Correct Answer: D

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:

Replace the longest sequence of consecutive zeros with a double colon (::). In this case, the two consecutive zeros between the 16 and 1b:

Thus, the most compressed valid format of the IPv6 address is 2001:db8:0:16::1b:2000:56.

IPv6 Addressing (Cisco)

Correct Answer: AD

The private IP address ranges that are set aside specifically for use within private networks and not routable on the internet are as follows: Class A: 10.0.0.0 to 10.255.255.255 Class B: 172.16.0.0 to 172.31.255.255 Class C: 192.168.0.0 to 192.168.255.255 These ranges are defined by the Internet Assigned Numbers Authority (IANA) and are used for local communications within a private network123. Given the options: A.172.16.0.0 to 172.31.255.255falls within the Class B private range. B.

192.16.0.0 to 192.16.255.255is not a recognized private IP range. C.11.0.0.0 to 11.255.255.255is not a recognized private IP range. D.192.168.0.0 to 192.168.255.255 falls within the Class C private range.

Therefore, the correct selections that the company should use for their private networks are AandD.

Correct Answer: AC

-Statement A: "The trace successfully reached the www.cisco.com server." This is true as indicated by the "Trace complete" message at the end, showing that the trace has reached its destination. -Statement C: "The IPv6 address associated

with the www.cisco.com server is 2600:1408:c400:38d::b33." This is true because the final hop in the trace, which is the destination, has this IPv6 address.

-Statement B: "The trace failed after the fourth hop." This is incorrect as the trace continues beyond the fourth hop, despite some intermediate timeouts. -Statement D: "The routers at hops 5 and 6 are offline." This is not necessarily true. The

routers might be configured to not respond to traceroute requests.

-Statement E: "The device sending the trace has IPv6 address 2600:1408:c400:38d::b33."

This is incorrect; this address belongs to the destination server, not the sender.

Correct Answer: B

The tracert command is used to determine the route taken by packets across an IP network. When a user reports that an external web page is not loading, while other resources are accessible, it suggests there might be an issue at a certain

point in the network path to the specific web page. The tracert command helps to diagnose where the breakdown occurs by displaying a list of routers that the packets pass through on their way to the destination. It can identify the network

segment where the packets stop progressing,

which is valuable for pinpointing where the connectivity issue lies. References := Cisco

-nslookup: This command queries the DNS to obtain domain name or IP address mapping,

useful for DNS issues but not for tracing network paths.

Correct Answer: C

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.

Correct Answer: B

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.

The correct matching of the MFA factors to their examples is as follows:

Entering a one-time security code sent to your device after logging in: Possession Holding your phone to your face to be recognized: Inherence Specifying your user name and password to log on to a service: Knowledge Here's why each

factor matches the example:

Possession: This factor is something the user has, like a mobile device. A one- time security code sent to this device falls under this category. Inherence: This factor is something the user is, such as a biometric characteristic. Facial

recognition using a phone is an example of this factor. Knowledge: This factor is something the user knows, like a password or PIN. Multi-Factor Authentication (MFA) enhances security by requiring two or more of these factors to verify a

user's identity before granting access.

Entering a one-time security code sent to your device after logging in. Holding your phone to your face to be recognized. Specifying your username and password to log on to a service.

Possession Factor: This involves something the user has in their possession. Receiving a one-time security code on a device (e.g., phone) is an example of this. Inference Factor (Inherence/Biometric): This involves something inherent to the

user, such as biometric verification (e.g., facial recognition or fingerprint scanning). Knowledge Factor: This involves something the user knows, such as login credentials (username and password).

Correct Answer:

The correct matching of the security options to their characteristics is as follows:

WPA2-Enterprise: Uses a RADIUS server for authentication WEP: Uses a minimum of 40 bits for encryption

WPA2-Personal: Uses AES and a pre-shared key for authentication Here's why each security option matches the characteristic:

WPA2-Enterpriseuses a RADIUS server for authentication, which provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.

WEP (Wired Equivalent Privacy)is an outdated security protocol that uses a minimum of 40 bits for encryption (and up to 104 bits), which is relatively weak by today's standards.

WPA2-Personal(Wi-Fi Protected Access 2 - Personal) uses the Advanced Encryption Standard (AES) for encryption and a pre-shared key (PSK) for authentication, which is shared among users to access the network. These security options

are essential for protecting wireless networks from unauthorized access and ensuring data privacy.

Correct Answer:

A firewall can direct all web traffic to a specific IP address. A firewall can block traffic to specific ports on internal computers. A firewall can prevent specific apps from running on a computer.

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.

Correct Answer:

Statement 1: Low bandwidth can increase network latency. Statement 2: High levels of network latency decrease network bandwidth. Statement 3: You can increase throughput by decreasing network latency.

Bandwidth vs. Latency: Bandwidth refers to the maximum rate at which data can be transferred over a network path. Latency is the time it takes for a data packet to travel from the source to the destination.
