NEW QUESTION 116
You are enabling advanced policy-based routing. You have configured a static route that has a next hop from the inet.0 routing table. Unfortunately, this static route is not active in your routing instance. In this scenario, which solution is needed to use this next hop?
A. Use RIB groups.
B. Use filter-based forwarding.
C. Use transparent mode.
D. Use policies.
Answer: A
Explanation:
To enable advanced policy-based routing in Junos OS and activate a static route with a next-hop address in the inet.0 table within your routing instance, you should utilize RIB groups. RIB groups allow you to import routes from one routing table to another. In this scenario, the static route within the routing instance needs access to the inet.0 routes, which is facilitated by configuring a RIB group.
NEW QUESTION 117
What are three core components for enabling advanced policy-based routing? (Choose three.)
A. Filter-based forwarding.
B. Routing options.
C. Routing instance.
D. APBR profile.
E. Policies.
Answer: ACD
Explanation:
To enable Advanced Policy-Based Routing (APBR) on SRX Series devices, three key components are necessary: filter-based forwarding, routing instances, and APBR profiles. Filter-based forwarding is utilized to direct specific traffic flows to a routing instance based on criteria set by a policy. Routing instances allow the traffic to be managed independently of the main routing table, and APBR profiles define how and when traffic should be forwarded. These elements ensure that APBR is flexible and tailored to the network’s requirements.
NEW QUESTION 118
You want to bypass IDP for traffic destined to social media sites using APBR, but it is not working and IDP is dropping the session. What are two reasons for this problem? (Choose two.)
A. The session did not properly reclassify midstream to the correct APBR rule.
B. IDP disable is not configured on the APBR rule.
C. The application services bypass is not configured on the APBR rule.
D. The APBR rule does a match on the first packet.
Answer: AC
Explanation:
APBR (Advanced Policy-Based Routing) requires the session to be classified based on the specified rule, which can change midstream as additional packets are processed. If the session was already established before the APBR rule took effect, the traffic may not be correctly reclassified to match the new APBR rule, leading to IDP (Intrusion Detection and Prevention) processing instead of being bypassed. This can occur especially when the session was already established before the rule change. For APBR to work and bypass the IDP service, the application services bypass must be explicitly configured. Without this configuration, the APBR rule may redirect the traffic, but the IDP service will still inspect and potentially drop the traffic. This is especially important for traffic destined for specific sites like social media platforms where bypassing IDP is desired.
NEW QUESTION 119
You configure two Ethernet interfaces on your SRX Series device as Layer 2 interfaces and add them to the same VLAN. The SRX is using the default L2-learning setting. You do not add the interfaces to a security zone. Which two statements are true in this scenario? (Choose two.)
A. You are unable to apply stateful security features to traffic that is switched between the two interfaces.
B. You are able to apply stateful security features to traffic that enters and exits the VLAN.
C. The interfaces will not forward traffic by default.
D. You cannot add Layer 2 interfaces to a security zone.
Answer: AC
Explanation:
When Ethernet interfaces are configured as Layer 2 and added to the same VLAN without being assigned to a security zone, they will not forward traffic by default. Additionally, because they are operating in a pure Layer 2 switching mode, they lack the capability to enforce stateful security policies. When two interfaces are configured as Layer 2 interfaces and belong to the same VLAN but are not assigned to any security zone, traffic switched between them is handled purely at Layer 2. Stateful security features, such as firewall policies, are applied at Layer 3, so traffic between these interfaces will not undergo any stateful inspection or firewalling by default. In Junos, Layer 2 interfaces must be added to a security zone to allow traffic forwarding. Since the interfaces in this scenario are not part of a security zone, they will not forward traffic by default until assigned to a zone. This is a security measure to prevent unintended forwarding of traffic.
NEW QUESTION 120
You have an initial setup of ADVPN with two spokes and a hub. A host at partner Spoke-1 is sending traffic to a host at partner Spoke-2. In this scenario, which statement is true?
A. Spoke-1 will establish a VPN to Spoke-2 when this is first deployed, so traffic will be sent immediately to Spoke-2.
B. Spoke-1 will send the traffic through the hub and not use a direct VPN to Spoke-2.
C. Spoke-1 will establish the tunnel to Spoke-2 before sending any of the host traffic.
D. Spoke-1 will send the traffic destined to Spoke-2 through the hub until the VPN is established between the spokes.
Answer: A
NEW QUESTION 121
How does an SRX Series device examine exception traffic?
A. The device examines the host-inbound traffic for the ingress interface and zone.
B. The device examines the host-outbound traffic for the ingress interface and zone.
C. The device examines the host-inbound traffic for the egress interface and zone.
D. The device examines the host-outbound traffic for the egress interface and zone.
Answer: A
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 122
You want to test how the device handles a theoretical session without generating traffic on the Junos security device. Which command is used in this scenario?
A. request security policies check
B. show security flow session
C. show security match-policies
D. show security policies
Answer: A
Explanation:
The request security policies check command allows you to simulate a session through the SRX device, checking the security policy action that would apply without needing to send real traffic. This helps in validating configurations before actual deployment. The command request security policies check is used to test how a Junos security device handles a theoretical session without generating actual traffic. This command is useful for validating how security policies would be applied to a session based on various parameters like source and destination addresses, application type, and more. This command allows you to simulate a session and verify which security policies would be applied to the session. It’s a proactive method to test security policy configurations without the need to generate real traffic.
