Refer to the captured three packets shown in the figure. Which of the following statements is false?
A (Correct): The client initiates the connection using a random source port (50190).
B (Correct): The packets show the TCP three-way handshake (SYN, SYN-ACK, ACK).
C (Incorrect): The client initiates the connection (10.0.12.1), and the server responds (10.0.12.2), so the roles are reversed in this statement.
D (Correct): The handshake packets contain no application-layer data, only TCP control flags.
Thus, the correct answer is C (False Statement).
What is the TPID value defined by IEEE 802.1Q?
TPID (Tag Protocol Identifier) is a field in the VLAN tag that identifies 802.1Q-tagged frames.
The correct TPID value for 802.1Q is 0x8100.
0x9100 (B) is used for Q-in-Q (double tagging).
0x7200 (A) and 0x8200 (D) are incorrect values.
Thus, the correct answer is C (0x8100).
(Which of the following statements about IPv6 anycast addresses are true?)
IPv6 Anycast Address Characteristics:
Option A: True. Packets are delivered to the nearest interface based on routing distance.
Option B: False. Anycast addresses are not designed for load balancing.
Option C: True. Anycast addresses share the same address space as unicast.
Option D: True. Anycast provides redundancy by allowing multiple endpoints to share the same address.
(Network Functions Virtualization (NFV) implements software-based network application deployment.)
NFV Overview:
NFV replaces traditional hardware appliances with software-based solutions that can be deployed on virtualized infrastructure. This allows for flexible, cost-effective, and scalable network application deployment.
Wi-Fi 6 is also known as the IEEE 802.11ax standard.
Detailed
Wi-Fi 6 refers to the IEEE 802.11ax standard, which improves the efficiency, capacity, and performance of wireless networks, especially in dense environments.
