An organization is hosting a seminar with eight individuals who need to connect to their own dedicated VM.
The technician used the following VM configurations:
IP address: DHCP
NIC: 1Gbps
Network: 10.1.10.0/29
Several users are unable to access their VMs.
Which of the following best describes the reason?
- A . Not enough addresses are available.
- B . The routes are misconfigured.
- C . Too much traffic is on the network.
- D . DHCP is not working correctly on the VM.
A
Explanation:
The network is configured with a subnet of /29, which provides only 6 usable IP addresses after accounting for the network and broadcast addresses. With eight individuals needing to connect to their own dedicated VMs, there are not enough IP addresses available to assign to each VM, leading to several users being unable to access their VMs. This issue is not related to misconfigured routes, network traffic, or DHCP functionality, but rather the limited number of IP addresses available in the given subnet.
Which of the following integration systems would best reduce unnecessary network traffic by allowing data to travel bidirectionally and facilitating real-time results for developers who need to display critical information within applications?
- A . REST API
- B . RPC
- C . GraphQL
- D . Web sockets
D
Explanation:
Web sockets provide a full-duplex communication channel over a single, long-lived connection, allowing data to flow bidirectionally between a client and a server. This is ideal for real-time applications where developers need to display critical information without unnecessary network overhead, as it reduces the need for repetitive HTTP requests and allows for more efficient, instantaneous data updates and interactions.
An administrator is setting up a cloud backup solution that requires the following features:
• Cost effective
• Granular recovery
• Multilocation
Which of the following backup types best meets these requirements?
- A . Off-site, full, incremental, and differential
- B . Cloud site, full, and differential
- C . On-site. full, and incremental
- D . On-site. full, and differential
A
Explanation:
An off-site cloud backup solution that offers full, incremental, and differential backups would best meet the requirements of being cost-effective, allowing granular recovery, and supporting multi-location storage. This combination allows for comprehensive backup strategies that can be tailored to the company’s needs while optimizing storage costs.
Reference: Backup strategies, including full, incremental, and differential backups, are an integral part of data management and protection strategies discussed in the CompTIA Cloud+ objectives.

Which of the following situations would require a project manager to revise the communication plan during a project’s execution?
- A . A change is approved that impacts the project schedule and budget
- B . The test results are not as expected
- C . The team is unclear which meetings they should attend
- D . A stakeholder requests some changes to the scope
C
Explanation:
If team members are confused about which meetings to attend, this indicates a flaw in the communication plan. Revising the plan ensures clear expectations on who participates in which communication events. Scope or schedule changes don’t automatically require altering the communication plan.

A cloud administrator needs to distribute workloads across remote data centers for redundancy reasons.
Which of the following deployment strategies would eliminate downtime, accelerate deployment, and remain cost efficient?
- A . In-place
- B . Rolling
- C . Blue-green
- D . Canary
C
Explanation:
Blue-green deployment is the strategy that can eliminate downtime, accelerate deployment, and remain cost-efficient. It involves running two identical production environments, only one of which is live at any given time (blue or green). When it’s time to deploy, the new version is released to the inactive environment (green), which is then thoroughly tested. Once ready, the traffic is switched over, making the green environment live.
Reference: Deployment strategies and their impact on operations are a significant topic within the CompTIA Cloud+ examination objectives.
Which of the following is a difference between a SAN and a NAS?
- A . A SAN works only with fiber-based networks.
- B . A SAN works with any Ethernet-based network.
- C . A NAS uses a faster protocol than a SAN
- D . A NAS uses a slower protocol than a SAN.
D
Explanation:
A NAS (Network Attached Storage) typically uses file-level protocols such as NFS or SMB, which are generally considered slower and less efficient than the block-level protocols used by SANs (Storage Area Networks), such as iSCSI or Fibre Channel. SANs are designed for high performance and low latency, making them more suitable for applications requiring fast and efficient storage access.
A cloud developer needs to update a REST API endpoint to resolve a defect.
When too many users attempt to call the API simultaneously, the following message is displayed:
Error: Request Timeout – Please Try Again Later
Which of the following concepts should the developer consider to resolve this error?
- A . Server patch
- B . TLS encryption
- C . Rate limiting
- D . Permission issues
C
Explanation:
To resolve the issue of a REST API endpoint timing out when too many users attempt to call the API simultaneously, the developer should consider implementing rate limiting. Rate limiting controls the number of requests a user can submit in a given amount of time, preventing overuse of the API resources and ensuring availability for all users.

A systems administrator is configuring backups on a VM and needs the process to run as quickly as possible, reducing the bandwidth on the network during all times from Monday through Saturday. In the event of data corruption, the management team expects the mean time to recovery to be as low as possible.
Which of the following backup methods can the administrator use to accomplish these goals?
- A . Incremental backup daily to the cloud
- B . Full backup on Sunday and incremental backups on all other days of the week
- C . Differential backup daily to the cloud
- D . Incremental backups during off-hours on Monday, Wednesday, and Friday
B
Explanation:
To achieve a quick backup process and reduce bandwidth use, the administrator should perform a Full backup on Sunday and incremental backups on all other days of the week. This method ensures that only the changes made since the last full backup are copied, reducing the amount of data that needs to be transferred each time, and thus the time and bandwidth required.

A company’s engineering department is conducting a month-long test on the scalability of an in-house-developed software that requires a cluster of 100 or more servers.
Which of the following models is the best to use?
- A . PaaS
- B . SaaS
- C . DBaaS
- D . laaS
D
Explanation:
For testing the scalability of an in-house-developed software that requires a cluster of 100 or more servers, Infrastructure as a Service (IaaS) is the best model. IaaS provides the necessary compute resources and allows the engineering department to configure the environment as needed for their specific test without the constraints that might be present in PaaS or SaaS offerings.
