NO.1 Click the Exhibit button.
An administrator has deployed a two-node cluster with HA and DRS enabled. DRS has been
configured for fully automated mode. The management and vMotion interfaces have been
configured on separate physical networks. Initial DRS testing on this cluster reveals that virtual
machines are not being migrated despite great disparity in resource use between the ESX hosts in the
cluster. The exhibit shows the error and the network configuration for one of the hosts.
Which task would successfully resolve this problem?
A. Add a vmnic to the VMkernel port
B. Configure the DRS Migration Threshold to Aggressive
C. Connect the network cable to the correct physical network
D. Migrate vitual machines manually using vMotion
Answer: C

Explanation:
Make sure that the network cable is connected to the correct physical network.

NO.2 What are two methods of maximizing VMFS performance for virtual machines across all the
hosts in a cluster? (Choose two.)
A. Use disk shares to prioritize virtual machine disk I/O
B. Enable Storage I/O control
C. Enable Storage DRS with I/O load balancing
D. Enable Host Cache using local SSD drives
Answer: B,C

Explanation:
To maximize VMFS performance of virtual machines, you can enable Storage I/O control and storage
DRS with I/O load balancing. Reference: http://www.vmware.com/files/pdf/techpaper/VMW-

NO.3 A database administrator has reported periodic poor performance on a particular virtual
machine. The virtual machine administrator has noticed a significant drop in performance when
utilized memory exceeds 1GB.
What does this indicate and what could be checked next?
A. The application problems are definitely due to a non-memory-related problem. CPU affinity
settings should be checked for this virtual machine.
B. The application problems are definitely due to a non-memory-related problem. CPU utilization
should be checked next, using Windows Task Manager.
C. The virtual machine might not have physical memory available. Compression and swap activity on
the ESXi host should be checked next.
D. The virtual machine might not have physical memory available. Ensure the memory limit on the
VM is set to 0 MB.
Answer: C

certification VMware   VCI510 examen   VCI510
Explanation:
If the performance degrades when the memory exceeds the allocated value, the virtual machine
might not have physical memory available. Check compression and swap activity on ESXi host to see
where the additional memory is going.

NO.4 What failure will beacon probing identify in vSphere networking?
A. An improper VLAN configuration on a physical switch port
B. A disconnected network cable
C. A VMkernel IP mismatch affecting vMotion or HA traffic
D. Jumbo frames improperly configured on an iSCSI target
Answer: A

(see beacon probing)

NO.5 Which two statements are true regarding vSphere standard switches? (Choose two.)
A. Beaconing requires at least three uplinks to be considered useful.
B. Virtual machines on different vSwitches require the vSwitches to share an uplink to communicate.
C. vSphere virtual switches require at least one uplink adapter.
D. Setting the number of ports to the maximum on a vSwitch will exhaust the total ports on a host.
Answer: A,D
