A telecommunications company is laying a new fiber optic cable between two cities. The route passes through areas with high lightning activity and is also at risk of physical tampering. The company wants to ensure the cable is resistant to both electromagnetic interference and physical attacks. Which additional measure is most important?

Use a wireless microwave link instead of fiber.

Bury the cable underground and use armored cable.

Install surge protectors on the fiber cable.

Use a shielded twisted pair cable instead.

A financial firm is installing a new data center link between two buildings 2 km apart. The route crosses a busy highway and an area with frequent lightning storms. The firm requires high bandwidth and resistance to electromagnetic interference. Which transmission medium is most appropriate?

Category 6a shielded twisted pair

A manufacturing company is upgrading its network infrastructure. The plant floor has high electromagnetic interference from heavy machinery, and the network must remain operational during a power outage. Which combination of measures best addresses these concerns?

Use shielded twisted pair cabling and rely on a single generator for backup power.

Use wireless mesh networking and install a large battery backup for the main switch.

Use coaxial cabling and install surge protectors on all outlets.

Use fiber optic cabling and install redundant uninterruptible power supplies (UPS) for critical switches.

A company allows employees to bring their own laptops to work. The security team wants to ensure that only devices with a specific configuration can access the internal network. They also want to automatically quarantine devices that fail a security check. Which solution should they implement?

Network Access Control (NAC) with a post-admission agent that checks for antivirus and patch levels

A VPN that requires two-factor authentication for all remote access

A host-based intrusion prevention system (HIPS) on each laptop

A firewall rule that blocks all traffic from unknown MAC addresses

Why is it important to maintain vendor support and warranty agreements for network infrastructure components?

To ensure timely replacement or repair of failed hardware

To increase the physical security of the data center

To reduce the need for network monitoring

To automatically encrypt all network traffic
