NEW QUESTION # 195
The goal for any network designer is to strive to build a resilient network that adapts to changing conditions rapidly with minimal impact on the services running over the network. A resilient network can adapt to failures, but which soft failure can be harder to define and detect?
- A. a network that is not running in an optimal way
- B. a network or service that experiences outages
- C. a network with operational challenges due to lack of skills
- D. a network which does not solve complexity issues
Answer: A
Explanation:
A network that is not running in an optimal way represents a soft failure because it may not experience complete outages, but it can suffer from performance degradation, increased latency, or other inefficiencies that can be difficult to detect and define. Unlike a hard failure, such as an outage, an optimal performance issue can often go unnoticed until it impacts services significantly.

NEW QUESTION # 197
With SDN, network administrators can automate many tasks, such as configuring network policies, traffic flows, and security settings. This automation can significantly reduce the time and effort required to manage and maintain networks.
Which focus area of task automation can the network engineers use to greatly reduce manual effort for everyday network changes?
- A. individual activities
- B. on demand
- C. end-to-end outcome
- D. training and enablement
Answer: C
Explanation:
End-to-end outcome automation focuses on automating entire workflows rather than individual tasks, which greatly reduces manual effort and ensures consistency in everyday network changes.
NEW QUESTION # 198
Company XYZ has two offices connected to each other over unequal redundant paths and they are running OSPF as the routing protocol An external network architect recommends BFD for OSPF Which effect would BFD have in the case of a link failure?
- A. It would optimize the route summarization feature of OSPF
- B. It would detect that the neighbor is down in a subsecond manner
- C. It would drop the dead per detection time to a single hello
- D. It would keep an alternate path ready in case of a link failure
Answer: B
NEW QUESTION # 199
An engineer must design a network for a company that uses OSPF LFA to reduce loops. Which type of loop would be reduced by using this design?
- A. REP
- B. DTP
- C. Micro loops
- D. STP
Answer: C
Explanation:
* B (Micro loops):OSPF Loop-Free Alternates (LFA) pre-calculate backup next-hops to reduce transient micro loops during the convergence process when primary routes fail.
Other options explained:
* A: DTP relates to trunk negotiation, not loop prevention.
* C: STP handles Layer 2 loops.
* D: REP is a Cisco Layer 2 redundancy protocol, unrelated to OSPF loop prevention.
NEW QUESTION # 200
A business invests in SDN and develops its own SDN controller that, due to budget constraints, runs on a single controller. The controller actively places an exclusive lock on the configuration of the devices to ensure it is the only source of changes to the environment. What is the result if the controller fails?
- A. The control plane is unavailable until the controller is restored.
- B. Manual changes are only possible until the controller is restored.
- C. If a device fails, the configuration backup is unavailable.
- D. All device configurations are in read-only mode until the controller is restored.
Answer: A
Explanation:
* B (Control plane is unavailable):In centralized SDN models where the controller has full exclusive configuration authority (lock), controller failure results in loss of control-plane functionality. No new flows can be programmed, and dynamic traffic adjustments cannot occur until the controller is restored.
Other options explained:
* A: Devices typically continue forwarding existing flows but are not in read-only config mode.
* C: Backups may still be available independently.
* D: Manual changes are often restricted to preserve state consistency.

The new design should use a flavor of PIM that forwards traffic using SPT.
Which technology meets this requirement?
- A. PIM-SSM
- B. BIDIR-PIM
- C. PIM-SM
- D. PIM-DM
Answer: A
Explanation:
PIM SSM uses the PIM sparse-mode functionality to create an SPT between the receiver and the source, but builds the SPT without the help of an RP.
NEW QUESTION # 205
Refer to the exhibit.
Which impact of using three or more ABRs between the backbone area and area 1 is true?
- A. Multiple ABRs reduce the CPU processing on each ABR due to splitting prefix advertisement
- B. In a large-scale network LSA replication by all ABRs can cause serious scalability issues
- C. In a large-scale network multiple ABRs can create microloops
- D. Prefixes from the non-backbone area are advertised by one ABR to the backbone
Answer: C
Explanation:
In OSPF multi-area designs with multiple ABRs, when there is temporary inconsistency between the ABRs' type-3 summary LSAs, microloops can occur during convergence. These loops happen due to slight differences in LSA arrival and SPF calculations across routers while the network is converging.
* Microloops are short-lived but can cause brief packet loss.
* This becomes more likely as the number of ABRs grows and IGP flooding domains increase.
CCDE v3.1 emphasizes careful ABR design and possible use of loop avoidance mechanisms (e.g., LFA, microloop prevention techniques) in large-scale OSPF designs.
Why other options are incorrect:
* A: LSA flooding in OSPF scales well; type-3 LSA replication is not the primary scalability issue.
* B: ABRs process all LSAs regardless; load is not split.
* D: Multiple ABRs all independently summarize and advertise into the backbone.
