Review the exhibit.
A service provider wants to connect the sites for two customers (indicated in red and green in the exhibit). The two customers are using the same IP ranges 192.168.0.0/16.
Referring to the exhibit, what should the service provider do to accomplish this task?
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.)
