54 Segmentation, sequencing, and error checking all occur at what layer of the OSI model that is associated with SSL, TLS, and UDP?The Transport layerThe Network layerThe Session layerThe Presentation layer
55 The Windows ipconfig command displays the following information:BC-5F-F4-7B-4B-7DWhat term describes this, and what information can usually be gathered from it?The IP address, the network location of the systemThe MAC address, the network interface card's manufacturerThe MAC address, the media type in useThe IPv6 client ID, the network interface card's manufacturer
56 Chris has been asked to choose between implementing PEAP and LEAP for wireless authentication. What should he choose, and why?LEAP, because it fixes problems with TKIP, resulting in stronger securityPEAP, because it implements CCMP for securityLEAP, because it implements EAP-TLS for end-to-end session encryptionPEAP, because it can provide a TLS tunnel that encapsulates EAP methods, protecting the entire session
57 Ben is troubleshooting a network and discovers that the NAT router he is connected to has the 192.168.x.x subnet as its internal network and that its external IP is 192.168.1.40. What problem is he encountering?192.168.x.x is a nonroutable network and will not be carried to the internet.192.168.1.40 is not a valid address because it is reserved by RFC 1918.Double NATing is not possible using the same IP range.The upstream system is unable to de-encapsulate his packets, and he needs to use PAT instead.

60 What technical difference separates wireless communication via WiFi and LiFi?LiFi is not susceptible to electromagnetic interference.LiFi cannot be used to deliver broadband speeds.WiFi is not susceptible to electromagnetic interference.WiFi cannot be used to deliver broadband speeds.
61 Selah's organization has deployed VoIP phones on the same switches that the desktop PCs are on. What security issue could this create, and what solution would help?VLAN hopping; use physically separate switches.VLAN hopping; use encryption.Caller ID spoofing; MAC filtering.Denial-of-service attacks; use a firewall between networks.For questions 62–65, please refer to the following scenario:Susan is designing her organization's new network infrastructure for a branch office.
62 Susan wants to use a set of nonroutable IP addresses for the location's internal network addresses. Using your knowledge of secure network design principles and IP networking, which of the following IP ranges are usable for that purpose? (Select all that apply.)172.16.0.0/12192.168.0.0/16128.192.0.0/2410.0.0.0/8
63 Susan knows that she will need to implement a WiFi network for her customers and wants to gather information about the customers, such as their email address, without having to provide them with a wireless network password or key. What type of solution would provide this combination of features?NACA captive portalPre-shared keysWPA3's SAE mode
64 With her wireless network set up, Susan moves on to ensuring that her network will remain operational even if disruptions occur. What is the simplest way she can ensure that her network devices, including her router, access points, and network switches, stay on if a brownout or other temporary power issue occurs?Purchase and install a generator with an automatic start.Deploy dual power supplies for all network devices.Install UPS systems to cover all network devices that must remain online.Contract with multiple different power companies for redundant power.
65 Susan wants to provide 10 gigabit network connections to devices in the facility where the new branch will operate. What connectivity options does she have for structured wiring that can meet those speeds? (Select all that apply.)Cat5eFiberCat6Coaxial cable
66 Data streams occur at what three layers of the OSI model?Application, Presentation, and SessionPresentation, Session, and TransportPhysical, Data Link, and NetworkData Link, Network, and Transport
67 Lucca wants to protect endpoints that are in production use but that are no longer supported and cannot be patched from network attacks. What should he do to best protect these devices?Install a firewall on the device.Disable all services and open ports on the devices.Place a hardware network security device in front of the devices.Unplug the devices from the network because they cannot be properly secured.
68 Selah's networking team has been asked to identify a technology that will allow them to dynamically change the organization's network by treating the network like code. What type of architecture should she recommend?A network that follows the 5-4-3 ruleA converged networkA software-defined networkA hypervisor-based network
69 Jason knows that protocols using the OSI model rely on encapsulation as data moves from layer to layer. What is added at each layer as data flows up the OSI layers?Information is added to the header.Information is added to the main body of the data.The data is encrypted with a new secret key.A security envelope that provides perfect forward secrecy
70 During a troubleshooting process, the support technician that Alyssa is talking to states that the problem is a layer 3 problem. Which of the following possible issues is not a layer 3 problem?A TTL mismatchAn MTU mismatchAn incorrect ACLA broken network cable
71 During a review of her organization's network, Angela discovered that it was suffering from broadcast storms and that contractors, guests, and organizational administrative staff were on the same network segment. What design change should Angela recommend?Require encryption for all users.Install a firewall at the network border.Enable spanning tree loop detection.Segment the network based on functional requirements.
