NEW QUESTION # 46
What are three capabilities of AppQoS? (Choose three.)
- A. re-write DSCP values
- B. rate-limit traffic
- C. re-write the TTL
- D. assign a forwarding class
- E. reserve bandwidth
Answer: A,B,D
Explanation:
Explanation
AppQoS is a feature that enables you to identify and control access to specific applications and provides the granularity of the stateful firewall rule base to match and enforce quality of service (QoS) at the application layer. AppQoS expands the capability of Junos OS class of service (CoS) to include the following capabilities12:
Re-write DSCP values based on Layer-7 application types. DSCP values are used to convey the packet's quality of service through both the forwarding class and a loss priority.
Assign a forwarding class based on the application type. Forwarding classes are used to group packets with similar QoS requirements and map them to output queues on the egress interface.
Rate-limit traffic based on the application type. Rate limiters are used to control the transmission speed and volume for the associated queues. You can configure rate limiters and profiles to specify the bandwidth, burst size, and action for each application type.
AppQoS does not have the capability to re-write the TTL or reserve bandwidth. Re-writing the TTL is not related to QoS and could cause routing loops or packet drops. Reserving bandwidth is a function of traffic engineering, not AppQoS. References:

NEW QUESTION # 48
Your JIMS server is unable to view event logs.
Which two actions would you take to solve this issue? (Choose two.)
- A. Enable remote event log management within Windows Firewall on the necessary domain controllers.
- B. Enable remote event log management within Windows Firewall on the necessary Exchange servers.
- C. Enable the correct host-inbound-traffic rules on the SRX Series devices.
- D. Enable remote event log management within Windows Firewall on the JIMS server.
Answer: A,B
Explanation:
If your JIMS server is unable to view event logs, two actions that you would take to solve this issue are:
Enable remote event log management within Windows Firewall on the necessary Exchange servers: JIMS (Juniper Identity Management Service) is a Windows service that collects user, device, and group information from Active Directory domains or syslog sources and provides it to SRX Series devices for identity-based security policies. JIMS relies on the event logs generated by the domain controllers and Exchange servers to track user logins, logouts, and IP address changes. If the Windows Firewall on the Exchange servers blocks the remote event log management, JIMS cannot access the event logs and obtain the user identity information. Therefore, you need to enable remote event log management within Windows Firewall on the Exchange servers that are configured as event sources in JIMS.
Enable remote event log management within Windows Firewall on the necessary domain controllers: Similarly, if the Windows Firewall on the domain controllers blocks the remote event log management, JIMS cannot access the event logs and obtain the user identity information. Therefore, you need to enable remote event log management within Windows Firewall on the domain controllers that are configured as event sources in JIMS.

NEW QUESTION # 50
Which two statements about unified security policies are correct? (Choose two.)
- A. APPID results are used to determine the final security policy
- B. Unified security policies are evaluated after global security policies.
- C. Unified security policies require an advanced feature license.
- D. Traffic can initially match multiple unified security policies.
Answer: A,D
Explanation:
Explanation
Unified policies are security policies that enable you to use dynamic applications as match conditions along with the existing 5-tuple or 6-tuple (with user firewall) match conditions to detect application changes over time3 If the traffic matches the security policy rule, one or more actions defined in the policy are applied to the traffic3 During the initial policy lookup phase, which occurs prior to a dynamic application being identified, if there are multiple policies in the potential policy list, the SRX Series Firewall applies the default security policy until a more explicit match has occurred2 The policy that best matches the application is the final policy2 APPID results are used to determine the final security policy1 References:

NEW QUESTION # 52
Which two statements about the DNS ALG are correct? (Choose two.)
- A. The DNS ALG performs DNS doctoring.
- B. The DNS ALG supports VPN tunnels.
- C. The DNS ALG does not support NAT.
- D. The DNS ALG supports DDNS.
Answer: A,D
Explanation:
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.

Which two statements are correct about Juniper ATP Cloud? (Choose two.)
- A. The threat levels range from 0-10.
- B. The threat levels range from 0-100.
- C. Once the target threshold is met, Juniper ATP Cloud continues looking for threats from 0 to 5 minutes.
- D. Once the target threshold is met, Juniper ATP Cloud continues looking for threats levels range from 0 to 10 minutes.
Answer: A,C
Explanation:
According to the Juniper Networks JNCIS-SEC Study Guide, Juniper ATP Cloud sets target thresholds for security events and then continuously scans the environment for any activity that exceeds this threshold. Once the threshold is met, Juniper ATP Cloud continues looking for threats for a period of 0 to 5 minutes. The threat levels range from 0 to 10, with 0 being the lowest and 10 being the highest.
NEW QUESTION # 54
Which two statements are true about Juniper ATP Cloud? (Choose two.)
- A. Dynamic analysis is always performed to determine if a file contains malware.
- B. If the cache lookup determines that a file contains malware, static analysis is not performed to verify the results.
- C. Dynamic analysis is not always necessary to determine if a file contains malware.
- D. If the cache lookup determines that a file contains malware, performed to verify the results.
Answer: B,C
Explanation:
Explanation
Juniper ATP Cloud is a cloud-based threat detection service that protects all hosts in your network against evolving security threats. It uses a combination of tools to identify and block malware, such as cache lookup, static analysis, and dynamic analysis12 Cache lookup is the first step in the malware detection process. It checks the file hash against a database of known malicious and benign files. If the file is found in the cache, the analysis is completed and the file is either allowed or blocked based on the cache result12 Static analysis is the second step in the malware detection process. It examines the file attributes, such as file size, file type, file name, and embedded URLs, to determine if the file is suspicious or not. If the file is deemed suspicious, it is sent to the next step for further analysis. If the file is deemed benign, it is allowed to pass through12 Dynamic analysis is the third and final step in the malware detection process. It executes the file in a sandbox environment and observes its behavior, such as network connections, registry changes, file operations, and process injections. If the file exhibits malicious behavior, it is blocked and reported. If the file does not exhibit malicious behavior, it is allowed to pass through12 Therefore, dynamic analysis is not always performed to determine if a file contains malware, as it depends on the results of the cache lookup and static analysis. Similarly, if the cache lookup determines that a file contains malware, static analysis is not performed to verify the results, as the file is already blocked based on the cache lookup12 References:

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?
- A. SIP ALG
- B. AppQoE
- C. AppFW
- D. AppQoS
Answer: D
Explanation:
Explanation
AppQoS is a service that allows you to prioritize and manage the quality of service (QoS) for different types of applications on SRX Series devices. AppQoS uses application signatures to identify and classify the traffic, and then applies QoS policies to assign bandwidth, priority, and scheduling parameters to the traffic. AppQoS can help you optimize the performance of critical applications, such as VoIP, and ensure that they get the required bandwidth and latency in a congested network12. In this scenario, you can use AppQoS to prioritize the VoIP traffic over other traffic and guarantee its QoS on the SRX Series device at the branch office. References:
