IP Routing 3
Question 1
Explanation
Floating static routes are static routes that have an administrative distance greater than the administrative distance (AD) of another static route or dynamic routes. By default a static route has an AD of 1 then floating static route must have the AD greater than 1. Floating static route has a manually configured administrative distance greater than that of the primary route and therefore would not be in the routing table until the primary route fails.
Question 2
Explanation
A host route for IPv4 has the mask /32, and a host route for IPv6 has the mask /128. If an IPv4 address is configured with a mask of /32 on an interface of the router, which is typical for loopback interfaces, the host route appears in the routing table only as connected (for example in the routing table we will see this line: “C 10.10.10.1/32 is directly connected, Loopback0”.

Question 3
Explanation
If the IP address exists in the routing table then we can say the local router knew the way to reach that destination. But this question wants to ask if the destination has communicated to the local router or not (“an IP address is known to a router”). Maybe it is a tricky question.
Question 4
Explanation
In all the way on the path, the source and destination IP addresses never change, only the source and destination MAC address are changed on each segment.
Question 5
Question 6
Question 7
Question 8
Question 9
Question 10
Question 11
Explanation
To check the connectivity between a host and a destination (through some networks) we can use both “tracert” and “ping” commands. But the difference between these 2 commands is the “tracert” command can display a list of near-side router interfaces in the path between the source and the destination. The “traceroute” command has the same function of the “tracert” command but it is used on Cisco routers only, not on a PC -> B is correct.
hi 9tut,
where can i find questions for these?

Q5) When is a routing table entry identified as directly connected?
A. When the local router is in use as the network default gateway
B. When the network resides on a remote router that is physically connected to the local router
C. When an interface on the router is configure with an ip address and enabled
D. When the route is statically assigned to reach a specific network
Why answer is not B) and in the .pdf is given C) as the right question ?
Can someone please explain Q6?
Besides the misspellings… is it simply that the static route is separate from the interface address and thus the interface address route? Is the question simply trying to confuse by mentioning “static route” and “directly connected route” together, and the answer that makes most sense is simply the static route is the ONLY route, so it is obviously the PREFERRED route? Seems like a hokey question… Or am I missing something else here?
Thanks!
Q6) Router R1 has a static router that is configured to a destination network. A directly connected inference is configured with an IP address in the same destination network. Which statement about R1 is true?
A. It refuses to advertise the dynamic route to other neighbors
B. It sends a withdrawal signal to the neighboring router
C. It disables the routing protocol
D. It prefers the static route
Answer is D?
Hi there,Can anyone send me the latest CCNA questions
email it to me plz ahmedalaridh@ gmail.com
Q6: I thought a “directly connected” route with an AD of 0 would be preferred over a “static” route with an AD of 1? But that’s not an avail answer. Why is the static preferred (answer d)?
About q6.
When you are configuring static route to directly connected network, then route to DC network will be “threated” by static route and in routing table you’ll see only static with 1/0 AD
Q6: I tried this in Packet Tracer, with a static route to the same directly connected network, the DC still shows in the routing table. I tried several different ways. I guess PT could be misleading, but I’m still not seeing it, and can’t find anything online to substantiate it. What is the technical reason that a DC route would show up as a static route? Especially when the AD of a DC route (0) is preferred over a static route (1) ?
Q6:
Maybe that’s the only answer that would rather made sense. The other 3 options have nothing to do with preferring of DC vs. Static routes. If there is an option of DC is preferred, then choose it.
I got confused between Q6 and Q7.. Can someone explain ?
@Mustafa,
there is a mistake. Q7 should be B.
Q3: When troubleshooting ethernet connectivity issues, how can you verify that an IP address is known to a router?
A) check whether the IP address is in the routing table
B) check whether an ACL is blocking the IP address
C) check whether the IP address is in the CAM table
D) check whether the IP address is in the ARP table
I believe 9tut says (D). But the ARP table is rarely complete with all IP addresses. Without a recent inquiry of an IP, it will NOT be in the ARP cache. If the question mentioned PING and ARP, I would be swayed, but to simply look at the ARP table (cache) it would not tell anything about an IP address that is configured but “idle”. It would not show up!
However, if it’s in the routing table, the router KNOWS how to get to it, and thus KNOWS about the IP. Look at the routing table for an address, if it knows about the address it will show you what interface it’s on, or how to get to it. Either way, it KNOWS about it. If it’s not in the routing table, it doesn’t KNOW anything about it.
But with the wording of the question (IP address), I can see the logic of looking to ARP. But the wording of the answers “check whether it’s in…” doesn’t say to first PING, it just says to LOOK. HMMM… any comments? As usual, if we understand the logic, I think the actual exam question should be more clear.
@cthelite
After reading your explanation I agree with you. For sure the question is unclear but after following what you wrote, it would be A).
about Q6 its very simple when we are looking at Q7 the same question …
so waspenterprise is right :
( Maybe that’s the only answer that would rather made sense. The other 3 options have nothing to do with preferring of DC vs. Static routes. If there is an option of DC is preferred, then choose it.)
cos Q7 the option of DC is present and its the right answer
so don’t be confused Mustafa
@9tut
Question 4
If Computer A is sending traffic to computer B, which option is the source IP address when a packet leaves R1 on interface F0/1?
A. IP address of the R2 interface F0/1
B. IP address of computer B
C. IP address of R1 interface F0/1
D. IP address of Computer A
You mentioned answer as D. But it can be B as well. B & D. Pls confirm?
@9tut
Please ignore my above comment. Just realised that the question says “which option is the SOURCE IP”. You have answered it correctly as host A is the source computer.
In all the way on the path, the source and destination IP addresses never change, only the source and destination MAC address are changed on each segment.
Question 8
In which situation would the use of a static route be appropriate?
A. To configure a route to the first Layer 3 device on the network segment.
B. To configure a route from an ISP router into a corporate network.
C. To configure a route when the administrative distance of the current routing protocol is too low.
D. To reach a network is more than 15 hops away.
E. To provide access to the Internet for enterprise hosts
Correct answer is B I believe. E would be the correct answer for a “default” route, not a static route. The corporate router is configured with the “default” route towards the ISP router, and the IPS Router is configured with a static route towards the corporate network.
Any comments?
Q8 – thinking about it, E is the goal of configuring the static route on the ISP, (to provide access to the Internet). so two correct answers ?
Q6 seems wrong. Q5 seems ridiculous.
IP Routing 2 was full of confusing questions as well (weather a default route is installed or not)
Can anyone confirm that these are the real questions?
Considering the typos I do not believe these are the actual questions…
hi guys , any one has rip question came in exam distance 50 ?
Q6 & Q7:
The same question, but different conclusions depending on the provided answers.
Q6: the best answer is the static route based on the answer options.
Q7: the best answer is the directly connected interface based on the answer options.
A directly connected interface will have an AD of 0, whereas a static route has an AD of 1.
Read the question, then read the answers.
9TUT check over spellings for Q6
Anyone have an opinion on question 3
Q3: When troubleshooting ethernet connectivity issues, how can you verify that an IP address is known to a router?
A) check whether the IP address is in the routing table
B) check whether an ACL is blocking the IP address
C) check whether the IP address is in the CAM table
D) check whether the IP address is in the ARP table
Im thinking A) Ip address in routing table.
for question 3 is the answer C or D im getting different results in the quiz and explanation
Hiii, can anyone send me the latest CCNA questions on ikrimah dot muiz95@gmail dot com
Foxterrier
I think the same, the correct answer should be the B. But the option E appears in the PDF file, Im not sure what belive. But we need pick option E as per the pdf for the moment.
Q6.
Maybe the question is:
Router R1 has a dynamic route to a destination network.
@ALL
Don’t get confused when you see Q6, it’s a wrong question. Slide down to Q7, that’s is the right one.
Question 8
In which situation would the use of a static route be appropriate?
A. To configure a route to the first Layer 3 device on the network segment.
B. To configure a route from an ISP router into a corporate network.
C. To configure a route when the administrative distance of the current routing protocol is too low.
D. To reach a network is more than 15 hops away.
E. To provide access to the Internet for enterprise hosts.
The answer is E but I think it’s more correct for “default route”. So my answer is B for this questions. What do you think?
which definition of a host route is true ?
A. A route that is manually configured
B. A route used when a destination route is missing.
C. A route to the exact /32 destination address
D. Dynamic route learned from the server
Hi,bashar
I think it’s C, because “A host route for IPv4 has the mask /32″…
