Juniper Exam JN0-231 Topic 8 Question 51 Discussion

Actual exam question for Juniper's JN0-231 exam

Question #: 51
Topic #: 8

Your ISP gives you an IP address of 203.0.113.0/27 and informs you that your default gateway is 203.0.113.1. You configure destination NAT to your internal server, but the requests sent to the webserver at 203.0.113.5 are not arriving at the server.

In this scenario, which two configuration features need to be added? (Choose two.)

Afirewall filter

Bsecurity policy

Cproxy-ARP

DUTM policy

Show Suggested Answer

Suggested Answer: A, C

Junos-host and null are two non-configurable zones that exist by default on an SRX Series device. Junos-host is the default zone for all internal interfaces and services, such as management and other loopback interfaces. The null zone is used to accept all traffic that is not explicitly accepted by other security policies, and is the default zone for all unclassified traffic. Both zones cannot be modified or deleted.

Ah, the classic 'my webserver is invisible' problem. Guess the network team forgot to enable the 'make server visible' option. I hear they're offering a special 'Networking for Dummies' course, maybe they should sign up!

No, I believe we need to add security policy and UTM policy.

I think we need to add firewall filter and proxy-ARP.

Firewall filter will allow the traffic to reach the server.

Proxy-ARP will help with the ARP resolution for the server.

Proxy-ARP and firewall filter, no doubt. Seems like the network team needs to brush up on their networking 101. Maybe they should consider a career in comedy instead - they're killing it with this configuration.

The network team should definitely review their networking knowledge if they missed these basic configurations.

I agree, those two configurations should solve the issue with the requests not reaching the server.

Proxy-ARP and firewall filter are definitely needed here. The network team needs to fix this.

Proxy-ARP and firewall filter, for sure. I bet the network admin was snoozing on the job when they set this up. Time to wake them up and get this server working!

Okay, I see what's going on here. Proxy-ARP is definitely the way to go, and a firewall filter to control the traffic flow. Security policy and UTM policy don't sound like the right solutions for this problem.

Hmm, this seems like a classic networking issue. I'm guessing we need to enable proxy-ARP to handle the NAT configuration properly. And maybe a firewall filter to ensure the traffic is being routed correctly.
