RUCKUS Certified Networking Implementer Sample Questions (Q55-Q60):

NEW QUESTION # 55
Which two ICX switch models are recommended for collapsed aggregation and core network designs?
(Choose two.)

A. ICX7850
B. ICX7450
C. ICX7550
D. ICX7250
E. ICX7750

Answer: A,E

Explanation:
In network architecture, a collapsed aggregation and core design consolidates the aggregation and core layers into a single layer, simplifying the network and reducing latency. RUCKUS ICX switch models suitable for such designs include:
* ICX7850:
* Overview:
* A high-performance, stackable switch designed for enterprise aggregation and core layers.
* Key Features:
* Supports up to 32 ports of 40/100 GbE, providing high-density connectivity.
* Advanced stacking capabilities, allowing up to 12 switches to be stacked together for simplified management and scalability.
* Dual hot-swappable power supplies and fans, ensuring high availability and reliability.
* Use Case:
* Ideal for organizations seeking to implement a collapsed core architecture with high bandwidth requirements and simplified network management.

NEW QUESTION # 56
Which function is performed by ARP protocol?

A. build and maintain switch MAC tables
B. discover directly connected neighbors
C. resolve IP address to MAC address
D. resolve host name

Answer: C

Explanation:
The Address Resolution Protocol (ARP) is a fundamental protocol used in IP networking to map a device's IP address to its corresponding Media Access Control (MAC) address. This mapping is essential for enabling communication within a local network segment.
How ARP Works:
* ARP Request:
* When a device (Host A) needs to communicate with another device (Host B) on the same local network, it checks its ARP cache to see if it already has Host B's MAC address corresponding to its IP address.
* If the MAC address is not in the cache, Host A broadcasts an ARP request packet to all devices on the local network. This packet includes Host B's IP address and requests the MAC address associated with that IP.
* ARP Reply:
* Upon receiving the ARP request, the device with the matching IP address (Host B) responds with an ARP reply. This reply is sent directly to Host A and contains Host B's MAC address.
* Updating ARP Cache:
* Host A receives the ARP reply and updates its ARP cache with the new IP-to-MAC address mapping. This cached information allows for efficient communication without the need for repeated ARP requests.
Key Functions of ARP:
* IP to MAC Address Resolution:
* ARP's primary function is to resolve IP addresses to MAC addresses, enabling devices to locate each other on the same local network segment.
* Facilitating Data Link Layer Communication:
* By providing the necessary MAC address, ARP allows data packets to be correctly addressed and transmitted over the network's data link layer.
Clarifications on Other Options:
* Option B: Discover directly connected neighbors
* This function is typically performed by protocols like the Neighbor Discovery Protocol (NDP) in IPv6 or by network discovery tools, not by ARP.
* Option C: Build and maintain switch MAC tables
* Switches build and maintain MAC address tables by observing the source MAC addresses of incoming frames, a process independent of ARP.
* Option D: Resolve host name
* Resolving hostnames to IP addresses is the function of the Domain Name System (DNS), not ARP.

NEW QUESTION # 57
Which three objects can be assigned a Layer 3 address? (Choose three.)

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

Answer: A,B,F

NEW QUESTION # 58
What is the maximum number of software images that can be stored simultaneously on an ICX switch?

A. 0
B. 1
C. 2
D. 3

Answer: D

Explanation:
RUCKUS ICX switches are designed to store multiple software images simultaneously, allowing network administrators to manage firmware versions effectively. The maximum number of software images that can be stored on an ICX switch is three.
Image Storage Structure:
* Primary Image:
* The main firmware image that the switch loads during the boot process.
* Secondary Image:
* An alternative firmware image that can be used for redundancy or testing purposes.
* Tertiary (or Additional) Image:
* A third firmware image slot available for further flexibility in image management.
Managing Software Images:
* Viewing Stored Images:
* To display the software images stored on the switch, use the following command:
sql
Copy code
show flash
* This command lists all firmware images present in the switch's flash memory.
* Setting Boot Preferences:
* To specify which image the switch should load on the next reboot, use:
sql
Copy code
boot system flash primary
* Replace primary with secondary or tertiary as needed.
* Upgrading Firmware:
* When upgrading the switch firmware, you can upload the new image to any of the available slots (primary, secondary, or tertiary) without overwriting existing images, providing a fallback option if needed.
Best Practices:
* Maintain Multiple Images:
* Keeping multiple firmware images allows for quick recovery in case of issues with the current running image.
* Regular Updates:
* Ensure that the stored images are up-to-date to maintain security and feature enhancements.
* Consistent Configuration:
* After uploading a new image, verify that the switch configuration is compatible with the firmware version to prevent potential issues.
