7 R z3 t3 C7 p% z& l( ?- K8 z; d6 lIt is impossible to do it as you don't know which tickets they will ask you on the exam. & q1 b" ?7 ~$ D% y. x& Y$ r4 R
So, you should ping and check each device in order to find the errors and solutions. Otherwise, you may choose the wrong answer and then it may affect next tickets . - lose marks and fail...

Some of my suggestions have been provided below:
; f: p# l; N j6 ^. u1st - you need to justify ipv4 question or ipv6 question
+ M. y1 E. l2 N1 D5 G' g: b2nd - for ipv4 question
3 J+ L- Y: V1 P, Rping 10.2.1.1 (DSW1) on client -> fail _> check DSW1 (vlan filter) and ASW1 (port security / access vlan / switch to switch trunk) & E1 U4 L" o2 Y7 e% x, c h5 ]5 E' n
if ping 10.2.1.1 -> ok, then ping 10.1.1.10 (R4) -> fail and then check R4 (eigrp passive interface and redistribution route-map ospf -> eigrp ) - \& f( `, l) H" i, X0 f& x
if ping 10.1.1.10, then ping 10.1.1.2 and 10.1.1.1 -> pass and then check R1 (BGP / NAT/ NAT ACL / R1 ACL) , normally , R1 (always asks bgp and NAT only) ' [ f+ d* u. k8 X! E3 ]& y3 Z
if ping 10.1.1.1 -> fail , then check R1 and problem should be ospf authentication (but this question should seldom be asked. )
