You are configuring MPLS traffic-engineering tunnels in the core. Which two ways exist for the tunnel path across the core? (Choose two )

By default, MPLS TE tunnels utilize the Interior Gateway Protocol (IGP) metrics to calculate their paths, unless specific administrative weights or TE metrics are explicitly configured to override this behavior.

MPLS Traffic Engineering offers two primary methods for path selection: a dynamic path, where the router computes the path based on constraints, and an explicitly defined path, where an administrator manually specifies the exact sequence of hops.

A zero bandwidth tunnel is a valid option in MPLS TE, used when specific bandwidth reservation is not required but other constraints are still desired.

The `bandwidth` statement in MPLS TE creates a 'soft' reservation, informing the CSPF algorithm of requirements, but it doesn't necessarily enforce a 'hard' reservation at the link level without additional QoS mechanisms.

The dynamic path option for MPLS TE is supported with both OSPF and IS-IS as the underlying IGP, not exclusively with IS-IS.
