Question 1 of 36

The IP packet has a special field to mark the QoS. For example, the last 6 bits in the ToS field of an IPv4 packet mark the DSCP value.

    Correct Answer: A

    The statement is true. The last 6 bits in the ToS (Type of Service) field of an IPv4 packet indeed mark the DSCP (Differentiated Services Code Point) value, which is used for QoS (Quality of Service) marking.

Question 2 of 36

Which of the following statements about the device state change is correct after failure in the intermediate link for transmitting VRRP heartbeats?

    Correct Answer: A

    In VRRP (Virtual Router Redundancy Protocol), the master device maintains the virtual IP address and continues forwarding packets unless it fails. When the intermediate link for transmitting VRRP heartbeats fails, the master device does not immediately change its state because it does not receive heartbeat signals from the slave device. Consequently, the master device continues to remain the master. Additionally, the slave device will not receive heartbeat signals from the master and might assume that the master has failed, potentially taking over as the master. However, they do not both enter the Master, Slave, or Initial state simultaneously. Thus, the status of the master and slave devices remains unchanged.

Question 3 of 36

IP QoS models include: (Choose three.)

    Correct Answer: ABC

    IP Quality of Service (QoS) models include Best-Effort, Integrated Service (IntServ), and Differentiated Service (DiffServ). Best-Effort is the default service model for the Internet, where all packets receive the same priority. Integrated Service is a model that provides end-to-end QoS guarantees in IP networks by reserving resources for specific flows. Differentiated Service is a scalable QoS model that differentiates traffic by classifying and managing it based on predefined policies. FIFO Service is not considered a QoS model.

Question 4 of 36

A VRRP virtual router can have one or more IP addresses.

    Correct Answer: A

    A VRRP virtual router can indeed have one or more IP addresses. This is a key feature of VRRP (Virtual Router Redundancy Protocol), which allows multiple virtual IP addresses to be assigned to ensure redundancy and high availability in a network. This setup allows one router to take over automatically if the primary router fails, maintaining network stability and functionality.

Question 5 of 36

After the session is re-established between the BGP GR helper and its neighbor, original forwarding entries are deleted.

    Correct Answer: B

    In BGP Graceful Restart (GR) mechanism, when a session is re-established between the BGP GR helper and its neighbor, the original forwarding entries are not deleted immediately. Instead, these entries are retained to ensure continuity of data flow and to prevent traffic loss during the restart process. The GR helper maintains these entries until it can update them based on new routing information received after the session is re-established.
