Correct Answer: B 🗳️
A company has to implement a test/dev environment infrastructure as quickly as possible. The company does not have weeks or months to accomplish this. They also have limited resources available.
Considering their timeline, what type of infrastructure would the company most likely have to choose?
- A. An internal, virtualized environment with shared resources
- B. An internal, virtualized data center with automation
- C. An offering from a cloud service provider
- D. A traditional data center
Correct Answer: C 🗳️
You are meeting with the CIO to discuss your VDC design. They the amount of capital that is being invested in iSCSI adapters. They state that, because of the number of adapters required, it is more cost-effective to purchase 10 Gigabit Ethernet NICs and use the integrated hypervisor software stack.
How should you justify the increased cost of the iSCSI Adapters?
- A. Using NICs and the software stack will increase CPU load on each hypervisor, requiring more hypervisors to deliver the same performance levels. This will result in additional hardware and licensing costs.
- B. iSCSI adapters can encrypt iSCSI frames, preventing unauthorized access to the data. The hypervisor software stack cannot encrypt iSCSI frames, leaving the data vulnerable.
- C. Using NICs and the software stack will require additional NICs for each hypervisor to deliver the same throughput. To obtain the additional PCIe slots for the NICs, larger form-factor servers will be required, increasing hardware costs.
- D. iSCSI adapters can use Jumbo Frames, providing improved performance for storage traffic. The hypervisor software stack cannot use Jumbo Frames, resulting in poorer performance.
Correct Answer: A 🗳️
Refer to the exhibit.
You are expanding the compute layer of a VDC, and need to add more access layer switches to provide connectivity to the hypervisors. However, there are no available ports on the two aggregation layer switches to accommodate the uplink connections from the new access layer switches, and all uplinks are active and operating at 95% of capacity.
Your design must satisfy all of the following requirements:
-Expand the access layer
-
Maintain the same configuration as the existing environment
-
Maintain the performance of the existing environment
The CIO has authorized you to purchase additional aggregation layer switches if needed.
What should you recommend?
- A. Purchase one new aggregation layer switch.
Aggregate it with the existing switches.
Redistribute all access layer switches across all aggregation layer switches. - B. Purchase two new aggregation layer switches.
Connect the new access layer switches to them. - C. Purchase one new aggregation layer switch.
Connect the new access layer switches to it. - D. Purchase two new aggregation layer switches.
Aggregate them into a virtual switch.
Connect the new access layer switches to them.
Correct Answer: D 🗳️
