives hosts within your Virtual Cloud Network access to a given service within Oracle Cloud Infrastructure.
• D. You cannot use the private endpoint for hosts in the on-premises network.

You are building a highly available and fault tolerant web application deployment for your company. Similar application delayed by competitors experienced web site attack including DDoS which resulted in web server failing.
You have decided to use Oracle Web Application Firewall (WAF) to implement an architecture which will provide protection against such attacks and ensure additional configuration will you need to implement to make sure WAF is protecting my web application 24*7.
Which additional configuration will you need to Implement to make sure WAF Is protecting my web application 24*7?

• A. Configure auto scaling policy and it to WAF instance.
• B. Configure new rules based on now vulnerabilities and mitigations
• C. Configure multiple origin servers
• D. Configure Control Rules to send traffic to multiple web servers

You have deployed a web application targeting a global audience across multiple Oracle Cloud Infrastructure (OCI) regions.
You decide to use Traffic Management Geo-Location based Steering Policy to serve web requests to users from the region closets to the user. Within each region you have deployed a public load balancer with 4 servers in a backend set. During a DR test disable all web servers in one of the regions however, traffic Management does not automatically direct all users to the other region.
Which two are possible causes?

• A. Rather than using Geo-Location based Steering Policy, you should use Failover Policy Type to serve traffic.
• B. You did not setup a Route Table associated with load Balancer's subnet
• C. One of the two working web servers In the other region did not pass Its HTTP health check
• D. You did not setup an HTTP Health Check associated with Load Balancer public IP in the disabled region.
• E. You did not correctly setup the Load Balancer HTTP health check policy associated with backend set

You have multiple IAM users who launch different types of compute Instances and block volumes every day. As a result, your Oracle cloud Infrastructure (OCF) tenancy quickly hit the service limit and you can no longer create any new instances. As you are cleaning up environment, you notice that the majority of the Instances and block volumes are untagged. Therefore, It is difficult to pinpoint the owner of these resources verify if they are safe to terminate.
Because of this, your company has issued a new mandate, which requires adding compute instances.
Which option is the simplest way to implement this new requirement?

• A. Create a policy to automatically tag a resource with the user name.
• B. Create tag variables for each compartment to automatically tag a resource with the user name.
• C. Create a default tag for each compartment, which ensure that appropriate tags are applied at resource creation
• D. Create tag variables to automatically tag a resource with the user name.
• E. Create a policy using IAM requiring users to tag specific resources. This will allow a user to launch compute instances on\y if certain tags were defined.
