NEW QUESTION # 126
Refer to the exhibit.
The WAN network of the General Bank of Greece has experienced several outages It takes too long to activate a new branch site The networking department of the bank plans to upgrade the legacy end-of-life WAN network with a new flexible manageable, and scalable in-house solution The number of branches will increase exponentially in the next fiscal year The CTO states that the bank's mam goal is OPEX reduction The network engineering team prepares a table to evaluate the available options Which WAN technology can be used for the solution?
- A. SD-WAN over L3VPN
- B. Managed SD-WAN
- C. DMVPN over L3VPN
- D. SD-WAN over L2VPN
Answer: B
NEW QUESTION # 127 
Refer to the exhibit. An architect must design an enterprise WAN that connects the headquarters with 22 branch offices. The number of remote sites is expected to triple in the next three years. The final solution must comply with these requirements:
* Only the loopback address of each of the enterprise CE X and Y routers must be advertised to the interconnecting service provider cloud network.
* The transport layer must carry the VPNv4 label and VPN payload over the MP-BGP control plane.
* The transport layer must not be under service provider control.
Which enterprise WAN transport virtualization technique meets the requirements?
- A. EIGRP Over the Top
- B. DMVPN per VRF
- C. Point-to-point GRE per VRF
- D. MPLS over BGP over multipoint GRE
Answer: D
Explanation:
* B (MPLS over BGP over mGRE):This design allows enterprises to run MPLS VPNs across their own infrastructure (Overlay VPN) while using MP-BGP for control plane distribution of VPNv4 routes. The mGRE tunnel structure allows scalability as branches grow, while MPLS VPN labels ensure traffic separation.
Other options explained:
* A: EIGRP OTT is not scalable for large VPN deployments.
* C: DMVPN per VRF becomes complex with high scale growth.
* D: Point-to-point GRE per VRF lacks scalability for 60+ sites.
NEW QUESTION # 128
Which two constraints of REST are important when building cloud-based solutions? (Choose two)
- A. Separation of resources from representation
- B. Migration of resources by representations
- C. Distribution of resources through platforms
- D. Hyper-scale as the engine of application state
- E. Self-descriptive messages
Answer: A,E
Explanation:
# Explanation:
* A: REST separates the resource (URI) from its representation (JSON, XML, etc.), allowing for flexible interfaces and abstraction in distributed systems like the cloud.
* E: RESTful communication relies on self-descriptive messages, enabling stateless communication- critical for scalable and resilient cloud-native design.
Other options:
* B, C, and D are not part of REST's formal constraints and misrepresent architectural principles.

Which two actions must be taken when assessing an existing wireless network implementation for its readiness to support voice traffic? (Choose two.)
- A. Identify frequent TX power changes.
- B. Check for high roaming delay.
- C. Check for latency over wireless.
- D. Check for high channel utilization.
- E. Check for uniform radio coverage across the floors.
Answer: B,E
Explanation:
* A (Roaming delay):Voice requires seamless roaming with minimal handoff delay to avoid call drops.
* B (Uniform radio coverage):Consistent signal coverage is essential for maintaining voice call quality throughout the facility.
Other options explained:
* C: High channel utilization affects capacity but not directly the initial readiness assessment.
* D: Latency is important but typically captured during ongoing performance testing, not pre-assessment.
* E: TX power changes indicate instability but are not primary readiness criteria.

Answer: A
NEW QUESTION # 135
Which mechanism enables small, unmanaged switches to plug into ports of access switches without risking switch loops?
- A. BPDU guard
- B. Root guard
- C. UDLD
- D. PortFast
Answer: A
Explanation:
When unmanaged switches are connected to access ports, there's a risk that they may start participating in Spanning Tree Protocol (STP) or introduce loops. BPDU Guard is the most effective mechanism to mitigate this risk:
* BPDU Guard disables a port immediately upon receiving any BPDU, ensuring that only end hosts (non- switch devices) are connected to access ports.
* This protects the stability of the STP topology by preventing accidental or malicious introduction of switches into the Layer 2 domain.
Other options explained:
* A (PortFast): Accelerates port transition to forwarding state but does not protect against loops caused by BPDUs.
* B (UDLD): Detects unidirectional physical link failures but not STP participation.
* C (Root guard): Prevents the connected device from becoming a root bridge but still allows BPDUs.

NEW QUESTION # 137
A network security team uses a purpose-built tool to actively monitor the campus network, applications, and user activity. The team also analyzes enterprise telemetry data from IPFIX data records that are received from devices in the campus network. Which action can be taken based on the augmented data?
- A. Integration with an incident response plan
- B. Adoption and improvement of threat-detection response
- C. Reduction in time to detect and respond to threats
- D. Asset identification and grouping decisions
Answer: C
Explanation:
* A (Faster detection and response):Telemetry like IPFIX enables real-time network visibility and anomaly detection, significantly improving Mean Time to Detect (MTTD) and Mean Time to Respond (MTTR).
Other options explained:
* B: IPFIX feeds data to incident response, but doesn't directly integrate plans.
* C: IPFIX improves detection but primarily reduces response time.
* D: Asset identification typically uses CMDB or inventory tools, not IPFIX alone.

NEW QUESTION # 141
A green data center is being deployed and a design requirement is to be able to readily scale server virtualization. Which IETF standard technology can provide this requirement?
- A. fabric path
- B. unified fabric
- C. data center bridging
- D. Transparent Interconnection of Lots of Links
Answer: D
Explanation:
Transparent Interconnection of Lots of Links (TRILL) is an IETF standard specifically designed to improve scalability, convergence, and loop prevention in data center environments while supporting virtualization at scale. TRILL replaces traditional Spanning Tree Protocol (STP) with a shortest path forwarding protocol, combining the benefits of routing with the simplicity of bridging.
TRILL uses IS-IS as its control plane protocol to calculate optimal paths dynamically, enabling better bandwidth utilization and faster failover-critical for server virtualization that demands highly available, resilient, and scalable Layer 2 networks.
Why other options are incorrect:
* A. Data Center Bridging (DCB) is a set of enhancements for Ethernet but doesn't directly address virtualization scaling.
* B. Unified Fabric combines storage and data traffic but is not IETF standardized and focuses on cabling consolidation.
* D. FabricPath is Cisco proprietary, not IETF standard.

[Business-Driven Design Approaches / Recovery Planning] For a company providing online billing systems, which strategy keeps RPO (Recovery Point Objective) as low as possible?
- A. Backup on external storage
- B. Spare onsite disks
- C. Cloud backup to mirror data
- D. Periodic snapshot of data
Answer: C
Explanation:
#Explanation:
* A: Cloud-based data mirroring offers near-real-time replication, keeping RPO near zero. This is essential for billing systems where even a small amount of data loss could be critical.
* B and D: Manual or local backups don't offer low RPO unless continuously synced.
* C: Snapshots are periodic and inherently result in a higher RPO due to the gap between intervals.

Other options:
* C: Management tools are for visibility-not enforcement.
* D: While useful, endpoint AV/firewalls act independently-not part of policy enforcement infrastructure.
* F: Web filters do not participate in initial access decisions.
