Q81. Refer to the exhibit. Which option should be the default gateway for the PC1 that is shown?
Q82. Recently, the WAN links between the headquarters and branch offices have been slow under peak congestion, yet multiple alternate WAN paths exist that are not always congested. What technology can allow traffic to be routed in a more informed manner to utilize transport characteristics such as delay, loss, or link load?
A. performance routing
B. static routing
C. on demand routing
D. policy based routing
Q83. Refer to the exhibit. A customer requires a web application implementation, but the web server has communication only to the application server and users, and the database server has communication only to the application server. What firewall design is the best fit for this scenario?
A. transparent mode with the servers on the same subnet
B. routed mode with three security zones
C. transparent mode with three security zones
D. routed mode with two security zones
Q84. Which type of application traffic typically requires prioritization across networks and may use a DSCP value of 34 (AF41)?
B. interactive video
C. call signaling
E. streaming video
F. network management
Q85. 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
Q86. Which algorithm does IS-IS use to determine the shortest path through a network?
A. Bellman-Ford routing algorithm
C. Dijkstra's algorithm
D. Floyd-Warshall algorithm
Q87. Which two WAN technologies support IEEE 802.1Q, site-to-site connectivity, and point-to-point connectivity between two offices? (Choose two.)
A. Ethernet over MPLS
C. Layer 3 MPLS
Q88. What SAN technology can accomplish fabric infrastructure implementation using multiple fabrics?
Q89. An HSRP design requirement states that preemption must be enabled for the active switch, which is a Cisco 4507R. Assume a boot time of 300 seconds. Which setting of the preemption delay timer minimizes the loss of traffic?
A. 50 seconds
B. 100 seconds
C. 150 seconds
D. 200 seconds
Q90. 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
