NEW QUESTION # 51
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: A


NEW QUESTION # 52
Software-defined networking architecture is used for cost-effective, adaptable, and easily manageable applications. In which two software-defined networks is SDN commonly used? (Choose two.)

Answer: A,C


NEW QUESTION # 53

NEW QUESTION # 54
Refer to the exhibit.

This network is running OSPF as the routing protocol. The internal networks are being advertised in OSPF.
London and Rome are using the direct link to reach each other although the transfer rates are better via Barcelona. Which OSPF design change allows OSPF to calculate the proper costs?

Answer: C

Explanation:
A (Change OSPF reference bandwidth): OSPF calculates path cost based on interface bandwidth using a formula where cost = reference bandwidth / interface bandwidth. The default OSPF reference bandwidth is
100 Mbps, which causes all faster links (1 Gbps and above) to appear with the same minimum cost.
Updating the reference bandwidth (e.g., to 10000 or higher) allows OSPF to assign accurate costs to faster links, enabling proper path selection that reflects real link capacities.
Other options explained:
B: Filtering is not the correct method for path optimization.
C: Changing interface bandwidth values is a workaround but not scalable or recommended compared to updating the reference bandwidth globally.
D: Summarization addresses prefix aggregation, not cost calculation.
