Title : Troubleshooting and Maintaining Cisco IP Networks

1. EIGRP is being used as the routing protocol on the Cisco network. While troubleshooting some network connectivity issues, you notice a large number of EIGRP SIA (Stuck in Active) messages. What causes these SIA routes? (Select two)
A. The neighboring router stops receiving ACK packets from this router.
B. The neighboring router starts receiving route updates from this router.
C. The neighboring router is too busy to answer the query (generally caused by high CPU utilization).
D. The neighboring router is having memory problems and cannot allocate the memory to process the query or build the reply packet.
Answer: CD

2. Part of the routing table of router Cisco1 is displayed below:
From analyzing the above command output, what is the administrative distance of the external EIGRP routes?
A. 24
B. 32
C. 90
D. 170
E. 27316
F. None of the other alternatives apply
Answer: D

3. In computer networking a multicast address is an identifier for a group of hosts that have joined a multicast group. Multicast addressing can be used in the Link Layer (OSI Layer 2), such as Ethernet Multicast, as well as at the Internet Layer (OSI Layer 3) as IPv4 or IPv6 Multicast. Which two descriptions are correct regarding multicast addressing?
A. The first 23 bits of the multicast MAC address are 0x01-00-5
E. This is a reserved value that indicates a multicast application.
B. The last 3 bytes (24 bits) of the multicast MAC address are 0x01-00-5
E. This is a reserved value that indicates a multicast application.
C. To calculate the Layer 2 multicast address, the host maps the last 23 bits of the IP address into the last 24 bits of the MAC address. The high-order bit is set to 0.
D. The first 3 bytes (24 bits) of the multicast MAC address are 0x01-00-5
E. This is a reserved value that indicates a multicast application.
Answer: CD

4. At which layer of the OSI model does the Spanning Tree Protocol (STP) operate at?
A. Layer 5
B. Layer 4
C. Layer 3
D. Layer 2
E. Layer 1
Answer: D

5. Which two statements about the Cisco Aironet Desktop Utility (ADU) are true? (Select two)
A. The Aironet Desktop Utility (ADU) profile manager feature can create and manage only one profile for the wireless client adapter.
B. The Aironet Desktop Utility (ADU) can support only one wireless client adapter installed and used at a time.
C. The Aironet Desktop Utility (ADU) can be used to establish the association between the client adapter and the access point, manage authentication to the wireless network, and enable encryption.
D. The Aironet Desktop Utility (ADU) and the Microsoft Wireless Configuration Manager can be used at the same time to configure the wireless client adapter.
Answer: BC
