Juniper Security, Professional (JNCIP-SEC) Sample Questions (Q10-Q15):

NEW QUESTION # 10
SRX Series device enrollment with Policy Enforcer fails To debug further, the user issues the following commandshow configuration services security-intelligence url
https://cloudfeeds.argon.juniperaecurity.net/api/manifeat.xml
and receives the following output:
What is the problem in this scenario?

A. The device is directly enrolled with Juniper ATP Cloud.
B. The device is already enrolled with Policy Enforcer.
C. Junos Space does not have matching schema based on the
D. The SRX Series device does not have a valid license.

Answer: D

NEW QUESTION # 11
Exhibit:

Referring to the flow logs exhibit, which two statements are correct? (Choose two.)

A. The packet is dropped by a configured security policy.
B. The data shown requires a traceoptions flag of host-traffic.
C. The data shown requires a traceoptions flag of basic-datapath.
D. The packet is dropped by the default security policy.

Answer: C,D

Explanation:
* Understanding the Flow Log Output:
From the flow logs in the exhibit, we can observe the following key events:
* The session creation was initiated (flow_first_create_session), but the policy searchfailed (flow_first_policy_search), which implies that no matching policy was found between the zones involved (zone trust-> zone dmz).
* The packet was dropped with the reason "denied by policy." This shows that the packet was dropped either due to no matching security policy or because the default policy denies the traffic (packet dropped, denied by policy).
* The line denied by policy default-policy-logical-system-00(2) indicates that the default security policy is responsible for denying the traffic, confirming that no explicit security policy was configured to allow this traffic.
* Explanation of Answer A (Dropped by the default security policy):
The log message clearly states that the packet was dropped by the default security policy (default-policy- logical-system-00). In Junos, when a session is attempted between two zones and no explicit policy exists to allow the traffic, the default policy is to deny the traffic. This is a common behavior in Junos OS when a security policy does not explicitly allow traffic between zones.
* Explanation of Answer D (Requires traceoptions flag of basic-datapath):
The information displayed in the log involves session creation, flow policy search, and packet dropping due to policy violations, which are all part of basic packet processing in the data path. This type of information is logged when the traceoptions flag is set tobasic-datapath. The basic-datapath traceoption provides detailed information about the forwarding process, including policy lookups and packet drops, which is precisely what we see in the exhibit.
* The traceoptions flaghost-traffic(Answer C) is incorrect because host-traffic is typically used for traffic destined to or generated from the Junos device itself (e.g., SSH or SNMP traffic to the SRX device), not for traffic passing through the device.
* To capture flow processing details like those shown, you need the basic-datapath traceoptions flag, which provides details about packet forwarding and policy evaluation.
Step-by-Step Configuration for Tracing (Basic-Datapath):
* Enable flow traceoptions:
To capture detailed information about how traffic is being processed, including policy lookups and flow session creation, enable traceoptions for the flow.
bash
Copy code
set security flow traceoptions file flow-log
set security flow traceoptions flag basic-datapath
* Apply the configuration and commit:
bash
Copy code
commit
* View the logs:
Once enabled, you can check the trace logs for packet flows, policy lookups, and session creation details:
bash
Copy code
show log flow-log
This log will contain information similar to the exhibit, including session creation attempts and packet drops due to security policy.
Juniper Security Reference:
* Default Security Policies: Juniper SRX devices have a default security policy to deny all traffic that is not explicitly allowed by user-defined policies. This is essential for security best practices. Reference:
Juniper Networks Documentation on Security Policies.
* Traceoptions for Debugging Flows: Using traceoptions is crucial for debugging and understanding how traffic is handled by the SRX, particularly when issues arise from policy misconfigurations or routing. Reference: Juniper Traceoptions.
By using the basic-datapath traceoptions, you can gain insights into how the device processes traffic, including policy lookups, route lookups, and packet drops, as demonstrated in the exhibit.

NEW QUESTION # 12
Which two statements are correct about mixed mode? (Choose two.)

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

Answer: B,C

NEW QUESTION # 13
Your organization has multiple Active Directory domain to control user access. You must ensure that security polices are passing traffic based upon the user's access rights.
What would you use to assist your SRX series devices to accomplish this task?

A. Junos Space
B. JIMS
C. JATP Appliance
D. JSA

Answer: B

Explanation:

NEW QUESTION # 14
Referring to the exhibit,

which three statements about the multinode HA environment are true? (Choose three.)

A. Session state is synchronized on both nodes.
B. Node 2 will process transit traffic that it receives for services redundancy group 1.
C. Two services redundancy groups are available.
D. IP monitoring has failed for the services redundancy group.
E. Node 1 will host services redundancy group 1 unless it is unavailable.

Answer: A,C,E

Explanation:
Referring to the exhibit for a multinode HA environment, we can conclude the following about the HA setup:
* Two Services Redundancy Groups (Correct: Option A):The output shows the status ofSRG 0and SRG 1, confirming that there are two services redundancy groups in the HA configuration.
* Node 1 Hosting SRG 1 (Correct: Option C):The exhibit indicates thatNode 1is currently active for SRG 1. According to the configuration, Node 1 will continue to host SRG 1 unless it becomes unavailable.
* Session State Synchronization (Correct: Option D):In this HA setup, session state synchronization is enabled between the two nodes. This ensures that sessions remain active and seamless failover can occur if one node fails.
Juniper References:
* Juniper HA Documentation: Provides details on multinode HA setups, SRG configurations, and session synchronization.
