Suggestions for interview questions

[Daniel Siemens]

Q.	What is the decimal notation of subnet mask of 255.255.255.0

A.	/24

 

Q.	What type of DNS record is associated with email servers

a.    MX /Mail Exchanger  and Reverse DNS   (99% will miss Reverse DNS
unless they have ran their own mail server)

 

Q.  If I build a Ipsec vpn from Site 1 to Site 2 to Site 3, Can I ping a
host on site 3 from site 1.   

A. No.   Ipsec creates rules to join networks.   Generally you can't
route traffic between tunnels.   

 

Q.   Most managed switchs us a technique called spanning tree.   A lot
of embedded devices will miss DHCP when because their boot up time is so
fast that the port is not alive before the switch determines that you do
not have a loop back condition.   What is the correct way to solve this.

A.   In some switches they have a feature called port fast, turn this on
ports that have embedded devices.   In some middle ground switches you
have to disable spanning tree on that port or even the complete switch.

 

 

That's a few.   They might be a bit beyond any junior person but if you
want someone that really knows their stuff I would get a bit harder than
these.

Subject: Suggestions for interview questions

 

What type of networking questions would you suggest to weed out
interview candidates during a 15 minute phone conversation? The emphasis
would not be on any particular platform, but rather to discover if the
candidate had a general understanding of tcpip networking, hardware,
infrastructure, security, nat, firewalls, vpns, ipsec, ssl, dns, hubs,
switches, routers, etc.

Example: 

Q: Can you name a protocol responsible for dynamic IP address
assignment? 
A: BOOTP or DHCP
