Which feature is supported on the Cisco vEdge platform?

A network engineer prepares a script to configure a loopback interface with IP address
172.16.15.12/32. To comply with the company security policies, 'Content-type': 'application/yang- data+json' is added to the script. Connection to the network devices must be secured. Which code snippet must the network engineer use to meet this requirement?

Refer to the exhibit. An engineer must design a WAN solution so that ISP-1 is always preferred over ISP-2. The path via ISP-2 is considered as a backup and must be used only when the path to ISP-1 is down. Which solution must the engineer choose?

An architect is designing a network for an enterprise site. The design must use an active/backup design for the WAN. It must guarantee the SLA for several applications regardless of which connection is used. Which deployment model should the architect choose?

An architect must design a topology for a WAN network that satisfies these requirements:
- Devices must be able to make informed decisions.
- Suboptimal paths are allowed only in case of a failure.
- Backup paths must always be available.
Which topology must the architect select?
