Question Image

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 You can secure inter-VLAN traffic with a security policy on this device.
  • C The device can pass Layer 2 and Layer 3 traffic at the same time.
  • D The device cannot pass Layer 2 and Layer 3 traffic at the same time.
Explanation

An SRX can use mixed transparent and route mode, with Layer 2 and Layer 3 interfaces configured in separate security zones on the same device. This permits concurrent Layer 2 bridging and Layer 3 routing, and security policies can secure inter-VLAN traffic handled by the routed interfaces. Transparent-mode policies apply between Layer 2 security zones, rather than to traffic switched within the same VLAN.
