End-To-End Packet Flow and Forwarding JN0-364 Practice Questions (Page 3)
Part of the Multiprotocol Label Switching (MPLS) domain, which makes up ~16% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~6–10 in this domain), expect 1–1 from this objective — we provide 28 practice questions to prepare you well beyond it.

An IP packet with a TTL of 10 enters an MPLS network at the ingress LSR. The LSP has three hops (ingress, transit, egress). The network uses the default TTL propagation behavior. What will be the TTL of the IP packet when it exits the MPLS network at the egress LSR?
