An administrator used a script that worked in the past to create and tag five virtual machines. All of the virtual machines have been created: however, the administrator sees the following results: { tags: [ ] } Which of the following is the most likely reason for this result?

• API throttling

• Service quotas

• Command deprecation

• Compatibility issues

which of the following types of storage provides the greatest performance advantage for a traditional relational database?

• File

• Object

• Block

• Ephemeral

A cloud engineer is troubleshooting an application that consumes multiple third-party REST APIs. The application is randomly experiencing high latency. Which of the following would best help determine the source of the latency?

• Configuring centralized logging to analyze HTTP requests

• Running a flow log on the network to analyze the packets

• Configuring an API gateway to track all incoming requests

• Enabling tracing to detect HTTP response times and codes

A cloud developer is creating a static website that customers will be accessing globally. Which of the following services will help reduce latency?

• VPC

• Application load balancer

• CDN

• API gateway

An e-commerce store is preparing for an annual holiday sale. Previously, this sale has increased the number of transactions between two and ten times the normal level of transactions. A cloud administrator wants to implement a process to scale the web server seamlessly. The goal is to automate changes only when necessary and with minimal cost. Which of the following scaling approaches should the administrator use?

• Scale horizontally with additional web servers to provide redundancy.

• Allow the load to trigger adjustments to the resources.

• When traffic increases, adjust the resources using the cloud portal.

• Schedule the environment to scale resources before the sale begins.

A cloud engineer has provisioned a VM for a high-frequency trading application. After the VM is put into production, users report high latency in trades. The engineer checks the last six hours of VM metrics and sees the following: * CPU utilization is between 30% to 60%. * NetworkIn is between 50Kbps and 70Kbps. * NetworkOut is between 3.000Kpbs and 5.000Kbps. * DiskReadOps is at 30. * DiskWriteOps is at 70 * Memory utilization is between 50% and 70%. Which of the following steps should the engineer take next to solve the latency issue?

• Move to a network-optimized instance type as the network throughput is not enough.

• Modify the disk IOPS to a higher value as the disk IO is being bottlenecked at 100 IOPS.

• Increase the memory of the instance as the high-frequency trading application requires more RAM.

• Increase the instance size to allocate more vCPUs as the CPU utilization is very high.

A cloud solution needs to be replaced without interruptions. The replacement process can be completed in phases, but the cost should be kept as low as possible. Which of the following is the best strategy to implement?

• Blue-green

• Rolling

• In-place

• Canary

A customer's facility is located in an area where natural disasters happen frequently. The customer requires the following: * Data resiliency due to exposure to frequent natural disasters * Data localization because of privacy regulations in the country * High availability Which of the following cloud resources should be provisioned to meet these requirements?

• Storage in a separate data center located in same region

• An on-premises private cloud carrying duplicate data

• Storage in an availability zone outside the region

• Storage in the same availability zone as the primary data

A customer relationship management application, which is hosted in a public cloud IaaS network, is vulnerable to a remote command execution vulnerability. Which of the following is the best solution for the security engineer to implement to prevent the application from being exploited by basic attacks?

• IPS

• ACL

• DLP

• WAF

A cloud engineer wants to implement a disaster recovery strategy that: . Is cost-effective. . Reduces the amount of data loss in case of a disaster. . Enables recovery with the least amount of downtime. Which of the following disaster recovery strategies best describes what the cloud engineer wants to achieve?

• Cold site

• Off site

• Warm site

• Hot site
