Here is the Cheat Sheet for DNSSEC. Recently vulnerabilities in the DNS were discovered that allow an attacker to hijack this process of looking some one up or looking a site up on the Internet using their name. The purpose of the attack is to take control of the session to, for example, send the user to the hijacker's own deceptive web site for account and password collection.

These vulnerabilities have increased interest in introducing a technology called DNS Security Extensions (DNSSEC) to secure this part of the Internet's infrastructure.

Here is the Cheat Sheet for DNS, an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.cloudpacket.com might translate to 104.27.143.238.

The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.

Here is the Cisco FEX Cheat Sheet on Nexus platform, Fabric Extender (FEX for short) is a companion to a Nexus 5K to 9K switch. The FEX, unlike a traditional switch, has no capability to store a forwarding table or run any control plane protocols. It relies on its parent 5K/6K/7K/9K to perform those functions. As the name implies, the FEX “extends” the fabric (ie, the network) out towards the edge devices that require network connectivity.
