QUESTION: 85

A snapshot is a feature that can be used in hypervisors to:

roll back firmware updates.
restore to a previous version.
roll back application drivers.
perform a backup restore.

Answer(s): B

Explanation:

A snapshot is a feature that can be used in hypervisors to restore to a previous version. A snapshot is a point-in-time copy of a virtual machine (VM) that captures the state and data of the VM at a specific moment. A snapshot can be created instantly and with minimal overhead, as it only stores the changes made to the VM after the snapshot was taken. A snapshot can be used to restore the VM to its previous state in case of data loss or corruption.

A server administrator needs to deploy five VMs, all of which must have the same type of configuration.
Which of the following would be the MOST efficient way to perform this task?

Snapshot a VM.
Use a physical host.
Perform a P2V conversion.
Use a VM template.

Answer(s): D

Explanation:

Deploying a virtual machine from a template creates a virtual machine that is a copy of the template. The new virtual machine has the virtual hardware, installed software, and other properties that are configured for the template.

The most efficient way to perform the task of deploying five VMs with the same type of configuration is to use a VM template. A template is a preconfigured virtual machine image that contains an operating system, applications, settings, and other components. A template can be used to create multiple identical or customized VMs quickly and easily, without having to install and configure each VM from scratch. A template can save time and ensure consistency across VMs.

QUESTION: 88

The Chief Information Officer (CIO) of a datacenter is concerned that transmissions from the building can be detected from the outside.
Which of the following would resolve this concern? (Choose two.)

RFID
Proximity readers
Signal blocking
Camouflage
Reflective glass
Bollards

Answer(s): C,E

Explanation:

The best solutions to resolve the concern of transmissions from the building being detected from outside are signal blocking and reflective glass. Signal blocking is a method of preventing or interfering with electromagnetic signals from escaping or entering a certain area. Signal blocking can be achieved by using various materials or devices that create physical barriers or generate noise or jamming signals. Signal blocking can protect data transmissions from being intercepted or eavesdropped by unauthorized parties. Reflective glass is a type of glass that has a coating or film that reflects light and heat. Reflective glass can reduce glare and solar radiation, as well as prevent visual observation from outside. Reflective glass can enhance privacy and security for datacenter operations.
