Cisco Certified Support Technician (CCST) NetworkingExam 認定 CCST-Networking 試験問題 (Q21-Q26):

質問 # 21
A help desk technician receives the four trouble tickets listed below. Which ticket should receive the highest priority and be addressed first?

A. Ticket 3: A user reports that response time for a cloud-based application is slower than usual.
B. Ticket 2: An online webinar is taking place in the conference room. The video conferencing equipment lost internet access.
C. Ticket 4: Two users report that wireless access in the cafeteria has been down for the last hour.
D. Ticket 1: A user requests relocation of a printer to a different network jack in the same office. The jack must be patched and made active.

正解：B

質問 # 22
A Cisco PoE switch is shown in the following image. Which type of port will provide both data connectivity and power to an IP phone?

A. Port identified with number 2
B. Ports identified with number 6
C. Ports identified with number 7
D. Ports identified with numbers 3 and 4

正解：B

解説：
In the provided image of the Cisco PoE switch, the ports identified with number 6 are the standard RJ-45 Ethernet ports typically found on switches that provide both data connectivity and Power over Ethernet (PoE).
PoE ports are designed to supply power to devices such as IP phones, wireless access points, and other PoE-enabled devices directly through the Ethernet cable.
Ports:
*2: Console port (for management and configuration)
*3 and 4: Specific function ports (often for management)
*6: RJ-45 Ethernet ports (capable of providing PoE)
*7: SFP ports (for fiber connections, typically do not provide PoE)
Thus, the correct answer is C. Ports identified with number 6.

質問 # 23
In the network shown in the following graphic, Switch1 is a Layer 2 switch.

PC-A sends a frame to PC-C. Switch1 does not have a mapping entry for the MAC address of PC-C. Which action does Switch1 take?

A. Switch1 queries Switch2 for the MAC address of PC-C.
B. Switch1 floods the frame out all active ports except port G0/1.
C. Switch1 drops the frame and sends an error message back to PC-A.
D. Switch1 sends an ARP request to obtain the MAC address of PC-C.

正解：B

解説：
Understanding How Layer 2 Switches Handle Unknown MAC Addresses
Switches operate atLayer 2 (Data Link Layer)of the OSI model and maintain aMAC address table (CAM table)to forward frames efficiently.
* When a switch receives a frame, itchecks its MAC address tableto see if it knows the destination MAC address.
* If the destinationMAC address is not in the table(meaning the switch does not know which port leads to PC-C), the switch follows theflooding behavior.
What Happens When Switch1 Receives a Frame from PC-A to PC-C?
* Switch1 checks its MAC table:
* The source MAC (PC-A) is recorded in the table on portG0/1.
* The destination MAC (PC-C)is not in the table.
* Switch1 does not know where PC-C is:
* Itfloodsthe frame out of allactive ports except the port it was received on (G0/1).
* This means the frame is sent to:
* Switch2 (via G0/23)
* PC-B (via G0/2)
* Switch2 receives the frame and follows the same process:
* If Switch2 has PC-C's MAC in its table, it forwards the frame appropriately.
* If not,it floodsthe frame again until PC-C replies.
* Once PC-C responds, Switch1 and Switch2 learn its MAC address and update their tables.
Why Other Options Are Incorrect:
#A. Switch1 queries Switch2 for the MAC address of PC-C.
* Incorrect:Switches do not query other switches directly for MAC addresses. Instead, they rely on learning MAC addresses dynamically through frame forwarding.
#B. Switch1 drops the frame and sends an error message back to PC-A.
* Incorrect:Switchesdo not drop frames for unknown MAC addresses. Instead, theyfloodthe frames out all ports except the incoming port.
#D. Switch1 sends an ARP request to obtain the MAC address of PC-C.
* Incorrect:
* ARP (Address Resolution Protocol)is only used to resolve IP addresses to MAC addresses.
* Since PC-A issending a frame (Layer 2), not an IP packet (Layer 3), ARP isnot involvedhere.
Conclusion
Since Switch1does not know the destination MAC address, itfloods the frame out all active ports except the port it was received on. This is the default behavior of Layer 2 switches when they encounter an unknown MAC address.
Thus, thecorrect answer is:#C. Switch1 floods the frame out all active ports except port G0/1.

質問 # 24
Which information is included in the header of a UDP segment?

A. IP addresses
B. Sequence numbers
C. Port numbers
D. MAC addresses

正解：C

解説：
The header of a UDP (User Datagram Protocol) segment includesport numbers. Specifically, it contains the source port number and the destination port number, which are used to identify the sending and receiving applications. UDP headers do not include IP addresses or MAC addresses, as those are part of the IP and Ethernet frame headers, respectively.Additionally, UDP does not use sequence numbers, which are a feature of TCP (Transmission Control Protocol) for ensuring reliable delivery of data segments1.
References:=
* Segmentation Explained with TCP and UDP Header
* User Datagram Protocol (UDP) - GeeksforGeeks
* Which three fields are used in a UDP segment header
* UDP Header: The header of a UDP segment includes the following key fields:
* Source Port: The port number of the sending application.
* Destination Port: The port number of the receiving application.
* Length: The length of the UDP header and data.
* Checksum: Used for error-checking the header and data.
* IP Addresses: These are included in the IP header, not the UDP header.
* Sequence Numbers: These are part of the TCP header, not UDP.
* MAC Addresses: These are part of the Ethernet frame header and are not included in the UDP header.

質問 # 25
Which device protects the network by permitting or denying traffic based on IP address, port number, or application?

A. VPN gateway
B. Firewall
C. Intrusion detection system
D. Access point

正解：B

解説：
* Firewall: A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It permits or denies traffic based on IP addresses, port numbers, or applications.
* Access Point: This is a device that allows wireless devices to connect to a wired network using Wi-Fi.
It does not perform traffic filtering based on IP, port, or application.
* VPN Gateway: This device allows for secure connections between networks over the internet, but it is not primarily used for traffic filtering based on IP, port, or application.
* Intrusion Detection System (IDS): This device monitors network traffic for suspicious activity and policy violations, but it does not actively permit or deny traffic.
