When constraint-based routing is under consideration to be added to a network design, what are two inherent characteristics or impacts that must be considered? (Choose two)
- A . better network utilization
- B . stability in the route table
- C . high computation overhead
- D . smaller routing table size
- E . less resources than the shortest path
Agile and Waterfall are two popular methods for organizing projects.
What describes any Agile network design development process?
- A . working design over comprehensive documentation
- B . contract negotiation over customer collaboration
- C . following a plan over responding to change
- D . processes and tools over individuals and interactions over time
You have been asked to design a high-density wireless network for a university campus.
Which two principles would you apply in order to maximize the wireless network capacity? (Choose two.)
- A . Implement a four-channel design on 2.4 GHz to increase the number of available channels
- B . Choose a high minimum data rate to reduce the duty cycle.
- C . increases the number of SSlDs to load-balance the client traffic.
- D . Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual-band clients are used.
- E . Enable 802.11n channel bonding on both 2.4 GHz and 5 GHz to increase the maximum aggregated cell throughput.
Company ABC uses IPv4-only. Recently they started deploying new endpoint devices. For operational reasons, IPv6 cannot be disabled on these new endpoint devices.
Which security measure prevents the new endpoint from learning an IPv6 prefix from an attacker?
- A . Source Guard and Prefix Guard
- B . Router Advertisement Guard
- C . Prefix Guard
- D . Secure Neighbor Discovery
Refer to the exhibit.
A service provider has a requirement to use Ethernet OAM to detect end-to-end connectivity failures between SP-SW1 and SP- SW2.
Which two ways to design this solution are true? (Choose two)
- A . Enable unicast heartbeat messages to be periodically exchanged between MEPs
- B . Enable Connectivity Fault Management on the SP switches
- C . Use upward maintenance endpoints on the SP switches
- D . Forward E-LMI PDUs over VPLS
- E . Forward LLD PDUs over the VPLS
A business requirement is supplied to an architect from a car manufacturer stating their business model is changing to just-in-time manufacturing and a new network is required, the manufacturer does not produce all of the specific components m-house.

A customer network design team is planning a migration from a legacy TDM-based L2VPN to an MPLS-based L3VPN Migration is planned in a phased approach:
• OSPF backbone Link between HUB A and HUB B sites to be migrated to eBGP
• Spoke A2 and Spoke B1 will be migrated to the L3VPN
Which solution design can be considered to avoid routing loops during backbone link migration?
- A . Enable route-filtering on OSPF backbone routers for spoke traffic
- B . Advertise low AD value for transit traffic on hub sites.
- C . OSPF backbone area advertises summarized routes to hub.
- D . Redistribute EIGRP 200 and 300 with low cost into BGP
Company XYZ, a global content provider, owns data centers on different continents. Their data center design involves a standard three-layer design with a Layer 3-only core. HSRP is used as the FHRP. They require VLAN extension across access switches in all data centers, and they plan to purchase a Layer 2 interconnection between two of their data centers in Europe.
In the absence of other business or technical constraints, which termination point is optimal for the Layer 2 interconnection?
- A . at the core layer, to otter the possibility to isolate STP domains
- B . at me aggregation layer because it is the Layer 2 to Layer 3 demarcation point
- C . at the access layer because the STP root bridge does not need to align with the HSRP active node.
- D . at the core layer because all external connections must terminate there for security reasons
