Cisco Certified Design Expert (CCDE) Written Exam Sample Questions (Q363-Q368):

NEW QUESTION # 363

Refer to the exhibit A customer network design team is planning a migration from a legacy TDM-based L2VPN to an MPLS-based L3VPN Migration is planned in a phased approach:
*OSPF backbone Link between HUB A and HUB B sites to be migrated to eBGP
*Spoke A2 and Spoke B1 will be migrated to the L3VPN
Which solution design can be considered to avoid routing loops during backbone link migration

Answer: B


NEW QUESTION # 364
A company is adopting IPv6 in a dual-stack campus network. The first IPv6-only application is now hosted in the data center. To prevent a malicious user from masquerading as the IPv6 default gateway, which two mechanisms should be used? (Choose two)

Answer: D,E

Explanation:
#Comprehensive and Detailed Explanation (CCDE v3.1 aligned):
* A. IPv6 RA Guard:This feature helps mitigate rogue router advertisements (RAs), which attackers can use to spoof the default gateway in an IPv6 environment. RA Guard drops unauthorized or unexpected RAs at the access layer switch ports, preventing malicious devices from advertising themselves as routers.
* E. Port ACLs (PACLs):Port-based ACLs can restrict which devices are allowed to send or receive RA packets on switch ports. By tightly controlling which sources can send traffic (including RA messages), port ACLs help prevent spoofing attempts.
Other Options:
* #B. IPv6 Snooping:Not a standard or widely supported security feature; it is sometimes used synonymously with device tracking but is not a direct mitigation for spoofed RAs.
* #C. IPv6 Device Tracking:Useful for monitoring IP-to-MAC bindings, but it does not prevent spoofing or gateway impersonation.
* #D. IPv6 Address Glean:Primarily used for learning IPv6 addresses from traffic for things like DHCPv6 relay; not a security feature.
CCDE Blueprint Alignment:
Topic: Security, automation, and policy integration in design
Subdomain: IPv6 security, access control, rogue device prevention.

NEW QUESTION # 365
IPFIX data collection via standalone IPFIX probes is an alternative to flow collection from routers and switches. Which use case is suitable for using IPFIX probes?

Answer: C

Explanation:
* IPFIX probes can perform deep flow inspection beyond what routers/switches natively collect, making them well suited for security monitoring (DDoS detection, anomaly detection, intrusion attempts).
* Probes can extract Layer 7 information unavailable from normal router flow records.
Why other options are incorrect:
* A, C, D: Can also be done using router-integrated flow exports; dedicated probes are primarily deployed for advanced security visibility.
