in multiple inheritance, if some members in parent classes overlap, what classes must be defined as virtual?

Answers

Answer 1

In multiple inheritance, if some memebers of the base classes or parent classes, then the base or parent class must be defined as a virtual class and access into child class as a public virtual class.

In multiple inheritance, sometimes the members of the base classes inherited into multiple classes which create ambiguity or confusion. for example, if a base class A is inherited in child class B, and B class is inherited by C, and class D is inherited by both B and C. Then it makes the ambiguity in accessing the members of class. for example, in this scenario, in class D, B and C both inherited by A and there members function duplicated.

#include <iostream>

using namespace std;

class A {

  public:

  int number;

  showNumber(){

     number = 10;

  }

};

class B : public virtual A {

};

class C : public virtual A {

};

class D : public C, public B {

};

int main(){

  //creating class D object

  D object;

  cout << "Number = " << object.number << endl;

  return 0;

}

The above program print 10.

contiguous allocation of a file is defined by the address of the first block and length (in block units) of the file.T/F

Answers

True. Contiguous allocation of a file is indeed defined by the address of the first block and the length of the file in block units.

In the context of file systems, contiguous allocation is a file allocation method where the file occupies a consecutive set of blocks on the storage medium. The summary statement is accurate in stating that contiguous allocation is defined by the address of the first block and the length of the file in block units.

When a file is stored using contiguous allocation, the file system assigns a starting address, typically the address of the first block, and a length to the file. The starting address represents the location of the first block of the file, and the length denotes the number of contiguous blocks required to store the file. This information is crucial for accessing and managing the file on the storage medium.

By storing a file contiguously, it enables faster access to the file's contents since the blocks are located in close proximity on the storage medium. However, this method can suffer from limitations such as fragmentation when free blocks are not available in a contiguous manner, leading to inefficient utilization of storage space.

What are the benefits of building redundancy into a network? What are the potential issues with building redundancy?

Answers

Answer:

The benefits of building redundancy into a network is the provision of an alternative path for data transmission in the event of a failure of the primary route of data transmission, thereby ensuring the availability of the network and reducing the likelihood of a network failure during the data transmission

Potential issues with building redundancy includes

1) When the broadcast frame generated by a device in a network that has redundancy is forwarded by another device within the network that has no loop avoidance algorithm or schematics, the network switches will keep broadcasting the same data repeatedly such that the network bandwidth is consumed and potentially leading to a shut down of the network

2) More than one copy of a frame may be received by a device in the network with redundancy

3) Instability of the MAC address table, when the switch makes entry into the MAC table for a frame generated from a particular source but however received from more than one link

Explanation:

Answer:

Network redundancy can be defined as the process of adding the network device, along with a line of communication to provide network availability. Benefits of building redundancy into a network: It decreases the risk of network failure. If one server fails to transfer the information, then the backup server will take the charge to help in continuing the communication. Potential issues with building redundancy: Denial of service and cyber attacks are the threats to network. Without the use of backup system the one point failure can disrupt the entire system.

Show that the relation R consisting of all pairs (x, y) such that x and y are bit strings of length three or more that agree except perhaps in their first three bits is an equivalence relation on the set of all bit strings of length three or more

Answers

To show that the relation R consisting of all pairs (x, y) such that x and y are bit strings of length three or more that agree except perhaps in their first three bits is an equivalence relation, we need to demonstrate that R satisfies the three properties of equivalence relations: reflexivity, symmetry, and transitivity.

1. Reflexivity: A relation R is reflexive if for every element x, (x, x) belongs to R. Since the bit strings x and y agree with themselves, the first three bits of x and y can be the same or different, but the rest of the bits will always agree. Therefore, R is reflexive.

2. Symmetry: A relation R is symmetric if for every pair (x, y) in R, the pair (y, x) is also in R. If the bit strings x and y have the same bits except for possibly the first three, then switching the positions of x and y does not change the fact that they still agree except for their first three bits. Thus, R is symmetric.

3. Transitivity: A relation R is transitive if for every pair (x, y) and (y, z) in R, the pair (x, z) is also in R. If x and y agree except for possibly their first three bits and y and z agree except for possibly their first three bits, then x and z will also agree except for possibly their first three bits. Any disagreements between x and z would have to stem from the first three bits since they both agree with y beyond that point. Therefore, R is transitive.

Since the relation R satisfies the properties of reflexivity, symmetry, and transitivity, we can conclude that R is an equivalence relation on the set of all bit strings of length three or more.

Answers

The vulnerabilities associated with route security are route injection, Source routing, Software exploits.

What are the vulnerabilities associated with route security?

Spoofed routing information (route injection)—Routing protocols that have no or weak authentication are vulnerable to route table poisoning. This can mean that traffic is misdirected to a monitoring port (sniffing), sent to a blackhole (nonexistent address), or continuously looped around the network, causing DoS.

Source routing—This uses an option in the IP header to pre-determine the route a packet will take through the network (strict) or "waypoints" that it must pass through (loose). This can be used maliciously to spoof IP addresses and bypass router/firewall filters. Routers can be configured to block source routed packets.

Software exploits in the underlying operating system—Hardware routers (and switches) have an embedded operating system. For example, Cisco devices typically use the Internetwork Operating System (IOS). Something like IOS suffers from fewer exploitable vulnerabilities than full network operating systems. It has a reduced attack surface compared to a computer OS, such as Windows.
