What Is Cloudtrail And How Do Cloudtrail And Route 53 Work Together
CloudTrail is a service that captures information about every request sent to the Amazon Route 53 API by an AWS account, including requests that are sent by IAM users. CloudTrail saves log files of these requests to an Amazon S3 bucket. CloudTrail captures information about all requests. You can use information in the CloudTrail log files to determine which requests were sent to Amazon Route 53, the IP address that the request was sent from, who sent the request, when it was sent, and more.

How Do You Differentiate Between Symmetric And Asymmetric Encryption
While symmetric encryption uses a single key for encryption and decryption, asymmetric encryption uses a public key for encryption and a private key for decryption. The success of symmetric encryption necessitates a secure exchange of the key, and the technique is typically used to transfer large volumes of data. Asymmetric encryption is a slower but more secure technique that is generally deployed to transfer small amounts of data. While symmetric encryption offers confidentiality, asymmetric encryption guarantees confidentiality as well as authenticity and non-repudiation.

Question 1 What Is The Difference Between Iops And Throughput
This question is related to storage. If youre going to build storage architectures, you must know, because different applications require different levels of latency versus differentlevels of throughput.
IOPS, or Input and Output Operations Per Second determines how frequently you canread and write to the disc.
Thats the speed of disk access.
IOPS is related to latency, and is the amount of latency.
We can compare IOPS to the speed of a car that could drive at 200 miles an hour. The higher the IOPS: the more read/write operations per second, thus lower latency. NVME drives and SSD drives tend to have relatively low latency because the read/write operations are very fast.
Magnetic drives by comparison typically have much higher latency and much lower IOPS.
As mentioned, latency is measured in IOPS, and theres an inverse relationship between the amount of IOPS and the actual latency on the network.
Throughput is related to the amount of data and is the amount of data that can be moved at any one period of time.
We can compare throughput to whatever the cars trunk can carry. A car, a tractor-trailer, or a freight train would differ you could carry a lot more stuff in the latter.
Video editors need drives that have very high throughput because theyre working with large file sizes. They can tolerate a little bit of latency.
A database needs extreme speed in terms of read and write operations per second, a higherIOPS but is not moving large amounts of data.
Explain The Difference Between Cloud And Traditional Data Centers
- The traditional data center is expensive due to heating and hardware/software issues. Mostly, the expenditure is on the maintenance of the data centers.
- Cloud is scaled up when there is an increase in demand, hence such expenditure issues are not faced in Cloud Computing.

What Is The Difference Between Scalability And Elasticity
Scalability is the ability of a system to increase its hardware resources to handle the increase in demand. It can be done by increasing the hardware specifications or increasing the processing nodes.
Elasticity is the ability of a system to handle increase in the workload by adding additional hardware resources when the demand increases but also rolling back the scaled resources, when the resources are no longer needed. This is particularly helpful in Cloud environments, where a pay per use model is followed.

What Is The Etl Procedure
In data warehousing, data pipelines are frequently used to perform an extract, transform, and load method. ETL solutions run outside of the data warehouse, allowing the data warehouses resources to be focused on concurrent querying rather than data preparation and transformation. One disadvantage of performing the transformation outside of the data warehouse is that it necessitates learning new tooling and languages to represent the transforms.

Where Do You Think An Ami Fits When You Are Designing An Architecture For A Solution
AMIs are like templates of virtual machines and an instance is derived from an AMI. AWS offers pre-baked AMIs which you can choose while you are launching an instance, some AMIs are not free, therefore can be bought from the AWS Marketplace. You can also choose to create your own custom AMI which would help you save space on AWS. For example if you dont need a set of software on your installation, you can customize your AMI to do that. This makes it cost efficient, since you are removing the unwanted things.

Can You Reset A Password
BIOS is a firmware located on a memory chip, often in a computers motherboard or system board. A typical BIOS security feature is a user password that must be entered to boot up a device. If you wish to reset a password-protected BIOS configuration, youll need to turn off your device, locate a password reset jumper on the system board, remove the jumper plug from the password jumper-pins, and turn on the device without the jumper plug to clear the password. This will reset the BIOS to default factory settings.
