Question #2
What are two Juniper ATP Cloud feed analysis components? (Choose two.)
- A . IDP signature feed
- B . C&C cloud feed
- C . infected host cloud feed
- D . US CERT threat feed
Correct Answer: A,B
A,B
Explanation:
The Juniper ATP Cloud feed analysis components are the IDP signature feed and the C&C cloud feed. The IDP signature feed provides a database of signatures from known malicious traffic, while the C&C cloud feed provides the IP addresses of known command and control servers. The infected host cloud feed and US CERT threat feed are not components of the Juniper ATP Cloud feed analysis.
To learn more about the Juniper ATP Cloud feed analysis components, refer to the Juniper Networks Security Automation and Orchestration (SAO) official documentation, which can be found at https://www.juniper.net/documentation/en_US/sao/topics/concept/security-automation-and-orchestration-overview.html. The documentation provides an overview of the SAO platform and an in-depth look at the various components of the Juniper ATP Cloud feed analysis.

- B . advanced security policy
- C . antispam feature-profile
- D . antispam UTM policy
Correct Answer: B
Question #5
Which statement is correct about Web filtering?
- A . The Juniper Enhanced Web Filtering solution requires a locally managed server.
- B . The decision to permit or deny is based on the body content of an HTTP packet.
- C . The decision to permit or deny is based on the category to which a URL belongs.
- D . The client can receive an e-mail notification when traffic is blocked.
Correct Answer: C
C
Explanation:
Web filtering is a feature that allows administrators to control access to websites by categorizing URLs into different categories such as gambling, social networking, or adult content. The decision to permit or deny access to a website is based on the category to which a URL belongs. This is done by comparing the URL against a database of categorized websites and making a decision based on the policy defined by the administrator.

Question #6
An application firewall processes the first packet in a session for which the application has not yet been identified.
In this scenario, which action does the application firewall take on the packet?
- A . It allows the first packet.
- B . It denies the first packet and sends an error message to the user.
- C . It denies the first packet.
- D . It holds the first packet until the application is identified.
Correct Answer: D
D
Explanation:
This is necessary to ensure that the application firewall can properly identify the application and the correct security policies can be applied before allowing any traffic to pass through.
If the first packet was allowed to pass without first being identified, then the application firewall would not know which security policies to apply – and this could potentially lead to security vulnerabilities or breaches. So it’s important that the first packet is held until the application is identified.

Question #7
What are two functions of Juniper ATP Cloud? (Choose two.)
- A . malware inspection
- B . Web content filtering
- C . DDoS protection
- D . Geo IP feeds
Correct Answer: A,D
A,D
Explanation:
Juniper Advanced Threat Prevention (ATP) Cloud is a security service that helps organizations protect against advanced threats by providing real-time threat intelligence and automated response capabilities. It combines a cloud-based threat intelligence platform with the security capabilities of Juniper Networks security devices to provide comprehensive protection against advanced threats. The two functions of Juniper ATP Cloud include malware inspection and Geo IP feeds. The malware inspection component provides real-time protection against known and unknown threats by analyzing suspicious files and determining if they are malicious. The Geo IP feeds provide a global view of IP addresses and their associated countries, allowing organizations to identify and block traffic from known malicious countries.

Question #8
What is the main purpose of using screens on an SRX Series device?
- A . to provide multiple ports for accessing security zones
- B . to provide an alternative interface into the CLI
- C . to provide protection against common DoS attacks
- D . to provide information about traffic patterns traversing the network
Correct Answer: C
C
Explanation:
The main purpose of using screens on an SRX Series device is to provide protection against common Denial of Service (DoS) attacks. Screens help prevent network resources from being exhausted or unavailable by filtering or blocking network traffic based on predefined rules. The screens are implemented as part of the firewall function on the SRX Series device, and they help protect against various types of DoS attacks, such as TCP SYN floods, ICMP floods, and UDP floods.
