Juniper Security, Professional (JNCIP-SEC) Sample Questions (Q33-Q38):

NEW QUESTION # 33
Which two statements are correct about automated threat mitigation with Security Director?
(Choose two.)

A. Infected hosts are tracked by their chassis serial number.
B. Infected hosts are tracked by their user identity.
C. Infected hosts are tracked by their MAC address.
D. Infected hosts are tracked by their IP address.

Answer: C,D

NEW QUESTION # 34
Exhibit

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

A. The 3uspicious_Endpoint3 feed is only usable by the SRX-1 device.
B. You must manually create the suspicious_Endpoint3 feed in the Juniper ATP Cloud interface.
C. The 3uspiciou3_Endpoint3 feed is usable by any SRX Series device that is a part of the same realm as SRX-1
D. Juniper ATP Cloud automatically creates the 3uopi'cioua_Endpoints feed after you commit the security policy.

Answer: A,C

NEW QUESTION # 35
The SRX series device is performing static NAT. you want to ensure that host A can reach the internal webserver www.juniper.net using domain name.

Referring to the exhibit, which two Junos features are required to accomplish this task? (Choose two.)

A. proxy ARP
B. persistent NAT
C. STUN
D. DNS doctoring

Answer: A,D

NEW QUESTION # 36
The exhibit shows part of the flow session logs.

Which two statements are true in this scenario? (Choose two.)

A. Destination NAT occurs.
B. The existing session is found in the table, and the fast path process begins.
C. Junos captures a TCP packet from source address 172.20.101.10 destined to 10.0.1.129.
D. This packet arrives on interface ge-0/0/4.0.

Answer: C,D

Explanation:
From the session log, we can derive the following:
* Packet arrives on ge-0/0/4.0 (Answer B): The log indicates that the incoming packet is being processed on the ge-0/0/4.0 interface, as seen in the output.
Example Log Analysis:
ruby
Copy code
CID-0:THREAD_ID-01:RT: chose interface ge-0/0/4.0 as incoming nat if.
* TCP Packet Captured (Answer C): The source of the packet is 172.20.101.10 and it is destined for
10.0.1.129 on port 22, as described in the log.
Example Log Analysis:
ruby
Copy code
CID-0:THREAD_ID-01:RT: CID-0:THREAD_ID-01:RT: flow_first_create_session...
sa 172.20.101.10, da 10.0.1.129, sp 59009, dp 22
These logs show the creation of a session for TCP traffic (likely SSH, based on port 22) between the source and destination addresses across the tunnel.

NEW QUESTION # 37
Which two statements are correct about mixed mode? (Choose two.)

A. IRB interfaces can be used to route traffic.
B. Layer 2 and Layer 3 interfaces can use the same security zone.
C. IRB interfaces cannot be used to route traffic.
D. Layer 2 and Layer 3 interfaces can use separate security zones.

Answer: A,B

Explanation:
In mixed mode, both Layer 2 and Layer 3 interfaces can be configured to operate within the same security zone, allowing for flexible network segmentation. Additionally, Integrated Routing and Bridging (IRB) interfaces facilitate routing for Layer 2 bridged domains, allowing Layer 2 traffic to be forwarded at Layer 3.
For more information on mixed mode and IRB functionality, refer to Juniper's Mixed Mode and IRB Documentation.
* Explanation of Answer A (Layer 2 and Layer 3 in Same Zone):
* Inmixed modeconfigurations, it is possible to have both Layer 2 and Layer 3 interfaces within the same security zone. This allows for flexible design where different types of traffic can be handled by the same set of security policies.
* Explanation of Answer B (IRB Interfaces Can Route Traffic):
* IRB (Integrated Routing and Bridging)interfaces are used to route traffic between Layer 2 and Layer 3 domains. They can bridge traffic at Layer 2 and also provide Layer 3 routing capabilities within the same device. This allows for seamless interaction between Layer 2 and Layer 3 traffic in mixed mode.
Step-by-Step Configuration:
* Configuring Layer 2 and Layer 3 in the Same Security Zone:
* Assign both Layer 2 and Layer 3 interfaces to the same security zone as follows:
bash
Copy code
set security zones security-zone <zone-name> interfaces <interface-name>
* Configuring IRB Interface:
* To route traffic using the IRB interface:
bash
Copy code
set interfaces irb unit 0 family inet address <ip-address>
set security zones security-zone <zone-name> interfaces irb.0
Juniper Security Reference:
* IRB Interface Overview: IRB interfaces allow for both bridging and routing functionalities, making them essential in mixed-mode environments.
* Layer 2 and Layer 3 in the Same Zone: This feature provides flexibility in designingnetworks that combine both Layer 2 switching and Layer 3 routing under the same security policies.
