What is a purpose for creating multiple routing instances on an SRX Series Firewall device?

1. A. to enable network monitoring through SNMP
2. B. to maintain separation of routing information for security purposes
3. C. to manage routing protocols and updates
4. D. to simplify the configuration of network interfaces

Correct Answer: B
Multiplerouting instances(such as virtual routers or VRFs) can be configured on an SRX to provide separation of routing tables. This enables:
Maintaining separation of routing information (Option B):Different departments, tenants, or customers can have their own independent routing domains for security and isolation.
SNMP monitoring (Option A) is unrelated to routing instances.
Routing protocols (Option C) can be run inside each instance, but the purpose of multiple instances is separation, not general routing protocol management.
Simplifying interface configuration (Option D) is not a function of routing instances.
Correct Purpose:To maintain separation of routing information for security purposes.

You are asked to reduce security configuration complexity on your external facing firewalls. You notice that a previous administrator included hundreds of private subnet NAT rules covering various RFC1918 addresses. You want to replace all these rules with a single rule covering all RFC1918 addresses.
Which rule would you use in this scenario?

1. A. set security nat source rule-set private-to-pub rule RFC1918 match source-address [10.0.0.0/8 192.168.0.0/16 172.16.0.0/12]
2. B. set security nat source rule-set private-to-pub rule RFC1918 match source-address [10.0.0.0/8 192.16.0.0/12 172.168.0.0/16]
3. C. set security nat source rule-set private-to-pub rule RFC1918 match source-address [10.0.0.0/8 172.168.0.0/16 192.0.2.0/24 203.1.113.0/24]
4. D. set security nat source rule-set private-to-pub rule RFC1918 match source-address [10.0.0.0/8 192.168.0.0/16 172.16.0.0/12 192.0.2.0/24]
