Ace CompTIA Network+ Certification Exam N10-008: Your Gateway to Networking Mastery

Correct : C

To confirm the issue of slow network performance when accessing on-premises email, a network technician shouldcompare the network baselines to the current network status. Here's why:

Reviewing logging levels of network devices(Option A) may provide information about device behavior but won't directly confirm the email performance issue.

Checking audit logs(Option B) is useful for security purposes but doesn't specifically address network performance.

Verifying LDAP accounts(Option D) is relevant for authentication but doesn't directly relate to network performance.

Therefore, the correct answer isC. Compare the network baselines to the current network status

Correct : B

The situation in which an employee knowingly allows someone access to a restricted area without verifying authentication is calledTailgating. Here's why:

Piggybacking(Option A) refers to an unauthorized person following an authorized person into a secure area without their knowledge.

Shoulder surfing(Option C) involves someone observing sensitive information (such as passwords) by looking over another person's shoulder.

Phishing(Option D) is a form of social engineering where attackers deceive individuals into revealing confidential information.

Therefore, the correct answer isB. Tailgating

Correct : B

Since neither of the switches supports MDIX, the systems administrator should use aCrossover cableto connect the two network switches via copper cabling. Here's why:

Straight cable(Option A) is used to connect different types of devices (e.g., switch to computer) and not switches to switches.

Crossover cable(Option B) is specifically designed for connecting similar devices (e.g., switch to switch, switch to hub) without MDIX support.

Patch cable(Option C) is a general term for Ethernet cables and doesn't specify whether it's straight or crossover.

Rollover cable(Option D) is used for console connections to network devices (e.g., connecting to a router or switch console port).

Therefore, the correct answer isB. Crossover

Correct : C

The802.11nstandard is the most suitable option for this scenario. It operates in both the 2.4GHz and 5GHz frequency bands, providing better performance and higher data rates compared to older standards like 802.11b and 802.11g.

802.11n(also known asWi-Fi 4): This standard supports multiple-input and multiple-output (MIMO) technology, which allows for better coverage, increased throughput, and improved reliability. It operates in both the 2.4GHz and 5GHz frequency bands, making it compatible with a wide range of devices. The 5GHz band provides less interference and higher data rates, making it suitable for modern networks.

802.11b: This older standard operates only in the 2.4GHz band and has a maximum data rate of 11 Mbps. It is not recommended for high-performance networks.

802.11g: This standard also operates in the 2.4GHz band and offers a maximum data rate of 54 Mbps. While it is faster than 802.11b, it is still not as efficient as 802.11n.

Correct : C

The servers can communicate with each other but not the internet, indicating local network connectivity is fine. The distribution switch's VLAN and IP configuration are correct, and the engineer can reach the core router, suggesting the issue is not with the switch or the router. The most likely cause is that the servers do not have a default gateway configured, which is necessary for traffic to leave the local network and reach the internet.
