Security, Professional (JNCIP-SEC)

Question No: 41

You are using destination NAT to translate the address of your HTTPS server to a private address on your SRX Series device. You have decided to implement IDP SSL decryption. Upon enabling the decryption, you notice sessions are not decrypted.

Which action resolves the problem?

  1. Replace the server SSL certificate to use the public address.

  2. Reboot the SRX Series device.

  3. Increase the SSL session-id-cache-timeout value to any value greater than 5000 seconds.

  4. Enable the IDP sensor-configuration detector to detect address translation.

Answer: D

Question No: 42

You are asked to secure your company’s Web presence. This includes using an SRX Series device to inspect SSL traffic going to the Web servers in your DMZ.

Which two actions are required to accomplish this task? (Choose two.)

  1. Load your Web server’s private key in the IDP configuration.

  2. Load your Web server’s public key in the IDP configuration.

  3. Generate a root certificate on the SRX Series device for your Web servers.

  4. Specify the number of sessions in the SSL sensor configuration.

Answer: A,D

Question No: 43

You have recently deployed a dynamic VPN. The remote users are complaining that communications with devices on the same subnet as the SRX device are intermittent and often fail. The tunnel is stable and up, and communications with remote devices on

different subnets work without any issues. Which configuration setting would resolve this issue?

  1. adding local-redirect at the [edit security nat] hierarchy

  2. adding local-redirect at the [edit interfaces lt;interface-namegt;] hierarchy

  3. adding proxy-arp at the [edit security nat] hierarchy

  4. adding proxy-arp at the [edit interfaces lt;interface-namegt;] hierarchy

You are using AppDoS to protect your network against a bot attack, but noticed an approved application has falsely triggered the configured IDP action of drop. You adjusted your AppDoS configuration as shown in the exhibit. However, the approved traffic is still dropped.

What are two reasons for this behavior? (Choose two.)

  1. The approved traffic results in 50,000 HTTP GET requests per minute.

  2. The approved traffic results in 25 HTTP GET requests within 10 seconds from a single host.

  3. The active IDP policy has not been defined in the security configuration.

  4. The IDP action is still in effect due to the timeout configuration.

Answer: A,D
