✍️ Sample CompTIA Cloud+ Questions & Answers
1. What is the likely cause if a cloud-based database stops responding during a query?
Deadlocks can occur when two or more processes compete for the same resources, causing the database to hang.
2. What is the CIDR notation for a subnet that provides exactly 254 usable host addresses?
A /24 subnet provides 256 total addresses (2^8), with 254 usable host addresses after reserving the network address and broadcast address.
3. Which routing protocol is standard for exchanging routes between autonomous systems in hybrid cloud and internet environments?
Border Gateway Protocol (BGP) is the standard inter-AS routing protocol used on the internet and in hybrid cloud connections such as Direct Connect and ExpressRoute.
4. A company experiences intermittent connectivity between their on-premises network and a cloud VPC. The VPN tunnel status shows as active. What should the engineer check NEXT?
An active tunnel status confirms the VPN is up, but intermittent connectivity often indicates routing issues — verifying BGP tables and route propagation is the correct next diagnostic step.
5. What is a common method for securing data in transit?
Transport Layer Security (TLS) encryption is a common and highly effective method for securing data in transit across networks, including the internet. TLS establishes an encrypted connection between a client and a server, ensuring the confidentiality and integrity of the data exchanged. This protocol protects information from eavesdropping, tampering, and message forgery, making it crucial for secure communication.
6. Which of the following best describes data encryption?
Data encryption is the practice of converting data into an unreadable format, known as ciphertext, using an algorithm and an encryption key. This process prevents unauthorized access by rendering the data unintelligible to anyone without the correct decryption key. It is a fundamental security measure for protecting sensitive information both at rest and in transit.
