10+ Solution Advisor Interview Questions and Answers

Multi VPCs can be connected using VPC peering or VPN connections.

• VPC peering allows direct communication between VPCs using private IP addresses.

• VPN connections can be established between VPCs using virtual private gateways.

• Routing tables need to be updated to allow traffic flow between VPCs.

• Security groups and network ACLs need to be configured to allow traffic between VPCs.

• AWS Transit Gateway can also be used to connect multiple VPCs.

• VPC peering and VPN connections have lim...read more

You can refer to other measures like ROC-AUC, precision-recall curve, F1 score, etc.

• ROC-AUC: Receiver Operating Characteristic - Area Under the Curve

• Precision-recall curve: Trade-off between precision and recall

• F1 score: Harmonic mean of precision and recall

Parameterized queries can prevent SQL injection attacks.

• Parameterized queries use placeholders for user input, preventing malicious SQL code injection.

• They are more secure than concatenating user input into SQL statements.

• Example: SELECT * FROM users WHERE username = ? AND password = ?

• The question marks are replaced with user input, preventing SQL injection.

Exploiting a JBoss based application

• Exploit known vulnerabilities in JBoss and its components

• Use brute force attacks to guess weak passwords

• Perform SQL injection attacks to gain access to the database

• Use cross-site scripting (XSS) attacks to inject malicious code

• Exploit misconfigured security settings

• Use social engineering to trick users into revealing sensitive information

• Perform man-in-the-middle attacks to intercept and modify network traffic

• Use remote code execution (RCE)...read more

Local and global variables are used in programming to store data values.

• Local variables are declared within a function and can only be accessed within that function.

• Global variables are declared outside of any function and can be accessed from any part of the program.

• Local variables have a limited scope while global variables have a wider scope.

• Example of local variable: int x = 5; Example of global variable: int y = 10; outside of any function.

• Local variables are destroyed w...read more

ICMP does not have a port number.

• ICMP is a protocol that operates at the network layer of the OSI model.

• It is used for error reporting, network congestion control, and other purposes.

• Unlike TCP and UDP, ICMP does not have a port number.

• Instead, it uses message types and codes to communicate information.

LFI, RFI, and Path Traversal are all types of web application vulnerabilities.

• LFI (Local File Inclusion) is a vulnerability that allows an attacker to include files on a server through the web application.

• RFI (Remote File Inclusion) is a vulnerability that allows an attacker to include files from a remote server through the web application.

• Path Traversal is a vulnerability that allows an attacker to access files outside of the web application's root directory.

• All three vulner...read more

Identity and access management is a framework of policies and technologies that ensure the right individuals have access to the right resources at the right times.

• It involves managing user identities, roles, and permissions within an organization.

• It includes processes such as authentication, authorization, and auditing.

• Examples of identity and access management tools include Active Directory, Okta, and OneLogin.

A bank balance sheet consists of assets, liabilities, and equity.

• Assets include cash, loans, investments, and property.

• Liabilities include deposits, loans, and other debts owed by the bank.

• Equity represents the bank's net worth and includes retained earnings and shareholder investments.

• The balance sheet must balance, with assets equaling liabilities plus equity.

Assumptions of linear regression include linearity, independence, homoscedasticity, and normality.

• Linearity: The relationship between the independent and dependent variables is linear.

• Independence: The residuals are independent of each other.

• Homoscedasticity: The variance of the residuals is constant across all levels of the independent variables.

• Normality: The residuals are normally distributed.

• Outliers and influential points can affect the assumptions.

OWASP Top 10 attacks are common web application vulnerabilities.

• Injection

• Broken Authentication

• Sensitive Data Exposure

• XML External Entities (XXE)

• Broken Access Control

• Security Misconfiguration

• Cross-Site Scripting (XSS)

• Insecure Deserialization

• Using Components with Known Vulnerabilities

• Insufficient Logging and Monitoring

Pipe financing is a common method of raising capital in SPAC transactions.

• Pipe financing involves selling shares to institutional investors at a discounted price.

• This allows the SPAC to raise additional capital to fund the merger or acquisition.

• Pipe investors typically receive warrants or other incentives to participate.

• Pipe financing can be a faster and more efficient way to raise capital than traditional IPOs.

• However, it can also dilute the value of existing shares and lead...read more

XXE Attack is an XML External Entity attack that exploits the vulnerability of parsing XML input.

• XXE Attack is a type of attack that targets applications that parse XML input.

• It allows an attacker to read files on the server, execute remote code, or perform denial of service attacks.

• The attack occurs when an application processes XML input that contains a reference to an external entity.

• By manipulating the external entity reference, an attacker can access sensitive files or e...read more
