Anthos unifies the management of infrastructure and applications across on-premises, edge, and in multiple public clouds with a Google Cloud-backed control plane for consistent operation at scale.

The correct answer is C. Firewall rules. Here's why:
* Context of the Question: The organization wants to control what types of network traffic are allowed to enter and leave its network and access its applications.
* Google Cloud Product Relevance:
* Firewall rules are security settings used to control the flow of traffic to and from instances or resources in a network. They define which traffic is allowed or denied based on parameters such as IP address, protocol, and port.
* Firewall rules are essential for protecting applications from unauthorized access and for ensuring that only trusted traffic is permitted.
* Why Not Other Options:
* A. Encryption keys: Encryption keys are used for data protection and encryption but do not control network traffic.
* B. 2-Step Verification: This enhances account security by requiring a second form of authentication but does not control network traffic.
* D. Privileged access: This refers to managing access rights for administrative tasks and is not related to controlling network traffic.

Compute Engine lets you purchase committed use contracts in return for deeply discounted prices for VM usage. These discounts are referred to as committed use discounts. Committed use discounts are ideal for workloads with predictable resource needs. When you purchase a committed use contract, you purchase Compute Engine resources-such as vCPUs, memory, GPUs, local SSDs, and sole-tenant nodes-at a discounted price in return for committing to paying for those resources for 1 year or 3 years. The discount is up to 57% for most resources like machine types or GPUs. The discount is up to 70% for memory-optimized machine types.
