This drag and drop question asks about the order of a DNS query.  The answer currently show as 'right' has steps 2 and 3 backwards.  How could the DNS request something from the domain DNS server before it knows it's address?  It doesn't receive that until it's requested it from the root DNS server.  The correct answer is as follows:

Step 1 => An endpoint submits a request for the IP address of a domain name
Step 2 => The DNS submits a request to a root DNS server
Step 3 => The DNS submits a request to the domain DNS server
Step 4 => The DNS receives a reply from the domain DNS server
Step 5 => The DNS responds to the endpoint

There are actually other steps that are skipped depending on how detailed you want to get, but the correct order of the provided event is above.  And example of a skipped step is that a DNS server first checks it's cache for unexpired entries to possible provide an answer to the endpoint immediately.  

Here are two links that backup this answer.

Isn't "Remove the 10.100.1.0/24 static route" the right answer? could you please also check  thanks

shouldn't it be "Configure the aaa authentication login admin group admin local enable command instead." ?

it should be "in" because we are filtering into Area20

Hi,

are all questions and simulations up to date for this exam 350-401. need to make sure everything is up to dat ebefore taking an exam. also are the questions same from here?

The ACL should be applied to SW1 Interface G1/10

https : // www . examtopics . com/discussions/cisco/view/82688-exam-300-410-topic-1-question-250-discussion/

Just failed the exam. Only had about 3 of the questions from this site, no help at all

On question QID:AN791

I believe the answer is not listed and should be:

"Configure the switchport trunk add vlan 300 on interface Fa0/2 on SW1"

The test states that it is just "switchport trunk allowed vlan 300"  but if you entered that CLI it would remove the existing trunk allowed vlans and only use vlan 300 rather than adding the vlan 300 to the existing trunk which is what you need.

The "add vlan 300 to interface Fa0/2 on SW1 is not even an option for an answer.

Passed, questions are good. Labs are good too but still got some wrong even with the right stuff from here. I studied them with CML and still could not get all of them working yet must have scored good enough on them and the questions to pass.

Thanks H2P

I think there's an issue with the answer of this question. The answer is listed as OSPF and BGP, but I believe the answer is LDP and RSVP.

The two protocols used by P routers to transfer VPN traffic between PE routers in an MPLS network are:
LDP (Label Distribution Protocol)
RSVP (Resource Reservation Protocol)

Explanation:

LDP is a protocol used in MPLS networks to distribute labels between adjacent label switch routers (LSRs). It allows P routers to assign and exchange MPLS labels for forwarding labeled packets along the Label Switched Path (LSP).
RSVP is a signaling protocol used in MPLS Traffic Engineering (MPLS-TE) to establish and maintain LSPs with specific bandwidth and quality of service (QoS) requirements. RSVP is used to reserve network resources along the LSP path.
The other options mentioned:

BGP (Border Gateway Protocol) is used for exchanging routing information between autonomous systems (AS) but not for transferring VPN traffic within an MPLS network.
OSPF (Open Shortest Path First) is an interior gateway protocol (IGP) used for routing within an AS but not for transferring VPN traffic in an MPLS network.
MP-BGP (Multiprotocol BGP) is used by PE routers to exchange VPN routing information and MPLS labels between VPN instances, but it is not used by P routers for transferring VPN traffic.


Please someone let me know if my understanding is not correct. Thanks!
