The implementations group has been using the test bed to do a ‘proof-of-concept’ that requires
both Client 1 and Client 2 to access the WEB Server at 209.65.200.241. After several changes to the
network addressing, routing scheme, DHCP services, NTP services, layer 2 connectivity, FHRP
services, and device security, a trouble ticket has been opened indicating that Client 1 cannot ping
the 209.65.200.241 address.
Use the supported commands to isolated the cause of this fault and answer the following questions.
On which device is the fault condition located?
A.
R1
B.
R2
C.
R3
D.
R4
E.
DSW1
F.
DSW2
G.
ASW1
H.
ASW2
Explanation:
On R1, for IPV4 authentication of OSPF the command is missing and required to configure—— ip
ospf authentication message-digest
the scenario description is REALLY the same in so many tickets.
THAT way You cannot cheat and just “know” the answer.
you need to trouble shoot (at least a little) to determine which you are looking at.
Note: read the situation first:
if it is ipv6 loopback of Dsw1 -> ipv6 Loopback of R1 then that is one of THREE specific tickets.
If it is HSRP ….duh: only one possible
if it is the client1->webserver…that’s a number of possible tickets,
errDisable/ f’d up vACL+vLAN filter / Int swit allow vlan 10 / swit Trunk allow vlan 10
/ DHCP exclude or DHCP Range / Eigrp-OSPF redis (at R4) / NAT issue (at R1) / BGP neighbor or the external acl for Edge_security keeping BGP from establishing.
TRACE ROUTE DOES NOT WORK…..this killed me when I tried it and it didn’t do anything my heart sank immediately.
ping from R1 in and from Client 1 out…..that, IPCONFIG and “show ip route” or show ip ospf/eigrp/Ripng are just about all you have to work with.
MEMORIZE THE R1 / R2 / R3 / R4 Ip and IPv6 addresses…you CANNOT page back and forth fast enough to do this at the pace you will need to in order to pass.
THE TICKETS ARE NO LONGER ALLOWING you to “abort” and go BACK…you cannot finish ticket 13 before tackling tickets 2,3 & 4…you HAVE TO DO them in the order they are given and hit “NEXT” with no possible way to return back to them.
It’s not THAT hard an exam if you prep correctly.
