Exhibit:
Referring to the exhibit, which two statements are correct? (Choose two.)
A. You cannot secure intra-VLAN traffic with a security policy on this device.
B. The device cannot pass Layer 2 and Layer 3 traffic at the same time.
C. You can secure inter-VLAN traffic with a security policy on this device.
D. The device can pass Layer 2 and Layer 3 traffic at the same time.
正解：C、D
解説：
The exhibit provides information about an SRX Series device operating intransparent mode(Layer 2) and Layer 3routing at the same time. Let's break down the correct answers:
* Explanation of Answer B (Secure Inter-VLAN Traffic with a Security Policy):
* The SRX device can secureinter-VLAN trafficbecause it supports security policies for Layer 3 traffic between different VLANs. In this case, traffic moving between different VLANs (i.e., Layer 3 traffic) can be processed and controlled using security policies.
* Explanation of Answer C (Pass Layer 2 and Layer 3 Traffic Simultaneously):
* The SRX device can handle both Layer 2 and Layer 3 traffic simultaneously. Inmixed mode, the device is capable of switching traffic at Layer 2 (intra-VLAN) while also routing traffic at Layer
3 (inter-VLAN). This is evident from the global configuration showingtransparent bridge mode and Layer 3 interfaces.
Juniper Security Reference:
* Mixed Mode Overview: Juniper SRX devices in mixed mode can operate as both a Layer 2 switch and a Layer 3 router, allowing it to pass traffic at both layers simultaneously. Reference: Juniper Mixed Mode Documentation.
質問 # 70
Exhibit:
Referring to the exhibit, which two statements are true? (Choose two.)
A. Hosts in the Local zone can be enabled for control plane access to the SRX.
B. Hosts in the Local zone can communicate with hosts in the Trust zone with a security policy.
C. You can configure security policies for traffic flows between hosts in the Local zone.
D. An IRB interface is required to enable communication between the Trust and the Untrust zones.
正解：A、B
質問 # 71
Which two statements are true about the procedures the Junos security device uses when handling traffic destined for the device itself? (Choose two.)
A. If the received packet is addressed to the ingress interface, then the device first performs a security policy evaluation for the junos-host zone.
B. If the received packet is destined for an interface other than the ingress interface, then the device performs a security policy evaluation for the junos-host zone.
C. If the received packet is destined for an interface other than the ingress interface, then the device performs a security policy evaluation based on the ingress and egress zone.
D. If the received packet is addressed to the ingress interface, then the device first examines the host- inbound-traffic configuration for the ingress interface and zone.
正解：B、D
解説：
When handling traffic that is destined for itself, the SRX examines the host-inbound-traffic configuration for the ingress interface and the associated security zone. It evaluates whether the traffic should be allowed based on this configuration. Traffic not addressed to the ingress interface is handled based on security policies within the junos-host zone, which applies to traffic directed to the SRX itself. For more details, refer to Juniper Host Inbound Traffic Documentation.
When handling traffic that is destined for the SRX device itself (also known as host-bound traffic), the SRX follows a specific process to evaluate the traffic and apply the appropriate security policies. The junos-host zone is a special security zone used for managing traffic destined for the device itself, such as management traffic (SSH, SNMP, etc.).
* Explanation of Answer B (Packet to a Different Interface):
* If the packet is destined for an interface other than the ingress interface, the SRX performs a security policy evaluation specifically for the junos-host zone. This ensures that management or host-bound traffic is evaluated according to the security policies defined for that zone.
* Explanation of Answer C (Packet to the Ingress Interface):
* If the packet is addressed to the ingress interface, the device first checks the host-inbound- traffic configuration for the ingress interface and zone. This configuration determines whether certain types of traffic (such as SSH, HTTP, etc.) are allowed to reach the device on that specific interface.
Step-by-Step Handling of Host-Bound Traffic:
* Host-Inbound Traffic: Define which services are allowed to the SRX device itself:
bash
set security zones security-zone <zone-name> host-inbound-traffic system-services ssh
* Security Policy for junos-host: Ensure policies are defined for managing traffic destined for the SRX device:
bash
set security policies from-zone <zone-name> to-zone junos-host policy allow-ssh match source-address any set security policies from-zone <zone-name> to-zone junos-host policy allow-ssh match destination-address any Juniper Security Reference:
* Junos-Host Zone: This special zone handles traffic destined for the SRX device, including management traffic. Security policies must be configured to allow this traffic. Reference: Juniper Networks Host-Inbound Traffic Documentation.

Which two statements describe the behavior of logical systems? (Choose two.)
A. A default routing instance is automatically created for each logical system.
B. Each logical system has a copy of the routing protocol process.
C. Each logical system shares the routing protocol process.
D. A default routing instance must be manually created for each logical system
正解：A、B
