A global organization with several branches hired a network architect to design an overlay VPN solution. The branches communicate with each other frequently. The customer expects to add more branches in the future.
To meet the customer's security requirements, the architect plans to provide traffic protection using dynamic IPsec tunnels. Which solution should the architect choose?

Refer to the exhibit. The connection between SW2 and SW3 is fiber and occasionally experiences unidirectional link failure. An architect must optimize the network to reduce the change of layer2 forwarding loops when the link fails. Which solution should the architect include?

Refer to the exhibit. Which two solutions maximize the use of the links between the core and distribution layers? (Choose two.)

Refer to the exhibit. A network engineer must design a BGP solution based on:
* The route reflector must have one or more direct physical connections to the core routers (R3 and R4).
* The route reflector must have full redundancy and avoid a single point of failure.
* R2 to R1 link utilization is 90%. and the remaining links are less than 50% utilized.
Which two solutions must the design Include?(Choose two.)

A network administrator is troubleshooting a DMVPN setup between the hub and the spoke.
Which action should the administrator take before troubleshooting the IPsec configuration?
