How do TCP and UDP differ in the way that they establish a connection between two endpoints?
The correct answer is A. Option A: TCP uses the three-way handshake, and UDP does not guarantee message delivery.
Which 802.11 frame type is Association Response?

In which way does a spine-and-leaf architecture allow for scalability in a network when additional access ports are required?
The correct answer is C. Option C: A leaf switch can be added with connections to every spine switch. This option scales automatically to match demand.
What identifies the functionality of virtual machines?
The correct answer is C. Option C: The hypervisor virtualizes physical components including CPU, memory, and storage.
Which command automatically generates an IPv6 address from a specified IPv6 prefix and MAC address of an interface?
The correct answer is B. Option B: ipv6 address 2001:DB8:5:112::/64 eui-64
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead. IPv6 uses 128-bit addresses and relies on Neighbor Discovery rather than ARP.
When configuring IPv6 on an interface, which two IPv6 multicast groups are joined? (Choose two.)
The correct answer is D, E. Option D: FF02::1 Option E: FF02::2
What is the default behavior of a Layer 2 switch when a frame with an unknown destination MAC address is received?
The correct answer is C. Option C: The Layer 2 switch floods packets to all ports except the receiving port in the given VLAN.
Explanation
A VLAN creates a separate Layer 2 broadcast domain on switched infrastructure.
An engineer must configure a /30 subnet between two routes. Which usable IP address and subnet mask combination meets this criteria?
The correct answer is D. Option D: interface e0/0 description to XX-AXXX:XXXXX ip address 209.165.201.2 225.255.255.252
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead.
Which network allows devices to communicate without the need to access the Internet?
The correct answer is B. Option B: 172.28.0.0/16 This option keeps traffic private / properly secured as required.
Refer to the exhibit. Which statement explains the configuration error message that is received?
The correct answer is D. Option D: It is a broadcast IP address.
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead.
Which IPv6 address type provides communication between subnets and cannot route on the Internet?
The correct answer is B. Option B: unique local
Which IPv6 address block sends packets to a group address rather than a single address?
The correct answer is D. Option D: FF00::/8
What are two reasons that cause late collisions to increment on an Ethernet interface? (Choose two.)
The correct answer is B, E. Option B: when one side of the connection is configured for half-duplex Option E: when the cable length limits are exceeded
What is a benefit of using a Cisco Wireless LAN Controller?
The correct answer is A. Option A: It eliminates the need to configure each access point individually.
Explanation
NAT translates addresses between network domains, commonly conserving public IPv4 addresses.
Which action is taken by switch port enabled for PoE power classification override?
The correct answer is A. Option A: If a monitored port exceeds the maximum administrative value for power, the port is shutdown and err-disabled.
What occurs to frames during the process of frame flooding?
The correct answer is C. Option C: Frames are sent to every port on the switch in the same VLAN except from the originating port.
Explanation
A VLAN creates a separate Layer 2 broadcast domain on switched infrastructure. NAT translates addresses between network domains, commonly conserving public IPv4 addresses.
Which function does the range of private IPv4 addresses perform?
The correct answer is A. Option A: allows multiple companies to each use the same addresses without conflicts
