Overview of the 640-816-Lab Interconnecting Cisco Networking Devices Exam
The 640-816-LAB certification validates technical proficiency for network engineers managing small-to-medium enterprise branch infrastructures. Candidates must demonstrate configuration and troubleshooting expertise regarding IPv4 addressing, VLSM, and static routing protocols alongside dynamic routing via RIPv2, OSPF, and EIGRP. Practical assessment requires implementation of Layer 2 technologies including VLANs, VTP, STP, and inter-VLAN routing on Catalyst switches. Security objectives necessitate the deployment of standard and extended access control lists, while WAN connectivity focuses on HDLC, PPP, and Frame Relay encapsulations. Competency in NAT, PAT, and DHCP services is critical for addressing, while IOS management involves secure remote access and password recovery procedures.
