• Question 271:

  An organization is required to set a custom registry key on the guest operating system.

  Which of the following should the organization implement to facilitate this requirement?

  A. A configuration management solution

  B. A log and event monitoring solution

  C. A file integrity check solution

  D. An operating system ACL

  Correct Answer: A

  A configuration management solution is a type of tool or system that automates and standardizes the configuration and deployment of cloud resources or services according to predefined policies or rules. A configuration management solution can help set a custom registry key on the guest operating system in an IaaS instance, as it can apply the desired registry setting to one or more virtual machines (VMs) without manual intervention or scripting. A configuration management solution can also help maintain consistency, compliance, and security of cloud configurations by monitoring and enforcing the desired state.

  A. GPU

  B. CPU

  C. Storage

  D. Memory

  Correct Answer: A

  Checking the GPU (Graphics Processing Unit) is the first thing that the VDI administrator should do to optimize the performance of the VDI infrastructure for rendering tasks. GPU is a specialized hardware device that accelerates graphics processing and rendering. GPU can improve the user experience and performance of VDI applications that require intensive graphics processing, such as drafting, gaming, video editing, etc.

• Question 273:

  A marketing team is using a SaaS-based service to send emails to large groups of potential customers. The internally managed CRM system is configured to generate a list of target customers automatically on a weekly basis, and then use that list to send emails to each customer as part of a marketing campaign. Last week, the first email campaign sent emails successfully to 3,000 potential customers. This week, the email campaign attempted to send out 50,000 emails, but only 10,000 were sent.

  Which of the following is the MOST likely reason for not sending all the emails?

  A. API request limit

  B. Incorrect billing account

  C. Misconfigured auto-scaling

  D. Bandwidth limitation

  Correct Answer: A

  An API request limit is a restriction on the number of requests that can be made to a web service or application programming interface (API) within a certain time period. API request limits are often used by SaaS-based services to control the usage and traffic of their customers and prevent overloading or abuse of their resources. An API request limit can cause a failure to send all the emails if the marketing team exceeds the number of requests allowed by the SaaS-based service in a week. The service may reject or block any requests that go beyond the limit, resulting in fewer emails being sent than expected.

• Question 274:

  A systems administrator is building a new virtualization cluster. The cluster consists of five virtual hosts, which each have flash and spinning disks. This storage is shared among all the virtual hosts, where a virtual machine running on one host may store data on another host.

  This is an example of:

  A. a storage area network

  B. a network file system

  C. hyperconverged storage

  D. thick-provisioned disks

  Correct Answer: C

  Hyperconverged storage is a type of storage architecture that combines compute, storage, and network resources into a single system or appliance. Hyperconverged storage uses software-defined storage (SDS) to pool and share the local storage of each node in the cluster, creating a distributed storage system that can be accessed by any node or virtual machine in the cluster. Hyperconverged storage can provide high performance, scalability, and efficiency for virtualized environments. The scenario of building a new virtualization cluster with five virtual hosts that share their flash and spinning disks among all the virtual hosts is an example of hyperconverged storage.

• Question 275:

  An administrator is performing an in-place upgrade on a quest VM operating system.

  Which of the following can be performed as a quick method to roll back to an earlier state, if necessary?

  A. A configuration file backup

  B. A full backup of the database

  C. A differential backup

  D. A VM-level snapshot

  Correct Answer: D

  Reference: https://cloud.google.com/compute/docs/tutorials/performing-in-place-upgrade-windows-serverA VM-level snapshot is a point-in-time copy of the state and data of a virtual machine (VM). A VM-level snapshot can be used as a quick method to roll back to an earlier state, if necessary, as it can restore the VM to the exact condition it was in when the snapshot was taken. A VM-level snapshot can be useful for performing an in-place upgrade on a guest VM operating system, as it can allow the administrator to revert to the previous operating system version in case of any issues or errors.

• Question 277:

  An organization has multiple VLANs configured to segregate the network traffic. Following is the breakdown of the network segmentation:

  1.

  Production traffic (10.10.0.0/24)

  2.

  Network backup (10.20.0.0/25)

  3.

  Virtual IP network (10.20.0.128/25)

  The following configuration exists on the server:

  

  The backup administrator observes that the weekly backup is failing for this server. Which of the following commands should the administrator run to identify the issue?

  A. ROUTE PRINT

  B. NETSTAT-A

  C. IPCONFIG /ALL

  D. NET SM

  Correct Answer: A

  ROUTE PRINT is a command that displays the routing table of a system, which shows the destination network, the gateway, the interface, and the metric for each route. ROUTE PRINT can help identify the issue of the weekly backup failing for this server, as it can show if there is a valid route to the network backup segment (10.20.0.0/25) from the production traffic segment (10.10.0.0/24). If there is no route or an incorrect route, the backup will fail to reach the destination. The administrator can use ROUTE PRINT to verify and troubleshoot the routing configuration of the server.

• Question 278:

  A systems administrator needs to configure an email client to ensure data integrity of the email messages.

  Which of the following provides the BEST mechanism to achieve this goal?

  A. Cyclic redundancy check

  B. SHA-1 hashes

  C. SHA-256 hashes

  D. Digital signature

  Correct Answer: D

  A digital signature is a type of cryptographic technique that verifies the authenticity, integrity, and non-repudiation of an electronic message or document. A digital signature can help configure an email client to ensure data integrity of the email messages, as it can prove that the email message has not been altered or tampered with during transmission by using a mathematical algorithm to generate a unique code (signature) based on the content and identity of the sender. A digital signature can also help prevent spoofing, phishing, or impersonation attacks, as it can confirm that the email message originates from a legitimate source.

• Question 279:

  A cloud engineer is responsible for managing a public cloud environment. There is currently one virtual network that is used to host the servers in the cloud environment. The environment is rapidly growing, and the network does not have any more available IP addresses.

  Which of the following should the engineer do to accommodate additional servers in this environment?

  A. Create a VPC and peer the networks.

  B. Implement dynamic routing.

  C. Enable DHCP on the networks.

  D. Obtain a new IPAM subscription.

  Correct Answer: A

  Creating a VPC (Virtual Private Cloud) and peering the networks is the best option to accommodate additional servers in a public cloud environment that has run out of IP addresses. A VPC is a logically isolated section of a cloud provider's network that allows customers to launch and configure their own virtual network resources. Peering is a process of connecting two VPCs together so that they can communicate with each other as if they were in the same network.

• Question 280:

  A cloud administrator would like to deploy a cloud solution to its provider using automation techniques. Which of the following must be used? (Choose two.)

  A. Auto-scaling

  B. Tagging

  C. Playbook

  D. Templates

  E. Containers

  F. Serverless

  Correct Answer: CD

  Playbook and templates are two things that must be used to deploy a cloud solution to its provider using automation techniques. A playbook is a file or script that defines a set of tasks or actions to be executed on one or more cloud resources or systems. A playbook can automate and standardize the deployment and configuration of cloud solutions using tools such as Ansible, Chef, Puppet, etc. A template is a preconfigured image or blueprint of a cloud resource or system that contains an OS, applications, settings, etc., that can be used to create new resources or systems quickly and consistently. A template can simplify and speed up the deployment of cloud solutions using tools such as AWS CloudFormation, Azure Resource Manager, Google Cloud Deployment Manager, etc.
