Question 590
A network upgrade at Cedarline Hotels has two requirements: (1) form a modified EUI-64 interface identifier from a 48-bit MAC, and (2) distinguish a public-scope IPv6 unicast destination. Select TWO actions that together satisfy both outcomes.
Explanation
Correct Answers
Correct for outcome (1): Modified EUI-64 expands the 48-bit MAC and flips the U/L bit to form a 64-bit identifier. The other outcome needs its separate action.
Correct for outcome (2): IPv6 global unicast ranges provide global routing scope subject to assigned prefixes and filters. It complements the first required control.
Incorrect Answers
Not selected: Run ip route get with the destination IP is for check the selected route to a destination on Linux. Linux route lookup reveals the chosen outgoing interface and gateway for that address. This is outside the two requested outcomes.
Not selected: Inspect physical cabling, transceivers, and interface counters is for diagnose rising CRC/FCS errors on one access port. Corrupt Ethernet frames commonly indicate physical media, cabling, or signaling faults. This is not one of the two required changes.
Not selected: Run ipconfig /all on the Windows client is for see IPv4 address, mask, gateway and DNS on Windows. Windows ipconfig /all displays detailed TCP/IP adapter configuration. This does not provide either of the two specified controls.
