AnSLA (Service Level Agreement)defines performance expectations, includingresponse time, prioritization, and resolution timefor services and support issues. It helps the technician determine which task hashigher priority based on business impact.
* A. NDA (Non-Disclosure Agreement)relates to confidentiality, not task prioritization.
* B. AUP (Acceptable Use Policy)defines user behavior, not issue handling.
* D. MOU (Memorandum of Understanding)outlines informal agreements and doesn't define ticket priorities.

DHCP snooping is a security feature on network switches that helps to prevent unauthorized (rogue) DHCP servers from assigning IP addresses to clients. By implementing DHCP snooping, the network administrator can restrict DHCP responses to authorized servers only, preventing unauthorized DHCP configurations, such as incorrect DNS IPs, from being assigned to clients. This helps prevent man-in-the-middle attacks where malicious actors misconfigure DNS to redirect users to fraudulent sites. (Reference: CompTIA Network+ Study Guide, Chapter on Network Security)

* Definition of MAC Flooding:
* MAC flooding is an attack where a malicious actor sends numerous fake MAC addresses to a switch, overwhelming its CAM table. The CAM table stores MAC addresses and their associated ports for efficient traffic forwarding.
* Impact of MAC Flooding:
* CAM Table Overflow:When the CAM table is full, the switch cannot learn new MAC addresses and is forced to broadcast traffic to all ports, leading to a degraded network performance and potential data interception.
* Switch Behavior:The switch operates in a fail-open mode, treating the network as a hub, which can be exploited for eavesdropping on traffic.
* Comparison with Other Attacks:
* ARP Spoofing:Involves sending false ARP (Address Resolution Protocol) messages to associate the attacker's MAC address with the IP address of another device.
* Evil Twin:Involves creating a rogue wireless access point that mimics a legitimate one to intercept data.
* DNS Poisoning:Involves corrupting the DNS cache with false information to redirect traffic to malicious sites.
* Preventive Measures:
* Port Security:Configure port security on switches to limit the number of MAC addresses per port, preventing CAM table overflow.
* Network Segmentation:Use VLANs to segment network traffic and limit the impact of such attacks.

Port 22 is used for SFTP (Secure File Transfer Protocol) and SCP (Secure Copy Protocol), which encrypt file transfers using SSH (Secure Shell). This ensures data is transmitted securely over the network.
*Why not the other options?
*Port 69 (B) - TFTP (Trivial File Transfer Protocol): Transfers files but is not secure (no encryption).
*Port 80 (C) - HTTP: Used for web traffic, not for file transfer.
*Port 3389 (D) - RDP (Remote Desktop Protocol): Used for remote desktop access, not file transfer.

The user's inability to access the marketing department's shared drives, despite having internet access, suggests a network segmentation issue. The most likely cause is an incorrect VLAN assignment. The computer is physically located on the accounting department floor, and the switchport is likely configured for the accounting VLAN, not the marketing VLAN. VLANs segment network traffic, and if the computer is in the wrong VLAN, it cannot communicate with the marketing department's resources.
Why not Mismatched switchport duplex? Duplex mismatches cause performance issues (e.g., packet loss) but not specific access denials to shared drives.
Why not Misconfigured gateway settings? Incorrect gateway settings would prevent internet access, which the user has.
Why not SVI is assigned to the wrong IP address? A Switch Virtual Interface (SVI) with an incorrect IP address affects inter-VLAN routing, but this would likely impact multiple users, not just one.
Reference:CompTIA Network+ N10-009 Objective 2.2: Explain the purpose of network segmentation and VLAN configuration. The CompTIA Network+ Study Guide (e.g., Chapter 6: Switching) explains that VLANs isolate traffic, and incorrect VLAN assignments prevent access to resources on other VLANs.
