While deploying a new switch, you accidentally connect ports 3/12 and 3/18 together, creating a
loop. STP detected it and placed port 3/18 in blocking mode. Why did STP not place port 3/12 in
blocking mode instead?

Which value should be used in the configuration register of a router in order to boot into bootstrap?

Refer to the exhibit.

An enterprise network has an upstream connection to two different ISPs that are using eBGP and
a publicly assigned PI network.
ISP1 is used as the primary provider, while ISP2 is used for backup. Due to packet loss on the link
to ISP1, the network engineers changed the default route on R1 to point to ISP2, but they could
not establish any connection until they changed the default route to point back at ISP1.
Which two are possible root causes of the issue? (Choose two.)

Refer to the Exhibit.

Which two problems does the debug ip ospf event command output from R4 indicate? (Choose
Two)

Refer to the exhibit.

A new link has been provisioned between routers RTA and RTC. After all routing is configured and
connectivity is established, you are facing an application performance issue between network
10.2.0.0/24 and 10.3.0.0/24. When you check the routing table of router RTC, you find out that

packets toward network 10.3.3.0/24 are sent out via the slower path out of the Fa0/0 interface.
What would you do to solve this issue?

Refer to the exhibit.

R4 is unable to establish an EIGRP adjacency with R3, the only other router on the Fa0/0 LAN
segment, although it is able to ping R3. An EIGRP debug on R4 does not provide any clues. What
might be the cause of the problem?

Refer to the exhibit.

The static route to 150.189.131.6 on R3 is intended to serve as the gateway of last resort for the
EIGRP network. However, while R3 installs the gateway of last resort, its EIGRP neighbor R4
does not. What might explain the problem?

Refer to the exhibit.

Which statement would explain why R4 and R3 are unable to build an EIGRP adjacency?

You are the network administrator of a Layer 3 switched network. Users in one VLAN are
complaining that access to the server VLAN is very slow from time to time. Traffic in the local
VLAN works without any issue, and users in other VLANs do not have any complaint to reach the
server VLAN. What is most likely the cause of this issue?

Refer to the exhibit.

RTA and RTB are ABRs for Area 0 and Area 1.
What is the issue with this configuration?
