Which of the following statements about next-hop groups is TRUE?

Comprehensive and Detailed Explanation with Exact Extracts:

Option A is FALSE: Next-hop groups support indirect next-hops (non-local IPs requiring recursive lookup).

Extract from Nokia SR Linux Configuration Guide (Section: Next-Hop Groups):

"The next-hop can be a directly attached IP address or an indirect next-hop (e.g., a router IP not on a directly connected subnet)."

Option B is TRUE: Next-hop groups are reusable objects referenced by multiple static routes.

Extract from Nokia SR Linux Configuration Guide (Section: Next-Hop Groups):

"A single next-hop group can be referenced by multiple static routes, simplifying configuration for shared forwarding behavior."

Option C is FALSE: Blackhole next-hop groups silently drop traffic by default. ICMP unreachable messages require explicit configuration.

Extract from Nokia SR Linux Configuration Guide (Section: Blackhole Routes):

"When blackhole is configured, traffic is discarded without sending ICMP unreachable messages unless send-blackhole-icmp true is explicitly set."

Option D is FALSE: Next-hop groups support ECMP with multiple next-hops.

Extract from Nokia SR Linux Fundamentals Guide (Section: Next-Hop Groups):

"A next-hop group can define multiple next-hops for Equal-Cost Multi-Path (ECMP) load balancing."
