287 Ed is the overnight manager of his company's datacenter, and he is responsible for both private and public resources in the company's hybrid cloud. Due to a new TV commercial shown that night, the company's website experiences a massive upsurge in traffic. The web server farm on the private cloud is being overwhelmed, so Ed configures some virtual machines in the public cloud to take up the slack. Which of the following is a common term for what Ed has done?Cloud bustingCloud burstingCloud splittingCloud migrating

288 Microsoft's Outlook.comemail service is an example of which of the following cloud service models?IaaSPaaSSaaSDaaSNone of the above

289 Which of the following statements about cloud delivery models is true?A public cloud is inherently insecure because anyone can access it.A private cloud consists of hardware that is all located in a single datacenter.A hybrid cloud enables administrators to migrate services between public and private resources.Public, private, and hybrid clouds all utilize the same hardware resources.

290 Ed has just created a new Windows application for his company, and he wants to deploy it in the public cloud. He is looking for a provider that will furnish his company with a fully installed and configured Windows server on which he can install and run his application. Which of the following service models is he seeking to use?IaaSPaaSSaaSDaaSNone of the above

291 Which of the following are valid advantages or disadvantages of multitenancy in a public cloud datacenter? (Choose all that apply.)Multitenancy presents a potential security risk because other tenants are utilizing the same hardware.Multitenancy reduces the cost of utilities and other overhead.Multitenancy introduces the possibility of competition for bandwidth with other tenants.Multitenancy separates tenants by assigning each one its own virtual machine.

292 Which of the following is not one of the advantages of Infrastructure as Code (IaC) deployment for cloud-based virtual machines?IaC provides rapid deployment of virtual machine configurations.IaC provides consistency in virtual machine configurations.IaC provides cost savings by automating the virtual machine configuration process.IaC provides increased security by encrypting the virtual machine configurationIaC provides elasticity and scalability by simplifying the virtual machine deployment process.

293 Ralph is designing a hybrid deployment for a corporate client that will require a connection between the client's private network and a public cloud provider. The client is concerned about this connection becoming a speed bottleneck at times of heavy user traffic. Which of the following options can Ralph offer the client that will best address this potential problem?Use a different ISP for the cloud connection.Use a VPN for the cloud connection.Use a cloud direct connection for the hybrid link.Use a leased line connection to the ISP

4 Ralph has been hired by a company to redesign its Local Area Network (LAN). Right now, it has a single 100 Mbps Ethernet LAN with 40 users and 2 shared servers, all connected through 3 hubs. The users on the network must be able to share files with one another and also access the shared servers. The users are complaining that the network is too slow. Management states that cost is a factor that must be considered. Which of the following upgrade scenarios should Ralph recommend in this situation?Split the network into smaller segments with dedicated hubs as opposed to shared hubs.Split the network into two routed LANs with 20 users each.Replace the hubs with switches to define separate collision domains and filter unnecessary traffic from each segment.Replace the hubs with a layer 3 switch and define two Virtual LANs (VLANs) with 20 users each.

5 Which of the following devices can split a single network into two collision domains while maintaining a single broadcast domain?HubBridgeSwitchRouterRepeater

6 Which two of the following functions is the multifunction device on a home or small office network known as a broadband router least likely to provide? (Choose two.)Wireless Access Point (WAP)SwitchProxy serverDHCP serverVPN headend
