Click the Exhibit button. Referring to the exhibit, which statement is true?
A.
Only frames that do not have any VLAN tags are accepted.
B.
Packets sent tom the SRX Series device are sent to the RE.
C.
Packets sent to the SRX Series device are discarded.
D.
Only frames that have a VLAN ID of 20 are accepted.
This question is so delusive .
While D is correct , but in the “show security flow bridge” there is no “set no-packet-flooding” configured , so ARP\ICMP packets will pass .
Its A and C(if two are needed)……..because for traffic destined to the SRX we need an IRB interface for must…..Thus C…..
And since interfaces are access mode thus they expect untagged frames…..
But mostly A because other packets may still be able to pass the SRX like BPDUs etc…
please I need final answer here , any help
the answer is A

D correct thou ,
Its fantastic but:
When an untagged or tagged packet is received on an access interface, the packet is accepted, the VLAN ID is added to the packet, and the packet is forwarded within the bridge domain that is configured with the matching VLAN ID.
C correct then.
access—Configure a logical interface to accept untagged packets. Specify the VLAN to which this interface belongs using the vlan-id statement.
So, the right Answer is A…. “Only frames that do not have any VLAN tags are accepted.”
Because the ports are in Interface Mode Access.
