問題 #60
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?

答案:A

解題說明:
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.
References :=
*Cisco Traceroute Command
*Understanding Traceroute
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.

問題 #61
Examine the output of the show mac-address-tablecommand on a Cisco 24 port Ethernet switch.

What can you determine about this switch from the command output?

答案:C

解題說明:
Multiple different MAC addresses in several VLANs are being learned on port Gig0/1, which indicates that this port is forwarding traffic for multiple devices beyond the local switch. That behavior is typical of a connection to another switch.


問題 #62
What is the purpose of VLANs in a switched network environment within an enterprise organization?

答案:A

解題說明:
VLANs logically divide a network into separate broadcast domains, improving security, performance, and management without requiring additional physical infrastructure.


問題 #63
During the data encapsulation process, which OSI layer adds a header that contains MAC addressing information and a trailer used for error checking?

答案:C

解題說明:
The Data Link layer adds the MAC address header and a trailer containing the frame check sequence for error detection.


問題 #64
HOTSPOT
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.

答案:

解題說明:

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.
