An incoming frame is received by a transparent bridge. If the destination address of the frame is not present in the database, the bridge will:

What happens to an incoming frame on a Layer 2 switch?

What mechanism enables cut-through switches to process a frame with
reduced latency?

The diagram shows a collapsed L3 switched building backbone consisting of two L3 switches: W and U. Each L3 switch has a routed interface on every subnet (VLAN) in the building. There are no VLAN trunks in the network. In other words the L3 switches are acting as native routers. There are exactly 4 client-side VLANs (subnets): a, b, c, d. There are exactly 2 server-side VLANs (subnets): x and y. There is one routed link (Subnet e) connecting the L3 switches in the core. How many equal-cost paths to Subnet d does L3 Switch W keep in its routing table?

What statement is correct concerning the shown configuration?

What statement is false about RIP v1?

L3 switches R1 and R2 are in the backbone of the network. They are connected by a routed EtherChannel bundle consisting of eight Gigabit Ethernet ports. The routed link is represented as subnet X.0 in the diagram. Since X.0 is routed, it is not a VLAN trunk. How can spanning tree loops be prevented in the backbone of this network?

IDSL and SDSL use what line coding scheme?

What is true concerning fastpath versus interleaved mode in DMT DSL service?

A DSL subscriber says that his DSL modem is trained at the subscribed rates, 1024 kbps downstream and 256 kbps upstream, but he has no access to the internet. The internet service was working until today. The modem remains trained – it is not dropping train or frequently retraining. Manually retraining the modem does not correct the problem. The customer can ping from his PC to the Ethernet interface on the DSL modem, but not addresses “in the network”. Initial troubleshooting shows that the DSL modem can ping the subscriber’s PC, but no addresses in the network. What could cause this problem?
