Setting up a DMZ with two firewalls has its own advantages. The biggest advantage that you can do load balancing. A topology with two firewalls also helps in protecting internal services on the LAN from denial of the service attacks on the firewall’s perimeter.
What is one advantage of setting up a DMZ in firewalls?
What is one advantage of setting up a DMZ with two firewalls? Explanation: DMZ stands for De-Militarized Zone.

What is an advantage of DNS caching?
DNS caching allows any DNS server or client to locally store the DNS records and re-use them in the future – eliminating the need for new DNS queries.

What advantages do you have with running your own DNS infrastructure?Faster servers compared to the ISP server so requests get processed faster and more smoothly. More reliable servers with better uptime. Geographically closer servers for a closer connection and therefore faster speeds. Options for parental control, such as with OpenDNS.
Article first time published onWhat is a dual firewall?
A dual firewall topology is similar to an industrial process control system 1oo2 voting scheme in that both firewalls must agree that a received packet does not pose a security risk (conditions are safe) or the packet is denied and not permitted to be passed to the protected network.
Why do we need two firewalls?
Multiple firewalls are most commonly used to segregate networks of different sensitivity levels. Universities, for example, commonly use a series of layered firewalls to provide different zones of security for various types of users.
Should I have 2 firewalls?

What are the advantages and disadvantages of implementing a workgroup network vs a domain network?
The complexity enhances when we increase the number of workgroup computers. Security: A domain has very advanced security due to centralized control. On the other hand, a workgroup is very less secure due to no centralized access control. Data Recovery: Data can be recovered in a domain from the centralized storage.
What do you mean by DNS caching how it works?
A DNS Cache works by temporarily storing the results of recently browsed websites’ DNS queries, or other FQDNs, on a local file for faster retrieval. … Upon generating this historical report, I found that a baseline for DNS lookup is around 50 milliseconds, with peaks between 150 and 200 milliseconds.
What is local DNS caching?
DNS cache refers to the temporary storage of information about previous DNS lookups on a machine’s OS or web browser. Keeping a local copy of a DNS lookup allows your OS or browser to quickly retrieve it and thus a website’s URL can be resolved to its corresponding IP much more efficiently.
Is local DNS caching good?
Local DNS Caching DNS turns domain names into IP addresses—similar to how phone books used to map business names to phone numbers. Local DNS caching stores this information at the network-level, speeding up page loads and providing a faster internet experience.
