There are 64 devices running non-stop. In a period of 48 hours, two of the devices failed. Calculate the Mean Time Between Failures (MTBF) for the Service Level Agreement (SLA). - Correct Answer MTBF (total time/number of failures) (48*64)/2=1536 It will fail in about 1536 hours or 64 days What access security controls are important to consider when managing remote access for network administrators? - Correct Answer Authentication and authorization An attacker used a malicious host with a spoofed physical address to perform cache poisoning and perpetuate an on-path attack.
