Which interface types are assigned to IEEE 802.1Q VLANs?
IEEE 802.1Q is a networking standard that supports virtual LANs (VLANs) on an Ethernet network. It allows multiple VLANs to be configured on a single physical interface. In the context of network configurations, VLANs are typically assigned to Layer 2 subinterfaces. These are logical interfaces created under a physical interface for the purpose of VLAN tagging, which is essential for network segmentation and management. Layer 2 subinterfaces provide the capability to isolate and manage data traffic more effectively by assigning different VLAN IDs to different subinterfaces.
B IEEE 802.1Q is a standard for VLAN tagging in Ethernet networks. In Cisco IOS, VLANs are typically assigned to Layer 2 subinterfaces, which are logical interfaces that allow a physical interface to be divided into multiple virtual interfaces. Each Layer 2 subinterface can be assigned a unique VLAN ID, allowing traffic to be separated and managed based on VLAN membership.
According to https://docs.paloaltonetworks.com/pan-os/9-1/pan-os-web-interface-help/network/network-interfaces Both B and C are possibilities, but my CCNA kneejerk reaction would choose B. However, since you can do it at layer 3 (for the same money, "everything" layer 3 was more expensive in the past) and layer 2 is more vulnerable... . TBH this question should have a "choose two" option because neither can be excluded definetively.
Forget to add layer 3 would be the more "modern" option ...
I think it's B. Checked on the FW right now. The question says ASSIGNED so when you Add a Layer 2 Subinterface, there is an option at the bottom "Assign Interface to" and have a VLAN field. In a Layer 3 Subinterface doesn't.

Answer is B
Accordently "https://docs.paloaltonetworks.com/pan-os/11-0/pan-os-web-interface-help/network/network-interfaces/layer-3-subinterface#id5604fdd4-bce9-430d-a111-52372ecc194b" Correct Answer is C. You can create a Layer 3 subinterface for a PPPoE client for IEEE 802.1Q VLAN
Layer 2 does not have sub interfaces. Also 802.1Q is how you configure vlan in Layer 3 sub interface
I think letter C is the correct answer. See below. https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClRkCAK
How do u say that?
I think it is L3 subinterfaces. You can assign VLAN tag to VLAN interface. Subinterfaces in terms of Palo alto are only L3 subinterfaces.
B. https://docs.paloaltonetworks.com/pan-os/11-0/pan-os-web-interface-help/network/network-vlans
The answer is 'B'
