Cisco Certified Design Expert (CCDE) Written Exam Sample Questions (Q108-Q113):

NEW QUESTION # 108
Which two points must network designers consider when designing a new network design or when evaluating an existing network design to help them understand the high-level design direction with regards to the security aspects? (Choose two)

A. Consider for only new network technologies and components
B. Consider organization's security policy standards
C. Consider Business objectives and goals
D. Consider for only multi-site networks

Answer: B,C

NEW QUESTION # 109
Refer to the exhibit. An engineer is designing the network for a multihomed customer running in AS 111 does not have any other Ass connected to it. Which technology is more comprehensive to use in the design to make sure that the AS is not being used as a transit AS?

A. Use the local preference attribute to configure your AS as a " non-transit " AS.
B. Configure the AS-set attribute to allow only routes from AS 111 to be propagated to the neighbor ASs.
C. Include an AS path access list to send routes to the neighboring ASs that only have AS 111 in the AS path field.
D. Include a prefix list to only receive routes from neighboring ASs.

Answer: C

NEW QUESTION # 110
Backups and mirror copies of data are part of RPO (Recovery Point Objective) strategies. If a business wants to reduce their CAPEX for disaster recovery, which solution is most applicable?

A. Renew backup software annually to get the newest version
B. Perform an annual cybersecurity assessment or penetration test
C. Migrate parts of or all the infrastructure to the cloud
D. Build a redundant infrastructure at another location

Answer: C

Explanation:
Comprehensive and Detailed Explanation:
* C: Moving workloads or backup/recovery functions to cloud platforms reduces capital expenditure by avoiding the cost of physical infrastructure, data centers, and maintenance. Cloud-based DRaaS (Disaster Recovery as a Service) offers scalability, resilience, and cost efficiency aligned with an OPEX model.
Other options:
* A and B are security and software lifecycle tasks, not cost-effective DR strategies.
* D increases CAPEX by building and maintaining additional infrastructure.

NEW QUESTION # 111
Sometimes SDN leverages various overlay networking technologies to create layer(s) of network abstraction.
What describes an overlay network?

A. It is responsible for the delivery of packets; NAT- or VRF-based segregation is required
B. It transmits packets that traverse over network devices like switches and routers
C. It encapsulates packets at source and destination, which incurs additional overhead
D. Packet delivery and reliability occurs at Layer 3 and Layer 4

Answer: C

Explanation:
B (Encapsulation at source and destination):Overlay networks encapsulate payloads inside another protocol (e.
g. VXLAN, GRE, MPLS), adding headers that enable separation from the underlay network while introducing minor overhead due to encapsulation.
Other options explained:
A: Describes underlay behavior.
C: Overlay encapsulation occurs independently of L3/L4 reliability.
D: NAT or VRF are isolation mechanisms but not how overlays function.

NEW QUESTION # 112
The line between security and compliance is easily blurred and is, to a large extent, a moving target Drag and drop each of the requirements on the left to the appropriate section on the right
