質問 # 98
Which two statements are correct about a Juniper Packet Forwarding Engine? (Choose two.)
正解：A、D
解説：
The Packet Forwarding Engine is the forwarding-plane component responsible for high-speed packet handling. Juniper documentation states that the PFE performs Layer 2 and Layer 3 packet switching, route lookups, and packet forwarding. This makes option A correct because transit traffic is forwarded by the PFE rather than by the control plane. The Routing Engine manages and programs the PFE by building routing information and copying the forwarding table to the PFE, making option B correct. Option C reverses the relationship and is therefore incorrect. Option D is also incorrect because routing tables are created and maintained by the Routing Engine and routing protocol processes; the resulting forwarding information is then installed into the PFE for packet forwarding.
質問 # 99
Referring to the exhibit, the top table shows the source and destination IP addresses and also the source and destination ports of the incoming packet. The lower table represents the security policies from the trust zone to the untrust zone.
In this scenario, which two statements are correct? (Choose two.)
正解：B、C
解説：
The packet's destination port is 80 (HTTP), which does not match any specific application policy in the table. As a result, it proceeds to the final policy, which denies all unmatched traffic (any any any deny).
Junos SRX evaluates security policies sequentially from top to bottom until a match is found.
Since no earlier policy matches HTTP traffic, the firewall enforces the final deny rule.
質問 # 100
You want to verify that your NextGen Web Filtering (NGWF) feature is connected to the Juniper cloud.
Which operational mode command would you use for this task?
正解：D
解説：
The show security web filtering status command displays the connection status between the SRX device's NextGen Web Filtering (NGWF) feature and the Juniper Cloud. It verifies that the SRX is properly communicating with the cloud service for URL categorization and policy enforcement.
質問 # 101
You are not able to ping an interface on an SRX Series Firewall.
Which two actions should you take to solve this issue? (Choose two.)
正解：A、B
解説：
For an SRX firewall interface to respond to management traffic such as ICMP pings:
* Theinterface must be assigned to a security zone(Option A). If an interface is not part of any zone, it is placed into the null zone, which drops all traffic.
* Additionally, the zone must be configured to allow management traffic types ashost-inbound-traffic (Option D). For ICMP, the protocol must be explicitly allowed under host-inbound-traffic for that zone.
Other options:
* Security policies (Option B) control traffic traversing the firewall, not traffic destined to the SRX device itself.
* Assigning the interface to the null zone (Option C) prevents any communication, including management.
Correct Actions:Assign the interface to a zone and configure ICMP under host-inbound-traffic.

質問 # 102
Which two statements are correct about security zones on an SRX Series device? (Choose two.)
正解：C、D
解説：
* Routing instances:Security zones are local to their routing instance. Theycannot be shared between routing instances(Option B is correct). Each routing instance must define its own zones.
* Intrazone and interzone traffic:Both types of traffic require policies in Junos OS. Intrazone traffic must have an explicit intra-zone policy to be controlled (Option C is correct).
* Sharing zones:Option A is incorrect, as zones cannot span routing instances.
* Multiple zones:SRX devices fully support multiple security zones (trust, untrust, DMZ, etc.). Option D is incorrect.
Correct Statements:B and C
