SRWE Final Exam Q's 61-120

61. Refer to the exhibit. A network administrator is reviewing the configuration of switch S1. Which protocol has been implemented to group multiple physical ports into one logical link?

• PAgP

• • DTP

• • LACP

• • STP

62. Which type of static route is configured with a greater administrative distance to provide a backup route to a route learned from a dynamic routing protocol?

• floating static route

• • default static route

• • summary static route

• • standard static route

63. What action takes place when a frame entering a switch has a unicast destination MAC address appearing in the MAC address table?

• • The switch updates the refresh timer for the entry.

• The switch forwards the frame out of the specified port.

• • The switch purges the entire MAC address table.

• • The switch replaces the old entry and uses the more current port.

64. The exhibit shows two PCs called PC A and PC B, two routes called R1 and R2, and two switches. PC A has the address 172.16.1.1/24 and is connected to a switch and into an interface on R1 that has the IP address 172.16.1.254. PC B has the address 172.16.2.1/24 and is connected to a switch that is connected to another interface on R1 with the IP address 172.16.2.254. The serial interface on R1 has the address 172.16.3.1 and is connected to the serial interface on R2 that has the address 172.16.3.2/24. R2 is connected to the internet cloud. Which command will create a static route on R2 in order to reach PC B?

• • R2(config)# ip route 172.16.2.1 255.255.255.0 172.16.3.1

• • R2(config)# ip route 172.16.2.0 255.255.255.0 172.16.2.254

• R2(config)# ip route 172.16.2.0 255.255.255.0 172.16.3.1

• • R2(config)# ip route 172.16.3.0 255.255.255.0 172.16.2.254

65. What protocol or technology allows data to transmit over redundant switch links?

• EtherChannel

• • DTP

• • STP

• • VTP

66. Refer to the exhibit. Which three hosts will receive ARP requests from host A, assuming that port Fa0/4 on both switches is configured to carry traffic for multiple VLANs? (Choose three.)

• • host B

• host C

• host D

• • host E

• host F

67. Refer to the exhibit. The network administrator configures both switches as displayed. However, host C is unable to ping host D and host E is unable to ping host F. What action should the administrator take to enable this communication?

• • Associate hosts A and B with VLAN 10 instead of VLAN 1.

• Configure either trunk port in the dynamic desirable mode.

• • Include a router in the topology.

• • Remove the native VLAN from the trunk.

• • Add the switchport nonegotiate command to the configuration of SW2.

68. What is the effect of entering the shutdown configuration command on a switch?

• • It enables BPDU guard on a specific port.

• It disables an unused port.

• • It enables portfast on a specific switch interface.

• • It disables DTP on a non-trunking interface.

69. What would be the primary reason an attacker would launch a MAC address overflow attack?

• • so that the switch stops forwarding traffic

• • so that legitimate hosts cannot obtain a MAC address

• so that the attacker can see frames that are destined for other hosts

• • so that the attacker can execute arbitrary code on the switch

70. During the AAA process, when will authorization be implemented?

• Immediately after successful authentication against an AAA data source

• • Immediately after AAA accounting and auditing receives detailed reports

• • Immediately after an AAA client sends authentication information to a centralized server

• • Immediately after the determination of which resources a user can access
