While the Software and APP online can be used on computers. When you find it hard for you to learn on computers, you can learn the printed materials of the 400-007 Exam Questions. What is more, you absolutely can afford fort the three packages. The price is set reasonably. And the Value Pack of the 400-007 practice guide contains all of the three versions with a more favourable price.

Cisco 400-007 exam covers a wide range of topics related to network design, including network protocols, network security, network virtualization, and network automation. It is a written exam that involves multiple-choice questions, and it is designed to test the candidate's ability to analyze complex network problems and provide effective solutions. 400-007 Exam is challenging and requires extensive preparation, but it is well worth the effort for those who want to advance their careers in the networking field.

Cisco Certified Design Expert (CCDE v3.0) Written Exam Sample Questions (Q111-Q116):

NEW QUESTION # 111
Which aspect of BGP-LS makes it scalable in large networks when multiarea topology information must be gathered?

A. Transmit flow control
B. Open-loop flow control
C. Hardware flow control
D. TCP-based flow control

Answer: D

Explanation:
BGP-LS (BGP Link-State) distributes IGP topology information using BGP. When used in multi-area or multi-domain networks, BGP-LS allows for a centralized controller to receive topology information in a scalable way. BGP inherently runs over TCP, which provides reliable, ordered delivery using built-in flow control mechanisms.
The use ofTCP-based flow controlensures that even in large-scale networks where significant link-state information is exchanged, the flow of data between BGP peers remains efficient, controlled, and buffered according to the receiver's capacity. This makes it ideal for transporting massive amounts of LS data across wide areas and into SDN controllers for applications like traffic engineering or path computation.
Why other options are incorrect:
* A, B, and C refer to mechanisms that are not implemented or leveraged by BGP.
* TCP-based flow control is the only valid flow-control mechanism used in BGP sessions.

NEW QUESTION # 112
Two routers R1 and R2 are directly connected through an Ethernet link Both routers are running OSPF. OSPF has been registered with BFD and BFD is running in asynchronous mode with the echo function enabled Which two actions occur that are related to the echo function? (Choose two)

A. BFD control packets are sent at a higher pace because the echo function is enabted
B. DUMPS BFD sessions at either end actively participate in the forwarding of echo packets
C. Only BFD control packets are sent from forwarding engines along the Layer 2 path to perform detection
D. BFD control packets are sent at a slower pace because the echo function is enabled
E. BFD echo packets are sent from forwarding engines along the Layer 2 path to perform detection

Answer: D,E

NEW QUESTION # 113
Which aspect of BGP-LS makes it scalable in large network when multiarea topology information must be gathered?

A. open-loop flow control
B. hardware flow control
C. TCP-based flow control
D. transmit flow control

Answer: D

NEW QUESTION # 114
Company ABC wants to minimize the risk of users plugging unauthorized switches and hubs into the network. Which two features can be used on the LAN access ports to support this design requirement?
(Choose two.)

A. DTF
B. Root Guard
C. Loop Guard
D. BPDU Guard
E. PortFast

Answer: B,D

Explanation:
* D (Root Guard): Prevents unauthorized devices from becoming the STP root by blocking superior BPDUs on access ports.
* E (BPDU Guard): Immediately shuts down ports that receive unexpected BPDUs, protecting against accidental or malicious connection of switches to access ports.
Why other options are incorrect:
* A: Loop Guard protects against unidirectional link failures but not unauthorized devices.
* B: PortFast speeds up STP convergence on access ports but does not provide security.
* C: DTF (Dynamic Trunking Protocol) is not a security feature.

NEW QUESTION # 115
The controller has a global view of the network, and it can easily ensure that the network is in a consistent and optimal configuration. Which two statements describe a centralized SDN control path? (Choose two.)

A. It centralized controller can support all southbound APIs, which allows for easy integration with legacy equipment.
B. It is highly-available by design with no single-point-of-failure risks present.
C. It significantly improves the latency when performing reactive handling of PACKET_IN events.
D. Integrating smart NIC capabilities on the local host level is made easier through rest APIs.
E. Scaling of the centralized controller cluster is challenging for services like DHCP and load-balancing.

Answer: A,E
