The correct answer is B. Implementing deduplication would best help the administrator reduce storage costs.

Deduplication is a technique that eliminates redundant copies of data and stores only one unique instance of the data. This can reduce the amount of storage space required and lower the storage costs. Deduplication can be applied at different levels, such as file-level, block-level, or object-level. Deduplication can also improve the performance and efficiency of backup and recovery operations.

Enabling compression is another technique that can reduce storage costs, but it may not be as effective as deduplication, depending on the type and amount of data. Compression reduces the size of data by applying algorithms that remove or replace redundant or unnecessary bits. Compression can also affect the quality and accessibility of the data, depending on the compression ratio and method.

Using containers and rightsizing the VMs are techniques that can reduce compute costs, but not necessarily storage costs. Containers are lightweight and portable units of software that run on a shared operating system and include only the necessary dependencies and libraries. Containers can reduce the overhead and resource consumption of virtual machines (VMs), which require a full operating system for each instance. Rightsizing the VMs means adjusting the CPU, memory, disk, and network resources of the VMs to match their workload requirements. Rightsizing the VMs can optimize their performance and utilization, and avoid overprovisioning or underprovisioning.

Detailed Explanation:

D. Reduce the allocated memory and enable dynamic memory: Allocating excessive memory to VMs can lead to slow performance during initialization. Dynamic memory allows the system to allocate resources as needed, optimizing performance and resource use.

Deduplication is a process by which redundant data is eliminated, thus reducing the size of the dataset. Deduplication with cloud storage reduces the storage requirements, along with the amount of data to be transferred over the network, resulting in faster and more efficient data protection operations1. Deduplication can help to shrink the data footprint, lower the storage costs, and improve the performance of backup and recovery processes2. Deduplication can be applied at different levels, such as file-level, block-level, or byte-level, depending on the granularity and efficiency of the technique3. Deduplication can also be performed at different locations, such as source, target, or cloud, depending on the architecture and design of the storage system3. By implementing deduplication, a cloud administrator can achieve significant data savings and optimize the cloud storage costs4. References: Data deduplication techniques for efficient cloud storage management: a systematic review; How Data Deduplication Reduces Cloud Data Costs; How Data Deduplication Can Save Cloud Storage Costs?; Data Deduplication Overview; What is Data Deduplication and How Can it Help Reduce Cloud Costs?.

To allow communication between the on-premises and cloud subnets, the firewall traffic should be allowed to pass through the additional subnet for communication, which is 192.168.5.0/24. This subnet acts as a bridge between the two networks and should have firewall rules that permit traffic from and to both sides.

LTS stands for Long Term Support, and it is a term that refers to a version of an operating system that receives updates and security patches for a longer period of time than other versions. LTS versions are usually more stable and reliable than other versions, and they are suitable for users who want to avoid frequent changes or compatibility issues. By choosing LTS versions for the VMs that are hosted in a cloud environment, the systems administrator can ensure that the VMs receive updates for as long as possible, and benefit from the enhanced security and performance of the operating system. LTS versions are typically released every few years, and they are supported for several years after their release. For example, Ubuntu 20.04 LTS is supported until April 2025, while Ubuntu 21.04 is supported until January 2022.

An Intrusion Detection System (IDS) is a software or hardware system that monitors network traffic for malicious activity and alerts the administrator of any potential threats. An Intrusion Prevention System (IPS) is a software or hardware system that not only detects but also blocks or mitigates the malicious activity. Both IDS and IPS are essential for securing a web application in a cloud environment1.

A web proxy server is a server that acts as an intermediary between the client and the web server. It can provide caching, filtering, and authentication services, but it does not offer IDS/IPS functionality. Therefore, option A is incorrect.

Load balancing using SSI (Server Side Includes) is a technique that distributes the workload among multiple web servers by inserting dynamic content into web pages. It can improve the performance and availability of a web application, but it does not provide IDS/IPS protection. Therefore, option B is incorrect.

Implementing IDS/IPS agents on each instance running in that virtual private network is a valid solution for providing IPS protection for traffic coming from the internet. The agents can monitor and inspect the network traffic on each instance and block or report any suspicious activity to a central management console. This can prevent attacks from reaching the web application or spreading to other instances in the same network. Therefore, option C is correct.

Implementing dynamic routing is a technique that allows routers to select the best path for forwarding packets based on network conditions. It can enhance the reliability and efficiency of a network, but it does not offer IDS/IPS functionality. Therefore, option D is incorrect.

The benchmark results show that the video RAM utilization is at 99%, which is likely causing the application crashes. Video RAM is used to store graphics data and textures that are processed by the GPU. Selecting a higher vGPU profile can help allocate more video RAM to the virtual machines, which can help resolve this issue. A vGPU profile is a predefined configuration that specifies the amount of video RAM, the number of display heads, and the maximum resolution that a virtual machine can use. By selecting a higher vGPU profile, the administrator can increase the performance and stability of the high-frame-rate rendering application. References: [CompTIA Cloud+ CV0-003 Study Guide], Chapter 4, Objective 4.2: Given a scenario, troubleshoot common virtualization issues.

Detailed Explanation:

A. Connectivity issues: Legacy tools might not fully support multicloud environments, leading to potential integration challenges.

F. Lack of support: Legacy systems are often outdated and no longer maintained, which can result in a lack of vendor or community support for troubleshooting.
