Exam SY0-601 topic 1 question 478 discussion

The most cost-effective disaster recovery site is a cold site. A cold site is a disaster recovery site that provides only the basic facilities, such as power, cooling, and physical space, but does not have any of the hardware or software needed to run the organization's systems. This means that the organization would need to purchase and install the necessary equipment in the event of a disaster, but the cost of maintaining the cold site is significantly lower than that of a warm or hot site, which are pre-configured with the necessary hardware and software. A hot site is the most expensive to operate, as it is a fully functional and redundant facility with all the necessary hardware and software to run the organization's systems. A warm site is a compromise between a hot and cold site and provides some pre-configured hardware and software, but not to the same extent as a hot site. A hybrid site is a combination of different disaster recovery site types and is typically used when an organization has different tiers of systems with different recovery time objectives.

Cold water is the cheapest, warm and hot takes more money to heat it up.

what is ng, its not in acronym list, cant make sense of it from online, ai search

Cold sites are less expensive to operate compared to warm and hot sites because they provide only the basic infrastructure without active equipment or data replication. They require setup and configuration when activated during a disaster, which may take longer compared to warm and hot sites, but they offer significant cost savings in terms of maintenance and operational expenses.

The same security procedures must apply to redundant sites, spare systems, and backup data as apply to the main copy. For many companies, the most cost-effective solution is to move processing and data storage to the cloud.

Least expensive and most cost-effective DO NOT mean the same thing. A cold site is the least expensive option to implement but not necessarily the most cost-effective site to operate.

C. Hot site

B. Cold site

>>>>>B<<<<<<<<<<< The most cost-effective disaster recovery site to operate is a "Cold site". A cold site is a disaster recovery site that provides only the basic infrastructure, such as power and cooling, but does not have any hardware or software installed. This means that the organization will need to provide and install their own equipment and software in the event of a disaster. While this may take longer to recover from a disaster, it is the most cost-effective option as the organization does not need to pay for ongoing maintenance and operational costs of the site.

-B is correct A cold site is the most cost-effective disaster recovery site to operate. A cold site is an off-site location that is not set up for immediate use but has the necessary infrastructure to support IT operations. Typically, a cold site only has the physical infrastructure, such as power and cooling, and lacks IT equipment. In the event of a disaster, IT equipment would need to be installed, configured, and restored from backups before the site could be used. While a cold site requires more lead time to restore IT operations compared to other disaster recovery site options, it is significantly less expensive to operate. This is because the organization only pays for the physical infrastructure and does not have the ongoing costs of running and maintaining IT equipment.
