4A0-C03: Nokia NRS II Composite Exam: IS-IS version

On SR OS, a dot1q/QinQ SAP is defined as port:qtag1.qtag2, where a wildcard is permitted for the inner qtag when the outer qtag is explicit, but the outer qtag cannot be wildcarded while the inner tag stays explicit, and a single SAP definition cannot enumerate multiple discrete outer-tag values as alternatives. To accept only frames with outer VLAN 200 combined with inner VLAN 33, and separately outer VLAN 250 combined with inner VLAN 33, two SAPs must be configured — one per outer/inner tag pair — since no single wildcarded SAP expression matches exactly those two combinations without also matching unwanted traffic or missing one of the required outer tags.
