NEW QUESTION # 12
Which device is an Internet of Things (IoT) device?
Answer: A
Explanation:
An Internet of Things device is a physical endpoint with embedded connectivity that can collect, send, or receive data over a network. An internet-accessible thermostat matches that definition because it is a connected smart device used in the physical environment.
NEW QUESTION # 13
Which address is a link-local IPv6 address?
Answer: D
Explanation:
An IPv6 link-local address is a unicast address used for communication between devices connected to the same local network segment.
According to Cisco ' s official Understand the IPv6 Link-Local Address documentation:
A Link-Local address is an IPv6 unicast address
Cisco specifies the reserved IPv6 link-local prefix as FE80::/10. This prefix identifies addresses used for local- link communication, including Neighbor Discovery Protocol (NDP), Stateless Address Autoconfiguration (SLAAC), and communication between neighboring IPv6 devices.
Link-local addresses can be automatically generated when IPv6 is enabled on an interface or manually configured by an administrator.
These addresses are not routable beyond their local link. IPv6 routers must not forward packets containing link-local source or destination addresses to another network segment.
Why the other options are incorrect:
A). fe80::261:2eff:fe10:7561 - Correct. Belongs to the FE80::/10 link-local address range.
B). ff01:0:0:0:0:0:0:2 - Incorrect. An IPv6 multicast address, specifically the interface-local all-routers multicast address.
C). 2001:db8:85a3:8d3:1319:8a2e:370:7348 - Incorrect. Belongs to the 2001:DB8::/32 documentation prefix, not the link-local range.
D). fdf8:f535:82e4::53 - Incorrect. Belongs to the FC00::/7 unique local unicast address range.
Therefore, Option A is correct.

NEW QUESTION # 15
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?
Answer: A
Explanation:
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.

NEW QUESTION # 16
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.
Answer:
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.
