Question 1
A cloud engineer is receiving multiple alerts from the infrastructure monitoring agent. The alerts state that all the VMs in the public subnet are at 100% CPU utilization. However, when the engineer checks the network utilization of the VMs, the network throughput is at normal levels. Which of the following is the most likely cause of this issue?
Answer : B
A . Ransomware: Encrypts data to demand payment but doesn't typically result in sustained high CPU utilization.
B . Cryptojacking: Involves unauthorized use of VMs to mine cryptocurrency, leading to 100% CPU usage without high network activity.
C . DDoS: Causes high network throughput and latency, which are not present in this scenario.
D . Zombie instances: Refers to unused VMs consuming resources unnecessarily but doesn't explain high CPU utilization.

Question 2
A company developed an online trading platform. The engineering team selected event-based scaling for the platform's underlying resources. The platform resources scale up with every 2,000 subscribed users. The engineering team finds out that although compute utilization is low, scaling is still occurring. Which of the following statements best explains why this is the case?
Answer : D
Comprehensive and Detailed Step-by-Step
A . Event-based scaling does not scale down resources: Event-based scaling can scale both up and down depending on triggers.
B . Event-based scaling should not be triggered at the 2,000-user frequency: The frequency is a design choice but doesn't explain the behavior.
C . Event-based scaling should not track user subscriptions: Tracking users isn't inherently wrong, but it should align with resource load metrics.
D . Event-based scaling does not take resource load into account: Event-based scaling relies on predefined triggers (e.g., user count) and doesn't dynamically assess resource utilization, leading to inefficiencies.

Question 3
A write-intensive workload is having frequent performance issues. The workload is running on pay-as-you-go VMs. These VMs use SSDs and have appropriate CPU and RAM sizes. The workload writes millions of small files and has a one-year retention requirement. Which of the following actions should be taken?
Answer : A
Comprehensive and Detailed Step-by-Step
A . Use provisioned IOPS volumes: Ideal for write-intensive workloads as they provide guaranteed performance by provisioning a specific number of IOPS.
B . Increase the VM size: CPU or RAM upgrades won't significantly benefit a storage-bound workload.
C . Switch to reserved VMs: Cost-effective but doesn't address performance issues.
D . Change to ephemeral storage: Temporary storage is not suitable for workloads requiring a one-year retention policy.

Question 4
A developer is sending requests to a SaaS application. The developer becomes unable to send more requests after sending a number of them, but other developers can still send requests. Which of the following is most likely causing the issue?
Answer : C
A . Partial outage: Would affect multiple developers, not just one.
B . API throttling: Temporarily limits requests but doesn't block them entirely.
C . Rate limiting: Prevents excessive requests from a single user or system, explaining why the developer was blocked after reaching a certain threshold.
D . Service quota: Typically applies to overall service usage rather than individual user requests.

Question 5
A company has ten cloud engineers working on different manual cloud deployments. In the past, engineers have had difficulty keeping deployments consistent. Which of the following is the best method to address this issue?
Answer : C
Comprehensive and Detailed Step-by-Step
A . Deployment documentation: Helpful but does not enforce consistency or automation.
B . Service logging: Useful for monitoring but unrelated to deployment consistency.
C . Configuration as code: Automates and standardizes deployments, ensuring consistency regardless of the engineer performing the task.
D . Change ticketing: Tracks changes but doesn't enforce consistency or standardization.

Question 6
The company's IDS has reported an anomaly. The cloud engineer remotely accesses the cloud instance, runs a command, and receives the following information:
Which of the following is the most likely root cause of this anomaly?
Answer : A
The output from the 'ps' command indicates there is a process running under the UID (User ID) of 0, which is the root user, and the command that was run is '/var/www/command.py'. Given that the normal Apache processes are running under their own UID (65535), this suggests that a command was executed with root privileges that typically should not have such high-level access. This is a strong indicator of privilege escalation, where an unauthorized user or process gains elevated access to resources that are normally protected from an application or user.

Question 7
A bank informs an administrator that changes must be made to backups for long-term reporting purposes. Which of the following is the most important change the administrator
should make to satisfy these requirements?
Answer : C
For long-term reporting purposes, the most critical aspect to consider is the retention period of the backups. This is because the bank will likely require access to historical data for audit, compliance, and reporting purposes. The retention policy will need to ensure that backups are kept for the required duration, which may be several years depending on regulatory and business needs. Adjusting the retention policy will help ensure that the necessary data is preserved for as long as it is needed, without unnecessary data accumulation that could lead to higher costs and management complexity.
