PK0-005 Project Management Concepts Practice Question
This PK0-005 practice question tests your understanding of project management concepts. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Exhibit
Refer to the exhibit.
Network configuration:
interface GigabitEthernet0/1
description Link to Core
ip address 10.10.10.1 255.255.255.0
duplex full
speed 1000
no shutdown

interface GigabitEthernet0/2
description Link to Backup
ip address 10.10.20.1 255.255.255.0
duplex full
speed 1000
no shutdown

The project manager is reviewing the network configuration for a new branch office. The configuration shows two interfaces. Which of the following is a project management concern regarding this configuration?

A
The IP addresses are on the same subnet, causing a conflict.
Why wrong: They are on different subnets: .0 and .20.
B
There is no redundancy protocol for default gateway failover.
Without HSRP/VRRP, if one link fails, traffic may be lost.
C
The speed and duplex settings are mismatched.
Why wrong: Both are set to 1000 full, so no mismatch.
D
The description is misspelled.
Why wrong: Misspelling does not affect functionality.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
There is no redundancy protocol for default gateway failover.
The correct answer is B because the network configuration shows two interfaces, likely representing a dual-homed or multi-homed setup. Without a redundancy protocol such as HSRP, VRRP, or GLBP, there is no automatic failover for the default gateway, meaning a single link or router failure would cause a loss of connectivity for the branch office. This is a project management concern because it impacts network availability and business continuity, which should be addressed in the project requirements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may focus on technical misconfigurations like IP conflicts or speed/duplex mismatches, but the question asks for a project management concern, which is about ensuring availability and meeting business requirements, not just fixing low-level technical errors.
Detailed technical explanation
How to think about this question
HSRP (Hot Standby Router Protocol) uses a virtual IP address and MAC address to provide default gateway redundancy; if the active router fails, the standby router takes over transparently to hosts. Without such a protocol, clients configured with a single default gateway IP will experience an outage until the gateway is manually changed or the link is restored. In a branch office with two WAN links, using policy-based routing or dynamic routing protocols like OSPF can also provide failover, but the absence of a first-hop redundancy protocol is a common oversight in network designs.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
