NEW QUESTION # 251
During IPv6 deployment in a legacy network, what must be considered for older Layer 2 switches? (Choose two)
Answer: B,E
Explanation:
#Explanation:
* C: IPv6 functions at Layer 3, and Layer 2 switches (which do not inspect or modify Layer 3 headers) typically forward IPv6 frames transparently just like IPv4-unless enhanced services are needed.
* D: For efficient IPv6 multicast handling (e.g., neighbor discovery, multicast services), switches should support MLD snooping (equivalent to IGMP snooping for IPv4).
Incorrect options:
* A, B, E: DHCPv6 snooping, ND snooping, and ICMPv6 snooping are not standard or widely implemented features in Layer 2 devices. They're also unnecessary for basic IPv6 forwarding.
NEW QUESTION # 252
Company XYZ is designing the network for IPv6 security and they have these design requirements:
A switch or router must deny access to traffic from sources with addresses that are correct, but are topologically incorrect Devices must block Neighbor Discovery Protocol resolution for destination addresses that are not found in the binding table.
Which two IPv4 security features are recommended for this company? (Choose two)
Answer: A,B
NEW QUESTION # 253
Which two features are advantages of SD-WAN compared to MPLS-based connectivity? (Choose two.)
Answer: A,E
NEW QUESTION # 254
Refer to the exhibit.
A company named XYZ needs to apply security policies for end-user browsing by installing a secure web proxy appliance. All the web traffic must be inspected by the appliance, and the remaining traffic must be inspected by an NGFW that has been upgraded with intrusion prevention system functionality. In which two ways must the routing be performed? (Choose two)
Answer: C,D
Explanation:
In this architecture:
* A secure web proxy is introduced to inspect and filter all web (HTTP/HTTPS) traffic.
* Remaining traffic (non-web) must pass through an NGFW with IPS capabilities.
* Both the web proxy and NGFW reside between the collapsed distribution/core and internet edge.
To enforce that all web traffic is directed to the proxy appliance for inspection and non-web traffic follows its usual path to the NGFW:
A). Policy-Based Routing (PBR) on the Collapsed Core
This allows traffic classification based on destination port (e.g., TCP 80/443) and selectively reroutes web traffic to the proxy. Non-web traffic continues toward the NGFW. PBR is essential here because traditional routing (based only on destination IP) would not differentiate between traffic types.
D). Static Routing on the Appliance
The proxy appliance must return the traffic back toward the NGFW for final processing and internet egress.
This is typically achieved using static routes on the proxy device, ensuring the return path sends packets back to the correct firewall interface for consistent inspection.
#B. Policy-based routing on the internet edge: Not applicable here, as rerouting must occur closer to the source (collapsed core), before traffic reaches the internet edge.
#C. Policy-based routing on firewalls: This adds unnecessary complexity. Firewalls should focus on enforcing security policies, not traffic redirection logic in this scenario.
This approach adheres to CCDE v3.1 best practices by separating policy enforcement functions and enabling scalable, deterministic traffic flow through layered security appliances.
