• Question 204:

  Every night a datacenter takes snapshots of each VM and backs them up to a tape which is shipped off to a disaster recovery site once a week. Which of the following can mitigate a security breach if the tapes were to fall out of the shipping vehicle during transport?

  A. Transmission level encryption

  B. Transport layer encryption

  C. Hard drive encryption

  D. File level encryption

  Correct Answer: C

• Question 205:

  An administrator is implementing a private cloud that will be used as a test environment. To limit the number of guests per subnet to a maximum of 14, the administrator implemented a /20 network. Which of the following should the administrator use to assign the networks?

  A. DHCP

  B. Subnet

  C. VLAN

  D. Gateway

  Correct Answer: A

• Question 206:

  After an administrator deployed a private cloud a couple of years ago, users have started reporting that the network is getting slower. The administrator looks at the monitoring tools and notices that, even though supernetting was used to allow for 8,000 more VMs, the most utilized switch port in the datacenter is only using 40% of its total throughput speed. Which of the following is MOST likely the problem?

  A. The number of VMs using 1Pv4 is causing the network to crash.

  B. Each host only has two links to the network, and they are becoming saturated.

  C. The network only has 4Gbps HBAs when all cloud networks should be using 10Gbps.

  D. There are too many devices broadcasting on the subnet.

  Correct Answer: D

• Question 207:

  A company is migrating their physical servers to virtual. The administrator is tasked with migrating three servers:

  One application server with a dual-core 3.2GHz processor that reaches 50% CPU utilization at peak time.

  Two web servers, each with a dual-core 3.2GHz processor, both reaching 70% CPU utilization at peak time.

  Currently, the administrator only has two hosts available, so resources will need to be set for the new VMs. Each host has two 2.4GHz quad-core processors. One host is already near maximum capacity, and the second host is at 30% CPU utilization.

  Which of the following would be the BEST minimum CPU resources set on the second host for the new VMs?

  A. 1,600 MHz for the application server and 2,300 MHz for each web server.

  B. 3,300 MHz for the application server and 4,600 MHz for each web server.

  C. 3,300 MHz for the application server and 5,250 MHz for each web server.

  D. 5,250 MHz for the application server and 7,080 MHZ for each web server.

  Correct Answer: A

• Question 208:

  Which of the following techniques would be used to deliver SLA performance guarantees for a VM in a virtual environment? (Select two.)

  A. Licensing

  B. Mirroring

  C. Resource pooling

  D. Memory ballooning

  E. Reservations

  Correct Answer: BC

• Question 209:

  Which of the following is the BEST choice for a clustered host interconnect?

  A. Infiniband

  B. 1Gb Ethernet

  C. 10Gb Ethernet

  D. Fibre Channel

  Correct Answer: D

• Question 210:

  Fault tolerant design allows a host to overcome a single HBA failure through:

  A. clustering

  B. UTA pairing

  C. multipathing

  D. NIC teaming

  Correct Answer: A
