A.Restore the Standard Switch
B.Restart the Management Agents
C.Restart the Management Network
D.Disable the Management Network
Answer: B
Explanation:
When you are not able to connect ESX server to vCenter, or when you cannot connect to ESX server from VI client it may be necessary to restart the management agents on your ESX Server.

QUESTION 41
Traffic Shaping can be configured on the following vSphere elements (Choose Two)?
A.On a vNetwork Distributed Switch dvPort or the entire dvPort Group for outbound traffic only
B.On a vNetwork Standard Switch port group or the entire vSwitch for outbound traffic only
C.On a vNetwork Standard Switch port group or the entire vSwitch for inbound traffic only
D.On a vNetwork Distributed Switch dvPort or the entire dvPort Group for inbound and outbound traffic
Answer: BD
Explanation:
Bi-directional traffic shaping – vDS expands upon the egress only traffic shaping feature of Standard Switches with bi-directional traffic shaping capabilities. Egress (from VM to network) and now ingress (from network into VM) traffic shaping policies can now be applied on DV Port Group Definitions.

QUESTION 42
When creating a Service Console port, what is the purpose of the gateway device (Choose Two)?
A.The gateway device is the network adapter used for the default route.
B.A gateway device is always required.
C.The gateway device is the Service Console port used for VMkernel networking.
D.A gateway device is required when 2 or more uplinks are using the same subnet.
Answer: AD
Explanation:
ESX Configuration Guide ESX 4.0 vCenter Server 4.0, page 25.
For the service console, the gateway device is needed only when two or more network adapters are using the same subnet. [D above]
The gateway device determines which network adapter is used for the default route. [A above]

QUESTION 43

A.A Service Console port can be cloned from an existing vNetwork Standard Switch
B.A Service Console Network Adapter can be associated with an existing port group on a Network Distributed Switch
C.A Service Console Network Adapter can be created along with a Service Console port group on the selected vNetwork Distributed Switch
D.A Service Console Network Adapter can be created and added to a Standalone Port
E.A Service Console port can be migrated from an existing vNetwork Standard Switch
Answer: BDE

QUESTION 44
Networking policies, such as traffic shaping and security, can be configured on the following vSphere elements?
A.On the port group and the physical network interface
B.On the port group and the vSwitch
C.On the vSwitch and the attached virtual machine
D.On the physical network interface and the vSwitch
Answer: B
Explanation:
Networking policies, such as traffic shaping and security, can be configured on the port group

Networking policies, such as traffic shaping and security, can be configured on the vSwitch

QUESTION 45
When configuring multiple service console connections, which of the following is true?
A.The service console connections must be attached to different vmnics
B.The service console connections must be configured on different virtual switches
C.The service console connection must be configured on different networks
D.The service console connections must be configured on the same virtual switch
Answer: C

QUESTION 46
In which format does an iSCSI target ID appear?
A.iqn.<year-mo>.<reversed_domain_name>:<unique_name>
B.iscsi.<year-mo>.<forward_domain_name>:<unique_name>
C.iqn.<ip_address>.<reversed_domain_name>
D.iscsi.<organizational_unit>.<forward_domain_name>:<unique_name>
Answer: A
Explanation:
Wikipedia – iSCSI
Addressing
Special names refer to both iSCSI initiators and targets. iSCSI provides three name-formats:
1. iSCSI Qualified Name (IQN) – Format: iqn.yyyy-mm.{reversed domain name} (e.g. iqn.2001-04.com.acme:storage.tape.sys1.xyz) (Note: there is an optional colon with arbitrary text afterwards. This text is there to help better organize or label resources.) [A above]
2. Extended Unique Identifier (EUI) – Format: eui.{EUI-64 bit address} (e.g. eui.02004567A425678D)
3. T11 Network Address Authority (NAA) – Format: naa.{NAA 64 or 128 bit identifier} (e.g. naa.52004567BA64678D)

QUESTION 47
Which security technology does VMware iSCSI use?
A.IPSec
B.PAP
C.CHAP
D.MSCHAPv2
E.AES
Answer: C
Explanation:
iSCSI SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 37.
Because the IP networks that the iSCSI technology uses to connect to remote targets do not protect the data they transport, you must ensure security of the connection. iSCSI requires that all devices on the network implement Challenge Handshake Authentication Protocol (CHAP), which verifies the legitimacy of initiators that access targets on the network.
B. reboot a virtual machine
C. run a script
D. reboot an ESX Server
E. send an e-mail
Answer: B, C, E
Basic System Administration ESX Server 3.5, ESX Server 3i version 3.5 VirtualCenter 2.5, page 314, 315.
There are several types of alarm notification methods:
Send a notification email message [E above]
Send a notification trap
Run a script [C above]
Suspend the virtual machine
Power off the virtual machine
Reset the virtual machine [B above]
