Q2. 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

Q4. A company uses site-to-site IPsec VPN tunnels established over the public internet as a backup to its private WAN. The interoffice IP telephony service quality is degraded when a failover event occurs. What known design limitation can cause this issue?
A. maximum headend router throughput
B. circuit bandwidth
C. transport reliability
D. number of remote sites
Answer: C
Q5. Refer to the exhibit. Based on the configuration, why are routers R1 and R2 not exchanging OSPF routes?
A. The OSPF process numbers are different.
B. There is no backbone area configured.
C. The router IDs are different.
D. OSPF is not enabled on the interfaces.
Answer: B
Q6. When designing the routing for an Enterprise Campus network it is important to keep which of the following route filtering aspects in mind?
A. Filtering is only useful when combined with route summarization
B. It is best to filter (allow) the default and summary prefixes only in the Enterprise Edge to remote sites or site-to-site IPsec VPN networks
C. IGPs (for example EIGRP or OSPF) are superior to route filtering in avoiding inappropriate transit traffic through remote nodes or inaccurate or inappropriate routing updates
D. The primary limitation of router filtering is that it can only be applied on outbound updates
Answer: B
Q7. Which technology fulfills these requirements?

B. Frame Relay
C. ATM
D. MPLS
E. X.25
Answer: C
Q8. There are 3 steps to confirm whether a range of IP addresses can be summarized. Which of the following is used in each of these 3 steps?
A. The first number in the contiguous block of addresses
B. The last number in the contiguous block of addresses
C. The size of the contiguous block of addresses
D. The subnet mask of the original network address
Answer: C
Q9. Which router type injects external LSAs into the OSPF database using either other routing protocols or static routes?
