Question #21
Refer to the exhibit. An engineer is preparing to implement data plane security configuration.
Which statement about this configuration is true?
Question #22
Which MPLS design attribute can you use to provide Internet access to a major customer through a separate dedicated VPN?
- AThe Internet gateway router is connected as a PE router to the MPLS backbone.
- BThe CE router supports VRF-Lite and the full BGP routing table.
- CThe Internet gateway inserts the full Internet BGP routing table into the Internet access VPN.
- DThe customer that needs the Internet access service is assigned to the same RTs as the Internet gateway.
Correct Answer:
D
D
GPT-4o - Answer
Assigning the same Route Targets (RTs) to the customer as those used by the Internet gateway is a smart move in MPLS design for dedicated Internet access. This method simplifies the routing process and ensures that specific Internet routes are conveyed efficiently between the gateway and the customer's network, using VPN route-target communities. Normalizing RTs between customer and Internet access services provides a clean and effective way to integrate and manage these services within the MPLS environment.
Question #24
Refer to the exhibit. A network engineer is configuring customer edge routers to finalize a L2VPN over MPLS deployment. Assume that the AToM L2VPN service that connects the two CEs is configured correctly on the service provider network.
Which action causes the solution to fail?
Question #25
An engineer working for telecommunication company needs to secure the LAN network using a prefix list.
Which best practice should the engineer follow when he implements a prefix list?
Which best practice should the engineer follow when he implements a prefix list?
- AAn engineer must identify the prefix list with a number only.
- BThe final entry in a prefix list must be /32.
- CAn engineer must include only the prefixes for which he needs to log activity.
- DAn engineer must use nonsequential sequence numbers in the prefix list so that he can insert additional entries later.
Correct Answer:
D
D
GPT-4o - Answer
Using nonsequential sequence numbers when implementing a prefix list is indeed a best practice. This approach provides flexibility for making adjustments without the need to overhaul the entire list. It allows seamless integration of new entries at any point, accommodating network growth and changes without disrupting the established list. Always plan for the future when designing network architectures, and this method supports easy updates and scalability.
Question #26
Refer to the exhibit. Which effect of this configuration is true?
Question #27
Refer to the exhibit. Which three outcomes occur if the prefix list is added to the neighbor? (Choose three.)
Question #28

Question #29
What does DWDM use to combine multiple optical signals?
- AIP protocols
- Bwavelength
- Ctime slots
- Dfrequency
Correct Answer:
B
B
GPT-4o - Answer
DWDM, or Dense Wavelength Division Multiplexing, efficiently combines multiple optical signals using different wavelengths, not frequencies or time slots. This utilization of unique wavelengths allows for transmitting numerous signals simultaneously over the same optical fiber without interference, significantly enhancing bandwidth and communication capabilities. It stands as one of the core techniques in high-capacity fiber optic networks.
Question #30
Refer to the exhibit. A network operator recently configured BGP FlowSpec for the internal IT network. What will be inferred from the configuration deployed on the network?
