Cisco Certified Design Expert (CCDE v3.0)
A: typically used over long distances, but requires optical amplification
B: uses the 850nm band
C: allows up to 32 optical earners to be multiplexed onto a single fiber
D: shares the same transmission window as DWDM
E: Passive CWDM devices require no electrical power
A: MPLS TE replaces LDP and the dependency of the IGP to identify the best path.
B: MPLS TE provides link and node protection
C: MPLS TE optimizes the routing of IP traffic, given the constraints imposed by backbone capacity and application requirements.
D: MPLS TE requires Layer 3 VPN full-mesh topology deployment
A: PortFast does not generate a spanning tree topology change hen a station on a port is connected or disconnected
B: PortFast disables spanning tree on the port, which puts the port into the forwarding state immediately after it is connected
C: PortFast allows small, unmanaged switches to be plugged into ports of access switches without risking switch loops
D: PortFast detects one-way communications on the physical port, which prevents switch loops
E: PortFast prevents switch loops that are caused by a unidirectional point to point link condition on Rapid PVST+ and MST
F: PortFast prevents switched traffic from traversing suboptimal paths on the network
A: redundant design
B: modular design
C: less complex design
D: routed access design
