A new server has been set up in your environment. The administrator suspects that the firewall is blocking the traffic from the new server. Previously existing servers in the VLAN are working correctly. After reviewing the logs, you do not see any traffic for the new server.

Referring to the exhibit, what is the cause of the problem?

  1. The server is in the wrong VLAN.

  2. The server has been misconfigured with the wrong IP address.

  3. The firewall has been misconfigured with the incorrect routing-instance.

  4. The firewall has a filter enabled to block traffic from the server.

Question No: 74

You are attempting to establish an IPsec VPN between two SRX devices. However, there is another device between the SRX devices that does not pass traffic that is using UDP port 4500.

How would you resolve this problem?

  1. Enable NAT-T.

  2. Disable NAT-T.

  3. Disable PAT.

  4. Enable PAT.

Answer: B Explanation:

NATT also uses UDP port 4500 (by default) rather than the standard UDP. So disabling NAT-T will resolve this issue.
