Which two statements about SRX chassis clustering are correct? (Choose two.)
Correct Answer: A,C
Explanation SRX chassis clustering is a high availability feature that allows two SRX Series devices to operate as a single logical device. The two devices are connected by a control link and a fabric link, which are used to synchronize the configuration, state, and traffic between the nodes. The control plane is responsible for managing the cluster configuration, monitoring the health and status of the nodes, and performing failover operations. The data plane is responsible for processing and forwarding the traffic through the cluster. SRX chassis clustering supports two modes for the data plane: active/passive and active/active. In active/passive mode, only one node is active for each redundancy group, which is a logical grouping of interfaces and services. The active node handles all the traffic for the redundancy group, while the passive node acts as a backup. In active/active mode, both nodes are active for different redundancy groups, and they can share the traffic load for the cluster. SRX chassis clustering supports only one mode for the control plane: active/passive. In this mode, only one node is the primary node, which is the master of the cluster configuration and the source of truth for the cluster state. The primary node also initiates the failover process in case of a node or interface failure. The other node is the secondary node, which is the slave of the cluster configuration and the backup of the cluster state. The secondary node takes over the primary role if the primary node fails or is manually disabled.

Question 77
Click the Exhibit button. You are validating the configuration template for device access. The commands in the exhibit have been entered to secure IP access to an SRX Series device. Referring to the exhibit, which two statements are true? (Choose two.)
Correct Answer: B,D
The commands in the exhibit show how to configure a firewall filter on the loopback interface (lo0) of an SRX Series device. The loopback interface is a gateway for all the control traffic that enters the Routing Engine of the device. The firewall filter can be used to monitor and protect this control traffic from various attacks. Two statements that are true based on the exhibit are: The loopback interface blocks invalid traffic on its entry into the device: The firewall filter applied on lo0 has a term that matches any packet with an invalid source address (such as 0.0.0.0/8 or 127.0.0.0/8) and discards it. This prevents spoofing or DoS attacks using invalid source addresses. The device manager can access the device from 10.253.1.2: The firewall filter applied on lo0 has a term that matches any packet with a source address of 10.253.1.2 and accepts it. This allows the device manager to access the device from this IP address using protocols such as SSH, Telnet, HTTP, or HTTPS.
Question 78
When working with network events on a Juniper Secure Analytics device, flow records come from which source?
Exhibit Using the information from the exhibit, which statement is correct?
Correct Answer: B
Explanation Based on the information from the exhibit, node0 is the primary node for both redundancy group 0 (RG0) and redundancy group 1 (RG1). RG0 is responsible for the control plane, which includes the Routing Engine and the management interface. RG1 is responsible for the data plane, which includes the interfaces and services. Therefore, node0 is the active node for the data plane, and node1 is the active node for the control plane34 References: Chassis Cluster Redundancy Groups | Junos OS | Juniper Networks Troubleshooting a Redundancy Group that Does Not Fail Over in an SRX Chassis Cluster | Junos OS | Juniper Networks Understanding Chassis Cluster Redundancy Group 0: Routing Engines | Junos OS | Juniper Networks Understanding Chassis Cluster Redundancy Groups 1 Through 128 | Junos OS | Juniper Networks
Question 80
Your company is using the Juniper ATP Cloud free model. The current inspection profile is set at 10 MB You are asked to configure ATP Cloud so that executable files up to 30 MB can be scanned while at the same time minimizing the change in scan time for other file types. Which configuration should you use in this scenario?
Correct Answer: D
In this scenario, you should use the ATP Cloud Ul to create a custom profile and update the scan limit for executable files to 30 MB. This will ensure that executable files up to 30 MB can be scanned, while at the same time minimizing the change in scan time for other file types. To do this, log in to the ATP Cloud Ul and go to the Profiles tab. Click the Create button to create a new profile, and then adjust the scan limits for executable files to 30 MB. Once you have saved the custom profile, you can apply it to the desired systems and the new scan limit will be in effect.
