An organization is building a single virtual environment that will host customer applications and data that require availability at all times. The data center that is hosting the environment will provide generator power and ISP services. Which of the following is the best solution to support the organization's requirement?
To ensure continuous availability of customer applications and data, a UPS (Uninterruptible Power Supply) is essential. Although the data center provides generator power, generators typically take a few minutes to start up after a power outage. During this window, a UPS provides immediate power to keep systems running, ensuring there is no interruption in service. This is critical for meeting the requirement of maintaining availability at all times.
This is the only solution that make sense and address the issue! I have no idea why there is a confusion ? It’s electricity issue, no NIC nor Load Balancing have anything to with it! Please do not confuse others who come after you and get it wrong because of your inputs!
NIC teaming makes the most sense here. NIC teaming provides performance, load balancing and redundancy benefits. B. Cloud backups - though critical, this does not ensure availability of customer applications and data C. A load balancer appliance - the company is building virtual infrastructure, an appliance is hardware, therefore is not a fit for the planned virtual solution. D. UPS - the data centre is already providing a generator, the redundant power requirements have been addressed.
NIC teaming will be useless if the power goes out and you have to wait a few minutes for the generator to come on. So having UPS will ensure constant availability of power.
Generators can take minutes to power up the building during a power outage, losing data. A UPS will be useful in the time between power failure and the generator powering up. Think of a UPS as a bridge in between the two.
You need UPS before a generator kick on
Have to go with C, because, they are building a single virtual environment, meaning the ISP is providing all the hardware (so you can't change or buy any hardware, like NICs and UPSs) as it's a cloud provider. A load balancer appliance can be a virtual appliance. (don't get confused with the term appliance - it can be software OR hardware). Cloud backups are "redundancy" NOT "availability"
The requirement is availability of customer applications and data at all times. The information about the data centre seems out of place, considering the requirement and the question. Also, you cannot setup your own UPS in the data centre. A load balancing appliance can detect server failures or network issues and automatically redirect traffic to healthy servers. This ensures uninterrupted service, even if some servers or resources fail. This is addresses the organizations requirement.
I change my mind, NIC teaming makes the most sense here. NIC teaming provides performance, load balancing and redundancy benefits. B. Cloud backups - though critical, this does not ensure availability of customer applications and data C. A load balancer appliance - the company is building virtual infrastructure, an appliance is hardware, therefore is not a fit for the planned virtual solution. D. UPS - the data centre is already providing a generator, the redundant power requirements have been addressed by the service provider.
Read carefully: The organization is the one that is building the virtual environment. The data center is the one that is providing the power generator and the ISP The question is asking which option is going to help the organization, not the data center.
then according to you what is the best fit?
C. A load balancer appliance. A load balancer appliance is a device or service that distributes network or application traffic across multiple servers, increasing the capacity and relaibility of application. A load balancer appliance can handle peak traffic peak traffice times, improve performance, and provide security feattures. NIC teaming, Cloud backups, and UPS are not sufficient to ensure availability at all times, as they do not address the scalability and performance issues that may arise from high demand and usage.
i was also confused what the question was asking but i reread it and for everyone that is confused the question said " availability at all times" a generator would give power, but it takes time to kick in. now UPS would be used within a second of power going out to act as the generator until the generator powers, and this provides the availability.
most of that question was useless information to trick you into picking a wrong answer so just read and pay attention to what the question is asking.
I have to go with C: Load Balancer Appliance. The reasoning is companies do not have access to the cloud hardware so they can't implement anything. They can request additional hardware, however. This is another one of Comptia's trick questions.
This is wrong. The question doesn't mention Cloud Service Providers. The question states the company is "building" a virtual infrastructure in a datacenter. Physical datacenters that you can touch and feel still exist. You are the trick answer.
no brainer
As others have noted, the question states "...apps and data require availability AT ALL TIMES..." To me, that makes D the most logical choice.
D. UPS (Uninterruptible Power Supply). A UPS system provides battery backup power in the event of a power outage, allowing critical systems to remain operational until generator power can be restored. This ensures that the virtual environment remains online and accessible to customers even during power disruptions, thus meeting the requirement for continuous availability.
D: UPS because of the startup delay of the generator kicking in. Choice C would be good once all power is operational.
Professor Messor "During that 10 or 15 seconds, though, you will need some type of internal power in the building to make sure that all of your systems remain up and running, which is why you might combine both the UPS and the generator power to make sure that all of your computing systems stay active and available."
I think the important information here is the "all the time" requirement. Even though the generator provides a long term solution until the electricity is back, it won't kick in immediately after the outage. So, the answer is UPS I think. It will take over right after the outage until the generator is up and ready to go and so the costumers won't experience any downtime.
The question states (apps and data require availability at all times) Given the choices UPS best answer - because any interruptions of power would disrupt NIC, LB and any backups. (Poorly worded question) maybe they should of added high availability in the question.
A UPS provides temporary power during electrical outages, ensuring that the servers and other critical infrastructure remain operational until the generator can take over
