@ Rizwan
Answer A is definitely wrong. In my opinion answer D seems to be the right one.
Imagine that you are running any FHRP protocol on the distribution level and then the Core which is doing equal-load balancing towards both DSW (active/standby).
In this scenario the traffic flows out using one path only but returning using both. The problem here is that on the standby DSW there might be an ARP entry missing
in the cache (as the traffic initially leave the enterprise using active one, default gateway, which obviously have the ARP). This cause Standby DSW to flood this unknown
unicast traffic out all its other ports. This issue is known as asymetric routing.

@jbalvin
I believe the answer is A-PMTUD
I clearly described in the link you attached TCP MSS takes care of fragmentation at the two endpoints of a TCP connection, but it does not handle the case where there is
a smaller MTU link in the middle between these two endpoints (meaning that fragmentation on various routers along the way would still occur in case if the MTU size
would be less than on the endpoints). PMTUD was developed in order to avoid fragmentation in the path between the endpoints. It is used to dynamically determine
the lowest MTU along the path from a packet’s source to its destination.

Also i am wondering whether the answer to below question is correct.
any ideas here?

Which cisco Express Forwarding component(s) contain forwarding information?

A. FIB, adjacency table
B. adjacency table.
C. FIB, RIB, Adjacency table
D. FIB
E. RIB

In my opinion D is the correct one not A.
FIB contains forwarding information and adjacency table only provide layer 2 next-hop addresses for all FIB entries. Adjacency table is indeed CEF component but it is based on FIB where to forward as it It maintains a mirror image of the forwarding information contained in the IP routing table.

@Donaldo
Well done please back to your cave

@ next_try
Qoute “Thanks a lot for sharing your warm words with us but I think we all here knows the situation we have ! Please be so kind and if you remember you about more details…please share this information with us instead !
By the way…what was your result in the Exam and how did you prepaire ?
Thanks a lot in advance.”

As you may well know that we are not allowed to reveal our scores however I fell short by a few questions, possibly only two Q and A out, so really just unlucky.

I prepared via various uptodate dumps the 480 dump in February, this site and in the premium section… I do have to srress though I did kind of rush the study process and didn’t take my time and thought my experience and level of competence would play a factor in passing, so I was under prepared as I had only had about 80 percent ready, and even then I was struggling to remember.

I would be retaking it in a few Months, hopefully sooner but be taking my time to learn the concepts, and go over the material more methodically before I spent a large amount of money for the exam.

The route exam is by far the hardest of the three with topics ranging from IPv6, IPSLA, SNMP Authentication, VRF lite concepts, BGP Multihop and the effects of disabling split horizon, VPNs, DMVPN… etc… the exam is rightly the more difficult because this is the main topic for the CCNP.

Good luck everyone and I would advise you to not book the exam if you are not at least 90 percent prepared, do all the Q & As that are on here especially the new updated questions in the premium section as there were definitely questions from there about 25 odd at least, the rest of the questions as I said in my original post is sporadic.

Focus on IPv6, VPNs, IPSLA’s, Frame relay protocols, VRF-lite, NAT, OSPF, EIGRP, too be honest you best study the lot!!!

Drag and Drops They are all correct” “All of them”,
Simulations are all correct and up to date, just pay attention to the ip addresses, OSPF process ID’s and EIGRP AS numbers on the exam, “I had no problem with these and done each one in about 5 minutes.

EIGRP Stub – The 255.255.240.0 subnet mask on R4 serial0/0 did not work in the exam to create two 10.0.0.0 subnets on R3, you need to use the 255.255.0.0 subnet for it to work.

I will be studying over again… and retaking hopefully by next month or the month after.

@Johny Bravo

Yes I would agree with you about the PMTUD/TCP MSS question:

Taken from a cisco website,

“TCP MSS as described earlier takes care of fragmentation at the two endpoints of a TCP connection, but it does not handle the case where there is a smaller MTU link in the middle between these two endpoints. PMTUD was developed in order to avoid fragmentation in the path between the endpoints.”

Forgot to add the following new D&D that came up in the exam
The Drag and Drops that need to be added are:-

————————-
LMI
**Address registration – allows neighboring Cisco devices to exchange the management ip addresses

**Global addressing – Enables Frame Relay to identify interfaces in same manner as LAN

**Multicasting – Provides most efficient transmission of routing protocol messages and support address resolution

**Simple flow control – Supports devices that are unable to use congestion notification

**Virtual circuit – Prevents data from being transmitted in black hole

————————-
IP DHCP-Relay
**option: Insert relay information in BOOTREQUEST

**check: Validate relay information in BOOTREPLY (global configuration command) If an invalid message is received, the relay agent drops it

**policy: Define forwarding rules

**trusted-sources: Configures all interfaces on a router as trusted sources of the DHCP relay information option.

**Information: Configured in global configuration mode, applied to all interfaces

subscriber-id: Perform this task to enable an ISP to add a unique id,and assign specific actions (for example, assignment of host IP address,subnet mask, and domain name system DNS), and to trigger accounting.

————————-

PPPoE
+ PADI: Signal sent by host to remote devices
+ PADO: Signal sent by remote device back to host
+ PADR: Unicast signal sent by host to remote device
+ PADS: Unicast Signal sent by remote device back to host
+ PADT: Singal is sent to terminate

*Which two commands do you need to implement on the CALLING router to support the PPPoE client? (choose Two)
A. peer default ip address pool
B. mtu
C. bba-group pppoe
D. pppoe enable group
E. pppoe-client dialer-pool-number

Correct Answer: BE

How2pass.com has the answers as AD

Are we sure about the answer?

& Johnny

Definitely B & E or MTU and PPPoE-Client Dialer-Pool-Number, this came up in the actual exam.

does anyone take the exam in that days ?!

someone have a premium account in digitaltut? can comfirm the question ?

@XxpresService

Were those DnD’s worded exactly how you just posted them?

@Johny Bravo: for example HSRP (Cisco proprietary FHRP) does not load balancing by default, the issue you speak about could happen if there is a fault of active host.

about Fib question, I’m not agree with you: adjacency table contain forwarding information for sure. (In my opinion A could be the right choose). But users reported that A and D options not appeared in the exams.

About PMTUD question be careful during the exam if it is right written. Maybe you could find PMTU or other.

@Johny Bravo

I mentioned a previous explanation on this subject (based on the Cisco site).

All in all, it is assumed that you have a programming background to accommodate this easily.

You can refer to page 78 and 80 in this forum. We can even discuss this issue if the explanation

does not convince you.

@Johny Bravo

As yesterday, we saw that some of people who tested said that options A and D were not

mentioned in the exam, and this is a confirmation of my words before.

Dear All,

Based on your exam experience, please share the new questions

@ EIGRP Stub
I think you misunderstood my sentence. I did not mean FHRP is doing load-balancing but Core toward FHRP (active and standby). So for instance when the host generate traffic to default gateway which would be VIP (traffic will go to active only) then will be send to core and then to internet. On the way back it will load balance to both active and standby (this can occur in certain condition of course) but if standby receive it, it will need to resolve ARP for the host flooding unicast to all ports (unless cache, but since standby then unlikely)

In regards to CEF components we have only two: FIB and adjacency table and my opinion is that FIB is the one that is doing actual layer 3 work. I could not see anyone reporting the answer “D” missing for FIB but i agree that some people said “A” was not there.

@ISAKMP
Not sure to what part/question you were referring, sorry

@next_try

Could You share Your pdf with new questions PLEASE,

Thanks in advance. You are Good Man.

Hi Guys, yes we had this question some times ago but please can someone explain the difference here again or maybe to share a link with a good explanation ?!

Questions are

1. Two limitations use NPTv6 for IPV6 to IPV6 Address translation ?（choose two）
or
2. When use NPTv6 for IPv6 to IPv6 Address translation ?

Answers :
A. stateful address translation
B. a limit of 32 1-to-1 translations
C. lack of overloading functionality
D. identify all interface NAT inside or outside
E. one-to-one prefix rewrite
F. mismatched prefix allocations
Correct Answer: CE or CF

Also please this question…

The enterprise network WAN link has been received several denial of service attacksfrom both IPv4 and IPv6 sources. Which three elements can you use to identify an IPv6 packet via its header, in order to filter future attacks?(Choose three)

A. Traffic Class
B. Source address
C. Flow Label
D. Hop Limit
E. Destination Address
F. Fragment Offset
Correct Answer: ACD or BCE ?

Gave today and failed by a very little marging.

The story about lot many new questions in MCQs is true. Lab and Sims are still same. PBR lab, EiGRP eval sim and EIGRP Stub sim is what I had. Questions about yellow and purple vrf something which people are talking earlier. 1 question was about OSPF T1 to Frame relay. D&D were mostly from the dumps. I will add more questions as I remember.

Focus on concept if you are using dumps, you should still be able to clear it. But better wait for the situation to be a little clear.

@mister x

D. Hop Limit
E. Destination Address
F. Fragment Offset
Correct Answer: ACD or BCE ?

The answer is BCE and I can’t recall the exact cisco.com article, but it says very exactly that DoS in IPv6 uses the source, destination, and flow label for this.

Which cisco Express Forwarding component(s) contain forwarding information?

A. FIB, adjacency table
B. adjacency table.
C. FIB, RIB, Adjacency table
D. FIB
E. RIB

I asked a network engineer at my work about this question, and he said that D is the correct answer. I agree with Johnny Bravo. In my opinion, FIB is L3 and adjacency table is L2. Forwarding is a L3 action, switching is L2. Do you all agree with me??? I personally hate this question because of the ambiguity of the phrase “forwarding information”.

Because at the same time, FIB is like a table of ip addresses, subnets, next hops, and exiting interfaces — without routing protocols, metrics, feasibility successors, load balancing, etc. An adjacency table has the direct neighbor that that interface is connected to. What is meant by forwarding? Because the packets are being forwarded technically in both tables.

What about this question…is it DnD or a Question with 3 Answers ?

About vrf red and vrf blue questions, The Enginneer make a sh ip route… What is the result:
Router(config)#ip route vrf blue 0.0.0.0 0.0.0.0 192.168.1.1
Router(config)#ip route vrf red 0.0.0.0 0.0.0.0 192.168.1.2
If you type “show ip route” you will see “Gateway of last resort it not set”.
If you type show ip route vrf blue” you will see “192.168.1.1 as gateway of last resort”.
Global routing table does not overlap with VRF routing tables.

For the second one:
2. When use NPTv6 for IPv6 to IPv6 Address translation ?

Answers :
A. stateful address translation
B. a limit of 32 1-to-1 translations
C. lack of overloading functionality
D. identify all interface NAT inside or outside
E. one-to-one prefix rewrite
F. mismatched prefix allocations

Correct Answer: CE seems to be the right one

NPTv6 cannot do any sort of NAT address overloading. Instead it simply translates one IPv6 prefix to another.

@Anonymous

are you mean a lot of question not here on comments and on others dumps
my exam 14/3 i can’t schedule

Cisco Express Forwarding stores “forwarding information” (outbound interface and MAC header rewrite) for adjacent nodes in a data structure called the “adjacency table”. Do your proper choose.
https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipswitch_cef/configuration/15-mt/isw-cef-15-mt-book/isw-cef-overview.html

@Anonymous,

Did you study, Dexter’s dump? It seem to cover all the content for the exam, especially vrf.

almost i cover 4 different vendors dumps but still there were some questions which were not seen before in dumps

i have Dexter and Chinese what you have else?

Hi Team,
can someone please let me know the correct answer please ?
For me its still ICMP but

The Neighbor Discovery Protocol in ipv6 is replaced with which discovery protocol in ipv4?
A. ARP
B. ICMP
C. UDP
D. TCP
E. RFC
Correct Answer: A but it could be also B ?

Cisco Express Forwarding stores forwarding information (outbound interface and MAC header rewrite) for adjacent nodes in a data structure called the adjacency table.

Cisco Express Forwarding uses a forwarding information base (FIB) to make IP destination prefix-based switching decisions.

The FIB contains the prefixes from the IP routing table structured in a way that is optimized for forwarding.

This is from the cisco.com website, so I guess therefore Adjacency and FIB are correct? Do you all agree?

Test

@Johny

QUoting same statements in CCIE Official GUide Routing Switching v5.0

“FIB stores only destination
prefixes alone. The forwarding information itself is stored as Layer 2 rewrite information
in the adjacency table, and entries in the FIB point toward appropriate entries in the adjacency
table. All FIB entries that describe networks reachable through a particular next
hop point to the same adjacency table ent”

You may also please refer the FIB and adjacency table in the Internet as below flow
— FIB contains ajdacency pointer that points to adjacecny table which contains the forwarding information. It is called TRIE, where you dont have the data, but you know who has the data( in this case by using adjacency pointer of cource) ISAKMP please correct me if I am wrong on this lol

@ISAKMP never bored to keep repeating himself in the subject(Thanks for your effort man)

ME myself personally will agree with ISAKMP opinion

@Confuse Guy

I appreciate your response. So we will go only with adjacency table correct?

Question 6

logging console 7. Which is true ?

A. You can see debug if you are connected in SSH
B. High CPU utilization
C. Log will show on active console connection only

digitaltut.com says the answer is B, but C is more correct right?

Question 26

Which statement about stateless and stateful IPv6 autoconfiguration are true?

A. Both stateless and stateful autoconfiguration require additional setup
B. Stateless autoconfiguration requires no additional setup, whereas stateful autoconfiguration requires additional setup
C. Stateless autoconfiguration requires additional setup, whereas stateful autoconfiguration requires no additional setup
D. Both stateless and stateful autoconfiguration require no additional setup

Answer: A

This is correct right, because you still have to configure stateful or stateless? Please offer your input.

I’m going to take my exam next week,
Can someone send the new DnD questions?

Hi guys, I have just passed the CCNA exam. Really want to continue towards CCNP routing. Could anyone suggest how should I approach the exam. What should be a better choice for videos ? CBT nuggets or UDEMY? Besides, i want to continue work on the dumps and the labs from the very begining. Please guys share your valuable experience. Thanks in advance.

Question 24

Drag drop about AAA commands.

Answer:

if-needed Does not authenticate if the user has already been authenticated on a tty line.
krb5 Uses Kerberos 5 for authentication (can be used only for Password Authentication Protocol [PAP] authentication)
local Uses the local username database for authentication.
none Uses no authentication.
group radius Uses the list of all RADIUS servers for authentication.
group tacacs+ Uses the list of all TACACS+ servers for authentication.
group group-name Uses a subset of RADIUS or TACACS+ servers for authentication as defined by the aaa group server radius or a

Is this accurate for the AAA DnD everyone is talking about? I skimmed the article associated with this concept and could not find anything other than these terms listed. Can someone who took the exam offer their input please?

@ next_try

I tested below in the lab, and all 3 answers are correct. Second command will not override BLUE vrf table, however, the command itself will be present in the run-config.

About vrf red and vrf blue questions, The Enginneer make a sh ip route… What is the result:
Router(config)#ip route vrf blue 0.0.0.0 0.0.0.0 192.168.1.1
Router(config)#ip route vrf red 0.0.0.0 0.0.0.0 192.168.1.2

If you type “show ip route” you will see “Gateway of last resort it not set”.
If you type show ip route vrf blue” you will see “192.168.1.1 as gateway of last resort”.
Global routing table does not overlap with VRF routing tables.

Regarding second one, it is ARP for sure.

The Neighbor Discovery Protocol in ipv6 is replaced with which discovery protocol in ipv4?
A. ARP
B. ICMP
C. UDP
D. TCP
E. RFC
