Exam Description
|
 |
|
|
BCMSN is a qualifying exam for the Cisco Certified Network
Professional CCNP® as well as the Cisco Certified Design
Professional CCDP® certifications. The BCMSN exam (642-811)
will test materials covered under the new Building Cisco
Multilayer Switched Networks (BCMSN) CCNP course. The exam
will certify that the successful candidate has important
knowledge and skills necessary to build scalable multilayer
switched networks; create and deploy a global intranet, and
implement basic troubleshooting techniques in environments
that use Cisco multilayer switches for client hosts and
services. The exam covers topics on switching technology,
implementation and operation, planning and design, and
troubleshooting.
