Cisco Certified Support Technician (CCST) NetworkingExam 認定 CCST-Networking 試験問題 (Q33-Q38):

質問 # 33
A help desk technician receives the four trouble tickets listed below. Which ticket should receive the highest priority and be addressed first?

A. 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.
B. Ticket 2: An online webinar is taking place in the conference room. The video conferencing equipment lost internet access.
C. Ticket 3: A user reports that response time for a cloud-based application is slower than usual.
D. Ticket 4: Two users report that wireless access in the cafeteria has been down for the last hour.

正解：B

解説：
When prioritizing trouble tickets, the most critical issues affecting business operations or high-impact activities should be addressed first. Here's a breakdown of the tickets:
* Ticket 1: Relocation of a printer, while necessary, is not urgent and does not impact critical operations.
* Ticket 2: An ongoing webinar losing internet access is critical, especially if the webinar is time-sensitive and involves multiple participants.
* Ticket 3: Slower response time for a cloud-based application is important but typically not as urgent as a complete loss of internet access for a live event.
* Ticket 4: Wireless access down in the cafeteria affects users but does not have the same immediate impact as a live webinar losing connectivity.
Thus, the correct answer is B. Ticket 2: An online webinar is taking place in the conference room. The video conferencing equipment lost internet access.

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 floods the frame out all active ports except port G0/1.
B. Switch1 queries Switch2 for the MAC address of PC-C.
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：C

解説：
In a network, when a Layer 2 switch (like Switch1) receives a frame destined for a MAC address that is not in its MAC address table, it performs a flooding operation. This means the switch will send the frame out of all ports except the port on which the frame was received. This flooding ensures that if the destination device is connected to one of the other ports, it will receive the frame and respond, allowing the switch to learn its MAC address.
* A. Switch1 queries Switch2 for the MAC address of PC-C: This does not happen in Layer 2 switches; they do not query other switches for MAC addresses.
* A. Switch1 drops the frame and sends an error message back to PC-A: This is not the default behavior for unknown unicast frames.
* D. Switch1 sends an ARP request to obtain the MAC address of PC-C: ARP is used by devices to map IP addresses to MAC addresses, not by switches to find unknown MAC addresses.
Thus, the correct answer is B. Switch1 floods the frame out all active ports except port G0/1.

質問 # 35
You plan to use a network firewall to protect computers at a small office.
For each statement about firewalls, select True or False.
Note: You will receive partial credit for each correct selection.

正解：

解説：

Explanation:
* A firewall can direct all web traffic to a specific IP address.
* True: Firewalls can be configured to perform Network Address Translation (NAT) and port forwarding, which can direct all web traffic (typically on port 80 and 443) to a specific internal IP address.
* A firewall can block traffic to specific ports on internal computers.
* True: Firewalls can be configured with access control lists (ACLs) or rules to block traffic to specific ports on internal computers, enhancing security by restricting unwanted or harmful traffic.
* A firewall can prevent specific apps from running on a computer.
* False: Firewalls typically control traffic flow and do not prevent specific applications from running on a computer. Application control is usually managed by endpoint security software or application control systems.
* Directing Web Traffic: Firewalls can manage traffic redirection using NAT and port forwarding rules to route web traffic to designated servers or devices within the network.
* Blocking Specific Ports: Firewalls can enforce security policies by blocking or allowing traffic based on port numbers, ensuring that only permitted traffic reaches internal systems.
* Application Control: While firewalls manage network traffic, preventing applications from running typically requires software specifically designed for endpoint protection and application management.

質問 # 36
A support technician examines the front panel of a Cisco switch and sees 4 Ethernet cables connected in the first four ports. Ports 1, 2, and 3 have a green LED. Port 4 has a blinking green light.
What is the state of the Port 4?

A. Link is up and there is no activity.
B. Link is up and not stable.
C. Link is up with cable malfunctions.
D. Link is up and active.

正解：D

解説：
On a Cisco switch, a port with a blinking green LED typically indicates that the port is up (active) and is currently transmitting or receiving data. This is a normal state indicating active traffic on the port.
*A. Link is up with cable malfunctions: Usually indicated by an amber or blinking amber light.
*B. Link is up and not stable: Not typically indicated by a green blinking light.
*D. Link is up and there is no activity: Would be indicated by a solid green light withoutblinking.
Thus, the correct answer is C. Link is up and active.

質問 # 37
What is the most compressed valid format of the IPv6 address 2001 :0db8:0000:0016:0000:001b: 2000:0056?

A. 2001:db8: 0:16: :1b: 2000:56
B. 2001:db8: 16: :1b:2:56
C. 2001:db8: : 16: : 1b:2:56
D. 2001:db8: : 16: : 1b: 2000: 56

正解：A

解説：
IPv6 addresses can be compressed by removing leading zeros and replacing consecutive groups of zeros with a double colon (::). Here's how to compress the address 2001:0db8:0000:0016:0000:001b:2000:0056:
* Remove leading zeros from each segment:
* 2001:db8:0000:0016:0000:001b:2000:0056 becomes 2001:db8:0:16:0:1b:2000:56
* Replace the longest sequence of consecutive zeros with a double colon (::). In this case, the two consecutive zeros between the 16 and 1b:
* 2001:db8:0:16::1b:2000:56
Thus, the most compressed valid format of the IPv6 address is 2001:db8:0:16::1b:2000:56.
