An organization launched an IPv6-only web portal to support IPv6-native mobile clients. Front-end instances launch in an Amazon VPC associated with an appropriate IPv6 CIDR. The VPC IPv4 CIDR is fully utilized. A single subnet exists in each of two Availability Zones with appropriately configured IPv6 CIDR associations. Auto Scaling is properly configured, and no Elastic Load Balancing is used.
Customers say the service is unavailable during peak load times. The network engineer attempts to launch an instance manually and receives the following message: “There are not enough free addresses in subnet ‘subnet-12345677’ to satisfy the requested number of instances.”
What action will resolve the availability problem?
A company has a hybrid environment that connects an on-premises data center to the AWS Cloud. The hybrid environment uses a 10 Gbps AWS Direct Connect dedicated connection. The Direct Connect connection has multiple private VIFs that terminate in multiple VPCs.
To comply with regulations, the company must encrypt all WAN traffic, regardless of the underlying transport. The company needs to implement an encryption solution that will not affect the company's bandwidth capacity.
Which solution will meet these requirements?
A company's application team is unable to launch new resources into its VPC. A network engineer discovers that the VPC has run out of usable IP addresses. The VPC CIDR block is 172.16.0.0/16.
Which additional CIDR block can the network engineer attach to the VPC?
