Demo Questions

Question 1
Which effect of using ingress filtering to prevent spoofed addresses on a network design is true?
  1. It reduces the effectiveness of DDoS attacks when associated with DSCP remarking to Scavenger.
  2. It protects the network Infrastructure against spoofed DDoS attacks.
  3. It Classifies bogon traffic and remarks it with DSCP bulk.
  4. It filters RFC 1918 IP addresses.
Correct answer: B
Question 2
Which BGP feature provides fast convergence?
  1. BGP PIC
  2. BGP-EVPN
  3. BGP FlowSpec
  4. BGP-LS
Correct answer: A
Question 3
Company XYZ asks for design recommendations for Layer 2 redundancy. The company wants to prioritize fast convergence and resiliency elements in the design.
Which two technologies are recommended? (Choose two.)
  1. Design MLAG/MC-LAG into the network wherever possible.
  2. Configure DHCP snooping on the switches.
  3. Use root guard.
  4. Use BPDU guard.
  5. Use UniDirectional Link Detection.
Correct answer: AE
Question 4
Which two features control multicast traffic in a VLAN environment? (Choose two)
  1. IGMP snooping
  2. MLD snooping
  3. RGMP
  4. PIM snooping
  5. pruning
Correct answer: AB
Question 5
Which encoding format does cisco ios XE software support for NETCONF?
  1. It supports HTML encoding for NETCONF
  2. It supports YAML encoding for NETCONF
  3. It supports XML encoding for NETCONF
  4. It supports JSON encoding for NETCONF
Correct answer: C
Question 6
Drag and drop the design use cases from the left onto the correct uRPF techniques used to prevent spoofing attacks.
Not all options are used.
Correct answer: To work with this question, an Exam Simulator is required.
Explanation:
  
  
Question 7
Company XYZ runs OSPF in their network. A design engineer decides to implement hot-potato routing architecture.
How can this implementation be achieved?
  1. Enable iBGP and apply prepend to ensure all prefixes will have the same length of the AS pathattribute value.
  2. Redistribute the external prefixes onto OSPF and ensure the total metric calculation includes onlythe ext value and the value is the same in all ASBRs.
  3. Enable OSPF load-balancing over unequal cost path.
  4. Redistribute the external prefixes onto OSPF and ensure that the total metric calculation includesexternal internal values.
Correct answer: D
Question 8
Which MPLS TE design consideration is true?
  1. MPLS TE replaces LDP and the dependency of the IGP to identify the best path.
  2. MPLS TE provides link and node protection
  3. MPLS TE optimizes the routing of IP traffic, given the constraints imposed by backbone capacityand application requirements.
  4. MPLS TE requires Layer 3 VPN full-mesh topology deployment
Correct answer: C
Question 9
Which network management framework can be used to develop a network architecture that contains business requirements analysis, gap analysis, and network diagrams as artifacts to be used for design and implementation later?
  1. TOG
  2. ITIL
  3. FCAPS
  4. Cobit
Correct answer: C
Question 10
Refer to the exhibit.
     
The enterprise customer wants to stream one-way video from their head office to eight branch offices using multicast. Their current service provider provides a Layer3 VPN solution and manages the CE routers, but they do not currently support multicast. Which solution quickly allows this multicast traffic to go through while allowing for future scalability?
  1. Enable a GRE tunnel between nodes CE1 and CE2
  2. Enable a GRE tunnel between nodes C2 and C4
  3. Enable a GRE tunnel between nodes C1 and C4
  4. Implement hub and spoke MPLS VPN over DMVPN (also known as 2547o DMVPN) between CE1and CE2
  5. The service provider must provide a Draft Rosen solution to enable a GRE tunnel between nodesPE1 and PE2
