Cisco Certified Support Technician (CCST) Networking 認定 100-150 試験問題 (Q32-Q37):

質問 # 32
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 drops the frame and sends an error message back to PC-A.
C. Switch1 floods the frame out all active ports except port G0/1.
D. Switch1 sends an ARP request to obtain the MAC address of PC-C.

正解：C

解説：
Understanding How Layer 2 Switches Handle Unknown MAC Addresses
Switches operate at Layer 2 (Data Link Layer) of the OSI model and maintain a MAC address table (CAM table) to forward frames efficiently.
* When a switch receives a frame, it checks its MAC address table to see if it knows the destination MAC address.
* If the destination MAC address is not in the table (meaning the switch does not know which port leads to PC-C), the switch follows the flooding 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 port G0/1.
* The destination MAC (PC-C) is not in the table.
* Switch1 does not know where PC-C is:
* It floods the frame out of all active 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 floods the 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: Switches do not drop frames for unknown MAC addresses. Instead, they flood the 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 is sending a frame (Layer 2), not an IP packet (Layer 3), ARP is not involved here.
Conclusion
Since Switch1 does not know the destination MAC address, it floods 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, the correct answer is:# C. Switch1 floods the frame out all active ports except port G0/1.

質問 # 33
A user reports that a company website is not available. The help desk technician issues a tracert command to determine if the server hosting the website is reachable over the network. The output of the command is shown as follows:

What can you tell from the command output?

A. The server address 192.168.1.10 is being blocked by a firewall on the router at hop 3.
B. The server with the address 192.168.1.10 is reachable over the network.
C. Requests to the web server at 192.168.1.10 are being delayed and time out.
D. The router at hop 3 is not forwarding packets to the IP address 192.168.1.10.

正解：B

解説：
The tracert command output shows the path taken to reach the destination IP address, 192.168.1.10. The command output indicates:
*Hops 1 and 2 are successfully reached.
*Hop 3 times out, meaning the router at hop 3 did not respond to the tracert request. However, this does not necessarily indicate a problem with forwarding packets, as some routers may be configured to block or not respond to ICMP requests.
*Hops 4 and 5 are successfully reached, with hop 5 being the destination IP 192.168.1.10, indicating that the server is reachable.
Thus, the correct answer is C. The server with the address 192.168.1.10 is reachable over the network.

The tracert command output indicates that the server with the address 192.168.1.10 is reachable over the network. The asterisk (*) at hop 3 suggests that the probe sent to that hop did not return a response, which could be due to a variety of reasons such as a firewall blocking ICMP packets or the router at that hop being configured not to respond to ICMP requests. However, since the subsequent hops (4 and 5) are showing response times, it means that the packets are indeed getting through and the server is reachable12.

質問 # 34
Which protocol allows you to securely upload files to another computer on the internet?

A. SFTP
B. HTTP
C. NTP
D. ICMP

正解：A

解説：
SFTP, or Secure File Transfer Protocol, is a protocol that allows for secure file transfer capabilities between networked hosts. It is a secure extension of the File Transfer Protocol (FTP). SFTP encrypts both commands and data, preventing passwords and sensitive information from being transmitted openly over the network. It is typically used for secure file transfers over the internet and is built on the Secure Shell (SSH) protocol1.
Reference: =
* What Is SFTP? (Secure File Transfer Protocol)
* How to Use SFTP to Safely Transfer Files: A Step-by-Step Guide
* Secure File Transfers: Best Practices, Protocols And Tools
The Secure File Transfer Protocol (SFTP) is a secure version of the File Transfer Protocol (FTP) that uses SSH (Secure Shell) to encrypt all commands and data. This ensures that sensitive information, such as usernames, passwords, and files being transferred, are securely transmitted over the network.
* ICMP (Internet Control Message Protocol) is used for network diagnostics and is not designed for file transfer.
* NTP (Network Time Protocol) is used to synchronize clocks between computer systems and is not related to file transfer.
* HTTP (HyperText Transfer Protocol) is used for transmitting web pages over the internet and does not inherently provide secure file transfer capabilities.
Thus, the correct protocol that allows secure uploading of files to another computer on the internet is SFTP.

質問 # 35
Which device protects the network by permitting or denying traffic based on IP address, port number, or application?

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

正解：C

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.

質問 # 36
During the data encapsulation process, which OSI layer adds a header that contains MAC addressing information and a trailer used for error checking?

A. Data Link
B. Network
C. Session
D. Transport

正解：A

解説：

OSI model
During the data encapsulation process, the Data Link layer of the OSI model is responsible for adding a header that contains MAC addressing information and a trailer used for error checking. The header typically includes the source and destination MAC addresses, while the trailer contains a Frame Check Sequence (FCS) which is used for error detection1.
The Data Link layer ensures that messages are delivered to the proper device on a LAN using hardware addresses and translates messages from the Network layer into bits for the Physical layer to transmit. It also controls how data is placed onto the medium and is received from the medium through the physical hardware.
