An enterprise network has two core routers that connect to 200 distribution routers and uses full-mesh IBGP peering between these routers as its routing method. The distribution routers are experiencing high CPU utilization due to the BGP process. Which design solution is the most cost effective?
Select an option, then click Submit answer.
Implement route reflectors on the two core routers
Increase the memory on the core routers
Implement e BGP between the core and distribution routers
Increase the memory on the distribution routers
Increase bandwidth between the core routers
You are designing the QoS policy for a company that is running many TCP-based applications. The company is experiencing tail drops for these applications. The company wants to use a congestion avoidance technique for these applications. Which QoS strategy can be used to fulfill the requirement?
Select an option, then click Submit answer.
weighted fair queuing
weighted random early detection
low-latency queuing
first-in first-out
You are using iSCSI to transfer files between a 10 Gigabit Ethernet storage system and a 1 Gigabit Ethernet server The performance is only approximately 700 Mbps and output drops are occurring on the server switch port. Which action will improve performance in a cost-effective manner?
Select an option, then click Submit answer.
Change the protocol to CIFS.

A service provider recently migrated to an SD-WAN solution for delivering WAN connections to its customers. One of the main challenges with the SD-WAN deployment is that branch site volume increases every year, which causes management complexity. Which action resolves the issue?
Select an option, then click Submit answer.
Implement a scalable network management system to manage all sites.
Adopt a well-structured SD-WAN service management lifecycle model
Build a service orchestration platform on top of the network controller
Set up a dedicated team to monitor and provision new customers
SDWAN networks capitalize the usage of broadband Internet links over traditional MPLS links to offer more cost benefits to enterprise customers. However, due to the insecure nature of the public Internet, it is mandatory to use encryption of traffic between any two SDWAN edge devices installed behind NAT gateways. Which overlay method can provide optimal transport over unreliable underlay networks that are behind NAT gateways?
Select an option, then click Submit answer.
TLS
DTLS
IPsec
GRE
You are designing a network running both IPv4 and IPv6 to deploy QoS Which consideration is correct about the QoS for IPv4 and IPv6?
Select an option, then click Submit answer.
IPv4 and IPv6 traffic types can use use queuing mechanisms such as LLQ, PQ and CQ.
IPv6 packet classification is only available with process switching, whereas IPv4 packet classification is available with both process switching and CEF.
IPv6 and IB/4 traffic types can use a single QoS policy to match both protocols
Different congestion management mechanisms need to be used for IPv4 and IPv6 traffic types
This free practice test covers the Cisco Certified Design Expert (CCDE v3.0) (400-007) exam from Cisco. You will find 15 free questions, drawn from the full Study4Pass practice set of 266 questions for this exam. The free sample includes 7 single-answer, 6 multiple-answer and 2 drag-and-drop questions — the same mix of formats you will meet in the full set. The questions follow the same topic balance as the real exam: Network Fundamentals, Network Security, Routing Protocols and Switching Fundamentals. The Cisco 400-007 exam is a certification exam that tests a candidate's knowledge and skills related to the Cisco Certified Network Professional (CCNP) certification.
The target audience of Cisco 400-007 exam is professional who want to become certified in the CCIE Service Provider certification. The prerequisite for Cisco 400-007 Exam is to have a valid CCNP Routing and Switching certification.
Use the sample the way you would use the real thing: answer each question on your own first, then open the explanation and make sure you understand why the right answer is right. That habit — reasoning instead of memorizing — is what carries over to exam day. When a topic keeps tripping you up, that is your study plan telling you where to go next.
When you finish the sample, do not just count the score — read it. Every missed question names a topic, and the full set lets you train that topic on its own until it stops costing you marks. That loop of test, review and targeted practice is how this set is designed to be used, from the first free question to the last simulation.
Inside the full 400-007 practice set:
Pick an answer for each question and check it straight away — the correct answer and a full explanation appear under the question. There is no time limit and nothing to sign up for. When an explanation is not enough, use Ask AI: this is an AI-Enabled practice test, and Ask AI explains the concept behind the question in plain language. Ready for more? The full 266-question set adds a timed Exam Simulation mode, topic training for your weak areas, and a flagged-question review, so you can practise the way the real exam feels.
