You are system administrator at a retail company. You Just received a ticket stating that the account team is unable to access an internal application. The application is running behind an Oracle Cloud Infrastructure (OCI) Public Load Balancer and is using a compute instance pool with autoscaling enabled. You noticed some deleted items In the Audit Log while troubleshooting. Which resource deletion could have caused this Issue?
Correct Answer: D
To delete a route table Prerequisite: To delete a route table, it must not be associated with a subnet yet. You can't delete the default route table in a VCN. To delete an internet gateway Prerequisite: The internet gateway does not have to be disabled, but there must not be a route table that lists it as a target. Each VCN automatically comes with a default route table that has no rules. If you don't specify otherwise, every subnet uses the VCN's default route table. When you add route rules to your VCN, you can simply add them to the default table if that suits your needs. However, if you need both a public subnet and a private subnet (for example, see Scenario C: Public and Private Subnets with a VPN), you instead create a separate (custom) route table for each subnet. Each subnet in a VCN uses a single route table. When you create the subnet, you specify which one to use. You can change which route table the subnet uses at any time. You can also edit a route table's rules, or remove all the rules from the table.
