CD
Explanation:
Problem
A datastore in a datastore cluster cannot either maintenance mode. The Entering Maintenance Mode status remains at 1%.
Cause
One or more disks on the datastore cannot be migrated with Storage vMotion. This condition can occur in the following instances.
Storage DRS is disabled on the disk
Storage DRS rules prevent Storage DRS from making migration recommendations for the disk.

Which two statements correctly describe VM-Host affinity rules? (Choose two.)
- A . When there is more than one VM-Host affinity rule in a vSphere DRS cluster, the rules are applied equally.
- B . After creating a VM-Host affinity rule, its ability to function in relation to other rules is predetermined.
- C . When there is more than one VM-Host affinity rule in a vSphere DRS cluster, the rules will be ranked.
- D . After creating a VM-Host affinity rule, its ability to function in relation to other rules is not checked.
AD
Explanation:
If you create more than one VM-Host affinity rule, the rules are not ranked, but are applied equally. Be aware that this has implications for how the rules interact. For example, a virtual machine that belongs to two DRS groups, each of which belongs to a different required rule, can run only on hosts that belong to both of the host DRS groups represented in the rules. When you create a VM-Host affinity rule, its ability to function in relation to other rules is not checked. So it is possible for you to create a rule that contacts with the other rules you are using. When two VM-Host affinity rules conflict, the older one takes precedence and the newer rule is disabled. DRS only tries to satisfy enabled rules and disabled rules are ignored.

How can failback of a recovered virtual machine in vSphere Replication be performed?
- A . No action required, because failback is automatically performed to the source site.
- B . Configure a new replication in the reverse direction at the target site.
- C . Disable or Stop the virtual machine replication on the source site.
- D . Power off and unregister the virtual machine on the target site.
B
Explanation:
Failback of Virtual Machines in vSphere Replication
Failback of virtual machines is a manual task in a vSphere Replication. After performing a successful recovery from the primary site to the secondary site, you can perform failback. You manually configure a new replication in the reverse direction, that is, from the secondary site to the primary site. The disks of the primary site are used as replication seeds, so that vSphere Replication only synchronizes the changes made to the .vmdk files. Before you configure the reverse replication, you must manually unregister the virtual machine from the inventory on the primary site.

BDE
Explanation:
You might want fewer, larger LUNs for the following reasons:
– More flexibility to create virtual machines without asking the storage administrator for more space.
– More flexibility for resizing virtual disks, doing snapshots, and so on.
– Fewer VMFS datastores to manage.

A vSphere HA cluster with four hosts has admission control configured to tolerate one host failure.
Which statement is true if a fifth host is added?
- A . CPU and Memory capacity will be set to 50%.
- B . CPU and Memory capacity will be set to 30%.
- C . CPU and Memory capacity will be set to 25%.
- D . CPU and Memory capacity will be set to 20%.
D
Explanation:
Select the Percentage of Cluster Resources Reserved admission control policy. This policy offers the most flexibility in terms of host and virtual machine sizing. When configuring this policy, choose a percentage for CPU and memory that reflects the number of host failures you want to support. For example, if you want vSphere HA to set aside resources for two host failures and have ten hosts of equal capacity in the cluster, then specify 20%

An administrator finds that the Microsoft Exchange virtual machines are exhibiting network latency.
What two in-guest changes can help decrease latency? (Choose two.)
- A . LRO
- B . TSO
- C . SR-IOV
- D . PVRDMA
AB
Explanation:
Using TSO and LRO on physical and virtual machine NICs improves the performance of ESX/ESXi hosts by reducing the CPU overhead for TCP/IP network operations. The host uses more CPU cycles to run applications.
If TSO is enabled on the transmission path, the NIC divides larger data chunks into TCP segments. If TSO is disabled, the CPU performs segmentation for TCP/IP.
TSO is referred to as LSO (Large Segment Offload or Large Send Offload) in the latest VMXNET3 driver attributes. LRO reassembles incoming network packets into larger buffers and transfers the resulting larger but fewer packets to the network stack of the host or virtual machine. The CPU has to process fewer packets than when LRO is disabled, which reduces its utilization for networking.

What counter should an administrator check to determine if a virtual machine is ballooning?
- A . swapinRate
- B . vmmemctltarget
- C . swapped
- D . vmmemctl
D
Explanation:
Memory Ballooning is the memory reclamation technique used by hypervisor to reclaim the memory back from the virtual machine. When ESXi host running low on physical memory, It uses ballooning driver (vmmemctl.sys) to determine the how much memory from virtual machines can be get back to prevent the hypervisor swapping.

Which two statements are true for NFS v4.1 firewall behavior? (Choose two.)
- A . It closes port 2049.
- B . It sets allowed. All flag to TRUE.
- C . It sets allowed. All flag to FALSE.
- D . It opens port 2049.
BD
Explanation:
NFS v4.1 Firewall Behavior
When you mount the first NFS v4.1 datastore, ESXI enables the nfs41client rule set and sets its allowed All flag to TRUE. This action opens port 2049 for all IP address. Unmounting an NFS v4.1 datastore does not affect the firewall state. That is, the first NFS v4.1 mount opens port 2049 and that port remains enabled unless you close it explicitly.

A Telco customer is implementing NFV using vSphere as the virtualization platform.
Which feature can help achieve a high packet rate with lower CPU consumption?
- A . Network I/O Control
- B . SplitRX
- C . ERSPAN
- D . LACP
B
Explanation:
SplitRx Mode
SplitRx mode uses multiple physical CPUs to process network packets received in a single network queue. This feature can significantly improve network performance for certain workloads. These workloads include:
Multiple virtual machines on one ESXi host all receiving multicast traffic from the same source. (SplitRx mode will typically improve throughput and CPU efficiency for these workloads.)
Traffic via the vNetwork Appliance (DVFilter) API between two virtual machines on the same ESXi host. (SplitRx mode will typically improve throughput and maximum packet rates for these workloads.)
In vSphere 5.1 and later this feature is automatically enabled for a VMXNET3 virtual network adapter (The only adapter type on which it is supported) when ESXi detects that a single network queue on a physical NIC is both (a) heavily utilized and (b) getting more that 10,000 broadcast/multicast packets per second.

An administrator is trying to vMotion a VM from his datacenter to a recovery site.
Which is the maximum allowed RTT (Round-Trip Time) latency between source and destination host?
- A . 100 milliseconds
- B . 150 milliseconds
- C . 15 milliseconds
- D . 10 milliseconds
B
Explanation:
Round-Trip Time for Long-Distance vMotion Migration If you have the proper license applied to your environment, you can perform reliable migrations between hosts that are separated by high network round-trip latency times. The maximum supported network round-trip time for vMotion migrations is 150 milliseconds. This round-trip time lets you migrate virtual machines to another geographical location at a longer distance.

Which is required for configuring iSCSI Software Adapter network port binding?
- A . VMkernel of the iSCSI traffic must be load balanced using Route based on IP Hash algorithm.
- B . VMkernel of the iSCSI traffic must be load balanced using Route based on Source Virtual Port ID algorithm.
- C . VMkernel of the iSCSI traffic must be load balanced using Route based on Source MAC Hash algorithm.
- D . VMkernel of the iSCSI traffic must be bound to only one active network adapter.
D
Explanation:
(…) ensure each vmkernel port has a unique active adapter.
