Lesson 11: Managing Cloud Performance Flashcards
Which of the following is NOT a compute resource that can affect performance on a network?
A.Applications
B.Memory
C.Storage
D.Power consumption
A.Applications
While application issues can cause performance problems on a network through misconfigurations or other issues, applications are not compute resources.
An administrator has configured backup jobs for new cloud instances. What methods can the administrator use to verify that the backup data is valid? (Select all that apply.)
A.Check the backup logs for errors and completion status.
B.Check the backup software status.
C.Perform a test restore of the data.
D.Review the backup retention policy.
A.Check the backup logs for errors and completion status.
C.Perform a test restore of the data.
Examining backup logs is an effective method for verifying the validity of backup data. Logs can provide information about backup start and completion times, errors encountered during the backup process, and the status of each backup job.
The administrator can verify the backups completed successfully by performing a test restore of the backups to ensure that data successfully restores.
A website in Asia that sells inexpensive electronics and clothing has become quite popular with teenagers in the United States. What can the cloud administrator configure to ensure that network latency doesn’t cause the website to load too slowly for users in the US?
A.CDN
B.SDN
C.NIC teaming
D.Higher bandwidth
A.CDN
The cloud administrator can ensure that Content Delivery Network (CDN) is enabled for the website. The CDN will cache the website in a region closer to the users and ensure that the users can access the website quickly.
A developer is experiencing memory issues with their application on cloud based servers. Which of the following steps would assist the developer in identifying and fixing the problem? (Select all that apply.)
A.Check for memory leaks
B.Check host operating system logs
C.Ensure appropriate storage tiers
D.Check network devices that slow communications
A.Check for memory leaks
B.Check host operating system logs
Checking for memory leaks is a step in troubleshooting application memory issues. Assuming a cloud-hosted application issue, ensuring the application is running, has network connectivity, and the user has permissions to use the resource are good places to start.
Checking host operating system (OS), container, and application logs are all important steps in troubleshooting application memory issues.
An on-premises cloud network usually has enough resources to handle all the online traffic for a busy department store. However, when the department store has special sales, the on-premises network becomes oversaturated with traffic. To mitigate this issue, the administrator configured the network to add virtual machines from a public cloud network as necessary. What type of right-sizing model does this represent?
A.Horizontal scaling
B.Vertical scaling
C.Cloud bursting
D.Auto-scaling
C.Cloud bursting
When an administrator configures an on-premises cloud to spill over into a public cloud to add more resources during times of high usage, this represents cloud bursting.
At which phase of the lifecycle roadmap would a cloud application serve as a reference for upcoming services to an organization?
A.Deployment phase
B.Maintenance phase
C.Deprecation phase
D.Development phase
D.Development phase
The development phases of the lifecycle roadmap include new systems or applications that will reference upcoming services. A beta version of this will remain in this phase.
An administrator is viewing the organization’s lifecycle roadmap. What kind of information will the administrator NOT see on the Gantt chart?
A.The status of deployments
B.Deployment budgeting
C.Deployment planning
D.Deployment personnel
D.Deployment personnel
The administrator will not see the deployment personnel on the lifecycle roadmap. The roadmap shows information about systems, budgeting, and planning, but not personnel.
An administrator is viewing the VM OS performance monitor on an instance and notices that the operating system has unusually low utilization. What does this indicate?
A.Too much storage
B.Too much memory
C.Not enough memory
D.Not enough storage
B.Too much memory
When the performance monitor reveals that the operating system has low utilization, it indicates that the instance has too much memory allocated to the system and could operate optimally with less.
A security engineer creates a storage location for historical file purposes. File access should be quick if files are ever needed. Which of the following storage solutions is most appropriate?
A.Standard
B.Standard infrequent
C.Intelligent tiering
D.Glacier
B.Standard infrequent
Standard infrequent is long term storage that is rarely accessed but must perform well when needed. Storage tiers are one way that cloud service providers (CSPs) help optimize storage intensive workloads.
An organization is upgrading all of its systems in the environment. When the upgrade is complete, the organization will switch from the upgraded environment to production, and later, upgrade all of the systems in the demoted environment. What kind of upgrade process does this represent?
A.Blue-green upgrade
B.Canary upgrade
C.Rolling upgrade
D.System upgrade
A.Blue-green upgrade
This process represents a blue-green upgrade where there are two identical environments. The organization updates the passive environment and makes it active, and then later updates the other environment.
An organization is currently testing a cloud solution that will allow developers to create their own development environments, transitioning away from the current on-premises approach where developers have to request the IT department to set up environments for them. What step of the change management process does the testing of this cloud solution represent?
A.Propose
B.Approve
C.Develop
D.Deploy
C.Develop
This scenario represents the develop phase of the change management process. This is where the organization develops and tests new applications, services, or other features in preparation for deployment.
Which of the following would NOT be an example of appropriate consumer responsibility when patching cloud resources running on an infrastructure as a service (IaaS) solution?
A.Patch virtual machine (VM) OS.
B.Patch web service in VM.
C.Patch container software.
D.Patch virtual host hypervisor.
D.Patch virtual host hypervisor
A cloud service provider (CSP) provides hardware infrastructure for an infrastructure as a service (IaaS) solution and is responsible for all layers starting from the virtual hosts and below. The CSP manages hardware failures, firmware updates, and hypervisor patches, for example.
What process improvement benefits would an organization realize by allowing developers to create their own development environments from templates in the cloud, rather than having to wait for on-premises administrators to create the environments for them? (Select all that apply.)
A.Streamlined processes for greater efficiency
B.Faster deployments
C.Less infrastructure investment
D.Greater collaboration opportunities
A.Streamlined processes for greater efficiency
B.Faster deployments
By allowing developers to create their own development environments from templates in the cloud, the organization would streamline processes for greater efficiency.
By allowing developers to create their own development environments from templates in the cloud, the organization would achieve much faster deployments of the development environments.
An administrator is receiving complaints from users that the network is too slow. What steps should the cloud administrator take to reduce network latency? (Select all that apply.)
A.Eliminate replication
B.Implement segmentation
C.Implement an edge network
D.Implement an NPB
B.Implement segmentation
C.Implement an edge network
D.Implement an NPB
The administrator can implement segmentation to separate network traffic and keep traffic from clogging up other parts of the network.
The administrator can implement an edge network, or content delivery network, to place the systems and data closer to the users who are using it.
The administrator should implement a Network Packet Broker (NPB) to monitor network traffic and send it to the appropriate tool to eliminate the strain of each tool monitoring network traffic individually.
A cloud administrator needs an overall view of the cloud network’s service availability, instance and network performance, capacity planning, and incident management. What can the administrator configure to get a centralized view of all the information?
A.Tagging
B.Dashboards
C.Showbacks
D.Availability and health
B.Dashboards
The administrator can configure dashboards to see an overall view of the cloud network’s service availability, instance and network performance, capacity planning, and incident management, and more.
