In R4.1 of the 15454, the ML-series Ethernet cards provide QoS enhancements that allow Service Providers to deliver CIR/PIR (Committed Information Rate/Peak Information Rate) type SLA’s. Which two specific QoS mechanisms were added to accomplish this?

The diagram shows a campus with a L2 switched backbone. The backbone has a single VLAN (= subnet) with no loops. The links into the backbone are routed interfaces, not VLAN trunks. Switch X is the STP root of the core VLAN and switch Y is the standby root. The connection between X and Y is an EtherChannel. The network architect wants to add more redundancy by connecting the L3 switches in the distribution layer to both X and Y. What best describes that plan?

When discussing FCIP compression what should be addressed?

What is the difference in power at the input and the output of the device under test?

What is the frequency of an optical signal with a wavelength of 1530 nm?
