NEW QUESTION # 46
Refer to the exhibit.
An engineer has been asked to redesign the traffic flow toward AS 111 coming from AS 500. Traffic destined to AS 111 network 91.7.0.0/16 should come in via AS 100, while traffic destined to all other networks in AS
111 should continue to use the existing path. Which BGP attributes are best suited to control this inbound traffic coming from BGP AS 500 into the 91.7.0.0/16 network?
- A. Use local preference on R1 for the networks that AS 500 advertises to AS 111.
- B. Prepend AS path for the 91.7.0.0/16 network and set it for neighbor in AS 200.
- C. Set higher MED for neighbor in AS 100 to influence incoming traffic for the 91.7.0.0/16 network.
- D. Use extended community for the 91.7.0.0/16 network, not advertising it to the bi-lateral peer.
Answer: B
Explanation:
* Inbound traffic engineering is best controlled by manipulating how external ASes view your routes.
* AS path prepending on the 91.7.0.0/16 prefix towards AS 200 makes AS 500 prefer the less-prepended path through AS 100.
* This allows granular inbound control for that specific prefix while leaving the rest of the traffic unchanged.
Why other options are incorrect:
* B: Extended community is not used for direct inbound path manipulation.
* C: Local preference affects outbound traffic, not inbound path selection by remote ASes.
* D: MED is only compared between the same AS; it won't affect AS 500's choice.

NEW QUESTION # 53
The major business applications of an enterprise are largely monolithic and hard-coded. As part of a major modernization and overhaul of the applications, the goal is to move to a modular and containerized application architecture model. At the same time, decoupling from the hardware is desired to move to an on- demand provisioning. However, the CyberOps team mandated that the final architecture must provide the same security levels as an air-gapped data center. Which cloud architecture meets these requirements?
- A. Public cloud
- B. PaaS
- C. IaaS
- D. Hybrid cloud
- E. Private cloud
Answer: E
Explanation:
Private cloud architecture provides:
* On-demand provisioning and decoupling from hardware
* Security controls under enterprise ownership
* Strong isolation - comparable to an air-gapped model if fully controlled on-premises or in a dedicated hosted environment While public or hybrid clouds offer flexibility, they cannot guarantee security parity with air-gapped systems unless significant additional controls are implemented. Private cloud supports containerized architectures and modern DevOps pipelines, while keeping the data plane within enterprise boundaries.
This aligns with CCDE's cloud design principles - balancing modernization goals with strict compliance and cybersecurity mandates.

- E. Scaling of the centralized controller cluster is challenging for services like DHCP and load-balancing.
Answer: A,E
Explanation:
* A (Scaling challenges for services):Centralized SDN controllers may experience scalability challenges for distributed services like DHCP and load balancing since these often require real-time responsiveness and distributed service locality.
* D (Latency in reactive handling):Centralized controllers may introduce additional latency during reactive PACKET_IN event handling as control decisions traverse the control plane before forwarding happens.
Other options explained:
* B: Centralized controllers still present failure domain risks; high-availability must be explicitly designed.
* C: Smart NICs operate primarily at the host level, often independently of centralized SDN controllers.
* E: Legacy equipment often lacks support for many SDN southbound APIs.

NEW QUESTION # 60
A customer has a functional requirement that states HR systems within a data center should be segmented from other systems that reside in the same data center and same VLAN. The systems run legacy applications by using hard-coded IP addresses. Which segmentation method is suitable and scalable for the customer?
- A. Data center perimeter firewalling
- B. Transparent firewalling
- C. Routed firewalls
- D. VACLs on data center switches
Answer: B
Explanation:
* C (Transparent firewalling):Transparent (Layer 2) firewalls operate at the data link layer and allow segmentation and inspection of intra-VLAN traffic without requiring changes to the existing IP addressing. This is ideal for legacy environments where IP addresses are hard-coded, while still providing fine-grained security policies between applications in the same subnet.
Other options explained:
* A: Perimeter firewalls cannot segment east-west traffic within a VLAN.
* B: VACLs provide basic filtering but are not as scalable or flexible as transparent firewalls for stateful inspection.
* D: Routed firewalls require Layer 3 boundaries, which would conflict with hard-coded IP design.
NEW QUESTION # 61
According to the CIA triad principles for network security design, which principle should be priority for a Zero Trust network?
- A. categorization of systems, data, and enterprise BYOD assets that are connected to network zones based on individual privacy needs
- B. requirement for data-in-motion encryption and 2FA authentication
- C. ensuring that authorized users have high-availability system access from defined zones to defined systems or zones
- D. requirement for data-at-rest encryption for user identification within the VPN termination hardware
Answer: B
Explanation:
* A (Encryption + strong authentication) aligns most closely with Zero Trust's emphasis on always verifying identity and protecting data as it moves across untrusted networks.
* Data-in-motion encryption ensures confidentiality, and two-factor authentication ensures strict identity verification.
Why other options are incorrect:
* B: Data-at-rest encryption is important but not as critical as controlling data in motion for Zero Trust.
* C: Categorization helps in segmentation but is not the core Zero Trust principle.
* D: High availability is a design requirement, not the primary Zero Trust security control.

NEW QUESTION # 64
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?
- A. IPsec
- B. DTLS
- C. GRE
- D. TLS
Answer: B
Explanation:
* DTLS (Datagram Transport Layer Security) is the most optimized overlay protocol for SDWAN deployments over public internet, especially when NAT traversal is required.
* It combines security similar to TLS while using UDP, which handles packet loss, jitter, and reordering better than TCP-based TLS.
* DTLS is natively supported in most SDWAN solutions for encrypted transport across NAT environments without complex configurations.
* It allows optimal performance on unreliable or high-latency networks while maintaining strong security standards.
Why other options are incorrect:
* A (TLS): Uses TCP, less suited for networks with packet loss or reordering.
* C (IPsec): Requires additional NAT traversal mechanisms like NAT-T and may not handle unreliable underlay as effectively as DTLS.
* D (GRE): Tunneling protocol without native encryption.
