The given statement "DBA_USERS contains comments on all tables in an Oracle database" is false because DBA_USERS contains information about database users, not table comments.

DBA_USERS is a system table in Oracle that contains information about all users in the database, such as their username, password, and account status. It does not contain information about table comments. However, Oracle does provide a feature for adding comments to tables and other database objects using the COMMENT command.

These comments can be viewed in the ALL_TAB_COMMENTS or DBA_TAB_COMMENTS tables. The ALL_TAB_COMMENTS table contains comments on all tables accessible to the current user, while the DBA_TAB_COMMENTS table contains comments on all tables in the database.

Therefore, to view comments on all tables in an Oracle database, you would query the DBA_TAB_COMMENTS table, not the DBA_USERS table.

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.

The correct answer is option 3: 8 subnets, 30 hosts per subnet. This means that the network can be divided into 8 subnets, each containing up to 30 hosts.

The maximum number of subnets and hosts per subnet for the 192.168.50.247 255.255.255.224 network can be determined by looking at the subnet mask, which is represented by 255.255.255.224. This subnet mask indicates that the network uses 27 bits for the network portion and 5 bits for the host portion.

To calculate the number of subnets, we need to determine the number of bits that are used for the network portion of the address. In this case, 27 bits are used, which means that there are 2⁵ or 32 possible subnets. However, two of these subnets are reserved for network and broadcast addresses, leaving 30 usable subnets.

To calculate the number of hosts per subnet, we need to determine the number of bits that are used for the host portion of the address. In this case, 5 bits are used, which means that there are 2⁵⁻² or 30 possible hosts per subnet. The -2 is because the first and last addresses in each subnet are reserved for the network and broadcast addresses.

So, the correct option is 3). This information is important for network administrators who need to allocate IP addresses and manage network traffic effectively.

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.
