質問 # 13
At which prompt can the ping command be executed?

• A. ICX7150-C12 Router(config)#
• B. ICX7150-C12 Router(config-if-mgmt-1)#
• C. ICX7150-C12 Router#
• D. ICX7150-C12 Router(config-if-e1000-1/1/1)#

正解：C

解説：
* Understanding CLI Levels:
* The ping command is used to test connectivity to other devices by sending ICMP echo requests.
* It can only be executed from the privileged EXEC mode, which is indicated by the Router# prompt.
* Why Other Prompts Don't Work:
* A. Router(config-if-mgmt-1)#: This is the interface configuration mode for the management port and does not allow execution of diagnostic commands like ping.
* B. Router(config)#: This is the global configuration mode, which is used to configure the switch but does not support diagnostic commands.
* D. Router(config-if-e1000-1/1/1)#: This is the interface configuration mode for Ethernet 1/1/1, which also does not allow execution of ping.

質問 # 23
Which three objects can be assigned a Layer 3 address? (Choose three.)

• A. Virtual LAN
• B. Loopback
• C. VxLAN
• D. GRE tunnels
• E. Stack Interface
• F. Virtual Ethernet

正解：B、D、E

解説：
* Layer 3 Address Assignment:
* Stack Interface (A): A stack interface is a virtual interface representing all members of a stack.
It can be assigned a Layer 3 IP address for management or routing purposes.
* Loopback (E): Loopback interfaces are virtual interfaces always "up" and used for routing, management, or stable endpoint addressing.
* GRE Tunnels (F): GRE tunnels operate at Layer 3 and require IP addresses for both endpoints to encapsulate and route traffic.
* Why Not Other Options?
* B. VxLAN: VxLAN operates at Layer 2 over Layer 3 and does not require direct IP address assignment to itself.
* C. Virtual LAN: VLANs are Layer 2 constructs; while they are associated with SVI (Switch Virtual Interfaces), they are not directly assigned an IP address.
* D. Virtual Ethernet: Virtual Ethernet interfaces are typically Layer 2 and used within virtualized environments, not directly assigned Layer 3 addresses.

質問 # 25
Which command must be configured at the interface level to honor Differentiated Services Code Point (DSCP)
-based Class of Service (CoS) on a ICX7750?

• A. qos profile
• B. trust dscp
• C. qos-tos map dscp-priority
• D. ip dscp-remark 1

正解：B

解説：
To configure a RUCKUS ICX 7750 switch to honor Differentiated Services Code Point (DSCP)-based Class of Service (CoS) at the interface level, the trust dscp command is used. This command instructs the switch to trust and utilize the DSCP values in incoming packets for Quality of Service (QoS) decisions.
Configuration Steps:
* Access the Switch's Command Line Interface (CLI):
* Use SSH or a direct console connection to access the switch's CLI.
* Enter Global Configuration Mode:
* At the prompt, enter:
enable
configure terminal
* Select the Interface to Configure:
* Specify the interface where DSCP trust should be enabled. For example, to configure Ethernet interface 1/1/1:
interface ethernet 1/1/1

質問 # 26
What are two differences between Class of Service (CoS) and Differentiated Services Code Point (DSCP)?
(Choose two.)

• A. CoS operates at Layer 2 in OSI model, whereas DSCP operates in Layer 3.
• B. CoS defines priority levels and DSCP manipulates traffic according to these defined priority levels.
• C. DSCP defines priority levels and CoS manipulates traffic according to these defined priority levels.
• D. DSCP operates at Layer 2 in OSI model, whereas CoS operates in Layer 3.
• E. DSCP is simpler and can scale easily as the network grows. CoS becomes more complex as network demand for prioritized data increase.

正解：A、E

解説：
Class of Service (CoS) and Differentiated Services Code Point (DSCP) are both mechanisms used to prioritize network traffic, but they function at different layers of the OSI model and have distinct characteristics:
* Operational Layer:
* CoS:
* Operates at Layer 2 (Data Link Layer) of the OSI model.
* Utilizes a 3-bit field within the 802.1Q VLAN tag, known as the Priority Code Point (PCP), to assign priority levels ranging from 0 to 7.
* DSCP:
* Operates at Layer 3 (Network Layer) of the OSI model.
* Uses a 6-bit field in the IP header to assign priority, allowing for up to 64 different values, providing more granularity in traffic classification.
* Scalability and Complexity:
* CoS:
* With only 8 possible priority levels, CoS offers limited granularity.
* As network demands increase, especially with diverse applications requiring different levels of service, managing and differentiating traffic with CoS can become complex due to its limited priority levels.
* DSCP:
* Provides 64 distinct priority levels, allowing for finer differentiation of traffic types.
* This granularity enables easier scalability and more straightforward management of diverse and growing network traffic demands.
References:
* For a detailed comparison between CoS and DSCP, refer to the NetworkLessons Notes on QoS CoS vs DSCP: QoS CoS vs DSCP - NetworkLessons Notes
* For an overview of Differentiated Services and traffic classification, see the article on GeeksforGeeks:
Differentiated Services (DiffServ) and Traffic Classification
Understanding these differences is crucial for network administrators when designing Quality of Service (QoS) policies to ensure efficient and effective traffic management across the network.
