A company recently launched a variety of new workloads on Amazon EC2 instances in its AWS account. The company needs to create a strategy to access and administer the instances remotely and securely. The company needs to implement a repeatable process that works with native AWS services and follows the AWS Well-Architected Framework. Which solution will meet these requirements with the LEAST operational overhead? A. Use the EC2 serial console to directly access the terminal interface of each instance for administration. B. Attach the appropriate IAM role to each existing instance and new instance. Use AWS Systems Manager Session Manager to establish a remote SSH session. C. Create an administrative SSH key pair. Load the public key into each EC2 instance. Deploy a bastion host in a public subnet to provide a tunnel for administration of each instance. D. Establish an AWS Site-to-Site VPN connection. Instruct administrators to use their local on-premises machines to connect directly to the instances by using SSH keys across the VPN tunnel.

Q9B- Context- Alice and Bob are members of the same Kerberos realm. They are both currently logged in with active session keys from the Kerberos KDC (key distribution centre). As per the Kerberos standard, the KDC has created unique session keys for both Alice and Bob, and then discarded them once received by the respective users. Alice wants to access a resource owned by Bob and contacts the KDC to request the necessary material. Answer the following questions about this scenario: Q- How can the KDC verify Alice’s identity after discarding her session key?

Please build a web server on your Raspbery Pi virtual host and publish a dynamic website that shows the characteristics of your virtual system and data about you as a current user i.e. Web page with information about the version of the operating system, what modules are configured and working, which interfaces are included (HDMI, USB, etc.), user name, time login etc. (at least 6 parameters). Complete the web page with a survey for the loT class! You have complete freedom for a design of the web page!
You’re the database administrator for a large grocery store chain. When you leave on Wednesday, there are no problems. When you arrive on Thursday (the day a new sale starts), you learn that the network is down. It went down before the local stores could download the new sales prices. All scanned goods will ring up at the price they were last week (either sale or regular) and not at current prices. The provider says he is working on the network problem but can’t estimate how long the repairs will take. How do you approach the problem?

Computer Science Draw the sequence diagram for a typical, older, "classic", single-window-drive-through fast-food restaurant protocol. For this use case, assume no online pre-ordering; assume a single pay and get your food window. Use 3 roles (human actors) -- imagine who would be most important in this process -- and 3 system objects (the microphone/speaker "board"; the window attendantʻs console (display/keypad); the cookʻs console) to describe the system for ordering. Include some typical messages
We limit ourselves to the hour by querying the interfaces consecutively, one by one. There is nothing to stop us from querying both interfaces at the same time, which will reduce their response time.We take advantage of Go's simultaneous playback capabilities across Go sub-units, goroutines and Channels. We will place each query in its own subunit and run it in parallel. We then combine the answers into one channel and then calculate averages when all queries are complete.

I am using SwaggerHub to document the API endpoints for my web application, but my app uses firebase authentication for login/register which is needed to receive a bearer token in order to perform the basic CRUD operations for the other endpoints. I am trying to figure out how to obtain the bearer token by logging in through SwaggerHub login api, but firebase authentication handles the login and register component, therefore I cannot include the endpoints that will generate the bearer token for me to test the other endpoints.

To reduce the communication cost of remote applications with high access frequency, it is required to perform a horizontal fragmentation given the following application information: App1 : Compute payment = HOURS * PAY_RATE for every employee working in a “NEW YORK” project.App2 : Compute payment for every employee working in a “PARIS” project. App3 : Find the basic salaries of mangers of departments that have projects in “NEW YORK” or “TOKYO”. App4 : Find the salaries of mangers of departments that have projects in “PARIS” and “TOKYO”.App5 : Find the salaries of employees working in departments in “PARIS” with monthly basic salary < 100000”. App6 : Find the names of employees in “HEAD_OFFICE” department. Define fragments using SQL and relational algebra AS YOU CAN Answer in details
