An SLA (Service Level Agreement) is a document that defines the expected level of service and performance guaranteed by a service provider to a customer. It usually specifies metrics such as uptime, availability, reliability, response time, and compensation or penalties for not meeting the agreed standards. An SLA is a way of ensuring that both parties are clear about their roles and responsibilities, and that the customer receives the quality of service they paid for.

802.11b is a wireless networking standard that operates on the 2.4 GHz frequency band. It supports a maximum data rate of 11 Mbps and has a range of about 35 meters indoors and 140 meters outdoors. 802.11b is compatible with older smart-plug devices that use the same frequency band, but it may suffer from interference from other devices that also use the 2.4 GHz band, such as microwave ovens, Bluetooth devices, and cordless phones.

PAT (Port Address Translation) is a type of Network Address Translation (NAT) that allows multiple devices to share a single public IP address by using different port numbers. PAT enables devices to access the internet without exposing their private IP addresses. A router is a device that can perform PAT by translating the source IP address and port number of outgoing packets and the destination IP address and port number of incoming packets. A Layer 3 switch is a device that can perform basic routing functions by using IP addresses, but it cannot perform PAT or other advanced routing features that a router can.

A split-tunnel VPN is a VPN feature that allows remote users to access network resources while only redirecting necessary traffic through the VPN tunnel. A split-tunnel VPN enables users to choose which applications or websites to secure with the VPN and which to connect normally through the internet. This can improve performance, conserve bandwidth, and avoid compatibility issues with some services that depend on the user's location. A split-tunnel VPN can also allow users to access local devices or resources that are not accessible through the VPN.

Multifactor authentication is a method of verifying a user's identity by requiring more than one factor, such as something the user knows, something the user has, or something the user is. A password is something the user knows, and a fingerprint is something the user is. Therefore, a user who needs to enter a password and scan a fingerprint is using multifactor authentication.

STP (Spanning Tree Protocol) is a protocol that prevents loops in a network by placing some of the switch ports in different states, such as blocking, listening, learning, forwarding, or disabled. A port in the blocking state does not forward frames or participate in frame forwarding. A network engineer can reconfigure STP to change the port states and avoid blocking ports that are needed for trunking.

A captive portal is a web page that is displayed to newly connected users of a Wi-Fi network before they are granted broader access to network resources.Captive portals are commonly used to present a landing or log-in page which may require authentication, payment, acceptance of an end-user license agreement, acceptable use policy, survey completion, or other valid credentials that both the host and user agree to adhere by123

A possible cause of the issue is that the user has not completed the captive portal authentication process, which prevents the VPN from establishing a secure connection over the Wi-Fi network. The user may need to open a web browser and follow the instructions on the captive portal page to gain full access to the internet.

The route command is used to view and manipulate the IP routing table in Windows operating systems456The routing table contains information about how to reach different network destinations. The output from the workstation shows that the routing table does not have a default gateway, which is a router that forwards packets to other networks that are not directly connected to the local network. A default gateway is usually specified by a route with a destination of 0.0.0.0 and a netmask of 0.0.0.0, which matches any IP address.

To correct the issue, the technician can use the route ADD command to add a default gateway to the routing table. The syntax of the command is:

route ADD <destination> MASK <netmask> <gateway> metric <metric>

The destination and netmask parameters should be 0.0.0.0 to indicate a default route. The gateway parameter should be the IP address of the router that can reach the internet, which is 10.10.51.10 in this case. The metric parameter is an optional value that indicates the cost or preference of the route, which can be used to choose between multiple routes to the same destination. A lower metric means a higher preference. The metric parameter can be any integer between 1 and 9999. In this case, the metric parameter can be 35 or any other value.

Therefore, the correct command is:

route ADD 0.0.0.0 MASK 0.0.0.0 10.10.51.10 metric 35

A peer-to-peer network is a type of network in which each computer (or node) can communicate directly with any other node, without requiring a central server or authority. Each node can act as both a client and a server, and can share its own resources, such as files, printers, or internet connection, with other nodes.A peer-to-peer network allows users to directly access and exchange what is on or attached to their computers, with equal permissions and responsibilities
