IEEE 802.1w is a Rapid Spanning Tree Protocol (RSTP) that can be seen as an evolution of the 802.1 standard. What are the port roles described by 802.1w?

For the following ports, which port is on every bridge in a Spanning Tree Protocol IEEE 802.1w network except the root bridge?

For the following items,what is the mathematical relationship between the committed information rate (CIR), committed burst (Bc), and committed rate measurement interval (Tc)?

Area Border Router (ABR) is a router located on the border of one or more OSPF areas that connect those areas to the backbone network. An ABR will inject a default route into which two types of areas? (Choose two.)

Which two steps below should you perform on the hub router while configuring EIGRP routing over DMVPN (mGRE tunnel)? (Choose two.)

Two routers are connected by a serial link, and are configured to run EIGRP on all interfaces. You examine the EIGRP neighbor table on both routers (using the show ip eigrp neighbor command) and see that the router connected over the serial link is listed as a neighbor for a certain amount of time, but is periodically removed from the neighbor table. None of the routes from the neighbor ever seem to be learned, and the neighbor transmission statistics (SRTT, RTO, and Q Count) seem to indicate that no packets are being transmitted between the neighbors. Which would most likely cause this problem?

Policy-based routing allows network administrators to implement routing policies to allow or deny paths based on all of these factors except which one?

Phase I and Phase II DMVPN differ in terms of which of these characteristics?

Which one of the following potential issues is eliminated by using split horizon?

Which switch port error is an indication of duplex mismatches on 10/100/1000 IEEE 802.3u Gigabit Ethernet ports?
