A customer needs a design for a new data center network that meets these requirements:
• Logically partition the environment into separate security domains.
• Cut costs related to purchasing additional equipment.
• Separate routing processes, TCAM, QoS tables, and data planes.
Which technology must be used?
To logically partition the environment into separate security domains and cut costs related to purchasing additional equipment, while also considering separate routing processes, TCAM, QoS tables, and data planes, Virtual Device Context (VDC) is the appropriate technology. VDC allows the partitioning of a single physical switch into multiple logical devices, which aligns with the requirement for logically partitioning the environment into separate security domains and separating routing processes and data planes. Although TCAM is shared among VDCs, VDCs can still fulfill most of the requirements mentioned, making it the best choice among the options given.
Virtual Device Context (VDC) sounds like the closes solution.
The request is which technology must be used, however it doesn't mean that it will resolve all requirements, so with this clarification lets see the options: A. VLAN - it will not cut costs related to purchasing additional equipment, also it will not separate routing processes... B. vPC - it will not meet any requirement; C. VDC - the only requirement that it will not meet is the TCAM, however this technology must be used to attend most of requirements. So, C is the best option. D. VRF - it will not meet: TCAM, QoS table, and data planes
TCAM is shared between all VDCs. Thus if we follow this requirement, only vPC is correct. But that goes against the second requirement.
for item 3 "Separate routing processes, TCAM, QoS tables, and data planes." only vdc is correct
TCAM is shared between VDCs, so no, vdc isn't the correct option.
