                          質問 # 18
                          Which two statements are true about the NextGen Web Filtering (NGWF) feature on an SRX Series device? (Choose two.)

                          正解:A、D

                          解説:
                          NextGen Web Filtering consults the Juniper cloud first to categorize and evaluate URLs in real time, ensuring up-to-date threat and content intelligence.
                          NextGen Web Filtering is a licensed feature and requires a valid subscription to operate on an SRX Series device.


                          質問 # 19
                          Which statement is correct about exception traffic?

                          正解:B

                          解説:
                          Exception traffic refers to traffic that must be sent from the Packet Forwarding Engine (PFE) to the Routing Engine (RE) for processing, such as routing protocol updates, management traffic, and control-plane destined packets.
                          Option B: Correct. Exception traffic is rate-limited on the internal connection between the PFE and RE to protect the Routing Engine from denial-of-service attacks.
                          Option A: Incorrect. Exception traffic is not handled only on the PFE; it requires RE involvement.
                          Option C: Incorrect. Rejected traffic by security policies is simply dropped, not classified as exception traffic.
                          Option D: Incorrect. Malformed packets are dropped, not considered exception traffic.
                          Correct Statement: Exception traffic is rate-limited between the PFE and RE.


                          質問 # 20
                          You want to verify the effectiveness of Web filtering on the SRX Series Firewall.
                          How would you accomplish this task?

                          正解:B

                          解説:
                          The simplest and most direct method of verifying Web filtering effectiveness isto attempt to access permitted and blocked URLs.
                          * Option A:Installing a local NGWF server is not required; NGWF queries Juniper's cloud.
                          * Option B:File extension checking applies to content filtering, not web filtering.
                          * Option C:Examining policies shows configuration but does not verify enforcement.
                          * Option D:Correct. Attempting to browse URLs that should be blocked or allowed confirms the Web filtering policy is effective.
                          Correct Method:Attempt to access permitted or blocked URLs
                          Reference:Juniper Networks -Verifying Web Filtering Configuration, Junos OS Security Fundamentals.


                          質問 # 21
                          You are asked to create a security policy that controls traffic allowed to pass between the Internet and private security zones. You must ensure that this policy is evaluated before all other policy types on your SRX Series device.
                          In this scenario, which type of security policy should you create?

                          正解:C

                          解説:
                          * Global policies (Option D):Evaluated before zone-based policies. They allow centralized control and can apply across all zones. Perfect for Internet-to-private traffic that must be enforced before other rules.
                          * Routing policy (Option A):Controls routing decisions, not traffic forwarding/security.
                          * Default policy (Option B):Denies all traffic by default, but cannot be customized for early evaluation.
                          * Zone policy (Option C):Zone-based policies apply after global policies and are limited to specific zone pairs.
                          Correct Policy Type:Global policy
                          Reference:Juniper Networks -Global Security Policies vs Zone-Based Policies, Junos OS Security Fundamentals.


                          質問 # 22
                          Which two statements about the host-inbound-traffic parameter in a zone configuration are correct? (Choose two.)

                          正解:B、C

                          解説:
                          SSH Access (Option B): Host-inbound-traffic controls traffic destined to the SRX device itself (management/control plane). If host-inbound-traffic is not configured to allow SSH, then SSH access to the firewall is blocked.
                          Explicit Zone Configuration (Option D): For user-defined security zones, host-inbound-traffic must be explicitly configured to allow specific services (SSH, ICMP, SNMP, etc.).
                          Console Access (Option A): Console access is not controlled by host-inbound-traffic. Console access is always available directly.
                          Management Zone (Option C): In the management functional zone, host-inbound-traffic is implicitly allowed for management services, so this is not explicitly required.
                          Correct Statements: B and D
