1A company plans to include Nonstop Forwarding and Bidirectional Forwarding Detection as a part of their network redundancy plan. In which two ways do NSF and BFD work together when different hardware platforms are compared? (Choose two.)
- During supervisor engine or routing engine failover, the NSF feature will always ensure that the BFD at the peer router will not trigger a link down independent of the used hardware platform.
- At some hardware platforms, BFD and NSF are not supported together. During supervisor engine or routing engine failover, the BFD at the peer router will trigger a link down.
- To ensure that BFD at the peer router will not trigger a link down during NSF, the BFD packets must be processed fast enough, and, during supervisor engine or routing engine failover, by processing the BFD independent from the supervisor engine or routing engine.
- Because BFD is always processed at the line cards (not at the supervisor engine or routing engine), a supervisor engine or routing engine failover will not affect the BFD peer router.
- Because BFD is always processed at the supervisor engine or routing engine, a supervisor engine or routing engine failover will always trigger a link down at the peer router.
Answer:
2While reviewing an existing network design, you are discussing the characteristics of different STP versions. Which protocol minimizes unicast flooding during
TCN in a Layer 2 switched network with many VLANs?
- STP
- MST
- PVRSTP
- PVSTP+
Answer: D
3When designing a WAN that will be carrying real-time traffic, what are two important reasons to consider serialization delay? (Choose two.)
- Serialization delays are variable because they depend on the line rate of the interface and on the type of the packet being serialized.
- Serialization delay depends not only on the line rate of the interface but also on the size of the packet.
- Serialization delays are invariable because they depend only on the line rate of the interface.
- Serialization delays are variable because they depend only on the size of the packet being serialized.
- Serialization delay is the time required to transmit the packet on the physical media.
Answer:
4Among the design criteria for a network is the requirement that bandwidth capacity be managed proactively. Which two techniques would most effectively support the proactive management of network bandwidth capacity? (Choose two.)
- analyze network bandwidth utilization to establish a baseline
- implement QoS to increase available bandwidth and overall throughput
- implement utilization measurement and tracking measures in the network
- configure SNMP MIB collectors to trigger at utilization thresholds
Answer:
5What are the two preferred mechanisms for detecting Layer 2 link failures quickly? (Choose two.)
- BFD
- fast RSVP hellos
- LDP keepalives
- loss of signal
Answer:
6Which IPv4 addressing and routing scheme can increase the availability of a network service during a DoS attack?
- unicast
- broadcast
- anycast
- multicast
Answer: C
7What are two benefits of protecting the control plane of a network device? (Choose two.)
- prevents the delivery of packets from spoof sources
- preserves the confidentiality of traffic encrypted by IPsec
- maintains routing protocol adjacencies with local neighbors 46
- maintains remote management access to the router
Answer:
8Refer to the exhibit. On R2 there is a summary route for 192.168.1.0/24 with a next hop of R4. Which change will cause R2 to prefer a path through R1 to reach
192.168.1.0/24?
- convert Area 1 to a stub area and decrease the cost between R1 and R3 to 1
- create a virtual link between R1 and R2
- create a virtual link between R1 and R2 and decrease the cost between R1 and R3 to 1
- change the link between R1 and R2 to Area 0
Answer: C
9Which two OSPF design considerations should you implement to support the eventual growth of a network, so that CPU and memory are unaffected by the size and complexity of the link-state database in a large service provider network? (Choose two.)
- Turn on route dampening.
- Create network summaries.
- Turn on the Incremental SPF feature.
- Add more memory.
- Turn on packet pacing.
- Add redundancy between critical locations.
Answer:
10Your 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.)
- Flexible Netflow
- Remote Monitoring
- Cisco IOS IP Service Level Agreement
- Class-Based Quality of Service Management Information Base
- Network-Based Application Recognition
