The incorrect statement about the Domain Name System (DNS) is: c) It is maintained by a relational database system that uses the peer-to-peer networking model.
The DNS is not maintained by a relational database system that uses the peer-to-peer networking model.
The correct statements about DNS are:
a. It translates domain names to their numerical IP addresses. DNS acts as a translation system that converts human-readable domain names (like example.com) into their corresponding IP addresses (such as 192.0.2.1).
b. It is known as the internet's primary directory service. DNS serves as a distributed directory service that stores and manages domain name records, allowing users to access websites and services using domain names.
d. It consists of a tree of domain names. DNS operates in a hierarchical structure, forming a tree-like domain name system. The top-level domain (TLD) sits at the root of the tree, followed by second-level domains, subdomains, and individual hostnames.
It's important to note that DNS typically uses a distributed database system with a hierarchical design rather than a relational database system. Additionally, DNS relies on a client-server model where DNS resolvers (clients) send queries to DNS servers for resolution, rather than employing a peer-to-peer networking model.

For each of the four ANSI levels of query isolation, discuss the impact on recovery. What prop erties must a transaction schedule have to ensure recovery works correctly
ANSI defines four levels of query isolation, each with its own properties that affect the impact on recovery: Read Uncommitted, Read Committed, Repeatable Read.
Serializable: This level ensures that concurrent transactions behave as if they were executed serially, preventing any interleaving of transactions. In the event of a failure, the recovery process must ensure that all transactions are committed or rolled back properly, to prevent inconsistent data from being read. To ensure recovery works correctly, a transaction schedule must have the following properties: Atomicity: Each transaction should be treated as a single unit of work, meaning that either all of its operations are executed, or none of them are. This ensures that transactions can be rolled back if necessary, without leaving the database in an inconsistent state. Consistency: Each transaction should maintain the consistency of the database, meaning that it should start and end in a consistent state. This ensures that all transactions can be committed, without leaving the database in an inconsistent state. Isolation: Each transaction should execute independently of other transactions, meaning that they should not interfere with each other. This ensures that each transaction can be rolled back or committed independently, without affecting the consistency of the database. Durability: Each committed transaction should persist, even in the event of a failure, to ensure that the database can be restored to a consistent state. This means that the recovery process must ensure that all committed transactions are stored safely, and can be recovered in case of failure.

12. What is a network baseline, and when is it established?
A network baseline refers to a snapshot of a network's performance, usage, and behavior at a specific point in time.
This snapshot is established by monitoring the network over a period of time to gather data on network traffic patterns, bandwidth utilization, application usage, and other metrics. Once this data is collected and analyzed, a network baseline is established. This baseline serves as a reference point for future network performance analysis and troubleshooting. It also helps network administrators to identify and respond to anomalies and deviations from the established baseline.
A network baseline is a representation of a network's typical behavior across time. It serves as a benchmark for capacity, performance, and security monitoring. Network traffic, bandwidth use, protocol distribution, and other important information are recorded in a baseline. Network administrators can recognise trends, spot anomalous behaviour, and fix problems by analysing this data. Additionally, a baseline can be used to spot potential security risks like unusual traffic patterns or unauthorised access attempts. In order to undertake proactive network monitoring and maintenance, establishing a baseline is essential since it serves as the basis for performance optimisation, capacity planning, and incident response.

T/F. Combining a table with itself results in a faster query.
The statement" Combining a table with itself results in a faster query" is False because Combining a table with itself, also known as a self-join, can actually slow down a query because it requires additional processing power and can create duplicate rows.
A self-join is used when you want to combine rows from a table with other rows from the same table based on a specified condition.
This operation requires accessing and comparing the rows within the same table, which can involve a significant amount of data processing.
The performance of a self-join depends on various factors such as the size of the table, the presence of indexes, the join condition complexity, and the underlying database system's optimization capabilities.
In some cases, a self-join can be optimized efficiently by the database engine, but it's not a guarantee.
To improve the performance of a self-join, it's important to ensure that appropriate indexes are in place, the join condition is optimized, and the underlying database engine is properly configured.

Unlike a traditional IDS, an IPS must sit ____________________ (in the flow of traffic) to be able to interact effectively with the network traffic.
Unlike a traditional IDS, an IPS must sit "in-line" (in the flow of traffic) to be able to interact effectively with the network traffic.Explanation:
Intrusion Prevention Systems (IPS) are designed to detect and block network-based attacks in real-time. Unlike an Intrusion Detection System (IDS), which only passively monitors network traffic and raises alerts when it detects suspicious activity, an IPS is positioned directly in the path of network traffic, allowing it to actively inspect and block malicious traffic in real-time.This "in-line" positioning is crucial for the effectiveness of an IPS because it enables it to intercept and block malicious traffic before it can reach its intended target. This is particularly important in today's fast-paced threat landscape, where attackers are constantly developing new and sophisticated techniques to evade detection and infiltrate networks.By sitting in-line, an IPS is able to inspect every packet of data passing through the network, in real-time, and take immediate action to block any suspicious or malicious traffic. This helps organizations to better protect their network assets and data from potential cyber threats.
