Video Explanation

 

1. Your Frame Relay provider is guaranteeing you a certain amount of bandwidth that will be available to you at any given time. What acronym is used to describe that guaranteed bandwidth?

A. DE

B. CIR

C. LMI

D. BECN

E. FECN

 

2. A Frame Relay cloud consists of what device types?

A. Frame Relay switches acting as DCEs

B. Frame Relay switches acting as DTEs

C. Frame Relay routers acting as DCEs

D. Frame Relay routers acting as DTEs

 

3. Which of the following terms describes Frame Relay?

A. packet-switching

B. circuit-switching

C. relatively inexpensive when compared to other WAN connectivity methods

D. relatively expensive when compared to other WAN connectivity methods

 

4. What message types serve as keepalives between the DTE and DCE?

A. LMI

B. DLCI

C. DE

D. CIR

 

5. Short answer: What is the default encapsulation type of a Cisco router Serial interface?

 HDLC

6. Short answer: When LMI Autosense is in effect, what message type(s) does the DTE send to the DCE?

When LMI Autosense is in operation, the DTE will send three LMI Status messages -- Type q933a, Type ANSI and Type CISCO. The DCE will respond with one LMI Status message. The DTE sees that Status message coming in, and from that point on only sends the LMI Status message type that matches the type it received from the DCE. 

7. Short answer: When LMI Autosense is in effect, what message type(s) does the DCE then send to the DTE after receiving the message(s) referred to in question 6?

When LMI Autosense is in operation, the DTE will send three LMI Status messages -- Type q933a, Type ANSI and Type CISCO. The DCE will respond with one LMI Status message. The DTE sees that Status message coming in, and from that point on only sends the LMI Status message type that matches the type it received from the DCE. 

 

8. What command resulted in the following output?

LMI Statistics for interface Serial0 (Frame Relay DTE) LMI TYPE = ANSI
  Invalid Unnumbered info 0             Invalid Prot Disc 0
  Invalid dummy Call Ref 0              Invalid Msg Type 0
  Invalid Status Message 0              Invalid Lock Shift 0
  Invalid Information ID 0              Invalid Report IE Len 0
  Invalid Report Request 0              Invalid Keep IE Len 0
  Num Status Enq. Sent 121          Num Status msgs Rcvd 94
  Num Update Status Rcvd 0              Num Status Timeouts 26

A. show frame pvc

B. show frame lmi

C. show frame timeouts

D. debug frame lmi

 

9. What command resulted in the following output?

R1#
3d04h: Serial0(out): StEnq, myseq 49, yourseen 94, DTE down
3d04h: datagramstart = 0xE329E4, datagramsize = 14
3d04h: FR encap = 0x00010308
3d04h: 00 75 95 01 01 00 03 02 31 5E

A. show frame pvc

B. show frame lmi

C. show frame dte

D. debug frame lmi

 

10. Short answer: What protocol enables dynamic Frame Relay mapping?

Inverse ARP enables dynamic Frame Relay mapping. Inverse ARP is often disabled in today's networks, and this is done by running command "no frame-relay inverse-arp" at the interface level.
