Network Fundamentals

A network engineer deploys lightweight access points (LAPs) at a remote branch office connected over a WAN to a centralized Wireless LAN Controller (WLC). During a WAN outage, clients connected to APs in Local mode lose network connectivity, while clients connected to APs configured in FlexConnect mode with local switching retain local network access. Which operational characteristic of Local mode APs accounts for this behavior?

A system architect is migrating a software-defined branch office infrastructure from hosted hypervisors (Type 2) to bare-metal hypervisors (Type 1). During performance baseline testing, the team observes significantly reduced network frame handling latency and lower host CPU overhead on the bare-metal architecture. Which architectural characteristic of Type 1 hypervisors accounts for this performance improvement?

Match each IPv6 address type on the left with its corresponding reserved prefix range on the right. Which pairs correctly match each IPv6 address scope to its standard IPv6 prefix?

An administrator is auditing a dual-stack network segment where hosts use Stateless Address Autoconfiguration (SLAAC) with EUI-64 to derive their 64-bit interface identifiers. A workstation with the Burned-In MAC address `34-E6-D7-89-0A-1B` sends a Router Solicitation message. What is the correctly formatted IPv6 Link-Local address generated by this interface?

A network administrator is allocated the IPv6 prefix block $2001:\text{db8}:5678:\text{a000}::/52$ for an enterprise deployment. Which two IPv6 addresses belong to valid subnets within this assigned prefix block? (Select two.)

A network administrator is designing the transport transport layer profile for an enterprise network management system. The system requires a stateless transport mechanism for high-frequency, low-latency telemetry collection where occasional packet loss is tolerable, alongside a stateful transport mechanism for secure interactive router configuration sessions. Which two characteristics accurately describe the transport layer protocols selected for these respective roles? (Select two.)

Match each virtualization component on the left with its corresponding primary function or definition on the right.

Match each network topology architecture model or functional layer on the left to its corresponding design trait and operational responsibility on the right.

A network administrator is reviewing bandwidth efficiency for application traffic traversing a low-bandwidth WAN link. Which statement accurately compares the baseline header size overhead between Transmission Control Protocol (TCP) and User Datagram Protocol (UDP)?

A network engineer is deploying new infrastructure across a multi-site enterprise network. Match each network component on the left to its primary operational function on the right.

A network engineer is configuring a Cisco router interface with the command `ipv6 address 2001:db8:cafe:100::/64 eui-64`. The burn-in MAC address of the interface is `1866.DA12.3456`. Based on the IEEE EUI-64 process, which IPv6 global unicast address will be dynamically assigned to this interface?

A network administrator is analyzing Cisco IOS switch interface outputs to resolve network degradation. Match each interface status combination or error counter condition on the left to its corresponding primary root cause on the right.

A network architect is implementing Variable Length Subnet Masking (VLSM) for an enterprise branch using the assigned summary prefix $172.20.0.0/19$. Four subnets must be allocated sequentially from the lowest available IP address of the block to support the following minimum host requirements:

- Location A: 1,000 usable hosts
- Location B: 480 usable hosts
- Location C: 250 usable hosts
- Location D: 120 usable hosts

Each subnet must be sized using the smallest possible prefix length to satisfy its host requirement. After completing these four allocations in order (Location A, then B, then C, then D), what is the maximum number of usable host IPv4 addresses that can be accommodated in the single largest contiguous unallocated subnet block remaining in the $172.20.0.0/19$ summary range?

A network technician is reviewing the physical and logical layout of a small branch office network that uses a 2-Tier (Collapsed Core) campus topology. Which two statements accurately describe key characteristics of this topology architecture? (Select TWO.)

A Cisco Catalyst switch contains the following entry in its MAC address table for VLAN 10:

A network technician disconnects the host with MAC address 000a.1111.2222 from port GigabitEthernet0/1 and reconnects it to port GigabitEthernet0/3. The host immediately transmits an Ethernet frame destined for MAC address 000b.3333.4444 into port GigabitEthernet0/3 on VLAN 10. How will the switch handle MAC address learning and frame forwarding for this ingress traffic?

A remote branch office requires a dedicated network device to route traffic between local department subnets, isolate broadcast domains, and establish an encrypted site-to-site IPsec tunnel to the main corporate data center. Which network component is designed to perform these combined operational functions?

In a standard two-tier Spine-Leaf data center architecture, to which switches does every leaf switch directly connect?

A network administrator executes the `show interfaces GigabitEthernet0/2` command on a Cisco IOS switch to investigate frame loss on a point-to-point connection. The command output displays the following status:

text
GigabitEthernet0/2 is up, line protocol is up
Full-duplex, 1000Mb/s, media type is 10/100/1000BaseTX
14205 input errors, 14205 CRC, 0 frame, 0 overrun, 0 ignored
0 output errors, 0 collisions, 0 interface resets

Based on the CLI output, which condition is the most likely cause of the observed interface statistics?

A network administrator is selecting a transport layer protocol for a real-time voice streaming service where low transmission latency is required and dropped packets should not be retransmitted. Which characteristic of User Datagram Protocol (UDP) makes it better suited than Transmission Control Protocol (TCP) for this application?

Match each network application operational requirement or protocol scenario on the left with its corresponding transport layer protocol implementation characteristic on the right.
