Virtualization, Storage, and Cloud Technologies Chapter 7 Study Guide

What are the two major console interfaces used to work with an ESXi host

Direct Console User Interface (DCUI) and vCLI

You are attempting to utilize a packet capturing software in your studies of a

network's traffic, however, your virtual machine running on vSphere is unable to put

the network adapter in promiscuous mode. What is the most likely reason for the

failure?

A network security policy is preventing the use of a promiscuous mode interface.

What virtual machine configuration file holds the virtual machine's snapshot state

information?

VM_name.vmss

What command can you use to add a comma separated list of users to an ESXi server

using VCLI?

vicfg-user -u

A virtual machine providing services for your network was recently hacked and used

to spoof MAC addresses on your network to target other systems. What policies

could you set to prevent this from reoccurring?

The MAC address changes and forged transmits policies should be set to "Reject".

You are trying to support a VOIP application on a virtual machine, and need to

prioritize VOIP traffic. What kind of virtual switch policy should you use?

traffic shaping policy

What traffic shaping policy option determines the max number of kilobits per second

to allow across a port when it is sending a burst of traffic?

peak bandwidth

What traffic shaping policy option determines the number of kilobits per second to

allow across a port, averaged over time?

average bandwidth

When a virtual machine is converted to a template on vSphere, what happens to the

.vmx configuration file?

It is replaced by a .vmtx template configuration file.

What is NOT one of the valid choices available for ESXi's virtual SCSI adapter?

BusLogic SAS

What are the two GUI clients provided by VMware for use with vSphere?

vSphere Web client and vSphere Client

When running the vmkfstools command with the --server option pointing to a

vCenter Server system, what option should be used to select the proper ESXi host to

run the command against?

--vihost

You are using a gigabit Ethernet adapter (vmnic1) on an ESXi host, and you have

found that the status screen displays the adapter as being connected at 100 Mb, full

duplex. You have verified that the switch your server connects to has 1 Gbps capable

ports. What is most likely the problem?

The adapter has been manually configured to a speed of 100 Mb, duplex operation.

What sort of application might require the promiscuous mode security policy to be

configured to "accept" in order to support?

A network monitoring application such as an intrusion detection system (IDS)

You are configuring a Linux based 64-bit virtual machine for use on a vSphere host.

Based on this information, what will be the default network adapter type and why?

The e1000 adapter type will be used, because it is the default for 64-bit guest

operating systems.

While using vSphere for free, you are limited to how many virtual CPUs?

8

What virtual disk file type takes the longest to create?

thick provision eager zeroed

What type of virtual switch exists only within a single vSphere hypervisor?

standard

What statement regarding the use of distributed switches is accurate?

A distributed switch can be shared among multiple associated vSphere hosts, providing consistent

network configuration.

A security policy has been applied to an individual port on a virtual switch. The switch

itself has a conflicting policy configured. What setting has priority?

The settings on the port will have priority, because the policy is overridden at the port level

What virtual network adapter type should you use if you need to support fault

tolerance as well as record/replay for network traffic?

vmxnet3

Under what conditions might a virtual machine have a lock file?

A lock file can exist when a virtual machine is stored on an NFS based data store.

What configuration file name would be assigned to the Raw Device Map (RDM)

pointer file for a VM named Srv1?

Srv1.rdm.vmdk

How many archive logs are maintained for a virtual machine at any one time?

six

What is the maximum number of vCPUs supported by the fully licensed version of the

vSphere hypervisor?

128 vCPUs
