NEW QUESTION # 56
Refer to the exhibit.
Refer to the exhibit. An engineer is designing an OSPF network for a client. Requirements dictate that the routers in Area 1 should receive all routes belonging to the network, including EIGRP, except the ones originated in the RIP domain. Which action should the engineer take?
- A. Make area 1 a NSSA.
- B. Make the area 1 routers part of area 0.

NEW QUESTION # 57

Answer: D
NEW QUESTION # 58
An architect must create a QoS solution for a customer to ensure that a 40 Mbps Internet connection is shared between four subnets based on these requirements:
* Each subnet must receive no less than 10 Mbps of download bandwidth during peak traffic times.
* A subnet can use up to 40 Mbps during nonpeak traffic times if the other subnets are idle.
* Download traffic must never experience a delay.
Which solution must the architect choose?
- A. shaping and policing
- B. rate-limiting and shaping
- C. bandwidth percentage and rate-limiting
- D. bandwidth percentage and policing
Answer: D
Explanation:
Explanation
Selected answer: B
"Download traffic must never experience a delay."
This means we shouldn't be using Shaping at any point (since that puts packets into a buffer and sends them out later on when congestion has been reduced) Also: "Rate-limiting" is a bigger term and under it we have 2 things: "Policing" and "Shaping"

Explanation:
NEW QUESTION # 60
Refer to the exhibit.
EIGRP has been configured on all links. The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the links to R4. When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?
- A. R1 forwards the traffic to R3 in order to reach R2
- B. R1 forwards the traffic to R3, but R3 drops the traffic
- C. R1 load-balances across the paths through R3 and R4 to reach R2
- D. R1 has no route to R2 and drops the traffic
Answer: D
Explanation:
The EIGRP stub routing feature will prevent the remote device from advertising core routes back to the distribution devices. Routes learned by the remote device from Distribution 1 will not be advertised to Distribution 2. Therefore, Distribution 2 will not use the remote device as a transit for traffic destined to the network core https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_eigrp/configuration/15-mt/ire-15-mt-book/ire-eigrp-stub-rtg.html
