NEW QUESTION # 389
Company XYZ was not satisfied with the reconvergence time OSPF is taking. BFD was implemented to try to reduce the reconvergence time, but the network is still experiencing delays when having to reconverge. Which technology will improve the design?
Answer: A
NEW QUESTION # 390
An IT service provider is upgrading network infrastructure to comply with PCI security standards. The network team finds that 802.1X and VPN authentication based on locally-significant certificates are not available on some legacy phones. Which workaround solution meets the requirement?
Answer: A
Explanation:
* B (Enable phone VPN authentication based on end-user username and password):When legacy devices don't support certificate-based authentication, fallback to username/password provides a temporary workaround while maintaining PCI compliance, assuming strong credentials and secure tunnels are used.
Other options explained:
* A: Immediate hardware replacement may not be feasible.
* C: TLS 1.0 fallback violates PCI standards, which prohibit deprecated protocols.
* D: Clear text authentication is non-compliant with PCI requirements.
NEW QUESTION # 391
Refer to the exhibit.
Company XYZ must design a DMVPN tunnel between the three sites. Chicago is going to act as the NHS, and the company wants DMVPN to detect peer endpoint failures. Which technology should be used in the design?
Answer: B
Explanation:
In a DMVPN (Dynamic Multipoint VPN) design:
* One site (here, Chicago) functions as the Next Hop Server (NHS), which facilitates dynamic spoke-to- spoke tunnel establishment.
* DMVPN is based on multipoint GRE tunnels combined with NHRP (Next Hop Resolution Protocol).
* The ability to detect remote tunnel endpoint failures is essential for reliable routing convergence and tunnel restoration.
While GRE (Option C) is the encapsulation mechanism used in DMVPN, it does not inherently provide failure detection. Likewise, VPLS and L2TPv3 are Layer 2 VPN technologies and not applicable in DMVPN design.
To meet the requirement of peer failure detection, the correct mechanism is:
* B. IP SLA (Service-Level Agreement): This is a feature that actively monitors the health and reachability of tunnel endpoints through periodic probes (e.g., ICMP echo). When the peer becomes unreachable, routing protocol adjacencies can be withdrawn, and alternate paths selected.
Using IP SLA in a DMVPN design helps detect endpoint failure scenarios such as:
* A spoke going down unexpectedly
* Loss of return traffic
* Partial link failures
This design pattern is aligned with CCDE v3.1 "Protocol Design Implications", emphasizing resiliency, fault detection, and efficient routing convergence in overlay VPN designs like DMVPN.
NEW QUESTION # 392
A network engineering team is in the process of designing a lab network for a customer demonstration. The design engineer wants to show that the resiliency of the MPLS Traffic Engineering Fast Reroute solution has the same failover/failback times as a traditional SONET/SDH network (around 50 msec). In order to address both link failure and node failure within the lab topology network, which type of the MPLS TE tunnels must be considered for this demonstration?
Answer: D
Explanation:
To achieve sub-50ms protection against both link and node failures, MPLS TE Fast Reroute (FRR) with Next- Next-Hop (NNHop) protection is used:
* Next-Next-Hop tunnels provide node protection by pre-establishing a detour that bypasses not only the immediate next-hop link but also the entire next node.
* This ensures protection for both link and node failures, matching SONET/SDH resiliency targets.
Other options explained:
* A & C: TE backup and FRR backup tunnels may only provide link protection depending on deployment.
* B: Next-Hop tunnels address only link failures, not node failures.
NEW QUESTION # 393
