You are deploying new WAN services between two routers and you are required to encrypt all traffic at Layer 2 Which solution would satisfy this requirement?

Your customer wants to enable their MX Series core so that a controller can dynamically manage their LSPs.
Which protocol provides this capability?

Your client asked you to design a solution with the requirements shown below.
- Have better traffic engineering for applications across an existing MPLS core.
- Support both IPv4 and IPv6 traffic
- Work with an MX Series core.
- Work with a North Star Controller
- Work with existing IGP (ISIS)
Which feature would you recommend be implemented in this solution?

You are asked to design a WAN for a large enterprise. Each site must have multiple connections for redundancy. MPLS is not available at every site but it is preferred where available.
Which topology satisfies these design requirements?

You are creating a WAN solution design for an enterprise customer. The customer will be connecting three sites in different locations. The customer wants all of the sites to be part of the same Layer 2 network.
In this scenario, what are two valid connection methods that you would provide in your design? (Choose two.)
