Q91. Network designers plan to interconnect two geographically separated data centers using an Ethernet-over-MPLS pseudowire. Within that design, the link between the sites is stable, there are no apparent loops in the topology, and the root bridges for the respective VLANs are stable and unchanging. What additional aspect of the design should be adjusted to mitigate the chance of connectivity issues to the peer data center when the connection takes place?
A. Enable 802.1d on one data center, and 802.1w on the other.
B. Ensure that the spanning tree diameter for one or more VLANs is not too large.
C. Enable UDLD on the link between the data centers.
D. Enable root guard on the link between the data centers.
Q92. Your company needs to baseline web traffic on a per-session basis for network application reporting. Which two mechanisms, when combined, fulfill the requirement? (Choose two.)
A. Flexible Netflow
B. Remote Monitoring
C. Cisco IOS IP Service Level Agreement
D. Class-Based Quality of Service Management Information Base
E. Network-Based Application Recognition
Q93. What are two benefits of using BFD for failure detection in the design of a network?
A. BFD can provide failure detection in less than one second.
B. BFD can be used as a generic and consistent failure detection mechanism for EIGRP, IS-IS, and OSPF.
C. BFD eliminates router protocol hello notification.
D. BFD can be used for all types of network interfaces.
E. BFD is independent of the network protocol.
Q94. You are designing a wireless LAN with the following components:
High-density indoor access point deployment
2.4-GHz and 5-GHz radios
802.11a, 802.11g, and 802.11n mode wireless LAN clients
Site survey results show negligible foreign WiFi and non-WiFi interference. What is the best method to decrease duty cycle (radio frequency utilization) and increase overall wireless LAN client performance for this design?
A. Disable all data rates below 12 Mb/s on all access points.
B. Decrease radio transmit power on all access points that report a high duty cycle.
C. Increase radio transmit power on all access points that report a high duty cycle.
D. Disable all data rates above 12 Mb/s on all access points.
E. Increase radio transmit power on all access points.

Q96. Refer to the exhibit.
Service Provider A and Service Provider B have agreed to a strategic interconnect relationship that will allow them access into each other's geographies by using an inter-AS eBGP VPNv4 multihop between route reflectors. Which two options will accomplish this scenario? (Choose two.)
A. RR 1 and RR 2 peer using multihop eBGP VPNv4 to exchange prefixes.
B. ASBR 1 and ASBR 2 act as inline route reflectors that set themselves as the next-hop.
C. An LSP is formed between ASBR 1 and ASBR 2 using eBGP IPv4.
