Question 1
Multiple choice

Factors causing the ODN link loss include: (Select All that Apply)

A.

Fiber transmission loss

B.

Optical splitter loss

C.

Extra line loss, about 3 dB in general

D.

Splicing and cord end loss

E.

Connectors and flange loss

Question 2
Single choice

The routing table of a router contains the following two entries:

Destination/Mask | Protocol | Pre | Cost | Nexthop | Interface

9.0.0.0/8 | OSPF | 10 | 50 | 1.1.1.1 | Serial0

9.1.0.0/16 | RIP | 100 | 5 | 2.2.2.2 | Ethernet0

If the router needs to forward packets with the destination address of 9.1.4.5, which statement is correct?

A.

The router selects the second route, because the metric of RIP is smaller.

B.

The router selects the second route, because the outbound interface is Ethernet0, which is faster.

C.

The router selects the first route, because the priority of OSPF is higher.

D.

The router selects the second route, because this route matches the destination address 9.1.4.5 more accurately.

Question 3
Single choice

A school uses the POL networking and has only one campus. During VLAN design, VLANs are divided by service type and services are identified by a single VLAN tag.
In this case, which VLAN attribute should be used?

A.

Common

B.

QinQ

C.

Sub

D.

Stacking

Question 4
Single choice

Which of the following statements about static routes is correct?

A.

Static routes are manually added to a routing table but are not dynamically updated by a routing protocol.

B.

When the network topology changes, static routes need to be recalculated.

C.

Static routes are learned from another routing protocol and imported to a local routing table.

D.

Static routes have been set before a router is delivered to the market.

Question 5
Single choice

To facilitate subsequent management, a university wants to use double-tagged VLANs. The inner VLAN tag is used to identify users, and the outer VLAN tag is used to identify services.

Which VLAN attribute should be used?

A.

Standard type, common attribute

B.

Smart type, stacking attribute

C.

Standard type, QinQ attribute

D.

Smart type, common attribute

Question 6
Single choice

If a PON system is considered as a black box, the external interfaces of OLTs and ONU are mainly Ethernet interfaces, and GEM encapsulation and decapsulation are performed inside the PON system.

A.

TRUE

B.

FALSE

Question 7
Single choice

Which of the following indicator status indicates that the MA5600T/MA5680T control board is running properly?

A.

Green is on and is off repeatedly.

B.

Steady green.

C.

Green 0.5s on and 0.5s off repeatedly.

D.

Green 0.25s on and 0.25s off repeatedly.

Question 8
Single choice

The Ethernet technology is a widely used technology. According to different transmission rates, the Ethernet technology is classified into 10 Mbit/s, 100 Mbit/s, and 1000 Mbit/s. The 10 Mbit/s and 100 Mbit/s
Ethernet transmission media are twisted pairs, but the 1000 Mbit/s Ethernet is too fast and requires optical fibers as the transmission media.

A.

TRUE

B.

FALSE

Question 9
Single choice

The MA5800 supports upstream transmission through the control board or upstream board, and supports 10 GE/GE upstream transmission. The upstream port supports 10 GE upstream transmission by default.
You can run the speed command to set the upstream port. To prevent the communication failure with the upper-layer device, the upstream port rate must be the same as the port rate of the interconnected device.

A.

TRUE

B.

FALSE

Question 10
Single choice

Which of the following statements about the test of the mean optical transmit power of an optical interface is incorrect?

A.

Repeat the preceding steps to check whether the maximum and minimum values of the mean optical transmit power meet the technical requirements.

B.

The optical power meter is calibrated.

C.

The fiber connector and the optical connector on the panel of the optical interface board are clean and connected properly.

D.

Connect one end of the test pigtail to the Rx port on the optical interface board, and connect the other end of the pigtail to the optical power meter.
