Which two features are included with UTM on an SRX Series device? (Choose two.)
- A. content filtering
- B. antivirus
- C. NAT
- D. IDP
正解：A、B
解説：
Comprehensive Detailed Step-by-Step Explanation with All Juniper Security Reference:
Understanding UTM (Unified Threat Management) Features on SRX Devices:
UTM is a security framework available on Juniper SRX Series devices that integrates multiple security features to protect against various threats. UTM functionalities are focused on advanced traffic inspection, content management, and threat prevention.
Explanation of Each Option:
Option A: Antivirus
UTM on SRX Series devices includes an antivirus feature that scans traffic for malware and viruses.
This feature is implemented using either:
Sophos Antivirus: A cloud-based solution.
Kaspersky Antivirus: A local database-based solution.
The antivirus feature detects and blocks malicious files, providing robust malware protection.
Correct.
Option B: NAT
Network Address Translation (NAT) is a fundamental networking feature on SRX devices but is not part of the UTM suite.
NAT is used to translate private IP addresses to public IP addresses and does not provide traffic filtering or threat management.
Incorrect.
Option C: IDP (Intrusion Detection and Prevention)
IDP is a separate feature on SRX devices for detecting and mitigating intrusions, but it is not part of the UTM framework.
IDP focuses on identifying malicious traffic patterns and blocking threats at the network level, whereas UTM focuses on content inspection and filtering.
Incorrect.
Option D: Content Filtering
Content filtering is a key UTM feature that blocks or allows traffic based on URL categories, keywords, and custom filtering rules.
This feature is used to restrict access to inappropriate or harmful websites and manage user behavior.
Correct.
UTM Features on SRX Devices Include:
Antivirus: Scans and blocks malware in real time.
Content Filtering: Manages access to websites and controls internet usage.
Web Filtering: Enforces policies on web content based on URL categories.
Spam Filtering: Blocks spam emails.
Juniper Security Reference:
Refer to the Juniper UTM Documentation for detailed configuration and feature details.
質問 # 62
Which two statements are correct about IPsec security associations? (Choose two.)
- A. IPsec security associations are unidirectional.
- B. IPsec security associations are established during IKE Phase 1 negotiations.
- C. IPsec security associations are bidirectional.
- D. IPsec security associations are established during IKE Phase 2 negotiations.
正解：C、D
解説：
The two statements that are correct about IPsec security associations are that they are bidirectional and that they are established during IKE Phase 2 negotiations. IPsec security associations are bidirectional, meaning that they provide security for both incoming and outgoing traffic. IPsec security associations are established during IKE Phase 2 negotiations, which negotiates the security parameters and establishes the security association between the two peers. For more information, please refer to the Juniper Networks IPsec VPN Configuration Guide, which can be found on Juniper's website.
