Click the Exhibit button. Referring to the exhibit, which two statements are correct about the ping command? (Choose two.)

The Junos OS ping command syntax is ping [options] host. In the exhibited command, ping routing-instance DMZ 10.10.102.10, the routing-instance DMZ option specifies the routing instance from which the ICMP echo request originates. This means the source interface and routing table used for the ping are those associated with the DMZ routing instance. The host argument, 10.10.102.10, is the target device to which the ICMP echo requests are sent, making it the destination address.

B. The 10.10.102.10 IP address is the source. This is incorrect. The IP address specified as the final argument in a ping command is always the destination host.
D. The DMZ routing-instance is the destination. This is incorrect. A routing instance is a logical routing and forwarding context on the local device; it is not a network endpoint that can be a destination for a ping.

1. Juniper Networks TechLibrary - Junos OS CLI Reference

ping command: The documentation specifies the routing-instance routing-instance-name option to "Ping from a specified routing instance." This confirms the routing instance is the source context for the operation. The host parameter is defined as the remote host to ping

which is the destination.

2. Juniper Networks TechLibrary - Routing Instances Overview: This document explains that a routing instance is a collection of routing tables

interfaces

and routing protocol parameters. This clarifies that it is a logical construct on the router and not a destination address.
