Body Relay is a serious matter in your CCNA and CCENT cloud certifications exams, and for good motive. Body Relay is part of nearly each Large Space Community (WAN) you will ever work with, and you have to know easy methods to configure and troubleshoot FR to achieve success within the examination room and your job.
That can assist you go the CCNA and CCENT exams and be ready for real-world success, listed below are 10 free Cisco certification examination coaching questions on Body Relay. Some have selections, some don’t – in any case, there is not any a number of alternative on the command line!
1. Your Body Relay supplier is guaranteeing you a specific amount of bandwidth that shall be out there to you at any given time. What acronym is used to explain that assured bandwidth?
A. DE
B. CIR
C. LMI
D. BECN
E. FECN
2. A Body Relay cloud consists of what system varieties?
A. Body Relay switches performing as DCEs
B. Body Relay switches performing as DTEs
C. Body Relay routers performing as DCEs
D. Body Relay routers performing as DTEs
3. Which of the next phrases describes Body Relay?
A. packet-switching
B. circuit-switching
C. comparatively cheap when in comparison with different WAN connectivity strategies
D. comparatively costly when in comparison with different WAN connectivity strategies
4. What message varieties function keepalives between the DTE and DCE?
A. LMI
B. DLCI
C. DE
D. CIR
5. Quick reply: What’s the default encapsulation kind of a Cisco router Serial interface?
6. Quick reply: When LMI Autosense is in impact, what message kind(s) does the DTE ship to the DCE?
7. Quick reply: When LMI Autosense is in impact, what message kind(s) does the DCE then ship to the DTE after receiving the message(s) referred to in query 6?
8. What command resulted within the following output?
LMI Statistics for interface Serial0 (Body Relay DTE) LMI TYPE = ANSI
Invalid Unnumbered information 0 Invalid Prot Disc 0
Invalid dummy Name Ref 0 Invalid Msg Kind 0
Invalid Standing Message 0 Invalid Lock Shift 0
Invalid Info ID 0 Invalid Report IE Len 0
Invalid Report Request 0 Invalid Hold IE Len 0
Num Standing Enq. Despatched 121 Num Standing msgs Rcvd 94
Num Replace Standing Rcvd 0 Num Standing Timeouts 26
A. present body pvc
B. present body lmi
C. present body timeouts
D. debug body lmi
9. What command resulted within 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. present body pvc
B. present body lmi
C. present body dte
D. debug body lmi
10. Quick reply: What protocol allows dynamic Body Relay mapping?
Listed below are the solutions! No peeking!
1. (B). That is the Dedicated Info Fee – the CIR.
2. (A). A Body Relay cloud consists of Body Relay switches, and people are DCEs.
3. (A, C). Body Relay is a packet-switching protocol, and one main benefit of Body is its value – it is comparatively low-cost!
4. (A). The Native Administration Interface appears like some type of GUI, but it surely’s not. Amongst different capabilities, the LMI serves as a keepalive between the DTE and DCE. If there’s an LMI mismatch, the bodily interface will stay up however the line protocol will go down.
5. The default encapsulation kind of a Cisco Serial interface is HDLC, as verified right here with present interface serial0. This specific interface is shut down, however the default encapsulation kind nonetheless seems within the command output.
R1#present int serial0
Serial0 is administratively down, line protocol is down
{Hardware} is HD64570
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, loopback not set
6 & 7. When LMI Autosense is in operation, the DTE will ship three LMI Standing messages. The DCE will reply with one LMI Standing message. The DTE sees that Standing message coming in, and from that time on solely sends the LMI Standing message kind that matches the sort it acquired from the DCE.
8. (B) That output is the results of working the present body lmi command. A superb place to begin for Body Relay troubleshooting.
9. (D) That output is the results of working debug body lmi. At all times watch out when working debugs in a manufacturing community – by no means run a debug until you are positive of the ensuing output, which might overwhelm the router.
10. Inverse ARP allows dynamic Body Relay mapping. Inverse ARP is usually disabled in right this moment’s networks, and that is achieved by working the no frame-relay inverse-arp command on the interface degree.
