   A manufacturing plant uses 125 kHz RFID tags on pallets to track inventory through a conveyor system. A competitor wants to disrupt the plant's operations without being detected. The plant's security team must choose a defense that does not interfere with normal operations. Which attack is hardest to detect and most likely to cause intermittent disruption?

   • AA continuous-wave jammer tuned to 125 kHz placed near the conveyor
   • BA device that reconfigures the reader's firmware to ignore certain tag IDs
   • CA device that transmits a strong LF pulse only when a tag enters the reader field
   • DA device that physically shields the reader antenna with a metal plate

   A pet adoption center uses 134.2 kHz RFID implants to identify animals. The center is concerned that an attacker could skim the implant data and clone it to impersonate an animal. The implants are read-only and contain only a unique ID. Which characteristic of the LF RFID system makes it vulnerable to this attack?

   • AThe LF signal has a long read range of up to 10 meters
   • BThe implant requires a battery to transmit its ID, which makes it easier to intercept
   • CThe LF signal is easily blocked by water, which prevents the implant from being read
   • DThe implant's unique ID is transmitted in clear text and can be captured with a receiver
