Correct Answer:

Incremental is correct.

Incremental backups copy only changed data from the last full or incremental backup.

Incorrect Answers:

Full, differential, and normal are incorrect.

Full backups take the longest because they back up all data.

Differential backups take longer than incremental because they copy all changed data since the last full backup.

The term normal backup usually refers to a full backup.

Correct Answer:

MAC address is correct.

MAC addresses are hardware addresses that map to Layer 2 of the OSI model.

Incorrect Answers:

Port number, IP address, and session identifier are incorrect.

Port numbers map to Layer 4 of the OSI model.

IP addresses map to Layer 3 of the OSI model.

Session identifiers do not apply in this context.

Correct Answer:

The Linux VM is the guest of the host Hyper-V hypervisor is correct.

The Hyper-V hypervisor is the host under which the Linux VM is a guest.

Incorrect Answers:

The Linux VM is the host of the guest Hyper-V hypervisor, the Linux VM is the virtual switch for the Hyper-V hypervisor, and the Linux VM allocates resources for the Hyper-V hypervisor are incorrect.

The Linux VM is not a host to the Hyper-V hypervisor.

The Hyper-V hypervisor, as a host, would allocate resources for its guests such as the Hyper-V hypervisor.

The Hyper-V hypervisor, as a host, would allocate connectivity to a virtual switch for its guests such as the Hyper-V hypervisor.

Correct Answer:

Tower is correct.

Tower servers take up the most space.

Incorrect Answers:

Blade, physical, and virtual are incorrect.

Blades take up the least amount of space.

Physical is not a server form factor.

Virtual is not a server form factor.

Correct Answer:

UDP 123 is correct.

Network Time Protocol (NTP) uses UDP port 123.

Incorrect Answers:

TCP 123, TCP 161, and UDP 161 are incorrect.

NTP does not use TCP port 123.

NTP does not use TCP port 161.

NTP does not use UDP port 123.

Correct Answer:

Modify is correct.

The NTFS modify permission will allow Peter to delete files.

Incorrect Answers:

Rm, write, and remove are incorrect.

There is no NTFS rm permission.

The NTFS write permission does not allow file deletion.

There is no NTFS remove permission.

Correct Answer:

Crossover is correct.

A crossover cable reverses receive and transmit at both ends.

Incorrect Answers:

Straight-through, rollover, UTP and are incorrect.

Straight-through cables, as the name implies, do not reverse any wires at either end.

Rollover cables are used to connect to network equipment locally for administration.

Unshielded twisted pair (UTP) is a general type of cable consisting of copper wires.

Correct Answer:

172.16.255.1 is correct.

IPv4 reserved addresses fall in the range of 10.0.0.0–10.255.255.255, 172.16.0.0–172.31.255.255, and 192.168.0.0–192.168.255.255.

Incorrect Answers:

17.46.5.33, 192.168.5.257, and 10.255.255.255 are incorrect.

17.46.5.33 is not a reserved address.

192.168.5.257 is invalid; 255 is the maximum value for an octet.

10.255.255.255 is a broadcast address and cannot be assigned to a host.

Correct Answer:

Baseline is correct.

Baselines of normal server activity can be used to identify abnormal activity.

Incorrect Answers:

Software inventory, hardware inventory, and normal incorrect.

A software inventory cannot detect abnormal activity as easily as baselines can.

A hardware inventory cannot detect abnormal activity as easily as baselines can.

There is no such thing as normal documentation in this context.

Correct Answer:

Grandfather-father-son is correct.

Grandfather-father-son is the most common backup media rotation type where backup media gets reused. The common strategy is to use three backup sets—daily, weekly, and monthly—where media is rotated on a schedule.

Incorrect Answers:

Tower of Hanoi, incremental rotation, and decremental rotation are incorrect.

Tower of Hanoi is a valid backup media rotation strategy; however, it is not as common as grandfather-father-son.

Incremental rotation is a valid backup media rotation strategy; however, it is not as common as grandfather-father-son.

Decremental rotation is not a backup rotation strategy.
