ACA Cloud Security Interview Questions
While some interviewers have their own method of questioning, the majority of job interviews follow a set of questions and responses (including some of the most often-asked behavioural interview questions). Here are some of the most common interview questions, as well as some of the best answers. To begin, consider the following professional advice for preparing for your ACA Cloud Security interview:
1. What is a Systems Integrator, exactly in ACA Cloud Security?
A systems integrator in Cloud Computing is either a person or an organisation with experience compacting component subsystems and ensuring that they work together.
2. What are some of the databases available on open-source cloud computing platforms in ACA Cloud Security?
You may mention some of the databases on which you have worked. Google BigTable, Couch DB, Amazon SimpleDB, Lucid DB, Cloud-based SQL, and Mongo DB are several open-source cloud computing platform databases.
3. How does cloud computing deliver on-demand functionality in ACA Cloud Security?
Cloud computing has a feature for subscribers that gives them on-demand access to virtualised IT resources. To provide flexible resources, cloud computing uses a common pool that includes networks, servers, applications, services, and storage.
4. Can you explain the distinction between cloud computing and mobile computing in ACA Cloud Security?
The concepts of cloud computing and mobile computing are quite similar. Cloud computing gives consumers access to data based on their needs, whereas mobile computing gives users access to data for storing and managing with a user-friendly interface.
5. Can you explain the distinction between cloud computing and mobile computing?
The concepts of mobile computing and cloud computing are similar. The concept of cloud computing is used in mobile computing. In mobile computing, programmes run on a remote server and provide the user access to storage and management, while cloud computing provides users with the data they demand.
6. Explain the distinctions between elasticity and scalability.
In cloud computing, elasticity ensures that the resources assigned match the actual amount of resources required at any given time. Scalability in cloud computing, on the other hand, deals with an application’s changing needs within the infrastructure’s limitations. It achieves it by adding or removing resources to suit the application’s needs.
7. What is the term “EUCALYPTUS”, and how does it apply to cloud computing?
The abbreviation for Elastic Utility Computing Architecture for Linking Your Programs is ‘EUCALYPTUS.’ It’s an open-source cloud computing software platform that can create its own data centre in a private cloud. EUCALYPTUS is a cloud computing platform that uses clusters to build public, private, and hybrid clouds.
8. What is a public cloud, and how does it work?
Third-party suppliers provide public clouds and computing services delivered through the public internet. This means that anyone interested in using or purchasing these services can do so. Microsoft Azure, for example, is a public cloud.
9. What are the advantages of cloud computing in terms of security?
One of the most advantageous features of cloud computing is that it protects against distributed denial of service attacks. It allows the user to regulate who accesses their cloud environment thanks to its regulatory compliance.
10. What is the difference between traditional data centres and cloud datacenters?
Traditional data centres are more expensive because they have software, heating, and hardware challenges. Cloud computing does not have these issues.
11. How will you protect data during cloud transport?
The best way to protect data is to utilise a virtual private network (VPN). A firewall will also aid in the separation of private and public networks.
12. In cloud computing, what are the three essential functional clouds?
Professional cloud, Personal cloud, and Performance cloud are three essential clouds in cloud computing.
13. What distinguishes cloud computing from traditional data centres?
Since the cost of heating hardware or software, typical data centres are prohibitively expensive. And the majority of the costs are spent on data centre upkeep, which is not the case with cloud computing. In the case of the cloud, data may be simply stored and does not require as much maintenance expense.
14. What is cloud architecture, and how does it work?
Cloud architecture refers to the integration of both components and the subcomponents required for cloud computing. Clients, mobile devices, servers, and storage are all included in the front end and back end platforms. Other than that, there’s a network and cloud-based delivery.
15. What distinguishes cloud architecture from traditional architecture?
The following are the most notable qualities that separate cloud architecture from traditional architecture:
- Traditional architecture cannot scale resources on demand. However, cloud architecture can.
- It also can handle dynamic workloads without failing.
- Finally, cloud architecture includes all of the necessary hardware.
16. What do cloud computing system integrators perform?
Cloud computing system integrators give the strategy for complex processes that are used in the creation of a cloud platform. Integrators, with their experience of data centre construction, are more likely to assist in the development of both public and private cloud networks.
17. What are the different types of data centres used in cloud computing?
For cloud computing, there are primarily two types of data centres: low-density data centres and containerized data centres.
18. What is the difference between encryption and hashing?
To turn readable data into an unreadable format, both encryption and hashing are utilised. The distinction is that encrypted data can be decrypted and converted back to original data, whereas hashed data cannot be converted back to original data.
19. What exactly is a traceroute? What is the purpose of it?
Traceroute is a utility that displays a packet’s journey. It lists all of the locations (mostly routers) through which the packet goes. This is typically used when a packet fails to reach its intended destination. To find the point of failure, use Traceroute to see where the connection stops or breaks.
20. What is the distinction between HIDS and NIDS?
Both HIDS (Host IDS) and NIDS (Network IDS) are Intrusion Detection Systems that have the same goal of detecting intrusions. The only distinction is that HIDS is configured on a specific host or device. It keeps track of a device’s traffic as well as questionable system activity. NIDS, on the other hand, is a networked system. It keeps track of all network devices’ traffic.
21.What are the OSI model’s many layers?
A reference model for how apps communicate over a network is the OSI model. An OSI reference is a set of guidelines for vendors and developers to follow in order for digital communication goods and software applications to work together.
22. How often should patch management be performed?
Patch management should begin as soon as the patch is available. When a patch for Windows is released, it should be applied to all machines within one month. The same is true for network devices; apply the patch as soon as it is available. Patch management should be done correctly.
23. How would you reset a BIOS setup that is password-protected?
BIOS has its own storage mechanism for settings and preferences because it is a pre-boot system. A easy approach to reset is to remove the CMOS battery, which causes the memory that stores the settings to lose power and, as a result, lose its settings.
24. What is an MITM attack and how may it be avoided?
A MITM (Man-in-the-Middle) attack occurs when a hacker inserts himself between two parties’ communications in order to collect information. Assume there is a communication between two parties A and B. The hacker then joins the conversation. In front of A, he impersonates party B, and in front of B, he impersonates party A. Both parties’ data is transmitted to the hacker, who then redirects it to the destination party after stealing the necessary information. While both parties believe they are conversing with one another, they are actually communicating with the hacker.
25. In a LAN, what is port blocking?
Port blocking is the process of preventing users from accessing a set of services on a local area network. Stopping the source from using ports to communicate with the destination node. Because the programme uses ports, ports are restricted to limit access, closing security gaps in the network infrastructure.
26. What are salted hashes?
Salt is a set of random numbers. When a password system is correctly safeguarded, it generates a hash value for the password, a random salt value, and then stores the combined result in its database. This provides protection against dictionary and known hash attacks.
27. What is two-factor authentication (two-factor authentication) and how can it be used on public websites?
“Multi-factor authentication” is an additional layer of protection. Not only does it require a password and username, but it also necessitates something that only that user has on them, such as a piece of information that only they should know or have on hand – such as a physical token. Authenticator apps eliminate the requirement for a verification code to be sent via text, voice, or email.
28. What is Cognitive Cybersecurity, and how does it work?
Cognitive cybersecurity is the use of artificial intelligence (AI) technology to detect risks and secure physical and digital systems based on human mental processes. Data mining, pattern recognition, and natural language processing are used in self-learning security systems to replicate the human brain, although in a high-powered computer model.
29. Print billing is frequently linked to the user’s login in our computing laboratories. People occasionally phone to complain about bills they never received for printing, only to discover that the bills are correct. What conclusions do you draw from this situation? Justify.
They may discover that they had rented their account to a friend who couldn’t remember his or her password, and that the friend was the one who printed. As a result, the charges. It’s also conceivable that they were followed in and their account was used.
This is a problem with public or shared computers in general. Someone else can come in behind you and retrieve what you were doing, use your accounts, and so on if you don’t properly log out of the computer when you leave. Before you go, log out of all accounts, close programmes, and close browser windows.
30. There was a situation that occurred in my computer lab. My friend used their yahoo account in a college computer lab. Before leaving the lab, she double-checked that her account had not been left open. Someone tracked her down and re-entered her account using the same browser. It was then that they began sending emails from it. What do you think the situation is?
Since the first individual most likely did not log out of her account, the new person may simply go to history and access it. Another option is that she logged out but did not delete her internet cache. (To clear sites that the browser has saved for future use, go to the browser menu.)
