NEW QUESTION # 218
Which two mechanisms avoid suboptimal routing in a network with dynamic mutual redistribution between multiple OSPFv2 and EIGRP boundaries? (Choose two.)
Answer: A,D
Explanation:
Mutual redistribution between different routing protocols can cause routing loops and suboptimal routing due to:
Route feedback loops (routes being re-imported back into the originating protocol).
Inconsistent administrative distances (AD) leading to selection of suboptimal paths.
Two key mechanisms avoid these issues:
A). Administrative Distance (AD) manipulation: Ensures that one protocol is consistently preferred over the other when duplicate routes exist.
C). Route tagging: Assigns tags to redistributed routes to identify the source of the route and prevent re- importation (looping) into the originating protocol.
These methods align with CCDE v3.1 principles for multi-protocol control plane design and stability.
Why other options are incorrect:
B and F: Matching routes or process IDs do not directly prevent loops or suboptimal routing.
D is a duplicate of C.
E: Filtering helps but is reactive, not a comprehensive prevention mechanism.

NEW QUESTION # 219
Which three Cisco products are used in conjunction with Red Hat to provide an NFVi solution? (Choose three.)
Answer: A,B,F
Explanation:
Cisco NFVi (Network Function Virtualization Infrastructure) solutions integrate with Red Hat's virtualization stack using:
* C. Cisco Nexus switches: Provide data center network fabric.
* D. Cisco UCS: Provides the compute platform for NFV workloads.
* F. Cisco Virtual Network Functions: The software-based network functions running on NFVi (e.g.
virtual routers, firewalls, etc.).
Why other options are incorrect:
* A: Cisco Prime Service Catalog is a management tool, not part of NFVi infrastructure.
* B: Cisco Open vSwitch is not a Cisco product (Open vSwitch is open-source).
* E: Cisco Open Container Platform is not part of the NFVi reference solution in conjunction with Red Hat.

NEW QUESTION # 220
Company XYZ has a hub-and-spoke topology over an SP-managed infrastructure. To measure traffic performance metrics, they implemented IP SLA senders on all spoke CE routers and an IP SLA responder on the hub CE router. What must they monitor to have visibility on the potential performance impact due to the constantly increasing number of spoke sites?
Answer: B
NEW QUESTION # 221
A large enterprise customer has a single router that uses two active/active 10-Mbps internet links in one of its offices. Each link currently handles approximately 7 Mbps of traffic, which is close to the full link capacity.
When a link fails, the failure leads to significantly degraded performance of all applications. Static routing is used. The current ISP cannot deliver additional bandwidth capacity on the existing links. The customer needs a network design that is resistant to failure, but does not increase CAPEX. Which solution should be proposed to the customer?
Answer: C
NEW QUESTION # 222
An organization that upgraded their system 10 years ago is now facing issues with their applications in the core network. Support teams have shared their findings in which some of the hardware and links needs to be upgraded to support newly provisioned bandwidth hungry applications. The design team has started working on the new design and has also requested to provision some of the application and network services in the cloud to immediately overcome current issues.
Which service type fits this use case?
Answer: D
Explanation:
Network as a Service (NaaS) allows organizations to provision network and application services from the cloud, providing immediate scalability and agility without requiring hardware refresh. This fits the use case of offloading bandwidth-hungry applications and network functions to the cloud while upgrading legacy infrastructure.
