更多"[判断题]ZXUN SSS扩容都是在线扩容，按形式可以分为硬件扩容和软"的相关试题:
[多选题]SSS进行单板扩容操作,如果单板无法正常上电,则需要检查的内容包括
A.单板硬件故障
B.单板IPMC等版本信息不匹配
C.单板物理类型不匹配
D.单板配置错误
[判断题]SSS扩容后需要注意自身的接口变化，包括Provision接口变化，所以在扩容后需要联系BOSS进行业务发放测试。
After SSS expansion, you should pay attention to interface changes of the SSS, including the change of the Provision interface. Therefore, after SSS expansion, you need to contact the BOSS system to perform service distribution tests.
A.正确
B.错误
[多选题]SSS进行DIAMETER链路扩容,涉及到的内容包括
A.新增IP地址或者端口
B.新增SCTP链路
C.新增DIAMETER链路
D.进行DIAMETER路由配置
[多选题]SSS扩容过程中容灾配合操作描述正确的有（ ）。
Which of the following statements are correct about disaster-tolerance operations during SSS expansion? ( )
A.一般情况下扩容不推荐容灾方式扩容，因为已有的容量已经达到系统极限，容灾方式对另一侧的系统是个考验
Usually, it is not recommended t apply the disaster-tolerance mode in expansion. This is because the existing capacity has reached system limits, so the disaster-tolerance mode is a test upon the system on the other side.
B.扩容过程中在数据配置完成后重启单板过程中会发生容灾倒换，部分用户由于刷新注册到期后无法进行正常刷新会容灾到备用局点
During the expansion process, disaster-tolerance switchover will occur when the board is restarted after data configurations are completed. When refresh registration of some users is expired, these users cannot be refreshed normally, so they will be switched to the standby office for disaster-tolerance.
C.业务测试验证前，需要将邻接网元的容灾状态倒回，以让用户回到扩容的SSS上进行注册
Before service test verification, we need to switch back the disaster-tolerance status of adjacent NEs, so that users are registered on the disaster-tolerance SSS.
D.在SSS扩容数据配置完成后，应该将相关网元的自动容灾切换开关关闭，防止在扩容网元重启过程中用户来回切换，也预防在扩容异常的情况下系统的震荡
After data configurations in SSS expansion are completed, we should disable the automatic disaster-tolerance switchover function on related NEs, so as to avoid back-and-force switchover of users when the expanded NE is restarted, and also avoid system oscillation when an error occurs during expansion.
[单选题]容灾环境SSS扩容前需要停止OSU同步，命令为（ ）。
A.SET OSUDR:SYNCFLAG="O";
B.SET OSUDR:SYNCFLAG="1";
C.SET OSUDR:SYNCFLAG="OFF";
D.SET OSUDR:SYNC="OFF";
[单选题]SSS扩容后，如果想检查系统模块负荷是否均匀，可以通过网管的（ ）功能中各模块用户分布情况查询。
A.性能管理
B.动态管理
C.内存库维护
D.实时观察
[单选题]SSS扩容时涉及到UDP端口包括（ ）配置。
A.SIP流量均衡模块配置
B.协议UDP端口配置
C.IP分发配置
D.以上都是
[简答题]SSS扩容MRFP时,如果发现无法正常放音,请分析原因。
[多选题]SSS扩容前需要进行系统的备份,通过网管可以进行备份的除了告警数据,性能数据,日志数据,安全数据,单板数据之外，还有（ ）。
A.前台库文件备份
B.信令跟踪任务备份
C.OSU数据
D.配置数据
[多选题]SSS扩容一块业务单板的流程，包括（ ）。
A.准备硬件单板,检查单板的硬件版本系统版本是否符合要求
B.在CMM上增加单板的配置、网管物理配置中增加单板配置及服务集、增加分发配置
C.单板上电后获取版本
D.系统中增加用户容量，修改用户分布配置，然后重起业务模块和OMP模块
E.观察业务运行情况
[多选题]SSS扩容MRFP时,如果发现无法正常放音,可以采用以下（ ）处理步骤进行分析处理。
A.通过探针查看前台r_topoly表,查看网关是否注册成功,如果没有注册成功则后续检查
B.检查链路,包括SCTP和H248是否正常
C.检查是否配置导致和网关之间的H248消息响应失败
D.检查是否是媒体不通导致的方音失败
E.收集现场的故障信息进一步定位
[多选题]SSS扩容描述正确的是（ ）。
Which of the following statements are correct about expansion of the SSS system? ( )
A.SSS扩容过程中如果涉及新扩从框，需要将在主从框7、8槽位base面级联前解除从框上的7、8槽位单板互联
During expansion of the SSS system, if a slave shelf is newly expanded, before cascading the base-plane between slot7&8 on the master&slave shelves, you need to remove the interconnection of boards on slot7&8 on the slave shelf.
B.SSS扩容分为软件扩容和硬件扩容，软件扩容一般只需要扩license
SSS expansion is divided into software expansion and hardware expansion. In software expansion, you usually only need to expand the license.
C.SSS扩容时，在完成模块、用户处理能力以及IP分发表后需要传表，重启前台单板
During SSS expansion, after expanding modules, user processing capacity, and the IP distribution table, we need to synchronize tables and then restart foreground boards.
D.为了使已增加单板生效，模块符合调整非常重要。模块负荷调整结果必须是所有模块负荷之和至少为10000，超过10000也可以
To make the new boards effective, it is critical that we adjust module loads. After adjustment of module loads, the total loads of all modules should be 10000 or higher.
