Question No. 1

Which two statements are true about priority queuing (PQ)? (Choose two.)

ATraffic in the highest priority queue will experience the least amount of jitter and delay compared to traffic in the other queues.

BTraffic in the highest priority queue is only reserved for voice traffic.

CTraffic in lower priority queues can be starved of bandwidth.

DTraffic in all queues are always guaranteed a minimum bandwidth.

Show Answer

Correct Answer: A, C

Priority queuing (PQ) is a queuing method that establishes four interface output queues that serve different priority levels: high, medium, normal, and low. Traffic in the highest priority queue will experience the least amount of jitter and delay compared to traffic in the other queues, because PQ always services the higher-priority queues first. However, this can also cause traffic in lower priority queues to be starved of bandwidth, especially if the highest priority queue is oversubscribed. Traffic in the highest priority queue is not only reserved for voice traffic, but can also include network control and routing traffic. Traffic in all queues are not always guaranteed a minimum bandwidth, because PQ does not provide any bandwidth reservation mechanism.Reference:Quality of Service (QoS) Queues and Queuing Explained,Chapter: Configuring Priority Queueing - Cisco

Question No. 2

Which two statements are true about the Ericsson Router 6000 series? (Choose two.)

AThe Router 6000 uses the same building practice and accessories as the Ericsson Radio System.

BThe Router 6000 can host containerized applications such as firewalls.

CThe Router 6000 is solely built as a radio cell site router.

DThe Router 6000 products range from all-outdoor small site routers to large aggregation routers.

Show Answer

Correct Answer: A, D

Two statements that are true about the Ericsson Router 6000 series are:

The Router 6000 uses the same building practice and accessories as the Ericsson Radio System. The Ericsson Radio System is a modular and scalable radio access network solution that supports multiple standards, bands, and layers. The Router 6000 series is fully integrated into the Ericsson Radio System, using the same building practice and accessories such as mounting kits, cables, power supplies, etc.This simplifies installation, operation, and maintenance of both radio and transport equipment78.

The Router 6000 products range from all-outdoor small site routers to large aggregation routers. The Router 6000 series consists of three main products: the Router 6672 for access, the Router 6675 for pre-aggregation, and the Router 6274 for metro aggregation. The Router 6672 is an all-outdoor small cell site router with high-capacity and low-power consumption. The Router 6675 is a combined access and E-RAN switch with hardware-accelerated IPSec and high-accuracy internal clock.The Router 6274 is a high-capacity metro aggregation router with SDN functionality and flexible interface options78.

Question No. 3

Which two statements are correct for LDP? (Choose two.)

ALSRs send UDP hello messages for neighbor discovery.

BLSRs send ICMP hello messages for neighbor discovery

CLSRs use TCP to negotiate LDP session parameters.

DLSRs use UDP for session establishment.

Show Answer

Correct Answer: A, C

Two statements that are correct for LDP are:

LSRs send UDP hello messages for neighbor discovery. LDP is a protocol that distributes labels for MPLS forwarding along the shortest path calculated by an IGP. LDP uses two types of messages: discovery messages and session messages. Discovery messages are used to discover and maintain adjacency with other LSRs that support LDP.Discovery messages are sent as UDP datagrams to the well-known multicast address 224.0.0.2 (all routers on this subnet) on port 64634.

LSRs use TCP to negotiate LDP session parameters. Session messages are used to establish, maintain, and terminate LDP sessions between LSRs. Session messages are also used to exchange label mappings, notification messages, and keepalive messages.Session messages are sent as TCP segments to port 64634.

Question No. 4

Which network is reserved as a private network according to RFC1918?

A172.16.1.0/9

B10.254.1.0/24

C193.168.1.0/24

D172.15.1.0/24

Show Answer

Correct Answer: B

According to RFC1918, there are three network blocks reserved as private networks that are not allocated to any specific organization and are not routable on the public Internet. These are:

10.0.0.0/8 (10.0.0.0 - 10.255.255.255)

172.16.0.0/12 (172.16.0.0 - 172.31.255.255)

192.168.0.0/16 (192.168.0.0 - 192.168.255.255)

Out of these, only option B (10.254.1.0/24) falls within one of the private network blocks (10.0.0.0/8). Option A (172.16.1.0/9) is not valid because it exceeds the /12 prefix length of the private network block (172.16.0.0/12). Option C (193.168.1.0/24) is not valid because it does not belong to any of the private network blocks, and is actually assigned to RIPE NCC as a public network block . Option D (172.15.1.0/24) is also not valid because it does not belong to any of the private network blocks, and is actually assigned to ARIN as a public network block .Reference:RFC 1918: Address Allocation for Private Internets,Private network - Wikipedia, [RIPE NCC IPv4 Address Space Chart], [ARIN WHOIS Database Search]

Question No. 5

What is an important difference between OSPF and IS-IS?

AOSPF runs directly on IP, while IS-IS runs directly on Ethernet.

BOSPF is a link state protocol, while IS-IS is a distance vector protocol.

COSPF runs directly on Ethernet, while IS-IS runs directly on IP.

DOSPF is a distance vector protocol, while IS-IS is a link state protocol.

Show Answer

Correct Answer: A

OSPF runs directly on IP, while IS-IS runs directly on Ethernet. This means that OSPF uses IP addresses to identify routers and links, while IS-IS uses MAC addresses or other link-layer identifiers. OSPF also requires an IP header for each packet, while IS-IS does not. Both OSPF and IS-IS are link state protocols, which means that they flood information about the network topology to all routers in the same area or domain.Reference:Ericsson IP Networking - Routing Protocols,Ericsson Router 6000 Series - Ericsson
