Explanation
vSRX is a virtual firewall that provides security and networking services at the perimeter or edge of virtualized environments1. vSRX can be deployed in various cloud environments, such as AWS, Azure, Google Cloud Platform, and VMware2.
AWS is a cloud computing platform that offers a variety of services, such as compute, storage, networking, security, and analytics3. AWS enables customers to deploy vSRX instances in a virtual private cloud (VPC), which is a logically isolated section of the AWS cloud4.
AWS satisfies the requirements for a vSRX deployment as follows:
Globally distributed: AWS has a global infrastructure that spans 25 geographic regions and 81 availability zones3. Customers can deploy vSRX instances in any region or zone that meets their needs and preferences4.
Rapid provisioning: AWS allows customers to launch vSRX instances in minutes using the AWS Marketplace, which is an online store that offers software products and solutions5. Customers can also use automation tools, such as CloudFormation, Terraform, and Ansible, to provision vSRX instances in a consistent and scalable manner.
Scale based on demand: AWS supports horizontal and vertical scaling of vSRX instances based on the changing traffic and performance demands. Customers can use AWS Auto Scaling, which is a service that automatically adjusts the number of vSRX instances, or AWS Elastic Load Balancing, which is a service that distributes the traffic across multiple vSRX instances.
Low CapEx: AWS operates on a pay-as-you-go model, which means that customers only pay for the resources they use, such as the vSRX instance type, the storage volume, the data transfer, and the license. Customers can also benefit from the AWS Free Tier, which offers a limited amount of free resources for 12 months.

You want to set up JSA to collect network traffic flows from network devices on your network.
Which two statements are correct when performing this task? (Choose two.)
- A. Statistical sampling decreases event correlation accuracy.
- B. Superflows reduce traffic licensing requirements.
- C. Statistical sampling increases processor utilization
- D. BGP FlowSpec is used to collect traffic flows from Junos OS devices.
正解：A、D
解説：
The two correct statements when performing this task are A.
BGP FlowSpec is used to collect traffic flows from Junos OS devices, and C.
Statistical sampling decreases event correlation accuracy.
BGP FlowSpec is a Junos OS feature that allows network devices to send traffic flow information to a Juniper security device using BGP.
This allows the Juniper security device to monitor and collect the traffic flows and analyze them for suspicious activity.
Statistical sampling increases processor utilization by selecting only a subset of the data to be analyzed, which can help reduce the amount of data sent to the security device.
However, this also decreases the accuracy of event correlation, as some events may be missed due to the sampling. Superflows reduce traffic licensing requirements by offloading the processing of certain traffic flows to the device itself, instead of having it sent to the security device.
質問 # 52
Which two statements are correct about JSA data collection? (Choose two.)
- A. The Event Collector parses logs
- B. The Event Collector collects information using BGP FlowSpec.
- C. The Flow Collector can use statistical sampling
- D. The Flow Collector parses logs.
正解：A、C
解説：
Explanation
Juniper Secure Analytics (JSA) is a security information and event management (SIEM) system that consolidates, analyzes, and manages surveillance data from network devices, endpoints, and applications. JSA uses two types of data collectors: Event Collector and Flow Collector1 The Event Collector collects and parses logs from various log sources, such as firewalls, routers, servers, and intrusion detection or prevention systems. The Event Collector normalizes the log data into a common format and sends it to the JSA console for further analysis and correlation. The Event Collector supports different protocols for log collection, such as syslog, SNMP, JDBC, and SDEE12 The Flow Collector collects and processes network traffic data from various flow sources, such as Flowlog files, NetFlow, J-Flow, sFlow, and Packeteer. The Flow Collector enriches the flow data with additional information, such as application identification, geolocation, and threat intelligence. The Flow Collector sends the flow data to the JSA console for further analysis and correlation. The Flow Collector can use statistical sampling to reduce the amount of flow data that is collected and processed, which can improve the performance and scalability of the system12 The Event Collector does not collect information using BGP FlowSpec, which is a protocol that allows the distribution of traffic flow specification rules among BGP peers. BGP FlowSpec is not a supported flow source for JSA3 The Flow Collector does not parse logs, which are textual records of network activity generated by log sources. The Flow Collector only handles flow data, which are binary records of network traffic generated by flow sources12 References: 1: Data Collection | JSA 7.5.0 | Juniper Networks 2: Data Collection - TechLibrary - Juniper Networks 3: Understanding BGP FlowSpec - TechLibrary - Juniper Networks
質問 # 53
On an SRX Series firewall, what are two ways that Encrypted Traffic Insights assess the threat of the traffic? (Choose two.)
- A. It decrypts the file in a sandbox.
- B. It decrypts the data to validate the hash.
- C. It reviews the timing and frequency of the connections.
- D. It validates the certificates used.
正解：C、D
解説：
Encrypted Traffic Insights is a feature that enables the SRX Series firewall and the ATP Cloud to detect malicious threats that are hidden in encrypted traffic without decrypting the traffic. It does so by analyzing the metadata and connection patterns of the encrypted sessions. Two ways that Encrypted Traffic Insights assess the threat of the traffic are:
It validates the certificates used: The SRX Series firewall extracts the server certificate from the encrypted session and compares its signature with a blocklist of known malicious certificates provided by ATP Cloud. If there is a match, the session is blocked and reported as a threat.
It reviews the timing and frequency of the connections: The SRX Series firewall sends the connection details, such as source and destination IP addresses, ports, protocols, and timestamps, to ATP Cloud. ATP Cloud applies behavior analysis and machine learning algorithms to detect anomalous or suspicious patterns of connections, such as high frequency, low duration, or unusual timing.
質問 # 54
Which solution enables you to create security policies that include user and group information?
- A. JIMS
- B. NETCONF
- C. Network Director
- D. ATP Appliance
正解：A
解説：
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.

質問 # 56
What information does encrypted traffic insights (ETI) use to notify SRX Series devices about known malware sites?
- A. domain names
- B. certificates
- C. dynamic address groups
- D. MAC addresses
正解：A
解説：
Encrypted traffic insights (ETI) uses domain names to notify SRX Series devices about known malware sites. ETI is a feature of the SRX Series firewall that can detect and block malware that is hidden in encrypted traffic. It works by analyzing the domain names of the websites that the encrypted traffic is attempting to access. If the domain name matches a known malware site, ETI will send an alert to the SRX Series device, which can then take appropriate action to block the traffic. ETI is a useful tool for protecting against threats that attempt to evade detection by hiding in encrypted traffic.
