The configuration snippet shown is for HSRP (Hot Standby Router Protocol) on a Cisco router interface. It indicates that preemption is enabled with a delay sync of 100 seconds. This means if R1 fails and then regains operational status, it will wait for 100 seconds before attempting to become the active router again, allowing time for routing protocols to converge. References := Cisco Implementing and Operating Cisco Service Provider Network Core Technologies Course

Traffic shaping is a bandwidth management technique that delays the flow of out-of-profile traffic to ensure compliance with a specified traffic profile. It buffers excess packets until there is available bandwidth, rather than dropping them immediately. This helps in controlling the amount of traffic sent into the network, preventing congestion1.

In a PIM-SM (Protocol Independent Multicast sparse mode) network, the Rendezvous Point (RP) serves as the central hub for connecting multicast sources with receivers. It acts as the meeting place where sources send their traffic, which is then forwarded down a shared distribution tree to the receivers1.

 To complete the NAT configuration on R1, the commands should specify which interfaces are inside and outside relative to NAT. The correct set of commands would be:

R1(config)# interface GigabitEthernet 0/0

R1(config-if)# ip nat inside

R1(config)# interface GigabitEthernet 0/1

R1(config-if)# ip nat outside

This configuration designates the interfaces on R1 that will participate in NAT: GigabitEthernet 0/0 as the inside interface where the local network resides, and GigabitEthernet 0/1 as the outside interface facing the external network.
