Exam CV0-003 topic 1 question 202 discussion

Explanation: An MPLS (Multiprotocol Label Switching) connection provides a secure, high-performance, and low-latency private connection between an on-premises data center and a cloud service provider (CSP). Unlike VPN solutions that rely on the public internet, MPLS offers dedicated bandwidth, reduced latency, and improved reliability, making it ideal for organizations with high-performance and low-latency requirements.

MPLS and IPSEC bought provide private network commmuncation. MPLS, however, focuses more on speed and low latency while IPSEC focuses on encryption while traversing public network. I would have gone with IPSEC as it is the most secure but MPLS focuses more on speed and performance which the second to last statement asks for.

B is the right answer for me. The catch here is to "Establish a connection between the on-premises data center and the new CSP infrastructure" An IPSec tunnel connection is a secure connection over the internet or a private network that encrypts data between two endpoints. This is often used to connect on-premises networks to cloud VPCs. On the other hand, VPC peering allows two Virtual Private Clouds (VPCs) to communicate with each other as if they are part of the same network. It enables private connectivity between VPCs within the same or different AWS accounts and regions, which is not the requirement of the question. However, It is very important to know that IPSec connections typically has higher latency due to encryption and internet routing, while VPC peering offers low-latency connectivity since it uses internal AWS infrastructure.

C. An MPLS connection: MPLS (Multiprotocol Label Switching) connections are designed to provide reliable, high-performance, and low-latency connections over a wide area. MPLS can be configured to provide secure connections and is ideal for linking data centers and cloud providers with predictable performance. An IPSec tunnel: While IPSec tunnels provide secure connections, they may not always provide the low latency required for performance-critical operations, especially if there is significant distance or variable network conditions between the sites.

IP Security (IPsec) is a protocol suite that provides integrity, confidentiality, and authentication of Internet Protocol (IP) packets. IPsec is most commonly used to create virtual private networks (VPNs) over insecure networks like the Internet.
