What are two reasons for choosing Transport Layer Security (TLS) over IP Security (IPsec) encryption? (Choose two.) IPsec encrypts the IP packet, resulting in lesser application-level security. IPsec is less efficient than TLS, and in general not supported on mobile devices. IPsec requires dedicated software installed on client hosts. TLS can be used for encrypting traffic to public websites. TLS decryption can be easily accelerated in hardware. correct answers IPsec requires dedicated software installed on client hosts TLS can be used for encrypting traffic to public websites.

(Choose two.) crossover rollover serial straight-through USB correct answers rollover USB A device has been assigned an IPv6 address through the Stateless Address Autoconfiguration (SLAAC) process. Which three statements about SLAAC are correct? (Choose three.) It generates link-local addresses. It generates global unicast IPv6 addresses. It must be used in combination with a DHCPv6 server. It relies on ICMPv6 router advertisements. It requires a device to use the EUI-64 format in the process. It relies on a DHCPv6 server for duplicate address detection (DAD). correct answers It generates link-local addresses. It generates global unicast IPv6 addresses. It relies on ICMPv6 router advertisements.
