You have a multinode HA default mode deployment and the ICL is down.
In this scenario, what are two ways that the SRX Series devices verify the activeness of their peers? (Choose two.)
Answer : A, D
Comprehensive Detailed Step-by-Step Explanation with All Juniper Security Reference
Understanding the Scenario:
Multinode HA Default Mode Deployment:
In a chassis cluster, two SRX devices operate together to provide high availability.
ICL (Inter-Cluster Link) is Down:
The control and fabric links between the nodes are not operational.
Objective:
Determine how the SRX devices verify each other's activeness without the ICL.
Option A: Custom IP addresses may be configured for the activeness probe.
When the control link is down, SRX devices use an ICMP ping-based activeness probe to check the peer's status.
Custom IP addresses can be configured as probe targets to verify the peer's activeness.
'You can configure the SRX Series device to send activeness probes to a configured IP address to verify the peer's state when the control link is down.'
Source: Juniper Networks Documentation - Control Link Failure Detection
Option D: Each peer sends a probe with the virtual IP address as the source IP address and the upstream router as the destination IP address.
The SRX devices send ICMP probes to an upstream device using the redundancy group's virtual IP address as the source.
This helps determine if the peer node is still active by verifying network reachability.
'When the control link fails, each node sends ICMP pings to the configured probe addresses using the redundancy group's virtual IP address as the source.'
Source: Juniper Networks Documentation - Chassis Cluster Control Link Failure
Why Options B and C are Incorrect:
Option B: Fabric link heartbeats cannot be used because the ICL (which includes the fabric link) is down.
Option C: Probes are sent to upstream devices, not using the virtual IP address as the destination.
Conclusion:
The correct options are A and D because they accurately describe how SRX devices verify activeness without the ICL.
Which two elements are necessary to configure a rule under an APBR profile? (Choose Two)
Answer : B, C
Here's why those elements are necessary for configuring a rule under an APBR profile:
B . Match condition: This defines the criteria for matching traffic to the APBR rule. It can include:
Applications: Match based on specific applications or application groups.
URL categories: Match based on URL categories provided by a web filtering service.
Other criteria: You can also match based on source/destination IP addresses, ports, protocols, etc.
C . Then action: This specifies the action to take when traffic matches the rule. The primary action in APBR is:
routing-instance: This redirects the matching traffic to a specific routing instance, allowing you to steer traffic through different paths based on the application or URL category.
Why other options are incorrect:
A . Instance type: While routing instances are used in APBR, the 'instance type' itself is not configured within the APBR rule. You define the instance type separately when configuring the routing instance.
Referring to the exhibit, you are attempting to set up a remote access VPN on your SRX series devices.
However you are unsure of which system services you should allow and in which zones they should be allowed to correctly finish the remote access VPN configuration
Which two statements are correct? (Choose two.)
Answer : A, C
What are three configurable monitor components for a service redundancy group? (Choose two)
Answer : A, D, E
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.)
Answer : A, B
