3. Commonly Asked Amazon Web Service Interview Questions
Following are some commonly asked Amazon Web Service Interview Questions –
Q.9 Explain the difference between instance store and EBS?
Answer- Few of the Amazon EC2 instance types are in a form of directly attached, block-device storage call as the instance store. The data stored in instance store volumes is not persistent through instance stops terminations as the instance store is ideal for temporary storage. More detailed information about the instance store can found at Amazon EC2 Instance Store.
If a user wants to retain longer-term, or if they need to encrypt the data. It is recommended using EBS volumes instead. EBS volume secures the data through instance stops and terminations. There is a feature such that it can easily back up with EBS snapshots. It can remove from instances and reattached to another, and support full-volume encryption.
Q.10 Explain Amazon LightSail.
Answer- Amazon LightSail helps for developers, the users who are in need of Simple Virtual Private Servers. LightSail provides several capacities and capabilities such as compute, storage, and networking. Which helps to deploy and manage websites and web applications in the cloud. LightSail helps the user to launch the project quickly by providing the facilities such as a virtual machine, SSD-based storage, data transfer, DNS management, and a static IP.
Q.11 How can a user create a LightSail instance?
Answer- After logging in to Lightsail, the user can use the Lightsail console, command line interface (CLI), or API to create and manage instances.
The first time the user logs in to the console, choose to create Instance. The create instance page is where the user can choose the software, location, and name for the user instance. Once the user chooses to create, the user new instance will spin up automatically within minutes.
Q.12 How will a user connect with a Lightsail instance?
Answer- Lightsail offers a 1-click secure connection to the user instance’s terminal right from the user browser, supporting SSH access for Linux/Unix-based instances and RDP access for Windows-based instances. To use 1-click connections, launch the user instance management screens, click Connect using SSH or Connect using RDP, and a brand new browser window opens and automatically connects to the user instance.
If the user likes to attach to the user Linux/Unix-based instance using the user own consumer, Lightsail can do the SSH key storing and management work for the user, and supply the user with a secure key to use in the user SSH consumer.
Q.13 How will a user use IPs in Lightsail?
Answer- Each Lightsail instance automatically gets a personal IP address and a public IP address, that are accessible from the web. The user will use the non-public IP to send data to different Lightsail instances and AWS resources privately, for free. The user will additionally substitute as static IP for the general public IP of a Lightsail instance.
Q.14 What are DNS records?
Answer- DNS could globally distribute service that interprets human decipherable names like computer network.example.com into numeric IP addresses, like 192.0.2.1 that computers use to attach to every different. With Lightsail, the user will simply map the user registered domain names like photos.example.com to the general public IPs of the user Lightsail instances. During this method, once users sort human decipherable names like example.com into their browsers, Lightsail automatically interprets the address into the IP of the instance the user would like to direct the user users to. Each of those translations is said as a DNS question.
It’s important to understand that so as to use a site in Lightsail, the user want to initial register it. The user will register new domains using Amazon Route fifty-three, or the user most popular DNS registrar.
Q.15 How will a user manage firewall settings for the instance?
Answer- Yes. The user will manage the data traffic for the instances by using the Lightsail firewall. From the Lightsail console, the user will set rules regarding that ports of the user instance are publically accessible for various kinds of traffic.
Q.16 How will a user make a copy the instances?
Answer- If the user would like to make a copy the user data, the user will use the Lightsail console or API to require a photograph of the user instance. If there’s a failure or dangerous code reading, the user will later use the user instance photograph to form a current instance. We have a tendency to suggest stopping the user instance quickly once taking a photograph, to make sure the user knowledge is complete and not corrupted in any method.
