NEW QUESTION # 137
Your network operations team is deploying Access Control Lists (ACLs) across your Internet gateways. They wish to place an ACL inbound on the Internet gateway interface facing the core network (the "trusted" interface). Which IP address would the ACL need for traffic sourced from the inside interface, to match the source address of the traffic?
- A. inside local
- B. outside global
- C. outside local
- D. inside global
Answer: D
Explanation:
When an ACL is applied inbound on the Internet gateway interface facing the internal (trusted) network, the source IP address seen in the ACL will be the address after NAT translation has been applied to outbound traffic. This is called the inside global address:
* Inside global = Public IP assigned by NAT to inside traffic for external use.
* Inside local = Internal IP address prior to NAT.
Why other options are incorrect:
* B, D: Outside addresses refer to external devices, not internal traffic.
* C: Inside local is seen before NAT, not after.

NEW QUESTION # 139
An MPLS service provider is offering a standard EoMPLS-based VPLS service to Customer A. providing Layer 2 connectivity between a central site and approximately 100 remote sites. Customer A wants to use the VPLS network to carry its internal multicast video feeds which are sourced at the central site and consist of 20 groups at Mbps each. Which service provider recommendation offers the most scalability?
- A. Replace VPLS with a Layer 3 MVPN solution to carry the streams between sites
- B. Enable snooping mechanisms on the provider PE routers.
- C. Use a mesh of GRE tunnels to carry the streams between sites
- D. EoMPLS-based VPLS can carry multicast traffic in a scalable manner
Answer: B
NEW QUESTION # 140
A service provider recently migrated to an SD-WAN solution for delivering WAN connections to its customers. One of the main challenges with the SD-WAN deployment is that branch site volume increases every year, which causes management complexity. Which action resolves the issue?
- A. Build a service orchestration platform on top of the network controller.
- B. Adopt a well-structured SD-WAN service management lifecycle model.
- C. Set up a dedicated team to monitor and provision new customers.
- D. Implement a scalable network management system to manage all sites.
Answer: A
Explanation:
* C (Service orchestration platform):As branch scale increases, orchestration platforms automate multi- site deployment, configuration, and policy management. They integrate with controllers and external systems to reduce manual intervention, improve scalability, and enforce service consistency across thousands of locations.
Other options explained:
* A: Management systems assist monitoring but don't address provisioning complexity.
* B: Lifecycle models guide processes but are not technical automation solutions.
* D: Manual teams are not scalable for high-volume growth.
NEW QUESTION # 141
Which technology is an open-source infrastructure automation tool that automates repetitive tasks for users who work in networks such as cloud provisioning and intraservice orchestration?
- A. Contrail
- B. Jinja2
- C. Ansible
- D. Java
Answer: C
NEW QUESTION # 142
A software-defined networking (SDN) controller learns network topology information by using BGP link- state sessions with the route reflectors of an MPLS-enabled network. The controller then uses the topology information to apply on-demand traffic policies to the network through a protocol that is supported from all Layer 3 routers. Each policy is represented as a RIB entry in the control plane of the router. Which SDN model has been implemented?
- A. SDN traffic engineering
- B. SDN hybrid
- C. SDN centralized
- D. SD-WAN
Answer: C
Explanation:
This scenario describes a centralized control mechanism where:
* The SDN controller learns the network topology using BGP Link-State (BGP-LS).
* The controller installs control-plane policies using protocols like PCEP or BGP.
* Policies are pushed centrally and result in new RIB entries at the routers.
This is the hallmark of a centralized SDN architecture:
* The controller has a global view and decision-making logic.
* Routers remain relatively simple in the control plane and act on instructions.
This aligns with CCDE v3.1 under the "Technology Comparisons and Use Cases" topic, where SDN models are compared:
* Centralized SDN (controller-driven)
* Distributed SDN (traditional)
* Hybrid (a blend of both, which is not represented here)
NEW QUESTION # 143
Which tool automates network implementation activities and shortens the implementation lifecycle?
- A. Conclusion
- B. Python
- C. LISP
- D. Java
Answer: B
Explanation:
* D (Python):Python is widely used for network automation, configuration management, and scripting tasks. It simplifies repeatable network changes, validation, and integration with controllers and APIs, reducing deployment time.
Other options explained:
* A: LISP is a routing protocol, not an automation tool.
* B: Java is a general-purpose language but not commonly used for network automation.
* C: "Conclusion" is not a tool.
NEW QUESTION # 144
Which two business areas support continuity during emergencies by understanding data flows and business processes? (Choose two)
- A. Centralized device management
- B. Decentralized device management
- C. BYOD policy
- D. Disaster recovery
- E. Business continuity
Answer: D,E
Explanation:
#Explanation:
* C: Disaster Recovery focuses on restoring services and data after a catastrophic event.
* E: Business Continuity is a broader framework ensuring operations can continue despite disruptions.
Both require knowledge of critical data flows and dependencies.
Other options:
* A & D: Device management is operational-not directly focused on emergency business continuity.
* B: BYOD is a policy concern related to access and security, not continuity.

NEW QUESTION # 146
Refer to the exhibit. Company XYZ BGP topology is as shown in the diagram. The interface on the LA router connected toward the 10.1.5.0/24 network is faulty and is going up and down, which affects the entire routing domain. Which routing technique can the network administrator use so that the rest of the network is not affected by the flapping issue?
- A. The LA administrator should use route dampening for the 10.1.5.0/24 network so that it does not get propagated when it flaps up and down.
- B. The LA administrator should use route aggregation to summarize the 10.1.4.0/24, 10.1.5 0/24,
10.1.6.0/24, and 10.1.7.0/24 networks toward Chicago. - C. The LA administrator should use route filtering to block the 10.1.5.0/24 network from getting propagated toward Chicago and New York.
- D. The Chicago administrator should use route filtering to block the 10.1.5.0/24 network from coming in from the LA router.
Answer: B
NEW QUESTION # 147
