Hello. In general, how are the roles/responsibilities distinguished between a network engineer/administrator with a CCNA certification and a network engineer/administrator with a CCNP certification? Given that CCNP has specialties, let's assume the CCNP certified administrator earned their CCNP R&S. Thanks.
CCNA Responsibilities Vs. CCNP Responsibilities
There's a couple of different answers and they depend on context!
So, for example in a small company, there may not be any real differences of responsibilities between the CCNA and CCNP. Heck for that fact between Support Desk and Network Infrastructure...You're the "IT Guy". So you may do it all regardless of your certification specialization.
In a large company with well defined Service Management, you may be very limited in your responsibilities. This doesn't mean less responsible but just more specialized and you'll have to perform maybe on an SLA basis...not only structured but interrupt support as well. Let me give you a couple of examples:
- As a CCNA, you may be managing lets say the branch office and field installation and maintenance and working with a department to support switch and routing do troubleshooting as well. This may be where you're responsible for cabling, basic configuration and R&R (Remove & Replace) on equipment and escalating.
- At the CCNP, you may be responsible for troubleshooting what the CCNA is not ready to do but also configuration and optimal routing and network performance. Once again you're goals will be set maybe based on where you work and what needs to be done.
*If we assumed you're a CCNP R+S, you could be hired for your a particular situation like migrating a network routing from EIGRP to OSPF or a rollover to IPv6 in a scheduled time. This would be more contract work and you'll have an SLA. It could be that you'll be providing support services maintaining infrastructure etc.
Many times the difference between the CCNA and CCNP level of knowledge has to do with the WHAT, HOW and WHY. The CCNA knows what to do and HOW to get it done. The CCNP know WHAT, HOW and WHY. The why becomes important is as devices multiple and systems become complex.
