which of the following is a method that allows you to connect a private network to the internet without obtaining registered addresses for every host? answer nat eigrp ospf bgp
Answer:
The method that allows connecting a private network to the internet without obtaining registered addresses for every host is Network Address Translation (NAT). NAT is used to map the private IP addresses on a local area network (LAN) to one or more public IP addresses that are routable on the internet. This way, multiple hosts on the LAN can share a single public IP address, reducing the need for registered addresses for each host. NAT operates by modifying the IP headers of packets that pass through a network gateway, translating the private IP addresses to the public IP address for internet communication.

What is the main difference between array and vector type in C++?
The main difference between array and vector types in C++ is that arrays have a fixed size and require manual memory management, whereas vectors are dynamic and automatically manage their own memory allocation and deallocation.
In C++, both arrays and vectors are used to store a collection of elements of the same data type. However, there are some key differences between the two: Dynamic vs. Static: An array has a fixed size and cannot be resized during runtime, whereas a vector can dynamically grow or shrink in size as elements are added or removed. Memory Management: When an array is created, a block of contiguous memory is allocated for it, and the programmer is responsible for managing the memory allocation and deallocation. In contrast, a vector automatically manages its own memory allocation and deallocation, so the programmer does not need to worry about it. Access: Elements in an array are accessed using an index, which must be within the range of the array. Vectors provide random access to their elements, and also provide functions for iterating through them. Functions: Vectors provide many built-in functions such as push_back(), pop_back(), size(), and capacity() for managing and manipulating the collection of elements. Arrays do not have built-in functions like vectors do.

evaluate the use of trusted media access control (mac) addresses as one method of network security.
Answer:
Trusted Media Access Control (MAC) addresses are one method of network security that can be used to control access to a network by only allowing devices with known MAC addresses to connect. The MAC address is a unique identifier assigned to each network interface controller (NIC) on a device, which means that by only allowing known MAC addresses to connect, unauthorized devices are prevented from accessing the network.
While this method of network security can be effective, it does have some limitations. First, MAC addresses can be spoofed, which means that a device can be configured to present a different MAC address than its actual one. This makes it possible for an unauthorized device to bypass security measures and gain access to the network. Additionally, MAC addresses are only relevant within a single local network, which means that they do not provide security when devices are accessing the network remotely or over the internet.
Another limitation of using MAC addresses for network security is that managing the list of allowed MAC addresses can be time-consuming and complex, especially for larger networks with a high number of devices. It may also be challenging to ensure that the list of allowed MAC addresses is kept up-to-date, as devices may be added or removed from the network frequently.
In summary, while Trusted MAC addresses can be a useful method of network security, it should not be the sole method used, as it has some significant limitations. It is best used as part of a multi-layered approach to network security that includes other methods such as firewalls, intrusion detection and prevention systems, and authentication protocols.

TRUE/FALSE. In general, SCAN disk head scheduling will involve less movement of the disk heads than C-SCAN disk head scheduling.
The statement is true because in C-SCAN disk head scheduling, the disk arm moves in only one direction, servicing all requests in its path before returning to the beginning of the disk and starting again.
This ensures that requests located near the beginning of the disk are serviced more frequently, reducing the amount of time required to access data and leading to less movement of the disk heads.
In contrast, in SCAN disk head scheduling, the disk arm moves back and forth across the disk, processing all requests in its path in a single direction and then reversing direction when it reaches the end of the disk. This can result in longer access times for requests that are located far from the current position of the disk arm, and can lead to more movement of the disk heads.

Which technology uses parity/strip
A) Deduplication
B) Compression
C) Erasure coding
Erasure coding is a technology that uses parity and striping to ensure data reliability and fault tolerance in storage systems. The correct answer is C) Erasure Coding.
It works by dividing data into fragments, encoding and expanding these fragments with redundant pieces of information, and then storing them across different disks or storage nodes. This method allows for the recovery of lost or corrupted data by using the remaining intact fragments and the parity data, which serves as an error-correction mechanism.
In comparison, deduplication (A) and compression (B) are both data reduction techniques aimed at saving storage space. Deduplication involves eliminating duplicate copies of data, while compression reduces the size of data by encoding it more efficiently. Neither of these technologies relies on parity or striping for their primary function. Hence, C is the correct option.

208. Implement a Trie (Prefix Tree)
Implement a trie with insert, search, and startsWith methods.
Note:
You may assume that all inputs are consist of lowercase letters a-z.
All inputs are guaranteed to be non-empty strings.
A trie, also known as a prefix tree, is a tree data structure that is commonly used for efficiently storing and searching for strings. It supports three main operations: inserting a string, searching for a string, and finding all strings that start with a given prefix.
A trie is a type of tree data structure where each node represents a prefix of one or more strings. The root node represents the empty string, and each subsequent node represents a prefix of the strings that are stored in the trie. Each node may have multiple children, one for each possible next character in the strings.
For example, if the trie contains the strings "cat", "car", and "cut", then the root node would have children for "c", "a", and "u", and the "c" child would have children for "a" and "u".
To insert a string into the trie, we start at the root node and traverse down the tree, adding new nodes as necessary to represent the prefix of the string that is not already in the trie. Once we reach the end of the string, we mark the final node as a leaf node to indicate that the string is stored in the trie.
To search for a string in the trie, we start at the root node and traverse down the tree, following the path that corresponds to the characters in the string. If we reach a leaf node, then the string is in the trie; otherwise, the string is not in the trie.
To find all strings that start with a given prefix, we start at the root node and traverse down the tree, following the path that corresponds to the characters in the prefix. Then, we perform a depth-first search to find all of the leaf nodes in the subtree rooted at the prefix node, and return the strings that correspond to those nodes.
