  Backup integrity is a critical aspect of data management and protection, which falls under the best practices for backups and restoration in the CompTIA Cloud+ curriculum.

• Question 334:

  A new development team requires workstations hosted in a PaaS to develop a new website. Members of the team also require remote access to the workstations using their corporate email addresses.

  Which of the following solutions will BEST meet these requirements? (Select TWO).

  A. Deploy new virtual machines.
  B. Configure email account replication.
  C. Integrate identity services.
  D. Implement a VDI solution.
  E. Migrate local VHD workstations.
  F. Create a new directory service.
  A. Deploy new virtual machines.
  C. Integrate identity services.

  ---

  Explanation

  1. To develop a new website using a PaaS, the development team needs to deploy new virtual machines (VMs) on the cloud platform. VMs are software emulations of physical computers that can run different operating systems and applications. By deploying new VMs, the development team can create a scalable and flexible environment for their website project, without having to invest in or manage physical hardware 2. To enable remote access to the workstations using their corporate email addresses, the development team needs to integrate identity services on the cloud platform. Identity services are services that provide authentication, authorization, and identity management for users and devices accessing cloud resources. By integrating identity services, the development team can use their corporate email addresses as single sign-on (SSO) credentials to access their workstations from any device and location, while ensuring security and compliance 3.

  The other options are not the best solutions for these requirements: Configuring email account replication is not necessary for remote access to the workstations. Email account replication is a process of synchronizing email accounts across different servers or locations. It can provide backup and redundancy for email services, but it does not provide authentication or identity management for remote access 4.

  Implementing a Virtual Desktop Infrastructure (VDI) solution is not a PaaS solution. VDI is a technology that allows users to access virtual desktops hosted on a centralized server. VDI can provide remote access to desktop environments, but it requires additional hardware, software, and management costs that are not included in a PaaS model 5.

  Migrating local VHD workstations is not a PaaS solution. VHD stands for Virtual Hard Disk, which is a file format that represents a virtual hard disk drive. Migrating local VHD workstations means moving the virtual hard disk files from local storage to cloud storage. This can provide backup and portability for the workstations, but it does not provide a complete cloud platform for developing and running applications 6.

  Creating a new directory service is not necessary for remote access to the workstations. A directory service is a service that stores and organizes information about users, devices, and resources on a network.

  Creating a new directory service means setting up a new database and schema for storing this information.

  This can provide identity management and access control for the network, but it does not provide authentication or SSO for remote access.

• Question 335:

  A systems administrator is provisioning VMs according to the following requirements:

  5. A VM instance needs to be present in at least two data centers.

  6. During replication, the application hosted on the VM tolerates a maximum latency of one second.

  7. When a VM is unavailable, failover must be immediate.

  Which of the following replication methods will best meet these requirements?

  A. Snapshot
  B. Transactional
  C. Live
  D. Point-in-time
  C. Live

  ---

  Explanation

  Live replication is the process of continuously copying data in real-time to ensure that an exact copy is available in another location. Given the requirement for immediate failover and the presence of the VM instance in at least two data centers, live replication is the best method to meet the one-second maximum latency tolerance and ensure immediate availability in the event of a VM becoming unavailable.

• Question 336:

  A cloud administrator recently created three servers in the cloud. The goal was to create ACLs so the servers could not communicate with each other. The servers were configured with the following IP addresses:

  

  After implementing the ACLs, the administrator confirmed that some servers are still able to reach the other servers.

  Which of the following should the administrator change to prevent the servers from being on the same network?

  A. The IP address of Server 1 to 172.16.12.36
  B. The IP address of Server 1 to 172.16.12.2
  C. The IP address of Server 2 to 172.16.12.18
  D. The IP address of Server 2 to 172.16.14.14
  B. The IP address of Server 1 to 172.16.12.2

  ---

  Explanation

  To prevent the servers from being on the same network and communicating with each other, the administrator should change the IP address of Server 1 to 172.16.12.2. This IP address is outside the subnet defined by the subnet mask 255.255.255.240, which would place Server 1 on a different subnet, preventing direct communication without routing.

• Question 337:

  Which of the following files should be used to install software with a package manager?

  A. package.json
  B. package.zip
  C. package.deb
  D. package.tar
  C. package.deb

  ---

  Explanation

  In Linux-based systems,.deb files are used by package managers like dpkg and APT (Advanced Package Tool) to install software on Debian-based distributions (e.g., Ubuntu). Package managers handle dependencies and ensure proper installation.

• Question 338:

  An organization is preparing for seasonal sales on its storefront web application.

  Which of the following approaches is best suited to meet this requirement with the minimal cost?

  A. Configuring a load balancer with a least-connections load-balancing method
  B. Enabling a scaling configuration for the identified timeline
  C. Reconfiguring the application to have more resources
  D. Deploying additional compute resources in advance to the web application pool
  B. Enabling a scaling configuration for the identified timeline

  ---

  Explanation

  Configuring scaling for the seasonal sales period allows resources to automatically adjust to demand, ensuring performance while minimizing cost compared to permanently adding or pre-deploying extra resources.

• Question 339:

  An engineer has an application running in the United States in a cloud environment. This application must be replicated into a United Kingdom cloud environment. When the application is deployed to the United Kingdom environment, there are issues acquiring a virtual machine with a GPU.

  Which of the following is the most likely reason for this issue?

  A. The route tables are misconfigured and cannot connect to virtual machines
  B. The API for creating virtual machines is being throttled
  C. The United Kingdom region has an outage
  D. The United Kingdom region does not have virtual machines that meet the requirements
  E. The United Kingdom region cannot connect to the United States region
  D. The United Kingdom region does not have virtual machines that meet the requirements

  ---

  Explanation

  Cloud providers do not offer all VM types and hardware configurations in every region. GPU-enabled virtual machines are often available only in selected regions or may have limited capacity. If the deployment in the United Kingdom cannot acquire a VM with a GPU, the most likely cause is that the region does not offer a VM that meets the application's GPU requirements.

• Question 340:

  Which of the following are best practices when working with a source control system? (Select two).

  A. Merging code often
  B. Pushing code directly to production
  C. Performing code deployment
  D. Maintaining one branch for all features
  E. Committing code often
  F. Initiating a pull request
  A. Merging code often
  E. Committing code often

  ---

  Explanation

  Best practices when working with a source control system include merging code often to ensure that changes from different team members are integrated regularly, reducing integration issues. Committing code often is also recommended to save small changes frequently, which helps in tracking changes and resolving issues more effectively.
