Which letter represents the hexadecimal value of the decimal number 15?

• F
• X
• G
• A

A PC is configured with both an IPv4 and IPv6 address on the same network adapter. What IPv4 and IPv6 coexistence strategy is implemented on the PC?

• Dual-stack
• Mixed-stack
• Single-stack
• Hybrid-stack

What are two methods that can be used to shorten the IPv6 address notation? (Choose two.)

• • use of a double colon (::) to represent a string of all zero hextets

• • omit all leading zeros from all hextets in the address

• • remove all trailing zeros contained in the IPv6 address

• • use double colons to represent a string of the same non-zero value

Which network migration technique encapsulates IPv6 packets inside IPv4 packets to carry them over IPv4 network infrastructures?

• • encapsulation

• • translation

• • dual-stack

• • tunneling

What does a double colon (::) represent in an IPv6 address notation?

• • a continuous string of one or more hextets that contain only zeros

• • at least eight occurrences of the same non-zero value

• • the boundary between the network portion and the host portion of the address

• • the beginning of the MAC address assigned to the IPv6 device

IPv6 increases the IP address size from 32 bits to how many bits?

• 512
• 256
• 128
• 64

Which technology enables devices in an IPv6-only network to communicate with devices in an IPv4-only network?

• • DHCP

• NAT64

• tunneling

• IPv4 transition mechanisms

Which IPv6 address notation is valid?

• 2001:0db8::8a2e:0370:7335
• • ABCD:160D::4GAB:FFAB

• • 2001:0DB8::ABCD::1234

• • 2001:DB8:0:1111::200

Answer explanation

Explanation: IPv6 addresses are represented by 32 hexadecimal digits (0-9, A-F). The size of the notation can be reduced by eliminating leading zeroes in any hextet and by replacing a single, contiguous string of hextets containing all zeroes with a double colon, which can only be used one time.
