Which two functions does Juniper ATP Cloud perform to reduce delays in the inspection of files? (Choose two.)
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.
You are implementing an SRX Series device at a branch office that has low bandwidth and also uses a cloud-based VoIP solution with an outbound policy that permits all traffic.
Which service would you implement at your edge device to prioritize VoIP traffic in this scenario?
The service that you would implement at your edge device to prioritize VoIP traffic in this scenario is AppQoS. AppQoS is a feature that enables you to allocate bandwidth and prioritize traffic based on application signatures or custom rules. AppQoS can enhance the quality of service and experience for critical or latency-sensitive applications, such as VoIP. You can configure AppQoS policies to assign different classes of service (CoS) values or queue numbers to different applications or traffic flows. You can also define bandwidth limits, guarantees, or bursts for each class or queue.Reference:= [Application Quality of Service Overview], [Configuring Application Quality of Service]
Which two statements are correct about the fab interface in a chassis cluster? (Choose two.)
The fab interface is a fabric link that connects the two nodes in a chassis cluster. A chassis cluster is a high-availability feature that groups two identical SRX Series devices into a cluster that acts as a single device. The fab interface has two functions:
Real-time objects (RTOs) are exchanged on the fab interface to maintain session synchronization: RTOs are data structures that store information about active sessions, such as source and destination IP addresses, ports, protocols, and security policies. RTOs are exchanged between the nodes on the fab interface to ensure that both nodes have the same session information and can take over the traffic in case of a failover.
In an active/active configuration, inter-chassis transit traffic is sent over the fab interface: In an active/active configuration, both nodes in a cluster can process traffic for different redundancy groups (RGs). RGs are collections of interfaces or services that fail over together from one node to another. If traffic needs to transit from one RG to another RG that is active on a different node, it is sent over the fab interface.
Which two statements are correct about a reth LAG? (Choose two.)
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.
Which two statements are true about Juniper ATP Cloud? (Choose two.)
Two statements that are true about Juniper ATP Cloud are:
Juniper ATP Cloud uses multiple antivirus software packages to analyze files: 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. Juniper ATP Cloud uses multiple antivirus software packages from different vendors to scan files for known malware signatures and provide a comprehensive verdict based on their results.
Juniper ATP Cloud does not use antivirus software packages to protect against zero-day threats: Juniper ATP Cloud protects against zero-day threats by using dynamic analysis, not antivirus software packages. Dynamic analysis is a method of executing files in a sandbox environment and observing their behavior and network interactions. Dynamic analysis can uncover unknown malware that may evade static analysis or signature-based detection methods.
