![]() Identify which of the services below uses both TCP and UDP ports. Unlike a network hub, which is a single collision domain for all ports, each port on a Layer 2 switch is a separate collision domain. No matter how it’s configured, a single switch port is considered what?ĬORRECT ANSWER – A separate collision domain More information on Ethernet frames can be found on Firewall.cx’s Ethernet frame analysis page. If the FCS values don’t match, then the host assumes the frame has an error or is corrupt and, therefore, discards it. If the FCS values match, the frame has arrived without any error. The receiving host generates its own FCS value for every frame received and then compares it with the FCS included in the frame. Every Ethernet frame includes the frame check sequence (FCS) or cyclic redundancy check value that is calculated by the host that sent the frame. The data-link layer is responsible for checking each received frame for errors. Which OSI layer checks frames for errors? Host A receives a frame and discards it after determining it is corrupt. Each of these states discards all frames and isn’t actively learning the media access control (MAC) addresses of connected switches and devices. The reason for the combination is because a port in a disabled, blocking or listening state doesn’t differ from an STP topology perspective. RSTP combines the disabled, blocking and listening states into a single port state known as discarding. ![]() Rapid Spanning Tree Protocol (RSTP) defines three port states, compared with 802.1D STP’s five states. Which Rapid Spanning Tree Protocol port state is a combination of standard 802.1D STP’s disabled, blocking and listening states? 4.4 (32 ratings) 0 lectures, hours All Levels QUIZ QUESTION 1 The practice questions are in no particular order and provide a realistic example of what you should expect.ĬISCO CCNA 200-301 Practice Test (Exam questions) ( Udemy ) This exam questions checks your knowledge in networking and helps you to pass the exam CCNA 200-301. This CCNA practice test covers the appropriate range of topics you can expect when taking the CCNA Routing and Switching exam. If you’ve been studying for your CCNA using the version 3.0 study materials, it is highly advisable you take the older 200-125 exam while you still can. In 2019, Cisco announced a new CCNA Routing and Switching exam. Our updated CCNA practice test has been redesigned to reflect the Cisco CCNA Routing and Switching requirements. Instead, it takes a true in-depth understanding of network fundamentals and network security technologies covered in the CCNA material as outlined by Cisco. With 20 questions.Īchieving your Cisco Certified Networking Associate, or CCNA, certification requires more than just studying.
