Question No: 31

What is a benefit of using a group VPN?

  1. It provides a layer of redundancy on top of a point-to-point VPN mesh architecture.

  2. It eliminates the need for point-to-point VPN tunnels.

  3. It provides a way to grant VPN access on a per-user-group basis.

  4. It simplifies IPsec access for remote clients.

Answer: B Explanation:

Question No: 33

You have been asked to establish a dynamic IPsec VPN between your SRX device and a remote user. Regarding this scenario, which three statements are correct? (Choose three.)

  1. You must use preshared keys.

  2. IKE aggressive mode must be used.

  3. Only predefined proposal sets can be used.

  4. Only policy-based VPNs are supported.

  5. You can use all methods of encryption.

Question No: 34

Click the Exhibit button.

– Exhibit –

You receive complaints from users that their Web browsing sessions keep dropping prematurely. Upon investigation, you find that the IDP policy shown in the exhibit is detecting the users#39; sessions as HTTP:WIN-CMD:WIN-CMD-EXE attacks, even though their sessions are not actual attacks. You must allow these sessions but still inspect for all other relevant attacks.

How would you configure your SRX device to meet this goal?

  1. Create a new security policy that allows HTTP for all users and does not apply IDP.

  2. Modify the security policy to add an application exception.

  3. Modify the IDP policy to delete this particular attack from the IDP rulebase.

  4. Modify the IDP policy to add an exempt rulebase rule to not inspect for this attack.

Answer: D

Question No: 35

You are asked to ensure that your IPS engine blocks attacks. You must ensure that your system continues to drop additional malicious traffic without additional IPS processing for up to 30 minutes. You must ensure that the SRX Series device does send a notification packet when the traffic is dropped.

Which statement is correct?

  1. Use the IP-Block action.

  2. Use the Drop Packet action.

  3. Use the Drop Connection action.

  4. Use the IP-Close action.

Answer: D

Question No: 36

You are troubleshooting an IPsec session and see the following IPsec security associations:

ID Gateway Port Algorithm SPI Life:sec/kb Mon vsys

lt; 192.168.224.1 500 ESP:aes-256/sha1 d6393645 26/ unlim – 0

gt; 192.168.224.1 500 ESP:aes-256/sha1 153ec235 26/ unlim – 0

lt; 192.168.224.1 500 ESP:aes-256/sha1 f9a2db9a 3011/ unlim – 0

gt; 192.168.224.1 500 ESP:aes-256/sha1 153ec236 3011/ unlim – 0

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

  1. Both peers are trying to establish IKE Phase 1 but are not successful.

  2. Both peers have established SAs with one another, resulting in two IPsec tunnels.

  3. The lifetime of the Phase 2 negotiation is close to expiration.

  4. Both peers have establish-tunnels immediately configured.

Answer: C,D

Referring to the exhibit, which two statements are true? (Choose two.)

  1. Packets may get fragmented.

  2. The tunnel automatically fragments packets based on MTU discovery.

  3. The Phase 2 association will never expire.

  4. The Phase 2 association will expire without traffic.

Answer: A,D

Question No: 38

Which feature is used for layer 2 bridging on an SRX Series device?

  1. route mode

An attacker is using a nonstandard port for HTTP for reconnaissance into your network. Referring to the exhibit, which two statements are true? (Choose two.)

  1. The IPS engine will not detect the application due to the nonstandard port.

  2. The IPS engine will detect the application regardless of the nonstandard port.

  3. The IPS engine will perform application identification until the session is established.

  4. The IPS engine will perform application identification until it processes the first 256 bytes of the packet.

Answer: B,D

You have configured your SRX device to download and install attack signature updates as shown in the exhibit. You discover that updates are not being downloaded.

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

  1. No security policy is configured to allow the SRX device to contact the update server.

  2. The SRX device does not have a DNS server configured.

  3. The management zone interface does not have an IP address configured.

  4. The SRX device has no Internet connectivity.

Answer: B,D Explanation:

Configuration is correct. Only reason is that SRZ device is not able to connect to definition server.
