An architect designs a multi-controller network architecture with these requirements:
- Achieve fast failover to control traffic when controllers fail.
- Yield a short distance and high resiliency in the connection between the switches and the controller.
- Reduce connectivity loss and enable smart recovery to improve the SDN survivability.
- Improve connectivity by adding path diversity and capacity awareness for controllers.
Which control plane component of the multi-controller must be built to meet the requirements?

• C. control path reliability
• D. controller clustering

Answer: B

NEW QUESTION 4
Retef to the exhibit. This network is running OSPF and EIGRP as the routing protocols. Mutual redistribution of the routing protocols has been contoured on the appropriate ASBRs. The OSPF network must be designed so that flapping routes in EIGRP domains do not affect the SPF runs within OSPF. The design solution must not affect the way EIGRP routes are propagated into the EIGRP domains.
Which technique accomplishes the requirement?

• A. route summarization the ASBR interfaces facing the OSPF domain
• B. route summarization on the appropriate ASBRS.
• C. route summarization on the appropriate ABRS.
• D. route summarization on EIDRP routers connecting toward the ASBR

Answer: B

NEW QUESTION 5

• A. MAC tunneling
• B. IS-IS multipath
• C. RPF check
• D. TTL header

Answer: CD

NEW QUESTION 6
A Service Provider is designing a solution for a managed CE service to a number of local customers using a single CE platform and wants to have logical separation on the CE platform using Virtual Routing and Forwarding (VRF) based on IP address ranges or packet length.

• A. Static Routes for Route Leaking
• B. Policy Based Routing
• C. OSPF per VRF Instance
• D. Multi-Protocol BGP

Answer: B

NEW QUESTION 7
A senior network designer suggests that you should improve network convergence times by reducing BGP timers between your CE router and the PE router of the service provider.
Which two factors should you consider to adjust the timer values? (Choose two.)

• A. service provider agreement to support tuned timers
• B. manual updates to the peer groups
• C. service provider scheduling of changes to the PE
• D. number of routes on the CE router
• E. number of VRFs on the PE router

Answer: AD

NEW QUESTION 10
Company XYZ is in the process of identifying which transport mechanism(s) to use as their WAN technology.
Their main two requirements are.
- a technology that could offer DPI, SLA, secure tunnels, privacy, QoS, scalability, reliability, and ease of management
- a technology that is cost-effective
Which WAN technology(ies) should be included in the design of company XYZ?

• A. Software-defined WAN should be the preferred choice because it complements both technologies, covers all the required features, and it is the most cost-effective solution.
• B. Internet should be the preferred option because it is cost effective and supports BFD, IP SL
• C. andIPsec for secure transport over the public Internet.
• D. Both technologies should be use
• E. Each should be used to back up the other one; where theprimary links are MPLS, the internet should be used as a backup link with IPsec (and vice versa).
• F. MPLS meets all these requirements and it is more reliable than using the Interne
• G. It is widelyused with defined best practices and an industry standard.

Answer: A

NEW QUESTION 11
Company XYZ is designing the network for IPv6 security and they have these design
requirements:
- A switch or router must deny access to traffic from sources with addresses that are correct, but
are topologically incorrect
- Devices must block Neighbor Discovery Protocol resolution for destination addresses that are
not found in the binding table.
Which two IPv4 security features are recommended for this company? (Choose two)

• A. IPv6 DHCP Guard
• B. IPv6 Source Guard
• C. IPv6 Destination Guard
• D. IPv6 Prefix Guard
• E. IPv6 RA Guard

Answer: CD

NEW QUESTION 12
Company XYZ is running OSPF in their network. They have merged with another company that is running EIGRP as the routing protocol. Company XYZ now needs the two domains to talk to each other with redundancy, while maintaining a loop free environment.
The solution must scale when new networks are added into the network in the near future.
Which technology can be used to meet these requirements?

• A. multipoint route-redistribution with route filtering using ACLs
• B. DUMP multipoint route-redistribution with route filtering using route tags
• C. DUMPS single point route-redistribution with route filtering using route tags
• D. DUMPS single point route-redistribution with route filtering using ACLs
