While troubleshooting a device, you see that it is permitting packets for which it appears there is no policy.
Using the information in the exhibit, what is causing this behavior?
A. It is permitted due to a default permit policy.
B. It is permitted due to a stale policy.
C. It is permitted due to a global policy.
D. It is permitted due to an ALG.
正解:D
質問 2:
You recently configured the antivirus feature profile on your Junos device. The security policy is sending traffic for antivirus scanning. However, the traffic is being blocked and you repeatedly receive the system log message that the scan engine is not ready. You must not allow the traffic to be dropped when the scan engine is not ready.
Which action will resolve this problem?
A. Configure antivirus trickling to prevent the scan engine from timing out.
B. Configure an antivirus file scanning extension list to reduce the number of files for scanning.
C. Configure an antivirus content size limit to minimize the scanning of large files.
D. Configure an antivirus fallback option to permit the traffic when the scan engine is not ready.
正解:D

Your customer is attempting to reach a new server that should be accessible publicly using
192.168.100.100 on TCP port 5000, and internally using 10.100.100.1 on TCP port 5555. You notice no sessions form when the customer attempts to access the server.
Referring to the exhibit, what will resolve this problem?
A. The NAT pool server must use port 5000.
B. There must be a TRUST-to-UNTRUST security policy to allow return traffic.
C. The UNTRUST-to-TRUST security policy must allow port 5555.
D. The NAT rule set rule1 must match on port 5555.
正解:C
質問 4:
You are asked to troubleshoot a user communication problem. Users connected to the Trust zone cannot communicate with other devices connected to the same zone. These users are able to communicate with other devices in all other zones.
How should you resolve this problem?
A. You must enable the all parameter for host inbound traffic for the zone.
B. You must enable the allow-internal parameter under the Trust security zone.
C. You must configure a security policy to allow intrazone communication.
D. You must put each device in a separate subzone to allow internal communication.
正解:C
