Juniper Security, Professional (JNCIP-SEC) Sample Questions (Q40-Q45):

NEW QUESTION # 40
Exhibit

You are using traceoptions to verify NAT session information on your SRX Series device.
Referring to the exhibit, which two statements are correct? (Choose two.)

A. This is the last packet in the session.
B. The SRX Series device is performing only source NAT on this session.
C. The SRX Series device is performing both source and destination NAT on this session.
D. This is the first packet in the session.

Answer: A,C

NEW QUESTION # 41
How does an SRX Series device examine exception traffic?

A. The device examines the host-inbound traffic for the egress interface and zone.
B. The device examines the host-outbound traffic for the egress interface and zone.
C. The device examines the host-inbound traffic for the ingress interface and zone.
D. The device examines the host-outbound traffic for the ingress interface and zone.

Answer: C

Explanation:
Exception traffic, including management and control plane traffic, is handled by examining host- inbound traffic configurations at the ingress interface and zone. It ensures traffic reaches necessary services like SSH and IKE securely.
SRX Series devices handle exception traffic (such as management traffic like SSH, Telnet, DNS queries, etc.) differently than regular transit traffic. Exception traffic is examined based on host- inbound traffic for the ingress interface and zone. If traffic is destined for the device itself (e.g., management traffic or routing protocol messages), it must be allowed as host-inbound traffic on both the ingress interface and zone.

NEW QUESTION # 42
Exhibit:

Your company uses SRX Series devices to establish an IPsec VPN that connects Site-1 and the HQ networks.
You want VoIP traffic to receive priority over data traffic when it is forwarded across the VPN.
Which three actions should you perform in this scenario? (Choose three.)

A. Enable the multi-sa parameter to enable two separate IPsec SAs for the VoIP and data traffic.
B. Enable next-hop tunnel binding.
C. Configure CoS forwarding classes and scheduling parameters.
D. Create a firewall filter that identifies VoIP traffic and associates it with the correct forwarding class.
E. Enable the copy-outer-dscp parameter so that DSCP header values are copied to the tunneled packets.

Answer: B,C,D

Explanation:
In this scenario, you are prioritizing VoIP traffic over data traffic across an IPsec VPN. Here are the necessary actions:
* Enable next-hop tunnel binding (Answer A): This is required to bind the VPN traffic to a specific tunnel interface (like st0.0). It allows differentiated forwarding behavior (like prioritizing VoIP) for specific traffic types.
Command Example:
bash
Copy code
set interfaces st0.0 next-hop-tunnel-service
* Create a firewall filter (Answer B): The filter will match VoIP traffic based on criteria such as DSCP marking or ports (like port 5060 for SIP). Once identified, the traffic will be associated with a forwarding class, ensuring it gets prioritized.
Command Example:
bash
Copy code
set firewall family inet filter VoIP-Filter term VoIP from protocol udp set firewall family inet filter VoIP-Filter term VoIP from port 5060 set firewall family inet filter VoIP-Filter term VoIP then forwarding-class voice
* Configure CoS (Class of Service) forwarding classes (Answer C): CoS parameters define how the SRX handles different types of traffic (scheduling, shaping, etc.). VoIP traffic must be assigned a higher priority than data.
Command Example:
bash
Copy code
set class-of-service forwarding-classes voice
set class-of-service forwarding-classes data
set class-of-service schedulers voice_scheduler transmit-rate percent 50 These configurations ensure that VoIP traffic is identified, classified, and forwarded with priority.

NEW QUESTION # 43
You are asked to establish a hub-and-spoke IPsec VPN using an SRX Series device as the hub.
All of the spoke devices are third-party devices.
Which statement is correct in this scenario?

A. You must always peer using loopback addresses when using non-Junos devices as your spokes.
B. You must statically configure the next-hop tunnel binding table entries for each of the third-party spoke devices.
C. You must ensure that you are using aggressive mode when incorporating third-party devices as your spokes.
D. You must create a policy-based VPN on the hub device when peering with third-party devices.

Answer: B

NEW QUESTION # 44
An ADVPN configuration has been verified on both the hub and spoke devices and it seems fine.
However, OSPF is not functioning as expected.

Referring to the exhibit, which two statements under interface st0.0 on both the hub and spoke devices would solve this problem? (Choose two.)

A. dynamic-neighbors
B. interface-type p2p
C. passive
D. interface-type p2mp

Answer: A,D

Explanation:
For ADVPN with OSPF, using a point-to-multipoint (p2mp) interface type and enabling dynamic- neighbors are crucial. This configuration allows dynamic discovery of neighbors and the establishment of tunnels. For more information, refer to Juniper ADVPN Configuration Guide.
In the ADVPN configuration, OSPF isn't functioning as expected due to the interface configuration on st0.0.
