Q25. You need to redesign your NMS system so that it can collect information without causing adverse effects in the network, such as high CPU utilization on network devices and network instability. Which two options will minimize the impact of the trusted NMS polling your network in this situation? (Choose two.) 

A. Implement SNMP community restrictions that are associated with an ACL. 

B. Unload unused MIBs from the network devices. 

C. Prevent polling of large tables through the use of SNMP OID restrictions. 

D. Disable unused OIDs and MIBs on the NMS systems. 

Answer: CD 


Q26. A switched network is being designed to support a manufacturing factory. Due to cost constraints, fiber-based connectivity is not an option. Which design allows for a stable network when there is a risk of interference from the manufacturing hardware in use on the factory floor? 

A. Design the network to include UDLD to detect unidirectional links and take them out of service. 

B. Design the network to include EtherChannel bundles to prevent a single-link failure from taking down a switch interconnection point. 

C. Design the network to include loop guard to prevent a loop in the switched network when a link has too much interference. 

D. Design the network to include BackboneFast on all devices to accelerate failure convergence times. 

Answer: A 


Q27. You are the lead IP/MPLS network designer of a service provider called XYZ. You are leading a design discussion regarding IPv6 implementation in the XYZ MPLS network, using MPLS 6PE/6VPE techniques. Currently, XYZ provides IPv4 multicast services over an MPLS network by using MVPN, and would like to provide parallel IPv6 multicast services. Which three multicast solutions should be enabled? (Choose three.) 

A. native IPv6, only for multicast services 

B. MPLS 6PE/6VPE, because it provides IPv6 multicast support by default 

C. an overlay model using Layer 2 MPLS tunnels 

D. PIM-DM to enable IPv6 multicast in conjunction with MPLS 6PE/6VPE 

E. MVPN for IPv6 multicast service 

Answer: ACE 


Q28. You are designing a Group Encrypted Transport virtual private network solution for an existing branch network. The existing network has the following characteristics: 

. 50 remote sites (with an additional 30 remote sites expected over the next 3 years) . Connectivity between all sites is via Multiprotocol Label Switching Layer 3 virtual private network service from a single provider . Open Shortest Path First is the routing protocol used between provider edge and customer edge routers . The customer edge routers will become group members performing the encryption between sites 

Which additional routing protocol would you use for the overlay routing between the group members? 

A. Open Shortest Path First (with a different process ID) 

B. Enhanced Interior Gateway Routing Protocol 

C. No additional protocol is necessary. 

D. External Border Gateway Protocol 

E. Routing Information Protocol Version 2 

F. Next Hop Resolution Protocol 

Answer: C 


Q29. You are identifying performance management requirements for a VoIP migration. What three key performance indicators would you use to track media quality? (Choose three.) 

A. delay 

B. trunk group usage 

C. jitter 

D. packet loss 

E. call processing (call detail records) 

F. call processing (performance counters) 

G. echo 

H. crosstalk 

Answer: ACD 


Q30. What should be taken into consideration when designing IPsec networks using Authentication Header (AH)? 

A. NAT 

B. transform set 

C. crypto maps 

D. ISAKMP 

Answer: A 


Q31. ACME Corporation is integrating IPv6 into their network, which relies heavily on multicast distribution of data. Which two IPv6 integration technologies support IPv6 multicast? (Choose two.) 

A. 6VPE 

B. 6PE 

C. dual stack 

D. ISATAP 

E. 6to4 

F. IPv6INIP 

Answer: CF 


Q32. Refer to the exhibit. 

This Layer 2 ring has 10 VLANs with 1000 MAC addresses in each VLAN. Which protocol or mechanism provides the shortest traffic outage if the link marked with "X" fails? 

A. PVRST 

B. REP 

C. MST 

D. G.8031 

E. BFD 

Answer: B
