• C.  PEI brings the SAP in VPWS 4 operationally down.

• A.  When PEI learns MAC-01, it advertises a MAC/IP route which indicates that MAC-OI is associated with ESI I.
• B.  PE3 advertises an A-D per ES route which indicates that ESI I is operating in a single-active redundancy mode.
• C.  PEI advertises an A-D per ES route which indicates that ESI 1 is operating in a single-active redundancy mode.
• D.  PEI advertises an A-D per EVI route which includes a P flag set to I to indicate that PEI is the DF for EVI 20.

Which of the following actions is performed by PEI after it receives a BUM packet from CEI?

• A.  PEI sends the packet to PE2 but not to PE3 because PE3 is connected to the originating ES.
• B.  PEI sends the packet to PE2 and to PE3. An ESI label is included only in the packet sent to PE2.
• C.  PEI sends the packet to PE2 and to PE3. An ESI label is included only in the packet sent to PE3.

• A.  MAC/IP routes, A-D per EVI routes, and A-D per ES routes
• B.  A-D per EVI routes, A-D per ES routes, and Ethernet segment (ES) routes
• C.  Auto-discovery per EVPN instance (A-D per EVI) routes and Auto-discovery per Ethernet segment (A-D per ES) routes only
• D.  A-D per EVI routes and ES routes only
