• Question 31:

  When designing for large addressing space in HCI nodes, what operations(s) negatively impacts cost of performance?

  A. First write

  B. Page-in and page-out

  C. Random write

  D. Sequential read

  Correct Answer: C

• Question 32:

  A cloud architect is evaluating an organization's need for encryption. Which type of encryption eliminates the requirement for key management?

  A. File system-based

  B. Virtual disk

  C. Embedded

  D. File-based

  Correct Answer: B

  The most convenient form of encryption is disk/volume encryption. If you have any data on an existing Virtual Machine (VM), you can easily add an encrypted disk or volume. Then, when you unmount the encrypted volume (or power off the

  server), as long as you don't store the encryption key on the server, your data is safe.

  The drawback with this type of encryption however is that if your server gets compromised somehow, there is a possibility that the attacker could capture your passphrase/key (and/or data) the next time you mount the disk image.

• Question 33:

  Which design consideration applies to object storage?

  A. Multi-tenancy is supported through file and directory permissions

  B. It is best suited for high performance and low latency applications

  C. A RAID controller on the host computer handles redundancy

  An organization uses Microsoft Active Directory (AD) for service authentication in their private cloud.

  They want to use the same authentication source for services in the public cloud. External employees access services in both clouds and need to authenticate with AD. The organization wants to minimize and secure network traffic. Which

  solution will address these requirements?

  A. External users connect with IPsec VPN Place AD controllers in the private cloud only

  B. Configure perimeter firewalls to allow AD traffic Place AD controllers in the private and public clouds

  C. Connect the two clouds through IPsec VPN Place AD controllers in the private cloud only

  primary requirement is to provide for automated site recovery.

  What is a key consideration for automating the setup, failover, and recovery of services at the remote site?

  A. When implementing automated site recovery, you must have automated orchestration of site failback processes

  B. The number of storage volumes in the DR site must be identical in number and size to the primary site.

  C. The recovery site must have sufficient available capacity to host workloads after a disaster at the primary site.

  D. The DR site must contain the same vendor hardware as the primary site.
