Pre-Exam test II

What kind of rotation schedule is followed for backups

What time will the backups occur

How long to save backups?

Where is the Media/Documentation stored

Who is responsible for ensuring the backup occured

Who will verify the accuracy of backups

Who will dictate who does the back ups

Who will decide where to buy stuff from

Owned, managed and accessed only by 1 organization

Available for use by general public

Combination of public and private

Shared by 2 or several organizations

Shared by 2 or several organizations

Combination of pubic and private cloud

Private cloud

Allow flexibility in costs (pay on demand)

Scalability and device dependence

Business continuity and Disaster recovery built-in

Highly secure

Customization difficult / expensive

Control / security of data

Moving of application / exporting of data

Eliminate need for on site data center

Scalability and device independence

Takes a toll on IT services

Reduced cost of infrastructure

Less server administration knowledge / costs

Greater system uptime

Scalability

Need QoS agreements to enforce needs

Requires multiple tenants before service is offered

Concern about data security

Challenges with legacy software

Need QoS agreements to enforce needs

Web Hosting

Unable to deploy applications on same day

Eliminate need for own data center (co-locate), leads to reduced cost

Ease of scalability

Strict demand costs

Increase in IT staffing requirements

Ad hoc test environments

Complete systems administration and management

CPU

RAM

Storage (disk space)

Network (capacity and speed)

Printing

The registry hive file format can add and remove keys, subkeys, and values. The registration file format can only add or change keys, subkeys, and values.

The registry hive file format can delete keys and the registration file format can't

Neither can affect the registry.

restores the registry in case of corruption

A major problem was the fact that the operating system had to read both files line by line as it came up, so that the longer the files were, the slower the boot process.

Users were getting themselves into trouble by making changes to the INI files.

It was possible for the user to inadvertently delete an INI file

It was not possible to set security setting on specific file entries.

The files could be renamed

The ussers could delete the INI file while the OS was working
