Selected Answer: AE The provided answers are for the benefits of SD-WAN compared to traditional WAN

I'd choose A & E

Selected Answer: AE I agree with that

Selected Answer: AE A and E seem valid

A traditional WAN may have lower control plane abstraction and lower data plane overhead than an SD-WAN solution. Traditional WANs usually have a simpler architecture where the control plane (which is responsible for routing decisions) and the data plane (which carries the user data) are not separated. This gives lower control plane abstraction. Also, since traditional WANs are not overlay networks like SD-WANs, they generally have less data plane overhead. Overlay networks add extra information (headers) to the original packets, which increases overhead and can make bandwidth use less efficient. It's important to note that while these may be seen as benefits in certain cases, the trade-offs include less flexibility, more complex configuration and management, and lack of some features like centralized control, easy scalability, and advanced traffic management that are typically found in SD-WAN solutions.

Selected Answer: AE By a mile, AE!

Selected Answer: BC Traditional WAN solutions often have simpler network architectures and fewer components than SD-WAN. This can lead to faster fault detection, since there are fewer possible points of failure and network issues can be identified more easily. Simplified troubleshooting: With a traditional WAN, the network topology and configuration are usually more straightforward and standardized. This can make troubleshooting easier, as network administrators can have a clearer grasp of the network design and can more easily spot and fix issues. SD-WAN offers benefits like lower control plane abstraction, comprehensive configuration standardization, and lower data plane overhead.

Selected Answer: AE AE, IMHO

Selected Answer: CE C. simplified troubleshooting: Traditional WANs, typically based on protocols like MPLS, OSPF, or BGP, use well-established technologies with standardized, widely understood troubleshooting tools (e.g., ping, traceroute, SNMP). These are familiar to most network engineers, making issue diagnosis and resolution more straightforward. In contrast, SD-WAN introduces complexities like overlay networks, tunneling (e.g., VXLAN or IPsec), and centralized controllers, which may require specialized tools and knowledge, potentially complicating troubleshooting. E. lower data plane overhead: Traditional WANs, especially those using MPLS or direct routing, have lower data plane overhead because they avoid the additional encapsulation and tunneling protocols (e.g., IPsec or VXLAN) used in SD-WAN to create overlay networks. These encapsulations add header overhead and processing demands, whereas traditional WANs typically rely on simpler forwarding mechanisms, reducing resource usage on the data plane.

Selected Answer: AE A, E are correct
