To allow database traffic we need to ___ a port in the firewall.
You open a port to permit traffic through a firewall on that port number. It is the standard collocation: "open port 5432". "Unlock", "free", and "release" are not used for ports. Its opposite is close a port. Mastering open/close a port is essential for talking about network access and security groups.

We should ___ the office IP so only trusted ranges can connect.
To whitelist an IP (increasingly "allow-list") means to add an address to the set permitted to access a resource. It is the long-standing collocation: "whitelist the CI server's IP". "Greenlist" and "passlist" are not standard. Both "whitelist" and the more inclusive "allow-list" are accepted; either pairs with IP, domain, or range to express access control.

The load balancer will ___ traffic to the nearest region.
To route traffic means to direct network requests along a chosen path or to a chosen destination. It is the core networking collocation: "route traffic to healthy nodes". "Drive", "steer round", and "push along" are not technical terms. Route pairs with traffic, requests, and packets, and underpins discussions of load balancing and DNS.

We can ___ the two VPCs so they communicate privately.
To peer a network (VPC peering) means to connect two networks so resources can talk over private addresses. It is the cloud-specific collocation: "peer the VPCs". "Pair", "link up", and "bridge over" are not the precise term. Peer pairs with network, VPC, and connection, and is key to multi-network architecture.

The load balancer will ___ at the edge to offload encryption.
To terminate TLS means to decrypt encrypted connections at a specific point (such as a load balancer) so backends receive plain traffic. It is the standard security collocation: "terminate TLS at the edge". "Finish", "stop", and "cut TLS" are not used. Terminate pairs with TLS/SSL and connection, and is central to discussing encryption and certificates.
