Customer XYZ network consists of an MPLS core. IS-IS running as IGP a pair of BGP route reflectors for route propagation, and a few dozens of MPLS-TE tunnels for specific tactical traffic engineering requirements. The customer's engineering department has some questions about the use of the Overload Bit in the IS-IS networks and how it could be used to improve their current network design. Which two concepts about the Overload Bit are true? (Choose two.)

• A.It can be set on a router until other interacting protocols have signaled convergence.
• B.It is not recommended on BGP Route Reflectors
• C.Networks advertised within the LSPs of the respective node will become unreachable
• D.It forces the midpoint MPLS-TE node to reoptimize the primary tunnels going through the OL node.
• E.It can be set on a router during the startup process for a fixed period of time

What best describes the difference between Automation and Orchestration?

• A.Automation describes a hands-off configuration process while Orchestration refers to sets of automation tasks that require the network administrator to coordinate
• B.Automation refers to an automatic process for completing a single task and Orchestration refers to assembling and coordinating a set of tasks and conditions.
• C.Automation refers to scripting languages (Python. Ansible etc.) and Orchestration refers to commercial products that control configuration deployment
• D.Automation refers to an automatic process for completing multiple tasks with conditions and Orchestration refers to executing tasks in parallel.
