NEW QUESTION # 99
Refer to the table.
A customer investigates connectivity options for a DCI between two production data centers to aid a large- scale migration project. The solution must provide a single 10G connection between locations and be able to run its own varying QoS profiles without service provider interaction based on the migration stages. All connectivity methods are at 10 Gbps. Which transport technology costs the least if the connectivity is required for just one year?
Answer: D
Explanation:
-
Let's calculate total 1-year cost for each option using the provided table:
* DWDM over dark fiber:
* CAPEX = $250,000
* OPEX (1 year) = $100,000
* Installation fee = $30,000
* Total = $250,000 + $100,000 + $30,000 = $380,000
* CWDM over dark fiber:
* CAPEX = $150,000
* OPEX (1 year) = $100,000
* Installation fee = $25,000
* Total = $150,000 + $100,000 + $25,000 = $275,000
* MPLS wires only:
* CAPEX = $50,000
* OPEX (1 year) = $80,000
* Installation fee = $5,000
* Total = $50,000 + $80,000 + $5,000 = $135,000
* BUT: MPLS does not allow customer-controlled QoS policies as stated in the requirement (cannot run its own varying QoS profiles without SP interaction). Therefore disqualified.
* Metro Ethernet:
* CAPEX = $45,000
* OPEX (1 year) = $100,000
* Installation fee = $5,000
* Total = $45,000 + $100,000 + $5,000 = $150,000
* BUT: Metro Ethernet is also typically a service provider-managed solution where customer-controlled QoS is usually limited depending on SP capabilities. May not fully meet the requirement.
-
The key technical requirement:
"Be able to run its own varying QoS profiles without service provider interaction." This clearly favors dark fiber solutions (CWDM and DWDM), as these give full Layer 1 control to the customer, allowing complete freedom in managing QoS, traffic engineering, and prioritization internally.
Among the two dark fiber options, CWDM over dark fiber is the most cost-effective choice for one year at
$275,000.

Therefore, final correct answer:
NEW QUESTION # 100
Company XYZ has two routing domains (EIGRP and OSPF). They want full reachability and need OSPF to see link costs added to external routes. How must redistribution be designed?
Answer: C
Explanation:
* B (OSPF Type 1 external):Type 1 external routes include both the external cost (from redistribution) and the internal OSPF cost to the ASBR. This ensures accurate end-to-end metric calculation across domains.
Other options explained:
* A: Type 2 external ignores internal OSPF cost, potentially creating suboptimal routing.
* C/D: EIGRP doesn't use OSPF metric types; redistribution into EIGRP uses EIGRP metrics.
