Answer: A,C


NEW QUESTION # 84
Retef to the exhibit.

An engineer is designing a multiarea OSPF network for a client who also has a large EIGRP domain. EIGRP routes are getting redistributed into OSPF. OSPF area 20 has routers with limited memory and CPU resources.
The engineer wants to block routes from EIGRP 111 from propagating into area 20 and allow EIGRP 222 routes to flow in. Which OSPF area type fulfills this design requirement?

Answer: B


NEW QUESTION # 85
Refer to the table.

A customer investigates connectivity options for a DCI between two production data centers. The solution must provide dual 10G connections between locations with no single points of failure for Day 1 operations. It must also include an option to scale for up to 20 resilient connections in the second year to accommodate isolated SAN over IP and isolated, dedicated replication IP circuits. All connectivity methods are duplex 10 Gbps. Which transport technology costs the least over two years, in the scenario?

Answer: A

Explanation:
Let's calculate Total Cost of Ownership (TCO) for 24 months based on the table and given scaling requirements:
-
Metro Ethernet:
* CAPEX = $45,000
* Installation Fee = $5,000
* OPEX = $125,000/year # $250,000 for 2 years
* Total = 45,000 + 5,000 + 250,000 = $300,000
DWDM:
* CAPEX = $250,000
* Installation Fee = $30,000
* OPEX = $100,000/year # $200,000 for 2 years
* Total = 250,000 + 30,000 + 200,000 = $480,000
CWDM:
* CAPEX = $150,000
* Installation Fee = $25,000
* OPEX = $100,000/year # $200,000 for 2 years
* Total = 150,000 + 25,000 + 200,000 = $375,000
MPLS:
* CAPEX = $50,000
* Installation Fee = $75,000
* OPEX = $150,000/year # $300,000 for 2 years
* Total = 50,000 + 75,000 + 300,000 = $425,000
-
Metro Ethernet clearly results in the lowest total cost while meeting dual 10G and scalable growth to 20 connections due to its simple provisioning and operational flexibility.
This approach fully aligns with CCDE v3.1 business-driven cost modeling principles: balancing cost, scalability, and operational simplicity.
Why other options are incorrect:
* B, C, D: All are more expensive after full 2-year calculation for the required scale.
