Your client has been experiencing problems with his aging in-house infrastructure, and is extremely concerned about managing the cost of maintaining his online presence. After deciding that the cost of developing a sound DR plan more than makes up for the negative impact of being off-line, the board has directed you to prepare a proposal that achieves an RTO of 20 hours, an RPO of 1 hour, and keeps the costs of meeting those target time-windows to a minimum. They have also mandated the use of the AWS Storage Gateway to mitigate the risk associated with a catastrophic NAS failure. Which of the following solutions best meet the requirements?

Answers

Answer 1

Explanation:

Working with my customer's engineers to help identify the key servers and the data. And help them to setup an AWS account with the IAM users, groups and the roles. Next build the templates of a critical web or app servers and then save them as AMIs. Agreeing upon the RDS specifications which meet a stated requirements and set up a Storage Gateway as well as a Snapshot schedule in order to meet the RPO. Document  or automate the steps to help initiate the EC2 instances, the RDS instance and the steps to replace the latest data from  Storage Gateway snapshots into the RDS, also if any DNS changes. Now test the process with each of my Operations team shifts.

Answer 2

Utilizing AWS Storage Gateway, EC2 for Disaster Recovery, and S3 replication addresses the client's RTO and RPO requirements while maintaining cost-effectiveness. This approach involves automated backups, low-latency storage, and ensuring data redundancy. Regular testing and validation of the DR plan ensure its reliability.

To address your client's requirements of achieving an RTO of 20 hours, an RPO of 1 hour, and ensuring cost-effectiveness while using AWS Storage Gateway, the following solution is recommended:

Utilize AWS Storage Gateway - File Gateway for seamless integration with S3, enabling a low-latency and cost-effective storage solution.Implement AWS Backup to automate backup processes, ensuring that data can be quickly restored, meeting the RPO and RTO targets.Use AWS EC2 for Disaster Recovery: Spin up EC2 instances using AMIs of your current setup in case of a disaster, which can be pre-configured to minimize downtime and restore operations within the 20-hour RTO window.Leverage S3 Versioning and Cross-Region Replication to ensure data redundancy and availability, protecting against catastrophic NAS failures.Implement Regular Testing and Validation of your DR plan to ensure it works efficiently when needed, thus minimizing the risks associated with outages.

This solution achieves the desired RTO and RPO by leveraging Amazon's comprehensive cloud infrastructure, ensuring fault tolerance, and keeping costs manageable through scalable pay-as-you-go services.

In which tragic form are the central figures of the play caught in a series of tragic circumstances?

Answers

Answer:

Both traditional and modern tragedy

Explanation:

Traditional tragedy or classical tragedy is the tragedy that consists of a single time span, setting, and one main protagonist.

Whereas, Modern Tragedies consists of more than one protagonist, realistic time, and more than one plot.

The similarities between both types of tragedy are that they both have catharsis, which means that they both have there main characters caught in tragic circumstances.

Final answer:

In tragedy, the central figures face tragic circumstances that emerge from their personal failings and external factors, culminating in a Scene of Suffering. This structure and the use of hamartia are designed to evoke pity and fear in the audience, leading to catharsis.

Explanation:

In a tragedy, the central figures, or protagonists, are typically caught in a series of tragic circumstances arising from a combination of personal failings (known as hamartia) and factors beyond their control. The plot usually follows a structure that begins with a Complication, leading to a climax, and concludes with an Unraveling or Denouement. The protagonist's hamartia (a great error or frailty) results in unforeseeable and unintended consequences that culminate in a Scene of Suffering, eliciting pity and fear from the audience.

For example, in William Shakespeare's Romeo and Juliet, the protagonists' own impulsive decisions and cruel twists of fate lead to their untimely deaths. The audience witnesses the height of their suffering in the tragic final scene where timing and misunderstandings result in both characters' self-inflicted deaths.

This sense of catharsis is central to the genre, where the story of the character elicits a cleansing of emotions. The most powerful elements of emotional interest in tragedy include Peripeteia (Reversal of the Situation) and Recognition scenes, which are all part of the carefully constructed plot designed to evoke a profound response from the audience.

Answer: 50 percent

Explanation: Learning is about repeating a process and connecting novel information to knowledge you already have. Accessing information becomes easy when multiple pathways exist to that information. What this implies is that thinking about a particular thing more often builds a strong connection of that particular thing in your brain.

It is said that human beings retain 10 percent of information they read, 20 percent of the information they hear, 30 percent of information they see with their eyes, 50 percent of information they read/see and hear, 70 percent of what they say and write, and 90 percent of what they do. Hence the percentage of information retained when a person reads and listens to food safety information is 50%.

Jean's and Carol's different reactions to divorce show individual differences in coping and resilience, with Jean struggling and Carol seeing it as a chance to pursue personal dreams.

Explanation:

The differing reactions of Jean and Carol to their divorces illustrate individual differences in coping mechanisms and resilience after significant life changes. Jean's reaction of becoming depressed and isolating herself may suggest that she perceives the divorce as a threat, possibly fearing loneliness or a change in lifestyle. In contrast, Carol sees the divorce as a challenge, using it as an opportunity to pursue her dream career. This proactive approach may involve a sense of optimism and self-improvement.

One key aspect of social psychology is understanding how people react and adapt to life-altering events such as divorce. Factors contributing to these reactions can include personal beliefs, past experiences, support systems, and perception of the event as either a threat or a challenge. While Jean's response indicates a struggle with the situation, Carol's reaction shows a positive use of the event to make significant life changes and pursue personal growth.

Why doesn’t Victor protect his wife, Elizabeth, from the monster’s attack on the night of their wedding?

Answers

Answer:

Because he misunderstands the monster's warning and he thinks that Elizabeth could protect herself.

Explanation:

During the course of the novel Victor and the monster have become irreconcilable enemies, leaving no truce in the intention of destroying each other.

The monster has committed several criminal acts in pursuit of his revenge on his creator but Victor has stopped acting rationally by letting himself be carried away by a strong mental instability, disregarding the monster's ability to find and punish him.

Elizabeth represents the peace of mind that Victor needs, the selfless altruism of unconditional love but also the rational strength that the creator does not have.

Actually, Victor is desperate in the village of Como where they had retired to celebrate their wedding night despite the gloomy atmosphere and the bad omens.

Victor Frankenstein becomes more and more anxious because he is certain that on that very night, he or his creature will die tonight.

Elizabeth, seeing him so agitated and indisposed, begs him to tell her what he is so afraid of. Victor tries to comfort her, but cannot answer her question, and only asks that, in order to prevent his beloved from seeing the monster, she should retire to her room while he watches the residence and the surroundings for any trace of the monster.

Finally, Victor hears a horrible scream coming from the bedroom where Elizabeth is resting, but it is already too late: Elizabeth is lying strangled and Victor is aware of the great mistake he has made.

In Mary Shelley's 'Frankenstein', Victor misinterprets the monster's threat and focuses on protecting himself, failing to ensure Elizabeth's safety on their wedding night, which results in her death.

The question pertains to Mary Shelley's novel Frankenstein, in which Victor Frankenstein does not protect his wife, Elizabeth, from the monster's attack on their wedding night. Victor is misled by the monster's previous threat that he will be with Victor on his wedding night. Victor interprets this to mean that the monster intends to kill him, not Elizabeth, so he prepares to confront the monster himself. In his focus on protecting himself, he tragically neglects to safeguard Elizabeth, leading to her death at the hands of the monster, which could be considered a manifestation of Victor's hubris and his failure to grasp the full consequences of his actions.
