Correct Answer:

Test the theory is correct.

Sandbox environments enable all theories to be tested without affecting production environments.

Incorrect Answers:

Establish a plan of action, verify system functionality, and perform a root cause analysis are incorrect.

Establishing a plan of action does not relate to sandbox testing.

Verifying system functionality does not relate to sandbox testing.

Performing a root cause analysis does not relate to sandbox testing.

Correct Answer:

Software inventory is correct.

If software inventory has occurred, the number of instances of software is easily determined.

Incorrect Answers:

PKI, software patching, and Group Policy are incorrect.

Public Key Infrastructure (PKI) is a hierarchy of digital certificates and is not directly related to software licensing.

Software patching cannot be used to determine license compliance.

Group Policy cannot be used to determine license compliance.

Correct Answer:

Bad memory chips is correct.

Failed physical RAM (memory) chips can cause servers to reboot randomly.

Incorrect Answers:

Malware, missing software updates, and missing firmware updates are incorrect.

Although malware could cause reboots, because security logs did not indicate anomalies, bad memory chips is more likely.

Because the problem is recent, the failure to apply software updates is not the most likely cause.

Because the problem is recent, the failure to apply firmware updates is not the most likely cause.

Correct Answer:

Check to see if the system hardware supports 64-bit is correct.

64-bit OSs with a 64-bit data path require a 64-bit architecture. Some older CPUs do not have a 64-bit data path.

Incorrect Answers:

Check to see if the server’s firmware is BIOS or UEFI, check the CPU clock speed, and check the supported virtualization technology are incorrect.

The server firmware would not affect the installation of this new OS.

Since the machine worked with the previous OS, it is unlikely to be a hardware stability issue.

The supported virtualization technology is not necessary to install this operating system.

Correct Answer:

Active/active is correct.

Active/active means the service or application is configured and running on multiple nodes.

Incorrect Answers:

Round-robin, active/passive, and passive/passive are incorrect.

Round-robin is a common DNS technique where multiple similar A records are created but they point to different IP addresses; the first request for a name uses the first A record IP address, the second request uses the second A record IP address, and back and forth.

Active/passive is a configuration where a service or application is active on only a single node at a time.

Passive/passive is not a valid clustering configuration.

Correct Answer:

Maximum PDU load capacity is correct.

You must ensure that power distribution units (PDUs) can accommodate the power draw of the new equipment.

Incorrect Answers:

Maximum BTU load capacity, the number of blades within each enclosure, and the number of server operating systems that will be installed are incorrect.

British thermal units (BTUs) are a measure of heat—in this case, as output from equipment—and load capacity is not related to BTUs.

The number of server blades is not relevant if there is not enough power to turn on the equipment.

The number of server operating systems is not relevant if there is not enough power to turn on the equipment.

Correct Answers:

Wireless access point and VPN appliance are correct.

RADIUS clients such as wireless access points and VPN appliances forward user and device authentication requests to a RADIUS server.

Incorrect Answers:

Smartphone and desktop are incorrect.

Smartphones are supplicants, not RADIUS clients.

Desktops are supplicants, not RADIUS clients.

Correct Answers:

Chassis locks and server room door keypads are correct.

These are physical security controls that can be used to harden, or reduce, the attack surface.

Incorrect Answers:

Software patches and network ACLs are incorrect.

Software patches are not considered physical security.

Network access control lists (ACLs) are not considered physical security.

Correct Answer:

Service level agreement is correct.

A service level agreement (SLA) is a document that, among other things, specifies expected service uptime and response time.

Incorrect Answers:

Memorandum of understanding, disaster recovery plan, and business continuity plan is incorrect.

A memorandum of understanding (MOU) does not cover expected service uptime and response time.

A disaster recovery plan (DRP) does not cover expected service uptime and response time.

A business continuity plan (BCP) does not cover expected service uptime and response time.

Correct Answer:

Mantrap is correct.

A mantrap prevents the inner door from opening until the outer door has closed.

Incorrect Answers:

Dual door, piggybacking, and doortrap are incorrect.

Dual door is not a valid term in this context.

Piggybacking is an invalid term for this physical security control.

Doortrap is an invalid term for this physical security control.
