• Question 52:

  What condition is NOT a valid criterion for initiating a BLSR protection switch?

  B. High path bit-error-rate (BER) indicated in the B3 byte
  C. Loss-oF. frame (LOF) alarm
  D. Request for a line switch in the K1 byte

• Question 53:

  How do FCIP and ISCSi differ?

  A. ISCSI is a mechanism for adding mid-level servers to a SAN, where FCIP is a means to connect SAN to SAN.
  B. ISCSI encapsulates a SCSI I/O request in a TCP/IP packet and routes it across an IP network. FCIP encapsulates native fibre channel into an IP packet and tunnels it across an IP network.
  C. ISCSi encapsulates native fibre channel into an IP packet and tunnels it across an IP network. FCIP encapsulates a SCSI I/O request in a TCP/IP packet and routes it across an IP network.
  D. ISCSi is a fibre channel replacement protocol and FCIP bridges the gap created when a customer migrates from pure fibre channel to ISCSi.
  A. ISCSI is a mechanism for adding mid-level servers to a SAN, where FCIP is a means to connect SAN to SAN.
  B. ISCSI encapsulates a SCSI I/O request in a TCP/IP packet and routes it across an IP network. FCIP encapsulates native fibre channel into an IP packet and tunnels it across an IP network.

• Question 54:

  How long is an ATM cell header?

  A. 5 octets (bytes)
  B. 3 octets (bytes)

  A. 5 octets (bytes)

• Question 55:

  When an ML-series RPR ring is provisioned over a SONET BLSR (or SDH MS-SPR) ring, the ML architecture can no longer utilize the full available bandwidth on the SONET/SDH ring due to the constraints of BLSR. Which features are being introduced to allow use of discontiguous timeslots and BLSR protect channels when provisioning ML-series RPR rings, in order to alleviate this limitation?

  A. Software Link Capacity Adjustment Scheme (SW-LCAS)
  B. Low Order Virtual Concatenation (LO-VCAT)
  C. Framed Generic Framing Procedure (GFP-F)
  D. High Order Virtual Concatenation (HO-VCAT)
  E. Bridge Control Protocol (BCP)
  A. Software Link Capacity Adjustment Scheme (SW-LCAS)
  D. High Order Virtual Concatenation (HO-VCAT)

• Question 56:

  What is the designation for regenerators that are bit rate dependent?

  A. 1R
  B. 2R
  C. 3R
  D. 1R, 2R and 3R
  C. 3R

• Question 57:

  Click the Exhibit button to view the topology.

  

  Host D sends a frame to Host B at the same time that Host B sends a frame to Host D. Bridging is enabled on Router 1 and the two frames collide into each other. Select the best explanation of why Host B will or will not receive the original frame from Host D:

  A. Host B will receive the frame, since Hosts B and D are in the same VLAN.
  B. Host B will receive the frame, since Hosts B and D are in the same routing domain.
  C. Host B will not receive the frame, since Hosts B and D are in the same collision domain.
  D. Host B will not receive the frame, since Hosts B and D are in different broadcast domains.
  E. Host B will receive the frame, since Hosts B and D are in the same bridging domain.
  C. Host B will not receive the frame, since Hosts B and D are in the same collision domain.

• Question 58:

  OSPF is defined on a Frame Relay interface providing point-to-multipoint connections. The remote neighbors can reach this central site, but are complaining of routing failures between each of the remote sites. The central router has all the routes for each remote site. Based on this information, what can be diagnosed as the biggest potential problem?

  A. An over-subscribed Frame Relay switch will cause some packet loss.
  B. There are problems in the use of OSPF Authentication.
  C. There is an incorrect selection of the Designated Router.
  D. There is an incorrect DLCI assigned on a point-to-point sub-interface.
  C. There is an incorrect selection of the Designated Router.

• Question 59:

  The ML-series Ethernet card provides up to how many active 802.1 Q in Q instances per card?

  A. 512
  B. 4095
  C. 255
  D. 1024
  C. 255

• Question 60:

  What is the equivalent of 50 GHz spacing in DWDM in terms of nm?

  A. 1.6 nm
  B. 0.8 nm
  C. 0.4 nm
  D. 0.2 nm
  C. 0.4 nm
