An administrator is tasked with setting up Kerberos authentication only for the vSAN File services.
Which version of Kerberos must be selected if the NFS version is v4.1?
- A. krb5i
- B. krb5
- C. krb4
- D. krb5p
Answer: B
Explanation:
Support of Kerberos authentication helps prevent access of NFS clients through other, more vulnerable methods such as auth_sys. vSAN supports all 3 Kerberos authentication modes, KRB5, KRB5I and KRB5P.
* KRB5, which limits its role to secure authentication. (Only on NFSv4.1)
* KRB5I includes security authentication + checksum.
* KRB5P includes secure authentication + checksum + encryption.

- Reduce the impact of a disk failure on a vSAN capacity node.
- Reduce the need for a rebuild upon a disk failure.
- Achieve the best performance for application workloads.
- Leverage the amount of available vSAN space efficiently.
The customer has already purchased all hardware and therefore the vSAN 7.0 U1 cluster is constrained to one Disk Group per node.
Which vSAN cluster option should the architect enable to meet these requirements?
- A. Data-at-rest encryption
- B. Deduplication only
- C. Compression only
- D. Deduplication and Compression
Answer: C
NEW QUESTION # 35
Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to at least double the usable capacity in their all-flash vSAN cluster. The vSAN cluster is deployed into a co-located datacenter that is owned by a third-party hosting company. The hosting company charges a fixed monthly cost for rack space and power consumption. The service owner has been given a limited budget for additional hardware purchases, but not for on-going co-location costs.
The current vSAN cluster has the following configuration:
* 10 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM
* 1 Disk Group per vSAN node
- 1 x 400 GB
- 4 x 1.8 TB
* De-duplication and Compression is enabled.
* vSAN Capacity is currently:
- Total: 72 TB
- Usable: ~40 TB (FTT1/RAID1) and ~60 TB (FTT1/RAID5).
As a result of any action taken, the service owner would like to ensure that overall availability of the vSAN cluster is increased.
Which two recommendations meet the requirement to increase capacity while maintaining service availability? (Choose two.)
- A. Create a new Disk Group, and claim the newly installed cache and capacity SSD drives for each node.
- B. Install an additional 3 x 1.8 TB SSDs per vSAN node.
- C. Install an additional 400 GB SSD and 4 x 1.8 TB SSDs per vSAN node.
- D. Update the existing Disk Group, and claim the newly installed drives for each node.
- E. Replace existing SSDs with an 800 GB SSD and 4 x 3.8 TB SSDs per vSAN node.

NEW QUESTION # 36
In a stretched vSAN cluster, how is Read Locality established after fail over to the secondary site?
- A. 100% of the reads comes from vSAN hosts on the local site
- B. 50% of the reads comes from vSAN hosts on the remote site
- C. 100% of the reads comes from vSAN hosts on the remote site
- D. 50% of the reads comes from vSAN hosts on the local site
Answer: C
Explanation:
In the event of a failure or maintenance event, the virtual machine is restarted on the remote site. The 100% rule continues in the event of a failure. This means that the virtual machine will now read from the replica on the site to which it has failed over. One consideration is that there is no cached data on this site, so cache will need to warm for the virtual machine to achieve its previous levels of performance.

NEW QUESTION # 45
After a vSAN Witness Appliance network configuration, the vSAN administrator notices that vSAN traffic flows from vmk0 (Management Traffic) rather than vmk1 (vSAN Traffic).
Which step should be taken to resolve this issue?
- A. Configure vmk0 with IP address on the same range as that of vmk1.
- B. Tag the vmk0 for vSAN traffic.
- C. Tag the vmk1 for Witness traffic.
- D. Configure vmk1 with IP address on the different network than that of vmk0.
Answer: D
Explanation:
The vmk1 interface cannot be configured with an IP address on the same range as that of vmk0. This is because Management traffic and vSAN traffic use the default TCP/IP stack. If both vmk0 and vmk1 are configured on the same range, a multihoming condition will occur and vSAN traffic will flow from vmk0, rather than vmk1.

NEW QUESTION # 50
An administrator managing a vSAN cluster of six-nodes with policy FTT-2/RAID-6 decided to put one of the nodes in maintenance mode using the "Full-data migration" option.
What will happen after this action is taken?
- A. The system will prompt to add an additional host to the cluster in order to preserve the policy compliance.
- B. The host will enter in maintenance mode and only data with no redundancy will remain accessible.
- C. The host will enter into maintenance mode if both components of a certain object are residing on that host, then one of the components will be moved to another available host.
- D. The host will enter in maintenance mode and the data will remain accessible until the host exits maintenance mode.
Answer: A
Explanation:
Let's take a look at a few unique scenarios with regard to maintenance mode. First, let's see what will happen if you have 6 hosts within your cluster, you have applied a policy containing FTT=2/RAID-6, and you want to place a host in maintenance mode using the 'Full data migration' option. This means all the data residing on the host will be evacuated to another host within the cluster. With this type of data configuration, the system will prompt you to add an additional host to the cluster in order to preserve the policy compliance. The policy will always require there must be two failures that can be tolerated, even during cluster reduction due to maintenance mode removing a host. Note that a minimum of six hosts is required to support a storage policy with RAID-6(FTT=2) erasure coding.
