Note: I haven’t had enough information to answer these questions, but below are answers and explanations from candidates who took the exam and shared their experience (thanks Sanjana Chopra & DBurger for sharing this).
Command used to answer this question: show ip ospf database
By using this command you will get the Router ID
An example of the output of this command is shown below:
Router#show ip ospf database
OSPF Router with ID (192.168.2.2) (Process ID 1)
Router Link States (Area 0)
| Link ID | ADV Router | Age | Seq# | Checksum | Link count |
| 192.168.1.1 | 192.168.1.1 | 141 | 0×80000002 | 0x00fca8 | 1 |
| 192.168.2.2 | 192.168.2.2 | 57 | 0×80000002 | 0x00fe9f | 1 |
| 192.168.2.1 | 192.168.2.1 | 57 | 0×80000006 | 0x00a212 | 2 |
Net Link States (Area 0)
| Link ID | ADV Router | Age | Seq# | Checksum |
| 192.168.1.2 | 192.168.2.1 | 141 | 0×80000001 | 0×006218 |
| 192.168.2.2 | 192.168.2.2 | 57 | 0×80000001 | 0×006016 |
In this case the Router ID is 192.168.2.2
Fourth question is about ipv6 eigrp. Over the same lan segment, shows loopback interfaces running eigrpV3, everything n is ok and pings don’t work. The right option is that u have to configure eigrp process on each router (doing it in only one is not enough) This is true because Eigrpv6 needs a no shut under the process to work!
Third question is about QOS. Shows u some markings by packet lenght. Options are that the firrst class is marking packets which size is between 500 and 1500 bytes, which is RIGHT. Second option is that second class is marking packets with size of 500 with ip precendence 3 which is not wrong, because altouhg one of the condifions is lenght= 500, thsa class statement is a MATCH ALL and there is also another condition regardiong DSCP, so paket lengh is not enough for marlking here. This option is WRONG. Third option is that one of the clases is marking packets with size = 200 and this is true.
Second question is about IPV6 multicast.( Over the lan link between two routers) Shows you Mroute entry and gives several options. Right answers are that the multicast group in the shared tree is FFF0:0002 (or whatever I dont remember but u should check it on the (*. XXXX)
and the second answer is that a route to the RP has been pruned, which can be confirmed by checking the flags SPC (sparse mode, connected, pruned)
Command used to answer this question: show ipv6 mroute
