A customer has several remote sites connected with their headquarters through microwave links.
An engineer must propose a backup WAN solution based on these conditions:
- A physical WAN solution is not available for most of the sites.
- The customer has a limited budget and a short time frame for
implementation.
- The backup link will have low bandwidth requirements.
- Users will tolerate a WAN outage of up to 2 hours.
Which backup WAN link type should the engineer recommend?

Refer to the exhibit. A customer needs to apply QoS to the network management traffic passing through the GigabitEthernet0/2 interface. All eight queuing classes are in use, so the new requirement must be integrated into the existing policy. Which solution must the customer choose?

Prior to establishing full-mesh IPsec tunnels in a typical Cisco SD-WAN deployment, which mechanism do WAN Edge routers use to exchange key information for data plane encryption?

Refer to the exhibit. An engineer must ensure that the QoS design guarantees bandwidth for the applications, and an application can request a particular type of service to support its delay requirements. Which solution must the engineer select?

A company is planning to open two new branches and allocate the 2a01:c30:16:7009::3800/118 IPv6 network for the region. Each branch should have the capacity to accommodate maximum of
200 hosts. Which two networks should the company use? (Choose two.)
