What is the type that is an integer greater than or equal to 1522?

• A. SWVC End Point Map
• B. SD-WAN UNI Maximum L2 Frame size
• C. Cantata
• D. Legato

Answer: (B)

The key idea is the maximum L2 frame size at the SD-WAN UNI. Ethernet frames have a size limit, and when VLAN tagging is used, the maximum frame size becomes 1522 bytes (1518 bytes for the untagged framePlus 4 bytes for the VLAN tag). In MEF SD-WAN terms, the parameter that is defined as an integer representing this limit at the UNI is the SD-WAN UNI Maximum L2 Frame size. Since 1522 (or larger) is the typical bound for VLAN-tagged Ethernet frames, this is the type that fits the description. The other terms refer to different concepts (endpoint mapping or other vendor terms) and do not describe the frame-size limit.
