Q121. Which router type injects external LSAs into the OSPF database using either other routing protocols or static routes?
A. backbone router
C. internal router
D. designated router
Q122. Which practice is recommended when designing scalable OSPF networks?
A. Maximize the number of routers in an area.
B. Minimize the number of ABRs.
C. Minimize the number of areas supported by an ABR.
D. Maximize the number of router adjacencies.
Q123. Which three options are features of IP SLAs? (Choose three.)
A. enables verification of service guarantees
B. dynamically adjusts QoS parameters
C. validates network performance and metrics
D. initiates failover for saturated links
E. proactively identifies network related issues
Q124. Which IPv6 transition model should be utilized when two or more independent transition mechanisms are required?
B. dual stack
C. service block
Q125. In a collapsed core design, which three benefits are provided by a second-generation Cisco MDS director? (Choose three.)
A. a higher fan-out ratio
B. fully redundant switches
C. 100 percent port efficiency
D. all ISLs contained within a single chassis
E. higher latency and throughput than a core-edge design switch
Q126. An organization is deploying a new load balancing environment to support sensitive applications. The security requirements include discrete IP segments used for VIPs and for the application hosts. What load balancer mode meets the requirements?
Q127. What is the next action taken by the Cisco NAC Appliance after it identifies a vulnerability on a client device?
A. denies the client network resource access
B. repairs the effected devices
C. generates a Syslog message
D. permits the client but limits to guest access
Q128. Which Cisco NAC Appliance component is optional?
A. NAC Appliance Manager
B. NAC Appliance Server
C. NAC Appliance Agent
D. NAC Appliance Policy Updates
Q129. Which of the following two statements about Cisco NSF and SSO are the most relevant to the network designer? (Choose two.)
A. You can reduce outages to 1 to 3 seconds by using SSO in a Layer 2 environment or Cisco NSF with SSO in a Layer 3 environment.
B. SSO and NSF each require the devices to either be graceful restart-capable or graceful restart-aware.
C. In a fully redundant topology adding redundant supervisors with NSF and SSO may cause longer convergence times than single supervisors with tuned IGP timers
D. The primary deployment scenario for Cisco NSF with SSO is in the Distribution and Core layers.
E. Cisco NSF-aware neighbor relationships are independent of any tuned IGP timers
Q130. Which option prevents the dropping of asymmetrically routed packets in active/active failover paired firewalls?
A. Nothing can be done to prevent this from happening.
B. Configure different policies on both firewalls.
C. Assign similar interfaces on each firewall to the same asymmetric routing group.
D. Assign similar interfaces on each firewall to a different asymmetric routing group.
