正解：B、D

解説：
The two statements that are correct about the cSRX are that it supports firewall, NAT, IPS, and UTM services, and that it has three default zones: trust, untrust, and management. The cSRX is a software-defined security solution that provides comprehensive network security capabilities and is designed for virtualized environments. It supports firewall, NAT, IPS, and UTM services to protect against threats, as well as BGP, OSPF, and IS-IS routing services for routing functionality. Additionally, the cSRX has three default zones: trust, untrust, and management. The trust zone is used to define traffic that is allowed to enter the network, the untrust zone is used to define traffic that should be blocked from entering the network, and the management zone is used to manage the device itself. The cSRX does not support Layer 2 "bump-in-the-wire" deployments.

質問 # 69
You want to be alerted if the wrong password is used more than three times on a single device within five minutes.
Which Juniper Networks solution will accomplish this task?

A. Juniper Identity Management Service
B. Intrusion Prevention System
C. Juniper Secure Analytics
D. Adaptive Threat Profiling

正解：C

解説：
Explanation
The Juniper Networks solution that will accomplish the task of alerting if the wrong password is used more than three times on a single device within five minutes is Juniper Secure Analytics (JSA). JSA is a security intelligence platform that collects, analyzes, and correlates network data from various sources, such as firewalls, routers, switches, servers, and applications. JSA can detect and respond to threats, anomalies, and vulnerabilities in real time using rules, offenses, reports, and dashboards. JSA can also integrate with JIMS (Juniper Identity Management Service) to obtain user identity information from Active Directory domains or syslog sources. JSA can use this information to create custom rules that trigger offenses or alerts based on user behavior or activity, such as failed login attempts or password changes.

質問 # 71
Which two statements are correct about chassis clustering? (Choose two.)

A. The cluster ID is used to identify each device in the chassis cluster.
B. A system reboot is required to activate changes to the cluster.
C. The node ID value ranges from 1 to 255.
D. The node ID is used to identify each device in the chassis cluster.

正解：B、D

解説：
In a chassis cluster, each device is assigned a unique node ID. This node ID is used to differentiate between the devices and is crucial for cluster operation and management.
A system reboot is required to activate changes to the cluster: In many cases, changes to the chassis cluster configuration, such as adding or removing nodes, changing redundancy group assignments, or modifying cluster settings, require a system reboot to activate the changes. This reboot ensures that the cluster operates with the updated configuration.

A. infinite number of interfaces
B. scalability
C. granular security
D. no required software license

正解：B、C

解説：
Explanation
= The vSRX is a virtual firewall that offers the same features as the physical SRX Series firewalls, but in a virtualized form factor for delivering security services that scale to match network demand. The vSRX supports Juniper Contrail Networking and third-party software-defined networking (SDN) solutions, which enable dynamic and automated network provisioning and management. The vSRX also integrates with cloud orchestration tools such as OpenStack, which allow for flexible deployment and configuration of virtual machines and networks. The vSRX provides granular security for the workloads that run within the virtual network on the public or private cloud. It supports next-generation firewall capabilities, such as application security, intrusion prevention, user identity, and role-based access control. It also supports advanced threat prevention features, such as malware sandboxing, threat intelligence feeds, and encrypted traffic inspection.
The vSRX can protect the network from both internal and external threats, and enforce consistent security policies across the entire network. References:

Two possible reasons for this error are that the SSL proxy certificate ID does not exist, or the SSL proxy certificate ID is part of a blocklist. If the SSL proxy certificate ID does not exist, you will need to generate a new certificate. If the SSL proxy certificate ID is part of a blocklist, you will need to contact the source of the blocklist to remove it. Additionally, you may need to check that the SSL proxy certificate ID has the correct renegotiation option set, as this is necessary for proper server protection.

質問 # 74
Which two statements are correct about chassis clustering? (Choose two.)

A. A system reboot is required to activate changes to the cluster.
B. The cluster ID is used to identify each device in the chassis cluster.
C. The node ID value ranges from 1 to 255.
D. The node ID is used to identify each device in the chassis cluster.

正解：C、D

解説：
The node ID value ranges from 1 to 255 and is used to identify each device in the chassis cluster.
The cluster ID is also used to identify each device, but it is not part of the node ID configuration. A system reboot is not required to activate changes to the cluster, but it is recommended to ensure that all changes are applied properly.

質問 # 76
Which two statements about the DNS ALG are correct? (Choose two.)

A. The DNS ALG does not support NAT.
B. The DNS ALG supports DDNS.
C. The DNS ALG supports VPN tunnels.
D. The DNS ALG performs DNS doctoring.

正解：B、D

解説：
The DNS ALG is an application layer gateway that handles data associated with locating and translating domain names into IP addresses. It runs on port 53 and monitors DNS query and reply packets. Two statements about the DNS ALG that are correct are:
The DNS ALG supports DDNS: DDNS is Dynamic DNS, which is a method of updating DNS records in real time to reflect changes in network configurations or hostnames. The DNS ALG can process DDNS messages differently from DNS messages and perform address translation in the query part of the message.
The DNS ALG performs DNS doctoring: DNS doctoring is a technique of modifying the DNS reply packets to replace the original IP addresses with translated IP addresses that are suitable for the destination network. This allows the clients to access servers that are located behind NAT devices or in different networks.

質問 # 77

質問 # 78
What are two benefits of using a vSRX in a software-defined network? (Choose two.)

A. infinite number of interfaces
B. scalability
C. granular security
D. no required software license

正解：B、C

解説：
Scalability: vSRX instances can be easily added or removed as the needs of the network change, making it a flexible option for scaling in a software-defined network. Granular Security: vSRX allows for granular security policies to be enforced at the virtual interface level, making it an effective solution for securing traffic in a software-defined network.
The two benefits of using a vSRX in a software-defined network are scalability and granular security. Scalability allows you to increase the number of resources available to meet the demands of network traffic, while granular security provides a level of control and flexibility to your network security that is not possible with a traditional firewall. With a vSRX, you can create multiple levels of security policies, rules, and access control lists to ensure that only authorized traffic can enter and exit your network. Additionally, you would not require a software license to use the vSRX, making it an economical solution for those looking for increased security and flexibility.

質問 # 79

質問 # 80
You are asked to create an IPS-exempt rule base to eliminate false positives from happening.
Which two configuration parameters are available to exclude traffic from being examined? (Choose two.)

A. source port
B. source IP address
C. destination port
D. destination IP address

正解：B

質問 # 81
How does the SSL proxy detect if encryption is being used?

A. It looks at the destination port number.
B. It verifies the length of the packet
C. It uses application identity services.
D. It queries the client device.

正解：A

解説：
The SSL proxy can detect if encryption is being used by looking at the destination port number of the packet. If the port number is 443, then the proxy can assume that the packet is being sent over an encrypted connection. If the port number is different, then the proxy can assume that the packet is not encrypted.
The SSL proxy is a security feature that provides visibility and control over SSL/TLS encrypted traffic. When SSL proxy is enabled, it intercepts SSL/TLS traffic and decrypts it to allow visibility into the content of the encrypted traffic. However, before decrypting the traffic, the SSL proxy must first determine if the traffic is encrypted.
To detect if encryption is being used, the SSL proxy looks at the destination port number. If the destination port number is a known SSL/TLS port (e.g., TCP port 443), the SSL proxy assumes that encryption is being used and intercepts the traffic. If the destination port is not a known SSL/TLS port, the SSL proxy does not intercept the traffic and allows it to pass through the device unmodified.
