A cloud administrator shortens the amount of time a backup runs. An executive in the company requires a guarantee that the backups can be restored with no data loss. Which of the following backup features should the administrator test for?
A. Encryption
B. Retention
C. Schedule
D. Integrity
Show Answer
Correct Answer: D
Explanation: To guarantee that backups can be restored with no data loss, the administrator must ensure the backup data is complete and uncorrupted. Testing backup integrity verifies that the backup can be successfully read and restored. Encryption, retention, and schedule do not confirm restorability or data accuracy.
Question 6
A new major version of a package installed on a VM was recently released. Which of the following should a cloud engineer do first before applying the upgrade?
A. Review for package dependencies
B. Raise a change request
C. Investigate for any breaking changes
D. Verify that patching the VM will not reset user data
Show Answer
Correct Answer: B
Explanation: In a formal cloud change management process (such as Cloud+), the first step before making any significant modification—like upgrading to a new major package version—is to initiate or raise a change request. This ensures the change is documented, reviewed, and approved. Activities like investigating breaking changes, dependency review, and risk/impact analysis are performed after the change request is raised as part of the assessment process.
Question 7
A social networking company operates globally. Some users from Brazil and Argentina are reporting the following error: website address was not found. Which of the following is the most likely cause of this issue?
A. Client DNS misconfiguration
B. Regional DNS provider outage
C. DNS server misconfiguration
D. DNSSEC key mismatch
Show Answer
Correct Answer: B
Explanation: The error occurs only for users in specific countries, indicating a geographically scoped problem. A regional DNS provider outage would prevent name resolution in those areas, producing a "website address not found" error. A global DNS server misconfiguration or DNSSEC issue would affect users worldwide, and a client DNS misconfiguration would not consistently impact many users in the same regions.
Question 7
A cloud engineer needs to enable monitoring on a virtual machine instance within a cloud service provider. The engineer must monitor the resources related to the amount of memory an application is utilizing. Which of the following metrics should the engineer monitor for memory as it relates to disk performance?
A. Heap utilization
B. Swap usage
C. IOPS consumption
D. Queue depth
Show Answer
Correct Answer: B
Explanation: Swap usage directly links memory pressure to disk activity. When RAM is insufficient, the OS swaps memory pages to disk, impacting disk performance. Monitoring swap usage reveals how memory utilization is affecting disk I/O, unlike heap utilization (application-level), IOPS consumption, or queue depth, which are disk metrics not specific to memory pressure.
Question 8
An administrator needs to adhere to the following requirements when moving a customer’s data to the cloud:
The new service must be geographically dispersed.
The customer should have local access to data.
Legacy applications should be accessible.
Which of the following cloud deployment models is most suitable?
A. On-premises
B. Private
C. Hybrid
D. Public
Show Answer
Correct Answer: C
Explanation: A hybrid cloud combines on‑premises resources with cloud services. This allows legacy applications to remain accessible locally, provides local data access, and leverages public cloud infrastructure for geographic dispersion. Other models fail to meet all three requirements simultaneously.
Question 8
Following a ransomware attack, the legal department at a company instructs the IT administrator to store the data from the affected virtual machines for a minimum of one year.
Which of the following is this an example of?
A. Recoverability
B. Retention
C. Encryption
D. Integrity
Show Answer
Correct Answer: B
Explanation: Storing data for a defined minimum period to satisfy legal or compliance requirements is an example of data retention. It specifies how long data must be preserved, not how it is recovered, protected, or validated.
Question 9
A cloud engineer wants to implement a monitoring solution to detect cryptojacking and other cryptomining malware on cloud instances. Which of the following metrics would most likely be used to identify the activity?
A. Disk I/O
B. Network packets
C. Average memory utilization
D. Percent of CPU utilization
Show Answer
Correct Answer: D
Explanation: Cryptomining malware performs intensive hash calculations, which causes abnormally high and sustained CPU usage. Monitoring percent of CPU utilization is the most reliable and common metric to detect cryptojacking compared to disk I/O, network packets, or memory usage.
Question 9
An organization needs to retain its data for compliance reasons but only when required. Which of the following would be the most cost-effective type of tiered storage?
A. Warm
B. Hot
C. Archive
D. Cold
Show Answer
Correct Answer: C
Explanation: Archive storage is designed for long-term retention at the lowest cost, with infrequent access and higher retrieval times, which aligns with compliance data that must be kept but only accessed when required. Hot, warm, and cold tiers are more expensive because they are optimized for more frequent or faster access.
Question 10
A cloud solutions architect needs to design a solution that will collect a report and upload it to an object storage service every time a virtual machine is gracefully or non-gracefully stopped. Which of the following will best satisfy this requirement?
A. An event-driven architecture that will send a message when the VM shuts down to a log-collecting function that extracts and uploads the log directly from the storage volume
B. Creating a webhook that will trigger on VM shutdown API calls and upload the requested files from the volume attached to the VM into the object-defined storage service
C. An API of the object-defined storage service that will scrape the stopped VM disk and self-upload the required files as objects
D. A script embedded on the stopping VM's OS that will upload the logs on system shutdown
Show Answer
Correct Answer: A
Explanation: The requirement includes both graceful and non-graceful VM stops, which cannot be reliably handled by an in-guest shutdown script. An event-driven architecture that reacts to VM lifecycle events at the infrastructure level can trigger regardless of how the VM stops. A separate log-collecting function can then access the attached storage volume and upload the report to object storage, making option A the most robust and appropriate solution.
Question 10
Which of the following container storage types loses data after a restart?
A. Object
B. Persistent volume
C. Ephemeral
D. Block
Show Answer
Correct Answer: C
Explanation: Ephemeral storage is tied to the lifecycle of a container or pod. When the container restarts or is recreated, this storage is cleared, so any data stored there is lost. Object, block, and persistent volumes are designed to retain data across restarts.
