Exam CV0-003 topic 1 question 7 discussion

Peering Network connectivity that permits instances to communicate between two virtual private clouds using reserved IP addresses. Peering connects two or more virtual networks. The virtual networks appear to consumers as a single network. In addition, fast connectivity is provided between the two networks, making data and resource access very efficient. Peering is used in the hub-and-spoke model to connect the spoke networks with the hub network. Note that the spoke networks are not peered to each other in the hub-and-spoke model.

I think the clue in the question is this "There is currently one virtual network..." and I'm not sure how IPAM helps if you're out of IP addresses.

Explanation: When a virtual network in a public cloud environment runs out of available IP addresses, the best approach is to create a new Virtual Private Cloud (VPC) and peer it with the existing network. This allows additional servers to be provisioned without disrupting the current infrastructure.

Option D is the right answer to this question. Obtain a new IPAM (IP Address Management) subscription. This will allow the engineer to acquire additional IP addresses to accommodate the growing number of servers in the cloud environment. In the AWS Cloud Ecosystem IPAM is used by cloud engineers and administrators to request more IP addresses whenever there is IP address shortage and needs IP address scaling.

A. Create a VPC and peer the networks. Explanation: Creating a Virtual Private Cloud (VPC) allows for the segmentation and isolation of network resources within the cloud environment. Peering the networks enables communication between multiple VPCs while keeping them logically separate. By creating additional VPCs and peering them with the existing network, the engineer can effectively expand the available IP address space and accommodate the growing number of servers in the environment. Option D (voted by 20%), obtaining a new IPAM (IP Address Management) subscription, may help manage IP addresses but does not inherently expand the IP address space.

A VPC lets you use "private space" aka non-routable IPs, meaning you can pretty much extensively use all the possible IPs bc you dont have to worry about not using the same IP as some random public device. With peering, you can set up a public machine that can access private space, so a connection can use that machine to jump from public to private, making private routable.

Create a VPC and Peer the Networks. This option directly addresses the issue by expanding the available IP address space through the creation of a new network (VPC) and then linking it with the existing network for seamless operation. This approach not only resolves the immediate problem but also provides a scalable structure for future expansion.

Neither "B", "C" or "D" will provide addresses to the VPC in question that it doesn't already have. Creating a new VPC and peering the two will allow growth on the new VPC and both VPC's can communicate as if they're on the same network.

Its definatly NOT C. DHCP cannot give out addresses you just dont have. Its either A or D. I will do a bit more research and come back with my take.

DHCP is a protocol that automatically assigns IP addresses to devices on a network. By enabling DHCP on the network, the cloud engineer can automatically assign IP addresses to new servers as they are provisioned in the environment. This will allow the environment to accommodate additional servers without having to manually configure IP addresses.

I think it's C. Enabling DHCP on the networks would be the most appropriate solution to accommodate additional servers in the public cloud environment. DHCP (Dynamic Host Configuration Protocol) is a network protocol that allows the automatic assignment of IP addresses and other network configuration settings to devices on a network. By enabling DHCP on the virtual network, the cloud engineer can automatically assign IP addresses to new servers as they are added to the network, without needing to manually assign IP addresses.

To accommodate additional servers in the environment when the current virtual network has no more available IP addresses, the cloud engineer should enable DHCP on the network. Dynamic Host Configuration Protocol (DHCP) is a network protocol that automatically assigns IP addresses to devices on a network. By enabling DHCP on the network, the engineer can ensure that any new servers that are added to the environment will be automatically assigned an available IP address. Creating a new Virtual Private Cloud (VPC) and peering the networks or implementing dynamic routing are other options that could help with network scalability. However, in this scenario, enabling DHCP on the existing network is likely the most straightforward and efficient solution. Obtaining a new IP Address Management (IPAM) subscription is not necessary, as enabling DHCP on the existing network can handle the situation.

Obtaining a new IPAM subscription may provide additional IP addresses, but it is not the most efficient or cost-effective solution. Creating a new network with a VPC and peering the networks is a better approach as it allows for more flexibility in managing and scaling the environment.

A is the correct answer, at first I thought IPAM as well, but it would not address the issue of running out of IP addresses, just managing them. So VPC would allow more.

I think D for reasons already stated by TheGinjaNinja

D. Obtain a new IPAM (IP Address Management) subscription. This will allow the engineer to acquire additional IP addresses to accommodate the growing number of servers in the cloud environment.
