Q: 15
Which statement is correct about IS-IS?

I’d say C. IS-IS is actually link-state, not distance vector. B looks like a trap since path vector is usually for BGP. Correct me if I'm missing something.
C not A. IS-IS is definitely link-state, uses SPF, not distance vector like RIP or EIGRP. Pretty sure about this.
For me, A. I remember from a similar question that IS-IS acts like a distance vector protocol because it propagates routing info across routers, kind of like RIP. The trap here could be between distance vector and link-state since both share some convergence methods. Open to being corrected if I missed something technical.
Its C
