CompTIA Updated N10-008 Exam Questions and Answers by quinn

• A service set identifier (SSID) is a name that identifies a wireless network12.
• A wireless network can have multiple SSIDs, each with different settings and security parameters, to create separate logical networks for different purposes or users12.
• However, having multiple SSIDs can also create some challenges, such as increased management overhead, reduced bandwidth, and interference12.
• A technician can consolidate a topology with multiple SSIDs into one unique SSID deployment, by using a single SSID for the entire wireless network and applying different policies or profiles based on other criteria, such as user roles, device types, or locations12.
• One of the benefits of having a unique SSID deployment is that it enables seamless roaming, which is the ability of a wireless device to move from one access point (AP) to another without losing connectivity or experiencing delays12.
• Seamless roaming is possible after this new configuration, because the device does not need to scan for and authenticate with different SSIDs as it moves across the network, but can simply switch to the best available AP that shares the same SSID12.
• The other options are not features that will be possible after this new configuration, because they are either unrelated or unaffected by the SSID deployment:

A zero-day attack refers to an attack that exploits a previously unknown vulnerability in a software or system, which developers have had zero days to fix. In this scenario, the attacker is using an unknown vulnerability in the print spooler to gain elevated system privileges, which is a classic example of a zero-day attack. This term specifically denotes the unexpected nature of the attack and the absence of a patch or workaround at the time of discovery. Honeypots, internal threats, and external threats refer to different aspects of cybersecurity and do not specifically describe the exploitation of unknown vulnerabilities​​.

A frame is a unit of data that is transmitted at the data link layer of the OSI model. A frame consists of a header, a payload, and a trailer. The header contains information such as the source and destination MAC addresses, the frame type, and the error detection code. The payload contains the data from the upper layer protocols, such as IP packets. The trailer contains the frame check sequence, which is used to verify the integrity of the frame. A switch is a device that operates at the data link layer of the OSI model. A switch forwards frames based on the MAC addresses of the devices connected to its ports. A switch can create separate collision domains and reduce network congestion. A switch can also implement VLANs, which are logical groups of devices that share the same broadcast domain, regardless of their physical location. A session is a logical connection between two or more devices that allows the exchange of data at the transport layer of the OSI model. A session is not a device or an encapsulation at the data link layer. A firewall is a device that operates at the network layer or the application layer of the OSI model. A firewall filters packets based on the IP addresses, ports, protocols, or application rules. A firewall is not a device or an encapsulation at the data link layer. A packet is a unit of data that is transmitted at the network layer of the OSI model. A packet consists of a header and a payload. The header contains information such as the source and destination IP addresses, the protocol type, and the hop count. The payload contains the data from the upper layer protocols, such as TCP segments. A packet is not an encapsulation at the data link layer. A router is a device that operates at the network layer of the OSI model. A router forwards packets based on the IP addresses and the routing table. A router can create separate broadcast domains and connect different networks. A router is not a device or an encapsulation at the data link layer. References: CompTIA Network+ N10-008 Cert Guide, Chapter 2, Section 2.2 and CompTIA Network+ N10-008 Cert Guide, Chapter 3, Section 3.1

Installing cameras in the server room is the best solution to identify who is responsible for the equipment being moved and misplaced. Cameras provide a way to monitor the server room in real time and can be used to identify suspicious activity. Additionally, they provide a way to review past activity and allow you to review footage to determine who may be responsible for the misplacement of equipment.
