   In mixed mode, how does the Junos security platform handle traffic that arrives on a transparent interface and is destined for a host on a routed interface?

   • AThe traffic is routed at Layer 3 and then subject to security policy enforcement.
   • BThe traffic is encapsulated with a VLAN tag and forwarded to the routed interface.
   • CThe traffic is forwarded at Layer 2 to the routed interface without any policy checks.
   • DThe traffic is dropped because mixed mode does not allow traffic to pass between transparent and routed interfaces.

   An administrator is troubleshooting an SRX in mixed mode. A host on a transparent segment cannot reach a server on a routed segment. The administrator has verified the security policy permits the traffic and the host's default gateway is correct. Which command should the administrator use to check whether the SRX is forwarding the traffic to the correct next hop?

   • Ashow security policies
   • Bshow route 192.168.1.0/24
   • Cshow ethernet-switching table
   • Dshow interfaces terse

   An SRX in mixed mode is dropping traffic between a host on a transparent segment (VLAN 10) and a server on a routed segment (192.168.1.0/24). The administrator has verified the security policy is correct and the host's default gateway is the SRX's routed interface. The host can ping the SRX's routed interface IP, but cannot ping the server. What is the most likely cause?

   • AThe security policy is applied in the wrong direction
   • BThe SRX is not learning the MAC address of the host on VLAN 10
   • CThe server's default gateway is not set to the SRX's routed interface IP
   • DThe SRX is not running a routing protocol to learn the 192.168.1.0/24 route

   A company is deploying an SRX in mixed mode. The SRX has interface ge-0/0/0 that must be a trunk carrying VLANs 10 and 20 in transparent mode, and interface ge-0/0/1 that must be a routed interface. The administrator has configured family ethernet-switching and flexible VLAN tagging on ge-0/0/0. What is the next step to complete the transparent mode configuration?

   • AAssign IP addresses to the VLANs on ge-0/0/0
   • BConfigure a routing protocol on ge-0/0/0
   • CCreate Layer 2 security zones and bind the VLANs to the zones
   • DEnable STP on ge-0/0/0

   In Junos security platforms, what is the defining characteristic of mixed mode operation?

   • AInterfaces operate exclusively in routed mode, forwarding traffic at Layer 3 with routing decisions.
   • BInterfaces automatically switch between transparent and routed modes based on traffic load.
   • CSome interfaces operate in transparent mode while others operate in routed mode on the same device.
   • DInterfaces operate exclusively in transparent mode, forwarding traffic at Layer 2 without routing.
