NEW QUESTION # 11
A cloud administrator has created a new asynchronous workflow lo deploy VMs to the cloud in bulk. When the workflow is tested for a single VM, it completes successfully. However, if the workflow is used to create 50 VMs at once, the job fails. Which of the following is the MOST likely cause of the issue? (Choose two.)
- A. Billing issues with the cloud provider
- B. No connectivity to the public cloud
- C. Expired API token
- D. Incorrect permissions
- E. Disabled autoscaling
- F. Insufficient storage
Answer: C,F
Explanation:
The most likely causes of the issue where the new asynchronous workflow fails to create 50 VMs at once in the public cloud are insufficient storage and expired API token. Insufficient storage means that there is not enough disk space available in the public cloud to accommodate all the VMs that are being created simultaneously. This could result in errors or failures during the provisioning process. Expired API token means that the authentication credential that is used by the workflow to communicate with the public cloud service has expired or become invalid. This could result in errors or failures during the API calls or requests.

An organization is hosting a DNS domain with private and public IP ranges.
Which of the following should be implemented to achieve ease of management?
- A. An IPAM solution
- B. A SDN solution
- C. A CDN solution
- D. Network peering
Answer: A
Explanation:
An IP address management (IPAM) solution is a type of tool or system that automates and standardizes the allocation, tracking, and management of IP addresses in an IP network. An IPAM solution can help achieve ease of management for hosting a DNS domain with private and public IP ranges, as it can simplify and centralize the process of assigning and updating IP addresses for different DNS records or zones without manual intervention or errors. An IPAM solution can also help optimize DNS performance and security, as it can monitor and report any issues or conflicts related to IP addresses or DNS records. Reference: CompTIA Cloud+ Certification Exam Objectives, page 15, section 2.8
NEW QUESTION # 14
A systems administrator is working within a private cloud environment. Over time. random 4K read/write speeds on all VMS in the environment slow down until the VMS are completely unusable, with disk speeds of less than 1MBps. The administrator has gathered the information below:
* There is no correlation between the slowdown and VM/hypervisor resource utilization.
* The network is rated to 40Gbps and utilization is between 1-5%.
* The hypervisors use hundreds of NFSv3 mounts to the same storage appliance, one per VM.
* The VMS on each hypervisor become unresponsive after two weeks of uptime.
* The unresponsiveness is resolved by moving slow VMS onto a rebooted hypervisor.
Which of the following solutions will MOST likely resolve this issue?
- A. Configure jumbo frames on the hypervisors and storage.
- B. Increase CPU/RAM resources on affected VMS.
- C. Reduce the number of NFSv3 mounts to one.
- D. Increase caching on the storage appliance.
Answer: C
Explanation:
Explanation
The correct answer is D. Reduce the number of NFSv3 mounts to one.
NFSv3 is a network file system protocol that allows clients to access files stored on a remote server. NFSv3 uses TCP or UDP as the transport layer protocol, and typically runs on port 20491.
One of the known issues with NFSv3 mounts is that they can cause performance degradation and unresponsiveness on the client side if there are too many mounts or if there are network connectivity problems.
This is because NFSv3 does not handle connection failures or timeouts gracefully, and may keep retrying to access the server indefinitely, blocking other processes or threads. This can result in slow disk speeds, high CPU usage, and system hangs23.
Therefore, one of the possible solutions to this issue is to reduce the number of NFSv3 mounts to one per hypervisor, instead of one per VM. This way, the hypervisor can manage the access to the shared storage appliance more efficiently, and avoid creating too many TCP connections or UDP packets that may overload the network or the server. Reducing the number of NFSv3 mounts can also simplify the configuration and troubleshooting of the network file system.
Increasing caching on the storage appliance may improve the read performance of the NFSv3 mounts, but it will not solve the underlying issue of connection failures or timeouts. Caching may also introduce data inconsistency or corruption issues if the cache is not synchronized with the server.
Configuring jumbo frames on the hypervisors and storage may improve the network throughput and efficiency of the NFSv3 mounts, but it will not solve the underlying issue of connection failures or timeouts. Jumbo frames are larger than standard Ethernet frames, and require that all devices on the network path support them.
Jumbo frames may also introduce fragmentation or compatibility issues if they are not configured properly.
Increasing CPU/RAM resources on affected VMs may improve their performance in general, but it will not solve the underlying issue of connection failures or timeouts. Increasing CPU/RAM resources may also be costly and wasteful if they are not needed for other purposes.
NEW QUESTION # 15

NEW QUESTION # 16
A systems administrator is troubleshooting a performance issue with a virtual database server. The administrator has identified the issue as being disk related and believes the cause is a lack of IOPS on the existing spinning disk storage. Which of the following should the administrator do NEXT to resolve this issue?
- A. Upgrade the virtual database server.
- B. Document the findings and place them in a shared knowledge base.
- C. Move the virtual machine to flash storage and test again.
- D. Check if other machines on the same storage are having issues.
Answer: C
Explanation:
Explanation
Moving the virtual machine to flash storage and testing again is what the administrator should do next to resolve the issue of disk-related performance issue with a virtual database server that has been identified as being caused by a lack of IOPS on the existing spinning disk storage. IOPS (Input/Output Operations Per Second) is a measure of how fast a storage device can read and write data. IOPS can affect performance of a virtual database server by determining how quickly it can access and process data from storage. Spinning disk storage is a type of storage device that uses rotating magnetic disks to store data. Spinning disk storage has lower IOPS than flash storage, which is a type of storage device that uses solid-state memory chips to store data. Flash storage has higher IOPS than spinning disk storage, which means that it can read and write data faster and more efficiently than spinning disk storage. Moving the virtual machine to flash storage and testing again can help to resolve the issue by increasing the IOPS and improving the performance of the virtual database server.
NEW QUESTION # 17

NEW QUESTION # 18
A cloud architect is deploying a web application that contains many large images and will be accessed on two continents. Which of the following will MOST improve the user experience while keeping costs low?
- A. Implement web servers in both continents and set up a VPN between the VPCs.
- B. Implement a replica of the entire solution on every continent.
- C. Implement a CDN and offload the images to an object storage.
- D. Implement web servers on both continents and peer the VPCs.
Answer: C
Explanation:
A CDN (content delivery network) is a system of distributed servers that deliver web content to users based on their geographic location, the origin of the web page, and the content delivery server1. A CDN can improve the user experience by reducing the latency, bandwidth, and load on the origin server. By offloading the images to an object storage, such as Google Cloud Storage or Amazon S3, the web application can save costs and improve performance by storing and serving the images from a CDN edge location that is closer to the user2. A CDN can also provide caching, compression, and security features for the web content3.

NEW QUESTION # 20
A company has entered into a business relationship with another organization and needs to provide access to internal resources through directory services. Which of the following should a systems administrator implement?
- A. VPN
- B. SSH
- C. sso
- D. SAML
Answer: A
Explanation:
Explanation
The answer is B. A VPN tunnel. A VPN tunnel is a secure and encrypted connection between two networks over a public network, such as the Internet. A VPN tunnel can help protect data in transit by encrypting it before it leaves the company's network and decrypting it when it reaches the public cloud service provider. A VPN tunnel can also authenticate the endpoints and verify the integrity of the data.
Some possible sources of information about VPN tunnels are:

NEW QUESTION # 21
A systems administrator is troubleshooting performance issues with a Windows VDI environment. Users have reported that VDI performance is very slow at the start of the workday, but the performance is fine during the rest of the day. Which of the following is the MOST likely cause of the issue? (Choose two.)
- A. License issues
- B. RAM usage
- C. Insufficient GPU resources
- D. Disk I/O limits
- E. CPU oversubscription
- F. Affinity rule
Answer: D,E
Explanation:
Disk I/O limits are restrictions or controls that limit the amount of disk input/output operations per second (IOPS) that a VM can perform on a storage device or system. CPU oversubscription is a situation where more CPU resources are allocated to VMs than are physically available on the host or server. Disk I/O limits and CPU oversubscription are most likely to cause VDI performance being very slow at the start of the workday, but fine during the rest of the day, as they can create bottlenecks or contention for disk and CPU resources when multiple users log in or launch their VDI sessions at the same time, resulting in increased latency or reduced throughput for VDI operations. Reference: CompTIA Cloud+ Certification Exam Objectives, page 9, section 1.4
NEW QUESTION # 22

NEW QUESTION # 24
A systems administrator is deploying a new storage array for backups. The array provides 1PB of raw disk space and uses 14TB nearline SAS drives. The solution must tolerate at least two failed drives in a single RAID set.
Which of the following RAID levels satisfies this requirement?
- A. RAID 1
- B. RAID 10
- C. RAID 0
- D. RAID 6
- E. RAID 5
Answer: D
Explanation:
Explanation
RAID 6 is a type of RAID level that uses block-level striping with two parity blocks distributed across all member disks. RAID 6 can provide redundancy and fault tolerance, as it can survive the failure of up to two disks without losing any data. RAID 6 can also support large data sets and high-capacity disks, as it can offer more usable space and better performance than other RAID levels with similar features, such as RAID 5 or RAID 10. RAID 6 is the best RAID level for a systems administrator to use when deploying a new storage array for backups that provides 1PB of raw disk space and uses 14TB nearline SAS drives and must tolerate at least two failed drives in a single RAID set. References: CompTIA Cloud+ Certification Exam Objectives, page 9, section 1.4

NEW QUESTION # 27
A systems administrator deployed a new web application in a public cloud and would like to test it, but the company's network firewall is only allowing outside connections to the cloud provider network using TCP port 22. While waiting for the network administrator to open the required ports, which of the following actions should the systems administrator take to test the new application? (Select two).
- A. Open a browser using the localhost IP address.
- B. Create a VPN tunnel.
- C. Create an IPSec tunnel.
- D. Open a browser using the default gateway IP address.
- E. Create a SSH tunnel.
- F. Create a GRE tunnel.
Answer: B,E
Explanation:
To test the new web application in the public cloud, the systems administrator should create a replica database, synchronize the data, and switch to the new instance, and create a SSH tunnel. Creating a replica database can help minimize the downtime and ensure data consistency during the migration. Synchronizing the data can help keep the replica database up to date with the original database. Switching to the new instance can help activate the new web application in the public cloud. Creating a SSH tunnel can help bypass the network firewall and access the web application using TCP port 22. SSH is a secure protocol that can create encrypted tunnels between the local and remote hosts. By creating a SSH tunnel, the systems administrator can forward the web application traffic through the tunnel and test it using a web browser. Reference: [CompTIA Cloud+ CV0-003 Certification Study Guide], Chapter 7, Objective 7.1: Given a scenario, migrate applications and data to the cloud.
