The best way to connect all the VPCs for the company that is planning its cloud architecture and wants to use a VPC for each of its three products per environment in two regions, totaling 18 VPCs, is to use a hub and spoke model. A hub and spoke model is a networking model that uses a central hub VPC that connects to multiple spoke VPCs that host the products or workloads. The hub VPC can provide common services and security policies for the spoke VPCs, such as network virtual appliances, DNS servers, firewalls, or VPN gateways. The spoke VPCs can communicate with each other through the hub VPC, using private IP addresses or peering connections. A hub and spoke model can simplify the management and scalability of the network, as well as reduce the costs and complexity of peering multiple VPCs directly.

A volume-based licensing model is a licensing model that charges the customer based on the amount of data or resources that they consume or use. A volume-based licensing model is suitable for an laaS (Infrastructure as a Service) environment, as it allows the customer to pay only for what they need and scale up or down as their demand changes. A volume-based licensing model can provide financial benefits for the customer, such as lower upfront costs, greater flexibility, and more predictable billing.QUESTION NO: 277

A cloud administrator is evaluating a solution that will limit access to authorized individuals. The solution also needs to ensure the system that connects to the environment meets patching, antivirus, and configuration requirements. Which of the following technologies would BEST meet these requirements?

A.NAC

B.EDR

C.IDS

D.HIPS

Answer: A

NAC (Network Access Control) is a technology that will limit access to authorized individuals and ensure the system that connects to the environment meets patching, antivirus, and configuration requirements. NAC can enforce policies and rules that define who, what, when, where, and how a device or a user can access a network or a cloud environment. NAC can also inspect and evaluate the security posture and compliance status of a device or a user before granting or denying access. For example, NAC can check if the device has the latest patches, antivirus software, and configuration settings, and if not, it can quarantine, remediate, or reject the device. NAC can also monitor and audit the ongoing network activity and behavior of the devices and users, and take actions if any violations or anomalies are detected.

The correct answer is D. Migrate the data to flash storage. Flash storage is a type of solid-state storage that uses flash memory to store data. Flash storage has much faster performance and lower latency than NL-SAS storage, which is a type of hard disk drive that uses nearline serial attached SCSI interface. According to the web search results, NL-SAS devices have much higher response times than flash devices123. Therefore, migrating the data to flash storage can reduce the application latency and improve the user experience. Increasing the capacity of the data storage, migrating the data to SAS storage, or increasing the CPU of the VM are not likely to solve the latency issue, as they do not address the root cause of the problem, which is the slow performance of NL-SAS storage. For more information on flash storage and its benefits, you can refer to the Dell EMC Unity: FAST Technology Overview2 or the Dell Technologies website4.

The most likely cause of the issue is A. The target system’s API functionality has been deprecated. API deprecation is the process of gracefully discontinuing an API. The process starts by first informing the customers that the API is no longer actively supported even though it will be operational and suggesting them to migrate to an alternate or latest version of the API1. However, sometimes the API functionality may change or be removed without proper notice or documentation, which can break the existing applications that rely on the API. According to the web search results, API deprecation is a common challenge for configuration management tools. Therefore, if the target system’s API functionality has been deprecated after the updates, the configuration management tool may no longer work as expected.
