Lesson 7: Managing Cloud Migrations and Troubleshooting Cloud Deployments Flashcards
An organization has configured a VPC (Virtual Private Cloud) but is often unable to access it due to repeated CSP (Cloud Service Provider) outages. The administrator checks the VPC downtime against the Service Level Agreement (SLA) and verifies the downtime is over the acceptable limits. What kind of issue does this represent?
A.Network connectivity
B.Performance
C.Instance configuration
D.Vendor-related
D.Vendor-related
When a CSP does not meet the standards established in the Service Level Agreement, this represents a vendor-related issue. If the vendor does not meet the SLA, they will often provide credits back to the customer.
An administrator is evaluating the infrastructure and services provided by an organization’s datacenter for a P2V migration. What reasons might the administrator be doing this? (Select all that apply.)
A.The administrator is preparing the organization to move from the cloud to an on-premises solution.
B.The administrator is preparing the organization to move from a virtualized solution to the cloud.
C.The administrator is preparing the organization to move from on-premises to a cloud solution.
D.The administrator is preparing the organization to move from on-premises to a virtualized solution.
C.The administrator is preparing the organization to move from on-premises to a cloud solution.
D.The administrator is preparing the organization to move from on-premises to a virtualized solution.
A Physical to Virtual (P2V) migration involves moving an organization from an on-premises or physical solution to a virtual or cloud solution.
A P2V migration can also involve moving an organization from an on-premises or physical solution to a virtualized solution for on-premises management.
A cloud architect has a migration contract for a company who wants to keep the migration fast and simple. Which type of migration would work best for the company?
A.Rehosting
B.Replatforming
C.Refactoring
D.Retaining
A.Rehosting
The rehosting cloud migration strategy is typically the fastest and easiest migration. The software involved is cloud ready, meaning that it can take advantage of cloud computing benefits; it can run in a virtualized environment and tolerate network connectivity.
A cloud administrator is troubleshooting insufficient capacity and performance degradation. Which of the following troubleshooting steps should be part of the process? (Select all that apply.)
A.Check oversubscription of computing resources
B.Check if correct templates are used to create instances
C.Check if cloud instance tags are accurate
D.Check load balancer type and configuration
A.Check oversubscription of computing resources
B.Check if correct templates are used to create instances
Oversubscription of computing resources is something to check for insufficient capacity and performance degradation. Other things to check for are Network latency, auto-scaling configurations correct, compute configurations (vCPU, threads, memory), storage capacity and type, and container configurations.
Checking if correct templates are used to create instances is also something to check for insufficient capacity and performance degradation.
An administrator is evaluating an application for migration to the cloud and determines that before migrating the application, the organization must first send it back to the developers to remove hard-coded IP addresses and make other minor modifications. What cloud migration type does this represent?
A.Rehost
B.Replatform
C.Refactor
D.Retain
B.Replatform
An application that requires some modification before it migrates to the cloud represents a replatform or “lift, tinker, and shift” cloud migration type.
Which of the following scenarios represents a cloud-to-cloud migration? (Select all that apply.)
A.An administrator migrating an organization’s data from a VPC to a community cloud.
B.An administrator migrating an organization’s data from a CSP to an on-premises solution.
C.An administrator migrating an organization’s data from a CSP to a VPC.
D.An administrator migrating an organization’s data from GCP to AWS.
A.An administrator migrating an organization’s data from a VPC to a community cloud.
C.An administrator migrating an organization’s data from a CSP to a VPC.
D.An administrator migrating an organization’s data from GCP to AWS.
A VPC (Virtual Private Cloud) and a community cloud are both cloud-based services. An administrator migrating an organization’s data from a VPC (Virtual Private Cloud) to a community cloud is performing a cloud-to-cloud migration.
A CSP (Cloud Service Provider) and a VPC are both cloud-based services. An administrator migrating an organization’s data from a CSP to a VPC is performing a cloud-to-cloud migration.
GCP (Google Cloud Platform) and AWS (Amazon Web Services) are both cloud-based services. An administrator migrating an organization’s data from GCP to AWS is performing a cloud-to-cloud migration.
A colleague reported that the Virtual Machine migration to the cloud failed immediately after starting the process. A pop-up window showed a failed connectivity status. What can the team check on to troubleshoot this issue? (Select all that apply.)
A.Check network latency
B.Check ISP
C.Check logs
D.Check storage capacity
B.Check ISP
C.Check logs
Check the Internet Service Provider (ISP) because network connectivity failed. Internet access to a Cloud Service Provider (CSP) is required.
Check logs to determine other issues related to networking. Review the logs at the source environment since there is no connection to the destination or CSP.
An administrator manually configured four new VM (Virtual Machine) instances in the public cloud. Three of the VM instances work, but the administrator is unable to connect to the fourth instance from the on-premises network. What might the administrator have done to cause the connection to the fourth instance to fail? (Select all that apply.)
A.The administrator used a misconfigured VM template.
B.The administrator did not follow the correct procedures.
C.The administrator applied inaccurate instance tags.
D.The administrator used a misconfigured script.
B.The administrator did not follow the correct procedures.
C.The administrator applied inaccurate instance tags.
Since the administrator manually configured the instances, it is likely the correct procedures were not followed for configuring the fourth instance.
Since the administrator manually configured the instances, it is likely the instance tags were not applied to the fourth instance correctly, if at all.
An administrator is investigating why an application within a container isn’t operational. Which of the following options is NOT a likely cause that the administrator needs to investigate?
A.An oversubscription of compute resources
B.Container images are valid
C.Container engine is running
D.Container hosting the app is running
A.An oversubscription of compute resources
An oversubscription of compute resources may cause issues with cloud performance degradation but will not cause an application not to run in a container.
The performance of an organization’s cloud network is degrading, and the administrator is troubleshooting possible causes. What are some items the administrator should investigate? (Select all that apply.)
A.Auto-scaling configurations
B.Storage capacity and type
C.Automation tools
D.Network bandwidth
A.Auto-scaling configurations
B.Storage capacity and type
D.Network bandwidth
The administrator should investigate the auto-scaling configurations to ensure the configurations increase resources properly during high volume usage times.
The administrator should investigate the storage capacity and type to ensure that there is enough balance between the solid state disk (SSD) and hard disk drive (HDD) to manage cache, fast writes, and reads.
The administrator should investigate the network bandwidth to ensure that there is enough capacity to handle the traffic generated by the network devices.
An organization is evaluating options for migrating millions of medical records to a community cloud. The organization needs to migrate the records as quickly as possible and without any downtime. What are the best solutions for migrating the data? (Select all that apply.)
A.The organization should migrate the data using an automated file transfer command like curl.
B.The organization should migrate the data using a CSP’s proprietary solution that avoids the public Internet.
C.The organization should migrate the data using a storage transfer service.
D.The organization should migrate the data using peering over the public Internet.
B.The organization should migrate the data using a CSP’s proprietary solution that avoids the public Internet.
C.The organization should migrate the data using a storage transfer service.
Migrating data using a Content Service Provider’s (CSPs) proprietary solution that avoids the public Internet is a good choice. As medical records are sensitive information, the organization must avoid transferring that data over the public Internet.
Migrating data using a storage transfer service is a good choice. A storage transfer service can migrate large amounts of encrypted data.
An organization needs to migrate a number of large databases from an Amazon Web Services (AWS) cloud to an Azure cloud. The databases use tables to store the data and keys to link the data information. What solution will the organization use to migrate the data?
A.Direct
B.Cross-service
C.Relational
D.Non-relational
A.Direct
The organization will use a direct migration, which migrates databases with the same database design between two Cloud Service Providers (CSPs), to migrate the relational databases from the AWS cloud to the Azure cloud.
Users are reporting that they are unable to connect with the organization’s cloud resources. What items should the administrator check? (Select all that apply.)
A.Is the CSP experiencing a network outage?
B.Is there a VM instance misconfiguration?
C.Are the users’ applications consuming too much bandwidth?
D.Is the organization’s ISP experiencing a network outage?
A.Is the CSP experiencing a network outage?
D.Is the organization’s ISP experiencing a network outage?
The administrator should check with the CSP (Cloud Service Provider). If the CSP is having an outage, then users will not be able to connect with cloud resources.
The administrator should check with the organization’s ISP (Internet Service Provider). If the ISP is having an outage, then users will not be able to connect with cloud resources
