Refer to the exhibit. What is the metric of the route to the 192.168.10.33/28 subnet?
Show answer
Answer: D
Explanation
he metric of the route to the 192.168.10.32/28 subnet is 110, not 193. The metric is the administrative distance, which is a value that indicates the preference of a route. The lower the metric, the more preferred the route is. In this case, the metric of 110 is the sum of the administrative distance of the serial interface (84) and the cost of the path to the next hop (26). The administrative distance of a serial interface is typically 84, while the cost of the path to the next hop is typically the number of hops to the next hop. In this case, the next hop is 192.168.30.10, which is one hop away. Therefore, the metric of the route to the 192.168.10.32/28 subnet is 110. "this is because the output is using a Cisco IOS-style format" **Cisco IOS-style format:** [metric]/[administrative distance] [destination network] [via next hop] **Other styles:** [administrative distance]/[metric] [destination network] [via next hop]

Question 876 · 1334 in bank
What prevents a workstation from receiving a DHCP address?
Show answer
Answer: A
Explanation
I think its STP, specifically portfast. I found this one the cisco white pages, under the DHCP troubleshooting section. "...verify that the port has STP portfast enabled and trunking/channeling disabled. The default configuration is STP portfast disabled and trunking/channeling auto, if applicable. For the 2900XL/3500XL/2950/3550 switches, STP portfast is the only required configuration. These configuration changes resolve the most common DHCP client issues that occur with an initial installation of a Catalyst switch." from https://www.cisco.com/c/en/us/support/docs/ip/dynamic-address-allocation-resolution/27470-100.html#anc72

Question 878 · 1334 in bank
Which QoS forwarding per-hop behavior changes a specific value in a packet header to set the class of service for the packet?
Show answer
Answer: D
Explanation
Answer is correct: Chatgpt: Marking is a QoS technique where a value is modified or added to a specific field in the packet header to indicate the class or priority of the packet. This marking can be used to differentiate and prioritize different types of traffic based on their specific requirements. For example, in IP-based networks, the Differentiated Services Code Point (DSCP) field in the IP header can be modified to set the class of service for a packet. By changing the value of the DSCP field, the packet is marked with a specific priority or class, allowing routers and switches along the network path to apply appropriate QoS policies and forwarding behaviors. Marking is crucial in QoS implementation as it enables network devices to identify and treat packets differently based on their class of service, ensuring that higher-priority traffic, such as voice or real-time applications, receives preferential treatment and appropriate QoS handling.
