Refer to the exhibit. In this BGP design, what is the next hop for 10.1.1.0/24 on R8 and R7?

When R8 advertises 10.1.1.0/24 to R7 (via eBGP or iBGP with next-hop-self), R7 installs R8's address as the next hop, and symmetrically R8 installs R7's address as the next hop for routes received from R7; this mutual next-hop relationship is a direct result of standard BGP next-hop attribution to the advertising peer.

Assigning R5 as next-hop on R7 and R6 as next-hop on R8 would require R7 and R8 to have learned the prefix from R5 and R6 respectively via separate sessions, which contradicts the mutual peering relationship indicated by answer A being correct.

This reverses the R5/R6 assignment (R6 for R7, R5 for R8), which is inconsistent with the BGP topology described and does not reflect how next-hop attribution works between directly peering BGP speakers.

R3 and R4 as next-hops would only apply if R7 and R8 received the prefix from R3 and R4 directly, and the design does not reflect this direct session relationship for this prefix.
