If the MAC address of an interface is 00E0-FCEF-0FEC, the corresponding EUI-64 address is ( ).
If the MAC address of an interface is 00E0-FCEF-0FEC, the corresponding EUI-64 address is ( ).
To convert a MAC address to an EUI-64 address, the MAC address is split into two halves and 'FFFE' is inserted in the middle. Additionally, the Universal/Local (U/L) bit, which is the seventh bit of the first octet, needs to be toggled. For the MAC address 00E0-FCEF-0FEC, that first octet is 00. When the U/L bit is toggled, this becomes 02. Hence, the correct EUI-64 address is 02E0-FCEF-FFFE-0FEC.
According to several calculators its 2e0:fcff:feef:fec, thus A
Mac address is break in two blocks and in the middle you insert FFFE
Answer is C
Option A is correct
Based on the explanation from the forum below, A is the correct answer. https://community.cisco.com/t5/switching/mac-to-eui-64-conversion/td-p/1432287
B. Local. C. Radius. Explanation: B. Local: Refers to local authentication, where user credentials are stored locally on the router. C. Radius: Refers to authentication using a Remote Authentication Dial-In User Service (RADIUS) server. The router sends authentication requests to a RADIUS server, and the server validates the credentials. Option A (None) and Option D (802.1X$) are not accurate in the context of supported AAA authentication modes on Huawei AR G3 Series routers.
