A systems administrator has finished installing monthly updates to servers in a cloud environment. The administrator notices certain portions of the playbooks are no longer functioning. Executing the playbook commands manually on a server does not work as well. There are no other reports of issues. Which of the following is the MOST likely cause of this issue?
Correct Answer: E
Deprecated features are features that are no longer supported or recommended by the software vendor or provider. They may be removed or replaced by newer features in future updates or versions. If a playbook relies on deprecated features, it may stop functioning after an update or patch is applied to the software. The administrator should check the release notes or documentation of the software to identify and replace any deprecated features in the playbook.
Question 12
A cloud administrator is given a requirement to maintain a copy of all system logs for seven years. All servers are deployed in a public cloud provider's environment. Which of the following is the MOST cost-efficient solution for retaining these logs?
Correct Answer: C
Question 13
A company has a web application that is accessed around the world. An administrator has been notified of performance issues regarding the application. Which of the following will BEST improve performance?
Correct Answer: C
The correct answer is C. CDN. A CDN, or content delivery network, is a group of servers spread out over a region or around the world that work together to speed up content delivery on the web. The servers in a CDN temporarily store (or cache) webpage content like images, HTML, JavaScript, and video. They send the cached content to users who load the webpage1. A CDN can improve the performance of a web application that is accessed around the world by: Decreasing the distance between where content is stored and where it needs to go. A CDN can serve content from the server that is closest to the user, reducing network latency and bandwidth consumption. Reducing file sizes to increase load speed. A CDN can employ techniques such as compression, minification, and image optimization to reduce the amount of data that needs to be transferred. Optimizing server infrastructure to respond to user requests more quickly. A CDN can use hardware and software enhancements such as solid-state hard drives, load balancing, and caching algorithms to improve the efficiency and reliability of the servers12. IPAM, or IP address management, is a method for planning, tracking, and managing the IP address space used in a network. IPAM does not directly affect the performance of a web application. SDN, or software-defined networking, is a technology that allows network administrators to dynamically configure and control network resources using software applications. SDN can improve the flexibility and scalability of a network, but it does not necessarily improve the performance of a web application. VPN, or virtual private network, is a technology that creates a secure and encrypted connection between a device and a network over the internet. VPN can enhance the privacy and security of a web application, but it does not improve its performance. In fact, VPN may introduce some overhead and latency due to encryption and decryption processes3.
Question 14
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).
Correct Answer: A,C
Explanation A Platform-as-a-Service (PaaS) is a cloud computing model that provides customers a complete cloud platform-hardware, software, and infrastructure-for developing, running, and managing applications without the cost, complexity, and inflexibility that often comes with building and maintaining that platform on-premises1. 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 hardware2. 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 compliance3. 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 access4. 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 model5. 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 applications6. 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 15
A cloud solutions architect has received guidance to migrate an application from on premises to a public cloud. Which of the following requirements will help predict the operational expenditures in the cloud?
Correct Answer: B
Maximum resource consumption is what will help predict the operational expenditures in the cloud for an application that is being migrated from on premises to a public cloud provider. Operational expenditures are the ongoing costs of running and maintaining a system or service, such as cloud resources or services. Operational expenditures can vary depending on various factors, such as usage, demand, performance, etc. Maximum resource consumption is the highest amount of resources or capacity that are used or consumed by a system or service during peak periods of activity or load. Maximum resource consumption can help predict operational expenditures in the cloud by providing information such as: Resource type: This indicates what type of resources are used or consumed by the system or service, such as compute, storage, network, etc. Resource amount: This indicates how much of each resource type are used or consumed by the system or service, such as CPU cores, memory, disk space, bandwidth, etc. Resource price: This indicates how much each resource type costs in the cloud provider's pricing model, such as per hour, per GB, per Mbps, etc.
