NEW QUESTION # 47
Refer to the exhibit.
R2 is a route reflector, and R1 and R3 are route reflector clients. The route reflector learns the route to
172.16.25.0/24 from R1, but it does not advertise to R3. What is the reason the route is not advertised?
- A. In route reflector setups, prefixes are not advertised from one client to another.
- B. Route reflector setup requires full IBGP mesh between the routers.
- C. In route reflector setup, only classful prefixes are advertised to other clients.
- D. R2 does not have a route to the next hop, so R2 does not advertise the prefix to other clients.
Answer: D

Answer: D
Explanation:
We need to use Policy Based Routing (PBR) here on Bangkok router to match the traffic from 192.168.3.0/24 & 192.168.4.0/24 and "set ip next-hop" to HongKong router(172.18.1.2 in this case).
Note: Please notice that we have to apply the PBR on incoming interface e0/3 to receive traffic from 192.168.3.0/24 and 192.168.4.0/24.

tunnel mode gre multipoint
ip nhrp redirect
Answer: B
Explanation:
The hub must be configured with ip nhrp redirect to notify the spokes of optimal routing paths.
tunnel mode gre multipoint is required for DMVPN. The spokes must be configured with ip nhrp shortcut to support direct spoke-to-spoke communication. tunnel mode gre multipoint is also necessary. This setup ensures optimal routing with direct spoke-to-spoke communication.
NEW QUESTION # 63
Refer to the exhibit.
An engineer is trying to generate a summary route in OSPF for network 10.0.0.0/8, but the summary route does not show up in the routing table. Why is the summary route missing?
- A. The summary route is visible only in the OSPF database, not in the routing table.
- B. There is no route for a subnet inside 10.0.0.0/8, so the summary route is not generated.
- C. The summary-address command is used only for summarizing prefixes between areas.
- D. The summary route is not visible on this router, but it is visible on other OSPF routers in the same area.
Answer: B
Explanation:
Explanation
The summary-address is only used to create aggregate addresses for OSPF at an autonomous system boundary.
It means this command should only be used on the ASBR when you are trying to summarize externally redistributed routes from another protocol domain or you have a NSSA area. But a requirement to create a summarized route is:
The ASBR compares the summary route's range of addresses with all routes redistributed into OSPF on that ASBR to find any subordinate subnets (subnets that sit inside the summary route range). If at least one subordinate subnet exists, the ASBR advertises the summary route.
NEW QUESTION # 64
Refer to the exhibit.
An engineer has configured policy-based routing and applied the configured to the correct interface. How is the configuration applied to the traffic that matches the access list?
- A. It is forwarded using the routing table lookup.
- B. It is sent to 209.165.202.129.
- C. It is sent to 209.165.202.131.
- D. It is dropped.
Answer: C
Explanation:
The set ip next-hop verify-availability command in route-map configuration mode to configure policy routing to verify the reachability of the next hop of a route map before the router performspolicy routing to that next hop. In this question we see track 100 is down so the PBR will not use this next-hop, it will use the second next-hop with track 200 (up).
NEW QUESTION # 65
Refer to the exhibit. Which action resolves the authentication problem?
- A. Configure the user name on the TACACS+ server
- B. Configure the same password between the TACACS+ server and router.
- C. Configure the TCP port 49 to be reachable by the router
- D. Configure the UDP port 1812 to be allowed on the TACACS+ server
Answer: B
Explanation:
From the last line of the output, we notice that the result was "Invalid AUTHEN packet". Therefore something went wrong with the username or password.

NEW QUESTION # 68
Which two solutions are used to overcome a flapping link that causes a frequent label binding exchange between MPLS routers? (Choose two)
- A. Increase a hold-timer to protect the session.
- B. Increase a session delay to protect the session.
- C. Increase input queue on links to protect the session.
- D. Create targeted hellos to protect the session.
- E. Create link dampening on links to protect the session.
- F. When a link flaps (for a short time),
Answer: D,E
Explanation:
...
Solution:
+ When LDP session supported by link hello is setup, create a targeted hello to protect the session.
Explanation:
To avoid having to rebuild the LDP session altogether, you can protect it. When the LDP session between two directly connected LSRs is protected, a targeted LDP session is built between the two LSRs. When the directly connected link does go down between the two LSRs, the targeted LDP session is kept up as long as an alternative path exists between the two LSRs.
For the protection to work, you need to enable it on both the LSRs. If this is not possible, you can enable it on one LSR, and the other LSR can accept the targeted LDP Hellos by configuring the command mpls ldp discovery targeted-hello accept.

NEW QUESTION # 69
An engineer notices that R1 does not hold enough log messages to identify the root cause during troubleshooting. Which command resolves this issue?
- A. (config)#logging buffered 4096 informational
- B. (config)#logging buffered 16000 informational
- C. #logging buffered 4096 critical
- D. #logging buffered 16000 critical
Answer: B
Explanation:
The router will theoretically accept a wide range of buffer sizes ranging from 4,096 bytes (nothing smaller) to an astronomical 2,147,483,647 bytes (about 2 GB). Exercise caution when choosing the size of your logging buffer because it comes out of the router's system memory. A good rule is to set your logging buffer to 16 KB for smaller routers. Routers with more than 32 MB of memory can safely dedicate 32 KB, or even 64 KB, without problems. To be safe, always check the amount of free memory on your router with the show memory command before increasing your buffer size.
Set the buffer size to 16,000 bytes, and the severity level to informational, by using a single configuration command.
