Answer : B

An 802.11ac wireless bridge is the most practical solution to connect two nearby buildings without trenching or laying physical cable. It provides high-speed, point-to-point connectivity using directional antennas.

A . Multimode fiber is effective but expensive and typically limited to 500 meters or less.

C . Cat 6 copper is only rated for up to 100 meters --- not viable for a street-wide distance.

D . Loopback adapter is a troubleshooting tool, not for network extension.

Answer : D

Private VLANs (PVLANs) are used to segment devices on the same subnet and switch so they cannot communicate with each other, while still accessing a shared resource like a router or gateway. This is often used in shared hosting or DMZ environments.

A . ACLs (Access Control Lists) control traffic between networks, not within the same VLAN.

B . Trunking carries multiple VLANs between switches but does not isolate devices.

C . Port security limits MAC addresses per port but doesn't isolate communication between ports.

Answer : A

A hot site is a fully operational backup facility with hardware, network, and data synchronization already in place. It allows for immediate failover in the event of a disaster, minimizing downtime.

B . DCI (Data Center Interconnect) connects data centers but doesn't guarantee availability unless built redundantly.

C . Direct Connect refers to a private link to cloud providers, not disaster recovery.

D . Active-passive can help with failover but may involve delay unless combined with hot site principles.

Answer : B

To support at least 260 hosts, you need at least 512 total IP addresses (accounting for network/broadcast overhead).

/23 (255.255.254.0) gives 510 usable IPs, ideal for 260 devices with minimal waste.

/24 (255.255.255.0) gives only 254 usable --- not enough.

/22 (1022 usable) and /21 (2046 usable) would work but result in significant address waste.

Answer : B

TLS (Transport Layer Security) is the protocol that provides encryption in transit for HTTPS. It ensures data is encrypted between the client (browser) and the web server, protecting it from interception or tampering.

A . SSH is used for secure terminal access, not HTTPS.

C . SCADA refers to control systems, not encryption protocols.

D . RADIUS is an authentication protocol, not for encrypting HTTPS traffic.
