When considering incorporating redundancy into design, which of the following should be considered?
Answer(s): D
The recovery time objective (RTO)--also known as the return to operation--is the amount of time it takes to restore a service after a failure has taken place. The recovery point objective (RPO) is the point in time to which the system needs to be restored following a failure. In some cases a business may be interested in functionality and just assume items such as redundancy. The infrastructure qualities help consider aspects considered as good design.
Which of the following factors should influence the decision of whether to virtualize an application? (Choose three)
Answer(s): A,B,C
Good design should meet the project requirements and consider the properties of assumed platform design. Protecting data requires that a system be available and manageable, that it have good performance, and that it be easy to recover and be secure.
Which of the following describes the anticipated time until a solution component may fail?
Answer(s): C
The recovery time objective (RTO)--also known as the return to operation--is the amount of time it takes to restore a service after a failure has taken place. The recovery point objective (RPO) is the point in time to which the system needs to be restored following a failure. The MTBF is the amount of time a component is predicted to fail and can be used with operational management or design concepts.
A well-thought-out request for change document contains . (Choose three)
An implementation plan gives all members of a project team a level of understanding of the technical approach of a project, the number of phases, major tasks in each phase, and the correct order for completing the tasks.
You are a VMware platform designer at a large service provider reviewing a network design. Two of the requirements are as follows:R001: All traffic must be encrypted or separated. R002: All components must be fault tolerant. The current design involves software-based iSCSI storage with teamed 1 GB network cards for the storage network. The iSCSI network has a uniqiue vLAN and network ID. The design ensures that a different password is used for each LUN.The current design meets both requirements.
Answer(s): A
By using NIC teaming, iSCSI is configured in a fault-tolerant manner. However, it is not encrypted but is separated; therefore R001 and R002 are satisfied.
