Replace Item EnglishOption 4 can be considered a correct answer.





Change stem to include all the networks that

the the answer actually covers. What address

can be used to summarize networks

172.16.0.0/24 thru 172.16.7.0/24?"

The actual question "Which three commands can be used tohelp troubleshoot Layer 3 connectivity issues?" can beanswered correctly using every one of the options. Replaceitem with minor change to options.

Drop Item - DUAL is not discussed until chapter

4 and then in more detail in chapter 9.

The question should be worded correctly for a betterunderstanding.

It is difficult to determine whether the questionis looking for the flush or invalid timer. There isnot a valid answer for the flush timer, so the

only option would be using the invalid timer.

Content not covered in enough detail in the

curriculum

The course material does not refer to the term

LSA, but instead uses LSP.

Change correct answer to "Directly connected

networks that are operational will be in the

routing table."

Change option B to "Directly connected networks that areoperational will be in the routing table."

The IP address of the Remote routers S0/0/1

interface should be 10.2.0.6.

Option 1 is incorrect. RIP v2

does not pick up supernetted

network addresses directly from

interfaces as shown in the

exhibit.The protocol field in the exhibitshould be displayed as a

hexadecimal number 0x800.

The correct response is correct

according to RFC1058, but is not

consistent with the curriculum

presentation and may not be the

case on all systems.

The 10.0.0.0/24 network is directlyconnected to the BOS router and wouldnot rely on OSPF hello packets to appear

in the BOS routing table.

The exhibit command output

refers to RouterA rather than

R1. There is also an implicit

assumption that R2 is configuredwith ver2 and no auto-summary

which is not shown in the item.

The wrong exhibit is displayed

for this item.

The exhibit incorrectly shows staticroutes as directly connected.

An IP address must be assignedto the interface, even if it is up

and up, in order to show as a

directly connected route in the

routing table.

Summarization would not occur as the route hasnot crossed a border between network

numbers. Also, routes shown in the debug

output are not shown on the network diagram.
