A. B. C. D.A
The correct command to configure a default route toward the upstream ISP at IP address 192.168.100.1 on a Juniper MX240 is A. set routing-options static route 0.0.0.0/0 next-hop 192.168.100.1.
Here's a detailed explanation of why this command is correct and why the other options are incorrect:
A. set routing-options static route 0.0.0.0/0 next-hop 192.168.100.1: This command sets a static route for all traffic (0.0.0.0/0) to use the next-hop address 192.168.100.1, which is the IP address of the upstream ISP. This is the correct command to configure a default route.
B. set routing-options default route 0.0.0.0/0 next-hop 192.168.100.1: This command is incorrect because the syntax is incorrect. There is no "default route" option in the routing-options hierarchy.
C. set forwarding-options static route 0.0.0.0/0 next-hop 192.168.100.1: This command is incorrect because it is setting a static route in the forwarding-options hierarchy, which is used for configuring various forwarding features such as filters, policers, and classifiers. It is not used for configuring routing.
D. set protocols default route 0.0.0.0/0 next-hop 192.168.100.1: This command is incorrect because it is setting a default route in the protocols hierarchy, which is used for configuring routing protocols such as BGP, OSPF, and IS-IS. It is not used for configuring static routes.
Therefore, the correct command to configure a default route toward the upstream ISP at IP address 192.168.100.1 on a Juniper MX240 is A. set routing-options static route 0.0.0.0/0 next-hop 192.168.100.1.
