1.

For an OC-48 signal (2.5Gb/s), what is the BER (bit error rate) if there is 1 bit error every four days?

2.

What is the difference between Link LDP and targeted LDP?

Link LDP uses port 646 and targeted LDP uses port 711. LDP Hellos use unicast UDP for targeted and multicast UDP for link. Link LDP uses UDP for discovery and targeted LDP uses TCP for discovery. Link LDP uses port 711 and targeted LDP uses port 646. None of the above are true.

3.

What does the Switchport block feature do?

Blocks unknown multicast forwarding to the port Blocks unknown spanning tree to the port Blocking unknown VLANS to the port Blocks unknown unicast forwarding to the port

4.

Which best describes the advantages of L2VPN vs. L3VPN?

Layer 2 VPNs appeal to subscribers who run their own Layer 3 networks over the wide area and require Layer 2 connectivity from service providers. In this case, the subscriber manages their own routing information. Layer 2 VPNs and Layer 3 VPNs are the same service and there is no difference between them. Layer 3 VPNs (or the traditional RFC2547) appeal to subscribers who prefer to outsource their routing toservice providers. The service provider manages routing for the customer's sites. Layer 2 VPNs allow service providers to route IPX and DecNet for customers over their core. Layer 3 VPNs allow service providers to route and bridge IPX and DecNet for customers over their core.

5.

Assume there are two attachment circuits (AC-1, AC-2) and two pseudowires (PW-1, PW-2) connected to a multipoint VFI on PE-1. When receiving an Ethernet frame from AC-1 and the destination MAC address is
unknown to PE-1, to what circuit will the Ethernet frame NOT be forwarded?

AC-1 AC-2 PW-1 PW-2

6.

Which are the components of a TCI?

TPID CFI L/T Priority VID

7.

What is the difference between Link LDP and targeted LDP?

Link LDP uses port 646 and targeted LDP uses port 711. LDP Hellos use unicast UDP for targeted and multicast UDP for link. Link LDP uses UDP for discovery and targeted LDP uses TCP for discovery. Link LDP uses port 711 and targeted LDP uses port 646. None of the above are true.

8.

What specification defines LACP?

IEEE 802.11 IEEE 802.1q and IEEE 802.1p IEEE 802.3ad ITU Q.922 RFC2547

9.

What is the command switched-fr-dlci used for?

To create a local switching FR DLCI endpoint To allow PW Interworking with Frame Relay To provide DLCI-to-subinterface mapping to apply a service-policy To configure a Frame Relay pseudowire using L2TPv3 There is no such command

10.

MPLS traffic engineering routing information is carried by:

BGP MEDs MP-BGP OSPF Opaque LSAs or IS-IS TLVs RTP or RTCP packets
