Number 10 should be

*a query for network 192.168.0.0/28*

???

In the figure, R2 has lost connectivity to the LAN attached to its FastEthernet interface. R2 immediately sends an Update to R1 and R3 noting the downed route. R1 and R3 respond with an acknowledgement.

In the figure, R2 has lost connectivity to the LAN and it sends out queries to all EIGRP neighbors searching for any possible routes to the LAN. Because queries use reliable delivery, the receiving router must return an EIGRP acknowledgement. (To keep this example simple, acknowledgements were omitted in the graphic.)

EIGRP Packet Types 9.1.4

Wrong,
Check Q8 in answers of Chapter 10.

Below is a correction to number 10.

10. Refer to the exhibit. Network 192.168.0.0/28 goes down. What type of packet does Router2 immediately send to Router1 and Router3?

*** a query for network 192.168.0.0/28 (correct answer)
- an acknowledgment packet to 224.0.0.9
- an update packet that is sent to 255.255.255.255
- a packet that contains the new routing table for R2
- unicast update packets to 192.168.1.1 and 192.168.2.1

I agree with this and confirmed it….Good luck everyone!!!

Just took the exam & looking at the correct answers from Cisco shows that #10 was wrong. Here’s the correct answer:

#10
Refer to the exhibit. Network 192.168.0.0/28 goes down. What type of packet does Router2 immediately send to Router1 and Router3?

—-> a query for network 192.168.0.0/28
an acknowledgment packet to 224.0.0.9
an update packet that is sent to 255.255.255.255

Of the steps given, what is the final step in the link state routing process?

successors are placed into the routing table

SPF computes best path to each destination network

–> LSPs are flooded to all neighbors to converge the network

DUAL algorithm is run to find best path to destination networks

Refer to the exhibit. What does JAX do with link-state packets from ORL?

–> sends out its updated routing table to both ORL and BOS routers

sends out the individual link-state packets out the interface connected to BOS

queries BOS to see if it has a better route

only adds it to the local routing table and performs no other actions
