A network engineer needs to implement a solution where multiple routers share a single virtual IP address for gateway redundancy. Which protocol achieves this?
Answer: VRRP
VRRP (Virtual Router Redundancy Protocol) allows multiple routers to share a virtual IP as a default gateway, with one acting as master and others as backup.
Which type of DNS record is used to map a hostname to an IPv6 address?
Answer: AAAA record
AAAA (quad-A) records map a fully qualified domain name to a 128-bit IPv6 address, while A records map to 32-bit IPv4 addresses.
A company uses BGP to exchange routes with two different ISPs. What type of routing setup does this describe?
Answer: Multi-homed
Multi-homing refers to connecting an organization to two or more separate ISPs for redundancy and load balancing, typically managed with BGP.
Which fiber connector type uses a small form-factor push-pull latch and is common in high-density patch panels?
Answer: LC connector
LC (Lucent Connector) connectors use a small form-factor latch mechanism and are commonly used in SFP transceivers and high-density patch panels.
An administrator wants to monitor traffic between a server and a firewall without interrupting the flow. Which switch feature should be used?
Answer: Port mirroring (SPAN)
Port mirroring (SPAN — Switched Port Analyzer) copies traffic from one or more ports to a designated monitoring port without affecting traffic flow.
Which tunneling protocol encapsulates Layer 2 frames over an IP network and is commonly used to extend VLANs between data centers?
Answer: VXLAN
VXLAN (Virtual Extensible LAN) encapsulates Layer 2 Ethernet frames in UDP packets, enabling VLAN extension across Layer 3 boundaries in data center networks.
A technician needs to confirm that two network devices support the same PoE standard before connecting them. Which tool should be used?
Answer: PoE tester
A PoE tester verifies the power class, voltage, and wattage delivered on a cable to confirm compatibility between PoE-capable switch ports and powered devices.
