In a company network, a host sends an Ethernet frame destined to the address FF:FF:FF:FF:FF:FF.
What will an Ethernet switch do with this frame?
A network operator wants to make sure voice data is prioritized.
In this scenario, to which Ethernet traffic class should it be assigned.
A network operator who wants to make sure voice data is prioritized should assign it to Ethernet traffic class 6. Ethernet traffic class is a term used to refer to the priority code point (PCP) field in the VLAN header of an Ethernet frame. The PCP field is a 3-bit field that can encode up to eight different priority levels, ranging from 0 (lowest) to 7 (highest). The PCP values can be mapped to different types of traffic according to their QoS requirements. The recommended mapping is as follows :
PCP 0: Best effort (default)
PCP 1: Background
PCP 2: Spare
PCP 3: Excellent effort
PCP 4: Controlled load
PCP 5: Video
PCP 6: Voice
PCP 7: Network control
Voice data is a type of real-time traffic that requires the highest priority and lowest delay in the network. Therefore, it should be assigned to PCP 6, which corresponds to Ethernet traffic class 6 .
In OSPFv2, which route characteristic is used to determine the best path?
In OSPFv2, the route characteristic that is used to determine the best path is the cost. The cost is a metric that represents the link bandwidth, delay, reliability, or other factors. The cost is inversely proportional to the bandwidth, meaning that a higher bandwidth link has a lower cost. The cost of a route is calculated by adding the costs of all links along the path. OSPFv2 uses the following formula to calculate the cost of an interface:
Cost = Reference bandwidth / Interface bandwidth in bps
IPv6 link-local addresses are designed to be used in which three situations? (Choose three.)
In your network, video traffic is being marked with DSCP code AF31.
Based on industry standard practice, which code would you use to assign higher priority to VoIP traffic?
