A branch of a company recently switched to a new ISP. The network engineer was given a new IP range to assign. The ISP assigned 196.26.4.0/26, and the branch gateway router now has the following configurations on the interface that peers to the ISP:

The network engineer observes that all users have lost Internet connectivity. Which of the following describes the issue?

A. The incorrect subnet mask was configured

B. The incorrect gateway was configured

C. The incorrect IP address was configured

D. The incorrect interface was configured

Which of the following is MOST likely to generate significant East-West traffic in a datacenter?

A. A backup of a large video presentation to cloud storage for archival purposes

B. A duplication of a hosted virtual server to another physical server for redundancy

C. A download of navigation data to a portable device for offline access

D. A query from an IoT device to a cloud-hosted server for a firmware update

Which of the following protocols is widely used in large-scale enterprise networks to support complex networks with multiple routers and balance traffic load on multiple links?

A. OSPF

B. RIPv2

C. QoS

D. STP

An office area contains two PoE-enabled WAPs. After the area was remodeled, new cable uplinks were installed in the ceiling above the fluorescent lights. However, after the WAPs were reconnected, users reported slowness and application errors. An intern reviewed the network and discovered a lot of CRC errors. A network engineer reviewed the intern's work and realized UTP cabling was used. Which of the following is the MOST likely cause of the CRC errors?

A. Insufficient power at the antennas

B. PoE and UTP incompatibility

C. Electromagnetic interference

D. Wrong cable pinout

An engineer is using a tool to run an ICMP sweep of a network to find devices that are online. When reviewing the results, the engineer notices a number of workstations that are currently verified as being online are not listed in the report.

The tool was configured to scan using the following information:

Network address: 172.28.16.0

CIDR: /22

The engineer collected the following information from the client workstation:

1.

IP address: 172.28.17.206

2.

Subnet mask: 255.255.252.0

Which of the following MOST likely explains why the tool is failing to detect some workstations?

A. The scanned network range is incorrect.

B. The subnet mask on the client is misconfigured.

C. The workstation has a firewall enabled.

D. The tool is unable to scan remote networks.
