A network administrator is downloading a large patch that will be uploaded to several enterprise switches simultaneously during the day’s upgrade cycle.
Which of the following should the administrator do to help ensure the upgrade process will be less likely to cause problems with the switches?
- A . Confirm the patch’s MD5 hash prior to the upgrade
- B . Schedule the switches to reboot after an appropriate amount of time.
- C . Download each switch’s current configuration before the upgrade
- D . Utilize FTP rather than TFTP to upload the patch
A
Explanation:
The network administrator should confirm the patch’s MD5 hash prior to the upgrade to help ensure the upgrade process will be less likely to cause problems with the switches. MD5 (Message Digest 5) is a cryptographic hash function that produces a 128-bit hash value for any given input. It can be used to verify the integrity and authenticity of a file by comparing its hash value with a known or expected value. If the hash values match, it means that the file has not been corrupted or tampered with during transmission or storage. If the hash values do not match, it means that the file may be damaged or malicious and should not be used for the upgrade.

Users ate moving back into an office that had been vacant for awhile. Ten workstations are hooked up in the office, but one workstation cannot obtain a link with (he switch. A network engineer checks the documentation and cable labeling, and everything is hooked up as expected. The engineer moves the connection lo a different switchport. but a link still cannot be obtained. When the engineer puts a tone generator on the infrastructure cable, no tone is heard at the far end.
Which of the following issues is the engineer MOST likely trying to find?
- A . A bad switchport
- B . A break in the cable
- C . A cable short
- D . Cable interference
B
Explanation:
A break in the cable means that there is no electrical continuity between the two ends of the cable, which prevents the signal from reaching the switch. A tone generator is a device that sends an audible signal through the cable, and if no tone is heard at the far end, it indicates a break in the cable.
A corporation has a critical system that would cause unrecoverable damage to the brand if it was taken offline.
Which of the following disaster recovery solutions should the corporation implement?
- A . Full backups
- B . Load balancing
- C . Hot site
- D . Snapshots
C
Explanation:
A hot site is the disaster recovery solution that the corporation should implement for its critical system that would cause unrecoverable damage to the brand if it was taken offline. A hot site is a fully operational backup site that can take over the primary site’s functions in case of a disaster or disruption. A hot site has all the necessary hardware, software, data, network connections, and personnel to resume normal operations with minimal downtime. A hot site is suitable for systems that require high availability and cannot afford any data loss or interruption.

A network administrator is investigating a network connectivity issue. The administrator runs a command to view the status of the network cards.
The administrator receives the following output:
Which of the following should the administrator troubleshoot based on the output?
- A . Physical layer components
- B . VLAN tagging configuration
- C . Buffers on the card filling up
- D . TCP/IP address settings
A
Explanation:
Based on the provided output, the administrator should troubleshoot physical layer components.
Here’s why:
The output shows statistics related to received packets, errors, dropped packets, overruns, and frame.
These statistics are related to the physical layer of network communication.
VLAN tagging, buffers, and TCP/IP address settings are not directly reflected in this output.
Therefore, the correct answer is A. Physical layer components
A network administrator discovers that users in an adjacent building are connecting to the company’s guest wireless network to download inappropriate material.
Which of the following can the administrator do to MOST easily mitigate this issue?
- A . Reduce the wireless power levels
- B . Adjust the wireless channels
- C . Enable wireless client isolation
- D . Enable wireless port security
A
Explanation:
Reducing the wireless power levels can limit the range of the guest wireless network and prevent users in an adjacent building from connecting to it. Adjusting the wireless channels or enabling wireless client isolation will not affect the signal strength or coverage of the guest network. Enabling wireless port security will not work on a guest network that does not use authentication or MAC address filtering.

A senior administrator has been directed to incorporate AAA services within a domain environment for regulatory compliance purposes.
Which of the following standards will enable the use of an AAA server in a domain environment?
- A . 802.1Q
- B . 802.1X
- C . 802.3bt
- D . 802.11h
B
Explanation:
Which of the following transceiver types can support up to 40Gbps?
- A . SFP+
- B . QSFP+
- C . QSFP
- D . SFP
B
Explanation:
QSFP+ is a transceiver type that can support up to 40Gbps. It stands for Quad Small Form-factor Pluggable Plus and uses four lanes of data to achieve high-speed transmission. It is commonly used for data center and high-performance computing applications.

A user is having trouble uploading files to a server. However, other users in the department are not experiencing this issue. The network administrator checks the access switch and sees multiple CRC errors on that user’s switchport.
Which of the following should the network administrator do first?
- A . Replace the uplink cable for the access switch.
- B . Replace the user’s network cable.
- C . Replace the NIC for the user’s PC.
- D . Replace the access switch.
B
Explanation:
When a network administrator observes CRC errors on a specific switchport associated with one user, the first troubleshooting step recommended is to replace the user’s network cable. CRC errors are often indicative of physical layer issues such as noise, interference, or damaged cables. By replacing the network cable, the administrator can potentially resolve these errors without more drastic measures like replacing hardware components (NIC, switch, or uplink cables), which could be more costly and less effective as initial steps. This approach minimizes downtime and is a cost-effective first step in the troubleshooting process.
Which of the following technologies allows traffic to be sent through two different ISPs to increase performance?
- A . Fault tolerance
- B . Quality of service
- C . Load balancing
- D . Port aggregation
C
Explanation:
Load balancing is a technology that allows traffic to be sent through two different ISPs to increase performance. Load balancing is a process of distributing network traffic across multiple servers or links to optimize resource utilization, throughput, latency, and reliability. Load balancing can be implemented at different layers of the OSI model, such as layer 4 (transport) or layer 7 (application). Load balancing can also be used for outbound traffic by using multiple ISPs and routing protocols such as BGP (Border Gateway Protocol) to select the best path for each packet.
