Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A routing policy containing the 'load-balance' action statement.
Why this is correct
A policy defining the load-balance action is required.
- ✓
Application of the export policy under 'set routing-options forwarding-table export'.
Why this is correct
The policy must be exported to the forwarding table to instruct the PFE to install multiple next-hops.
- ✗
Setting the routing-instance type to 'forwarding'.
Why it's wrong here
Standard routing-options export applies to the default routing instance as well.
- ✗
Enabling MPLS encapsulation on all core interfaces.
Why it's wrong here
Load balancing works for native IP traffic as well as MPLS traffic; MPLS is not a requirement.
- ✗
A firewall filter applied to every interface running BGP.
Why it's wrong here
Firewall filters are not required for standard IP routing table load balancing.
