Which of the following commands in Windows always changes the current directory to the root directory?

Your company's external firewall starts sending you alerts about receiving bad traffic from the Internet, packets that it says are coming from a host with the IP address 10.12.25.205. What is the term for these bad packets?

  • Ketchup packets

Which of the following commands in Windows always changes the current directory to the root directory?

EXPLANATION

A martian packet is an IP packet that specifies a source or destination address that is reserved for special-use by the Internet Assigned Numbers Authority (IANA). If seen on the public internet, these packets cannot actually originate as claimed, or be delivered.  (All IPv4 addresses with "10" in the first octet are considered private internal addresses and should never be seen on Internet traffic.)
Martian packets commonly arise from IP address spoofing in denial-of-service attacks, but can also arise from network equipment malfunction or misconfiguration of a host.

The name is derived from the idea of receiving packets from Mars, a place from which packets clearly cannot originate.

A Xmas tree packet is a packet with every single option set for whatever protocol is in use. The term derives from a fanciful image of each little option bit in a header being represented by a different-colored light bulb, all turned on, as in, "the packet was lit up like a Christmas tree."  (These are also used in denial-of-service attacks.)
