To identify DDoS attacks against a CMS service, a cloud engineer should monitor network flow logs. These logs provide data about the IP traffic going to and from network interfaces in a public cloud, which is essential for detecting the increased traffic volumes typically associated with DDoS attacks.

The developer should request an increase of the instance quota from the cloud provider. Cloud services often have a limit on the number of instances that can be created, which is known as an instance quota. If the load balancer is successfully created but the number of web servers is limited to 100, it suggests that the quota has been reached. Increasing the quota will allow the creation of additional web server instances up to the desired number.

The scenario reflects an understanding of cloud resource management and limitations, which is a part of the CompTIA Cloud+ curriculum, specifically under the domain of Management and Technical Operations.

Hot storage using Solid State Drives (SSD) is designed for data that needs to be accessed frequently and quickly. SSDs provide faster access times compared to HDDs, making them suitable for high-availability and speed-critical files, such as those currently in use or requiring rapid access.

An HTTP 403 response indicates the request was forbidden—the caller authenticated but does not have sufficient authorization to perform the requested action. In CompTIA Cloud+ (CV0-004) objectives related to identity and access management, automation, and troubleshooting, API-based provisioning failures should be mapped to common HTTP response categories: 4xx errors generally indicate client-side issues such as malformed requests or insufficient permissions, while 5xx errors more often indicate service-side problems. Because the error explicitly shows “Response 403” during storage API provisioning, the script is attempting to create or attach storage resources (such as managed disks) without the required IAM/RBAC privileges (e.g., missing rights to create disks, write to a resource group/project, or attach storage to compute).

A partial outage (B) would more likely produce 5xx responses or provider status alerts, not a consistent 403. Functionality deprecation (C) commonly results in 410 Gone or explicit deprecation messages. Sizing issues (D) usually show quota/limit errors (often 429/LimitExceeded) or validation errors (400) describing unsupported disk counts or VM types. Therefore, permission issues is the best answer.
