What Is Network Hardware? Definition, Architecture, Challenges, and Best Practices?

Answer:

              consumes a lot of bandwidth as many computers might not need to receive the broadcasted data. The hub could be useful in linking a few gaming consoles in a local multiplayer game via a wired or wireless LAN.

         Bridges: A bridge connects two separate LAN networks. It scans for the receiving device before sending a message. This implies that it avoids unnecessary data transfers if the receiving device is not there. Moreover, it also checks to see whether the receiving device has already received the message. These practices improve the overall performance of the network.

You have been hired by a manufacturing company that has had its network in place for many years. They currently have 50 computers connected to 10 Mbps hubs. You’ve been asked to upgrade the network. This long- overdue upgrade is necessary because of poor network response time caused by a lot of collisions occurring during long file transfers between clients and servers. How do you recommend upgrading this network? What interconnecting devices will you use, and what benefit will you get from using these devices? Write a short memo describing the upgrade

A security architect is reviewing the following proposed corporate firewall architecture and configuration:

Both firewalls are stateful and provide Layer 7 filtering and routing. The company has the following requirements:

✑ Web servers must receive all updates via HTTP/S from the corporate network.

Web servers should not initiate communication with the Internet.

✑ Web servers should only connect to preapproved corporate database servers.

✑ Employees' computing devices should only connect to web services over ports 80 and 443.

Which of the following should the architect recommend to ensure all requirements are met in the MOST secure manner? (Choose two.)

A.  Add the following to Firewall_A: 15 PERMIT FROM 10.0.0.0/16 TO 0.0.0.0/0 TCP 80,443

B.  Add the following to Firewall_A: 15 PERMIT FROM 192.168.1.0/24 TO 0.0.0.0 TCP 80,443

C.  Add the following to Firewall_A: 15 PERMIT FROM 10.0.0.0/16 TO 0.0.0.0/0 TCP/UDP 0-65535

D.  Add the following to Firewall_B: 15 PERMIT FROM 0.0.0.0/0 TO 10.0.0.0/16 TCP/UDP 0-65535

E.  Add the following to Firewall_B: 15 PERMIT FROM 10.0.0.0/16 TO 0.0.0.0 TCP/UDP 0-65535

F.  Add the following to Firewall_B: 15 PERMIT FROM 192.168.1.0/24 TO 10.0.2.10/32 TCP 80,443

@ Shilpa is saying C and E 

@ Others are saying  A and D 

If you only sure the answer then only response else no need
