vCenter reports a connectivity problem with a ESXi 5.x host that is not a member of a cluster. An administrator attempts to connect directly to the host using the vSphere Client but fails with the message "An unknown connection error occurred." Virtual machines running on the host appear to be running and report no problem. What two methods would likely resolve the issue without affecting the virtual machines? (Choose two.)

Click the Exhibit button. An administrator is creating a vApp for a multi-tiered web application. The vApp has been configured as shown in the exhibit. Testing of the vApp indicates that attempts to communicate with the web server on Dev_Web_01 fail. The developer wants to be sure the database server OS is completely started before the other servers power on. The developer also wants to minimize recovery time. What changes to the vApp configuration will correct the issues?

ACME Anvil Incorporated has several departments which each have unique resource requirements in their environment: 1. The Manufacturing department has ten production virtual machines. 2. The Development department has two test/dev virtual machines. 3. The Manufacturing virtual machines have only CPU reservations. 4. No Development virtual machine should be able to use more resources than any Manufacturing virtual machine requests. 5. Manufacturing department virtual machines must always be able to power on. Resource Pools will be used to address these requirements. When creating the "Manufacturing" and "Development" pools, which settings should be part of the configuration to meet the stated requirements? (Choose two.)
