Network Fundamentals

A network engineer is configuring a static IPv4 address for a server residing on a network segment assigned the network ID $172.24.16.0/22$. Which IPv4 address represents a valid usable host address that can be assigned to this server?

Match each Cisco IOS interface status or error counter symptom to its corresponding physical or data-link troubleshooting root cause.

Match each enterprise network infrastructure component on the left with its primary operational function and architectural role on the right.

Match each Cisco IOS interface status or error symptom on the left to its most probable underlying root cause on the right.

A system engineer is configuring a static IPv4 address for a database server located on a segment designated with a network ID of $172.30.100.0$ and a subnet mask of $255.255.254.0$. Company security policy requires that the configured address must be a valid usable host address within the assigned subnet and must also belong to the RFC 1918 private IPv4 address space. Which IPv4 address is a valid host address for this server?

A Layer 2 switch receives an Ethernet frame with a unicast destination MAC address that does not currently exist in its MAC address table. Which two actions does the switch take upon receiving this frame?

An Ethernet frame with a destination MAC address of FFFF.FFFF.FFFF arrives on switch port FastEthernet0/5. The switch MAC address table currently contains no entry for the source MAC address of the frame. Which dual action will the switch perform upon receiving this frame?

An organization is assigned the IPv6 address block $2001:\text{db8}:1111:2000::/52$. A network engineer needs to configure a router interface within a new /64 subnet that has a 12-bit subnet ID extension of $0x\text{A40}$ added to the base /52 prefix. The router interface uses EUI-64 to generate its interface identifier automatically based on its MAC address `0200.4C12.3456`. Which IPv6 Global Unicast Address will be dynamically configured on this interface?

A network technician is configuring static IPv4 addresses for new network monitoring probes on a subnetwork assigned the address block $192.168.50.144/28$. Which of the following IP addresses are valid usable host addresses on this subnet? (Select two.)

An engineer is troubleshooting a degraded Ethernet connection on switch interface `FastEthernet0/8` connected to an end host. The interface output reveals high numbers of `late collisions` and `deferred` frames, while `input errors` remain at zero:

text
FastEthernet0/8 is up, line protocol is up (connected)
Hardware is Fast Ethernet, address is 000c.ce6b.a108
Full-duplex, 100Mb/s, media type is 100BaseTX
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 buffer
3842 late collisions, 1045 deferred, 0 lost carrier

Which TWO physical or data-link conditions are the most probable causes of these output statistics? (Select TWO.)

A network administrator is assigned the IPv6 prefix block `2001:db8:cafe:a000::/56` for a branch office. The administrator must divide this allocation into multiple `/64` subnets for individual client VLANs. Which prefix represents the last `/64` subnet available within this assigned block?

A network architect is designing an enterprise branch network that requires high-speed inter-VLAN routing for internal communication between local subnets, alongside deep packet inspection, stateful traffic monitoring, and intrusion prevention for all internet-bound traffic. Which deployment strategy correctly assigns these operational roles to the appropriate network components to maximize performance and security?

An enterprise infrastructure deployment utilizes a physical server running a bare-metal Type 1 hypervisor. Two virtual machines, VM1 and VM2, reside on this physical host and are attached to the same virtual switch (vSwitch) configured on VLAN 50. The host's physical Network Interface Card (pNIC) connects to an external physical Layer 2 switch port configured for VLAN 50. When VM1 transmits an Ethernet broadcast frame, which statement correctly describes the component roles and frame forwarding behavior across this environment?

Match each transport layer protocol characteristic on the left to its corresponding protocol on the right.

An enterprise network engineer is designing a wireless deployment using a Centralized Wireless LAN Controller (WLC) architecture based on the Split-MAC protocol structure. To ensure low latency for time-sensitive radio frequency operations, certain MAC layer operations must occur on the physical Access Point (AP). Which function is executed directly by the Lightweight Access Point (LAP) hardware rather than being handled by the Centralized WLC?

An enterprise network engineer is implementing a centralized wireless network architecture utilizing Cisco Lightweight Access Points (LAPs) and a centralized Wireless LAN Controller (WLC) operating in Split-MAC mode. Which operational responsibility is handled directly by the Wireless LAN Controller rather than being processed locally by the Lightweight Access Point?

A network engineer is designing a 10 Gbps backbone link between two switches located in separate campus buildings that are 450 meters apart. The campus conduit contains both multi-mode optical fiber (OM2 and OM3) and single-mode optical fiber (OS2). The link must achieve maximum throughput without signal degradation. Which optic transceiver and cabling combination must be selected to fulfill this requirement?

An enterprise network engineer is deploying a centralized wireless architecture using Cisco Lightweight Access Points (LAPs) and a Wireless LAN Controller (WLC) configured for Split-MAC operation. Which function is performed locally by the Lightweight Access Point during normal operation?

A network administrator configures a router interface to automatically generate a global unicast IPv6 address using EUI-64 based on the network prefix $2001:\text{db8}:\text{acad}:1::/64$. Given that the interface burned-in hardware MAC address is $1060.4\text{b}22.3344$, which IPv6 address is dynamically assigned to the interface?

A network administrator is auditing enterprise IP addressing schemas across multiple branch office subnets to ensure full compliance with RFC 1918 private addressing standards. During the audit, the administrator observes four host interface configurations:

- Device A: $10.255.250.1/8$
- Device B: $172.31.255.1/12$
- Device C: $172.32.10.1/16$
- Device D: $192.168.255.1/16$

Which host is configured with a globally routable public IPv4 address rather than a valid RFC 1918 private IPv4 address?
