• Question 391:

  An application server, which uses a SaaS fax provider, is determined to cost too much money. An upgrade to the application allows for use of a physical fax card so the company only has to pay for a phone line. This is a production application; therefore, downtime must be minimized. Which of the following types of migration is MOST efficient in facilitating this application upgrade?

  A. Virtual-to-physical migration

  B. Storage migration

  C. Cloud migration

  D. Offline migration

  Correct Answer: A

• Question 392:

  A cloud deployment engineer is modifying versions of the existing template image to instantiate new VMs. The engineer accomplishes this through the cloud self-service portal. After the version is changed and a new VM is successfully started, it does not have any connectivity, and all ping tests to other VMs fail. Which of the following would be the BEST approach to solve the problem?

  A. Start the console session to the VM; check network static routes; test the ping to default gateway and next hop; and reconfigure the gateway IP.

  B. Delete the VM; create a new flavor; turn on network service; add the new image to the template manager; and reinstantiate the VM using this new image.

  C. Delete the VM; check the IP assignment and planning; modify configuration in the deployment template; and instantiate the VM again using the new template.

  D. Assign new IPs to the newly created VMs by changing and running the deployment template; and check the connectivity on the cloud self-service portal afterward.

  Correct Answer: D

• Question 393:

  A recent advertisement campaign has increased traffic to an e-commerce application that is hosted within a public cloud environment. Customers are reporting that it takes too long to load their pages and submit orders. A cloud administrator looks at the metrics from the environment and sees high utilization of the CPU and memory resources. The cloud provider offers several preconfigured sizes for server template: x-small, small, medium, large, x-large, and 2x-large.

  

  Given an expected increase in workload, which of the following is the BEST solution to improve application performance?

  A. Change the server template size for Inxpc003 to 2x-large.

  B. Provision additional Inxpc servers using the 2x-large template.

  C. Add memory to Inxpc002, Inxpc003, and Inxpc003.

  D. Change the role of Inxw001 from web to application.
