GNS As Network Interview Tool - Test 1 (Layer-2)
Recently I was interviewing lots of people for a Level-2 Engineer profile. The requirement was for one of my Enterprise client NOC. The client simply asked me to ensure only quality Engineers get through this. So I decided to change my regular interview pattern this time. I designed a Series of hands on test for this purpose. So here is the Test-1. Though I wrote this for level-2 Engineers to ensure even a rusty CCNP Engineer can qualify this but even I expect a Good CCNA Engineer to pass this easily.
üAll VLANs are
üAll passwords are
database using “ sh vlan-switch brief
any local user account.
default console settings.
username “abc” for ssh testing.
üThere are some configuration
faults which you may need to find and fix.
üDon’t reload the
device without checking with Interviewer.
üThe given time for
test is 35 Mins.
Ø1. Configure all
inter switch links as 802.1Q Trunks.
Ø2. Make sure SW-1
is Root Bridge for VLAN 10 , SW-2 is Root Bridge for VLAN 20 , SW-3 is Root
Bridge for VLAN 30
Ø3. Configure the inter switch links between R1 & R2
, R1 & R3 so that none of the link is in spanning tree block state.
Ø4. Make sure all
switches are able to telnet each other. Use password as " cisco "
whenever required. Management IPs are as Followed:
SW-1 > 220.127.116.11/24
SW-2 > 18.104.22.168/24
SW-3 > 22.214.171.124/24
Ø5. Configure SW-1
so that it allows SSH connection for management in INBOUND direction. Make sure
when you SSH from SW-2/SW-3, you are able to get SSH login Prompt.
Ø6. Enable SNMP
environmental monitor traps on SW-2 to ensure traps are generated for High
Temperature & Fan failures for example. The traps should be sent out to NMS
Address “126.96.36.199”. Use community value as “ cisco “ if required.
Ø 7. Create a SPAN
(AKA Port Mirroring) session with source interface as Fa1/5 on SW3. The SPAN
Destination is Fa1/6
