As a solution architect, you are showcasing the Oracle Cloud Infrastructure (OCI) Object Storage feature about Object Versioning to a customer. Which statement is true in regards to OCI Object Storage Versioning?. Object versioning does not provide data protection against accidental or malicious object update, overwrite, or deletion. By default, object versioning is disabled on a bucket. A bucket that is versioning-enabled can have only and always will have a latest version of the object in the bucket. Objects are physically deleted from a bucket when versioning is enabled.

You created a public subnet and an internet gateway in your virtual cloud network (VCN) of Oracle Cloud Infrastructure. The public subnet has an associated route table and security list. However, after creating several compute instances in the public subnet, none can reach the Internet. Which two are possible reasons for the connectivity issue? (Choose two.). The route table has no default route for routing traffic to the internet gateway. There is no stateful egress rule in the security list associated with the public subnet. There is no dynamic routing gateway (DRG) associated with the VCN. There is no stateful ingress rule in the security list associated with the public subnet. A NAT gateway is needed to enable the communication flow to internet.

You are designing a lab exercise with an application that includes a large number of graphics with large file sizes.
