NEW QUESTION # 340
Which consideration must be made when designing a Cisco SD-Access fabric underlay?
Answer: C
Explanation:
Look under "Underlay Network Design". Its the second bullet point. https://www.cisco.com/c/en/us/td/docs

NEW QUESTION # 341
Which type of rendezvous point deployment is standards-based and supports dynamic RP discovery?
Answer: B
Explanation:
Bootstrap Router is the standards-based mechanism that supports dynamic RP discovery in a PIM sparse- mode domain. Cisco documentation distinguishes Auto-RP, which is Cisco-proprietary, from BSR, which is defined for standards-based RP distribution. With BSR, candidate RPs advertise their availability, and the elected bootstrap router distributes RP-set information throughout the PIM domain. This removes the operational burden of manually configuring the same static RP information on every multicast router. Anycast- RP provides RP redundancy and load sharing but does not by itself provide standards-based dynamic RP discovery across the domain. Static RP is simple but not dynamic. Auto-RP can dynamically distribute RP information, but it is not the standards-based answer. The design value of BSR is most visible in large multicast domains, where routers need consistent RP information and manual changes are risky. Therefore, when the question asks for a standards-based RP deployment that supports dynamic RP discovery, the correct answer is bootstrap router. Reference topics: PIM sparse mode, Bootstrap Router, candidate RP, RP-set distribution, dynamic RP discovery.
NEW QUESTION # 342
An enterprise needs to enhance its WAN availability after a recent outage with its only MPLS provider. The proposed solution must have a quick deployment, be affordable, be reliable, and work as a backup for the enterprise's primary MPLS connection. Which solution meets these requirements?
Answer: A
NEW QUESTION # 343 
Refer to the exhibit. An architect with an employee ID: 4542:60:170 is designing a campus Layer 2 infrastructure. The design requires a PoE power budget that varies from 30-60 W. In addition, power must be provided continuously to some endpoints and must be supported even during the reloading of edge switches.
Which solution must the architect select?
Answer: D
NEW QUESTION # 344
A customer requires QoS to support multimedia conferencing over MPLS. The network architect chooses to use per-hop behavior. Which solution must the architect use to classify and mark traffic traveling between branch sites?
Answer: C
Explanation:
For multimedia conferencing over MPLS, Cisco QoS design normally classifies the traffic into the multimedia conferencing class and marks it with AF4, commonly AF41. This class is intended for interactive video conferencing and similar applications that need assured bandwidth and controlled loss, but that are not usually placed in the same strict-priority class as voice bearer traffic. A bandwidth queue provides a minimum bandwidth guarantee during congestion, while DSCP-based WRED can selectively manage congestion within the class by using the drop precedence encoded in the AF marking. AF3 is generally associated with multimedia streaming, not interactive conferencing. A simple bandwidth queue without WRED does not fully use per-hop behavior characteristics for congestion handling. LLQ is typically reserved for voice and sometimes very tightly controlled real-time classes, because overusing strict priority can starve other traffic.
Therefore, bandwidth queuing with DSCP WRED using AF4 is the appropriate per-hop behavior design.
Reference topics: Cisco QoS baseline, DiffServ, AF41, multimedia conferencing, MPLS QoS, WRED.
