QUESTION: 145

A server administrator is installing a new server that uses 40G0 network connectivity. The administrator needs to find the proper cables to connect the server to the switch.
Which of the following connectors should the administrator use?

SFP+
GBIC
SFP
QSFP+

Answer(s): D

Explanation:

QSFP+ is a type of connector that should be used to connect a server to a switch that uses 40G network connectivity. QSFP+ (Quad Small Form-factor Pluggable Plus) is a compact, hot-pluggable transceiver module that supports data rates up to 40 Gbps. QSFP+ modules can be used for various network protocols and media types, such as Ethernet, Fibre Channel, InfiniBand, or optical fiber. QSFP+ modules have a 38-pin edge connector and can be inserted into a QSFP+ port on a switch or a server. SFP+ (Small Form-factor Pluggable Plus) is a type of connector that supports data rates up to 10 Gbps, but not 40 Gbps. SFP+ modules have a 20-pin edge connector and can be inserted into an SFP+ port on a switch or a server. GBIC (Gigabit Interface Converter) is an older type of connector that supports data rates up to 1 Gbps, but not 40 Gbps. GBIC modules have an SC duplex connector and can be inserted into a GBIC port on a switch or a server. SFP (Small Form-factor Pluggable) is another older type of connector that supports data rates up to 1 Gbps or 4 Gbps, but not 40 Gbps. SFP modules have an LC duplex connector and can be inserted into an SFP port on a switch or a server.

QUESTION: 146

Due to a recent application migration, a company's current storage solution does not meet the necessary requirements tor hosting data without impacting performance when the data is accessed in real time by multiple users.
Which of the following is the BEST solution for this Issue?

Install local external hard drives for affected users.
Add extra memory to the server where data is stored.
Compress the data to increase available space.
Deploy a new Fibre Channel SAN solution.

Answer(s): D

Explanation:

A Fibre Channel SAN solution is a type of storage area network (SAN) that uses high-speed optical fiber cables to connect servers and storage devices. A SAN allows for hosting data without impacting performance when the data is accessed in real time by multiple users, as it provides fast data transfer rates, low latency, high availability, and scalability. A local external hard drive (A) would not be suitable for multiple users, as it would limit the accessibility and security of the data. Adding extra memory to the server (B) would not solve the problem of data access performance, as it would not increase the bandwidth or reduce the congestion of the network. Compressing the data © would not improve the performance either, as it would add extra overhead and complexity to the data processing and retrieval.

QUESTION: 147

Users ate experiencing issues when trying to access resources on multiple servers. The servers are virtual and run on an ESX server. A systems administrator is investigating but is unable to connect to any of the virtual servers.
When the administrator connects to the host, a purple screen with while letters appears.
Which of the following troubleshooting steps should the administrator perform FIRST?

Check the power supplies
Review the log files.
Reinstall the ESX server.
Reseat the processors.

Answer(s): B

Explanation:

A purple screen with white letters on an ESX server indicates a kernel panic, which is a fatal error that causes the system to crash and stop functioning. The first troubleshooting step that an administrator should perform is to review the log files, which may contain information about the cause of the error, such as hardware failures, software bugs, or configuration issues. Checking the power supplies (A) may not be relevant, as the system is still displaying a screen. Reinstalling the ESX server © or reseating the processors (D) are drastic measures that may result in data loss or further damage, and should only be attempted after ruling out other possible causes.

QUESTION: 148

Hosting data in different regional locations but not moving it for long periods of time describes:

a cold site.
data at rest.
on-site retention.
off-site storage.

Answer(s): B

Explanation:

Data at rest refers to data that is stored in a persistent state on any device or media, such as hard drives, tapes, or cloud storage. Data at rest does not move for long periods of time unless it is accessed or modified by authorized users or applications. A cold site (A) is a backup location that has minimal or no equipment and resources to resume business operations in case of a disaster. On-site retention © is a policy of keeping backup data on premises for a certain period of time before transferring it to an off-site location. Off-site storage (D) is a method of storing backup data in a remote location that is physically or logically separated from the primary site.
