To determine the correct answer, you must evaluate the requirements for installing a Nutanix NX-3460-G6 block. Each block typically occupies 2U of rack space. Since the customer has two blocks, a total of 4U is required, which fits within the available 5U rack space. Additionally, each block requires two power sockets (one for each node in the block), totaling four sockets. Since there are six available sockets, there is enough power availability. Therefore, the primary constraints are adequately met in terms of rack space and power sockets. The mention of network ports and their sufficiency is not required here, as it isn't the limiting factor based on the details provided.
