The correct answers are A. Service gateway and E. Default subnet.

Explanation: A Virtual Cloud Network (VCN) is a customizable and private network in the Oracle Cloud Infrastructure. A VCN is comprised of components like subnets, route tables, security lists, internet gateways, NAT gateways, service gateways, and more.

Here are the explanations for the two components that cannot be deleted in a VCN:

A. Service gateway: A service gateway is a virtual router that provides access to other Oracle Cloud Infrastructure services like Oracle Cloud Infrastructure Object Storage, Oracle Cloud Infrastructure Block Volumes, Oracle Cloud Infrastructure File Storage, etc., from instances within a VCN without exposing them to the public internet. You cannot delete the service gateway of a VCN.

E. Default subnet: A subnet is a range of IP addresses in your VCN. The default subnet is automatically created when you create a VCN. It contains a default route table and a default security list. The default subnet is used for resources that don't have a specific subnet specified. You cannot delete the default subnet of a VCN. However, you can disable it or create a new subnet and set it as the default.

B. Default security list, C. Routing gateway, and D. Default route table can be deleted:

  • Default security list: The default security list is automatically created when you create a VCN. It contains default ingress and egress rules that allow traffic within the VCN. You can modify or delete the default security list.
  • Routing gateway: A routing gateway is used to connect a VCN with other networks using dynamic routing protocols like Border Gateway Protocol (BGP). You can delete a routing gateway if it's not attached to any attachment.
  • Default route table: The default route table is automatically created when you create a VCN. It contains a default route rule that sends traffic to the internet gateway. You can modify or delete the default route table.
