Select the true statements about sockets. (Select two answers)

Show Suggested Answer Hide Answer
Suggested Answer: A, D

1. A socket is a connection point that enables a two-way communication between programs running in a network.

This statement is true because a socket is a software structure that serves as an endpoint for sending and receiving data across a network. A socket is defined by an application programming interface (API) for the networking architecture, such as TCP/IP.A socket can be used to establish a communication channel between two programs running on the same or different network nodes12.

2. A socket is always the secure means by which computers on a network can safely communicate, without the risk of exposure to an attack.

This statement is false because a socket by itself does not provide any security or encryption for the data transmitted over the network. A socket can be vulnerable to various types of attacks, such as eavesdropping, spoofing, hijacking, or denial-of-service.To ensure secure communication, a socket can use additional protocols or mechanisms, such as SSL/TLS, SSH, VPN, or firewall3.

3. A socket is a connection point that enables a one-way communication only between remote processes.

This statement is false because a socket can enable both one-way and two-way communication between processes running on the same or different network nodes. A socket can be used for connection-oriented or connectionless communication, depending on the type of protocol used.For example, TCP is a connection-oriented protocol that provides reliable and bidirectional data transfer, while UDP is a connectionless protocol that provides unreliable and unidirectional data transfer12.

4. A socket can be used to establish a communication endpoint for processes running on the same or different machines.

This statement is true because a socket can be used for inter-process communication (IPC) within a single machine or across different machines on a network.A socket can use different types of addresses to identify the processes involved in the communication, such as IP address and port number for network sockets, or file name or path for Unix domain sockets12.

C seems wrong to me since sockets are meant for two-way communication, but I can't recall all the details.

I practiced a similar question, and I think D is correct too because sockets can connect processes on different machines.

The key here is understanding the fundamental nature of sockets as a communication mechanism. A and D seem to capture that best, so those are my picks.

I'm a little confused about the one-way communication part in C. Sockets are supposed to be two-way, right? I'll have to double-check that.

Okay, let's see. A socket is definitely a connection point, and it can be used for communication between processes on the same or different machines. I'll go with A and D.

Hmm, I'm a bit unsure about the security aspect. Is B really true? I'll have to think that one through more carefully.

I'm not too familiar with Cisco ACI, so this is a bit tricky for me. I'd probably start by reviewing the documentation on access control policies in the APIC to get a better understanding of where to configure this type of restriction.

I'm not entirely sure how to approach this. The profit matrix part is throwing me off a bit. I'll need to re-read the question carefully and make sure I understand what they're asking for.
