QUESTION 241
vCenter reports a connectivity problem with a ESXi 5.x host that is not a member of a cluster. An administrator attempts to connect directly to the host using the vSphere Client but fails with the message “An unknown connection error occurred.” Virtual machines running on the host appear to be running and report no problem.
What two methods would likely resolve the issue without affecting the virtual machines? (Choose two.)
A. Enter the service mgmt-vmware restart command from either SSH or local CLI
B. Select Restart Management Agents in the Direct Console User Interface (DCUI)
C. Select Reboot Host in the Direct Console User Interface (DCUI)
D. Enter the services.sh restart command from either SSH or the local CLI

QUESTION 242
An administrator notices that log files kept on an ESXi 5.x host are being rotated very quickly, inhibiting the troubleshooting of an issue.
Which two configuration changes will resolve the issue? (Choose two.)
A. Configure syslog to send the logs a syslog server
B. Increase the number of logs kept
C. Increase the logging level
D. Increase the size of the partition where log files are stored
Answer: AB
Explanation:
Configure syslog to send logs to syslog server and increase the number of logs kept. This way, the log files are not rotated very quickly.
QUESTION 243
A series of Auto Deploy ESXi 5.x hosts which utilize vSphere Standard Switches are unable to boot. In prior testing, all of the hosts were able to boot successfully.
Which two conditions might cause this issue? (Choose two.)
A. The Hosts are unable to connect to the SAN.
B. The TFTP server is down.
C. The DNS server is down.
D. The DHCP server is down.
Answer: BD
Explanation:
If the TFTP server is down, ESXi will not boot because it needs TFTP to get the information. Similarly, when DHCP is down, it will not assign the IP addresses and ESXi needs IP address to boot properly.
QUESTION 244
An administrator wants to monitor the health status of an ESXi 5.x host. However, when the administrator clicks the Hardware Status tab the following error is displayed.
This program cannot display the webpage
What might cause this problem?
A. The VMware VirtualCenter Management Webservices Service is not started.
B. The required plug-in is not enabled.
C. The VMware ESXi Management Webservices Service is not started
D. The name of the vCenter Server system could not be resolved.
Answer: A
Explanation:
Verify that the VMware VirtualCenter Management Webservices service is running on the vCenter Server system. Navigate to the vCenter Server system in the inventory and select Monitor > Service Health. The page displays the following message if the VMware VirtualCenter Management Webservices service is not started.
Could not get vCenter Health status
If you see this error message, start the VMware VirtualCenter Management Webservices service.
QUESTION 245
An iSCSI array is being added to a vSphere 5.x implementation. An administrator wants to verify that all IP storage VMkernel interfaces are configured for jumbo frames.
What are two methods to verify this configuration? (Choose two.)
A. Run the esxcli network ip interface list command
B. Run the esxcfg-vswif -l command
C. Ensure that the Enable Jumbo Frames box is checked in the VMkernel interface properties in the
vSphere client
D. Ensure that the MTU size is set correctly in the VMkernel interface properties in the vSphere client
Answer: AD
Explanation:
You have to run esxcli network ip interface list command to list all the IPs. Then you need to make sure that MTU size is correctly set in the VMkernel interface properties in the vsphere client.
QUESTION 246
An administrator has configured a vSphere Distributed Switch to send all network traffic to a collector virtual machine for analysis. However, after checking the collector virtual machine several hours later the administrator finds that no data has been collected. vSphere 5.x has been deployed in the datacenter.
Which two items below could be causing this issue? (Choose two.)
A. The source virtual machine does not have Promiscuous Mode enabled.
B. The source and target virtual machines are not both be on the same vSphere Distributed Switch.
C. The port group or distributed does not have Promiscuous Mode enabled.
D. The port group or distributed port does not have NetFlow enabled.
Answer: BD
Explanation:
Requirements for a collector virtual machine to analyze traffic from a vSphere Distributed Switch:
1) The source and target virtual machines must both be on a vNetwork Switch, but can be on any vDS datacenter.
2) The port group on distributed port must have NetFlow enabled. Two methods to migrate a virtual machine from a vSphere Standard Switch (VSS) to a vSphere Distributed Switch (VDS):
1) Migrate the port group containing the virtual machine from a vNetwork Standard Switch using the Migrate Virtual machine networking option.
2) Edit the Network Adapater settings for the virtual machine and select a dvPort group from the list.
QUESTION 247
A vSphere 5 implementation consists of a fully automated DRS cluster with two ESXi 5.x hosts
with the following vSphere Standard Switch configuration.
1. Switch A. three vmnics, one port group named sFTP-PG
2. Switch B. two vmnic, one port group named Web-PG
3. All vmnics are trunked to the same physical switch.
DRS has been configured with an anti-affinity rule for all virtual machines in the Web-PG so that no more than half of the virtual machines run on any given host. The virtual machines on WebPG are experiencing significant network latency. The network team has determined that a performance bottleneck is occurring at the ESXi host level.
Which solution will require the least amount of administrative work and the least amount of service interruption?
A. Migrate Web-PG to Switch A and sFTP-PG to Switch B on each host
B. Move a vmnic from Switch A to Switch B on each host
C. Convert the three Switch Bs to a single vSphere Distributed Switch
D. Use vMotion to redistribute some of the VMs in Web-PG to a different ESXi host
Answer: B
Explanation:
Let us examine this is a problem with resource contention on a NIC on a host. VDS WILL NOT fix the problem because dvuplinks are the same as uplinks on the ESX host experiencing a problem.VMotion should not be a solution, DRS already has VMotion and knows where to place VMs using defined rules.
QUESTION 248
A user attempts a remote SSH connection to a newly-installed ESXi 5.x host to execute some commands. The SSH connection attempt fails, though the user is able to receive a ICMP ping back from the host.
What must the administrator do to enable SSH? (Choose two.)
A. Enable root logon on the ESXi server.
B. Open the SSH port on the ESXi firewall.
C. Start the SSH service on the ESXi server.
D. Create a local user on the ESXi server.

QUESTION 249
An administrator is setting up vMotion in a vSphere environment. A migration is run to test the configuration, but fails.
What could the administrator do to resolve the issue?
A. Ensure the VMkernel port group is configured for Management Traffic.
B. Enable VMkernel port group for the vSphere cluster.
C. Ensure the vMotion enabled adaptors configured for the same subnet.
D. Use a vDS instead of a standard switch.
Answer: C

QUESTION 250
An administrator is unable to connect a vSphere Client to an ESXi 5.x host.
Which option can be selected from the direct console to restore connectivity without disrupting running virtual machines?
A. Restore the Standard Switch from the ESXi host.
B. Restart the Management Agents from the vSphere client.
C. Restart the Management Agent from the ESXi host
D. Disable the Management Network from the vSphere client.
