What is the purpose of the 'routing-options' configuration in the context of Martian address filtering?

To configure SNMP community strings

To configure static routes that discard traffic to Martian destinations

An administrator applied a firewall filter to reject packets with Martian source addresses on an interface. After some time, they want to confirm that the filter is actually dropping packets. Which command provides the most direct evidence of packets being discarded by the filter?

How does filtering Martian addresses help prevent IP spoofing?

By requiring authentication for all packets before they are routed

By discarding packets with source addresses that are not valid on the public internet

By limiting the number of packets a source can send per second

By encrypting all packets to prevent tampering with the source address

A network engineer is explaining to a junior colleague why the edge router should drop packets with source addresses from the 192.168.0.0/16 range. Which reason is the most accurate?

These packets may be spoofed because the source range is not globally routable, and filtering prevents them from entering the network.

These packets will cause routing loops because the router cannot find a route for them.

These packets consume extra bandwidth because the router must perform NAT for them.

These packets are always malformed and will be dropped by the hardware anyway.

Why are Martian addresses considered 'not valid on the public internet'?

Because they are not globally unique and are reserved for private or special use

Because they are generated by malicious software

Because they are assigned to devices that are not connected to the internet

Because they are too old to be supported by modern routers

Martian Addresses JN0-281 Practice Questions (Page 2)

Part of the Protocol-Independent Routing 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 1–2 from this objective — we provide 11 practice questions to prepare you well beyond it.
