NEW QUESTION # 46
The UTM features are performed during which process of the SRX Series device's packet flow?
- A. screens
- B. zones
- C. security policies
- D. services
Answer: D
Explanation:
Comprehensive Detailed Step-by-Step Explanation with All Juniper Security Reference:
Understanding SRX Packet Flow:
The SRX Series device processes traffic in a specific sequence of operations, including zones, security policies, NAT, and services.
UTM (Unified Threat Management) features, such as antivirus, web filtering, and content filtering, are considered advanced services and are applied during the services processing stage.
Explanation of Each Option:
Option A: Services
UTM features are categorized under "services" because they involve advanced traffic inspection, filtering, and threat detection.
UTM services are triggered after basic security policies are applied and are performed as part of the packet processing workflow.
Correct.
Option B: Security Policies
Security policies are used to allow, deny, or permit traffic between zones.
Although policies determine whether traffic is allowed, UTM services are applied only after traffic matches a security policy that permits it.
UTM processing does not occur during the security policies stage.
Incorrect.
Option C: Zones
Zones define the logical segmentation of a network on SRX devices.
While zones determine traffic directionality and security boundaries, UTM features are not applied at this stage.
Incorrect.
Option D: Screens
Screens are used for DoS (Denial of Service) protection and detect specific types of malicious activity, such as SYN floods or port scans.
Screens focus on session-level protections, not UTM-specific traffic filtering or inspection.
Incorrect.
Where UTM Fits in the Packet Flow:
After a security policy permits traffic, advanced features such as UTM are applied in the services processing stage.
The typical SRX packet flow includes:
Ingress Interface
Zones and Screens
Security Policies
Services (UTM, IDP, etc.)
NAT (if applicable)
Egress Interface
Juniper Security Reference:
Refer to the Juniper SRX Packet Flow Documentation for more details on how UTM and services are integrated into the packet flow.
NEW QUESTION # 47
Your company is adding IP cameras to your facility to increase physical security. You are asked to help protect these loT devices from becoming zombies in a DDoS attack.
Which Juniper ATP feature should you configure to accomplish this task?
- A. IPsec
- B. allowlists
- C. static NAT
- D. C&C feeds
Answer: D
Explanation:
Juniper ATP should be configured with C&C feeds that contain lists of malicious domains and IP addresses in order to prevent IP cameras from becoming zombies in a DDoS attack.
This is an important step to ensure that the IP cameras are protected from malicious requests - and thus, they will not be able to be used in any DDoS attacks against the facility.
NEW QUESTION # 48
What is an IP addressing requirement for an IPsec VPN using main mode?
- A. Both peers must have static IP addressing.
- B. One peer must have dynamic IP addressing.
- C. One peer must have static IP addressing.
- D. Both peers must have dynamic IP addresses.
Answer: A
NEW QUESTION # 49
Which statement is correct about unified security policies on an SRX Series device?
- A. A global policy is always evaluated first.
- B. A zone-based policy is always evaluated first.
- C. The first policy rule is applied regardless of the policy level.
- D. The most restrictive policy is applied regardless of the policy level.
Answer: B
NEW QUESTION # 50
You want to generate reports from the l-Web on an SRX Series device.
Which logging mode would you use in this scenario?
- A. local
- B. Stream
- C. Event
- D. Syslog
Answer: B
NEW QUESTION # 51
What is the main purpose of using screens on an SRX Series device?
- A. to provide protection against common DoS attacks
- B. to provide multiple ports for accessing security zones
- C. to provide an alternative interface into the CLI
- D. to provide information about traffic patterns traversing the network
Answer: A
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.
