Final answer:
High availability for Direct Connect is achieved through redundant connections
Step-by-step explanation:
High availability for Direct Connect is achieved through redundant connections. This means that multiple physical connections are established between the Direct Connect location and the customer's network, ensuring that if one connection fails, traffic can still flow through another connection. Load balancing is not directly related to high availability for Direct Connect, but it can be used to distribute traffic evenly across redundant connections. Data compression is not specifically used to achieve high availability, but it can increase the efficiency of data transmission over the network.
