Which task must you perform to enable a point-to-point Frame Relay connection?
A. Enable inverse ARP.
B. Configure the encapsulation type.
C. Configure static address mapping.
D. Disable inverse ARP

I believe answer is B, since the first thing to do is execute the command “encapsulation frame-relay”, then you will have option to statically configure the addressing or not.

what do you think?

@AJS July PDF was updated and now it is named ROUTE_Oct_2019
it is publish on the section ROUTE FAQs & Tips

@AN thnks I get it.. someone has the updated D&D??????

@Troutes yeah these were all the D&Ds i had in the 3xam

@AN
I can’t find it in the faqs and Tips section. Please help me to find ROUTE_Oct_2019 .
thanks

@AJS
Can you check if the new questions that appeared to you are in ROUTE_Oct_2019?

hello, Could someone please send me the most recent dump = rendog31 @ gmail . com, many thanks

Hi, Kindly please share the latest dumps jeffreydantes15 @ gmail . com many thanks in advance.

guys do you know what is the diffrence between TCPMSS and PMTUD

@frk

TCPMSS is the maximum segment size which is actually the maximum payload size, defined by the endpoints at the time of the 3-way handshake.

https://www.cisco.com/c/en/us/support/docs/ip/transmission-control-protocol-tcp/200932-Ethernet-MTU-and-TCP-MSS-Adjustment-Conc.html

PMTUD is a mechanism to identify the best MTU size value of the whole path between 2 endpoints in order to avoid fragmentation.

https://en.wikipedia.org/wiki/Path_MTU_Discovery

@rush thanks for your ans.

I doubt in this question.

Route October Dump Question 31a

Which feature can mitigate fragmentation issues within network segments that are between GRE endpoints?
A. PMTUD
B. ICMP DF bit
C. TCP Flow Control
D. TCP MSS

Answer: D (In fact A is correct too) => its digitaltut’s answer.

I searched it too many times but all dumps say diffrent answer. I cant understand the trick.

what i conclude your reply, if there is fragmentation issue between endpoints then i’ll choose TCP MSS and if there is fragmentation issue on the path I’ll go with Path MTUD.

Is it True?

@ guys who wants to get exam questions from us with email.

Just Read Pleasee!!

Nobody will send anything. there is a section named route faq and tips above the share your experience. Please read it. you will be able anything you want.

Just passed the route exam with 8xx.

Labs: IPv6 Virtual link, OSPF (different area, ID and IP, but still /30) and EIGRP EVAL
DD: One new for SNMP asking about (MIB,traps,inform,SNMP manager, SNMP agent), One for GRE (in section DD in digitaltut), Frame Relay component, uRPF.
Most of the questions are here but I had about 12-13 new questions which are not here.

One question I remembered is something like “What will happen if passive-interface will be configured under RIP?”

@frk

Yes, that’s how i also get it. The trick, in my opinion stands in the “FEATURE” word in the question.
MSS is not a feature, it’s a value !
ICMP DF bit is the “Don’t Fragment” value per cisco :

https://www.cisco.com/c/en/us/support/docs/ip/generic-routing-encapsulation-gre/25885-pmtud-ipfrag.html

“PMTUD is only supported by TCP and UDP. Other protocols do not support it. If PMTUD is enabled on a host, and it almost always is, all TCP and UDP packets from the host will have the DF bit set. ”

TCP flow control regards speed; A host not to send packets faster than the receiver can accept.

So, all point to PMTUD which is the actual FEATURE per the question which is using the DF bit as well. Thus, “A”

@Mmm thanks for sharing your experience. Did you study with July pdf or Octuber pdf?

@AN can you confirm if the ROUTE_Oct_2019 is valid and having a premium account is enough to pass the route exam. Thank you.

I studied from July and digitaltut mainly, but I heard for Oct file yesterday.

I was having one question about what we need to configure if we want NTP authentication. I choose ntp trusted-key command.

I have one question which was with this diagram https://vceguide.com/which-statements-about-the-query-messages-sent-from-router-hq-r2-for-a-route-to-reach-the-12-12-12-12-32-network-is-true/ . It was asking if BR1 is configured with stub what will be seen in HQ-R1 and there was 4 outputs of the routing table.

Consider this scenario. TCP traffic is blocked on port 547 between a DHCPv6 relay agent and a DHCPv6 server that is configured for prefix delegation. Which two outcomes will result when the relay agent is rebooted? (Choose two)

A. Routers will not obtain DHCPv6 prefixes.
B. DHCPv6 clients will be unreachable.
C. Hosts will not obtain DHCPv6 addresses.
D. The DHCPv6 relay agent will resume distributing addresses.
E. DHCPv6 address conflicts will occur on downstream clients.

Answer: A D

Can someone please confirm if the above is correct ?

@RUSH
I have the same doubt.
Answers seem to be A and C

anyone can elaborate why D is a correct answer?

@rush
I searched for it

https://www.cisco.com/c/en/us/support/docs/ip/generic-routing-encapsulation-gre/25885-pmtud-ipfrag.html

read it please, this documentation explain everything. (scenario 5)

I understand like this.

The trick is “GRE”. it allows mtu 1476 but end user 1500 so we must use pmtud for this question. If there is no tunnel(gre,gre+ipsec etc.) between them we will use tcp mss.

Scenario 5
This scenario illustrates GRE fragmentation. Remember that you fragment before encapsulation for GRE, then do PMTUD for the data packet, and the DF bit is not copied when the IPv4 packet is encapsulated by GRE. In this scenario, the DF bit is not set. The GRE tunnel interface IPv4 MTU is, by default, 24 bytes less than the physical interface IPv4 MTU, so the GRE interface IPv4 MTU is 1476 as shown in the image.

@mmm
answer is
Router HQ-R1 receives query messages from HQ-R2 for a route to 12.12.12.12/32 network.
But it just accept query not answer because also hq-r1 doesn’t know where the route is.
becasue br1 stub, it will query with inaccessible. and we know hq r2’s interface is shutdown.

@rush
@JA

Clients listen for DHCP messages on UDP port 546 while servers and relay agents listen for DHCP messages on UDP port 547.

So if we block 547 i think no body get prefixes. yes routers will solicit with 546 but cant’t get an prefix with 547. and if routers cant get prefix, clients cant get it too.

relay agent work in only between client and relay part. it cant work on between relay and server part. so it will not work.

i think answer is A and C. Im not sure 100%

@frk

The answer is D and E ,

The question says it’s blocking TCP port 547, however DHCP traffic is UDP, so nothing is blocked.

@frk The relay agent utilises UDP for communications to the Server. Blocking TCP has no impact on the ability of of the relay agent to communicate with the DHCPv6 server. So, after reboot the Relay Agent again returns to normal operation and distributes the prefix delegation requests. If the Relay Agent is down for a period of time greater than the lifetime of the service then the prefix delegated are returned to the pool and hence may be reused after the reboot leading towards downstream conflicts. To understand the behaviour here I built the scenario in GNS3. Happy to provide the lab if you want to validate.

@Mmm Chinese sites are confirming the 6-10 question change happened yesterday on R&S and switching. Your question and several others such as the @frk stub question changing. I think they have stated that the question bank is currently unstable if I read it properly.

hi

i got lost in what Dumps should i study :-(
Can anyone send me dumps for the route exem
I have examcollection premium vce 190q but its no same questions as in NUQ5 &NUQ6
so im not sure if i should study it

i will send back examcollection premium vce 190q to who will send me valid dumps
and shed some light on thet

alexboch321 @ Gmail.com

Thenks Guys

Test Route Tomorrow afternoon!
fingers crossed!

@frk

That’s a really good find !! So the trick indeed is the GRE tunnel in this case.
So, PMTUD is the answer to this question for sure.

I still wonder is 446 pages a reasonable number ?? It’s just endless ..

Hi Guys

do we need to put the below mentioned commands in (IPv6 OSPF Virtual Link lab)

R4(config)#int loopback 0
R4(config-if)#ipv6 ospf 1 area 54

R1(config)#int loopback 0
R1(config-if)#ipv6 ospf 1 area 0

@Mmm the question about RIP and passive interface I think was in the earlier June pdf from digital tut and the June chinese pdf. RIP continues to listen to incoming advertisements it just does not send any. OSPF, EIGRP stop listening as well.

@Anonymous

Consider this scenario. TCP traffic is blocked on port 547 between a DHCPv6 relay agent and a DHCPv6 server that is configured for prefix delegation. Which two outcomes will result when the relay agent is rebooted? (Choose two)

A. Routers will not obtain DHCPv6 prefixes.
B. DHCPv6 clients will be unreachable.
C. Hosts will not obtain DHCPv6 addresses.
D. The DHCPv6 relay agent will resume distributing addresses.
E. DHCPv6 address conflicts will occur on downstream clients.

Answer: D E

Relay Agent uses UDP and blocking TCP does nothing. A is obviously incorrect meaning that D is correct. If the relay agent is off line long enough the lease expires on the server and when the agent comes back up can reissue same prefixes to other clients resulting in E being correct. Use GNS create a lab and you can see it.

Which access list entry checks for an ACK within a packet header?

A. access-list 49 permit ip any any eq 21 tcp-ack
B. access-list 49 permit tcp any any eq 21 tcp-ack
C. access-list 149 permit tcp any any eq 21 established
D. access-list 49 permit tcp any any eq 21 established

Answer: C

Can someone please explain why answer is C not D?
When range of standard access-list are 1~99?

Thanks.

@Anonymous
D cannot be the answer because access-list 49 is standard ACL.

Passed 8**
thank you digitaltut,
studied MPQ, D&D, last updates 5,6 , Sims

Hi, does anybody please have the latest VCE files for the Route Exam?
Thanks

Hi everybody!.
I got the October PDF file from ROUTE FAQ & Tips section.
When I try to convert to VCE, and open it states: “The Exam file contains no questions”.

Please help!

Thanks,
Rasher

@Ziba can you please share what D&D, LAB Sims, and MPQ you remember on the exam?

Nevermind. I got it!

@maybe

Consider this scenario. TCP traffic is blocked on port 547 between a DHCPv6 relay agent and a DHCPv6 server that is configured for prefix delegation. Which two outcomes will result when the relay agent is rebooted? (Choose two)

A. Routers will not obtain DHCPv6 prefixes.
B. DHCPv6 clients will be unreachable.
C. Hosts will not obtain DHCPv6 addresses.
D. The DHCPv6 relay agent will resume distributing addresses.
E. DHCPv6 address conflicts will occur on downstream clients.

Answer: A D

thanks, youre right completely. But i have a quest.

we are sure that blocking tcp on dhcpv6 means nothing. everything will be same. i understand dhcp relay agent keep going its work but how “Routers will not obtain DHCPv6 prefixes.” is possible?

@frk

I agree with @maybe ‘s previous post about correct answers being D, E.
After a reboot the router will resume the address distribution (D) and IF the leases’ table is erased, then it’s gonna supply duplicates to clients thus, there is a chance of conflict (E) .

@Ziba
So you are saying there is no need to study all the other questions on the right side of the page and just study MPQ, D&D, last updates 5,6 , Sims right?

@rush
@maybe

yeah guys, youre right, there is no way to be correct a b and c.
I’ll go with D and E too.
Thanks for your replies.

@frk

Someone called Anonymous posted the Answer is A D simply from the pdf. Answer A is incorrect. The relay agent uses UDP and port 547 in both directions. A TCP port 547 has no impact at all on anything. Answer is D and E.

I would recommend that when concerned about the validity of an answer, and it can not be addressed simply by research, knock it up in a lab, use wireshark and test it out. See how it works and learn from the experience. The latest chinese pdf has also now changed to be D and E and not A.

Question

Consider this scenario. TCP traffic is blocked on port 547 between a DHCPv6 relay agent and a DHCPv6 server that is configured for prefix delegation. Which two outcomes will result when the relay agent is rebooted? (Choose two)

A. Routers will not obtain DHCPv6 prefixes.
B. DHCPv6 clients will be unreachable.
C. Hosts will not obtain DHCPv6 addresses.
D. The DHCPv6 relay agent will resume distributing addresses.
E. DHCPv6 address conflicts will occur on downstream clients.

Answer: D E

@frk seems that the site will not let me post. If you want the gns project so you can make you own decision let me know.

@frk also keep in mind the topology here it is DHCPv6 Server-Relay Agent-DHCPv6 PD Client-DHCPv6 Client. The PD Client gets the Prefix Delegation and then uses RA to downstream if your doing stateless. The question blocks a TCP port between the DHCPv6 Server and the Relay Agent so the PD Client still has a PD for the lifetime that it had and will continue to provide RA messages.

@Anonymous Inverse ARP is enabled by default, encapsulation is default, need a DLCI. Answer is C.

Reference

@anonymous
@maybe

Which task must you perform to enable a point-to-point Frame Relay connection?
A. Enable inverse ARP.
B. Configure qathe encapsulation type.
C. Configure static address mapping.
D. Disable inverse ARP

B or C?

Point-to-point subinterface – With point-to-point subinterfaces, each pair of routers has its own subnet. If you put the PVC on a point-to-point subinterface, the router assumes that there is only one point-to-point PVC configured on the subinterface. Therefore, any IP packets with a destination IP address in the same subnet are forwarded on this VC. This is the simplest way to configure the mapping and is therefore the recommended method. Use the frame-relay interface-dlci command to assign a DLCI to a specified Frame Relay subinterface.

Multipoint networks – Multipoint networks have three or more routers in the same subnet. If you put the PVC in a point-to-multipoint subinterface or in the main interface (which is multipoint by default), you need to either configure a static mapping or enable inverse Address Resolution Protocol (ARP) for dynamic mapping.

I think answer is “configure encapsulation type” .

“frame-relay interface-dlci” command

is this command meaning static address mapping ? If it is, the answer will be C.

@frk that’s the way I interpreted it given the default values enable a point to point FR setup essentially.

Does anyone have recommendations on VCE software to use? I don’t mind paying a one time fee but all the sites I have seen look shady. I would like to convert the October PDF to to a VCE and test that.
