Which two statements are correct about a reth LAG? (Choose two.)
- A. You should have two or more interfaces.
- B. You must have a "minimum-links" statement value of two.
- C. Links must have the same speed and duplex setting.
- D. Links must use the same cable type
Answer: A,C
Explanation:
A reth LAG is a redundant Ethernet link aggregation group that combines multiple physical interfaces into a single logical interface in a chassis cluster. A reth LAG provides load balancing and redundancy for traffic within or between redundancy groups. Two statements that are correct about a reth LAG are:
Links must have the same speed and duplex setting: To form a reth LAG, the physical interfaces must have the same speed and duplex setting. This ensures that the links can operate at the same capacity and avoid performance issues or errors.
You should have two or more interfaces: To create a reth LAG, you need to have at least two physical interfaces. One interface should be connected to node 0 and the other interface should be connected to node 1. You can also have more than two interfaces in a reth LAG for increased bandwidth and redundancy.

NEW QUESTION # 20
You want to manually failover the primary Routing Engine in an SRX Series high availability cluster pair.
Which step is necessary to accomplish this task?
- A. Manually request the failover and identify the secondary node
- B. Adjust the priority in the configuration on the secondary node.
- C. Issue the set chassis cluster disable reboot command on the primary node.
- D. Implement the control link recover/ solution before adjusting the priorities.
Answer: A
Explanation:
This step involves issuing a command to manually initiate a failover from the primary Routing Engine to the secondary. This can typically be done using a command like request chassis cluster failover redundancy-group <group-number> node <node-id>, where <group-number> is the redundancy group you are failing over, and <node-id> specifies the node to which you want to failover (usually the secondary node). This command forces the designated node to take over as primary for the specified redundancy group.
NEW QUESTION # 21
Which solution enables you to create security policies that include user and group information?
- A. Network Director
- B. JIMS
- C. ATP Appliance
- D. NETCONF
Answer: B
Explanation:
The solution that enables you to create security policies that include user and group information is JIMS (Juniper Identity Management Service). JIMS collects and maintains a large database of user, device, and group information from Active Directory domains or syslog sources, and enables SRX Series devices to rapidly identify thousands of users in a large, distributed enterprise. With JIMS, you can create security policies that include user and group information, and enforce user-based access control policies to protect network resources.
NEW QUESTION # 22
Your network uses a single JSA host and you want to implement a cluster.
In this scenario, which two statements are correct? (Choose two.)
- A. The software versions on both primary and secondary hosts
- B. The primary and secondary hosts must be configured with the same storage devices.
- C. The secondary host can backup multiple JSA primary hosts.
- D. The cluster virtual IP will need an unused IP address assigned.
Answer: A,D
Explanation:
According to the Juniper Networks JNCIP-SEC Study Guide, when setting up a cluster with a single JSA host, both the primary and secondary hosts must have the same software version installed. Additionally, an unused IP address must be assigned to the cluster virtual IP. The primary and secondary hosts do not need to be configured with the same storage devices, and the secondary host cannot be used to backup multiple JSA primary hosts.
NEW QUESTION # 23
You are asked to ensure that if the session table on your SRX Series device gets close to exhausting its resources, that you enforce a more aggress.ve age-out of existing flows.
In this scenario, which two statements are correct? (Choose two.)
- A. The high-watermark configuration specifies the percentage of how much of the session table is left before disabling a more aggressive age- out timer.
- B. The early-ageout configuration specifies the timeout value, in seconds, that will be applied once the low-watermark value is met.
- C. The high-watermark configuration specifies the percentage of how much of the session table can be allocated before applying a more aggressive age-out timer
- D. The early-ageout configuration specifies the timeout value, in seconds, that will be applied once the high-watermark value is met.
Answer: C,D
Explanation:
The early-ageout configuration specifies the timeout value, in seconds, that will be applied once the high- watermark value is met. The high-watermark configuration specifies the percentage of how much of the session table can be allocated before applying a more aggressive age-out timer. This ensures that the session table does not become full and cause traffic issues, and also ensures that existing flows are aged out quickly when the table begins to get close to being full.
NEW QUESTION # 24
Exhibit
You are trying to create a security policy on your SRX Series device that permits HTTP traffic from your private 172 25.11.0/24 subnet to the Internet You create a policy named permit-http between the trust and untrust zones that permits HTTP traffic. When you issue a commit command to apply the configuration changes, the commit fails with the error shown in the exhibit.
Which two actions would correct the error? (Choose two.)
- A. Create a custom application named http at the [edit applications] hierarchy.
- B. Modify the security policy to use the built-in Junos-http applications.
- C. Issue the rollback 1 command from the top of the configuration hierarchy and attempt the commit again.
- D. Execute the Junos commit full command to override the error and apply the configuration.
Answer: A,B
Explanation:
The error message indicates that the Junos-http application is not defined, so you need to either create a custom application or modify the security policy to use the built-in Junos-http application. Doing either of these will allow you to successfully commit the configuration.
NEW QUESTION # 25
Exhibit
Referring to the exhibit, which two statements describe the type of proxy used? (Choose two.)
- A. forward proxy
- B. client protection proxy
- C. reverse proxy
- D. server protection proxy
Answer: A,C
Explanation:
In the exhibit, the SRX Firewall could be acting as a forward proxy, managing outbound internet requests from internal users or clients within a private network to the internet. Forward proxies are commonly used to control and monitor outbound traffic, provide content caching to improve load times, and enforce company policies.
The scenario can also imply a reverse proxy setup where the SRX Firewall might be configured to direct incoming requests from the internet to the web application. Reverse proxies are used to balance load, enhance security, manage SSL encryption, and provide additional caching functionalities for inbound traffic to servers.

You want to show tabular data for operational mode commands.
In this scenario, which logging parameter will provide this function?
- A. permit
- B. session-close
- C. count
- D. session-init
Answer: C
Explanation:
The logging parameter that will provide the function of showing tabular data for operational mode commands is count. The count parameter displays the number of packets and bytes that match a security policy and the action taken by the policy. The count parameter can be used with the show security policies hit-count command to display the policy counters in a tabular format. The count parameter can also be used with the show security flow session command to display the session counters in a tabular format. Reference: = show security policies hit-count, show security flow session
NEW QUESTION # 27
Which two statements about SRX Series device chassis clusters are true? (Choose two.)
- A. Chassis cluster member devices must be the same model.
- B. Redundancy group 0 is only active on the cluster backup node.
- C. Each chassis cluster member requires a unique cluster ID value.
- D. Each chassis cluster member device can host active redundancy groups
Answer: A,D
Explanation:
In a chassis cluster, both nodes can host active redundancy groups. The active redundancy groups can be distributed between the two nodes, depending on the configuration and failover status, allowing each node to handle traffic for different sets of services or interfaces.
For the chassis clustering to function correctly, both nodes in the cluster must be of the same model.
This requirement ensures that the hardware capabilities, such as processing power and interface compatibility, are identical, which is crucial for maintaining consistent performance and behavior between cluster nodes.
NEW QUESTION # 28
Which two functions does Juniper ATP Cloud perform to reduce delays in the inspection of files?
(Choose two.)
- A. Juniper ATP Cloud allows the creation of allowlists.
- B. Juniper ATP Cloud performs a cache lookup on files.
- C. Juniper ATP Cloud uses a single antivirus software package to analyze files.
- D. Juniper ATP Cloud allows end users to bypass the inspection of files.
Answer: A,B
Explanation:
Juniper ATP Cloud is a cloud-based service that provides advanced threat prevention and detection for your network. It integrates with SRX Series firewalls and MX Series routers to analyze files and network traffic for signs of malicious activity.
Two functions that Juniper ATP Cloud performs to reduce delays in the inspection of files are:
Juniper ATP Cloud allows the creation of allowlists: Allowlists are lists of trusted files or file hashes that are excluded from scanning by Juniper ATP Cloud. You can create allowlists based on file name, file type, file size, file hash, or sender domain. By using allowlists, you can reduce the number of files that need to be uploaded to Juniper ATP Cloud for analysis and improve the performance and efficiency of your network.
Juniper ATP Cloud performs a cache lookup on files: Cache lookup is a process that checks if a file has been previously scanned by Juniper ATP Cloud and if there is a cached verdict for it. If there is a cached verdict, Juniper ATP Cloud returns it immediately without scanning the file again. If there is no cached verdict, Juniper ATP Cloud uploads the file for analysis. By using cache lookup, you can reduce the time and bandwidth required for scanning files by Juniper ATP Cloud.

NEW QUESTION # 30
You want to control when cluster failovers occur.
In this scenario, which two specific parameters would you configure on an SRX Series device? (Choose two.)
- A. heartbeat-address
- B. heartbeat-cos
- C. heartbeat-threshold
- D. heartbeat-interval
Answer: C,D
Explanation:
To control when cluster failovers occur, you need to configure two specific parameters on an SRX Series device: heartbeat-interval and heartbeat-threshold. These parameters determine how often the nodes in a cluster exchange heartbeat messages and how many consecutive heartbeats can be missed before a failover is triggered. The heartbeat-interval specifies the time interval in seconds between each heartbeat message. The default value is 1 second and the range is from 0.1 to 10 seconds. The heartbeat- threshold specifies the number of consecutive heartbeats that must be missed before a failover occurs.
The default value is 3 and the range is from 2 to 255.

NEW QUESTION # 31
Which two statements are correct about SSL proxy server protection? (Choose two.)
- A. You must load the server certificates on the SRX Series device.
- B. You must import the root CA on the servers.
- C. You do not need to configure the servers to use the SSL proxy the function on the SRX Series device.
- D. The servers must be configured to use the SSL proxy function on the SRX Series device.
Answer: A,C
Explanation:
When using SSL proxy, the servers themselves do not require any special configuration to utilize the SSL proxy function on the SRX device. The SSL proxy operates transparently, intercepting and decrypting SSL/TLS traffic before it reaches the servers.
For the SSL proxy to function effectively, especially in server protection mode where it impersonates the server to the client, it is necessary to load the server's certificates onto the SRX device. This allows the SRX to establish a trusted connection with the client using the server's credentials.
NEW QUESTION # 32
Which statement defines the function of an Application Layer Gateway (ALG)?
- A. The ALG uses software that is used by a single TCP session using the same port numbers as the application.
- B. The ALG uses software processes for managing specific protocols.
- C. The ALG uses software processes for permitting or disallowing specific IP address ranges.
- D. The ALG contains protocols that use one application session for each TCP session.
Answer: B
Explanation:
The statement that defines the function of an Application Layer Gateway (ALG) is: The ALG uses software processes for managing specific protocols. An ALG is a security component that operates at the application layer (layer 7) of the OSI model and handles data associated with certain application protocols, such as SIP, FTP, RTSP, etc. An ALG acts as a proxy or intermediary between the client and the server applications and performs various functions, such as address and port translation, resource allocation, application response control, and synchronization of data and control traffic. An ALG can also inspect and modify the application payload to enable firewall or NAT traversal, prevent spoofing or DoS attacks, or enforce granular security policies based on application-specific commands.

After JSA receives external events and flows, which two steps occur? (Choose two.)
- A. Before the information is filtered, the information is formatted
- B. After the information is filtered, JSA responds with active measures
- C. After formatting the data, the data is stored in an asset database.
- D. Before formatting the data, the data is analyzed for relevant information.
Answer: A,C
Explanation:
When JSA (Juniper Secure Analytics) receives external events and flows, the typical processing steps are:
Option C. Before the information is filtered, the information is formatted.
Data formatting is an initial step in the process where raw data from events and flows is converted into a standard format that can be more easily processed and analyzed by JSA.
Option A. After formatting the data, the data is stored in an asset database.
Once the data is formatted, it is stored in an asset database. This database acts as a repository for all the formatted data, enabling JSA to perform further analysis, correlation, and eventually, to maintain a comprehensive view of the network assets and activities.
These steps are part of JSA's comprehensive approach to security event management, which involves collecting, normalizing, and analyzing data to identify potential security threats and vulnerabilities efficiently.
