Cisco Certified Design Expert (CCDE) Written Exam 400-007 Prüfungsfragen mit Lösungen (Q82-Q87):

82. Frage
A private cloud is accessed over the private IT network infrastructure that is potentially vulnerable to violations, data leaks, and man-in- the-middle attacks. The security team is evaluating the following solutions to address the challenges:
*Encrypt data at rest and in transition.
*Use strong identity and access management (IAM) capabilities.
*Communicate the inherent data security risks to your customers and end-users.
Assuming that adoption of a hybrid cloud model is likely to occur within the next 12 months, which two solutions can also help provide protection in a hybrid cloud environment? (Choose two.)

Antwort: A,B


83. Frage
Drag and drop the descriptions from the left onto the corresponding categories on the right Not all options are used

Antwort:

Begründung:

Explanation:
Port Numbers
* # It does not consume many resources.
* # It does not implement the application-layer payload, so it does not compromise the users ' privacy.
Deep Packet Inspection
* # Signatures must be kept up to date because the applications change very frequently.
* # Encryption makes this method impossible in many cases.
Statistical Classification
* # It very often uses machine learning algorithms.
* # It can detect the class of yet unknown applications.


84. Frage

Refer to the exhibit. A service provider has a requirement to use Ethernet OAM to detect end-to-end connectivity failures between SP-SW1 and SP-SW2. Which two ways to design this solution are true?
(Choose two)

Antwort: A,E

Begründung:
In service provider Ethernet transport environments such as VPLS, Ethernet OAM (Operations, Administration, and Maintenance) is used to provide fault detection, monitoring, and troubleshooting capabilities. The two relevant components here are:
A (Unicast heartbeat messages between MEPs): Maintenance End Points (MEPs) are configured at the edges of the OAM domain (SP-SW1 and SP-SW2). Heartbeat messages can be used to proactively monitor and detect loss of continuity between the endpoints.
B (Enable Connectivity Fault Management): CFM (IEEE 802.1ag) provides end-to-end fault detection, continuity check messages (CCMs), loopback, and link trace mechanisms that operate between MEPs at Layer 2. CFM enables proactive detection of failures and service-level assurance across the provider's Ethernet segment.
Other options explained:
C: Upward MEPs are not applicable here since these are typically used for customer-facing or hierarchical maintenance domains.
D: E-LMI (Ethernet Local Management Interface) operates between CE and PE for service activation-not applicable for SP-SW to SP-SW fault detection across VPLS.
E: LLDP (Link Layer Discovery Protocol) is for neighbor discovery on directly connected interfaces-not suitable for end-to-end fault detection across a VPLS domain.
This design solution aligns fully with CCDE v3.1 principles for service provider Layer 2 VPN design and Ethernet OAM integration.


85. Frage
Drag and Drop Question
Drag the components that are part of the CIA triad to the correct target on the right. Not all components are used.

Begründung:


86. Frage
When an SDN-based model is used to transmit multimedia traffic, which aspect should an architect consider while designing the network?

Antwort: A

Begründung:
* A (QoE estimation): In SDN-based designs, particularly for multimedia traffic (voice, video, streaming), Quality of Experience (QoE) estimation is crucial to ensure end-user satisfaction. SDN can dynamically allocate resources based on real-time measurements of packet loss, jitter, delay, and other QoE indicators to maintain service quality.
Other options explained:
* B: Security is always important but not unique to multimedia design.
* C: Traffic patterns are part of capacity planning but secondary to QoE for multimedia.
* D: Flow forwarding is handled by the SDN controller but does not directly address multimedia quality.
