10 Tips For Avant-garde 352-001 practice test

Q1. Refer to the exhibit. 

A service provider would like to use Ethernet OAM to detect end-to-end connectivity failures between SP-SW1 and SP-SW2. In which two of these ways can you design this solution? (Choose two.) 

A. Enable Y.1731 Connectivity Fault Management on the SP switches. 

B. E-LMI PDUs must be forwarded over VPLS. 

C. Cisco Discovery Protocol PDUs must be forwarded over the VPLS. 

D. Use upward maintenance endpoints on the SP switches. 

E. Enable IEEE 802.1ag Connectivity Fault Management on the SP switches.

Q2. Your design plan includes mutual redistribution of two OSPF networks at multiple locations, with connectivity to all locations in both networks. How is this accomplished without creating routing loops? 

A. Use route maps on the ASBRs to allow only internal routes to be redistributed. 

B. Use route maps on the ASBRs to allow internal and external routes to be redistributed. 

C. Use route maps on the ASBRs to set tags for redistributed routes. 

D. Use route maps on the ASBRs to filter routes with tags so they are not redistributed.

A. Use a WRED random drop policy. 

B. Increase the queue to at least 1 GB. 

C. Enable the TCP Nagle algorithm on the receiver. 

D. Change the protocol to CIFS.

Q7. A data center provider has designed a network using these requirements: 

Two data center sites are connected to the public Internet. 

Both data centers are connected to different Internet providers. 

Both data centers are also directly connected with a private connection for the internal traffic, and public Internet traffic can also be routed at this direct connection. 

The data center provider has only one /19 public IP address block. 

Under normal conditions, Internet traffic should be routed directly to the data center where the services are located. When one Internet connection fails, the complete traffic for both data centers should be routed by using the remaining Internet connection. In which two ways can this routing be achieved? (Choose two.) 

A. The data center provider must have an additional public IP address block for this routing. 

B. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out with a low BGP weight and the /20 block from the remote data center is sent out with a higher BGP weight at both sites. 

C. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out without path prepending and the /20 block from the remote data center is sent out with path prepending at both sites. 

D. One /20 block is used for the first data center and the second /20 block is used for the second data center. Each /20 block is only sent out locally. The /19 block is sent out at both Internet connections for the backup case to reroute the traffic through the remaining Internet connection. 

E. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out with a low BGP local preference and the /20 block from the remote data center is sent out with a higher BGP local preference at both sites. 

F. BGP will always load-balance the traffic to both data center sites.

Q8. A Tier-3 Service Provider is evolving into a Tier-2 Service Provider due to the amount of Enterprise business it is receiving. The network engineers are re-evaluating their IP/MPLS design considerations in order to support duplicate/overlapping IP addressing from their Enterprise customers within each Layer 3 VPN. Which of the following would need to be reviewed to ensure stability in their network? 

A. Assigning unique Route Target ID's 

B. Assigning unique Route Distinguishers 

C. Assigning unique IP address space for the Enterprise NAT/Firewalls 

D. Assigning unique VRF ID's to each Layer 3 VPN

Q9. Which three reasons to deploy an IDS sensor in promiscuous mode when you design a security solution are true? (Choose three.) 

A. Solution should be resistant to sensor failure. 

B. Solution should allow for stream normalization. 

C. Solution should not impact jitter and latency for voice traffic. 

D. Solution should allow for signature-based pattern matching. 

E. Solution should allow to deny packets inline.

Q10. Which technique can you use to detect forwarding path failures at a uniform rate, and reconvergence times will be consistent and predictable when your routers are in the same broadcast domain? 

A. Enable BFD on your routers. 

B. Configure your routers with IP-SLA to ping the peer router. 

C. Configure your routers with IP-SLA and track to ping the peer and switch to a default route if the pings fail. 

D. Tune your routing protocol timers.
