  Correct Answer: A

• Question 192:

  A router has two static routes to the same destination network under the same OSPF process. How does the router forward packets to the destination if the next-hop devices are different?

  A. The router chooses the route with the oldest age.

  B. The router load-balances traffic over all routes to the destination.

  C. The router chooses the next hop with the lowest MAC address.

  D. The router chooses the next hop with the lowest IP address.

  Correct Answer: B

  Load balancing is a standard functionality of Cisco IOS Software that is available across all router platforms. It is inherent to the forwarding process in the router, and it enables a router to use multiple paths to a destination when it forwards packets. The number of paths used is limited by the number of entries that the routing protocol puts in the routing table. Four entries is the default in Cisco IOS Software for IP routing protocols except for BGP. BGP has a default of one entry.

• Question 193:

  Refer to the exhibit.

  

  How much OSPF be configured on the GigabitEthernet0/0 interface of the neighbor device to achieve the destined neighbor relationship?

  A. Router(config)#interface GigabitEthernet 0/0 Router(config-if)#ip ospf cost 5

  B. Router(config)#interface GigabitEthernet 0/0 Router(config-if)#ip ospf priority 1

  C. Router(config)#interface GigabitEthernet 0/0 Router(config-if)#ip ospf area 2

  D. Router(config)#interface GigabitEthernet 0/0 Router(config-if)#ip ospf network point-to-point

  Correct Answer: D

• Question 194:

  Which is a fact related to FTP?

  A. It uses block numbers to identify and mitigate data-transfer errors

  B. It always operates without user authentication

  C. It relies on the well-known UDP port 69.

  D. It uses two separate connections for control and data traffic

  Correct Answer: D

• Question 195:

  What is a purpose of traffic shaping?

  A. It enables dynamic flow identification.

  B. It enables policy-based routing.

  C. It provides best-effort service.

  D. It limits bandwidth usage.

  Correct Answer: D

  The purpose of traffic shaping is to limit the bandwidth usage of certain types of network traffic in order to prevent congestion and ensure that critical applications receive the necessary network resources.

  Traffic shaping is typically used to enforce Quality of Service (QoS) policies that prioritize certain types of network traffic, such as voice and video traffic, over other less critical traffic. By limiting the bandwidth usage of non-critical traffic, traffic shaping can help prevent network congestion and ensure that the available bandwidth is allocated in a way that meets the organization's priorities.

• Question 196:

  What is the role of nonoverlapping channels in a wireless environment?

  A. to reduce interference

  B. to allow for channel bonding

  C. to stabilize the RF environment

  D. to increase bandwidth

  Correct Answer: A

  The role of nonoverlapping channels in a wireless environment is to reduce interference between wireless devices. In wireless networks, such as Wi-Fi networks, different devices transmit data wirelessly using specific frequency bands. These frequency bands are divided into channels, which act as virtual pathways for data transmission.

  When multiple wireless devices operate in close proximity and use overlapping channels, there is a potential for interference. Interference occurs when devices in overlapping channels transmit signals simultaneously, leading to signal degradation and reduced performance.

  Nonoverlapping channels are spaced far enough apart to minimize interference between adjacent channels. By assigning wireless devices to nonoverlapping channels, network administrators can reduce interference and improve overall network performance. This allows devices operating on different channels to transmit data without significantly overlapping with adjacent channels.

  Therefore, the primary role of nonoverlapping channels in a wireless environment is to reduce interference, enhancing the stability and reliability of wireless communication.

• Question 197:

  How do TCP and UDP fit into a query-response model?

  A. TCP establishes a connection prior to sending data, and UDP sends immediately.

  B. TCP uses error detection for packets, and UDP uses error recovery.

  C. TCP avoids using sequencing, and UDP avoids using acknowledgments.

  D. TCP encourages out-of-order packet delivery, and UDP prevents re-ordering.

  Correct Answer: A

• Question 198:

  Refer to the exhibit.

  

  An engineer executed the script and added commands that were not necessary for SSH and now must remove the commands.

  A. metric

  B. cost

  C. longest prefix

  D. administrative distance

  Correct Answer: D

• Question 199:
