Question 2: An office has 8 floors with approximately 30-40 users per floor. What command must be configured on the router Switched Virtual Interface to use address space efficiently?

Answer:

• ip address 192.168.0.0 255.255.255.224

Question 3: A manager asks a network engineer to advise which cloud service models are used so employees do not have to waste their time installing, managing, and updating software which is only used occasionally. Which cloud service model does the engineer recommend?

Answer:

software-as-a-service Question 4: When a floating static route is configured, which action ensures that the backup route is used when the primary route falls?

Answer:

• The floating static route must have a higher administrative distance than the primary route so it is

used as a backup

Question 5: A router running EIGRP has learned the same route from two different paths. Which parameter does the router use to select the best path?

Answer:

metric

Question 6: What is the primary function of a Layer 3 device?

Answer:

to pass traffic between different networks

Question 7: What are two fundamentals of virtualization? (Choose two)

Answer:

• It allows logical network devices to move traffic between virtual machines and the rest of the physical

network

• It allows multiple operating systems and applications to run independently on one physical server

Question 8: What criteria is used first during the root port selection process?

Answer:

• lowest path cost to the root bridge

Question 9: A corporate office uses four floors in a building*

Floor 1 has 24 users* Floor 2 has 29 users* Floor 3 has 28 users* Floor 4 has 22 users Which subnet summarizes and gives the most efficient distribution of IP addresses for the router configuration?

Answer:

• 192.168.0.0/25 as summary and 192.168.0.0/27 for each floor

Question 10: Which keyword in a NAT configuration enables the use of one outside IP address for multiple inside hosts?

Answer:

overload

Question 11: How does the dynamically-learned MAC address feature function?

Answer:

• The CAM table is empty until ingress traffic arrives at each port

Question 12: Which three statements about MAC addresses are correct? (Choose three)

Answer:

• To communicate with other devices on a network, a network device must have a unique MAC

address

• A MAC address contains two main components, the first of which identifies the manufacturer of the

hardware and the second of which uniquely identifies the hardware

• An example of a MAC address is 0A:26:B8:D6:65:90

Question 13: What is a function of TFTP in network operations?

Answer:

transfers IOS images from a server to a router for firmware upgrades Question 14: An engineer must configure an OSPF neighbor relationship between router R1 and R3. The authentication configuration has been configured and the connecting interfaces are in the same 192.168.1.0/30 subnet. What are the next two steps to complete the configuration?(Choose two)

Answer:

• configure the interfaces as OSPF active on both sides

• configure both interfaces with the same area ID

Question 15: Which command is used to enable LLDP globally on a Cisco IOS ISR?

Answer:

lldp run

Question 16: Which statement about the nature of NAT overload is true?

Answer:

• applies a one-to-many relationship to internal IP addresses

Question 17: You have configured a router with an OSPF router ID, but its IP address still reflects the physical interface. Which action can you take to correct the problem in the least disruptive way?

Answer:

Reload the OSPF process Question 18: Router R1 must send all traffic without a matching routing-table entry to 192.168.1.1. Which configuration accomplishes this task?

• to determine the IP addresses of connected Cisco devices
• all of the above

Answer:

D Question 21: How do TCP and UDP differ in the way they provide reliability for delivery of packets?

Answer:

• TCP provides flow control to avoid overwhelming a receiver by sending too many packets at once,

UDP sends packets to the receiver in a continuous stream without checking for sequencing
