Your network engineer proposes to disable Martian address filtering on your core routers to reduce CPU load. You oppose this change. Which consequence best justifies keeping Martian filtering enabled?

It prevents the routing table from containing routes to private addresses, which could cause traffic to be black-holed.

It reduces the size of the routing table, improving convergence time.

It ensures that multicast traffic is not forwarded to unicast destinations.

It stops malicious packets with spoofed source addresses from entering the network and being forwarded.

Your edge router receives BGP routes from a transit provider. You notice that some routes have next-hop addresses that fall within the 169.254.0.0/16 range. You want to prevent these routes from being installed in the routing table while still accepting all other valid routes from the provider. Which configuration accomplishes this?

Add a static route for 169.254.0.0/16 with a next-hop of discard.

Enable martian address filtering globally on the routing instance.

Apply a firewall filter to the BGP session that rejects packets with a destination address in 169.254.0.0/16.

Configure a route filter that rejects routes with a next-hop address in 169.254.0.0/16 and apply it as an import policy on the BGP neighbor.

Which Junos configuration element is used to reject routes with Martian addresses?

A NAT rule applied to a security policy.

A firewall filter applied to an interface.

A class-of-service scheduler applied to a forwarding class.

A route filter applied to a routing policy.
