Q: 6
Which feature will an operator use while implementing MPLS TE on customer's network, to prevent
an LSP from using any overseas inks?

C. not B
C tbh
C every time for this. Explicit path means you pick the exact hops so there's zero risk of hitting an overseas link, while affinity just influences the selection. Pretty sure C is right here, unless I’m missing something.
If the topology changes and a new overseas link pops up with the same color/affinity, B would fail to keep the LSP off it. Only C, explicit path, guarantees exclusion even if something shifts. Anyone hit an edge case where affinity set worked instead?
C
Explicit path is the only way to be sure overseas links are completely avoided. Affinity can influence but not guarantee it, so C is really the most solid pick here. Pretty certain but open if someone knows an odd scenario.
Its B
I get why some might pick B since affinity can exclude links, but only C (explicit path) actually guarantees the LSP won't touch overseas circuits. Affinity can be bypassed if no alternatives exist-C is stricter. Agree?
C imo. With explicit path, you hard-code which links the LSP can use, so you just leave out any overseas hops. Affinity is more for broad policy tagging but won't guarantee avoidance as strictly. Similar scenario popped up in labs and the official guide.
Maybe B here. Affinity can be set with link coloring to exclude certain links like overseas ones. Nice question, very clear wording! Not totally sure, but affinity bits are often used for link-level policies.
Be respectful. No spam.
