A cloud engineer is responsible for managing a public cloud environment.
There is currently one virtual network that is used to host the servers in the cloud environment.
The environment is rapidly growing, and the network does not have any more available IP addresses.
Which of the following should the engineer do to accommodate additional servers in this environment?

When faced with a shortage of available IP addresses in a cloud environment, the cloud engineer must find a solution to accommodate additional servers. There are several possible solutions, but some are better suited than others depending on the specific requirements of the environment.
A. Create a VPC and peer the networks:
A VPC (Virtual Private Cloud) is a logically isolated section of a public cloud environment that allows you to launch resources in a virtual network that you define. By creating a new VPC and peering it with the existing network, you can expand the IP address range available to the environment. This option is a good choice when you want to add a significant number of new servers to the environment and need to ensure that they are completely isolated from other parts of the environment.
B. Implement dynamic routing:
Dynamic routing is a method of automatically calculating the best path for network traffic to take based on the current network conditions. By implementing dynamic routing protocols such as OSPF or BGP, the cloud environment can adapt to changes in the network topology and routing paths, potentially freeing up some IP addresses. However, this solution is not suitable when the network is completely out of available IP addresses and needs to add more servers to accommodate growth.
C. Enable DHCP on the networks:
DHCP (Dynamic Host Configuration Protocol) is a protocol that assigns IP addresses to devices automatically. By enabling DHCP on the network, you can ensure that every new server that is added to the environment is assigned an IP address automatically, potentially freeing up some manually assigned IP addresses. However, this solution does not solve the underlying problem of a limited IP address range and can lead to IP conflicts if not properly configured.
D. Obtain a new IPAM subscription:
IPAM (IP Address Management) is a software tool that enables the centralized management of IP addresses. Obtaining a new IPAM subscription can provide additional IP addresses that can be used to accommodate additional servers. However, this solution may be costly and does not solve the underlying problem of a limited IP address range.
In conclusion, the best option for a cloud engineer to accommodate additional servers in a rapidly growing environment with a shortage of IP addresses would be to create a VPC and peer the networks. This solution allows for complete isolation of the new servers and expands the IP address range available to the environment.
