A network engineer is configuring the default gateway interface for a enterprise VLAN assigned the IPv4 network block $172.24.128.0/21$. According to network policy, the default gateway must be assigned the highest usable IPv4 address within the subnet. Which IPv4 address must be assigned to the gateway interface?

Match each Virtual Private Network (VPN) technology or protocol component on the left with its corresponding operational characteristic or security capability on the right.

A network administrator is modifying syslog settings on a Cisco IOS router. The router currently has `logging trap errors` configured. The administrator needs to change the configuration so that all events up to severity level 4 (warnings) are forwarded to the remote syslog host, and log messages up to severity level 4 are displayed live during the active SSH session. Which set of commands accomplishes these requirements?

A network administrator is troubleshooting an OSPFv2 neighbor relationship between two directly connected Cisco routers. Command-line interface output indicates that the neighbor relationship is persistently stuck in the ExStart state. Which configuration mismatch is the primary cause of this specific neighbor state condition?

A network administrator is troubleshooting neighbor discovery on a Cisco Catalyst switch connected to a multi-vendor IP phone on interface GigabitEthernet1/0/5. Global LLDP has already been enabled with the `lldp run` command. However, output from `show lldp neighbors` indicates that while the switch successfully processes incoming packets from the IP phone, the IP phone is not receiving any LLDP advertisements from the switch.

Which interface configuration command must be applied under interface GigabitEthernet1/0/5 to resolve this issue and allow the switch to send LLDP frames to the phone?

An administrator executes the command `show ip route` on a Cisco router and observes the following routing table entry:

`O 10.40.0.0/24 [110/50] via 172.16.1.2, 00:15:30, GigabitEthernet0/0`

Which component of the routing table entry is represented by the numerical value 50 inside the brackets?

A network administrator is configuring static routing on router R1 to forward traffic to the destination network $2001:\text{DB8}:\text{CAFE}:5::/64$. The egress interface on R1 is GigabitEthernet0/0/0, which connects directly to router R2. Router R2's connected interface has a global unicast address of $2001:\text{DB8}:\text{LAB}:1::2/64$ and a link-local address of $\text{FE80}::2$. Which command correctly configures a static route on R1 using R2's link-local address as the next hop?

A network host generates its IPv6 link-local address using stateless address autoconfiguration (SLAAC) and the standard IEEE EUI-64 process. If the Ethernet interface has a burned-in MAC address of `0800.27a4.12b3`, what is the resulting IPv6 link-local address assigned to the interface?

A Cisco router receives an IPv4 unicast packet destined for $10.150.45.67$. The router's Routing Information Base (RIB) and Forwarding Information Base (FIB) contain multiple overlapping routes, static entries, and dynamic routing protocol paths. In what exact sequence does the router evaluate routing parameters and process the packet from ingress lookup to physical egress forwarding? Arrange the steps in the correct chronological order from first to last.

A network administrator is setting up a new wireless network using the Cisco Wireless LAN Controller (WLC) web GUI. After defining the WLAN profile name and SSID on the General tab, the administrator needs to configure WPA2 Pre-Shared Key (PSK) authentication for client connectivity. Under which tab and sub-tab within the WLANs > Edit menu is the PSK passphrase field configured?

An infrastructure team is provisioning a new subnet from the IPv4 address block $172.20.96.0/23$ for a server farm that requires support for up to $250$ usable host interfaces. If the team applies the most efficient prefix length that satisfies this requirement, which IPv4 address is the last usable host address in the first subnet created?

Match each Layer 2 discovery protocol characteristic or configuration parameter on the left with its correct operational description or standard on the right.

Refer to the following partial routing table output from a Cisco router:

text
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

Gateway of last resort is 10.4.4.4 to network 0.0.0.0

O 172.16.32.0/20 [110/20] via 10.1.1.1, 00:10:05, GigabitEthernet0/0
D 172.16.35.64/28 [90/307200] via 10.2.2.2, 00:05:12, GigabitEthernet0/1
S 172.16.35.64/26 [1/0] via 10.3.3.3
C 172.16.35.0/24 is directly connected, GigabitEthernet0/2
S* 0.0.0.0/0 [1/0] via 10.4.4.4

The router receives an ingress IPv4 packet with a destination address of 172.16.35.73. Which statements accurately describe the router forwarding decision for this packet? (Select TWO.)

A router learns the destination network $10.20.30.0/24$ dynamically via RIPv2 with a default Administrative Distance of $120$. A network engineer needs to configure a floating static backup route for this network via next-hop IP address $192.168.12.2$. The backup route must only enter the routing table if the primary RIP route fails. Complete the Cisco IOS configuration command to assign an Administrative Distance of $130$ to the floating static route.

A network administrator is configuring an internal host interface and must assign an IP address within the RFC 1918 Class B private address space. Which of the following IP addresses is a valid RFC 1918 private IPv4 address?

An enterprise network engineering team is upgrading a data center fabric to support high-density East-West microsegmentation traffic using a Spine-Leaf architecture. Which of the following statements accurately characterize the topology rules and traffic handling of a standard two-tier Spine-Leaf design? (Select TWO.)

Match each Cisco Lightweight Access Point (AP) operational mode to its precise functional capability and operational behavior within a centralized or branch wireless architecture.

A network engineering team is evaluating configuration management tools to automate Cisco IOS XE switch deployments. The architecture mandates that managed network devices must not require a persistent local management daemon or software agent, and all configuration task execution must be driven from a central control node using native management protocols and human-readable YAML files.

Which of the following operational characteristics correctly describe the selected configuration management tool? (Select TWO.)

A network engineering team is evaluating the operational differences between a traditional distributed architecture and a centralized controller-based network deployment. Which operational characteristic correctly distinguishes the control plane handling in a controller-based network from that of a traditional distributed network?
