You have a Level 1－only router (Router A) in IS－IS area 49.0001.How does Router A learn how to reach prefixes in other areas?() A. Router A must have a Level 2 adjacency with the Level 1/Level 2 router in area 49.0001.B. The Level 1/Level 2 router in area 49.0001 sets the attached bit in the Level 2 LSP it floods into area 49.0001.C. The Level 1/Level 2 router in area 49.0001 sets the attached bit in the Level 1 link-state PDU (LSP) it floods into area 49.0001.D. The Level 1/Level 2 router in area 49.0001 advertises these prefixes into area 49.0001 using a Level 2 LSP it floods into the area.

Refer to the exhibit. Which two statements are true?() A. DHCPDISCOVER packets will reach the DHCP server.B.
